To investigate the intestinal absorption of parotin, <SUP>125</SUP>I-labelled parotin was added in the mucosal side of the sac of rat everted intestine and incubated for 1 hr. Parotin seemed to be transmitted through the intestinal wall into the serosal fluid, because the non-diffusible <SUP>125</SUP>I-bound substance which reacted with the anti-parotin rabbit serum was detected in the serosal fluid. The amount of <SUP>125</SUP>I-macromolecule in the serosal fluid which was estimated from the radioactivity was in good agreement with that of the immunoreactive substance in the fluid determined by a single radial immunodiffusion, and the concentrations of these substances in the serosal fluid were about 1/5 of parotin concentration in the mucosal fluid.<BR>Apart from this, <I>in situ</I> mesenteric perfusion was performed on the rats which were administered parotin and <SUP>125</SUP>I-labelled parotin in the ligated jejunum. The perfusate was collected from the mesenteric vein for 2 hr, and <SUP>125</SUP>I-bound macromolecule which corresponded to 3.4% of the administered <SUP>125</SUP>I-labelled parotin was found in the perfusate. There was an immunoreactive substance with the anti-parotin serum in the perfusate, too.<BR>From these results, it was inferred that about 3% of parotin given into the intestine was transmitted into the mesenteric blood vessels.
