| Abstract |
A revised protocol for the exfoliated cell micronucleus assay was field-tested in a population exposed to a genotoxic agent at levels associated with a significant increase in cancer risk. The standard assay involves microscope examination of epithelial smears to determine the prevalence of micronucleated cells with separate scoring of other nuclear anomalies associated with cytotoxicity and genotoxicity. Prevalence of micronucleated cells was elevated in the snuff users compared to the non-users. The pattern of relative frequencies of several nuclear anomalies provided strong evidence of a cytotoxic effect of snuff. |
