Time of exchange of 131I-labeled albumin between plasma and peripheral lymph in man.
The passage from blood to peripheral lymph of 131I-labeled human serum albumin has been studied in 6 male patients (30-70 years) with malignancies without metastases. On the first day the concentration of radio-labeled albumin in the blood was kept almost constant by repeated i.v. injections. Lymph was collected continuously from a cannulated subcutaneous lymph vessel on the leg. Two hours after the first i.v. injection of radiolabeled albumin the lymph contained significant amounts of radioactivity in all patients. Equilibrium between radioactivity in blood and lymph was reached after 26 hrs. This indicates a long "wash out time" of unlabeled protein in the interstitial tissue from where lymph has been sampled.
