Ascites developed promptly in four dogs in which the supradiaphragmatic vena cava was constricted. In another six dogs undergoing the same operation, the thoracic duct was drained by cannula into the esophageal lumen; ascites did not occur. Ascitic fluid forms following constriction of the inferior vena cava by leakage of excess liver lymph into the peritoneal cavity. Capacity of the thoracic duct to transport an increased quantity of lymph is limited by resistance to flow at the veno-lymphatic junction in the neck. This study demonstrates that ascites does not occur when resistance to excess thoracic duct lymph flow is removed by permitting free flow of lymph into the esophagus.

Duct Lymph

Water immersion (WI) increases plasma volume in awake dogs. The contribution of lymph flow to this fluid shift was studied in six splenectomized conscious dogs with a side fistula of the thoracic duct. Lymph flow, hematocrit (Hct), and plasma (CP) and lymph (CL) protein concentration were measured during 60 min in air and 120 min of WI (37 degrees C). Lymph flow in air averaged 0.96 +/- 1.0 (SE) ml/min. Lymph flow tended to decrease immediately in WI and was maintained at a level averaging 0.66 ml/min. CP/CL did not change significantly, whereas Hct fell significantly by 1.51 +/- 0.2% (Hct units) at 40 min of WI. Urine flow increased significantly to a maximum value of 1.5 +/- 0.5 ml/min at 40-60 min of WI compared with a mean value in air of 0.3 +/- 0.1 ml/min. The Hct and urine flow responses indicate that fluid shifted into the intravascular space during WI. Since lymph flow tended to decrease, the fluid shift in WI occurs across the capillary wall and not via lymphatic channels.

Sheep Fetus

A method was developed for chronic catheterization of the left thoracic lymph duct at the base of the neck in the sheep fetus, which did not disrupt the other major lymphatic vessels that join the venous circulation at the same location. The lymphatic catheter was connected to a catheter in a jugular vein when lymph flow was not being recorded, so that the lymph continuously returned to the fetal circulation. Special consideration of catheter size to minimize flow resistance and treatment to prevent clotting were required. Individual animals were maintained up to 17 days with lymph flow continuing. In 13 fetuses averaging 128 days gestation (term = 147 days) at the time of catheterization, lymph flow rate was measured for 1 h each day for the first 7 postsurgical days with an on-line computer technique that continuously calculated lymph flow rate. Lymph flow averaged 0.64 +/- 0.17 (SD) ml/min in fetuses weighing 2.3-4 kg and tended to undergo a nonsignificant increase with time. Lymph and plasma protein concentrations did not change with time. In individual fetuses, large spontaneous variations in lymph flow rate occurred over periods of several seconds to a few minutes. Analysis showed that these variations in flow rate were not associated with fetal breathing movements. Thus the present study describes a technique for studying the dynamics of lymph flow in the unanesthetized sheep fetus in utero over a time period limited primarily by the length of gestation. In addition, it appears that thoracic duct lymph flow rate in the fetus per unit body weight averages three to four times that in the adult.

The roles of the transvascular fluid flux and lymph flow in the distribution of extracellular fluid volume during angiotensin II (ANG II) hypertension were evaluated in 11 conscious dogs. Similarly, the factors regulating the distribution of plasma protein across the microvasculature were assessed. By the second day of ANG II infusion, the thoracic duct lymph flow had increased 58% above control, transcapillary fluid flux had increased 45%, and plasma volume, sulfate space, and interstitial fluid volume remained close to control. In addition, the thoracic duct lymph protein transport had increased 34%, and the accompanying increase in transcapillary protein flux prevented any change in plasma protein mass. Also, at this time, the lymph flow and protein transport from subcutaneous tissue in the hind limb were not increased, and the permeability-surface area product of this region decreased 40%. The origin of the increased thoracic duct lymph flow on day 2 probably was from the splanchnic bed. In conclusion, the increased lymph flow during ANG II hypertension compensated for the increase in transcapillary fluid flux, thus preventing edema formation.

Thoracic duct lymph flow and lymphocytes were first studied in 18 normal guinea pigs. Similar studies were then made on a) 25 guinea pigs placed in a decompression chamber at a simulated altitude of 14,000 ft for times ranging from 1 to 5 days, this being the period of "primary hypoxia" during which erythropoiesis is stimulated and polycythemia develops, and b) 25 guinea pigs exposed to primary hypoxia for 5 days, then kept in room air for times ranging from 1 to 5 days, this period of posthypoxic polycythemia being known as "rebound." By the end of rebound the polycythemia had almost disappeared. The flow of thoracic duct lymph increased significantly from a control level of 0.86 ± 0.21 ml/hr to 1.23 ± 0.1 ml/hr by the 5th day of primary hypoxia, and to a peak of 1.89 ± 0.23 ml/hr by the 3rd day of rebound, falling slightly to 1.56 ± 0.14 ml/hr by the 5th day of rebound, when it was still markedly above control level. The total cell content of the lymph also rose significantly, from 34.5 ± 10.3 x 106 lymphocytes/hr in the control animal to 59.1 ± 8.9 x 106 /hr on the 5th day of primary hypoxia, and to a peak of 93.8 ± 23.0 x 106 on the 3rd day of rebound.
