Abstract
The data on the effect of total X-ray irradiation (1.0; 2.0; 3.0 Gy) on transport of Ca2+ and L-phenylalanine by brush-border (BB) membranes of rat small intestine were obtained. The increase of uptake rate for Ca2+ by BB membrane preparations together with the enhancement of the process of L-phenylalanine passive diffusion and suppression of Na(+)-dependent transport of this amino acid was established.
摘要
获得了关于总X射线照射（1.0；2.0；3.0戈瑞）对大鼠小肠刷状缘（BB）膜转运Ca2+和L-苯丙氨酸影响的数据。确定了BB膜制剂对Ca2+摄取率的增加，同时L-苯丙氨酸被动扩散过程增强以及该氨基酸的Na(+)-依赖性转运受到抑制。
