Changes in the fluid compartments and dry weights of reimplanted dog lungs

dry weights of reimplanted dog lungs. J. Appl. Physiol. 40(6): 962-970. 1976.-We studied changes in fluid compartments and dry weights of reimplanted lungs of dogs during the first 6 wk after operation. Excision and reimplantation caused a large increase in lung weight. The increase in weight was maximal 3 days after operation, was proportionately greater in the upper middle lobe than in the lower lobe, and was principally due to increased extravascular water. Dry weight and noncirculating red cells (measured by subtracting “‘CT-labeled red cell mass from total red cell mass as measured by hemoglobin extraction) also increased within 3 days after oper-ation. Lung weight and extravascular water decreased pro-gressively after 3 days and were normal in 6 wk. Chromated blood mass remaining within excised, passively drained lobes did not change at any stage postoperatively. Three days afte
