[Tissue basophils in vascular plexuses of the lateral ventricles of the brain in humans and various mammals].
By means of histological and histochemical methods cell composition of vascular plexuses in the lateral ventricles of the rats, dogs and man has been investigated. Besides ependymocytes, endotheliocytes, pericytes, myocytes in the microcirculatory bed, described in literature, tissue basophils (TB) have been revealed and what is more--only in dog and man. The most variable forms and localizations of TB are observed in vascular plexuses of the lateral ventricles of the human brain. The following varieties of TB can be defined: small with ortochromic granularity and large ones with abundant metachromic granularity. Sometimes degranulating TB occur. According to their localization they are divided into stromal (+interstitial++), perivascular subepithelial and intraepithelial. The variable TB localization in the vascular plexuses of the brain can probably demonstrate their participation in performing functions of the hematoencephalic barrier.
