直肠壁环行肌发达。
方法：用四道记录仪记录胃窦环行肌条的自发性收缩活动；
METHODS: Spontaneous contraction of gastric antral circular muscle of rats was recorded by four channel physiograph.
阿托品、维拉·帕米和六烃季胺部分阻断大黄对豚鼠胃窦环行肌条的兴奋作用。
Atropine, verapamil and hexamethonium partly blocked the increased action of rhubarb on the isolated strips of gastric antrum in guinea pigs.
结果表明：生长抑素对大鼠离体胃平滑肌条的兴奋作用局限在胃窦环行肌区域带。
These results indicate that the excitatory effect of somatostatin on gastric strips only locates in the antral circular smooth muscle in rats.
结论大黄对豚鼠胃窦环行肌条的收缩活动有兴奋作用。 大黄的这一兴奋作用部分经由胆碱能M受体、胆碱能N受体和L-型钙通道介导。
CONCLUSION Rhubarb has exciting actions on isolated antral circular strips of guinea pig, which is partly mediated via cholinergic M receptor, cholinergic N receptor and L-type calcium channel.
三种形式的生长抑素均兴奋大鼠胃窦环行肌条的活动，使其收缩波平均振幅增大，而对胃底、胃体和幽门等部位肌条的活动均无明显的影响。
Three molecular forms of somatostatin stimulated contractile activity of antral circular strips increasing the mean contractile amplitude, but failed to influence fundus, body and pylorus in rats.
为探讨非肾上腺素能非胆碱能神经递质对胃窦环行肌功能的调节作用，在离体胃平滑肌上观察了嘌呤拟似物对胃窦环行肌自发性收缩活动和电活动的影响。
Objective: to observe the effects of water extracts of Pericarpium Arecae on contraction of isolated circular muscle strips of gastric body in guinea pigs and to explore its possible mechanisms.
