[Cell respiration intensity and redox state of NAM-coenzymes in small intestine epithelium of newborn calves in health and in diarrhea].

It has been established that mucous membrane of jejunum and stomach tissue of 3-4-day calves are characterized by high intensity of glycolytic and aerobic processes. Digestion disorders with diarrheic symptoms are accompanied by changes in levels and relations in NAD (P)(+)-dependent dehydrogenase metabolites reduction of lactate- and succinate dehydrogenases, alkaline phosphatase and gamma-glutamyltransferase activities in cytoplasm and mitochondria of proximal and distal parts of the jejunum in comparison with clinically normal animals.
