[Pulmonary ultrastructural changes in dogs following experimental hemorrhagic shock (author's transl)].

The authors have studied the ultrastructure of the lung in dogs following experimental hemorrhagic shock. They found intra-alveolar edema, red cells in the alveolar sac, disappearance of the substance of the lamellated osmiophilic bodies and cellular degeneration. Correlation among these alterations and increase of capillary permeability as well as consumption of surfactant secretion were established.
