Net sodium influx under K-free conditions was independent of the intracellular sodium ion concentration, [Na](i), and was increased by ouabain. Unidirectional sodium influx was the sum of a component independent of [Na](i) and a component that increased linearly with increasing [Na](i). Net influx of sodium ions in K-free solutions varied with the external sodium ion concentration, [Na](o), and...
Hemoglobin-based oxygen carriers (HBOC) have been primarily studied for blood loss treatment. More recently infusions of HBOC in euvolemic subjects have been proposed for a wide variety of potential therapies in which increased tissue oxygenation would be beneficial. However, compared with the exchange transfusion models to study blood loss, less is known about HBOC oxygen delivery and vasoacit...
Single muscle fibers were exposed to solutions made hypertonic (approximately 460 milliosmols/kg water) by addition of either NaCl, glycerol, urea, acetamide, ethylene glycol, or propylene glycol. The changes in either the fiber twitch tension or the volume were measured. In the case of NaCl both fiber volume and twitch tension fall rapidly to 64 and 27% of the respective initial value. These t...
Atrial natriuretic peptide (ANP) controls lipolysis in human adipocytes. Lipid mobilization is increased during repeated bouts of exercise, but the underlying mechanisms involved in this process have not yet been delineated. The relative involvement of catecholamine- and ANP-dependent pathways in the control of lipid mobilization during repeated bouts of exercise was thus investigated in subcut...
Background: Patients with chronic renal disease, if not treated appropriately, will be usually terminated into an irreversible stage known as End Stage Renal Disease (ESRD), the final stage of kidney disease. End stage renal disease patients cannot excrete the appropriately potassium ion through the kidney. Among the crystalloid solutions, normal saline is devoid of potassium so it is ...
Background: This study compared the effect of Voluven and Ringer solution in cardiopulmonary bypass on the bleeding after the surgery and renal function in coronary artery bypass graft surgeries. Methods: Two types of prime solution including ringer - as Crystalloid- and Voluven were used in two groups and compared in terms of bleeding and renal function during the first 24 hours after the surg...
This study examined the role of Ca(2+) in regulatory volume decrease by Necturus erythrocytes. Hypotonic shock (50% tonicity) stimulated an increase in cytosolic free Ca(2+), detected using epi-fluorescence microscopy and the fluorescent Ca(2+) indicator fluo-4-AM (10 microM). A similar increase in fluorescence did not occur under isosmotic conditions, unless cells were exposed to the Ca(2+) io...
