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

Figure 4 The effect of melatonin on total protein levels and interleukin IL-1β levels in the liver of animals that underwent bile duct ligation surgery. The data are expressed as the mean ± standard error of the mean. Significant decrease/increase in the bile duct ligation (BDL) group in relation to the control (CO) and the CO + melatonin (MLT) groups (^aP < 0.001). Significant increase in the BDL + MLT group in relation to the BDL group (^bP < 0.001). A: Total protein; B: IL-1β.
