Effect of Ovariectomy Induced Hyperphagia on the Intestinal Adaptation

난소절제에 의해 유발된 과식현상이 소장적응변화에 미치는 영향

Ovariectomy induced hyperphagia was reported in various animal models. It was postulated that hyperphagia resulted in interstinal hypertrophy and hyperplasia. Therefore, this study was performed to compare the food intake and intestinal changes between ovariectomized rats(OVX) and sham operated rats(Sham). Results of this study showed that the food intake and body weight of OVX animal was significantly higher than those of Sham animal. This results confirmed the effect of ovarian hormone on the food intake regulation. Hyperphagia induced by ovariectomy influence the intestinal cell growth and showed hyperplasia determined by protein/DNA ratio. Maltase and alkaline phosphatase activity suggested that the intestinal cell was fully matured in body groups. There were no difference in weight of other organs, such as liver, heart and kindney between two groups.
