Radiation-induced chromosome damage in human lymphocytes.
Analysis for chromosome aberrations in human peripheral blood lymphocytes has been developed as an indicator of dose from ionising radiation. This paper outlines the mechanism of production of aberrations, the technique for their analysis and the dose-effect relationships for various types of radiation. During the past ten years the National Radiological Protection Board has developed a service...
متن کاملUltrastructural Studies of Radiation-induced Chromosome Damage
The fine structure of radiation-induced chromosomal aberrations in Potorous tridactylis (rat kangaroo) cells was examined in situ by electron microscopy. The observations on the structure of terminal deletions (acentric fragments), anaphase bridges and "gaps," sidearm bridges, and specialized regions, such as the nucleolus organizer, are discussed in detail. Conclusions based on these observati...
متن کاملNature and consequences of induced chromosome damage in mammals.
There are marked qualitative and quantitative differences in the patterns of chromosomal damage observed after irradiation of spermatogonia, spermatozoa and oocytes of mice. These differences often result from reduced or zero transmission of particular classes of abberration arising in pre-meiotic germ cells. Probably this is the reason why the level of X-chromosomal and autosomal monosomy is n...
متن کاملChlorambucil induced chromosome damage in juvenile chronic arthritis.
Sister chromatid exchanges, a sensitive measure of chromosome damage, were counted in peripheral blood lymphocytes from 23 patients with juvenile chronic arthritis receiving long term, low dose chlorambucil treatment. Thirty five patients with juvenile chronic arthritis who had not been treated with cytotoxic drugs served as controls. All of the treated patients have cells with abnormal sister ...
متن کاملThird-chromosome mutagen-sensitive mutants of Drosophila melanogaster.
A total of 34 third chromosomes of Drosophila melanogaster that render homozygous larvae hypersensitive to killing by chemical mutagens have been isolated. Genetic analyses have placed responsible mutations in more than eleven complementation groups. Mutants in three complementation groups are strongly sensitive to methyl methanesulfonate, those in one are sensitive to nitrogen mustard, and mut...
