[Microcirculatory bed of the hamster buccal sac under conditions of exposure to exogenous nitric oxide].
Arteriolar and venular reactions and capillary blood flow in response to exogenous nitric oxide were studied on the hamster buccal sac capillaries. Heterogeneous reactions of capillaries were observed after exposure to NO; vasoconstriction and vasodilatation were observed equally often, the reactions of arterioles and venules being specific. The microcirculation index changed negligibly, the fluxmotion index increased due to increasing effects of active mechanisms, and the vascular tone decreased.
