Functioning of Enzyme Systems of Digestive and Non-Digestive Organs in Adult Rats Depends on Quality of Nutrition in Early Ontogenesis

It is revealed that restriction of protein in nutrition of rat pups in early ontogenesis, at the period of transition from the mixed to the definitive nutrition, produces change of structural parameters and functioning of digestive enzymes in various parts of small intestine (duodenum, jejunum, and ileum) and in large intestine as well as of these hydrolases in liver and kidney in adult life. The disturbance of quality of nutrition in early ontogenesis seems to affect negatively digestive functions of small intestine and trophic-barrier function of large intestine, liver, and kidney, which can promote development of diseases not only of the gastrointestinal tract, but also of other organs.
