uropathy is one of the most common complicationsore than 5060% of diabetic patients and it is a commonn-traumatic amputation and autonomic failure. Neu-roids, such as progesterone (PROG), have been recentlys promising neuroprotective agents in several modelseneration. In this study we investigated the potential
ctive effect of PROG in experimental model of diabetic. Animalswere randomly divided into 3 groups (with 10), control (nondiabetic), untreated diabetic and diabeticed. Diabetes was induced in adult male rats by a singleon of streptozotocin (STZ, 55mgkg1, i.p.). In the PROG-p, 4 weeks after induce of diabetes; rats were treated
