Abstract:
Observations were carried out on the changes of ?-glutamyl transpeptidase (?-GT) changes in the kidneys and jejunum of the rat fetus and growing rats with histobiochemical methods. In general, the activity of ?-GT in the kidneys . increases with the increase of the age of the rats. In the rat fetus,?-GT is mainly localized on the surface of the metanephros tubular lumen. After the rat is born,R?-GT can be found on the brush border membrane of the proximal convoluted tubules and the epithelium of the Henle's loops as well as on the basement of the epithelium of the proximal convoluted tubules and the capillary walls of the renalfcortex and medulla. In addition, the activity of ?-GT is far more prominent in the deep layer than in the superficial layer of the renal cortex.In the jejunum of the rat fetus, marked activity of ?-GT is only found after the villi of the jejunum are formed: the activity is the highest when the fetus is of 21 days of age and it reduces after the rat is born.
