Researching serum and tissue level of ghrelin and obestatin in the cases histopathologically identified as endometriosis

Researching Serum And Tissue Level Of Ghrelin And Obestatin İn The Cases Histopathologically İdentified As EndometriosisEndometriosis is defined as having different localization apart from normal anatomic location and functional endometrial in uterus.Now that it was showed that ghrelin is found at GHS-R and ghrelin protein mRNA endometrium, this study was planned to research whether these peptides are expressed in ectopic endometrium of phenomenon identified as endometriosis, serum level and their possible role in endometriosis physiopathology.In this study we, histopathologically, investigated the serum levels of these cases, the ectopic and eutopic endometrium tissues of 30 cases diagnosed as endometriosis and 15 cases without pelvic pathology, together with the ELISA and immunohistochemistry methods in the eutopic endometrium tissues of ghrelin and obestatin.In the ectopic and eutopic endometriums of the tissues with endometriosis, it was shown that ghrelin and obestatin was expressed together with both of the methods in the eutopic endometriums of the control group cases and compared to the proliferative phase, the expression in the secretory phase was much higher in the comparision of these internal groups. A meaningful variance has not been detected in the tissue and serum levels of these two groups.Both in the eutopic and ectopic endometrium tissues of the patients with endometriosis, ghrelin and obestatin expression was detected. Therefore, these findings have revealed that the etiology of endometriosis will probably be normal endometrium and might shape a new direction to the definition of endometrium reseptivness in the further advanced studies.Key words: Endometrium, endometriosis, ghrelin, obestatin
