STATE OF COLLAGEN FIBERS IN STOMACH MUCOSA IN SCHOOLCHILDREN WITH GASTRODUODENAL DISEASES IN SIBERIAL POPULATIONS
We report on the findings of our morphological research for histoarchitectonics of collagen fibers in mucosa in the body of stomach in 163 native and alien (Europoids) schoolchildren of Evenkia (Extreme North) and 181 schoolchildren of Tyva Republic (Southern Siberia) with dyspepsia syndrome. In the North the majority of children, disregard to their ethnic belonging, showed the changes in histoarchitectonics of collagen fibers in stomach mucosa, which characterize different stages of sclerogenic process: formation of bundles and sclerosis hotbeds. At the same time in native children the said changes were marked more often associated with shorter duration of dyspeptic complaints. Larger share of the changes in natives relates to the absence of organic gastroduodenal pathology and less active gastritis in comparison with aliens of Evenkia. In Tyva we found the same changes in 2,8 % cases only.
