Measurement of ionized calcium is more important than measurement of total calcium in serum samples. In the present study, equations were derived from complexation and acid dissociation equilibrium equations, and were used to determine the concentration of ionized calcium from the observed serum concentrations of total calcium, albumin, total protein, and inorganic phosphate. The ionized calciu...

pure submandibular saliva was collected from anaesthetized vitamin - a - treated and control rats with using of pilocarpine as secretogogue, and then the serum was collected by cardiac puncutre. intraperitoneal injection of a large single dose (100,000 iu/kg) of vitamin a changed total protein, calcium and sodium concentrations of saliva so that sodium level of submandibular saliva was reduced ...

We recently reported a significant positive association in the National Health and Nutrition Examination Survey between high levels of total calcium in serum, measured prospectively, and risk of fatal prostate cancer. To confirm this, we examined associations between total and ionized serum calcium and prostate cancer mortality in an independent cohort, the Third National Health and Nutrition E...

BACKGROUND 1) To evaluate calcium absorption in infants fed a formula containing prebiotics (PF) and one without prebiotics (CF). 2) To compare calcium absorption from these formulas with a group of human milk-fed (HM) infants. METHODS A dual tracer stable isotope method was used to assess calcium absorption in infants exclusively fed CF (n = 30), PF (n = 25) or HM (n = 19). Analysis of varia...

BACKGROUND Calcium is known to be major mediator in ischemic neuronal cell death. Recent studies have shown that elevated serum calcium levels at admission in patients with stroke have been associated with less severe clinical deficits and with better outcomes. AIM The aim of this to determine the correlation between serum calcium (total, corrected, and ionized) and infarct size (IS) in patie...

The effects of verapamil (1 mg/liter, 2 x 10(-6) mol/liter), quiescence, and cardioplegia (K+ 16 mmol/liter, Mg2+ 16 mmol/liter) on calcium exchange and mechanical function during ischemia and reperfusion have been investigated in the rabbit interventricular septum at 32 degrees C. Calcium influx and efflux were recorded continuously with 47Ca2+ and 45Ca2+. After 60 minutes of total ischemia an...
