[Local differences in the tissue basophils of the cerebral dura mater in the rat]

Tissue basophils (TB) were investigated in 5 (occipital, right and left frontal and parietal) areas of the dura mater in 75 albino rats by histological and histochemical methods. Local distinctions in the structure, distribution and functional activity of cells were found. The greatest concentration of TB revealed by staining with methylene blue, cytochrome oxidation reaction and with glyoxylic acid was found in the frontal areas and the lowest concentration in the occipital areas of the mater. The amount of cells with activity of succinic dehydrogenase in the occipital area was, on the contrary, 11-13 times greater than their amount in the frontal and parietal areas of the mater. The local distinctions of TB marked with ATPase are not so considerable and those of alkaline phosphatase were not significant. The frontal areas (right and left) were found to have the greatest concentration of the degranulated forms of TB as well.
