title: [Development of the pial microcirculatory system during ontogeny].
abstract: Biomicroscopic studies performed in anesthetized white rats revealed the increase in the cortex mass and the formation of microcirculatory bed as the main factors in microcirculation development. Three periods were distinguished in the process of the pial microcirculatory system formation: an excessive blood flow in the primary capillary net (1-7 days); an unstable (translocating) blood flow and formation of definite structure of the microcirculatory bed (7-30 days); a stable blood flow and stabilizing of the microcirculatory bed construction (75-90 days). A possibility of distinguishing the structural-functional units within the pial microcirculatory system and their role in formation of the microcirculation in ontogenesis, are discussed.
