cAMP和cGMP是细胞内代谢的重要调节物质,最近10多年现代医学生物学领域内研究比较集中的指标之一。根据我们对苦甘草硷药理作用的研究证明,在整体动物试验,它有明显的平喘作用,且比氨茶硷强。在离体豚鼠气管实验,证明也有松弛气管平滑肌的作用,但需高浓度,而且较氨茶硷弱。此扩张气管平滑肌的作用,可被β受体阻断药心得安所阻 cAMP and cGMP are important regulators of intracellular metabolism and have been one of the most concentrated indicators in the field of modern medical biology in the past 10 years. According to our research on the pharmacological effects of Bitter Glycyrrhiza, it has obvious anti-asthmatic effect in the overall animal test, and it is stronger than ammonia tea. In isolated guinea pig trachea experiments, it was also shown that there is relaxation of the tracheal smooth muscle, but the need for high concentrations, and weaker than ammonia. This expansion of the role of tracheal smooth muscle can be blocked by β-adrenergic blockade
