Alterations of il-1 and VEGF after ischemia-reperfusion injured uterus and ovary in rats, İskemi/reperfüzyon hasarı sonrası sıçanların over ve uterusunda il-1 ve VEGF değişiklikleri

Abstract

Objective: Ischemia/reperfusion injury causes parenchymal and endothelial cell damage as a result of inflammation. Vascular endothelial growth factor (VEGF) expressed in every kind of tissue in human body has important roles in migration, proliferation, endothelial cell perme-ability, angiogenesis and vasculogenesis. IL-1 is a one of the cytokine family members, and plays important roles in hematopoiesis, inflammatory reactions and immune system regulation. Furthermore, auto-inflammatory diseases are treated by IL-1 as therapeutic agent. The aim of this study is to observe changes of VEGF and IL-1 immunreactivity in ischemia/reperfused rat uterus and ovary. Method: Rats were separated into two groups. Control group and ischemia/reperfusion group which rats were subjected to 45 min ischemia/45 min reperfusion. Samples from uterus and ovary were fixed with 10% neutral formaldehyde and stained with H&E. VEGF and IL-1 immu-nohistochemistry was applied. Results: Histopathological results showed severe degeneration of endometrium in uterus and ovarian follicles in ischemia/reperfusion group. VEGF and IL-1 immunoreactivity increased in uteruses and ovaries of ischemia/reperfusion group when compared to control group Conclusion: In consequence, the present results suggest that VEGF and IL-1 may be potential detection marker for ischemia/reperfusion injured uterus and ovary. Moreover, VEGF and IL-1 might be in relation with each other to regenerate uterus and ovary. © 2021 Elsevier B.V., All rights reserved.
