curcumin and Ovarian-Diseases

To evaluate the protective effects of curcumin in experimental ischemia and ischemia/reperfusion (I/R) injury of rat ovaries.. Forty-eight female adult Wistar Albino rats were used. Rats divided into six groups and designed: Sham, Torsion, Detorsion, Sham + Curcumin, Torsion + Curcumin, and Detorsion + Curcumin. Except for the Sham and Sham + Curcumin group, all groups were performed to bilateral adnexal torsion for 3 h. Bilateral adnexal detorsion was implemented in the Detorsion and Detorsion + Curcumin groups. The injection of curcumin was intraperitoneally achieved 30 min before the sham, torsion and detorsion.. Total oxidant status levels (TOS), oxidative stress index (OSI) and histologic scores values of ovarian tissue were higher in the torsion and detorsion groups than the sham group (p < 0.05). There was a strong correlation between the total histologic scores of I/R injury and the OSI (r = 0.809, p < 0.001). By the use of curcumin, a significant decrease was established in the mean levels of oxidant markers and histopathologic scores of the ovarian tissues.. Administration of curcumin is effective in reversing tissue damage induced by ischemia-reperfusion injury in ovarian torsion.

In experiments on CBA mice, we studied the influence of an inhibitor of nuclear transcription factor kappaB activation curcumin, obtained from Curcuma longa, on the meiotic maturation of oocytes and apoptotic and necrotic death of follicular cells at immune ovary failure induced by immunization of animals with allogenic ovarian extracts. NF-kappaB plays a pivotal role in the induction of genes encoding pro-inflammatory factors (cytokines, adhesion molecules, inducible NO-synthase and cyclooxygenase) and in regulation of cell proliferation and death. It has been shown that immunization of mice increased the death of follicular cells through anapoptotic and necrotic pathways, which led to inflammatory response (according to blood leukogram and impairment the oocyte meiotic maturation at metaphase I and II). Intragastric administration of curcumin (Sigma, USA, 2 mg of the mouse weight, four times a week during the period of immunization) reduced the number of the follicular cells died through apoptotic and especially necrotic pathway. Curcumin attenuated an inflammatory response and improved the meiotic maturation of oocytes impaired under experimental immune ovarian failure in mice.
