BACKGROUND
Extracellular pyrophosphate is a potent endogenous inhibitor of vascular calcification, which is degraded by alkaline phosphatase (ALP) and generated by hydrolysis of ATP via ectonucleotide pyrophosphatase/phosphodiesterase 1 (eNPP1). ALP activity (as routinely measured in clinical
The investigation was carried out on 12 cows and their calves. At the time of 3 months before parturition and 7 days after parturition metabolic alkalosis one provoked with the high protein feed. The laboratory investigations dependent of determinations on the rumen content the pH, NH3, volatile
The expression of c-jun, mitogen-activated protein kinase phosphatase-1 (mkp-1), caspase-3 and glial fibrillary acidic protein (gfap) was examined at 1, 3 and 7 days after cortical cold injury in rats by in situ hybridisation and immunocytochemistry. Alterations of gene expression were related to
Topiramate (TPM) is an anticonvulsant whose impact on firing activity and intracellular pH (pHi) regulation of CA3 neurons was investigated. Using the 4-aminopyridine-treated hippocampal slice model bathed in bicarbonate-buffered solution, TPM (25-50 microm) reduced the frequency of epileptiform
Substantial fluid shifts occur during liposuction as wetting solution is infiltrated subcutaneously and fat is evacuated, causing potential electrolyte imbalances. In the porcine model for large-volume liposuction, plasma aspartate aminotransferase and alanine transaminase levels were elevated
Experiments were done on rats to investigate the nature of the renal response to metabolic acidosis and the changes in enzyme activity associated with increased ammoniagenesis. When metabolic acidosis was induced with oral feeding of ammonium chloride for 48 hr, there was an increase of activity of
Serum electrolytes, metabolites and enzymes were determined in arterial blood of chronically cannulated dogs at room temperature and on exposure to 44-50 degrees C. These dogs were naturally acclimated to hot, arid conditions. In dogs maintaining their rectal temperatures (TR) below 40 degrees C, no
BACKGROUND
Hypercalcemia of immobilization, while rare, may occur in adolescent boys after fracture. Although not fully understood, the mechanism appears to be related to bone turnover uncoupling, in part mediated by upregulation of RANKL. Animal studies suggest that parathyroidectomy suppresses
Objectives: To assess the effects of zinc pretreatment on hepatorenal toxicity following chronic exposure to glyphosate-based herbicides in male rats.
Methods: Following zinc
In male patients with idiopathic recurrent calcium urolithiasis (RCU) the effects of oral potassium sodium citrate (PSC) on acid-base, citrate and mineral metabolism were investigated. There were 17 normocitraturic and 15 hypocitraturic patients. The examination time points in our clinical
In a 10-year-old castrated male shorthaired German pointer polyuria was associated with slight hypokalemia, hypophosphatemia and alkalosis, as well as elevated plasma concentrations of a glucocorticoid-inducible iso-enzyme of alkaline phosphatase. Repeated measurements of urinary corticoids and
In rats exposed for 12 weeks to the mixture of nitric oxides (0.34--2.81 mg/m3) and chlorine (0.61--1.50 mg/m3) the following changes were found: increased methemoglobin concentration (MetHb), increased partial pressure, increased total carbon dioxide concentration (pCO2 TCO2), increased current
Bartter's syndrome is characterized by hypochloremia, hypokalemia, metabolic alkalosis associated with renal potassium leakage, and normal blood pressure despite increased plasma renin activity. Although association of empty sella with Gitelman syndrome has been reported, no association has been
Several disturbances of acid-base balance, including chronic metabolic and respiratory acidoses and metabolic alkalosis, are associated with enhanced proximal tubule bicarbonate reabsorption. To determine whether augmented brush border Na/H exchange might mediate enhanced proximal tubule bicarbonate
In rats exposed to odourless kerosene of 75 and 300 mg/m3 concentration, for 14 weeks, morphologic and cytoenzymatic examinations of lungs have been carried out and acid-base equilibrium indices in blood have been determined. Passive congestion of lung parenchyma, subpleural blood extravasation,
