Analysis of the chromosome aberrations induced by x-rays in somatic cells of Drosophila melanogaster.
A technique has been perfected for enabling good microscope preparations to be obtained from the larval ganglia of Drosophila melanogaster. This system was then tested with X-rays and an extensive series of data was obtained on the chromosome aberrations induced in the various stages of the cell cycle.-The analysis of the results obtained offers the following points of interest: (1) There exist...
متن کاملChromosome aberrations in astronauts
A review of currently available data on in vivo induced chromosome damage in the blood lymphocytes of astronauts proves that, after protracted exposure of a few months or more to space radiation, cytogenetic biodosimetry analyses of blood collected within a week or two of return from space provides a reliable estimate of equivalent radiation dose and risk. Recent studies indicate that biodosime...
متن کاملChromosome aberrations as a measure of mutagenesis: comparisons in vitro and in vivo and in somatic and germ cells.
Structural alterations to chromosomes constitute a significant portion of the genetic damage produced by most mutagenic agents. The pioneering experiments of Muller (1), in the case of ionizing radiations, and of Auerbach (2), in the case of nitrogen mustards, showed that chromosome aberrations are, quantitatively, a significant class of mutational events for both physical and chemical mutagens...
متن کاملGENETIC EFFECTS IN SOMATIC AND GERM CELLS IN RABBITS FOLLOWING EXTERNAL GAMMA RADIATION II. Chromosome aberrations in peripheral blood lymphocytes
The aim of the present study was to evaluate the effect of gamma irradiation on the hereditary structures of peripheral blood lymphocytes and to quantify this in a dose-effect study. We used adult male rabbits subjected to total gamma irradiation at a dose range of 0.5 − 3.0 Gy. Twenty-four (24) hours later, we began the process of culturing and determination of chromosome aberration frequency ...
متن کاملChromosome Aberrations in B Lymphocytes
Although chromosome aberrations in T lymphocytes and bone marrow cells have been reported in atomic bomb survivors, the presence of chromosome abnormalities has not been demonstrated in B lymphocytes because of the technical difficulties involved in B-lymphocyte separation. A method for detecting chromosome aberrations in B lymphocytes was established by “stimulation” of B lymphocytes with Epst...
