Effects of iloprost on experimental ischemia and reperfusion injury in rat ovary

We investigated the protective effect of iloprost against ischemia/reperfusion (I/R) injury in rat ovary. We used 32 female Sprague-Dawley rats randomly allocated to four experimental groups: sham, ischemia, I/R and I/R + iloprost. Ovarian torsion was established in all rats except the sham group. The torsion group was exposed to ischemia for 3 h. The detorsion group was exposed to 3 h ischemia applied + 3 h reperfusion. The detorsion + iloprost group was exposed to ischemia for 3 h + reperfusion for 3 h + intravenous (IV) iloprost infusion for 60 min starting at the beginning of reperfusion. Ovaries were removed and prepared for histopathological evaluation. Reduced glutathione (GSH) and malondialdehyde (MDA) were measured in the blood. The total histopathological injury score and MDA level of the ischemia group were significantly higher than for the sham group. Ovarian injury score and MDA level following I/R increased compared to the ischemia group. Iloprost administration reduced the total injury score and MDA level. The GSH level was higher in the I/R + iloprost group than in the I/R group. We concluded that IV iloprost administration reduces I/R injury in rat ovarian tissue.
