摘要
用Ｋａｒｎｏｖｓｋｙ－Ｒｏｏｔ法，观察到胎儿胃食管角肌间丛、粘膜下丛、上皮下丛内有丰富的乙酚胆碱酯酶（ＡｃｈＥ）阳性神经。肌间丛和粘膜下丛内有深染的大型多极形、卵圆形ＡｃｈＥ阳性神经元，数量少，布于丛的周缘；也有染色浅的中小型圆形ＡｃｈＥ阳性神经元在丛内密集分布。本文还与胃食管角邻近的食管壁内的神经形态作比较。
By means of Karnovsky-Root’s histochemical method,acetylcholinesterase(AchE)positive nerves were foundto be abundant in intermuscular plexus,submucosal plexus and epithelial plexus in the wall of angle of stomach-esophagusThe fibers of AchE positive nerves in the intermuscular plexus and intermuscular nerves were especially concenlrated anddeeply stained.The AchE postive nerve branches in submucous layer innervated around blood-vessels and glands In sidethe muscles of mucosa,the nerve fibers were seen to form networks.The fibers of subepithelial nerve extended to epithelialcells.The large deeply coloured multipolar or oval form AchE Dositive neurons were seen around the intermuscular andsubmucoal plexus,and small and medium AchE positive neurons were seen crowded in the plexus.In this article,themorphology of the nerves in the wall of esophagus adjacent to the angle have also been studied in comparison.
