ЕКСТРАКТ МОМОРДІКИ ПРИГНІЧУЄ ОКИСНИЙ СТРЕС ТА ЗБІЛЬШУЄ ГЕМОЛІТИЧНУ СТІЙКІСТЬ ЕРИТРОЦИТІВ КОРОПА ЗА ВПЛИВУ ГЛЮКОЗИ

Abstract

Phytoextracts and natural antioxidants should provide promising results in therapeutic intervention for diabetes mellitus when they include into medical treatment scheme. The present study aimed to investigate the effect of Momordica charantia phytoextract alone and in complex-form with nano zinc oxide as well as zinc compounds on rate of hemolysis and oxidative stress parameters in Cyprinus carpio red blood cells (RBC) after their exposure to high glucose in vitro. The results have shown that the glucose treatment was capable to promote an increase in oxidative damage of lipids and proteins, the break of balance in antioxidant defence and enhance the rate of hemolysis and methylglyoxal concentration. When glucose-treated RBC were probed with M. charantia extract, nZnO- Momordica, nZnO and zinc picolinate specific response to different co-exposures was disclosed. Zinc picolinate in general had no significant effect on the studied parameters with few exceptions, then ZnO nanoparticles made glucose effects more profound. Momordica in herbal extract form and, particularly, in green synthetized ZnO nanoparticle have caused the decrease in lipid and protein peroxidation, glutathione trasferase activity, rate of hemolysis and methylglyoxal, and the increase in catalase and glutathione up to control baseline. These results have pointed to the necessity of further investigations of antihyperglycemic activity of Momordica and mechanistic explanation of its potentials.
