[Infradian rhythm of functional status of neutrophils and lymphocytes from blood of rats with various constitutional features].

The rhythmical oscillations of the functional condition indicators in neutrophils (the peroxidase, the lipids) and in lymphocytes (the succinic and glycerophosphate dehydrogenases) with the periods: 17 +/- 1.2; 13.6 +/- 1.6; 9.7 +/- 1.0; 7.2 +/- 0.5; 3.5 +/- 0.2 days have been revealed in the rats with the low, middle and high motive activity in the "open field" test. It has been elucidated, that the amplitudes of the revealed rhythms, the phasal correlations as well as the degree of the indicators synchronization between each others differ in the animals with the different constitutional peculiarities.
