CYANOGUANIDINE<br />
5. TOXICITY ID: <strong>461</strong>-<strong>58</strong>-5<br />
DATE: 25.02.2004<br />
Method : other<br />
Year : 1985<br />
GLP : yes<br />
Test substance : other TS<br />
Remark : The result essentially is not influence of dicyandiamide.<br />
Result : Without metabolic activation: Statistically significant increases in sister<br />
exchanges were observed at 333 nL/mL and 1.0 uL/mL with a dose<br />
response established observed the test article is considered positive in the<br />
sister chromatid exchange assay under of non-metabolic activation.<br />
With metabolic activation: There were statistically significant increases in<br />
sister exchanges were observed at 3.3 uL/mL and 10.0 uL/mL with a dose<br />
response established. The test article is considered positive under the<br />
condition of metabolic activation in the sister chromatid exchange assay.<br />
Test condition : Metabolic activation system: S-9 from male Sprague-Dawley induced<br />
Aroclor 1254, S-9 15 uL/mL of S-9 mix<br />
Controls:<br />
Negative control; McCoy's 5a medium<br />
Solvent control; DMSO<br />
Positive control; Mitomycin C<br />
Test substance : Dicyandiamide was one component of a rigidite.<br />
The rigidite was used in this test.<br />
Reliability : (4) not assignable<br />
