[The role of typological differences in animal behavior during the process of adaptation to extreme situations].

In relation to Cosmos experiments behavioural responses of rhesus monkeys were investigated and compared with their conditioned reflex activities. The animals with a distinct search-oriented behaviour showed a higher rate of recovery of instrumented reflexes, better stability of conditioned-reflex activities to stress-effects and a faster adaptation to them. Extreme effects associated with changes in the experimental environment and rigid fixation inhibited conditioned-reflex activities to a greater extent than strong but short-term exposures followed by tests in a normal environment.

[Clinico-epidemiological characteristics of mentally ill patients identified in the therapy department].

A clinico-epidemiological study was made of the incidence of mental diseases among the adult community visiting the therapeutic department of a city polyclinic. Mental patients registered at the PND (41.9 per 1000 population) underwent examinations.

[Effect of long-term hypokinesia on characteristics of phasic-tonic motor activity in monkeys].

Male rhesus-monkeys, 5-6 years old, were kept in recumbency for a long period of time during which they had to perform phasic-tonic motor tests. The monkeys showed significant changes in the tonic component of the motor act which led to a substantial deterioration of performance parameters on hypokinesia days 20 to 30. The process of recovery began immediately after exposure and on readaptation days 14-15 the tonic component of the motor act returned to normal.

[Histocompatibility antigens and remissions in schizophrenia: relation to clinical parameters].

The character of the distribution of the HLA system antigens was studied in 61 schizophrenic patients. The phenotype of patients with good-quality remissions was characterized by the presence of the antigens HLA-A1, HLA-B8, or their combination.

[Typology of the final stages of juvenile malignant schizophrenia (clinical follow-up study)].

Basing on follow-up studies (for 10 and more years) of the final stages of juvenile malignant schizophrenia (79 patients), a new principle of differentiating the final stages is advanced, suggesting that they should be divided into "psychotic" and "deficient" ones. The authors describe the features of dementia in patients with juvenile malignant schizophrenia, with these features being determined upon relative weakening of massive catatonic delusional-hallucination disorders seen in the patients. Moreover, a special symptom-complex of ecmnestic character with a picture of the "life in the past" is reviewed.
