Protective effects of curcumin against valproic acid induced brain kidney and liver damage in rats.

Valproic acid (VPA) is a broad-spectrum drug that is now widely used as an antiepileptic. Although VPA has positive therapeutic effects, it also causes various toxic effects in tissues. Curcumin, a natural antioxidant found in ginger, has antibacterial and antiinflammatory activity. In this study, the toxic effects of VPA on brain, kidney, and liver tissues and the protective activity of curcumin against these effects were investigated. In this study, male Wistar-Albino rats were used. Rats were divided into 4 groups control, VPA, CUR, and CUR + VPA. Rats were administered intraperitoneal VPA and CUR intragastrically. In the study, MDA, SOD, IL-6, and IL-18 levels were measured by the ELISA method in rats. It was observed that VPA triggered oxidative stress and inflammation in tissues, while CUR administration positively regulated these parameters. Studies also showed that VPA increased the expressions of TNF-α and NF-kB in tissues, but CUR administration downregulated these expressions The findings revealed that CUR protects by preventing the oxidative stress and inflammation caused by VPA in the tissues and may be an important agent in reducing the side effects of this drug used as an antiepileptic.
