Antioxidant effect of Lycium barbarum (GOJI), Vaccinium macrocarpon (CRAN) and Vaccinium myrtillus (BLUE). Mice were treated during 10 days, twice a day (50 and 200 mg/kg, p.o.). Control animals received only vehicle and positive control indomethacin (10 mg/kg, i.p., INDO). After treatment, antioxidant activity was determined in liver. (a) Represents effect on thiobarbituric acid reactive substances, in (b), reduced glutathione concentration and in (c), catalase activity. Bars represent mean ± standard error of mean of 5–6 animals for group. ANOVA followed by Dunnett's post hoc test, *P < 0.05
