People come into contact with chemical and physical agents which are present in the environment and in workplaces. We investigated the effects of combined exposures to low doses of X-rays (0.05-0.25 Gy) and acrylamide (AA; 75 mg/kg bw) in the somatic and germ cells of outbred male mice by using a bo

✦ Synopsis
The induction of micronuclei in polychromatic erythrocytes of bone marrow of Pzh:SWISS mice after combined treatment with X-rays and cyclophosphamide (CP) or X-rays and mitomycin C (MMC) were investigated. Combinations of high (1.00 Gy + 100 mg/kg bw CP and 1.00 Gy + 5.25 mg/kg bw MMC) and low (0.25 Gy + 25 mg/kg bw CP and 0.25 Gy + 1.75 mg/kg bw MMC) doses were used. Both chemicals enhanced the mutagenic effects caused by irradiation. After combined treatment with high doses of X-rays + CP and X-rays + MMC at different sample times increases in frequency of micronuclei were observed. Mutagenic effects were found also after treatment with two low doses, when irradiation alone produced no effects. The effects of combined treatments are generally similar to the additive effect of the single treatments.

People are widely exposed during their lifetime to many biological, chemical, and physical agents in the environment and at work. In this paper the effects of combined exposures of nonmutagenic doses of X-rays and anticancer agents (cyclophosphamide, mitomycin C, and vinblastine) have been investiga
