changes in dietary electrolyte balance influence the metabolic fate of protein and many amino acids. furthermore, acid-base condition is achieved in part by the alteration of dietary amino acids pattern and quantity. therefore, a trial was conducted in a completely randomized design to evaluate performance, carcass characteristics, plasma electrolyte and uric acid concentrations of 19 and 28-da...

Carp (Cyprinus carpio) were exposed to environmental water pH (pHw) step changes from 7.4 to 5.1, 5.1 to 4.0 and 4.0 to 3.5 pH, PCO2, PO2 and lactate in dorsal aortic blood, [Na+], [K+] and [Cl-] in dorsal aortic plasma, base loss, and ammonia excretion were determined as a function of time after each pHw step change. At pHw 5.1 the measured blood acid-base and electrolyte parameters remained e...

The purpose of this study was determine effects of ingestion carbohydrate-electrolyte beverage drink to improve exercise performance in the heat. Ten male subjects (age 1830 years) were subjected to cycle ergometer at 63.5 ± 3.3% of maximal O2 consumption (VO2max) with a pedal speed of 60 rpm until they became fatigued. They were given a drink of carbohydrate-electrolyte at a concentration of 6...

In 48 cases the left middle cerebral artery was occluded under light barbiturate anaesthesia using a transorbital approach. The animals were kept alive for 1, 2, and 4 hours after vascular occlusion. Regional cerebral blood flow was measured by the intracardiac microsphere injection technique before ischemia, 15 min after the onset of ischemia, and at the end of experiments. The density of regi...

background nowadays percutaneous nephrolithotomy (pcnl) is performed in prone and supine positions. physiologic solutions should be used to irrigate during pcnl. irrigation can cause hemodynamic, electrolyte and acid-base changes during pcnl. objectives the current study aimed to compare the electrolyte, hemodynamic and metabolic changes of prone and complete supine pcnl. patients and methods i...

Pregnancy affects the physiology of the pregnant woman particularly the endocrine, cardiovascular and the renal systems. This work was therefore set to ascertain the state of electrolytes in pregnancy and how it affects blood pressure using multiparity as a factor. One hundred and twenty (120) women were used in this study. The non-pregnant groups were the nulliparous (control) and grand multip...

1. Analyses have been made of the electrolytes and proteins of serum and transudates from human subjects. 2. The distribution ratios of HCO(3), Cl, Na, and H(+) deviated from unity as predicted by the Gibbs-Donnan law for similar heterogeneous systems. 3. Analyses of serum, and of artificial salt solutions approximating edema fluid in composition, after equilibration across collodion membranes ...

We evaluated a new analyzer designed for point-of-care testing of blood gases, sodium, potassium, ionized calcium, and hematocrit. The Gem Premier (Mallinckrodt) system has two components: the analyzer and a disposable cartridge. Analysis takes place in the cartridge, which contains the electrochemical sensors, the calibrants, the reagents, the sampling stylus, and the waste container. The syst...
