为了给临床病理状态下胃溃疡神经分布提供参照，更好地为溃疡病的防治提供形态学依据，本文采用Ｋａｒｎｏｖｓｋｙ－Ｒｏｏｔｓ法，观察了４例正常人胃壁胆碱能神经纤维分布特点。结果：胃壁各层均有乙酰胆碱酯酶（ＡＣｈＥ）阳性纤维，但上皮和固有层上部未见ＡＣｈＥ阳性纤维；ＡＣｈＥ阳性纤维有４种形态：终末纤维、终末前纤维、神经束、神经干，胃壁各层细小动脉壁也存在神经末梢分布，在含非特异胆碱酸酶反应中，可见胃粘膜上皮下固有膜内，存在分支的神经末梢交互联成网状，可能是传入性质，对其功能意义做了讨论
In order to provide a reference for the distribution of gastric ulcer in the clinical pathological state, and to provide a better morphological basis for the prevention and treatment of ulcer disease, this paper used Karnovsky-Roots method to observe the distribution characteristics of gastric normal human cholinergic nerve fibers. RESULTS: AChE-positive fibers were found in all layers of the stomach wall but no AChE-positive fibers were seen in the upper layers of the epithelium and lamina propria. AChE-positive fibers were found in four forms: terminal fibers, terminal fibers, nerve bundles, , The small intestine wall of the stomach wall also exists the distribution of nerve endings, with non-specific cholinesterase reaction, visible in the gastric mucosa submucosal lamina propria, there are branches of the nerve endings interact into reticular, may be the incoming nature, The significance of its function is discussed
