Background: The ovarian Ischemia/reperfusion is one of the gynecological emergency concerns that may lead to the ovary damage and folliculogenesis. The present research aimed to evaluate the impact of the Chrysin (CH) on the ischemia-reperfusion (I/R) injury in the rat model.
Materials and methods: In this experimental research, 48 adult female rats, 8 weeks age and 180-200 g weight, have been categorized into 6 equal groups (n=8) including one sham and 5 ovarian torsion groups (OT+CH groups) that received different treatments. Each group has been treated 30 min before detorsion with gavage of CH or normal saline for 1 week and pregnant mare serum gonadotropin (PMSG) has been injected on the day 5 for initiating folliculogenesis. Finally, bio-chemical, molecular, histopathological, apoptotic and hormonal evaluations were performed.
Results: The anti-oxidant enzyme, superoxide dismutase and glutathione peroxidase, ameliorated in the ovarian tissues of the OT+CH groups in comparison with the OT group (P<0.001). Moreover, the level of serum Luteinizing hormone considerably declined and estradiol level (P<0.001), partly enhanced in the rats treated with CH in comparison with the ones in the OT group (P<0.05). In addition, histopathological scores of the OT+CH groups ameliorated in comparison with the OT group scores (P<0.05). Furthermore, the expression Caspase-3 and Bax genes were significantly increased while the expression of Bcl-2 was notably decreased in the OT group in comparison with the sham group (P<0.05).
Conclusion: Here, it seems that CH is possibly beneficial for the protection of ovaries against reperfusion injury and ischemia.
