Introduction: Triclosan [TCS] is a broad-spectrum antibacterial xenoestrogen commonly used in cosmetics, soap and various products. Exposure to Triclosan creates a disruption between reactive oxygen species (ROS) and antioxidant defenses. Oxymatrine [OMT] has potent anti-cancer, anti- , and anti-oxidant effects. Aim of work: To study the effect of Oxymatrine on Triclosan-induced ovarian toxicity. Material and Methods: The studied rats have been divided into groups for measurement of total antioxidant capacity, Caspase-3, the levels of Tumor Necrosis Factor –alpha[TNF- ], Estrogen and Progesterone levels , and Liposaccharide Binding Protein [LBP] gene expression in response to Triclosan-induced ovarian toxicity by realtime Polymerase Chain Reaction [PCR]. Results: Triclolsan [TCS] caused statistically reduction in total antioxidant capacity, with statistically elevation in TNF- and Caspase-3 activity compared to the control group. Oxymatrine induced statistically elevation in total antioxidant capacity, statistically decrease in the level of TNF- , Caspase-3 activity with increased levels of Estrogen and Progesterone compared to the Triclosan group. Histopathological and electron microscope examination revealed vacuolar degeneration and atretic follicles in rats treated with Triclosan, and improvement after Oxymatrine intake. In the Triclolsan + Oxymatrine [TCS+OMT] group, gene expression levels of TNF- , Caspase 3, Mitogen-activated protein kinase [MAPK], Nuclear Factor-kappa [NF-KB], and Liposaccharide Binding Protein [LBP] were statistically reduced compared to the Triclolsan group. Conclusion: The use of Oxymatrine [OMT] as anti-oxidant lead to decrease in genetic expression of Tumor Necrosis Factor –alpha [TNF- ] , Caspase 3, p38 MAPK, [NF-KB], and LBP, in Triclosan-induced ovarian injuries.
