  • 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.

  • The clastogenic effects of the diesel emission particle extract (DEPE), mercuric chloride and lead acetate were examined by the mouse bone marrow micronucleus test. DEPE had a potent clastogenic effect by intraperitoneal injection with dose-response between 100 and 300mg/kg b.w.. Mercuric chloride and lead acetate also gave a clastogenic effects but mercuric chloride only had a dose-response between 1 and 3mg/kg b.w.. When DEPE was administrated with mercuric chloride or lead acetate, the frequency of micronucleated cells was slight but not significant increase in comparision to a single treatment with DEPE alone.
