Test condition : This study is part of a International Collaborative Program, published as:<br />

Evaluation of Short-Term Tests for Cancerogens Progress in Mutation<br />

Research Vol 1. Edited by Frederick J. Serres and John Ashby, 1981<br />

CHEMICALS:<br />

42 coded chemicals were investigated in short-term tests for<br />

cancerogenicity in different laboratories<br />

It should be suggested that only 100%-pure chemicals should be used<br />

when evaluating a test system.<br />

In the present work the compound with code no 41 is declared as otoluidine<br />

hydrochloride, whereas in an the overall summary of this program<br />

code no. 41 is declared as o-toluidine.<br />

In the first phase mice were injected intraperitoneally with 80% of the LD50<br />

dose at 0 and 24h, and samples were taken at 48, 72, and 96 hours. While<br />

there was no increase in micronuclei the test substance were retestet with<br />

one injection of 100 and 50 % of the LD50 dose, and samples were taken<br />

at 30, 48 and 72 hours.<br />

Reliability : (4) not assignable<br />

Method-Evaluation, no specific data on given doses<br />
