title: Effect of chloramphenicol on the activity of alkaline phosphatase (EC 3.1.3.1.) and the structure of microvilli of the epithelial cells of the small intestine of the hen.
abstract: Effect of a therapeutic dose of chloramphenicol (detreomycin) on the intensity of reaction of alkaline phosphatase and on the structure of microvilli of the epithelial cells of the small intestine of the hen was investigated. It was observed that this antibiotic given orally weakened the intensity of the reaction of alkaline phosphatase and changes also the shape of microvilli of intestinal epithelium. 4 weeks after chloramphenicol administration the activity of the enzyme appeared to be normal and the morphology restored. We concluded from the experiments performed, that chloraphenicol may inhibit the process of protein glycosylation in the enterocytes of the small intestine and also weakened reversible the process of absorption.
