it was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (ap). it seems that some other types of mechanisms must be involved in ap propagation. in this article, we...

The stationary intracellular potassium concentration in E. coli B 525 has been studied as a function of the extracellular potassium and sodium concentrations. The ratio of extracellular to intracellular potassium concentration is shown to be a linear function of the extracellular potassium concentration if the extracellular sodium concentration is low (20 mmoles/1). In the case of high sodium c...

Abstract Background: Water and electrolyte balance are critical for the maintenance of general health. Exercise creates much variation in renal homodynamic and electrolytes excretion. Sauna is also an extreme hot environment placing an individual in heat stress. The aim of this study was to compare the effects of one session aerobic activity and sauna on serum and urinary sodium and potass...

cant correlation between plasma aldosterone and plasma potassium concentration (r = +0.74, P < 0.001) and between changes in the concentration of plasma aldosterone occurring in individual patients and the corresponding changes in plasma potassium concentration (r = +0.52, P < 0.01). There was no significant change in plasma sodium concentration, and plasma corticoid concentration, which was mo...

BACKGROUND Hypokalemia and paralysis may be due to a short-term shift of potassium into cells in hypokalemic periodic paralysis (HPP) or due to a large deficit of potassium in non-HPP. Failure to make a distinction between HPP and non-HPP may lead to improper management. Therefore, we evaluated the diagnostic value of spot urine tests in patients with hypokalemia and paralysis during 3 years. ...

Extended Abstract Introduction and Objective: Moldavian balm (Dracocephalum moldavica L.) is a medicinal plant belonging to the Lamiaceae family which uses as stomachic, sedative and healing of wound. Non-uniform establishment of medicinal plants in arid zones soil especially under abiotic stresses such as salinity is the most important problems in cropping and developing of these plants. Mat...
