The effects of lentinan on enzyme induced lipid peroxidation, xanthine-xanthine oxidase-induced cytochrome c reduction, and on the superoxide-dismutase (SOD) enzyme activity and expression of human lymphocytes and erythrtocytes were studied. Lentinan in low concentration decreased SOD activity of lymphocytes and erythrocytes from healthy subjects. In higher concentration (10 micrograms/ml) lentinan increased the pathologically low SOD activity of erythrocytes and lymphocytes of patients with cirrhosis of the liver. No significant antioxidant (free radical scavenger) effect has been observed in NADPH-induced and Fe3+-stimulated lipid peroxidation and in xanthine-xanthine oxidase system.

D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
