[Electron microscopic and cytochemical research on the function of the glial cells in a focus of local cortical destruction].

The activity of DNA-RNA-protein synthesizing system of some glial cells was studied using electron cytochemical method for determination of chromatin state and RNA-particles. A dependence of functional state of satellite glial cells (oligodendroglia and astroglia) on the tinctorial neuron state (hyper- and hypochromic scale) was shown. The functional state of interfascicular oligodendroglial cells has been characterized.

[Characteristics of hyperchromic neurons from a focus of local cortical destruction].

Using the Bernhard method of differential staining of ribonucleoproteins the sequence of neuronal destruction by a hyperchromic manner has been demonstrated in the focus of local destruction in the rat brain. This process is marked by a decrease of nuclear synthetic activity, inhibition of the nuclear-cytoplasmic transport, transition of the nucleus components to a metabolically inert state followed by the hydrolysis of the nuclear ribonucleoprotein particles, and destruction of cytoplasmic mitochondria. The processes of neuronal destruction by a hyperchromic manner are culminated in neuronophagia on the part of the oligodendroglia.

[Changes in the dendritic organization of the neurons of the isolated visual cortex of the cat].

The cortex of one hemisphere in cats was isolated according to M.M. Khananashwili method by means of surgical section of its projection fibres which connect it with subcortical structures.
