Dysfunction of the visceral tract has been considered for a long time to be the cause of diabetes mellitus. Bomskov in 1910 reported severe diabetic symptoms in dogs after cannulation of the ductus lymphaticus. This observation, however, could not be confirmed in later experiments (Vogel HG (1963), Unpublished data). The technique was similar to that described by Gryaznova (1962, 1963) for ligation of the thoracic duct in dogs.
