[Individual variations in the frequency of chromosome aberrations following exposure to chemical mutagens. III. Interindividual differences at different stages of the cell cycle]. 1976

T O Tarusina, and K N Iakovenko

The object of this investigation was the sensitivity to chemical mutagens of chromosomes of human lymphocytes obtained from different individuals. The distribution of individuals with respect to their sensitivity to fotrin and cytosine-arabinoside was studied. Tests for two characteristics were used, viz. "the percent of aberrant metaphases" and "the number of chrimosome breaks per 100 cells". It is shown by the statistical analysis, that the distribution does not depend on the stage of the cell cycle. The distribution of the individuals tested with respect to their sensitivity to mutagens was shown to be normal. Certain recommendations concerning the planning of experiments and the exposure of the experimental data are given by the authors.

D002875 Chromosomes In a prokaryotic cell or in the nucleus of a eukaryotic cell, a structure consisting of or containing DNA which carries the genetic information essential to the cell. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Chromosome
D003561 Cytarabine A pyrimidine nucleoside analog that is used mainly in the treatment of leukemia, especially acute non-lymphoblastic leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle. It also has antiviral and immunosuppressant properties.
