Abstract

Under conditions of an increase in the carbonic acid concentration in blood of rabbits (experimental group) utilization of ammonia nitrogen administered to the organism intensifies and simultaneously the level of keto-acids in blood as well as of free amino acids and urea in the liver tissue increases. In these animals as compared to the control ones the content of glutamine in blood and in the liver tissue decreases; the level of alpha-glutarate and glutamate in the liver tissue increases and that of pyruvate lowers. An increase is also observed in reducing power of the liver and kidney cell cytoplasm.

摘要

在兔血液中碳酸浓度增加的条件下(实验组),机体对注入的氨氮的利用增强,同时血液中酮酸水平以及肝组织中游离氨基酸和尿素水平升高。与对照组动物相比,这些动物血液和肝组织中谷氨酰胺含量降低;肝组织中α-戊二酸和谷氨酸水平升高,丙酮酸水平降低。肝和肾细胞质的还原能力也增强。
