Abstract

In this study, we examined the ultrastructural influence of radiation on rats stomach tissue, the difference between NPO and con in the rats stomach was measured after a single irradiation to 15 Gy dose, the results follow ; Widening of intercellular space, and swelling and degeneration of secretory granules in chief cells were observed from NPO rats of a day after irradiation. In mucosal epithelial cells of con rats of 7 days after irradiation, destruction of microvilli was similar to from NPO rats of a day after irradiation but morphology was cuboidal. Parietal cell proliferation and differentiation were active as well as mucous epithelia structures were stable like to control rats from con of 14 days after irradiation. But NPO rats were not until 28 days after irradiation that mucous epithelial structures were stable too. On the basis of this results, we know obviously that NPO will be a factor of stomach abnomalities while hospital patients are treated with high-energy irradiation.
