Abstract

The relative frequency and distribution of occurrence of immunoreactive cells in the proventriculus, diverticulum, cardia, fundus and pylorus of the stomach of pigs were investigated by PAP method using specific antisera against BCG, Gas/CCK, 5-HT, somatostatin, glucagon, BPP, motilin and insulin. In the diverticulum and cardia, BCG-, 5-HT-, somatostatin- and glucagon-immunoreactive cells were detected. In the fundus, BCG-, 5-HT- and somatostatin-immunoreactive cells were also found. In the pylorus, BCG-, Gas/CCK-, 5-HT-, somatostatin- and glucagon-immunoreactive cells were observed. However, no BPP-, motilin- and insulin-immunoreactive cells were found in the stomach epithelium of the pigs. These results showed that the occurrence of the endocrine cells confirmed in the diverticulum as the cardia and suggest that the function of diverticulum may be similar to that of cardia in the pigs.
