[Biological rhythms of tissue basophils of the dura mater of rats under the effects of noise-vibration].

The biorhythmologic changes of tissue basophils (mast cells) have been investigated of mater rats in frontal, temporal and occipital regions of dura mater during the noise-vibration stress. Local differences were found in biorythmological characteristics of tissue basophils before and after vibration. The investigated regions of dura mater after noise-vibration stress the magnitude of harmonics, mesor and the amplitude of fluctuations increased greatly. But, judging by their values, in the temporal region the rhythm stability was lower than that in the frontal and occipital. The tissue basophils of various regions of dura mater react in a different way to the noise-vibration stress.
