[Effect of semax on heart rate variability in various daytime periods].
Peptide drug semax with nootropic properties did not change the heart rate variability in rats in the morning, but produced a significant optimizing action and attenuated the stress-induced sympathetic influences on the heart in the evening. It is suggested that semax has a chronotropic activity, which may participate in realization of the specific drug action.
