Part of the northern Palatinate region in Germany is characterized by elevated levels of arsenic and antimony in the soil due to the presence of ore sources and former mining activities. In a biomonitoring study, 218 residents were investigated for a putative increased intake of these elements. Seventy-six nonexposed subjects in a rural region in south lower Saxony were chosen as the reference ...

Toward developing antileishmanial agents with mode of action targeted to DNA topoisomerases of Leishmania donovani, we have synthesized a large number of derivatives of betulin. The compound, a natural triterpene isolated from the cork layer of Betula spp. plants exhibits several pharmacological properties. Three compounds (disuccinyl betulin, diglutaryl dihydrobetulin, and disuccinyl dihydrobe...

A few months ago we refused to publish in this journal an advertisement of an antimony preparation which was said to be a specific remedy for malaria in all forms. This preparation appeared to be an ordinary pentavalent one. In our present number we publish an article by P. C. Sen Gupta on malaria complicating kala-azar, in which it is recorded that malaria may occur during or immediately after...

A method for rapid and accurate determination of trace quantities of SbIII was developed based on its inhibitory effect on the decolorizing reaction of methyl orange in the presence of bromate and bromide ions in acidic media. Decolorization of methyl orange by the reaction products was used to monitor the reaction spectrophotometrically at 525 nm. The method allows determination of antimony in...

Introduction.?The senior writer, Burke (1943), made an appeal for an efficient successor to neostibosan (Bayer), this, preferably, to be a British product. What seems to be an almost perfect answer to that appeal?and indeed a British product?is the preparation stibatin (Glaxo Laboratories), or sodium antimony gluconate (antimony v-hexonate), a crystal-clear sterile solution containing 20 mg. of...

This work report on the structural and electrical characteristics of zinc oxide single crystal samples doped with antimony. Doping was carried out by antimony thermal diffusion at 1000 °C for periods of one and two hours under nitrogen environment from a solid source formed by antimony oxide. X-ray diffraction was used to determine the crystalline phases in samples and the structural change owi...
