Mercury distribution in mouse brain after i.v. administration of bis(methylmercuric) selenide.

The distribution of mercury in the brain of mice after i.v. administration of methylmercury, methylmercury with selenite, or bis(methylmercuric) selenide (BMS) was examined by whole-body autoradiography using 203Hg-labelled mercury compounds. The radioactivity in the brain of the mice that received methylmercury and selenite simultaneously, or BMS, was higher than that of the mice that received methylmercury alone, but the differences were not significant.
