The effects of p-chloromercuribenzoic acid and chloromercuribenzene-p-sulphonic acid on pancreatic islets were studied in vitro. Obese-hyperglycaemic mice were used as the source of microdissected islets containing more than 90% beta-cells. p-Chloromercuribenzoic acid and chloromercuribenzene-p-sulphonic acid stimulated insulin release at concentrations of 0.01mm or above. This stimulation was ...

Core-shell AlOOH-polyglycol (APG) was synthesized by refluxing polyglycol with AlOOH nanoparticles in toluene in the presence of p-toluene sulphonic acid. The effects of solvent amount on the core-shell structure have been investigated. The morphology and thermal stability of the products were characterized by means of transmission electron microscopy (TEM) and thermogravimetric analysis (TGA)....

Various polymer coatings have been investigated for the protection of mercury thin-film electrodes in the square wave anodic stripping voltammetry of environmental samples using batch injection analysis, with injection of untreated samples of volume 50 ml directly over the sensing electrode. Polymer coatings studied include those with controlled porosity, and cation-exchange polymers based on s...

Urinary and faecal excretion of radioactivity after either an intravenous or oral (1 mg/kg) dose of 35S-labelled Tobias acid (2-naphthylamino, 1-sulphonic acid), a dyestuff intermediate structurally similar to the powerful carcinogen 2-naphthylamine, was studied in rats. The Tobias acid was eliminated from the body within 24 hours of administration, almost exclusively through the urine. TLC-chr...

BACKGROUND Growing evidence suggests that intestinal recovery from injury induced by radiation, endotoxin, and protein deficiency is improved by the ingestion of nucleosides and nucleotides. AIM This study examined the effect of dietary nucleosides and nucleotides supplementation on trinitrobenzene sulphonic acid induced colonic damage in experimental colitis. METHODS Sprague-Dawley rats we...
