Potential protective effect of astaxanthin on ovary ischemia-reperfusion injury.

Objectives: We thought that astaxanthin (ASX) might be a protective agent in oxidative stress damage that develops against ischemia and reperfusion injury in the rat ovary. Materials and Methods: The experimental groups consisted of healthy, I (Ischemia), I+ASX50, I+ASX100, I/R (Ischemia/Reperfusion), I/R+ ASX50, and I/R+ ASX100. Vascular clamps were applied to the ovaries for 3 hr to induce ischemia. For the reperfusion groups, the clamps were opened and blood flow was restored to the ovaries for 3 hr. At the end of the experiment, biochemical, histopathological, and immunohistochemical analyses were made from the tissue samples taken. Results: While MDA levels increased significantly in I and I/R groups, SOD levels decreased. It was found that ASX significantly decreased MDA levels and increased SOD activity in treatment groups depending on the dose. Caspase 3, IL-1 β, and IL-6 expressions were severely increased in ischemia and I/R groups, while the severity of I+ASX50 and I/R+ASX100 immunoreactivity was decreased. While severe hemorrhage areas were observed in I and IR groups, minimal hemorrhage areas were observed in the treatment groups, especially in I/R+ASX100 groups. In addition, inflammatory cells and necrotic cells in the I/R group were not observed in I/R+ASX50 and I/R+ASX100 groups. Conclusion: As a result, it was determined that ASX has a strong protective role against oxidative damage in the treatment of ovarian ischemia-reperfusion injury.
