[Combined functioning of lymph-blood plasma systems in regulating lipid balance in dogs].

Active participation of lymphatic system in the reconstruction of cholesterol pool during its passage from the intestinal lymph to the thoracic duct lymph was revealed. This phenomenon depends both on the directional dilution of intestinal lipids in the thoracic duct lymph and enzyme mechanisms of the maintenance of lipid balance occurring with the aid of lecithin-cholesterol-acyltransferase and lipoprotein lipase. The rate of transformation of the cholesterol pool correlates with the volume speed of thoracic duct flow. Walls of the intestine, lymphatic and circulatory systems seem to function within the framework of a single mechanism controlling the adequate status of circulatory lipids.
