ResumoGlycyrrhizae radix water extract (GRWE) and its two major constituents glycyrrhizin and 3-glycyrrhetinic monodesmoside, significantly suppressed LDH leakage and MDA release, whereas glycyrrhetinic acid had no effect. On the other hand, in rats subjected to ischemia-reperfusion, the activities of endogenous antioxidant enzymes including catalase and glutathione peroxidase showed recovery, whereas the levels of urea nitrogen and creatinine in serum were reduced by administration of glycyrrhizin orally for 30 days prior to ischemia-reperfusion. These results indicate that GRWE and its two constituents may be promising for amelioration of hypoxia (ischemia)-reoxygenation (reperfusion) injury and improvement of renal function by acting directly or indirectly as antioxidant and oxygen radical-scavenging agents.
