Fifty nine patients with Helicobacter pylori positive duodenal ulcers that failed to heal after a six week course of treatment with H2 blockers were randomly assigned to one of the following three regimens: (i) bismuth subsalicylate, 600 mg three times daily (n = 19), (ii) ranitidine, 300 mg at night (n = 20), (iii) bismuth subsalicylate plus ranitidine (n = 20). Cumulative ulcer healing rates ...

Clostridium perfringens-associated necrotic enteritis causes significant economic losses. The objective of this study was to evaluate the effect of bismuth citrate, lactose, and organic acid on the development of necrotic enteritis in broilers. The first study was a dose response that evaluated bismuth citrate at 50, 100, or 200 ppm on bacterial intestinal colonization and lesion development as...

Three-dimension ordered macroporous (3D-OM) bismuth vanadates with a monoclinic crystal structure and high surface area (18-24 m(2) g(-1)) have been prepared using ascorbic acid (AA)- or citric acid (CA)-assisted poly(methyl methacrylate) (PMMA)-templating strategy with bismuth nitrate and ammonium metavanadate as the metal sources, HNO(3) as the pH adjuster and ethylene glycol and methanol as ...

Fifty nine patients with Helicobacter pylon positive duodenal ulcers that failed to heal after a six week course of treatment with H2 blockers were randomly assigned to one of the following three regimens: (i) bismuth subsalicylate, 600 mg three times daily (n=19), (ii) ranitidine, 300 mg at night (n=20), (iii) bismuth subsalicylate plus ranitidine (n=20). Cumulative ulcer healing rates after f...

Bismuth is a heavy metal and was regarded until recently to be the heaviest stable element. It was discovered around ten years ago that the only natural isotope of bismuth, 209Bi, is an alpha emitter with a halflife of 1.9 x 1019 years [1]. Due to the low stability in aqueous solutions of bismuth derivatives with the oxidation number +V, bismuth with the oxidation number +III is regarded as the...

biocl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (mw) assisted synthesis method for 23 minutes at 180 w. scanning electron microscopy (sem) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. the x-ray diffraction (xrd) pattern showed that a highly pure and crystalline phase has been obtained. the energy ...
