To determine if alterations of electrolyte balance or sympathetic nervous system activity are present in Dahl salt-sensitive rats (DS) before the onset of hypertension, we compared electrolyte balances, extracellular fluid volume (inulin space), plasma volume (radiolabeled albumin), and norepinephrine turnover in peripheral tissues (heart and interscapular brown fat) in prehypertensive DS and D...

ABSTRACT: This study was done to determine the best value of total electrolyte balance (BET) concerning variables performance and egg quality laying hens. We investigated 240 Hy-Line Brown hens, 30 46 weeks age, adopting completely randomized experimental design, which included five treatments (1000, 1250, 1500, 1750 2000 μeq / kg), 8 repetitions 6 birds per unit. The birds’ eggs were evaluated...

Osmoregulation in marine mammals has been investigated for over a century; however, a review of recent advances in our understanding of water and electrolyte balance and of renal function in marine mammals is warranted. The following topics are discussed: (i) kidney structure and urine concentrating ability, (ii) sources of water, (iii) the effects of feeding, fasting and diving, (iv) the renal...

Fluid and electrolyte disorders are very common in critically ill patients. There are some circumstances in which a patient is placed in intensive care for the management of a specific electrolyte disturbance such as hyponatremia or hyperkalemia. The development of electrolyte disturbances among critically ill patients is also common due to breakdown of homeostatic mechanisms that prevent the d...

Water-Electrolyte Balance in Blood Pressure Homeostasis Much of what human life is about is water (60% of body mass) and a handful of solutes. Of the latter, main cations include sodium, potassium, calcium, and magnesium, and the anions include chloride, bicarbonate, phosphate and organic anions, and proteins. The concentrations of sodium (135–145 mmol/L) and chloride (95–106 mmol/L) predominat...
