[Mutagenic effect of the cytostatic drug thaliblastine on rat bone marrow cells when administered alone and in combination with radiation].
The cytogenetic analysis was performed in the bone marrow cells of Wistar rats treated with a therapeutic dose of thaliblastine (250 mg/kg) and exposed to gamma-rays (2 Gy). Thaliblastine alone induced chromosome aberrations and polyploid cells. The latter were the result of the stathmokinetic effect of the drug. In contrast to gamma-radiation of 2 Gy thaliblastine elicited a minor mutagenic effect. The cytogenetic effect of the combined treatment is greater than the sum of the two agents delivered separately, the maximum effect of radiation and thaliblastine being exhibited on the 8th and the 12th hour, respectively. The difference between the sum of aberrations after separate treatments and the yield of aberrations after the combined treatment is due to chromatid fragments.
