Effect of sodium nitrite on the alpha-chlorohydrin-induced lesion of the testis--epididymis complexin the rat.

Administration of vasodilator, sodium nitrite (20 mg/kg body weight), 30 min before alpha-chlorohydrin treatment (90 mg/kg body weight) prevented the chlorohydrin-induced lesion in rat testis--epididymis complex. However, administration of vasodilator 90 min after alpha-chlorohydrin treatment did not prevent the chlorohydrin-induced lesion in the testis--epididymis complex. These observations suggest that the testicular vasculature is involved in drug action.
