The low-molecular-weight DNA appears in blood plasma of irradiated rats, and its content correlates directly with the irradiation dose. Cloning has shown, that enrichment of low-molecular-weight DNA with G+C content and features of its nucleotide sequences point to its ability to form rather stable nucleosomes. DNA obtained after irradiation of rats with(More)
At the end of the 1970s, with the appearance of reliable methods of investigation, there appeared well-substantiated reports that the blood plasma of animals and man contains certain quantities of DNA [3, 6, 8]. Subsequent tests showed that in some pathological states this DNA level may rise. In particular, this happens during the development of certain(More)
It was shown experimentally that ionizing radiation and low-frequency noise increase the level of extracelular low-molecular DNA in rat's blood plasma. Growth of this parameter has been observed in acute stroke patients at the onset of the disease. Low-molecular DNA assay is proposed for evaluation of the unfavorable effects of physical factors on organism.
Low-frequency noise has been shown to cause certain functional changes in the organism of laboratory animals that manifest in changes of the state of the regulatory systems and metabolic disturbances at cellular and subcellular levels. The obtained data support the hypothesis of the mechanism of injurious effect of this physical factor including two(More)
Intact rat plasma contains high-molecular DNA which moves as a single fraction in 0.5% agarose electrophoresis. As early as 2-5 hours after gamma-irradiation in a dose of 1-100 Gy there appears low-molecular DNA (about 180 nucleotide pairs), the amount of which directly correlates with the irradiation dose 5 hours after the exposure. Blot-hybridization(More)
