Abstract
  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.
摘要
  1. 对食物摄取不受限制的大鼠,其离体小肠对葡萄糖和水的吸收在夜间比白天高50%-60%。2. 当喂食时间限制在协调世界时06:00-09:00时,禁食3至7小时期间的葡萄糖和水吸收速率几乎与食物摄取不受限制的动物在夜间观察到的速率一样高。3. 这些吸收速率的变化似乎与喂食时间有关,而与光照模式无关。
