Results are expressed as mean ± standard error of mean. *p<0.05 is significant when compared with control using Student’s t test. ≠p<0.05 is significant using ANOVA. Abbreviations: GSH-reduced glutathione; GSSG-oxidized glutathione; GSH/GSSG- reduced/oxidized glutathione ratio; MDA- malondialdehyde.
