A liquid chromatographic (LC) method was developed for the determination of allantoin, uric acid, and indoxyl sulfate in mammalian urine contaminated packaging material including paper bagging, corrugated cardboard, grayboard, and burlap bagging. The procedure involves solvent extraction and isolation of the 3 analytes by reversed-phase LC with ultraviolet detection at 225 nm for allantoin and ...
BACKGROUND Neurotoxicity and pulmonary dysfunction are well-recognized problems associated with prolonged human exposure to high concentrations of airborne manganese. Surprisingly, histological characterization of pulmonary responses induced by manganese remains incomplete. The primary objective of this study was to characterize histologic changes in the monkey respiratory tract following manga...
Co-application of Aspergillus niger (A. niger) and phosphate rocks (PR) has been practiced by environmentalists for lead (Pb) remediation. The secretion organic acid A. usually dominates the dissolution PR Pb immobilization. In this study, two types (fluorapatite (FAp) phosphogypsum (PG)) were investigated in remediation under three different forms nitrogen (ammonium, nitrate, urea). Our result...
The in vitro and in vivo effects of some drugs on rat erythrocytes 6-phosphogluconate dehydrogenase were investigated in this study. Rat erythrocyte 6-phosphogluconate dehydrogenase was partially purified with ammonium sulfate precipitation. The enzyme activity was determined by Beutler's method. Some drugs such as ampicillin, amikacin sulfate, and netilmicin sulfate inhibited the enzyme activi...
The administration of vitamin A to vitamin A-deficient rats resulted in a decreased concentration of inorganic sulfate-sulfur in the serum from a value of 2.5 mg. per cent to 1.8 mg. per cent, the latter being close to the value of 2.0 mg. per cent found in normal rats of the same age. The uptake of sulfate and phosphate by femurs and tibiae of vitamin A-deficient rats was less than that in nor...
CONTEXT Postoperative sore throat (POST) is a complication that is unresolved in patients undergoing endotracheal intubation. AIM To compare the effects of ketamine and magnesium sulfate nebulizations in two strengths, on the incidence and severity of POST, hoarseness, and cough. SETTINGS AND DESIGN Sixty surgical patients undergoing elective abdominal and lower limb surgeries under combine...
The concentration of inorganic sulfate-sulfur in the serum of vitamin D-deficient rats, 2.6 to 3.5 mg. per cent, was found to be higher than that in the serum of normal rats of the same age, 2.0 mg. per cent. No change was observed following the administration of 25 gamma of vitamin D(2). In accord with the results of others, it was found that a definitely increased deposition of phosphorus in ...
Nonsteroidal anti-inflammatory drugs (NSAIDs) increase sulfate renal clearance and decrease the fractional reabsorption of sulfate by the kidneys. The mechanism of this alteration of inorganic sulfate homeostasis is unknown. The objectives of this study were 1) to investigate if sulfate renal transport is altered in isolated membrane vesicles after pretreatment of animals in vivo with ibuprofen...
Anaerobic biodegradation of phenanthrene (PHE) was investigated using an enrichment culture consists predominantly of sulfate-reducing bacteria (87+/-6%). Aqueous biodegradation experiments were designed using the rotatable central composite design with five levels. The designed concentrations were 2-50 mg L(-1) for PHE, 480-3360 mg L(-1) for sulfate, and 5-50 mg L(-1) for initial biomass. Expe...
based on a number of studies, magnesium sulfate (mgso4) given after a diffuse axonal injury has gained attention as a useful neuroprotective agent .the present study was conducted to examine if magnesium sulfate has a therapeutic efficacy and safety in patients with a severe diffuse axonal injury. adult patients admitted within 1 hour of a closed traumatic brain injury (tbi) with a severe diffu...
