Abstract: We made a study of the lungs of pulmonary edema of 34 bodies died of brain injury, drowning, strangulation, sudden death and intoxication. The lungs of each type of death had distinguishing feature. In brain injury cases, the fact that the congestion,hemorrhage, alveolar and interstitial edema existed simultaneously was the marked feature, and the edema fluid appeared to be homogeneus pink staining coagulum. It has been termed as"neurogenic pulmonary edema" (NPE).IN drowning cases, alveolar edema was very outstanding, but the edema fluid appeared mostly stringy. It has been described as"emphyseme hydroaerique".IN strangulation cases, perivascular edema was prominent.the fragments of fatty and bonemarrow tissues were found in pulmonary arterioles. The pulmonary vascular system thus was proved itself to be a "target organ of strangulation agony" .IN cardiac failure cases, the edema fluid showed granular appearance. In intoxication cases, alveolar edema and Congestion were obvious, but some inflamatory cells were found in pulmonary vascular system and alveoli.
