Analytical approaches to the study of the disposition of myelotoxic agents.
A correlation of myelotoxic effect with concentration or a foreign compound of its metabolite at the site of action may provide useful insights into the mechanism of toxic action and/or its amelioration. This correlation requires sensitive and specific assay methods. This communication describes useful methods for the study of benzene disposition in rodents. The assays are sensitive, specific, and rapid. They rely on gas chromatography-mass spectrometry and on high performance liquid chromatography. These methods have allowed measurement of catechol, phenol, and hydroquinone in samples of rodent bone marrow following inhalation exposure to benzene. Their application to the study of benzene metabolism in rat bone marrow in situ is also described.
