Oncotic pressure in solid tumors is elevated.
Oncotic and hydrostatic pressure differences control the movement of fluid and large molecules across the microvascular wall of normal and tumor tissues. Recent studies have shown that the interstitial fluid pressure in tumors is elevated and is approximately equal to the microvascular pressure. Whereas oncotic pressure in blood plasma of various species is known, no data are available on the o...
متن کاملThe effective oncotic pressure of dextran.
Measurement of plasma volume before and after the acute infusion of commercial dextran revealed that all brands tested were hyperoncotic by a factor of approximately 2. By mixing 6% dextran with 0.9% saline in 1:1 proportion a 3% dextran solution was obtained which was nearly isoncotic in our dogs. The most likely explanation for the discrepancy is that the 6% solution contains a high proportio...
متن کاملEffect of plasma osmolality and intraocular pressure on fluid movement across the blood-retinal barrier.
The inward permeability of the blood-retinal barrier to carboxyfluorescein was determined in monkey eyes with and without rhegmatogenous retinal detachment (RD). In the absence of changes in the diffusional permeability of the retinal pigment epithelium (RPE), inward permeability changes reflect changes in fluid flow across the RPE. Intravenous injection of mannitol resulted in a 15 mosmol/kg i...
متن کاملEffect of peritubular oncotic pressure changes on proximal tubular fluid reabsorption.
SPITZER, ADRIAN, AND ERICH E. WINDHAGER. Efect of peritubular oncotic pressure changes on proximal tubular @id reabsorption. Am. J. Physiol. 218(4): 1188-l 193. 1970.-To evaluate directly the effect of changes in postglomerular capillary blood oncotic pressure on fluid reabsorption by proximal tubules of rat kidneys, an in vivo method of microperfusion of peritubular capillaries was devised. Ne...
متن کاملIncreases in plasma oncotic pressure during acute cardiogenic pulmonary edema.
Colloid osmotic pressure (COP) was measured in 95 patients with clinical and radiological evidence of acute cardiogenic pulmonary edema. Fifty patients who were admitted for coronary observation but in whom acute myocardial infarctin was excluded, and 21 patients who had sustained acute myocardial infarction without evidence of left ventricular failure served as controls. Significantly higher ...
