Research Abstract |
Circulating erythrocytes are constantly exposed to oxidative stress as a result of the high cellular concentration of oxygen and hemoglobin, which is a source of the reactive oxygen species. Exposure to oxidative stress dramatically alters the function of the erythrocyte membrane, such as elevation of viscosity, decrease of deformability. Saponins (especially ginsenosides Rg2 & Rh1) from Ginseng Panax protect the rheological functions of erythrocytes against oxidative stress by preventing the oxidation of SH-groups in band 3 protein. The glucose metabolism were suggested to participate in mechanism of protections.
