  • Title: [Comparison of the frequencies of sister chromatid exchanges induced by thiophosphamide in vivo and in vitro].
    Author: Stukalov SV, Chebotarev AN.
    Journal: Biull Eksp Biol Med; 1983 Apr; 95(4):74-5. PubMed ID: 6403075.
    Abstract:
    The effects of thiophosphamide on rabbit lymphocytes were studied and compared in vivo and in vitro. In the course of in vitro action the dose was calculated by multiplying the thiophosphamide concentration by the time of in vitro treatment. In vivo the dose was calculated as integral of concentration variation function of thiophosphamide from the time of injection till the time of blood collection. It was demonstrated that as the dose was raised, the rate of sister chromatid exchanges increased linearly in vivo and in vitro. The coefficients of linear regressions were found to coincide. The data point to equal efficacy of thiophosphamide in vivo and in vitro.
