Figure 4: Light photomicrograph of PAS stained sections of rat renal cortex showing 4A) an even positive PAS reaction ditributed within the brush border (arrow) of proximal tubules (P) and in the basal membrane of both proximal and distal (D) tubules (arrow head). As well as, a positive PAS reaction is seen within the outer membrane (*) of the Bowman’s capsule (C) in control rats; 4B) positive PAS-reaction are seen in few proximal tubules (P) that have intact brush border (arrow) and in the basement membrane (arrow head) of both proximal and distal tubules (D) in cisplatin-treated rats. Positive PAS reactions (arrow) are observed in the brush border (arrow) of the proximal tubules (P), in the basal membrane (arrow head) of both proximal and distal (D) tubules and in the outer membrane of the Bowman’s capsule (*) in misoprostol-treated rats (4C) and in combined misoprostol+ cisplatin-treated rats. G: glomerulus.
