The endocrine cells in the digestive and glands of alligator sinensis embryos aged from 8th to 55th day were localized and compared by using immunohistochemical method with thirteen kinds of antiseras of hormone . during the development of pancreas in alligator sinensis embryos , somatostatin ( ss ) immunoreactive ( ir ) cells , 5 - hydroxytryptamine ( 5 - ht ) - ir cells , glucagon ( glu ) - ir cells , epidermal growth factor ( egf ) - ir cells appeared on 18th day . no p53 protein - ir cell , gastrin - ir cell , testosterone - ir cell , chromogranin a - ir cell , vasoactive intestinal polypeptide - ir cell , epithelial membrane antigen - ir cell or insulin - ir cell was found in the pancreas of alligator sinensis embryos 本实验采用免疫组织化学技术，应用13种不同的抗血清，对孵育时间8 ? 55天扬子鳄胚胎消化道及消化腺内分泌细胞的种类进行鉴别、定位和比较，结果如下：扬子鳄胚胎胰腺中，生长抑素、 5 ?羟色胺、胰高血糖素、表皮生长因子、胰多肽免疫反应阳性细胞出现于第8天； p物质免疫阳性细胞出现于第18天； p53 、胃泌素、睾酮、嗜铬素a 、血管活性肠肽、上皮膜肮原、胰岛素免疫阳性细胞在各期扬子鳄胚胎胰腺中均未发现。

Endocrine cells such as argyrophilic cells , 5 - hydroxytryptamine ( 5 - ht ) cells and gastrin cells were distributed in mucous and glandular epithelium of the digestive tract . the amount of endocrine cells was most in the glandular epithelium of stomach and was more in small intestine than that of large intestine and esophagus 消化道粘膜上皮和腺上皮分布着嗜银细胞、 5 - ht细胞和胃泌素细胞等内分泌细胞，其中以胃腺上皮中数量最多，小肠次之，大肠和食管零星散布。

It has been studied on the mechanism of ci from the view of the interaction among semicircular canal , otolith organ and proprioceptor . but the studies on neurophysiology mechanism are not enough . some scholars think that a great number of 5 - hydroxytryptamine ( 5 - ht ) accumulating in nerve center , which induced by protein disturbance of metabolism resulting from acceleration stimulation , resulted in vestibular illusions 对于科里奥利错觉的发生机制，目前仅从半规管、耳石器、躯体本体感受器相互作用角度进行了探讨，缺乏对其中枢生理机制的研究，有学者认为，加速度作用造成的蛋白质代谢障碍，引起5 -羟色胺在中枢的大量堆积，是造成前庭性错觉的主要原因。
