Melatonin prevents oxidative stress, inflammatory activity, and DNA damage in cirrhotic rats

Figure 5 The effect of melatonin on the quantification of immunohistochemistry analysis and the expression of NF-kB with the Western blot technique in the livers of animals that underwent bile duct ligation surgery. The data are expressed as mean ± standard error of the mean. Significant increase in the bile duct ligation (BDL) group in relation to the control (CO) and CO + melatonin (MLT) groups (^aP < 0.001). Significant decrease in the BDL + MLT group in relation to the BDL group (^bP < 0.001); A: Expression of positive pixels; B: Relative ratio (NF-kB/β-actin).
