【摘要】 新生儿胃的神经支配通过三种方法进行了研究:(1)乙酰胆碱酯酶活性的测定;(2)乙醛酸诱发荧光;(3)Cajal-Faworsky神经染色。胆碱能神经在粘膜下层有大量的神经干和神经纤维交织组成丛,一些穿过粘膜肌层终止在腺细胞,神经节较少。在肌层间有大量神经节和神经丛。肾上腺素能神经在粘膜下层和肌层常攀附小动脉壁,在动脉中、外膜之间形成丛。且肾上腺素能神经和胆碱能神经同时分布到胃壁的平滑肌和粘膜腺。本文并对胃壁内的神经节进行了讨论。更多还原

【Abstract】 The intrinsic innervation of neonate gastric wall was studied by means of (1) demostration of the acetylcholinesterase activity, (2) fluorescence microscope and (3) the technique of silver impregnation, the cholinergic innervation was rich in submucosa where a large number of nerve trunks and nervous fibers were interlaced to form networks. Some branches can be tr- aced to nervous plexus of intermuscules and other penetrated mucosal muscle to terminate inglandular cells. A large quantity of ganglions and nervous plexus were located between muscular layers. In general, nerve was rich in the circular muscular layer. Most fibers of the nerve were parallelled to long axis of smooth muscular cell. Both artery and vein in submucosa were enclosed by adrenergic nerves that formed plexus between tunica adventitia tunica medium of the vessels. The fibers of adrenergic nerve between the fibers of the muscle also were parallelled to long axis of smooth muscle cell. The cholinergic and adrenergic nerves described above were also distributed to mucosal gland. Finally, the ganglion within gastric wall and their clinical implication were discussed.更多还原
