title: [Separate and combined mutagenic effect of radiation and asbestos on the micronucleus test in experiments].
abstract: We investigated the isolated and combined mutagenic effect (ME) of radiation (gamma-irradiation, 0.5 or 2 Gy) and asbestos (i.p. 10 mg/mice) in mice CBA. We studied also the antioxidant activity and malonic dialdehyde concentration in blood serum as possible mechanism of ME and its possible modification. For the ME the micro-nuclei incidence in polychromatic bone marrow erythrocytes was scored. The reciprocal modification (potentiation) of both radiation and asbestos ME was established for combination "radiation, 2 Gy + asbestos", the additivity--for combination "radiation, 0.5 Gy + asbestos".
