- Abstract
Objective Experimental and clinical studies suggest that oxidative stress plays an important role in the pathogenesis of multiple sclerosis. Multiple studies have shown that non-psychoactive cannabinoid, cannabidiol (CBD) exerts antioxidant effects, and has recently been approved for treatment of inflammation, pain, and spasticity associated with MS patients. The aim of this study is to determine the effectiveness of CBD in a multiple sclerosis mouse model, i.e. cuprizone-induced demyelination. Methods Adult male BL/6 mice were fed with 0.2% cuprizone for 5 weeks which caused severe demyelination of the corpus callosum (CC). Animals were simultaneously treated with 5 mg·kg-1 CBD by daily intra-peritoneal injections. Using immunohistochemistry and transmission electron microscope, we evaluated the effects of CBD on demyelination, malondialdehyde levels and the activity of reduced glutathione, catalase and superoxide dismutase was evaluated by Biochemical analysis. Results CBD ameliorate the cuprizone-induced demyelination and microglia accumulation. Biochemical analysis showed that oxidative stress induced by cuprizone was reduced by CBD. Conclusion Our data implicate that CBD attenuates destructive effects of cuprizone in the CC by decreasing oxidative stress and microglia repletion.
