title: [Mechanism of dilatation of the thoracic duct upon stimulation of somatic nerves].
abstract: In acute experiments on 31 dogs, dilatation of the thoracic lymphatic duct on moderate (5--8 V) stimulation of afferents of the sciatic nerve and i. v. administration of noradrenaline (3--5 mcg/kg) was shown to be due to specific effects of excitation of the duct alpha-adrenoreceptors mainly. The alpha-adrenoreceptors seem to be represented in the thoracic duct in a much greater amount that the beta-adrenoreceptors. Stimulation of both types of the duct's adrenoreceptors leads to an increase in its capacity.
