Plasma calcium and phosphate concentrations and alkaline phosphatase activities were examined retrospectively in 50 patients with histologically proven osteomalacia and 50 age- and sex-matched control subjects with normal bone histology. An abnormal plasma alkaline phosphatase activity was more useful than an abnormal plasma calcium or phosphate concentration in distinguishing between normal an...

results the mean levels of serum calcium, serum zinc, cerebrospinal fluid calcium and cerebrospinal fluid zinc were 14.51 ± 3.69 mg/dl; 184.04 ± 65.49 µg/dl; 5.23 ± 2.21 mg/dl and 87.06 ± 28.25 µg/dl respectively. conclusions we did not find any clear abnormality in plasma or cerebrospinal fluid calcium and zinc levels in children with febrile seizures in our patient population. patients and me...

Angiotensin II and extracellular potassium stimulate aldosterone production in adrenal glomerulosa cells by mobilizing the calcium messenger system. This response requires calcium influx across the plasma membrane, followed by calcium uptake into the mitochondria. It has been proposed that calcium is transported to the mitochondria via the lumen of the endoplasmic reticulum, acting as a kind of...

The effect of calcium chloride (4.0 mg Ca2+/100 g BW) on the calcium metabolism in the hepatic bile system was investigated in intact and thyroparathyroidectomized rats. The administration of calcium did not alter the serum calcium of intact rats but increased it markedly in thyroparathyroidectomized rats. The administration of calcium to intact rats also caused a significant decrease in the li...

Background: Jaundice is one of the most common problems occurring in the neonatal period. It is commonly managed by phototherapy with its inherent complications. However, this treatment modality may itself result in the development of hypocalcaemia and create serious complications including convulsion and related conditions. Objective: To determine the effect of phototherapy on serum calcium le...
