Physical and chemical stability of suppositories containing aminophylline and various bases prepared in our hospital pharmacy was investigated. Ethylenediamine in aminophylline decreased, the melting points of the suppositories rose, and the disintegration and liquefaction times were prolonged in suppositories with Witepsol base when stored at room temperature. Thin-layer chromatography produce...

The potential of various chemically modified rice husk to remove Methylene Blue (MB) and Reactive Orange 16 (RO16) from aqueous solution was investigated. It was found that ethylenediamine tetraacetic acid modified rice husk (ERH) has the highest adsorption capacity for both MB and RO16. ERH was produced by treating natural rice husk (NRH) with 0.5 g of ethylenediamine tetraacetic acid (EDTA) i...

BACKGROUND Atherosclerotic renovascular disease is increasingly recognized as an important cause of renal failure in patients over 60 years of age but the processes leading to renal dysfunction have not been defined. We have examined the relationship between renal artery stenosis and individual renal function in patients with atherosclerotic renal artery stenosis. METHODS In this prospective ...

We report on the fabrication of covalently crosslinked and amine-reactive hollow microcapsules using 'reactive' layer-by-layer assembly to deposit thin polymer films on sacrificial microparticle templates. Our approach is based on the alternating deposition of layers of a synthetic polyamine and a polymer containing reactive azlactone functionality. Multilayered films composed of branched poly(...

Experimental Reagents and chemicals m-Phenylenediamine (mPDA >99%) was purchased from Acros Organics, ethylenediamine (EDA, Sigma Ultra) was obtained from Sigma Aldrich. ortho-Phosphoric acid (85%, ACS certified) was purchased from Fisher Scientific. All the other chemicals were of analytical grade. Buffer solutions with different pH were prepared using chemicals (such as sulphuric acid, citric...

Eleven Vibrio vulnificus (lactose-positive vibrio) strains were less susceptible to the bactericidal activity of normal human serum or serum treated with magnesium-ethyleneglycol-bis (beta-aminoethyl ether)-N,N'-tetraacetic acid than were six Vibrio parahaemolyticus strains.

The new complex of [H2en][Cu(pydc)2].2H2O (1) (where H2en and pydc are ethylenediammonium and 2,6-pyridinedicarboxylate, respectively) was synthesized by the reaction of a mixture of ethylenediamine (en) and 2,6-pyridinedicarboxylic acid (H2pydc) in a mixture of CH3OH/H2O as solvent. This complex was fully characterized by elemental analysis, IR, UV–Vis spectroscopy as well as single-crystal X-...
