Complex of bismuth, an anti-inflammatory drug, was studied by EPR spectroscopy. The aim of this study was to determine concentrations and properties of free radicals formed during thermal sterilization of bismuth subgallate according to pharmacopoeia norms to optimize its sterilization process. Different temperatures (160°C, 170°C, and 180°C) and times (120 minutes, 60 minutes, and 30 minutes) ...

: Bismuth compounds have been used extensively as medicines and in particular for the treatment of gastrointestinal ailments. In addition to bismuth's well known gastroprotective effects and efficacy in treating H. pylori infection it also has broad anti-microbial, anti-leishmanial and anti-cancer properties. Aspects of the biological chemistry of bismuth are discussed and biomolecular targets ...

Evidence is presented to show that bismuth combines in vitro with the phosphate of nucleic acids in a manner similar to its reaction with inorganic phosphate. When tested under similar conditions, protein exhibited no attraction for bismuth. The results of the in vitro experiments, which are of interest within themselves, may be indirectly applicable to in vivo staining. Dividing cells of onion...

Objective(S): The dangerous effects of X-ray have been elucidated by scientific studies in occupational health hygiene.  X-ray protective like an apron, thyroid shield and gloves have been made of lead (Pb) to protect against X-ray. However, such equipment makes a lot of safety and health problems such as toxicity, weight, inflexibility and troubles usage in a physician. To ove...

This study investigated the effect of colloidal bismuth subcitrate and cimetidine on Campylobacter pylori in peptic disease. In 74% of 135 patients with peptic disease diagnosed at endoscopy C pylori was detected before treatment. Compared with cimetidine, colloidal bismuth subcitrate significantly decreased the incidence of C pylori after six weeks of treatment (p less than 0.001). In the coll...

Effect of Bismuth Doping on the Magnetic Properties of Rare-Earth Orthoferrites by Kelsey A. Collier The purpose of this experiment was to investigate the magnetic properties of bismuth-doped rare-earth orthoferrites, prompted by scientific interest in and the possible device applications of multiferroics. The magnetic susceptibility of single-crystal samples of pure and bismuth-doped orthoferr...

Introduction: The effects of X-rays on carcinogens have been proven in recent years. Today, lead is used in many devices such as lead covers, thyroid protectors to protect the body against x-rays. But this equipment contains many disadvantages such as, Toxicity, High weight and Lack of flexibility. Today, newer methods, such as semi-solid skin care products (cream, ointment), a...

a bacteriological investigation performed on the biopsies of 1 30 patients with gastrointestinal disorders at the gi section of imam khomeini hospital concluded in the isolation of 100 cases of helicobacler pylori. the antibacterial effects of bismuth salts alone and in synergy with tetracycline and metronidazole were evaluated on the basis of disc diffusion method on 5 randomly selected pure c...

A differential pulse polarographic method is proposed for the trace determination of bismuth and copper from large volumes of aqueous samples after adsorption of their 1-(2-thiazolylazo)-2-naphthol complexes onto microcrystalline naphthalene in the pH ranges of 7.2-9.0 and 4.0-7.8, respectively. Bismuth and copper are desorbed from microcrystalline naphthalene with 9 mL 1M HCl. Well-defined pea...
