Effects of Melatonin on Ischemia-Reperfusion Injury in Rat Ovary: Histopathologic and Immunohistochemical Study
Aim: To investigate the effect of melatonin on ischemia–reperfusion (I/R) injury in rat ovary. Material and Method: A total of 24 Wistar rats were divided into four groups. The rats were first numbered randomly and then randomly divided into four equal groups: sham, torsion, detorsion and melatonin groups. In group I (n = 6) sham, as well as in group II ovary torsion was not performed and no drug was administered. In group III, 1 hour of ischemia and 2 hours of reperfusion were performed and no drug was given. In group IV, melatonin was dissolved in 1% ethanol just before use. Melatonin was injected 1 hour before torsion to the torsion plus melatonin group. Right ovaries were surgically removed in all groups. Result: Malondialdehyde (MDA) levels were measured. We suggested that administration of melatonin would be in treating ovaries from torsion/detorsion induced damage in humans. The histopathological changes such as vascular congestion, edema, hemorrhage, and follicular degeneration were found to be decreased in the melatonin + ischemia-reperfusion group. Ischemia-reperfusion group: PECAM-I expression is positive in vessel of the stromal area. The follicles and interfolicular area infiltrated with CD68 positive cells were increased in a time of ischemia-reperfusion exposure dependent manner. Conclusions: Melatonin after ischemia-reperfusion CD31 and CD68 expressions is weak, due to the reduction of the inflammatory effects and hemorrhage is thought that melatonin is effective.
