title: [Intraorganic blood vessels of the gastrointestinal tract under hypergravitation and blockade of the body M-cholinoreactive systems].
abstract: The data on changes occurring in blood vessels of the gastro-intestinal tract at acceleration with a preliminary scopolamin-induced switching off of the M-cholinoreactive systems in the organism are presented. Structural peculiarities of capillaries depending on their functional state and topography are revealed. It has been stated that gravitational overloadings produce the most reactive changes in endothelium of blood capillaries. Preliminarily administered scopolamin increases resistivity of the blood bed to the effect of acceleration.
