IMMUNOHISTOCHEMICAL STUDIES OF G-CELL AND D-CELL CHANGES IN THE ANTRAL MUCOSA OF RATS DURING EXPERIMENTAL GASTRIC ULCER / 解剖学报

ABSTRACT

53 male Wistar rats were divided into three groups, i.e. experimental ulcer group, saline control group and normal control group. The antral tissues were prepared for immunohistochemical staining at 4th, 10th, 14th, 21st and 28th days after operation. Sternberger's PAP method was used to demonstrate the gastrin cells (G cells) and somatostatin cells (D cells)in the antral mucosa in order to observe their changes during experimental gastric ulcer. The morphological relationships of G cells and D cells were examined by simultaneous double immunostaining method.The results indicated that the G cells count as well as D cells count in the antral mucosa was increased (P
