Biological Dose Assessment by Chemical Induction of Premature Chromosome Condensation
Dose assessment of radiation victims is a key element in medical management of radiation accidents. At high radiation doses (> 6 Gy), dicentric assay lose its efficiency and premature chromosome condensation (PCC) assay was proposed to overcome the restrictions of dicentric assay. It was shown that PCC ring is more suitable and simpler than dicentric for biodosimetry in high radiation doses. In...
متن کاملInduction of chromosome aberrations in human lymphocytes by technetium-99m. In vitro and in vivo studies
INTRODUCTION Research on the effects of low-dose exposure to ionizing radiation in human has been widely studied. In diagnostic Nuclear Medecine, calculated doses delivered to whole-body and organs were very low (1) and scintigraphies are considered as safe. Consequently only a few studies concerning the potential biological and genetic effects of radiopharmaceutical administration have been ca...
متن کاملEffect of hypothermia and hyperthermia on the induction of chromosome aberrations by adriamycin in human leukocytes.
When human leukocytes are treated with adriamycin (ADR) for brief durations of 1 to 2 hr at concentrations ranging between 0.04 and 0.25 microgram/ml, a dramatic reduction is observed in the frequency of chromosome aberrations in cells treated at 4 degrees in comparison to those treated at 37 degrees. Conversely, a severalfold increase in the frequency of aberrations is found if temperature at ...
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 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...
