Oliiarnyk OD, Velykyi MM, Makhnevych TR: [Features of the inhibition of catalase activity by 3-amino-1,2,4-triazole in erythrocytes and liver of rats with streptozotocin diabetes]. Ukr Biokhim Zh. 1999 Jan-Feb;71(1):77-82.
Lipid peroxidation was intensified by streptozotocin induced diabetes mellitus in erythrocytes and liver. Activity of antioxidant enzyme superoxide-dismutase was decreased, activity of catalase was increased. Concentration of lipid peroxidation products was decreased after nicotinamide injections. It was investigated liver- and erythrocyte catalase inhibition in the presence of 3-amino-1,2,4-triazole. Effective inhibitor concentration for liver catalase by streptozotocin induced diabetes mellitus was 10 mM, by control-20 mM. Ascorbic acid induced catalase inhibition in the erythrocytes by diabetes mellitus increased by ascorbic acid concentration from 25 to 150 mM. [DHAA]/[AA]-ratio increased from 0.26 by control to 1.6 by diabetes mellitus and decreased to 0.44 after nicotinamide injections. |
