ABSTRACT
Noncommunicating uterine horns are rare, occasionally presenting with functional endometrial cavities, Surgical removal of the noncommunicating horn is commonly performed to prevent endometriosis and rupture of a pregnancy in these patient. We report a case of rudimentary horn with pelvic and appendicular endometriosis treated by laparoscopic resection of those lesions.

A putative polypeptide hormone identified as amylin[islet amyloid polypeptide] is synthesized and co-localized with insulin in B cells of pancreatic islets in several animal species including man. However, there is growing evidence that somatostatin cells are also expressed and contained amylin in the pancreatic islets of the rat The aim of the present study was to investigate the immunocytochemical expression of the amylin within the endocrine pancreas of the man, rabbit and guinea pig, with special reference to the possible ability of islet cells other than insulin cells to synthesize amylin. For this purpose serial sections of the pancreatic islets were stainedimmunocytochemically using anti-amylin, anti-insulin, anti-glucagon, anti-somatostatin antisera. In serial sections of pancreatic islets of the man and rabbit, it was shown that amylin immunoreactivity occurred in insulin-reactive B cells predominantly located in interior of the islets. In contrast, amylin immunoreacivity appeared in glucagon-reactive A cells peripherally located in the islets of the guinea pig. These results suggest that in both the man and rabbit, amylin is synthesized by B cells for subsequent co-secretion with insulin, and that in guinea pig, amylin is synthesized by A cells for co-secretion with glucagon. It thus appears that amylin release may be mediated by different secretory mechanisms according to animal species.
