conclusions this study showed that magnesium sulphate added to sufentanil through pcia is an effective method to alleviate pain in patients undergoing lower limb orthopedic surgery. moreover, we found fewer side effects on magnesium-sufentanil regimen in terms of in nausea, vomiting, and sedation; and patients’ satisfaction in this regimen was more rather than that in the regiment of sufentanil...

A coagulation treatment is a separation technology widely used in industries as pre-treatment step to remove the dissolved organic matter wastewater. However, type of coagulant, optimized dose, and cost associated with various commercially employed coagulants must be investigated for oil gas produced water. In this study, five coagulants—ferric chloride, aluminum potassium sulphate, chitosan, s...

The simultaneous pyrolysis of coal with wood was experimentally found to allow reducing concentrations sulfur-containing substances in gases released. objective experimental studies is comparison the sulphate calcium and aluminum ash coal-wood mixtures after latter a dense “packing” aggregate particles these two fuels at few millimeters distance between particles. 3B-grade lignite, T-grade bitu...

Purified m beta-acrosin catalysed amidolysis of several p-nitroanilides with C-terminal arginine residues. Antithrombin III inhibited amidolysis catalysed by the enzyme. This effect of antithrombin III was potentiated by heparin, and to a modest extent by heparan sulphate, cellulose sulphate, dextran sulphate and xylan sulphate. De-N-sulphated heparin, de-N-sulphated N-acetylated heparin, hepar...

Although the changes in urinary glycosaminoglycans have been investigated in several endocrinopathies, no information was hitherto available on the content and composition of urinary glycosaminoglycans in hypothyroidism. Urinary glycosaminoglycans were therefore investigated in patients with hypothyroidism and in healthy subjects. The total daily excretion of urinary glycosaminoglycans was foun...

Dietary sulphate may affect colonic pathophysiology because sulphate availability determines in part the activity of sulphate reducing bacteria in the bowel. The main product of sulphate reducing bacterial oxidative metabolism, hydrogen sulphide, is potentially toxic. Although it is generally believed that the sulphate ion is poorly absorbed, there are no available data on how much sulphate rea...

Kinetic parameters (Km and kcat.) of the two major forms (A and B) and a minor form (C) of human liver N-acetylglucosamine-6-sulphate sulphatase [Freeman, Clements & Hopwood (1987) Biochem. J. 246, 347-354] were determined with a variety of substrates matching structural aspects of the physiological substrates in vivo, namely heparin, heparan sulphate and keratan sulphate. Enzyme activity is hi...
