[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.

[Device for smoothing out sections in paraffin embedding].

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.
