| Abstract: | Abstract The dynamics of the brain distributions of Hg, Zn, Cu and Se in guinea pigs exposed to methylmercury and selenium were examined by X-ray fluorescence imaging utilizing synchrotron radiation. Male Hartley guinea pigs were administered methyl mercury chloride and/or sodium selenite every day for ten days (s.c. 3mg as Hg/kg/day, mole ratio Hg:Se=1:1). Two dimensional distributions of Hg, Zn, Cu and Se in guinea pig brain were observed by nondestructive X-ray fluorescence imaging. Using the |
