[Chronic forms of herpetic lesions of the central nervous system in adults (clinico-laboratory and morphological studies)].

Based on analysis of 17 cases with chronic herpetic encephalitis and encephalomyelitis, the authors demonstrate the diversity of the clinical manifestations of the illnesses. A problem of the progredient forms of those neurologic infections is discussed.

[Experimental generalized herpes simplex in guinea pigs with retrobulbar infection].

Modelling of generalized herpetic infection of Guinea pigs is described. It took the course in the form of acute or subacute recurring process with either involvement of separate internal organs, or disseminated involvement of all visceral organs, or principal involvement of subcortical structures of the brain, or involvement of the brain and spinal marrow and marked vegetative failures. Signs of vasculitis; development of disseminated intravascular coagulation (DIC) syndrome and CNS demyelinization are detected in animals during the terminal period.

[Astrocytic glia in the pathogenesis of Creutzfeldt-Jakob disease].

The role of astrocytes in pathogenesis of Creutzfeld-Jakob disease (CJD), one of the slow virus infections of human central nervous system caused by an unconventional virus (prion) has been studied. Histological and ultrastructural examinations of the brain of both dead people and experimentally infected guinea pigs, combined with the data on morphofunctional state of infected monolayer glial culture analysis have shown astrocytes, as well as neurons, to be target-cells for the causative agent of the disease. The astrocyte changes observed were evaluated as proliferative-degenerative ones with the activation prevailing over the cell destruction.

[Clinical polymorphism of herpetic lesions of the central nervous system].

Four groups of herpetic affection of the central nervous system have been described: meningitis, meningoencephalitis, encephalitis and encephalomyelitis. Each condition has a variety of neurological manifestations. Clinico-pathogenic aspects of the problem are discussed.

[Morphological changes in experimental amyotrophic leukospongiosis].

A new nosological entity of slow infections provoked by noncanonical viruses was experimentally studied. It was shown that natural human infection and infection induced in guinea pigs had common clinical and morphological parameters and were characterized by severe changes in the central nervous system. Histologically, the death of the motoneurones of the spinal cord, the spongious state of the white matter of the brain and spinal cord, relative preservation of myelin, hypertrophy and proliferation of macroglia were histologically observed.
