CAT and Nephropathy: The current data showed that TG positively correlated significantly with renal MDA (P = 0.01 and r = 0.96) and catalase (P = 0.003 and r = 0.98) as indicators of oxidative stress, while negatively correlated with renal NO, (P = 0.04 and r = -0.90) (Table 4) suggesting an association between renal lipid peroxidation and obesity associated nephropathy.
