  • Title: Comparative studies on spontaneous and mitomycin-C-induced sister-chromatid exchanges in smokers and non-smokers.
    Author: Cui M, Xu J, Zhou X.
    Journal: Mutat Res; 1982 Sep; 105(3):195-200. PubMed ID: 6815523.
    Abstract:
    Both spontaneous and mitomycin-C-induced sister-chromatid exchanges were analyzed in 6 smokers and 6 non-smokers. The average number of spontaneous SCE in smokers' cells was 8.33 +/- 1.08. The frequency in the non-smoking controls was 4.41 +/- 0.72. This difference is highly significant (P less than 0.001). Smokers also had more SCE at all levels of mitomycin C testes. Analysis of variance showed these differences to be highly significant (P less than 0.001).
