Abstract:
An animal model of acute lung injury was reproduced by intravenous injection of E. coli endotoxin to burned rats. The histological changes of lung were studied using transmission electron microscope. It was found that leukocytes accumulated in the pulmonary capillaries and adhered to endothelia. The WBC count decreased gradually. The level of MDA, lung coefficient and lung water content were increased. The SOD activity was decreased. Pretreatment with SOD could improve the changes mentioned above. This study suggests that oxygen radicals play an important role in acute lung injury induced by burns complicated by endotoxemia.
