Mallory’s trichrome 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. Sections C and E: Showed minimal interstitial fibrosis. Sections G and I: Showed large areas of interstitial fibrosis (arrows). Sections F, H and J: Showed decrease in fibrosis (arrows). (×400; Bars: 65 µm).
