[Local features of temporal organization of tissue mast cells in the dura mater of mature rat brain]. / Lokal'nye osobennosti vremennoi organizatsii tkanevykh bazofilov tverdoi obolochki golovnogo mozga polovozrelykh krys.

Rhythms of functional activity of mast cells were studied in frontal, parietal and occipital areas of dura mater of mature rats. Chronological organization of mast cells dura mater was established. Circadian component dominated in all rhythms studied. Local peculiarities of mast cells rhythms were established; frontal area cells displayed most significant oscillations per day. They also showed maximum values of average day number and acrophase. Maximum functional activity was demonstrated in mast cells of frontal and parietal region one hour later than in parietal area of dura mater.

[Biological rhythms of tissue basophils of the dura mater of rats under the effects of noise-vibration]. / Biologicheskie ritmy tkanevykh bazofilov tverdoi mozgovoi obolochki krys pri shumovibratsionnom vozdeistvii.

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.

By means of the histochemical and morphometric methods the reaction of the tissue basophils of the brain dura mater has been studied to the one-time and varying-duration (0.5 sec.-3 hr.) irradiation by a helium-neon laser of the wave length 632.8 nm, power density 0.76 mvt/sm2. It has been found, that the laser irradiation had a biostimulating effect upon the tissue basophils; the first peak of activity is in the case of a 3-second continuous irradiation; the second--from 15 min. to 1 hr. In symmetrical parts of the right (irradiated) and left (nonirradiated) regions of the dura very similar changes of the functional activity of the tissue basophils activity were seen.
