2.0 - 2.4 1.07 - 1.2 1.7 - 1.8 Results from 3 trials. Rayburn et al. 1991b<br />

triethylene glycol 0, 1.7, 2.0% v/v 1.7% v/v TG only increased the mortality <strong>and</strong><br />

malformation with TCE. There were<br />

additive effects for growth for all<br />

solvents with the teratogens. EC25(96)<br />

tryptophan added had NAD+ levels<br />

similar to or higher than levels <strong>of</strong><br />

controls. Incidence <strong>and</strong> severity <strong>of</strong><br />

defects was not reduced <strong>and</strong> length <strong>and</strong><br />

mortality were unchanged. Protein<br />

content was not altered.<br />
