Jejunal and ileal absorption of L-leucine has been studied in rats subjected to jejunoileal bypass and in sham-operated rats, for five minute periods, using a perfusion technique. Aminoacid concentrations were: 1, 2.5, 5, 10 and 25 mM. In some experiments methionine was added to determine simple diffusion. The ratio of the active/diffusive components of absorption were calculated at the different luminal aminoacid concentrations in both groups of rats, showing that this ratio was lower in control animals.
采用灌注技术，对接受空肠回肠旁路手术的大鼠和假手术大鼠的空肠和回肠对L-亮氨酸的吸收进行了为期五分钟的研究。氨基酸浓度分别为：1、2.5、5、10和25 mM。在一些实验中添加了蛋氨酸以测定单纯扩散。计算了两组大鼠在不同管腔氨基酸浓度下吸收的主动/扩散成分的比例，结果表明对照组动物的该比例较低。
