Alteration of oxidant stress related factors. (A) The level of MDA was determined in serum collected from mice using a lipid peroxidation assay kit that could detect MDA at 0.1 nmole/mg to 20 nmole/mg; (B) The expression level of SOD was measured in the homogenate of liver tissue collected from subset groups. The intensity of each band was determined using an imaging densitometer and the relative level of each protein was calculated based on the intensity of actin protein as an endogenous control. Data represent the means ± SD of three replicates. a, p < 0.05 compared to the no treatment group; b, p < 0.05 compared to the vehicle/CCl4 treated group.
