Permeability of rabbit heart capillaries to nonelectrolytes.
VARGAS, FERNANDO, AND JOHN A. JOHNSON, Permeability of rabbit heart capillaries to nonelectrolytes. Am. J. Physiol. 2 r 3(1> : 87-93. 1967. -Isolated perfused rabbit hearts were used to study the permeability characteristics of their capillaries with respect to inulin, raffinose, sucrose, and urea, The method used involved a continuous weighing of the isolated perfused heart. Each heart was iso...
متن کاملPermeability of the corneal endothelium to nonelectrolytes.
The endothelial surface of the isolated rabbit cornea was perfused with modified KEI medium, according to the method reported previously. This in vitro cornea maintained its thickness within the normal range even after the epithelium ivas removed. The endothelial permeability of these in vitro corneas to tritiated water, >C-labeled urea, sucrose, and inulin teas determined. The reflection coeff...

OF SPECIAL INTEREST XANTHINURIA AND HEMOCHROMATOSIS. J. H. Ayvazian. From Veterans Administration Hospital, N. Y. New England J. Med. 270: 18-22, 1964. A 47-year-old white male with hemochromatosis manifested by hepatomegaly, diabetes, greatly elevated serum iron, completely saturated iron binding capacity and hemosiderinuria, but only a trace of marrow hemosiderin, had a serum uric acid of les...
متن کاملPermeability of Erythrocytes to Radioactive Potassium
The diffusion coefficients for the exchange of potassium across the membrane of erythrocytes of humans, rats, and rabbits have been determined by the use of artificially radioactive potassium, both into and out of the erythrocytes both in vitro and in vivo. The diffusion coefficients found in minutes(-1) were 0.2 to 0.25 x 10(-3) for human, 0.32 to 0.665 x 10(-3) for rabbits, and 1.0 x 10(-3) f...
متن کاملTracer Determinations of Human Red Cell Membrane Permeability to Small Nonelectrolytes
A flow system has been used to determine the permeability of human red cell membranes to four small nonelectrolytes labeled with (14)C. The permeability coefficients, omega, in units of mol dyne(-1) sec(-1) x 10(15), are: ethylene glycol, 6; urea, 13; formamide, 22; and methanol, 131. The values for urea and formamide are in good agreement with values obtained by Sha'afi, Gary-Bobo, and Solomon...
