Melatonin reduces bacterial translocation and apoptosis in trinitrobenzene sulphonic acid-induced colitis of rats

Figure 1 Serum TNF-α and endotoxin concentrations in rats. Vertical columns and error bars represent mean ± SD respectively. ^bP < 0.01 vs colitis and colitis + melatonin groups, ^aP < 0.05 vs colitis group.

Figure 2 Colon MPO concentrations in rats. Vertical columns and error bars represent mean ± SD respectively. ^bP < 0.001 vs control and colitis + melatonin groups, ^dP < 0.001 vs colitis group.
