Changes in IL-19 and antagonizing effects of meloxicam on endotoxin-induced acute lung injury in rabbits / 解放军医学杂志

ABSTRACT

Objective To investigate the changes in interleukin-19(IL-19)in lungs of rabbits with acute lung injury(ALI)induced by endotoxin(ET),so as to study the mechanism of injury of ET to the lung and the protective mechanism of meloxicam.Methods Twenty four male Japanese flap-eared white rabbit was randomly assigned to three groupscontrol group,ET-treated group and treatment with meloxicam group.Rabbit ALI model was replicated with intravascular ET injection(700?g/kg),and meloxicam was intravenously injected(2.5mg/kg)for treatment group.The content of IL-19 was measured with ELSIA method and the changes in malondialdehyde(MDA)and superoxide dismutase(SOD)were determined in every group.Results IL-19 expression in ET challenged group was significantly higher than that in control group(P
