[Lymph pressure dynamics in somatic and mesenteric lymphatic channels at rest and at the height of digestion].

An original rapidly acting tensoresistive pressure transducer was used to study the lymph pressure in the popliteal and mesenteric lymph nodes and vessels of the dog without liquid injection into the lymph channels. The characteristics of the lymph flow in the drained organs was compared at a relative rest, while for the mesenteric lymph channels at the height of digestion. During digestion the lymph pressure in the vessels and nodes is 2-3 times higher than on an empty stomach, and the waves of tonic activity occur more frequently and energetically. The lymph pressure in the lymph nodes is lower than in the efferent vessels of these nodes.
