The Effect of Acon on the Serum and Liver of Rats

The antioxidant effects of freeze-drying acorn were examined to find how much the freeze-drying acorn can reduce peroxidized corn oil poisoning, which influenced cholesterol, triglyceride, phospholipids, lipidperoxides, GOT(glutamate oxaloacetate transaminase), GPT(glutamate pyruvate transaminase) in serum, and cholesterol, triglyceride, lipidperoxides, fatty acid of phospholipids, SOD(superoxide dismutase), catalase in liver. In this experiment, male rats of Sprague-Dawley strain were used. The rats were divided into 6 groups, which were fed differently for 5 weeks : basal diet, 10% peroxidized corn oil added to basal diet, 1% acorn flour and 10% peroxidized corn oil added to basal diet, 5% acorn flour and 10% peroxidized corn oil added to basal diet, 10% acorn flour and 10% peroxidized corn oil added to basal diet, and 0.25% tannic acid and 10% peroxidized corn oil added to basal diet. The results were as follows : It was found that the peroxidized corn oil-fed rats for 5 weeks induced the elevation of cholesterol, triglycerides, lipid peroxides, GOT, GPT in serum, and cholesterol, triglycerides, lipid peroxides in liver as compared to the basal diet-fed rats, but the acorn flour-fed rats reduced the elevation of these components. In addition, saturated fatty acids in rat liver phospholipids induced the elevation by feeding of peroxidized corn oil and, on the other hand, the acorn flour-fed rats reduced the elevation of saturated fatty acids. The acorn flour-fed rats reduced the activity of SOD in liver while they enhanced the activity of catalase in liver as compared with the peroxidized corn oil-fed rats.
