[Effect of vitamins B and C on the intestinal motor activity of rabbits in long-term experiments]

In 3 rabbits in chronic experiments motor activity of the innervated and vascularized pouch of jejunum was frequently registered under the influence of vitamins C, B1, B6 and folic acid before and after the blockade of cholinergic or adrenergic receptors. Vitamins B1, B6 and C decreased the motor activity of intestines but B2 and folic acid increased it. Decreased motor activity of intestines under the effect of vitamin C is probably connected with the stimulation of adrenergic receptors. Adrenergic and cholinergic receptors did not participate in the motor activity of intestines occurring under the influence of group B vitamin. In chronic experiments the intestines excitability to group B vitamin and to that of vitamin C does not differ much.
