摘要

目的:探讨桂枝汤有效部位B（Fr.B）对胃肠运动双向调节的作用机理。方法:应用放射免疫法测定阿托品致胃肠运动受抑或新斯的明致胃肠运动亢进大鼠下丘脑及胃肠组织cAMP含量、PKA和PKC活性。结果:对阿托品致胃肠运动受抑大鼠

Fr.B可拮抗下丘脑和空肠组织cAMP含量及PKA、PKC活性的降低

对胃窦组织PKA活性的降低也具拮抗作用;对新斯的明致胃肠运动亢进大鼠

Fr.B可升高胃窦组织PKA活性、下丘脑和空肠组织PKC活性

对cAMP含量无明显影响。结论:Fr.B对胃肠运动的双向调节与其影响下丘脑及胃肠局部组织中cAMP含量和蛋白激酶活性有关。

Abstract

Objective:To investigate the effective mechanism of dual-direction regulation of Fr.B

an active fraction extracted from Guizhi Tang（GZT）.on gastrointestinal motility.Methods:The cAMP content

protein kinase A（PKA）and C（PKC）activity of hypothalamus and gastrointestinal tissues in rats with excited or inhibited gastrointestinal motility induced respectively by neostigmine or atropine were measured via radioimmunoassay.Results:Fr.B increased the cAMP content and PKA and PKC activity of hypothalamus and jejunum in rats with inhibited gastrointestinal motility significantly

and antagonized the decrease of PKA activity of gastric antrum.In rats with excited gastrointestinal motility

Fr.B increased PKA activity of gastric antrum

PKC activity of hypothalamus and jejunum

and did not affect the cAMP content.Conclusion:Fr.B could affect the cAMP content

PKA and C activity in hypothalamus and gastrointestinal tissues to regulate gastrointestinal motility in a dual-direction manner.
