The regional distributions and frequencies of argentaffin endocrine cells in gastrointestinal (GI) tract of osteoporotic Sprague-Dawley rat induced by ovariectomy were studied by Masson-Hamperl silver stain. The experimental animals were divided into two groups, one is non-ovariectomized group (Sham) and the other is ovariectomized group (OVX). Samples were collected from each part of GI tract (fundus, pylorus, duodenum, jejunum, ileum, cecum, colon and rectum) at 10th week after ovariectomy or sham operation. Argentaffin cells were detected throughout the entire GI tract with various frequencies regardless of ovariectomy except for the rectum of OVX in which no cells were detected.
