AIM: This study is a biochemical investigation of the effect of etoricoxib, a selective cyclooxygenase (COX)-2 inhibitor, on ischemia/reperfusion (I/R) injury experimentally induced in rat ovaries. METHODS: Experimental animals were divided into four groups: (i) ovarian ischemia/reperfusion (IRG); (ii) 30 mg/kg etoricoxib + ovarian ischemia/reperfusion (EIRG-30); (iii) 60 mg/kg etoricoxib + ovarian ischemia/reperfusion (EIRG-60); and (iv) a sham operation (SG) control group. RESULTS: The results showed levels of malondialdehyde in the IRG, EIRG-30, EIRG-60 and SG group ovarian tissue of 20.2 ± 3.4, 11.2 ± 3.2, 5.5 ± 1.9 and 3.8 ± 1.5 μmol/g protein, respectively. Myeloperoxidase activity for these groups was 24.2 ± 6.7, 13 ± 2.4, 4 ± 1.8 and 3.5 ± 1.9 U/g protein, and total glutathione levels were 1.6 ± 0.8, 4.5 ± 1.9, 6.5 ± 1.9 and 7.5 ± 2.4 nmol/g protein, respectively. COX-1 activity in IRG, EIRG-30, EIRG-60 and SG group rat ovarian tissue was 5.0 ± 2.8, 12.2 ± 2.4, 16.7 ± 2.8 and 17.5 ± 4.7 U/mg protein, and COX-2 activity was 18.3 ± 2.7, 3.5 ± 1, 1.8 ± 0.7 and 0.7 ± 0.3 U/mg protein, respectively. CONCLUSION: Etoricoxib prevented oxidative damage induced with I/R in rat ovarian tissue. This property of etoricoxib suggests that it can be clinically beneficial in the prevention of damage that may arise with reperfusion by detorsion for the protection of the ovaries against torsion.
