Ultrastructural changes were followed in the isolated mechanoreceptor neurons of the crayfish during post-excitational short-term trace processes (i.e. acceleration of the adaptional state), after repeated adaquate excitations. Fibrillar rearrangements of the mitochondrial cristae in the axonal mitochondria took place at the moderate excitation, no visible(More)
We have demonstrated the protective effect of natural antioxidant coenzyme Q-9 on the T-cell proliferative capacity and chromosomal DNA state under low dose chronic irradiation. The DNA-staining fluorescent dye Hoechst-33258 and acridine orange were to observed the nuclear morphology changes in T-lymphocytes. Ubiquinone diet partially restored the(More)
Repetitive remodeling and renewal of the cytoplasmic structures realizing synthesis of proteins accompanies the cycling of ground squirrels between torpor and arousal states during hibernation season. Earlier we have shown partial loss of ribosomes and nucleolus inactivation in CA3 hippocampal pyramidal neurons in each bout of torpor with rapid and full(More)
A similarity in the sequence of restoration of the EEG spectrum between ground squirrels arousing from torpor and rats passing out of artificial hypothermia (17-18 degrees C) was shown. First of all, the low-frequency part of the EEG spectrum was restored. As animals warmed up, their breathing became hurried, cold shivering appeared, and the theta- and(More)
Literature and our own data on structural and functional state of neocortex and hippocampus during both entrance in hibernation of ground squirrel (Spermophilus undulates) and Wistar rats in hypothermia were generalized. During hibernation when body temperature is about 2-4 degrees C the suppression of both bioelectrical and protein-synthesizing activity,(More)
By cytofluorometry the distribution of cells was studied according to the amount of DNA in a population of BHK-21 cells placed in the media containing a serum fraction that either does not stimulate cell proliferation, or stimulates it until reaching 60% of the limiting density observed in the control. The analysis of cell distribution shown that after the(More)
