Content and biosynthesis of glycogen in rat liver tissue as well as transition of 14C from main substrates of tricarboxylic acid cycle to CO2, examined in liver slices, were studied under conditions of stress caused by pain and emotion. The stress was accompanied by mobilization of the glycogen deposits; glycogen synthesis in liver tissue and oxidation of pyruvate, asparate succinate or alpha-ketoglutarate in tricarboxylic acid cycle were inhibited. At the same time, the stress was accompanied by ulcerous impairments of gastric mucosa. The phenomena observed appear to be due to increased activity of adrenergic and sympathoadrenal systems. Prior to the stress administration of sodium gamma-hydroxybutyrate, which activates the inhibitory GHB-ergic system of brain, prevented distinctly the impairments found.
在由疼痛和情绪引起的应激条件下,研究了大鼠肝脏组织中糖原的含量和生物合成,以及在肝切片中14C从三羧酸循环的主要底物向二氧化碳的转变。应激伴随着糖原储备的动员;肝脏组织中的糖原合成以及三羧酸循环中丙酮酸、天冬氨酸、琥珀酸或α-酮戊二酸的氧化受到抑制。同时,应激伴随着胃黏膜的溃疡性损伤。观察到的这些现象似乎是由于肾上腺素能和交感肾上腺系统活性增加所致。在施加应激之前给予γ-羟基丁酸钠,可激活大脑的抑制性γ-羟基丁酸能系统,明显预防了所发现的损伤。
