Thyrocalcitonin, EGTA, and urinary electrolyte excretion.
The infusion of thyrocalcitonin (TCT) into thyroparathyroidectomized rats, given either no exogenous parathyroid hormone or a constant infusion of this hormone, leads to a transient phosphaturia and a decreased excretion of urinary magnesium, calcium, and hydroxyproline without a change in glomerular filtration rate. The changes in phosphate excretion may be due to a direct effect of the hormon...
متن کاملElectrolyte and Water Excretion
The increased capacity of hypertensive subjects to excrete sodium is frequently reduced by effective antihypertensive drug treatment. This reduction in sodium excretion is not necessarily associated with changes in renal hemodynamic function or resting sodium excretion. It appears to result from an alteration in renal tubular activity. The findings suggest that the arterial pressure per se may ...
متن کاملEffects of tap water, electrolyte solution, and spontaneous and furosemide-stimulated urinary excretion on thirst.
AIM To contrast the effects of various modifications of body fluid volumes on thirst as reported by healthy volunteers. METHODS Ten male volunteers aged between 19 and 37 years (mean 22 years) underwent four experiments each, which comprised infusion of 400-800 mL of acetated Ringer's solution and intake of 600 mL of tap water. Half of the experiments were preceded by volume depletion (median...
متن کاملElectrolyte excretion in respiratory failure.
Patients with chronic emphysema and pulmonary insufficiency commonly arrive at a new steady state in which the carbon dioxide pressure in the blood is increased and the pH lowered; this situation can be prolonged for months during which these patients must be in acid-base balance. This equilibrated state of mild respiratory acidosis is, at times, upset by complicating pneumonitis which aggravat...
متن کاملEffect of acute environmental heat stress on urinary water and electrolyte excretion in the rat.
Plasma cortisol and urinary excretion of water, sodium, potassium, calcium and magnesium have been studied in the rat after application of heat stress. There was a significant increase in plasma cortisol level after exposure to heat. During heat stress complete cessation of urine formation was observed. In the next 30 min there was statistically significant increase in the urinary excretion of ...
