Abstract

The central effects of carboxyethyl-gamma-aminobutyric acid (CEGABA) have been studied both in rabbits and in the guinea pig myoclonus model. This drug caused EEG synchronization and behavioural sedation both after intravenous (i.v.) and intracerebroventricular (i.c.v.) administration in a dose-dependent manner, in rabbits. CEGABA showed a protective action against myoclonus induced by means of L-5-HTP in young guinea pigs. These data substantiate the hypothesis that CEGABA is a drug active on the central nervous system and probably exerts its action by strengthening cortical inhibition and/or directly acting on lower brainstem.

羧乙基- γ -氨基丁酸(CEGABA)中枢效应的实验研究。
羧乙基- γ -氨基丁酸(CEGABA)的中枢作用已经在家兔和豚鼠肌阵缩模型中进行了研究。在家兔中,该药物在静脉注射(i.v.)和脑室注射(i.c.v.)后均以剂量依赖性方式引起脑电图同步和行为镇静。CEGABA对L-5-HTP诱导的幼年豚鼠肌阵缩有保护作用。这些数据证实了CEGABA是一种对中枢神经系统有活性的药物,可能通过加强皮质抑制和/或直接作用于脑干下部来发挥作用。
