title: Flow cytometry Coulter volume analysis of lead- and cadmium-induced cellular alterations in bone marrow obtained from young adult and aged Balb/c mice.
abstract: Flow cytometry Coulter volume analysis was used to examine the effects of an acute exposure to cadmium or lead on subpopulations of Balb/c bone marrow cells. A significant shift in the volume of Balb/c bone marrow cells was detected in response to a single i.p. injection of cadmium acetate (Cd) or lead acetate (Pb) compared to sodium acetate (Na)-treated mice. An increase in the relative number or size of myeloid/monocytic cells was noted in the bone marrow of cadmium or lead-treated mice. This effect was more pronounced in aged Balb/c mice than in young adults. These studies suggest the flow cytometry Coulter volume analysis may be a useful and sensitive technique for the assessment of cellular changes that occur in the bone marrow in response to xenobiotic exposure.
