A highly sensitive radioimmunoassay capable of measuring α 1 -fetoprotein (AFP) has been
developed. AFP was detected in the plasma of all the 105 controls (2·3±1·2 ng. per ml.). …

Three patients with dyspeptic symptoms who were being treated with the H 2 -receptor
blocking drug, cimetidine, were later found to have gastric carcinoma. It was not possible to …

Thirteen patients with chronic pepticulcer disease (two with duodenal ulcer and eleven with
recurrent ulceration after previous gastric surgery) were studied. In each patient plasma-…

Purified human urogastrone was given by intravenous infusion to 12 normal volunteer
subjects and measurements made of gastric acid, pepsin and intrinsic factor secretion, and of …

Lower oesophageal sphincter pressure and fasting plasma gastrin and progesterone were
measured in 31 women in the last trimester of pregnancy and in 10 healthy female control …

A sensitive, specific and precise immunoradiometric assay for ferritin has been developed.
Ferritin was measured in the serum of 160 hospital controls, 101 females (118+/-9 mug/l) and …

Our earlier observation that pentagastrin is a calcitonin (CT) secretagogue was confirmed
and extended to include both synthetic human gastrin I and pure porcine gastrin II. The latter …

1. A radio‐immunoassay for gastrin has been developed using partially purified porcine
gastrin to raise antibodies and highly purified natural porcine gastrin I for radio‐iodination with …

The role of calcitonin (CT) in postprandial calcium homeostasis and the possibility of a
gastroentero-thyroid C-cell system was studied in young pigs. When pigs were fasted for more …
