[The adrenergic innervation of the thoracic lymphatic duct in dogs in postnatal ontogeny].

Using histochemical fluorescence technique, studies have been made on the adrenergic innervation of the wall of the thoracal lymphatic duct in postnatal development of puppies. Adrenergic fibers were found in the adventitial layer of the duct. During postnatal development of the animals, adrenergic innervation of this duct becomes more perfect, reaching the level of adult animals to the age of 2-3 months.
