[Age-related changes of morphometric parameters of the human duodenum]. / Vozrastnye izmeneniia morfometricheskikh parametrov dvenadtsatiperstnoi kishki u cheloveka.

[Morphometric characteristics of coronary atherosclerosis in different ethnic groups of Andizhan population]. / Morfometricheskaia kharakteristika ateroskleroza koronarnykh arterii v razlichnykh étnicheskikh gruppakh naseleniia Andizhana.

A gross morphometric study of coronary atherosclerosis was performed in 554 native males aged 20-59 years and 142 migrant males of the same age from Andizhan according to the WHO Expert Programme (Bull, WHO, 1976, vol. 53, p. 485). The migrants over 40 years displayed a greater extent of atherosclerosis (except lipid streaks) than did the natives; but there were small differences between the comparable groups of young persons under 40 years. A histometric study of the coronary arteries was made in 81 apparently healthy males indicated that fine-dropped (mainly intracellular) lipid deposits were more common in the natives, mixed (fine- and coarse-dropped) and coarse-dropped lipid deposits occurring with cell breakdown were seen in the migrants. The thickness of atherosclerotic lesions in the coronary arteries was greater in the migrants. Varying degrees of coronary intimal hyperplasia were found in individuals from the comparable ethnic groups. The hyperplasia was more profound in the migrants. There was a direct relationship between its degree and the development of atherosclerotic lesions.

[Age-related dynamics of aortic atherosclerosis of various ethnic groups of the male population of Andizhan]. / Osobennosti vozrastnoi dinamiki ateroskleroza aorty u razlichnykh étnicheskikh grupp muzhskogo naseleniia Andizhana.

Quantitative study of the aortic atherosclerosis was performed in 587 males of the indigenous (IP) and in 149 males of non-indigenous population (NIP) at the age of 20 to 59 years in the city of Andizhan according to the WHO program. The course of atherosclerosis was more severe in NIP persons although at the age of up to 40 years the differences in the mean surface of atherosclerotic changes were lacking. The surface of lipid spots was similar in both groups or was somewhat lower in NIP, but these spots in NIP persons were thicker and contained more foam cells and more areas of diffuse lipid deposition. The rate of the surface increase of prominent lesions drastically increased in the 5th decade of life in both groups. The frequency of rhythmical structures in the aorta was the same in both groups; their incidence was higher in cases of pronounced atherosclerosis.
