Efflux and Influx of Erythrocyte Water

Efflux and Influx of Erythrocyte Water

Rabbit erythrocytes were washed in buffered NaCl solutions isotonic with rabbit serum (Delta(t) -0.558 degrees C.) and suspended in buffered NaCl solutions of tonicity equidistant from intracellular tonicity (Delta(t) = -0.558 degrees C. +/- 0.112 degrees C.) of varying pH and incubated at varying temperatures. After incubation, the freezing point depression (Delta(t)) was measured on the super...

Extracellular and Metabolic Factors Affecting the Efflux and Influx of Erythrocyte Water

Water exchanges between rabbit erythrocytes and extracellular solutions equidistant from intracellular osmolarity were studied by freezing point depression techniques. Water efflux was always less than water influx and both were hypotonic to the intracellular and extracellular fluids. The magnitudes of these water exchanges were not dependent on the presence of extracellular cation. Stimulation...

Erythrocyte magnesium influx and efflux in solid tumor bearing mice.

Mg metabolism is modified in tumors and tumor-bearing organisms. In particular cancer patients often display elevated erythrocyte Mg levels. For a better understanding of the increased erythrocyte Mg content, we attempted to determine Mg fluxes in erythrocytes from tumor-bearing mice by Mg stable isotopes, using a method developed in our laboratory. To characterize the animal Mg status, blood a...

adrenal cortex and brown adipose tissue: Crompton et al., 1978; Nicholls, 1978; Al-Shaikhaly et al., 1979), the fluxes of Ca2+, Na+ and H+ may be integrated into a cycle (Fig. l), for which evidence has been published (Crompton el al., 1976; Crompton & Heid, 1978; Nicholls & Scott, 1980). In cardiac muscle the cycle would never reach steady state, as it does in vitro, since the [Caz+] in the cy...
