    e of the study was to investigate the pertinence of var-kers of cardiac toxicity in the minipig.tigen 10-month-old male minipigs were used. A Millaressure transducer was inserted into the left ventriclecarotid artery of each minipig. The left jugular veinrised with a polyethylene 6F catheter for blood sam-

Twoceived 6mg/kg infused intravenously over 1h. Thenimals received 0.5mg/kg by the subcutaneous route.ventricular pressure and electrocardiogram (lead IIwere continuously recorded using Notocord-hem v.3.4lood samples were taken before dosing and at vari-oints up to 150min after dosing and used for clinicaldeterminations. The parameters evaluated includedserum amyloid A (SAA), aspartate aminotransferaseine aminotransferase (ALAT) and creatine kinase (CK).ological examination of the heart was performed for all
