Cation Movements in the High Sodium Erythrocyte of the Cat
نویسندگان
چکیده
The uptake of (42)K and (24)Na by cat erythrocytes was investigated. Under steady-state conditions, the nontransient component of (42)K influx was found to be 0.18 +/- 0.01 meq/liter RBC/hr and insensitive to ouabain (100 microM); the corresponding value for (24)Na was 17 +/- meq/liter RBC/hr. A study was made of the effects of anions upon cation movements in these and other mammalian red cells. Iodide was found to inhibit markedly (>50%) Na inward movements in cat and dog but not in the other erythrocytes. An increase (15-30%) in K uptake in the presence of iodide was noted in all the mammalian cells studied.

Effect of cetiedil on cation and water movements in erythrocytes.
Cetiedil is a potential antisickling agent whose major effect appears to be at the erythrocyte membrane. To test the hypothesis that cetiedil alters cation transport, we studied the effect of the drug in promoting changes in cell water (Wc), cell sodium (Nac), and cell potassium (Kc). Results are quite different depending on the presence or near absence of intracellular ATP. With fresh cells, 1...
متن کاملEffect of cetiedil, an in vitro antisickling agent, on erythrocyte membrane cation permeability.
Cetiedil has been reported to relieve painful crises in sickle cell anemia and to have antisickling properties in vitro. The drug alters neither oxygen affinity nor the solubility of deoxyhemoglobin S. Because the viscosity of the erythrocyte interior and the kinetics of gelation are dependent on the concentration of hemoglobin, we postulated that cetiedil might inhibit sickling by modifying er...

The reported work is on the preparation and characterization of polyvinyl alcohol -g- Polyacrylic acid (PVA-g-PAA)/ Polybenzimidazole sulfone (PBIs) cation exchange membrane used for the electro dialysis of sodium chloride solution. The polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. The polymer ...
متن کاملEffects of Fluoride on Potassium and Sodium Permeability of the Erythrocyte Membrane
One of the most important features of cell membranes is their capacity to discriminate between ions of different sign or different chemical nature. In the erythrocyte membrane, coulombic forces seem to govern the discrimination between anions and cations. There is reason to believe that, without impeding the movements of anions, positive fixed charges impose a severe restriction on the movement...
