inhibitory neurotransmitter

γ-amino butyric acid ( GABA), a well-studied inhibitory neurotransmitter, is involved in lots of metabolic activities.

γ-氨基丁酸（GABA）是目前研究较为深入的一种重要的抑制性神经递质，它参与多种代谢活动，具有很高的生理活性。

The results suggest that injection of adenosine into the renal artery activates ARNA via adenosine receptors in anesthetized rabbits and that nitric oxide may be involved in regulating the activity of renal sensory nerve fibers as an inhibitory neurotransmitter.

以上结果提示，肾动脉内应用腺苷可兴奋肾传入纤维的自发放电活动，一氧化氮作为抑制性因素参与腺苷诱导的肾神经传入纤维兴奋。

At the same time NO is known to function as an inhibitory neurotransmitter regulating the activity of renal afferent arteriole in rats.

同时，NO可作为一种抑制性神经递质参与肾入球小动脉活动的调节。
