[Effects of Eleutherococcus on the biorhythm of indices of peripheral blood in dogs].

The circadian rhythms of the erythrocytes, hemoglobin and leucocytes concentration in the peripheral blood in dogs in winter and the effect of the eleutherococcus multi-injected at different periods of the day, were studied. The changes in the parameters of the studied biorhythms indices were observed only in the after dinner-injected animals, they being marked by the evident increase of the mesor and amplitude, acrophase shift by 1-2 hours by the beginning of the twenty-four hours.
