Abstract
Consistent consumption of high salt diet (HSD) has been associated with increased cellular generation of free radicals which has been implicated in the derangement of some vital organs and etiology of cardiovascular disorders. This study was designed to investigate the combined effect of some commonly employed medicinal plants on serum lipid profile and antioxidant status of aorta, kidney, and liver of high salt diet-fed animals. Thirty-five male Wistar rats were divided into 5 groups of 7 animals each. Group 1 and 2 animals were fed normal rat and 16 % high salt diet only respectively. Animals in groups 3, 4, and 5 were fed 16% high salt diet with 800, 400, and 200 mg/kg bw poly-herbal extract (PHE) respectively once for 28 consecutive days. Serum low-density lipoprotein (LDL), triacylglycerol (TG), total cholesterol (TC) and high-density lipoprotein (HDL), malondialdehyde, nitric oxide, catalase, superoxide dismutase, glutathione peroxidase, glutathione concentration, and activities were assessed in the aorta, kidney, and liver. PHE (p < 0.05) significantly reduced malondialdehyde and nitric oxide concentration and increased antioxidant enzymes and glutathione activity. Elevated serum TG, TC, LDL, and TC content in HSD-fed animals were significantly (p < 0.05) reduced to normal in PHE-treated rats while HDL was significantly elevated (p < 0.05) in a concentration-dependent manner in PHE treated animals. Feeding with PHE attenuated high salt diet imposed derangement in serum lipid profile and antioxidant status in the organs of the experimental rats.
