Figure 3.

Hematoxylin and Eosin staining of renal tissues of control (Con) rats and rats treated with different doses of KBrO₃ (PB) with or without gum acacia (GA). Different sections in the figure represent the following groups: (A) Con; (B) GA; (C) PB 5 mg/kg; (D) PB 5 mg/kg plus GA; (E) PB 15 mg/kg; (F) PB 15 mg/kg plus GA; (G) PB 45 mg/kg; (H) PB 45 mg/kg plus GA; (I) PB 135 mg/kg; and (J) PB 135 mg/kg plus GA. Sections (A, B and D) showed normal kidney histological appearance. Section (C) showed minimal histopathological degeneration. ‘*’ indicate dilated tubule. Sections (E, G and I) showed apoptotic cells (thick arrow), and necrotic tubule ‘@’. Partial ameliorations in necrotic and degenerative field were seen in sections (F, H and J) (thick arrows: tubular cast; thin arrows: apoptotic cells). (×400; Bars: 65 µm).
