Abstract
The absorption of glycine, glycylglycine, water, and electrolytes was studied by intestinal perfusion in normal Indian and English people. Compared with the English people the Indians showed impaired absorption of all four substances. In the Indians the absorption of glycine and glycylglycine was impaired to the same extent, so that the kinetic advantage of glycylglycine as compared with glycine was preserved. The reduced absorption in the Indians may be the functional counterpart of the minor morphological changes seen in the jejunal mucosa of people living in southern India.
摘要
通过对正常印度人和英国人进行肠道灌注，研究了甘氨酸、甘氨酰甘氨酸、水和电解质的吸收情况。与英国人相比，印度人这四种物质的吸收均受损。在印度人中，甘氨酸和甘氨酰甘氨酸的吸收受损程度相同，因此甘氨酰甘氨酸相对于甘氨酸的动力学优势得以保留。印度人吸收减少可能是居住在印度南部人群空肠黏膜中所见轻微形态学变化的功能对应表现。
