AIM: To study the antioxidant effect of Ganoderma polysaccharide peptide (GLPP) and its mechanism.
METHODS: Copper was used as oxidant to induce low lipoprotein (LDL) oxidative modification, and alloxan was given i.v. to induce reactive oxygen species (ROS) injury in mice.
RESULTS: GLPP decreased oxidation of LDL and the relative electrophoretic mobility (REM) of oxidative product of LDL. After GLPP was given i.p. for 20 days, the concentration of malondialdehyde(MDA) in serum and heart of mice was decreased. The GSHpx enzyme activity was increased, while the SOD level was decreased. The catalase(CAT) levels were not significantly changed by GLPP.
CONCLUSION: GLPP showed antioxidant effect by scavenging ROS or enhancing the enzyme activity of GSHpx in vivo and in vitro.
