title: [Determination of genome dose of active ribosome genes and several quantitative parameters of extracellular dna in test-subjects of the experiment with 7-day immersion].
abstract: Genome dose of active ribosome genes (ARG), average of nucleolus argyrophil structures in lymphocyte nuclei, levels of extracellular DNA (DNA(e)) concentrations and ratio of antibodies to total DNA (AB(DNA)) and ribosomal DNA (AB(DNA-rib)), and nuclease activity were determined in peripheral blood of 8 volunteered subjects (21-26 y.o.) in the experiment with 7-d DI. Results of the investigation revealed a broad individual variability ensued from heterogeneity of the group of the test-subjects as to ARG values. There was an inverse negative relationship between ARG values and increment of the ribosome genes activity index. Part of the subjected exhibited increased DNA(e) levels on completion of the experiment, whereas the others decreased the parameter demonstrating individual character of body reaction. No correlation was established between DNA(e) content and nuclease activity in blood. Concentrations of AB(DNA) and DNA AB(DNA-rib) before and after immersion were essentially unchanged; however, they were higher as compared with the control group of blood-donors. Diversity of subjects' reactions was accounted to the broad range of ARG values. Therefore, selection of test-subjects for ground-based simulation experiments should be conducted with due consideration of the parameter.
