Abstract:
U1 trastuctrural changes of myocardium and lungs from 6 cases died of cranioce-rebral penerating gunshot wound 2 hours after injury is reportcd.In all cases theelectron microscopy of the myocardial and lung tissue samples showed the similar ultrastructural morphological changes of the cells and interstitial tissues.The mostpr-ominent ultrastructural changes of myocardium were disorderly arrangement of the Zband.focal dissociation of the myofibrills,mitochondrial swelling with decreasing ofmatrix density and disruption of cristae,and interstial edema.The changes of theung tissue were increasing of width of alveolar septa with decreasing of the electron density.Aggregation of neutrophils in the capillaries of alveolar septa and some alveolar space was observed.The significance and the pathogenesis of the mainpathological changes were discussed.It is suggested that the pulmonary interstitialedema was neurogenic.The pulmonary edema may be manifested as interstitial edemaor intra-lveolar edema depending upon the time elapsed after the gunshot injury.
