[Ecological-anthropological aspects of individual morphotype variability of children in Tyumen north].

The complex study of the physical development of boys and girls aged 11-18 years of native and newly come population of Khanty-Mansiysk-Ugra Autonomous Region was performed. It was found that the native population had higher mass of fat component in all the age groups as compared to that of the newly come population. The data obtained reflect the regional peculiarities of the growth processes of the children of native and newly come population.

[The topographic anatomical validation of variants in the surgical treatment of acute mediastinitis in children from the age aspect].

The article is based on 28 experimental studies and 74 clinical observations. The authors have distinguished fascial-cellular spaces of the mediastinum, noted their developmental changes and topographo-anatomical relationships, determined possible ways of spreading the pyo-inflammatory process in the mediastinal fat in children of different age groups. Substantiation of methods of drainage in acute suppurative mediastinitis is given in the age aspect, as well as the method of local detoxication.

[Lactase deficiency among representatives of various nationalities of Siberia].

Some features of lactase tolerance were investigated in representatives of varying groups of indigenous population in Siberia-Mansi, Khanty, Nenets, Buryats. The indirect method was used to evaluate lactase activity. A total of 92 subjects were investigated.

[Topographic and quantitative characteristics of adipose tissue in various aborigines of Siberia (women)].

The main task of the investigation is to prove suitability of the scheme suggested for estimation of the dynamics of fat content in the organism, in order to analyse age changeability of topography and amount of the subcutaneous fat in 254 women of various race-geographic groups in Siberia and populations, belonging to different adaptive groups. Representatives of the central-east-european (Russians), north europeoid (Komi), uralian (Manci) and central-asian (Buryats) race groups have been investigated. Age groups of 18-23 and 24-55 years of age have been compared.
