Fig. 2From: An evaluation of the protective role of vitamin C in reactive oxygen species-induced hepatotoxicity due to hexavalent chromium in vitro and in vivoCr (VI) induced ROS accumulation in the hepatocytes. The cells were treated as described in Fig. 1. a The DCF fluorescence intensity, corresponding to the level of ROS production, was detected. b Intracellular superoxide anion. The data shows the percentage and the fluorescence intensity of positive DHE staining cells from each group. Data represent mean ± SD. *p < 0.05, compared with the control groupBack to article page
