The changes of redox status in hypoxic cells by different pretreatment. (A) showed the alteration of intracellular GSH and GSSG contents in HepG2 cells under hypoxic condition; (B) showed the ratios of GSH and GSSG in HepG2 cells under hypoxic condition. (^◆p < 0.05, ^#p < 0.01, as compared with hypoxia control; ^▲p < 0.05, *p < 0.01, as compared with the cells by NAC treatment).
