Induction of micronuclei by diesel emission particle extract (DEPE) in mouse bone marrow cells was suppressed by pre-treatment with ascorbic acid, ${\alpha}-tocopherol$ or glutathione (GSH). These compounds were given orally to mice at the dose of 1, 10 or 100 mg/kg/day for 5 consecutive days. The dose of DEPE (200 mg/kg) was administered intraperitoneally once to mice with the 5th administration of test compounds. Ascorbic acid, ${\alpha}-tocopherol$ and GSH all showed the dose-dependent suppression on DEPE-induced micronuclei.
