A rat jejunal segment of 15 cm length was perfused single pass with a 3 mmol/l sucrose solution 4 times daily at 8.00, 14.00, 20.00 and 2.00. One group of rats was fed ad libitum, a second group was "meal fed" between 14.00 and 18.00. Sucrose absorption reached its maximum at 8.00 in the rats fed ad libitum whereas it was spread over a period of six hours (20.00-2.00) in the meal fed rats. The activity of sucrase in mucosal scrapings reached its peak at feeding time.
取一段15厘米长的大鼠空肠段，每天4次在8:00、14:00、20:00和2:00用3毫摩尔/升的蔗糖溶液进行单程灌注。一组大鼠随意进食，另一组大鼠在14:00至18:00之间“定时进食”。随意进食的大鼠蔗糖吸收在8:00达到最大值，而定时进食的大鼠蔗糖吸收则在6小时内（20:00至2:00）完成。喂食时，黏膜刮片中蔗糖酶的活性达到峰值。
