[The circadian rhythms of the hydrolytic enzyme activity of the small intestine in fasting and satiated rats].
The maximal activity of membrane enzymes (carbohydrases, alkaline phosphatase, aminopeptidase) was demonstrated in the evening, but that of cytosolic dipeptidases--at night and at day. This is possibly connected with the different functions of the enzymes--digestive or catabolic, resp. The circadian rhythm did not depend on functional states. The circadian rhythms of the enzymes activities were more expressed in the epithelial layer of the small intestine than in the subepithelial (stromal and muscle-serosal) ones.
