Quick- and slow-release iron: a double-blind trial with a single daily dose regimen.

In a double-blind trial the response to treatment with Ferro-Gradume (a slow-release preparation of ferrous sulphate) has been compared in the same individuals with the response to ferrous fumarate in a single daily dose regimen using a similar dose of iron. No significant difference was found in the therapeutic response or in the incidence of side-effects between the two preparations.

Absorption of therapeutic preparations of iron measured with a whole body counter.

The Oxford Whole Body Counter was used to measure absorption from various therapeutic preparations of iron in five groups of subjects. Succinic acid enhanced absorption of iron when added to a solution of ferrous fumarate, but not when given with tablets of ferrous fumarate or ferrous sulphate. Ferrous fumarate plus ascorbic acid was absorbed better than ferrous fumarate alone but no better than ferrous sulphate. The addition of ascorbic acid and succinic acid to tablets of ferrous sulphate did not enhance absorption significantly.

Iron absorption and blood loss in patients with hiatus hernia.

Iron absorption was measured in 28 patients, 19 of whom were anaemic. The mean absorption in the anaemic patients was 39% and in the non-anaemic patients 8%. Gastrointestinal blood loss was then measured in 26 of these patients. The mean estimated blood loss in the anaemic patients was 15 ml. a day and in the non-anaemic patients 3 ml. a day. In 16 of the 19 anaemic patients symptoms of anaemia were either the sole or the major complaint.

A comparison of two methods for the immunoassay of intrinsic factor.

The intrinsic factor content of 263 samples of gastric juice was determined by immunoassay using charcoal absorption and by immunoelectrophoresis on acrylamide gel. There was good correlation between the results of the two techniques and, with a few exceptions, both made it possible to predict which patients would have malabsorption of radioactive vitamin B(12). Of the two methods, immunoassay using charcoal absorption generally gave the higher readings. Further study showed that this could not be attributed to the recognized difference in the principles of the two methods but that it was more likely to be due to the dissimilarity of the experimental conditions.
