It could suppress the expression of IL-1 and NF-B, limiting septic injury (Fujioka et al., 2 administration increased the HO-1 expression and the number of anti-inflammatory cytokines, IL-10, in human umbilical vein endothelial cells stimulated by LPS and lung tissue of lung-injured mice (Chen et al., 2 could prevent acute pancreatitis in mice effectively by enhancing the expression of Hsp60 protein, a heat stress protein, that stimulated synthesis by high temperature to protect itself, in the early stage (Yin et al., 2021)
