1.通过不受限制地获取食物的大鼠的离体小肠吸收的葡萄糖和水在夜间比白天高50 - 60%。2.当喂食时间限制在06.00 - 09.00 hr G.M.T.时在禁食后3 - 7小时内，葡萄糖和水的吸收率几乎与在无限制喂养的动物中观察到的夜间吸收率一样高。3.这些吸收率的变化似乎与进食时间，而不是与照明模式。
1. Glucose and water absorption by isolated small intestine from rats which have had unrestricted access to food is 50‐60% higher at night than during the daytime. 2. When the feeding time is restricted to 06.00‐09.00 hr G.M.T. glucose and water absorption rates in the period from 3 to 7 hr after withdrawal of food are almost as high as the rates observed at night‐time in the animals with unrestricted feeding. 3. These changes in absorption rates appear to be associated with feeding time and not with the pattern of illumination.
