Note s biphenol failed to induce SSBs in the Chinese hasster cells . The SSBs was detected in<br />

the -Chinesa _44nAfte-cells after the treatment of hydroquinone <strong>and</strong> peroxidase<br />

simultaneously . These results suggest that the Induction of ∎icronuclei by benzene<br />

follows after SSBs, <strong>and</strong> the several metabolites play an important role to Induce<br />

micronuclei <strong>and</strong> myelotoxicity through localized setaboliss within the bone marro . such<br />

as peroxidase-aediated metaboliss .<br />

This study investigated the relationship of sister chromatid exchanges (SCE)<br />

539<br />

frequency between normal <strong>and</strong> Downs syndrome infants ^nd their parents .•Blood .lymphocytes<br />

from 12 infants (3 females <strong>and</strong> 9 males) with Down's s'mdrome were cultured in RPHI-1640<br />

medium containing 10 ug/ml of brocodeoxyuridine for 63h . The mean frequency of SCE per<br />

metaphase for the patients (both sexes) was 9 .220 .8 which was significantly higher<br />
