[Influence of chronic emotional stress on the behaviour in "open field" test of rats with different level of motor activity].

Experiments were carried out on 41 Wistar mail rats with body weight of 180 - 200 g. It was shown that in 'open field' the rats differed in the level of motional activity. Independently from level of locomotion investigated groups of rats were dissimilar at the criterions for "emotionality" and latent period of go out from the centr of "field".

[Cortical-subcortical mechanisms of emotional behavior and autonomic functions of aging rats].

Experiments were carried out on 24 month (mail, femail) old Wistar rats. It was shown that applications of 25% KC1 for 30 min on the frontal sections of the both cerebral hemispheres accompanied by a decrease in electrical activity of the cortical-subcortical structures, inhibition of the vegetative functions (heart rate) and emotional reactions of the different direction (positive, negative). The degree of manifestation and the character of the changes of the investigated parameters depended on the time of the reversible inhibition of the neocortex and on the age of animals.

[Cortical and subcortical mechanisms of emotional behaviour and vegetative functions in young white rats].

Experiments were carried out on 3 month-old Wistar rats. It was shown that applications of 25% KCL solution on the frontal sections of the both cerebral hemispheres caused a decrease in the amplitude of the potentials and a reformation of the rhythms in the neocortex and subcortical structures. The degree of manifestation, the character and the direction of the changes in the emotional behaviour and vegetative functions (the heart rate) in the young animals with spreading depression in the cortex depended on the time of the reversible inhibition of the neocortex, the initial level of the emotional activity in rats, the type of their emotional behavior, and the functional (compensating) resources of the cerebral systems of the emotional reacting at the level of the cortex-subcortical and intersubcortical interactions.

[The neurophysiological effects of the beta-blocker obzidan in the modelling of emotional stress].

Neurophysiological effects of beta-blocker obsidan have been studied in experiments with 3 month old male Wistar rats under conditions of modelling of emotional disturbances. It is shown that the 7-8 day stress induced profound changes in electrographic, emotional and vegetation reactions of rats. Disturbances induced by the stress are observed for a long-term poststress period.

[A new universal program of postgraduate physician instruction in dermatology and venereology].

The Chair for Dermatology and Venereology at the Central Institute for Advanced Medical Training has developed a new universal programme for advanced training of physicians in this field; this programme is the sole document regulating continuous education of dermatologists and venereologists. It was approved by the Head Administration of Educating Institutions of the USSR Ministry of Health. The programme structure is based on a block system.
