[Peculiarities of the psychological status of first-year students in terms of university education].

Peculiarities There was performed the study of the mental status of first-year students enrolled in the Tuvan state University. There were detected levels of reactive and personal anxiety, adaptive capacity, the level of social and psychological adaptation and aggression. Adaptation potential in students is within limits of the satisfactory one, there was no detected person with poor adaptive capacity and failure of adaptation, that indicates to the genetically fixed ability of the students’ body to adapt to living conditions.

[SOCIOHYGIENIC FACTORS FOR THE LIFESTYLE IN STUDENTS].

In the paper there are presented the studies of the social status and lifestyle in students of Tuvan and Russian nationality according to self-assessment by students of the material and domestic living conditions, health status, physical development, nutrition, socio-demographic characteristics. Students of the Tuvan University were shown to differ according to a low level of material provision, predominance ofrural students over urban ones, low educational qualifications of parents of students, due to the general socio-economic characteristics of the republic with a low level of urbanization, economic development, features of indigenous way of life. 43.

[The cardiovascular system during adaptation of students residing in a South-Siberian region].

The trend in adaptation processes was studied by the parameters of the cardiovascular system in Tuvian and Russian students during their study at a higher educational establishment. Not only the age- and sex-related features, but also ethnical features of students living under extreme climatic and geographic conditions were shown to affect education adaptation processes. Junior students of natural ethnicity had lower indices of cardiovascular system function than those of Russian ethnicity and a more adequate adaptive response to study.

[Morphofunctional parameters in the students of Tyva State University].

The paper provides a comparative analysis of some morphofunctional parameters and their trends during education of the students at the Tyva State University. The antropometric studies of the total body sizes and their relative parameters have revealed that the Tuva students show a lower absolute stature, force parameters of dynamometry and the respiratory system. The morphofunctional parameters have a wide range of variability that is determined by not only age-gender-related features, but also regional features.

Morphological, functional, and psychological development of children living permanently in the Tyva Republic.

For estimation of national-ethnic features of the development of young school-children, 1,928 children 8-11 years old of the Russian and Tuvinian ethnicity permanently living in urban and rural areas of the Tyva Republic were studied. The level of physical development, parameters of cardio-respiratory system, psycho-physiological status, functional asymmetry of brain, memory and attention were estimated. It was established that despite accelerated development of all children, Tyvinian schoolboys have lower parameters of physical and mental development, but a higher level of functional condition of cardiovascular and respiratory systems in comparison with Russian children.

[Development in ontogeny of the effect of ACTH fragment 4-7 on rat learning].

Studies have been made of the effect of ACTH fragment 4-7 on learning in rats in early postnatal ontogenesis, as well as of the possibility of preservation of early learning during administration of this peptide to adult animals. It was shown that conditioned reaction of active avoidance practically cannot be formed in normal 13-15-day animals; however, administration of ACTH 4-7 increases the number of animals exhibiting adequate reactions. Weak effect of ACTH 4-7 in 12-15-day animals, in older ones (20-24 days) is changed by a significant stimulating effect.
