[Mother thyroid status and development of enzymes of initial and final phases of carbohydrate hydrolysis].

Abstract

The daily treatment of a lactating mother with thyroxine 50 micrograms/100 g b.w. from the first to 21st day of lactation resulted in an increase of the thyroxine level in serum and earlier induction of alpha-glycosidases (pancreatic alpha-amylase and enteral maltase, saccharase) and in the earlier repression of beta-galactosidases (intestinal lactase) in rats. In contrast, sucklings fed by hypothyroid mothers showed a low level of thyroxine and a delayed induction of alpha-glucosidases but ameliorated the repression of lactase.
