Figure 8: Histological structure of rat testis using Sudan black staining. Sufficient amounts of lipids were seen in Leydig cells (white arrows) and spermatogenesis cells (black arrows) in control group. Combined Lead and WSE (200 mg/kg/day), WSE (100 mg/kg/day) and WSE (200 mg/kg/day) groups showed an increase in storage amount of lipids in all cells. On the contrary, lead, combined lead and WSE (100 mg/kg/day), and combined lead and vitamin E groups showed a decrease in storage amount of lipids in all cells. Values in parentheses are shown in mg/kg/day.
