Indoxyl sulfate decreased antioxidant enzyme activities. Unilateral nephrectomized mice were intraperitoneally injected with indoxyl sulfate (IS, 0 and 100 mg/kg) and the indoxyl sulfate-injected mice were orally given with AST-120 (0 and 400 mg/kg) for 7 weeks. The prefrontal cortical tissues were collected and subjected to the measurement of Mn-SOD activity, Cu/Zn-SOD activity, Catalase activity, and GPx activity. *p < 0.05 vs. control group, and #p < 0.05 vs. indoxyl sulfate alone (IS) group, n = 8.
