THE chief difficulties in the benzidine method for determination of sulphate arise in obtaining the conditions requisite for maximum precipitation of benzidine sulphate. Most investigators have drawn attention to the importance of adjusting the acidity of the solution, while some of them have studied the interference known to be caused by certain ions: chlorides, for example, may increase the s...

1. Lipoprotein lipase (EC 3.1.1.34), which was previously shown to bind to immobilized heparin, was now found to bind also to heparan sulphate and dermatan sulphate and to some extent to chondroitin sulphate. 2. The relative binding affinities were compared by determining (a) the concentration of NaCl required to release the enzyme from polysaccharide-substituted Sepharose; (b) the concentratio...

BACKGROUND Regional anesthesia is widely used to perform different surgical procedures including those performed on the extremities. In this study, the anesthetic effects of adding intrathecal neostigmine or magnesium sulphate to bupivacaine in patients under lower extremities surgeries were assessed. MATERIALS AND METHODS In this double-blind randomized clinical trial, 90 patients, candidate...

beta-N-Acetylhexosaminidase from boar epididymis was separated into two forms, A and B, on DEAE-cellulose. Both these forms were excluded from Sepharose S-200 and had apparent Mr values of 510 000 on gradient gel electrophoresis under non-denaturing conditions. Affinity chromatography on 2-acetamido-N-(6-aminohexanoyl)-2-deoxy-beta-D-glucopyranosylam ine coupled to CNBr-activated Sepharose 4B w...

Recent studies of the chemical structure of glycolipids (Klenk and Gielen, 1961, 1963; Svennerholm and Raal, 1961; Kuhn, 1961; Wolfe and Lowden, 1964) have contributed to our knowledge of the metabolism of different glycolipids. Thus, a low concentration of 3-glucosidase in human brain and other organs will give rise to a blocked degradation of gangliosides, with accumulation of glucocerebrosid...

Several cases of aerosol plumes resulting from trans-Pacific transport were observed between 2 km and 5.3 km at Whistler, BC from 22 April 2006 to 15 May 2006. The fine particle (<1μm) chemical composition of most of the plumes was dominated by sulphate that ranged from 1–5μg m−3 as measured with a Quadrapole Aerosol Mass Spectrometer (Q-AMS). Coarse particles (>1μm) were enhanced in all sulpha...

BACKGROUND The relatively little resistance to quinine globally has led to an increase in its use in P. falciparum malaria especially in multi-drug resistant strains. OBJECTIVE To evaluate the physicochemical and equivalency of three brands of quinine sulphate tablets available in South Western region of Nigeria. METHODS The pharmaceutical and chemical equivalence of three brands of quinine...
