ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of Ganoderma lucidum polysaccharides on oxidative stress of hyperlipidemic fatty liver in rats.</p><p><b>METHOD</b>Seventy-two SD rats were randomly divided into six groups, namely the normal control group (NG), the model group (MG), the G. lucidum polysaccharides groups of low, middle and high dose (GLPs-LG, GLPs-MG, GLPs-HG) and the Simvastatin group (SV). The rats were fed with high fat diet to establish the model of hyperlipidemic fatty liver in rats. After administration for 12 weeks, rats in each group were tested with the following indexes total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and total antioxidant capacity (T-AOC) in serum as well as the contents of SOD, MDA, GSH-Px and T-AOC in hepatic tissues. Histopathological changes of hepatic tissues were observed under light glass.</p><p><b>RESULTS</b>The contents of TC, TG and LDL-C were significantly increased in the model group (P < 0.01). Compared with the model group, both the GLPs-M group and the GLPs-H group showed significant decreases in TC, TG and LDL-C (P < 0.05 or P < 0.01), while the GLPs-H group showed a notable increase in HDL-C (P < 0.05). Compared with the model group, both the GLPs-M group and the GLPs-H group showed significant decreases in MDA (P < 0.05 or P < 0.01) and notable increases in SOD, GSH-Px, T-AOC (P < 0.05 or P < 0.01). The GLPs-M group and the GLPs-H group proved a remarkable alleviation in fatty degeneration of hepatic cells.</p><p><b>CONCLUSION</b>G. lucidum polysaccharides can significantly reduce the blood fat level of hyperlipidemic fatty liver in rats and effectively inhibit oxidant stress, showing the effect on preventing and treating hyperlipidemic fatty liver in rats to some extent.</p>
