Angiogenic Potential of 3-Nitro-4-Hydroxy Benzene Arsonic Acid (Roxarsone)
BACKGROUND Roxarsone (3-nitro-4-hydroxy benzene arsonic acid) is an arsenic compound widely used in the poultry industry as a feed additive to prevent coccidiosis, stimulate growth, and to improve tissue pigmentation. Little is known about the potential human health effects from roxarsone released into the environment from chicken waste or from residual compound in chicken products. OBJECTIVE...
متن کاملTHERAPEUTIC ACTION OF N-PHENYLGLYCINEAMIDE-p-ARSONIC ACID (TRYPARSAMIDE) UPON EXPERIMENTAL INFECTIONS OF TRYPANOSOMA RHODESIENSE
A series of experiments was carried out to determine the effects of tryparsamide upon the infections produced in various species of animals by Tr. rhodesiense. The strain of trypanosome used was one which possessed a very low virulence for guinea pigs, was fairly virulent for mice and rats, and highly virulent for rabbits. Therapeutic experiments carried out on 24 hour infections in mice and ra...
متن کاملThe Quality of Indian-Made Synthetic Drugs—I. Examination of P-Carbamido-Phenyl-Arsonic Acid (Carbarsone) of Indian Manufacture
on foreign sources, chiefly Germany, for the supply of almost all her requirements in this direction. This was strikingly manifested by the precipitous rise in prices immediately after the declaration of war against Germany in 1939. Since then the shortage of German-made and other imported synthetics has caused two important results : (1) Indian physicians are gradually showing an increasing co...
متن کاملBiotransformation of 3-nitro-4-hydroxybenzene arsonic acid (roxarsone) and release of inorganic arsenic by Clostridium species.
The extensive use of 3-nitro-4-hydroxybenzene arsonic acid (roxarsone) in the production of broiler chickens can lead to increased soil arsenic concentration and arsenic contaminated dust. While roxarsone is the dominant arsenic species in fresh litter, inorganic As (V) predominates in composted litter. Microbial activity has been implicated as the cause, but neither the specific processes nor ...
متن کامل2-Aminoethylarsonic acid as an analogue of ethanolamine phosphate. Endowment of ethanolamine-phosphate cytidylyltransferase with CTP pyrophosphatase activity.
2-Aminoethylarsonic acid was tested for its ability to act as a substrate for ethanolamine-phosphate cytidylytransferase as a cytidylyl acceptor in place of ethanolamine phosphate. The expected product, like all mixed anhydrides of arsonic acids, should hydrolyse spontaneously with regeneration of the substrate analogue and CMP formation; such CMP production was observed. The limiting velocity ...
