Abstract
In rats raised on an arsenite-added milk diet, the content of arsenite in brain did not increase in either the whole organ or the organ per g, even when the amount of added arsenite was increased to more than 550 ppm. The content of arsenite in kidney also did not increase in the whole organ, even with more than 200 ppm. The content in liver and spleen however increased in parallel with the amount of added arsenite in both preparations. On the other hand, in rats raised on an arsenite-added cereal diet, the content of arsenite in brain, liver and spleen increased in parallel with the amount of added arsenite in both whole organ and organ per g, but in kidney there was no increase in the whole organ, even when the amount of added arsenite was increased to more than 200 ppm.
