Inhibition of spontaneous lymph vessel contraction evoked by transmural stimulation

In isolated sections of mesenteric lymphatic vessels, the constrictory responses to transmural electrical stimulation were studied. Inhibition of the spontaneous rhythm occurring primarily at low frequencies was revealed as well as the inhibition following the excitatory effect of high--frequency st...

Summary:In isolated sections of mesenteric lymphatic vessels, the constrictory responses to transmural electrical stimulation were studied. Inhibition of the spontaneous rhythm occurring primarily at low frequencies was revealed as well as the inhibition following the excitatory effect of high--frequency stimulation. Analysis of the transmural inhibition showed the latter to occur as the result of activation of adrenergic nervous plexus and to be fulfilled by the beta--adrenoreceptors.
