近年γ—氨基丁酸(GABA)系哺乳动物神经中枢主要抑制性递质的观点被广泛接受。作者根据对家兔暴发型肝衰模型的观察,以及已发现肠道菌落是血循中 GABA主要来源,提出 GABA 神经递质体系的失常并从而抑制神经系统正常功能活动,可能与肝性脑病的症状及发病有关。为证实以上推论,怍者用放射性氚标记 GABA 为 In recent years, γ-aminobutyric acid (GABA) is the main inhibitory neurotransmitter mammalian point of view is widely accepted. Based on the observation of the model of fulminant hepatic failure in rabbits and the fact that intestinal colonies have been found to be the main source of GABA in the bloodstream, the authors propose a disorder of the GABA neurotransmitter system and thereby inhibit the normal functional activity of the nervous system, possibly related to hepatic encephalopathy Symptoms and pathogenesis. To confirm the above inference, I use radioactive tritium labeled GABA as
