Recently, Major R. N. Chopra, i.m.s., Pro| fessor of Pharmacology at the Calcutta School ; of Tropical Medicine, whilst carrying out some j pharmacological experiments with antimony ; compounds, noticed that when the serum from a kala-azar patient was added to certain of the pentavalent compounds of antimony a heavy precipitate was formed. He found that this precipitate was not formed if normal...

Antimony compounds are the cornerstone treatments for tegumentary leishmaniasis. The reactivation of herpes virus is a side effect described in few reports. We conducted an observational study to describe the incidence of herpes zoster reactivation during treatment with antimony compounds. The global incidence of herpes zoster is approximately 2.5 cases per 1,000 persons per month (or 30 cases ...

It is very important to investigate antimony geochemical behavior in order to identify its source, or reveal contamination processes, since antimony and its compounds are considered to be pollutants of high priority by the Environmental Protection Agency of the United States (USEPA). However, the concentration of antimony in most geological samples is very low, and its stable isotope mass diffe...

The ability of antimony and antimony-containing parasiticidal agents to enhance the rate of heme degradation in liver and kidney was investigated. Trivalent antimony was shown to be an extremely potent inducer of heme oxygenase, the initial and rate-limiting enzyme in heme degradation, in both organs, whereas the pentavalent form was a weak inducer of this enzyme. The ability of antimony to ind...

In the Indian Medical Gazette for June 1927, Chopra, Gupta, and David described a new serum test for kala-azar. These workers observed that when certain organic compounds of antimony were brought in contact with the serum from kala-azar patients in a miniature testtube, a thick flocculent precipitate was formed at the junction of the two; whereas with nonkala-azar sera no such precipitation occ...

Antimony(V) and bismuth(V) complexes of lapachol have been synthesized by the reaction of Ph₃SbCl₂ or Ph₃BiCl₂ with lapachol (Lp) and characterized by several physicochemical techniques such as IR, and NMR spectroscopy and X-ray crystallography. The compounds contain six-coordinated antimony and bismuth atoms. The antimony(V) complex is a monomeric derivative, (Lp)(Ph₃Sb)OH, and the bismuth(V) ...

A kinetic model for flame inhibition by antimony-halogen compounds in hydrocarbon flames is developed. Thermodynamic data for the relevant species are assembled from the literature, and calculations are performed for a large set of additional species of Sb-Br-C-H-O system. The main Sb- and Br-containing species in the combustion products and reaction zone are determined using flame equilibrium ...

The single crystals of the new isostructural compounds Sb3O4F and Y0.5Sb2.5O4F and the two previously known compounds M-SbOF and α-Sb3O2F5 were successfully grown by a hydrothermal technique at 230 °C. The new compound Sb3O4F crystallizes in the monoclinic space group P21/c; a = 5.6107(5) Å, b = 4.6847(5) Å, c = 20.2256(18) Å, β = 94.145(8)°, z = 4. The replacing part of Sb with Y means a sligh...
