| Abstract | ||||
| Introduction: The present study deals with the effect of oat bran (Avena sativa L.) in the treatment of hypercholesterolemia in comparison with a hypocholesterolemic drug, atorvastatin, on hypercholesterolemic liver in male albino rats. Material and Methods: For this purpose four groups of rats (each containing 6 rats) were used. The first group was used as a control, the second was cholesterol-fed group with cholesterol (0.5% w/w) for 6 weeks. The third group was oats-fed hypercholesterolemic rats on oat supplemented diet (20% w/w) for 4 weeks and the forth group was atorvastatin-treated hypercholesterolemic rats orally at a dose of 0.18 mg/Kg body weight/day for 4 weeks. Results: The biochemical results revealed a significant increase in serum LDL-C and a significant decrease in HDL-C level. In addition the activity of AST was increased in cholesterol-fed rats. Meanwhile, the treatment with oat soluble fiber or atorvastatin drug improved the above mentioned parameters. The histopathological examination of liver sections of cholesterol-fed group showed accumulation of lipid. Hepatocytes showed ballooning degeneration and manifested clear necrotic signs. Inflammatory cellular infiltration was found around the blood vessels, mild fibrosis near the portal blood vessels. However, liver impairment was reduced markedly in the liver of oat soluble fiber fed rats rather than atorvastatin drug treated rats. Conclusion: The present study, however, confirms that the cereal grain oat may have potent beneficial health effects in reducing LDL cholesterol and should be included in the prudent diet of individuals with hyperlipidemia. | ||||
