Ultrastructural alterations of the rat lung following marked increase in intracranial pressure involve interstitial and intraalveolar hemorrhagic and proteinous edema accumulation developing within a few minutes. Capillary endothelium reveals intracellular bleb formations, scallops, and increased pinocytic activity. There is no separation of intercellular junctions both in endothelium and epithelium of the alveolar wall. The common basement membrane of the air-blood-barrier seems to be intact, whereas type I pneumonocyte of the alveolar epithelium shows similar bleb formations as the endothelium. Type II pneumonocyte elicits imposing cytoplasmic protrusions. Edema fluid contains electron dense components and washes out surface active lining layer of lung alveoli. [ABSTRACT FROM AUTHOR] |
