Fig. 2From: The mechanism of nicotinamide on reducing acute lung injury by inhibiting MAPK and NF-κB signal pathwayThe results of H&E staining and tissue score of lung injury. Control means no treatment, NAM means NAM treatment, LPS means LPS treatment, LPS + NAM means NAM + LPS treatment, DEX means NAM + DEX treatment. a–e H&E staining of lung tissue in control, NAM, LPS, LPS + NAM and LPS + DEX groups. f Histological score of lung in each group. The values are presented as the mean ± SD (*p < 0.05, **p < 0.001, ***p < 0.001 and ****p < 0.0001)Back to article page
