The localization of G cell in the digestive tract in five kinds of marine fish
五种海洋鱼类消化道G细胞的定位

By using the gastrin antiserum and the immunohistochemical method of Streotavidin-Peroxid(S-P),the investigation on the distributions of G cells in the digestive tract of Bostrichthys sinensis,Sparus latus,Paralichthys olivaceus,Sigauns fuscesens and Boleophthalmus pectinirostris was made.The distributions of the G cells are as follows: In Bostrichthys sinensis,the G cells are mainly located in intestine,rarely in rectum;In Sparus latus,the G cells were only observed in intestine,none in any other parts of the digestive tract;In Paralichthys olivaceus,the G cells were observed numerously in stamachus pyloricus and intestine;In Sigauns fuscesens,the G cells were distributed in pyloric caecum and intestine;In Boleophthalmus pectinirostris,the G cells were observed in stomachus carsiacus,stamachus pyloricus and intestine,mainly located in stamachus pyloricus.The G cells were detected mainly in the stomach and intestine in 5 kinds of marine fish,the results show that the gastrin was correlated with function of digestion and absorption.The G cells were of polymorphism in 5 kinds of marine fish.It was suggested that the gastrin might exert the digestive physiology in different modes of endocrine.
