Chicken meat labeled in vivo with radio-B12 was ingested by normal volunteers. The absorption, measured by the fecal excretion method, was similar to that reported for crystalline radiocyanocobalamin and for mutton, but exceeded that from eggs. Paren

The main purpose of this investigation was to study the assimilation of cyanocobalamin from fish. For this reason rainbow trout were injected with 57Co-vitamin B12 and sacrificed 2 to 3 weeks later. The radioactivity was found to be evenly distribute

Serum vitamin B12 (B12), maximal gastric acid output (MAO), and B12 absorption were determined in 82 subjects, age 32 to 85 years, who had normal absorption of radiocyanocobalamin. In 46 of the patients the gastric intrinsic factor (IF) was also meas

Patients who have undergone gastric resection and those with simple gastric hypochlorhydria and achlorhydria may have low serum B 12 concentrations with normal absorption of radiocyanocobalamin. Impaired assimilation of food vitamin B 12 , but not of

The effect of time and temperature on the intrinsic factor (IF) activity of acid in native human gastric juice was investigated using a standardized radioimmunoassay. The following observations were made on the loss of IF activity: at body temperatur

A new method for the determination of the absorption of vitamin B12 has been described using measurement of radioactivity in the blood or plasma after the ingestion of physiologic test doses of Co60 labeled vitamin B12. Although doses of 1.0 µc. (0.
