Effect of allopurinol on germ cell apoptosis following testicular ischemia–reperfusion injury in a rat

Recent evidence suggests that apoptosis is involved in germ cell loss following testicular ischemia-reperfusion (IR) injury. Allopurinol (Allo) is as a free radical scavenger which prevents tissue damage caused by reperfusion and oxygenation after ischemia; however, its effect on apoptosis in this t...

description Recent evidence suggests that apoptosis is involved in germ cell loss following testicular ischemia-reperfusion (IR) injury. Allopurinol (Allo) is as a free radical scavenger which prevents tissue damage caused by reperfusion and oxygenation after ischemia; however, its effect on apoptosis in this type of injury has not been studied. To examine the effect of allopurinol on germ cell apoptosis following testicular IR in a rat. Forty rats were divided randomly into 4 experimental groups of 10 rats each: group A (Sham)-Sham operated animals; group B (Sham-Allo)-Sham operated rats treated with allopurinol given PO (by gavage) at a dose of 200 mg/kg, once daily, immediately before and 24 h following operation; group C (IR)-rats underwent 90 min of unilateral testicular ischemia and 48 h of reperfusion; group D (IR-Allo)-rats underwent IR and were treated with allopurinol similar to group B. The ipsilateral and contralateral testes were harvested 48 h following operation. Johnsen’s criteria and the number of germinal cell layers were used to categorize spermatogenesis. TUNEL assay was used to determine germ cell apoptosis. Statistical analysis was performed using one-way ANOVA test, with P

Germ cell apoptosis in both the ischemic and the contralateral testis increased significantly after IR. Treatment with allopurinol resulted in a significant decrease in germ cell apoptosis in the ipsilateral testis, expressed as the number of positive tubules per 100 tubules (AI-1, (apoptotic index) threefold decrease, P  < 0.005) and the number of apoptotic cells per 100 tubules (AI-2, fivefold decrease, P  < 0.005) as well as a significant decrease in germ cell apoptosis in the contralateral testis (AI-1, 3.5-fold decrease, P  < 0.05, AI-2- sixfold decrease, P  < 0.005) compared to IR animals.
