ABSTRACT
Objective:
To investigate the influence of dehydroepiandrosterone(DHEA) on antioxidant capacity of Raji cell cultured in vitro.Methods:
Raji cell line was cultured in vitro in the presence of DHEA and/or phenazine methosulfate(PMS), some antioxidant enzymes including glucose-6-phosphate dehydrogenase activity(G-6-PD),glutathione peroxidase activity(GPX), glutathione reductase activity(GR) and intracellular glutathione(GSH) concentration of the DHEA pretreatment cells were evaluated. meanwhile, these results were compared with that from the respective control cells.Results:
(G-6-PD) activities were suppressed significantly and no changes in activities of GPX,GR and intracellular GSH concentration were occurred while Raji cells were cultured in the presence of DHEA at concentration more than 5.0?mol/L . On the other hand, the DHEA pretreatment cells show no changes in (G-6-PD,)GPX,GR activities and significantly decreased GSH concentration(P
