[Tissue basophils in vascular plexuses of the lateral ventricles of the brain in humans and various mammals]. / Tkanevnye bazofily sosudistykh spletenii bokovykh zheludochkov golovnogo mozga u cheloveka i nekotorykh mlekopitaiushchikh.

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.

[Device for smoothing out sections in paraffin embedding]. / Ustroistvo dlia raspravleniia srezov pri parafinovoi zalivke.

An uncomplicated device with automatically maintained optimal temperature of the water is suggested for smoothing out paraffin sections. The device is mounted on the basis of an electric sterilizer switched into the current via a thermoregulator. In the working regimen of the device the required temperature of the water is reached within 15-20 min after switching on.
