The Effects Of Chard On Brain Damage In Valproic Acid-Induced Toxicity

Valproic acid (VPA; 2-propyl valeric acid) is a potent drug widely used in treating anxiety disorders, migraine as well as epileptic diseases. In the ongoing study chard protective effect was investigated, on the damaged VPA rat brain. Sprague Dawley rats (females) were grouped as follows: control, VPA (500 mg kg(-1) day(-1)VPA intraperitoneal), chard (100 mg/kg day chard extract by gavage), VPA + chard (500 mg kg(-1) day(-1)VPA + 100 mg kg(-1) day(-1)chard extract). Aqueous chard leaves extract was given 1 hr before apply VPA for a period of 7 days. Lipid peroxidation, advanced oxidation protein products and protein carbonyl content, and superoxide dismutase, glutathione peroxidase, glutathione-S-transferase, and glutathione reductase activities increased in the VPA group. Reduced glutathione levels, paraoxanase, and acetylcholinesterase activities were significantly diminished in the VPA animals. Chard extract application curatively reverted the studied biochemical parameters. The results obtained, it has been found the chard has a protective and antioxidant effect on brain damage induced by VPA. Practical applications Valproic acid is a comparably safe pharmaceutical agent, but it can cause severe adverse effects on biological metabolism when it is used in high amount. There are not many studies declared that VPA stimulate the generation of ROS, which is liable for the life-threatening adverse effects of VPA therapy including hepatotoxicity neurotoxicity and teratogenicity. Chard is a plant which has antimicrobial, antibacterial, antiinflammatory, antioxidant, antitumor, antiacetylcholinesterase activities, and hepatoprotective effects. In the current study we examined the protection of the VPA damaged rat brain by chard.
