Metabolic/nutrition programming of the enzyme system in the offspring small intestine

Protein deficiency in female rats diet during pregnancy and lactation resulted in changes of the intestine enzymes activity in posterity in early and late periods of ontogenesis. In the former period, deceleration of sucrase induction, acceleration of lactase suppression and maltase induction, and an earlier occurrence of the adult-type distribution of the intestine alkaline phosphatase, were found. At 2 to 4-month age a reduction of the latter enzyme activity was revealed in the doudenum, jejunum and ileum. The changes in the intestine enzymes activities led to a disorder in intermediary metabolism and to occurrence of "risk diseases".
