Fig. 4From: Proanthocyanidin and sodium butyrate synergistically modulate rat colon carcinogenesis by scavenging free radicals and regulating the COX-2 and APC pathwaysAntioxidant enzyme activities in the sera of normal and treated rats. A lipid peroxidation activity (MDA); B SOD activity; C GSH activity; D TAC levels. *Significance versus G1 at P < 0.05; **significance versus G2 and G3 at P < 0.05; ***significance versus G1, G2, G3, and G4 at P < 0.05 (ANOVA). Samples from 5 rats/group were subjected to the antioxidant enzyme activity assay. MDA, malondialdehyde; SOD, superoxide dismutase; GSH, reduced glutathione; TAC, total antioxidant capacityBack to article page
