Distribution and transcapillary exchange of albumin in congestive heart failure.
1N T GENERAL, previous investigators have concluded that the capillary permeability to proteins is either normal or increased in patients with congestive failure." I t is difficult to reconcile such results with the consistent finding of increased plasma volume in congestive heart failure. In a previous study of normal individuals, iodinated serum albumin was used to measure the transcapillary ...

متن کاملNMR studies of 5-hydroxytryptamine transport through large unilamellar vesicle membranes.
Nuclear magnetic resonance techniques developed to study membrane permeability in closed membrane systems have been used to investigate transport of 5-hydroxytryptamine across the phospholipid membranes of large unilamellar vesicles. The vesicles, modeling the 5-hydroxytryptamine storage organelles of blood platelets, contained a high internal level of ATP buffered at a pH low relative to the e...
متن کاملResponse of cerebral circulation to topical histamine.
To study the effect of histamine (HA) on brain blood flow and capillary permeability, bilateral parietal craniectomies were made in cats anesthetized with nitrous oxide and ketamine. The dura was removed and solutions of HA in mock cerebrospinal fluid (CSF) in varying concentrations ranging from 10(-5) M to 10(-1) M were irrigated continuously onto the exposed brain while local cerebral blood f...
متن کاملDistribution and metabolism of I131 labeled human serum albumin in congestive heart failure with and without proteinuria.
The role of serum albumin in the causation of cardiac edema has been disputed. Starling (1) postulated that circulatory stasis resulting from cardiac insufficiency is responsible for anoxia and increased permeability of the capillary membrane, the consequence of which is the passage of albumin and water into the extravascular spaces. Although Smirk (2) observed evidence of increased capillary p...
