Abstract
The response to lead nitrate has been assessed in two cell lines of renal origin. The range of toxic concentrations was determined by Neutral Red assay after 24-h of exposure. Morphological changes in the Buffalo Green Monkey (BGM) and VERO cell lines after exposure to subcytotoxic doses (1.38 mM and 1.04 mM, respectively) equivalent to EC10 (effective concentrations 10%) of lead nitrate were evaluated at the ultrastructural level by transmission microscopy. The most notable finding in treated cells was the presence of inclusion bodies in the form of irregular granules of varying size in both cytoplasm and lysosomes. Cell membrane integrity was not affected. The number of phagolysosomes and myeline figures associated to the inclusion bodies was higher than in the control cultures. We conclude that the phagolysosomic mechanism fails to digest this metal ion and the BGM and VERO renal cell lines can be considered as useful tools for toxicological studies involving lead nitrate.
