    Abstract:
    OBJECTIVE: To investigate the changes of gastrin, somatostatin and motilin production in the gastric antral mucosa of rats with experimental gastric ulcer. METHODS: Rat models of gastric ulcer model were induced successfully by injection of acetic acid into the gastric antral wall of 2 groups of Wistar rats (7 in each group) that were subjected to environment of either high or normal temperature. Another 2 groups of rats (n=7) receiving normal saline injection in the same manner, along with still another 2 groups (n=7) without any treatment, all of which were kept under conditions with different temperatures accordingly, constituted the control groups. The levels of gastrin, somatostatin and motilin in the gastric antral mucosa of the rats were measured with radioimmunoassay. RESULTS: In rats with gastric ulcer, the levels of gastrin and motilin in the antral mucosa increased, but in a lesser scale in rats with ulcer kept in high temperature than in normal temperature group, while that of somatostatin was reduced. The level of somatostatin declined less in the high temperature group with ulcer than in the normal temperature group with ulcer. CONCLUSION: High temperature can affect gastrin, somatostatin and motilin production in the gastric antral mucosa of rats with gastric ulcer.
