Leukocyte response in young mice chronically exposed to fluoride.

Greenberg SR.

ABSTRACT: A light and fluorescent microscopy study of sternal and femoral bone marrow, taken from young Swiss mice exposed for up to 280 days to elevated levels of NaF in drinking water, revealed morphologic abnormalities in cell structure and mitotic figure formation in immature leukocytes. Alterations in the content and distribution of RNA and DNA also appeared after several weeks of exposure. These findings, interpreted in relation to other reported data, were compatible with a possible shift of these cells toward anaplasia.
