Inorganic cations have been localized in several animal and plant tissues by means of the pyroantimonate fixation procedure (1-3) . We demonstrated that an aqueous solution of potassium pyroantimonate enters the cell without disruption of cell membranes and produces electron-opaque cation-antimonate precipitates in a constant and reproducible manner. The results obtained in mouse testis (3) wer...

Several different types of burial were identified during the excavation Roman military cemetery associated with fort at Birdoswald, on Hadrian’s Wall (UK). Fragments glass vessels and beads recovered from many cremation deposits, as they commonly used rituals, these had been affected by heat. X-ray fluorescence spectroscopy scanning electron microscopy to investigate raw materials, colorants op...

lead antimonate yellow and lead-tin-antimony yellow) have been produced, starting from various recipes and from pure chemicals, in different experimental conditions. The products were analysed using micro-Raman spectroscopy. Differences in stoichiometric ratios, in melting temperatures and in crucible typologies were examined. Other analytical techniques were required to characterize the stoich...

Records were reviewed of 82 immunocompetent children (median age, 2. 5 years) from southern Greece who were diagnosed with visceral leishmaniasis from 1986 through 1998. Forty-nine (58%) patients originated from the city of Athens; of them, 46 (94%) lived by hills bordering the city. The median interval from the onset of symptoms to admission was 10 days. Fever and splenomegaly were observed in...

We determined the efficacy of the combination of the topical formulation 15% paromomycin sulfate/12% methylbenzethonium chloride (MBCL) and a short course (7 days) of parenteral meglumine antimonate (pentavalent antimony [Sb]) as treatment of American cutaneous leishmaniasis in Colombian patients. Patients were randomly assigned in unequal allocation (2:1:1:1) to group 1 (topical paromomycin/MB...
