[Local features of temporal organization of tissue mast cells in the dura mater of mature rat brain].

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.
