Results： There were diagnostic standard accordance in all. There were mild type carboxyhemoglobin in 7 cases; There were headache, vomiturition, emesis, chest distress; CT were displaied normally in nerve - basal nuclei, but were becomed narrow in gyri, sulci and 3th ventricles of brain. There were severe in 18; They had vague mind, coma, CT were displaied symmetrical low density and in the paUidum of nerve - basal nuclei, and limbic inapparent, there were 3mm ～ 17mm, average 8mm.
