Methods: Forty mice were divided into four groups randomly:normal group,model group,ligation group and treatment group.The model was made by the method of partly ligating the recta outside the body.The level of endotoxin in blood plasma was measured by dynamic nephelometric method and the content of TNF-a in blood serum was detected by the method of radioimmunity.(2)After the mice were killed,their left lungs were taken out for bronchi-alveoli fluid, then the content of MDA in BALF was tested by TBA method.(3)The vitality of PAM in BALF was countied on the counting set of erythrocyte,and the blue-dyed cellswere counted, then the percentage of PMN was worked out.(4)The pathological features of the mice\'s lung tissue were observed with routine and ultramicro pathological mechanism.
