【Abstract】 Objective:To study the pathological changes of lung injury induced-burn and the protective effects of Rhadiola Astragalus Codonopsis Compound (RACC) on lung in rats with severe burn at high altitude.Methods:A total of 180 rats, exposed in altitude of 3 480m for 1 week, were randomly divided into test group (84 animals), in which the rats were burnt up to Ⅲ°and the RACC was taken by gastric canal before burn, test control group (84 animals), in which the burnt rats were taken normal saline before burn and normal group (12 animals),in which the healthy rats were taken normal saline only. The pathological observation of lung was performed by microscopy among three groups after 3h, 6h, 12h; 1 day, 2 days, 3 days and one week burn.Results:There were obviously differences of pathological changes in three groups after 3hrs burn. Pulmonary changes of morphology in the test control group were the most severe, the test group mild and no changes in the normal group.Conclusion:The injury of lung was severe on pathology in the rats burnt at high altitude, but the RACC could protect the rats from the severe lung injury.更多还原
