✦ Synopsis

The resorption of porphyrin from the duodenum was studied in rats using a solution of 14C-tagged haemoglobin. The tagging was carried out by incubation of duck erythrocytes with laC-Delta-ALA, resulting in an incorporation quotient of 12~ A comparative test with 14C-glycine resulted in a 270~ higher incorporation quotient. The tagged haemoglobin was given by duodenal garage and the bile collected by a bile-duct-fistula. The resorption rate for haemoglobin or porphyrin was calculated from the total radioactivity found in the bile. It was 2.5--3.2% of the applied dose.
