Early morphological alterations of the rat lung with increased intracranial pressure. II. A scanning electron microscopic study using different fixation procedures.
Pulmonary edema following intracranial pressure elevation was studied by means of scanning electron microscopy. Using three different fixation procedures-immersion, vascular perfusion, and tracheal instillation-the various features of intraalveolar edema formation could be demonstrated: capillary congestion, intraalveolar proteinious exudate, and capillary hemorrhage.
