#19 : Green Tea Extract Inhibits Endometriosis Progression by Increasing Superoxide Dismutase Serum Levels in the Rat Models

Abstract

Background and Aims: Endometriosis is a gynecological disorder defined as the presence of endometrial tissue outside the uterine cavity and affecting 10-15% of females of reproductive age. Oxidative stress has been reported as one of the main promoting factors of this disease. Green tea and its anti-angiogenic and antioxidant properties have promising potential to prevent the progression of endometriosis. This study aims to investigate the effect of green tea extract on endometriotic implant area and serum superoxide dismutase (SOD) levels in endometriosis rat models. Method: Twenty-six Balb/c female rats were randomized into two groups of equal size: experimental group (EG) and control group (CG). All subjects in EG were given green tea extract 3 mg daily for 14 days. Endometriosis was induced on the fourteenth day in all subjects in both groups. The data of the endometriotic implant area and serum SOD were obtained and analyzed fourteen days after the induction of endometriosis. Results: The endometriotic implant area of the group treated with green tea extract was significantly lower (p=0,022) RR=0,455, 95%CI=0.065-0,96) compared to the control group. The serum level of SOD in EG and CG were 5.33±0.52 ng/ml and 5.20±0.91 ng/ml, respectively (p=0.507). Conclusion: Green tea extract inhibits endometriotic implant progression and increases the level of serum SOD in endometriosis-induced rat models.
