Histochemical characterization of the lead intranuclear inclusion bodies.
A battery of histological and histochemical techniques was applied on the lead intranuclear bodies that have resuted in the kidneys of adult Wistar male rats receiving lead acetate in their diet to determine their nature. The intranuclear inclusion bodies have stained strongly with xanthene, anthraquinone, and trisulfonated basophilic dyes and weakly with dyes containing both positive and negative radicals, and they have responded negatively to acidophilic cationic dyes. They have also reacted positively to proteins and lead stains, but weakly to lipid stains, and negatively to Feulgen and methyl green pyronin techniques. The intranuclear bodies proved to be lead lipoprotein complexes containing sulfyhydryl groups and are basic in nature with orthochromatic, eosinophilic, argyrophilic, osmophilic, fuchsinophilic, and sudanophilic characteristics.
