THE IMMUNOHISTOCHEMICAL STUDY ON ?-EP,5-HT,5-HTR CELLS IN PANCREATIC ISLETS OF RATS DURING EXPERIMENTAL GASTRIC ULCER / 解剖学报

ABSTRACT

Objective Studies on the changes of ? EP, 5-HT, 5-HTR immunoreactive cells in pancreatic islets during experimental gastric ulcer. Methods The immunohistochemical technique was used. Results The numerical densities on area of ? EP, 5-HT, 5-HTR cells in experimental gastric ulcer group were higher than control group on the 4day,10day after operation.The peak of the numerical densities on area of ? EP and 5-HT cells appeared on the 4th day, while the peak of 5-HTR cells as on the 10th day. Part of ? EP, 5-HT,5-HTR immunoreactive material were located in A or B cells neighbourly section. Conclusion The present work proved that the ? EP, 5-HT,5-HTR cells of pancreatic islets were directly or indirectly participated in the regulation balance of endocrine during the self-healing process of the experimental gastric ulcer and here we provided morphological evidence.;
