[Changes in the epithelium of the proximal part of the nephron tubule after bile loss by the body].

As demonstrate the experiments performed in 45 male rats of Wistar line, a complete bile loss by the organism results in 24-72 h in certain distrophic changes of epithelium in the proximal parts of the nephron canaliculi. The brush border microvilli undergo destruction, the cellular membranes disorganize, cytoplasm of epitheliocytes vacuolizes up to their complete rupture. The PAS-positive reaction of the basal membrane in the canaliculi increases. In cytoplasm of epitheliocytes in the straight portions of the canaliculi of the distal parts of the nephron glycogene is deposited. Alkaline phosphatase, succinate dehydrogenase, cytochromoxydase activity decreases, and that of acidic phosphatase increases. The changes advance with increasing time from the beginning of bile loss.
