神经递质和其他化学介质对胆道系统调节的研究较为深入,本文仅就其几个方面作一简介。 乙酰胆碱和胆碱能神经 胆碱能神经分布于胆小管、胆管、胆总管及胆囊。用乙酰胆碱酯酶(Ach E)活性组织化学法证实,胆道系统壁内存在胆碱能神经。在人胆囊粘膜、上皮和基底膜不存在Ach E活性阳性神经纤维,但在固有层有Ach E阳性神经纤维。 乙酰胆碱(Ach)或胆碱能神经在不同程度上参与胆道运动和胆汁分泌的调节。
Neurotransmitters and other chemical mediators on the regulation of the biliary system more in-depth, this article only on a few aspects of a brief introduction. Acetylcholine and cholinergic nerve cholinergic nerve distribution in the bile duct, bile duct, common bile duct and gallbladder. Using acetylcholinesterase (AchE) activity histochemistry confirmed cholinergic nerve in the biliary system wall. In the human gallbladder mucosa, epithelial and basal membrane does not exist Ach E active positive nerve fibers, but in the lamina propria Ach E positive nerve fibers. Acetylcholine (Ach) or cholinergic nerves are involved in the regulation of biliary tract motility and bile secretion to varying degrees.
