[Mechanism of changes in central lymphatic volume flow with increase of pressure in the left atrium].
In anesthetized adult dogs, stimulation of left atrium receptors caused an increase in the central lymph volume flow and a raise in transport capacity of the thoracic duct. Neither vagotomy nor blockade of muscarinic cholinergic fibers affected the reflex shifts in lymph volume flow or thoracic duct lumen. The efferent link of this reflex is represented by adrenergic nerve fibers.
