[A clinico-physiological and psychological-pedagogical analysis of the structure of the defect in cognitive activity in 3 cases of different forms of speech pathology].

Clinical (neurological), neurophysiological (EEG) and psychological examinations were carried out in 3 children with general speech defects. These children represented 3 main groups with speech disturbances: with speech defects which may be logopedically corrected, with speech defect and intact intellectual ability, with considerable disturbances of speech and cognitive functions. The peculiarities of cognitive disturbances were determined in each group.

[A live vaccine against tick-borne encephalitis: the principles of selecting the vaccinal strains].

The comparative, semiquantitative, pathomorphological study of the neurovirulence of clones of Elantsev virus and Langat virus TP-21 for intracerebrally infected monkeys has been carried out. The study has revealed that the viruses may be differentiated by their neurovirulence for primates according to the average statistical data on the degree of pathomorphological changes in the central nervous system, but not to maximum lesions in cerebral structures. The level of neurovirulence of yellow fever virus 17D was formerly considered to be the highest admissible limit of residual neurovirulence of encephalitogenic viruses (flaviviruses).
