“…The smooth muscle fibers loosely associated with the central lacteal (PAPP et al, 1962) also may facilitate lymph propulsion by contracting the lacteal on its long axis. Spontaneous contractions of the central lacteal have been suggested (PAPP et al, 1962).…”

“…Spontaneous contractions of the central lacteal have been suggested (PAPP et al, 1962). On the other hand, the intestinal villus during its elongation may expand the contained central lacteals with the aid of the lymphatic anchoring filaments (LEAK and BURKE, 1968;BocK,1978), and thus create a relative pressure which results in its filling (ALLEN, 1967).…”

“…Hitherto, ultrastructural observations on normal lymphatic vessels in which there were good grounds to infer that they were actively absorbing materials from the extracellular space have been confined largely to the lacteals of the intestinal villi [Casley-Smith, 1962;Palay and Karlin, 1959a and b;Papp et al, 1962] and to the lymphatics of the diaphragm [Casley-Smith, 1964;Casley-Smith and Florey, 1962;French et al, 1960] Smith and Florey, 1961;Fraley and Weiss, 1961], have opened in the manner of 'flap valves' in response to the tissue pressure being higher than the lymphatic, to permit the passage of materials into the lymphatic lumen [Casley- Smith, 1962Smith, , 1964French et al, 1960;Leak and Burke, 1966;Papp et al, 1962]. It is implicit in this assumption that any rise in intralymphatic pressure that would cause the passage of fluid out of the lumen back into the tissues would close the flap valves more or less immediately.…”

The lymphatics of the bat's wing could be separated in vivo into two morphologically and functionally distinct types. Vessels selected for subsequent electron microscopy were labelled in vivo with Berlin blue which could be readily identified in the electron microscope. The terminal bulbs which are responsible for absorption of fluid and particles from the tissues have walls composed of a single layer of endothelium lined on its abluminal surface by a generally tenuous condensation of fibrillar material. Absorption is considered to occur through large gaps present in the endothelial lining. Although the endothelial junctions have no specialized attachment zones, no evidence was obtained for any flap-valve action in these regions. No gaps were found in the endothelial layers of the collecting and transport channels. The transport channels which are contractile and are responsible for the propulsion of lymph in vivo contain smooth muscle cells in their walls. These cells are not innervated. The cusps of the lymphatic valves are simply two layers of endothelium separated by a narrow zone containing fine fibrillar material. The endothelial cells are phagocytic to the marker particles.The lymphatic system of vertebrates is responsible for the reabsorption of part of the water and electrolytes and most of the proteins that are continuously leaving the minute blood vessels to bathe the cells of the body tissues [Drinker, 1946;Courtice and Morris, 1955]. The importance of this function can be appreciated in the rapid deterioration in the condition of animals and human beings with chronic thoracic duct fistulae which are draining large quantities of lymph to the exterior Drinker, 1946]. Lymphatics of the tissues, in order to fulfil their physiological role, must have two important properties. One is to be able to collect fluid from the tissues, and the other is to move the fluid away from the site of collection and back, generally via the thoracic duct, into the circulating blood stream. Valuable information has been obtained from in vivo observations of lymphatic function in the amphibian tail [Clark, 1912;Clark and Clark, 1920], in the rabbit ear chamber [Clark and Clark, 1932, 1933, 1937, in rat mesentery [Webb, 1933], in the mouse ear [McMaster, 1947;Pullinger and Florey, 1935], in a variety of acute dissected preparations in mammals [Florey, 1927;Pullinger and Florey, 1935;Smith, 1949] and in the membrane of the bat's wing [Webb and Nicoll, 1944]. There has not been any direct extension of in vivo observations such as these so as to correlate observed physiological function with ultrastructural morphology on the identical vessel. The present experiments were performed to relate the in vivo properties of selected lymphatic vessels in the wing membrane of the bat with their ultrastructure observed after fixation and embedding for electron microscopy.

“…Unsere Interpretation (s. 2.d), daß es sich hier ebenfalls um Zonen einer T ransm itterfreisetzung handelt [s. a. Papp et al, 1962], wird durch ähnliche Befunde (aus der Magenschleimhaut) und Ansichten von R atzeniiofer et al [1969[ ] und Dermitzel [1971, einem Schüler Brettschneiders gestützt. Der m orpholo gische Nachweis von Schleim hautrezeptoren steht also immer noch aus.…”
