[Microcirculatory bed of the small intestine in different phases of its motor activity].

Experiments were conducted on guinea pigs, rabbits and rats with a simultaneous recording of the motor activity of the small intestine and the state on its microcirculatory bed, it was shown that the diameter of parietal vessels of the small intestine depended on the contractile activity of the muscles of this intestine. Proceeding from these data the authors explained the mechanism of derangement of the secretory and absorptive function of the small intestine after its neuro-reflex isolation and transplantation.
