Abstract

We studied the effects of epifamin and melaxen on serum content of reduced glutathione and activities of glutathione peroxidase, glutathione reductase, and NADPH-generating enzymes (glucose-6-phosphate dehydrogenase and NADP-isocitrate dehydrogenase) in rats with type 2 diabetes mellitus. The concentration of reduced glutathione was decreased in rats with this disease (by 1.8 times), but increased after treatment with epifamin and melaxen (by 1.6 and 1.7 times, respectively). Activities of glutathione peroxidase, glutathione reductase, and NADPH-generating enzymes returned to the control level. Correction of melatonin concentration after treatment with the test drugs was probably followed by inhibition of free radical processes. The observed changes were accompanied by normalization of activity of the glutathione antioxidant system and NADPH-generating enzymes required for normal function of this system.
