malformation.<br />

parameters <strong>and</strong> median conc. ranged from<br />

0.72 - 1.44 with an average <strong>of</strong> 0.99.<br />

malformation did not change but the<br />

entire curve was shifted to lower conc.<br />

throughout the course <strong>of</strong> the experiment.<br />

The greater shift occurred between 24<br />

<strong>and</strong> 48 h into the experiment.<br />

hydroxyurea 0.3 mg/mL Hydroxyurea alone caused 20.6 %<br />

malformation. Coadministration with<br />

caffeine or theophylline greatly increased<br />

the incidence <strong>of</strong> malformed embryos<br />

(89% <strong>and</strong> 50.6%, respectively) <strong>and</strong><br />

mortality (6.9% <strong>and</strong> 8.1%, respectively).<br />
