[Effect of lugu Ganoderma lucidum on low-density lipoprotein oxidation and monocyte adhesion to endothelium]

To study the effect of Lugu Ganoderma Lucidum (LGL) on low-density lipoprotein (LDL) oxidation and monocyte adhesion to endothelium (AdM-E) induced by oxydative LDL and advanced glycosylation endproducts (AGE) by using serum pharmacological technique.LDL oxidation was determined by measuring the thiobarbituric acid reactive substances in the supernatants, and AdM-E was determined by measuring myeloperoxidase activity of adherent monocyte.Serum derived from rats 0.5 hrs, 1 hr, 2 hrs, 3 hrs after LGL administering 0.12 g/kg once and 0.5 hrs, 1 hr after LGL administering twice showed no significant effect on LDL oxidation, but the serum from rats 2 hrs, 3 hrs after LGL 0.12 g/kg administering twice or from rats after 10 successive days LGL administering in dose of 0.12 g/kg, 0.24 g/kg and 0.72 g/kg, all could lower the LDL oxidation (P0.05). Besides, the serum from rats with 10 days LGL administering of all dosages also could inhibit AdM-E induced by AGE (P0.05), and those of 0.24 g/kg and 0.72 g/kg could inhibit AdM-E induced by oxydative LDL (P0.05).LGL could decrease LDL oxidation and AdM-E induced by AGE or oxydative LDL.
