Effects of Vitamin B12 in Neonates and Young Infants
Vitamin B12 (cobalamin) is an essential coenzyme for nucleic acid synthesis. Animal protein is the major dietary source of vitamin B12. Deficiency of vitamin B12 leads to megaloblastic anemia, degeneration of the brain, spinal cord, peripheral nerves, and abnormalities of epithelial tissues. Two factors are necessary for the cure of megaloblastic anemia: one in food (extrinsic factor) and one i...
متن کاملStudies on the 57Co vitamin B12 plasma level absorption test.
Results of the (57)Co vitamin B(12) plasma level absorption test are described in 163 patients. The use of intramuscular carbachol with the test and the presence or absence of current vitamin B(12) therapy did not affect the test results. Injection of 1,000 mug of unlabelled vitamin B(12) during the test augmented plasma levels in patients with normal absorption but tests without this injection...
متن کاملAntibacterial Activity of Lincomycin and Pristinamycin: a Comparison with Erythromycin.
The secretion of gastric intrinsic factor was studied in normal subjects and in hospital patients. A considerable amount of intrinsic factor was present in gastric juice secreted in the absence of any stimulant, and this amount was normally far in excess of that required for the absorption of dietary vitamin B12' Histamine and insulin were equally effective as stimulants of gastric-intrinsic-fa...
متن کاملHolo-Transcobalamin Concentrations and Transcobalamin Saturation Reflect Recent Vitamin B12 Absorption Better than Does Serum Vitamin B12
Background: We evaluated whether measurement of vitamin B12-saturated transcobalamin (holo-TC) concentrations or TC saturation (holo-TC:total TC) reflects active vitamin B12 absorption in healthy individuals and patients after vitamin B12 intake. Methods: We obtained blood samples from 31 healthy individuals (age range, 25–57 years) before (days 1 and 0) and after (days 1, 2, and 6) oral admini...

A dual isotope vitamin B12 absorption test in which vitamin B12 is given both in aqueous solution and bound to protein (chicken serum), was evaluated in 26 controls and 68 patients with subnormal serum vitamin B12 concentrations (19 with pernicious anaemia, 13 with iron deficiency, seven after partial gastrectomy, seven with malabsorptive states, five with folate deficiency, four with chronic a...
