[Microcirculatory bed of the rat small intestine after nerve reflex isolation].
Intravital biomicroscopy of small intestinal wall vessels was used in experiments on rats undergoing total neuroreflex isolation of the small intestine to study the time course of changes in the diameter of intramural arterioles and venules of the first, second, third and fourth grades. It was demonstrated that neuroreflex isolation of the small intestine is accompanied by long-term deranged coordination of the vascular bed. These shifts appeared to be the earliest and the most significant in the major part of resistive vessels, determining the hydrostatic pressure in the capillaries and shifts in histohematic barriers, as well as in specific functions of the small intestine.
