[The effect of malnutrition during milk feeding on the enzyme activity of the initial and final stages of carbohydrate hydrolysis in the small intestine of growing rats].

Malnutrition in the period from 10 to 17 days of postnatal life causes in young rats an early increase of intestinal alpha-glucosidase activity. However, this rise in the enzyme activity is soon changed by its decrease during normal nutrition. The decreased level of the enzyme activity remains stable during 2-3 weeks after the reduction of normal nutrition.
