Abstract:

In anesthetized rats, the activity distribution of intravenously administered synthetic human gastrin I, labelled with 123 I, was recorded externally by a gamma camera. In intact rats activity was found to accumulate in the kidneys and later in the stomach. After bilateral nephrectomy, the gastric apperance of activity was delayed. In both cases, the gastric activity is considered to emanate not from intact 123 I-gastrin but from free iodide, split off during gastrin degradation. The renal accumulation of gastrin in intact animals as well as the delayed gastric uptade of iodide in nephrectomized animals support the hypothesis that the kidneys are important organs for gastrin metabolism.
