Masson’s trichrome staining of the kidney sections of (A) normal kidney tissues (negative control) showing slight amounts of blue-stained collagen fibers in glomeruli (blue arrows) (×100); (B) group I showing a marked increase in the abnormal collagen deposition in the walls of tubules (blue arrows) (×100); (C) group II showing vascular congestion with focal blue-stained collagen fibers deposition around the vessels (blue arrows), no collagen deposition in the tubules (×100); (D) group III showing a marked reduction in the abnormal collagen fibers deposition and slight amounts in the glomeruli (blue arrows), with no collagen deposition in the tubules or the blood vessels (×100).
