[Dynamics of the non-specific reactivity of the organism in time].
Experiments with 10 mongrel rats and dogs showed that individual reactivity of animals to hypobaric hypoxia was same during repeated exposure in two weeks. Investigations of 20 dogs demonstrated relatively permanent types of group reactivity, i.e. hyper-, normal, and hyporeactivity to adrenaline injections every 2 months over a year period. Each type of group reactivity was marked by phase variation in the count of peripheral blood leukocytes with the relation of group mean values unchanged. Analysis of mean values of adaptive levels in 340 subjects with varying individual reactivity over 10 years also pointed to undulation of these values in each group. At the same time, the difference in mean values of this parameter among the groups was kept constant. Hence, the group specific reactivity has a long-range character as determined by testing.
