摘要
Mosl of anticancer drugs are mutagenic. A possible exeeption is diallyl .trisulfide(DAT ), a component of garlic. It is an antimutagenic anticunccr chemical although it ismainly uscd as antibiotic. Its modifying effeci on induction of UDS by mutagenicmitomycin C (MMC), cyclophosphamide (CP) and cis-diamine dichloroplatin (DDP) was invcstigiltcd with the UDS assay in the primary cultures of Wistar rat hepatocytes (hpc)using the autoradiographic technique. Resultsshowed that 1.0-4.0 nmol/ml of DAT didnot inducc UDS and that MMC, CP and DDP resulted in a significant induction ofdosc-dependent UDS. DAT enhanced induction of UDS by these drugs. A dose-effectrclationship was observed betwecn dose of DAT and enhancement of induction of UDS.Howcvcr, thc mcchanism of the enhancement is not clear.
