摘      要：AIM To identify the type localization andmorphology of APUD endocrine cells in thegastroenteropancreatic(GEP)system ofstomach-containing teleosts,and study APUDendocrine system in the stomach,intestine andpancreas of fish *** Two kinds of immunocytochemical(ICC)techniques of the streptavidin biotin-peroxidase complex(SABC)and streptavidin-peroxidase(S-P)method were ***,localization and morphology ofAPUD endocrine cells scattered in the mucosa ofdigestive tract,intermuscular nerve plexus andglandular body of northern snakehead(Channaargus),ricefield eel(Monopterus albus),yellow catfish(Pelteobagrus fulvidraco),mandarinfish(Siniperca chuatsi),largemouthbass(Micropterus salmoides),orientalsheatfish(Silurus asotus),freshwater pomfret(Colossoma brachypomum)and nile tilapia(Tilapia nilotica)were investigated with 8 kindsof *** The positive reaction of 5-hydroxytryptamine(5-HT)immunoreactiveendocrine(IRE)cells was found in the digestive tract and glandular body of 8 fish species indifferent *** a few gastrin(GAS)-IREcells were seen in ***,*** and ***(GLU)-IRE cells were notfound in the digestive tract and glandular bodybut existed in pancreatic island of most *** positive reaction of growthhormone(GH)-IRE cells was found only inpancreatic island of *** and ***,no positive reaction in the other 6 fish ***(SOM)-,calcitonin(CAL)-,neurofilament(NF)-and insulin(INS)-IRE cellsin the stomach,intestine and pancreas of 8 kindsof fish were different in distribution and *** distribution of all 8 APUD cells was the mostin gastrointestinal epithelium mucosa and then indigestive *** positive reaction of SOM-and 5-HT-IRE cells was found in intermuscularnerve plexus of intestine of *** *** GH-IRE cells were denselyscattered in the pancreatic islands of *** ***,and odd distribution in thepancreas of ***,SOM-IRE cells we
