Effect of PSPs on neutrophil ratio and inflammatory factor content in BALF of the ALI rats. (A) Proportion of neutrophils in BALF of the different groups of rats. (B) TNF-α, (C) IL-1β, (D) IL-6 and (E) IL-8 levels in BALF of the different groups of rats. (F) mRNA expression of TNF-α, IL-1β, IL-6 and IL-8 in lung tissues of the different groups of rats. A total of 10 rats in each group, each indicator for each rat was tested at least 3 times independently; ***P<0.001 vs. the control group; ##P<0.01 and ###P<0.001 vs. the LPS group. PSPs, Polygonatum sibiricum polysaccharides; LPS, lipopolysaccharide; BALF, bronchoalveolar lavage fluid; ALI, acute lung injury; TNF-α, tumor necrosis factor-α; IL, interleukin. Groups: L-PSP, 20 mg/kg; M-PSP, 40 mg/kg; H-PSP, 80 mg/kg PSPs.
