[Effect of ionizing radiation on membrane transport properties of small intestines].
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.
