The concentrations of gamma-aminobutyric acid (GABA), the activities of L-glutamate decarboxylase and GABA-transaminase, and the nature of the sodium-independent binding of GABA were examined in uterine tissue pieces obtained surgically from pregnant and non-pregnant women. GABA concentrations were reduced, while the activity of GABA-transaminase and the specific binding of [3H]GABA significantly increased in specimens from pregnant subjects. These findings suggest some gestation-related functional role for the GABA system in the human uterus.
对从孕妇和非孕妇手术获取的子宫组织块中γ-氨基丁酸（GABA）的浓度、L-谷氨酸脱羧酶和GABA转氨酶的活性以及GABA非钠依赖性结合的性质进行了检测。孕妇标本中GABA浓度降低，而GABA转氨酶活性和[3H]GABA的特异性结合显著增加。这些发现提示GABA系统在人类子宫中具有一些与妊娠相关的功能作用。
