The relative concentration of various immunoglobulins attain in the sera of 14-day-old rats have been compared 4 h after their oral and intraluminal administration. The circulatory concentration of these proteins attained higher values when they were administered into the isolated proximal small intestina than when they were administered into the distal small intestine. Selective uptake of proteins was shown to predominate in the proximal small intestine.
对14日龄大鼠经口和肠腔内给药4小时后血清中各种免疫球蛋白的相对浓度进行了比较。当将这些蛋白质注入离体近端小肠时，其循环浓度比注入远端小肠时更高。结果表明，近端小肠中蛋白质的选择性吸收占主导地位。
