Figure 7: Histological structure of rat testis using PAS staining. Positive PAS particles were seen inside cytoplasm of spermatogenesis cells closed to basement membrane in control, combined lead and WSE (200 mg/kg/ day), WSE (100 mg/kg/day) and WSE (200 mg/kg/day) groups. Furthermore, positive PAS particles were shown inside cytoplasm of cells closed to lumen of seminiferous tubule, combined lead and WSE (100 mg/kg/day), and combined lead and vitamin E groups. Black arrows show positive PAS particles. PAS positive reactions in basement membrane are shown by white arrows. Values in parentheses are shown in mg/kg/day.
