Trypsin, Phospholipase-D and Neuraminidase at different concentrations inhibited significantly (P less than 0.001) lysine accumulation in rat intestinal cells, whereas Chymotrypsin did not show any significant effect. Trypsin, Chymotrypsin and Phospholipase-D did not show any significant change in lysine accumulation when incubated with mucosal strips isolated from turtle intestine; however, Neuraminidase caused a significant decrease in lysine uptake by these strips. Unidirectional lysine influx across the rat small intestine was significantly reduced (P less than 0.01) by the presence of Trypsin, Phospholipase-D and Neuraminidase in the preincubation solution, and its influx across the turtle small intestine was significantly inhibited (P less than 0.01) by Neuraminidase only. The cell water content and the cell volume were not altered by preincubating the intestinal tissues with any of the enzymes in both animals.
不同浓度的胰蛋白酶、磷脂酶 - D和神经氨酸酶显著抑制（P小于0.001）大鼠肠道细胞中赖氨酸的积累，而胰凝乳蛋白酶则未显示出任何显著影响。当与从龟肠道分离的黏膜条一起孵育时，胰蛋白酶、胰凝乳蛋白酶和磷脂酶 - D在赖氨酸积累方面未显示出任何显著变化；然而，神经氨酸酶导致这些黏膜条对赖氨酸的摄取显著减少。预孵育溶液中存在胰蛋白酶、磷脂酶 - D和神经氨酸酶会显著降低（P小于0.01）赖氨酸单向流入大鼠小肠的量，并且只有神经氨酸酶会显著抑制（P小于0.01）其流入龟小肠的量。用任何一种酶对两种动物的肠道组织进行预孵育均未改变细胞含水量和细胞体积。
