1 Introduction

One of the animals which represent Pakistan and Indiathroughout the world is cobra in particular it is rearing out ofa wicker basket and dancing to the sound of turban-wearingsnake charmer music In fact they are deadly venomousamong all species of the snakes due to high rate of mortalitywhich strongly reasoned for their notoriety [1] At the endof the nineteenth century all cobra populations have beenmerged into single species naja (formerly known as naia)

however subsequently ten subspecies of Naja naja wereidentified [1] Later on Deraniyagala classified Naja naja(India) into several subspecies and considered Naja najakarachiensis one of them widely distributed in SouthernPunjab province of Pakistan [2] They are extremely toxicdue to their severe side effects in the victims Major signsand symptoms of cobra envenomation are edema necrosispain respiratory paralysis vomiting headache hypotensioncardiac arrest coagulopathies (elevated PT aPTT and TT)bleeding wounds hematuria mucus discharge proteinuria

and increased creatinine and urea levels along with alteredconsciousness [3 4]

Indeed snake venom is a complex mixture of varioussizes of polypeptides [5 6] (lt15 kDa 5 to 10 kDa and10 to 150 kDa) carbohydrates lipids metal ions organicmolecules purines and amines [7 8] Snake bite enveno-mation has been attributed to pose drastic changes in thephysiology of the victims that could be accessed clinicallyby measuring various biochemical parameters Among toxiccomponents phospholipases A

Laboratory animals particularly rabbits have beenselected previously to monitor various biochemical changesrelated to liver heart and renal toxicities [18 19] Aspartateaminotransferase (GOTAST) and alanine aminotransferase(GPTALT) are surrogate markers for liver toxicities whilecreatine kinase isoenzyme (CK-MB) is used exclusively toaccess cardiac tissue damage [20 21] Elevated creatinine andurea levels are indicators of 75 renal damage [20] whereashigh level of lactate dehydrogenase (LDH) implies generaltoxicity related to the liver heart kidneys and skeletonmuscles [22]

Diverse immunological properties of different cobrashave fascinated protein chemists and other researchers tocarry out efforts for the development of new antidotes Dueto this reason for the first time venom from Naja najakarachiensis is selected to evaluate its toxicity in vivo andto search out effective as well as cheap treatment fromfolk herbal remedies Pakistan is a hub of medicinal plantswhere mostly rural communities rely on natural herbs totreat their problems of snake bite [6 23] It is thereforenecessary to evaluate scientifically their folklore claims asanti-snake venom in traditional system of medicine Dueto this reason various medicinal plants (Albizia lebbeck (L)Benth Allium cepa L Allium sativum L Althaea officinalisL Bauhinia variegata L Brassica nigra (L) W D J KochCalotropis procera (Aiton)WTAitonCedrus deodara (Roxbex D Don) G Don Citrullus colocynthis (L) Schrad Citruslimon (L) Burm f Cuminum cyminum L Enicostemahyssopifolium (Willd) I Verd Fagonia cretica L Leucascapitata DesfMatthiola incana (L) W T AitonMomordicacharantiaLNerium indicumMillOcimum sanctumL Pinusroxburghii Sarg Pistacia integerrima J L Stewart Psoraleacorylifolia L Rhazya stricta Decne Rubia cordifolia LSapindus mukorossi Gaertn Solanum xanthocarpum Schardand Wendle Stenolobium stans (L) Seem Terminalia arjuna(Roxb exDC)Wight andArnTrichodesma indicum (L) Smand Zingiber officinale Roscoe) were collected to test theirpotentials against toxicities induced byNaja naja karachiensisenvenomation (Table 1)

2 Material and Methods

21 Collection and Milking of Snake Venom Black Pakistanicobra snakes (Naja naja karachiensis) were collected fromCholistan desert located in southern Punjab province ofPakistan After collection they were properly identified by azoologist Venom from Naja naja karachiensis was collectedby pressing their glands below their eyes in low light environ-ment After collection it was lyophilized and stored in lightresistant container at 2∘C to 8∘C For further experimentsvenom was used in terms of its dry weight [6]

22 Collection and Preparation of Plant Extracts Medicinalplants were collected from different areas in Pakistan Aftercollection they were duly identified by expert botanist(Professor Dr Altaf Ahmad Dasti) and voucher specimenswere deposited in the herbarium of the Institute of Pure andApplied Biology Bahauddin Zakariya University MultanPakistan Complete description about evaluated medicinalplants is summarized in Table 1 One kilogram choppedplant material was soaked in 5 L of methanol as solvent inextraction bottlesThe homogenates were kept for a period ofa month at optimum temperature After filtration filtrate wasevaporated by using water bath and extracts were weighedand stored for further experimentation [24]

23 Experimental Animals Seventy-one healthy growingmale rabbits (1 plusmn 05 kg) were selected for this study aftergetting permission from local ethical committee Animalswere acclimatized for a week in the laboratory bymaintainingtheir standards for chow water and light Subsequently theywere divided into various groups in different cages suchthat experimental rabbits in group I were used for baselinemeasurements of various biochemical parameters Animalsbelonging to groups II and III were evaluated for differentdoses of cobra venom while group IV was served as controlGroup V was redivided into twenty-nine groups such thateach subgroup (V1ndashV29) was assigned to a single medicinalplant extract [25]

24 In Vivo Antivenom Activity of Medicinal Plant ExtractsVenom from Naja naja karachiensis (400 120583gkg and800 120583gkg) was injected subcutaneously to evaluate itstoxicity to the heart liver and kidneys Before injectionof venom experimental animals were anaesthetizedby administration of ketamine (50mgkg) To determineantivenomactivity of various plantsrsquo extract they (100mgkg)were incubated (at 37∘C for 30 minutes) with fixed amountof venom (800120583gkg) before injection while saline was usedas control [26ndash28]

25 Biochemical Assays For serum analysis of various bio-chemical parameters blood was collected from marginal earartery by the use of hypodermic syringe needle after 3 hoursof envenomation [25] Separated serumwas tested for alanineaminotransferase (GPTALT) aspartate aminotransferase(GOTAST) urea creatinine creatine kinase isoenzyme MB(CK-MB) and lactate dehydrogenase (LDH) by the use of

Generally snake venom is an intricate mixture of variousproteins (gt90) and most of them are enzymes particularly(40) phospholipases A

2[30] Among different complica-

tions hepatic injury is one of the deadly venomous effectsproduced by cobra bite [31 32] Naja naja karachiensisvenom caused significant increase in ALT and AST levels(dose dependently) that are surrogate markers for livertoxicity either by direct action or immunological (hyper-sensitivity) reaction The allergic reactions reactions are notdose dependent which clarify lethal effects to the cytoplasm

and mitochondrial membranes of the hepatic cells [25 33]Phospholipases enzymes abundant in Naja naja karachien-sis venom are responsible for breakdown of membranousphospholipids and therefore resulted in cellular injury alongwith inflammation [24] PLA

2is attributed to decrease in

Na+K+ ATPase activities and led to greater influx of sodiumions and water molecules into the cell Subsequently plasmamembrane lipid bilayer disorganized and eventually resultedin hepatic cells death [33 34] In addition PLA

2is also found

to cause anticoagulation in victims [6] All pharmacological

effects are due to phospholipid hydrolysis or phospholipidcompeting bidingmechanismwith other coagulation factorsparticularly FXa or by both ways however it is very hardto pinpoint exact one [35] Anticoagulant response posed bycobra PLA

2(anticoagulant enzyme) may aggravate hepatic

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

and increased creatinine and urea levels along with alteredconsciousness [3 4]

Indeed snake venom is a complex mixture of varioussizes of polypeptides [5 6] (lt15 kDa 5 to 10 kDa and10 to 150 kDa) carbohydrates lipids metal ions organicmolecules purines and amines [7 8] Snake bite enveno-mation has been attributed to pose drastic changes in thephysiology of the victims that could be accessed clinicallyby measuring various biochemical parameters Among toxiccomponents phospholipases A

Laboratory animals particularly rabbits have beenselected previously to monitor various biochemical changesrelated to liver heart and renal toxicities [18 19] Aspartateaminotransferase (GOTAST) and alanine aminotransferase(GPTALT) are surrogate markers for liver toxicities whilecreatine kinase isoenzyme (CK-MB) is used exclusively toaccess cardiac tissue damage [20 21] Elevated creatinine andurea levels are indicators of 75 renal damage [20] whereashigh level of lactate dehydrogenase (LDH) implies generaltoxicity related to the liver heart kidneys and skeletonmuscles [22]

Diverse immunological properties of different cobrashave fascinated protein chemists and other researchers tocarry out efforts for the development of new antidotes Dueto this reason for the first time venom from Naja najakarachiensis is selected to evaluate its toxicity in vivo andto search out effective as well as cheap treatment fromfolk herbal remedies Pakistan is a hub of medicinal plantswhere mostly rural communities rely on natural herbs totreat their problems of snake bite [6 23] It is thereforenecessary to evaluate scientifically their folklore claims asanti-snake venom in traditional system of medicine Dueto this reason various medicinal plants (Albizia lebbeck (L)Benth Allium cepa L Allium sativum L Althaea officinalisL Bauhinia variegata L Brassica nigra (L) W D J KochCalotropis procera (Aiton)WTAitonCedrus deodara (Roxbex D Don) G Don Citrullus colocynthis (L) Schrad Citruslimon (L) Burm f Cuminum cyminum L Enicostemahyssopifolium (Willd) I Verd Fagonia cretica L Leucascapitata DesfMatthiola incana (L) W T AitonMomordicacharantiaLNerium indicumMillOcimum sanctumL Pinusroxburghii Sarg Pistacia integerrima J L Stewart Psoraleacorylifolia L Rhazya stricta Decne Rubia cordifolia LSapindus mukorossi Gaertn Solanum xanthocarpum Schardand Wendle Stenolobium stans (L) Seem Terminalia arjuna(Roxb exDC)Wight andArnTrichodesma indicum (L) Smand Zingiber officinale Roscoe) were collected to test theirpotentials against toxicities induced byNaja naja karachiensisenvenomation (Table 1)

2 Material and Methods

21 Collection and Milking of Snake Venom Black Pakistanicobra snakes (Naja naja karachiensis) were collected fromCholistan desert located in southern Punjab province ofPakistan After collection they were properly identified by azoologist Venom from Naja naja karachiensis was collectedby pressing their glands below their eyes in low light environ-ment After collection it was lyophilized and stored in lightresistant container at 2∘C to 8∘C For further experimentsvenom was used in terms of its dry weight [6]

22 Collection and Preparation of Plant Extracts Medicinalplants were collected from different areas in Pakistan Aftercollection they were duly identified by expert botanist(Professor Dr Altaf Ahmad Dasti) and voucher specimenswere deposited in the herbarium of the Institute of Pure andApplied Biology Bahauddin Zakariya University MultanPakistan Complete description about evaluated medicinalplants is summarized in Table 1 One kilogram choppedplant material was soaked in 5 L of methanol as solvent inextraction bottlesThe homogenates were kept for a period ofa month at optimum temperature After filtration filtrate wasevaporated by using water bath and extracts were weighedand stored for further experimentation [24]

23 Experimental Animals Seventy-one healthy growingmale rabbits (1 plusmn 05 kg) were selected for this study aftergetting permission from local ethical committee Animalswere acclimatized for a week in the laboratory bymaintainingtheir standards for chow water and light Subsequently theywere divided into various groups in different cages suchthat experimental rabbits in group I were used for baselinemeasurements of various biochemical parameters Animalsbelonging to groups II and III were evaluated for differentdoses of cobra venom while group IV was served as controlGroup V was redivided into twenty-nine groups such thateach subgroup (V1ndashV29) was assigned to a single medicinalplant extract [25]

24 In Vivo Antivenom Activity of Medicinal Plant ExtractsVenom from Naja naja karachiensis (400 120583gkg and800 120583gkg) was injected subcutaneously to evaluate itstoxicity to the heart liver and kidneys Before injectionof venom experimental animals were anaesthetizedby administration of ketamine (50mgkg) To determineantivenomactivity of various plantsrsquo extract they (100mgkg)were incubated (at 37∘C for 30 minutes) with fixed amountof venom (800120583gkg) before injection while saline was usedas control [26ndash28]

25 Biochemical Assays For serum analysis of various bio-chemical parameters blood was collected from marginal earartery by the use of hypodermic syringe needle after 3 hoursof envenomation [25] Separated serumwas tested for alanineaminotransferase (GPTALT) aspartate aminotransferase(GOTAST) urea creatinine creatine kinase isoenzyme MB(CK-MB) and lactate dehydrogenase (LDH) by the use of

Generally snake venom is an intricate mixture of variousproteins (gt90) and most of them are enzymes particularly(40) phospholipases A

2[30] Among different complica-

tions hepatic injury is one of the deadly venomous effectsproduced by cobra bite [31 32] Naja naja karachiensisvenom caused significant increase in ALT and AST levels(dose dependently) that are surrogate markers for livertoxicity either by direct action or immunological (hyper-sensitivity) reaction The allergic reactions reactions are notdose dependent which clarify lethal effects to the cytoplasm

and mitochondrial membranes of the hepatic cells [25 33]Phospholipases enzymes abundant in Naja naja karachien-sis venom are responsible for breakdown of membranousphospholipids and therefore resulted in cellular injury alongwith inflammation [24] PLA

2is attributed to decrease in

Na+K+ ATPase activities and led to greater influx of sodiumions and water molecules into the cell Subsequently plasmamembrane lipid bilayer disorganized and eventually resultedin hepatic cells death [33 34] In addition PLA

2is also found

to cause anticoagulation in victims [6] All pharmacological

effects are due to phospholipid hydrolysis or phospholipidcompeting bidingmechanismwith other coagulation factorsparticularly FXa or by both ways however it is very hardto pinpoint exact one [35] Anticoagulant response posed bycobra PLA

2(anticoagulant enzyme) may aggravate hepatic

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

Generally snake venom is an intricate mixture of variousproteins (gt90) and most of them are enzymes particularly(40) phospholipases A

2[30] Among different complica-

tions hepatic injury is one of the deadly venomous effectsproduced by cobra bite [31 32] Naja naja karachiensisvenom caused significant increase in ALT and AST levels(dose dependently) that are surrogate markers for livertoxicity either by direct action or immunological (hyper-sensitivity) reaction The allergic reactions reactions are notdose dependent which clarify lethal effects to the cytoplasm

and mitochondrial membranes of the hepatic cells [25 33]Phospholipases enzymes abundant in Naja naja karachien-sis venom are responsible for breakdown of membranousphospholipids and therefore resulted in cellular injury alongwith inflammation [24] PLA

2is attributed to decrease in

Na+K+ ATPase activities and led to greater influx of sodiumions and water molecules into the cell Subsequently plasmamembrane lipid bilayer disorganized and eventually resultedin hepatic cells death [33 34] In addition PLA

2is also found

to cause anticoagulation in victims [6] All pharmacological

effects are due to phospholipid hydrolysis or phospholipidcompeting bidingmechanismwith other coagulation factorsparticularly FXa or by both ways however it is very hardto pinpoint exact one [35] Anticoagulant response posed bycobra PLA

2(anticoagulant enzyme) may aggravate hepatic

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

Generally snake venom is an intricate mixture of variousproteins (gt90) and most of them are enzymes particularly(40) phospholipases A

2[30] Among different complica-

tions hepatic injury is one of the deadly venomous effectsproduced by cobra bite [31 32] Naja naja karachiensisvenom caused significant increase in ALT and AST levels(dose dependently) that are surrogate markers for livertoxicity either by direct action or immunological (hyper-sensitivity) reaction The allergic reactions reactions are notdose dependent which clarify lethal effects to the cytoplasm

and mitochondrial membranes of the hepatic cells [25 33]Phospholipases enzymes abundant in Naja naja karachien-sis venom are responsible for breakdown of membranousphospholipids and therefore resulted in cellular injury alongwith inflammation [24] PLA

2is attributed to decrease in

Na+K+ ATPase activities and led to greater influx of sodiumions and water molecules into the cell Subsequently plasmamembrane lipid bilayer disorganized and eventually resultedin hepatic cells death [33 34] In addition PLA

2is also found

to cause anticoagulation in victims [6] All pharmacological

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

Generally snake venom is an intricate mixture of variousproteins (gt90) and most of them are enzymes particularly(40) phospholipases A

2[30] Among different complica-

tions hepatic injury is one of the deadly venomous effectsproduced by cobra bite [31 32] Naja naja karachiensisvenom caused significant increase in ALT and AST levels(dose dependently) that are surrogate markers for livertoxicity either by direct action or immunological (hyper-sensitivity) reaction The allergic reactions reactions are notdose dependent which clarify lethal effects to the cytoplasm

and mitochondrial membranes of the hepatic cells [25 33]Phospholipases enzymes abundant in Naja naja karachien-sis venom are responsible for breakdown of membranousphospholipids and therefore resulted in cellular injury alongwith inflammation [24] PLA

2is attributed to decrease in

Na+K+ ATPase activities and led to greater influx of sodiumions and water molecules into the cell Subsequently plasmamembrane lipid bilayer disorganized and eventually resultedin hepatic cells death [33 34] In addition PLA

2is also found

to cause anticoagulation in victims [6] All pharmacological

effects are due to phospholipid hydrolysis or phospholipidcompeting bidingmechanismwith other coagulation factorsparticularly FXa or by both ways however it is very hardto pinpoint exact one [35] Anticoagulant response posed bycobra PLA

2(anticoagulant enzyme) may aggravate hepatic

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

Generally snake venom is an intricate mixture of variousproteins (gt90) and most of them are enzymes particularly(40) phospholipases A

2[30] Among different complica-

tions hepatic injury is one of the deadly venomous effectsproduced by cobra bite [31 32] Naja naja karachiensisvenom caused significant increase in ALT and AST levels(dose dependently) that are surrogate markers for livertoxicity either by direct action or immunological (hyper-sensitivity) reaction The allergic reactions reactions are notdose dependent which clarify lethal effects to the cytoplasm

and mitochondrial membranes of the hepatic cells [25 33]Phospholipases enzymes abundant in Naja naja karachien-sis venom are responsible for breakdown of membranousphospholipids and therefore resulted in cellular injury alongwith inflammation [24] PLA

2is attributed to decrease in

Na+K+ ATPase activities and led to greater influx of sodiumions and water molecules into the cell Subsequently plasmamembrane lipid bilayer disorganized and eventually resultedin hepatic cells death [33 34] In addition PLA

2is also found

to cause anticoagulation in victims [6] All pharmacological

effects are due to phospholipid hydrolysis or phospholipidcompeting bidingmechanismwith other coagulation factorsparticularly FXa or by both ways however it is very hardto pinpoint exact one [35] Anticoagulant response posed bycobra PLA

2(anticoagulant enzyme) may aggravate hepatic

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

Generally snake venom is an intricate mixture of variousproteins (gt90) and most of them are enzymes particularly(40) phospholipases A

2[30] Among different complica-

tions hepatic injury is one of the deadly venomous effectsproduced by cobra bite [31 32] Naja naja karachiensisvenom caused significant increase in ALT and AST levels(dose dependently) that are surrogate markers for livertoxicity either by direct action or immunological (hyper-sensitivity) reaction The allergic reactions reactions are notdose dependent which clarify lethal effects to the cytoplasm

and mitochondrial membranes of the hepatic cells [25 33]Phospholipases enzymes abundant in Naja naja karachien-sis venom are responsible for breakdown of membranousphospholipids and therefore resulted in cellular injury alongwith inflammation [24] PLA

2is attributed to decrease in

Na+K+ ATPase activities and led to greater influx of sodiumions and water molecules into the cell Subsequently plasmamembrane lipid bilayer disorganized and eventually resultedin hepatic cells death [33 34] In addition PLA

2is also found

to cause anticoagulation in victims [6] All pharmacological

effects are due to phospholipid hydrolysis or phospholipidcompeting bidingmechanismwith other coagulation factorsparticularly FXa or by both ways however it is very hardto pinpoint exact one [35] Anticoagulant response posed bycobra PLA

2(anticoagulant enzyme) may aggravate hepatic

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

Generally snake venom is an intricate mixture of variousproteins (gt90) and most of them are enzymes particularly(40) phospholipases A

2[30] Among different complica-

tions hepatic injury is one of the deadly venomous effectsproduced by cobra bite [31 32] Naja naja karachiensisvenom caused significant increase in ALT and AST levels(dose dependently) that are surrogate markers for livertoxicity either by direct action or immunological (hyper-sensitivity) reaction The allergic reactions reactions are notdose dependent which clarify lethal effects to the cytoplasm

and mitochondrial membranes of the hepatic cells [25 33]Phospholipases enzymes abundant in Naja naja karachien-sis venom are responsible for breakdown of membranousphospholipids and therefore resulted in cellular injury alongwith inflammation [24] PLA

2is attributed to decrease in

Na+K+ ATPase activities and led to greater influx of sodiumions and water molecules into the cell Subsequently plasmamembrane lipid bilayer disorganized and eventually resultedin hepatic cells death [33 34] In addition PLA

to cause anticoagulation in victims [6] All pharmacological

effects are due to phospholipid hydrolysis or phospholipidcompeting bidingmechanismwith other coagulation factorsparticularly FXa or by both ways however it is very hardto pinpoint exact one [35] Anticoagulant response posed bycobra PLA

2(anticoagulant enzyme) may aggravate hepatic

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

effects are due to phospholipid hydrolysis or phospholipidcompeting bidingmechanismwith other coagulation factorsparticularly FXa or by both ways however it is very hardto pinpoint exact one [35] Anticoagulant response posed bycobra PLA

2(anticoagulant enzyme) may aggravate hepatic

injury as many anticoagulant agents cause liver damage thatare idiosyncratic in nature [36]

Cardiac injury particularly systolic heart arrest is one ofthewell-known toxicities related toNaja naja subspecies [30]In present study Pakistani cobra venom was found to release

two cystolic enzymes (LDH and CK-MB) that are sensitiveindicators of myocyte injury [37] It is due to the presenceof myotoxic PLA

2and other cardiotoxin(s) that are salient

features of cobra venom that are responsible for cellularnecrosis and cytotoxicity [38 39] Cytotoxic effect of Najanaja karachiensis venom may not be overlooked even whenantisera administration is late cause of toxic components tothe microvasculature and thrombus produced which poseshindrance in access of immunoglobulins to the site of snakebite [26 29 39]

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom

Figure 2 Comparison of various medicinal plant extracts with reference standard antivenom in neutralization of elevated serum urea andcreatinine level posed by Naja naja karachiensis venom in rabbits

Snake venom has been responsible for detrimental effectsto the renal tissues [40] Likewise Naja naja krachiensisvenomwas found to cause severe renal damage by significantrise in serum urea and creatinine levels Indeed phospho-lipases enzymes are responsible for the increase in vascularpermeability with hemorrhagic effects to the vital tissues inthe victims Subsequently numerous lesions are producedrelated to the glomerular membrane and renal tubules eitherinterstitial or vascular [29 41 42] Presence of lymphocytes(white blood cells) and oedema in the cortical as well asmedullary regions of renal tubules further confirmed theidea of renal damage (data has not shown) as reportedpreviously with different snake venoms like Hemiscorpiuslepturus [26 43] Apart of it pharmacokinetic studies ofNaja naja karachiensis venom with short lived radioisotope99mTc confirmed that kidneys and urinary bladder are themost saturated organs (gt70) after intravenous injection inexperimental rabbits (unpublished data by our group)

Medicinal plants of Pakistan are used to inhibit snakevenom (PLA

2) enzymes [6] Due to this effect present

study was designed to select twenty-eight medicinal plantsof Pakistan to test their potentials as an antidote againsttoxicities produced by Naja naja karachiensis venom It

was fascinating that extract of Stenolobium stans (L) Seemshowed significant neutralization compared to that of refer-ence standard (antisera) as reported previously by Asad etal for inhibition of phospholipases A

2anticoagulant activity

[6 44] Present study indicated that extract of Stenolobiumstans (L) Seem possesses an endogenous inhibitor(s) tonullify venom (PLA

2) induced toxicities Extracts of these

plants material are routinely used in Pakistan by simpleapplication in the form of paste to the affected area [45]This practice provides effective first aid treatment as tinymolecules of an antidote diffuse favorably at the site of snakebite before hospitalization and abrogated the spreading oftoxins [39] It is owing to the various secondary metaboliteslike phenols flavonoids terpenoids xanthenes quinonoidsand so forth as reported earlier to mask various enzymaticactions of cobra venom [6 23] Indeed secondarymetabolitespose hindrance in binding of different snake venom enzymesto their potential targets therefore antidotal effect evokedOther plants extract were not proved significantly effectiveto neutralize cobra venom therefore cannot be declareduseful plants in venom therapy It is the need of the time toisolate lethal component(s) of cobra venom attributed to itsmajor toxicities Furthermore characterization of antivenom
