Intrinsic Factor

Partial Intrinsic Bayes Factor

We have developed a new model selection criteria, the partial intrinsic Bayes factor, which is designed for cases when we select a model among a small number of candidate models. For example, we can choose only a few candidate models after exploring scatter plots. Based on this motivation, the partial intrinsic Bayes factor is developed. By simulation study, we showed that PIBF performs better ...

Intrinsic factor antibody tests.

The sensitivity of methods to detect antibodies to intrinsic factor was assessed. Five sera of known antibody content were tested in 31 laboratories and 30 sera from patients with pernicious anaemia were tested in one laboratory. Five non-commercial methods and two kits for type I antibodies and one non-commercial method for types I and II antibodies are in current use. Differences in sensitivi...

Intrinsic factor secretion after vagotomy.

The intrinsic factor (IF) output during basal and Histalog-stimulated gastric secretion has been estimated in two series of patients with chronic duodenal ulcer before and 3 months or more after treatment by either highly selective vagotomy or truncal vagotomy and pyloroplasty. The effects of the two different vagotomy operations appear to be virtually identical and each produced significant re...

Intrinsic factor in tropical sprue.

Criteria used to establish the diagnosis of tropical sprue were previously published.5 Twenty-one of the patients with sprue and four of the normal subjects were Puerto Rican. The patients with sprue ranged in age from 15 to 74 and the normal groups from 25 to 56. Treated patients were receiving folic acid orally, 5 mg. daily. Gastric juice was collected before and for 90 mm. after subcutaneous...
