Ultrastructural abnormalities in increased-permeability pulmonary edema. 1985

K H Albertine

A general clinical impression is that increased microvascular permeability following acute lung injury always leads to pulmonary edema. The ARDS is a final pathway of acute lung injury. A number of agents may initiate acute lung injury, either directly or indirectly, via cellular and humoral mediators. Clinical and experimental animal studies indicate that both the microvascular and alveolar-airway barriers are susceptible to injury. Unfortunately, the spectrum of cellular damage is nonspecific and quite uniform, regardless of the injurious agent. Thus pathologic examination often reveals little about the exact underlying etiology of the lung injury. This situation has minimized the diagnostic value of lung biopsies in clinical cases of increased-permeability pulmonary edema. Nonetheless, the pathologic information has been, and will continue to be, invaluable to understanding the structural and functional relationships present in experimental models of increased-permeability pulmonary edema.

Pulmonary edema prevents efficient PULMONARY GAS EXCHANGE in the PULMONARY ALVEOLI, and can be life-threatening. Wet Lung,Edema, Pulmonary,Edemas, Pulmonary,Pulmonary Edemas,Lung, Wet,Lungs, Wet,Wet Lungs
D001798 Blood Proteins Proteins that are present in blood serum, including SERUM ALBUMIN; BLOOD COAGULATION FACTORS; and many other types of proteins. Blood Protein,Plasma Protein,Plasma Proteins,Serum Protein,Serum Proteins,Protein, Blood,Protein, Plasma,Protein, Serum,Proteins, Blood,Proteins, Plasma,Proteins, Serum
D002199 Capillary Permeability The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.
