Grechkosij N. 3. The postnatal period of thymus chickens ontogenes of kross "Loman-Braun"

3. Thymus of hens. Objective - to study structure, growth and development of hens thymus of "Loman-Braun" cross in postnatal period of ontogenes. Anatomical preparation, macro-, microscopical, cytomorphological, cytochemical, light microscope. For the first time complex investigation of topography, macro- and microstructure of hens thymus of "Loman-Braun" cross and cell composition of its pa-renchyma in postnatal period of ontogenesis was con-ducted. Introduction to scientific research is planning and it is partially made while studying animals morphology and in preparation of appropriate manuals and textbooks. Investi-gation results increase knowledge about organs of immu-nogenesis. Veterinary medicine, immunology, poultry breeding.
