Abstract

The changes in intestinal disaccharidase activities in pregnancy and lactation could be explained as a result of an adaptation to the energy demands of each reproductive stage. To examine these changes, disaccharidase activities (lactase, sucrase, maltase, and trehalase) were measured in the jejunum and ileum of virgin, pregnant and lactating Wistar rats. Minor changes in disaccharidase activities were observed in pregnancy, whereas an increase of disaccharidase activities per small intestine length normalized to body mass was observed in lactation.

摘要

妊娠和哺乳期肠道双糖酶活性的变化可以解释为是对每个生殖阶段能量需求的一种适应结果。为了研究这些变化，对未交配的、怀孕的和哺乳的Wistar大鼠的空肠和回肠中的双糖酶活性（乳糖酶、蔗糖酶、麦芽糖酶和海藻糖酶）进行了测量。在妊娠期间观察到双糖酶活性有轻微变化，而在哺乳期，以体重标准化的每小肠长度的双糖酶活性有所增加。
