Effect of tripanosomicide benznidazole (Rochagan ) on the biodistribution of sodium pertechnetate (Na99mTcO4) in Wistar rats. Brazilian Archives of Biology and Technology , v. 51, p. 175-180, 2008.

The radiopharmaceutical sodium pertechnetate (Na99mTcO4) is used to obtain diagnostic images of the stomach, thyroid, parathyroids, salivary glands, brain and in the study of esophageal reflux and blood flow. This study aimed at evaluating in vivo the influence of benznidazole treatment on the sodium pertechnetate biodistribution in Wistar rats. The percentage of radioactivity per gram (%ATI/g) of various organs (brain, heart, esophagus, stomach, small intestine, large intestine, spleen, liver, muscle and blood) was determined. Comparing the treated rats with the controls, we observed that sodium pertechnetate biodistribution did not change when administered to rats treated for thirty days with benznidazoleengAcesso AbertoAntiparasiteRadiopharmaceuticalTechnetium-99mBenznidazoleBiodistributionTrypanosoma cruziarticle
