title: [Population characteristics of mucous tissue basocytes in the Mongolian gerbil's jejunum following the 12-day orbital flight onboard space platform "Foton-M3"].
abstract: Optical (light) microscopy and histochemical techniques were used for the first-ever studies of the population characteristics of tissue basocytes in the jejunum mucous membrane in three groups of gerbils Meriones unguiculatus: flown over 12 days aboard space platform Foton-M3, subjected to spaceflight factors simulation (SFS) in dedicated system Kontur-L (2) and maintained in standard vivarium conditions (control). Space flight was shown to induce quantitative and qualitative changes in the population of jejunum mucus labrocytes. Reduction of the basocytes population, alterations in age composition and ratio of the morphofunctional cell types in microgravity were indicative of cytoplasmic aggregation intensity, paths of biosynthesis products release into the intersticium, and their tinctorial properties. Also, heparin maturation and liberalization into the extracellular space in support of the jejunum mucus adaptive functions progressed with greater intensity. SFS did not affect size of the basocytes population significantly although it did cause qualitative rearrangements in the population structure.
