Vitamin B12 Activity in Developing Chicken Eggs

Erythrocyte Vitamin B12 Activity in Health, Polycythemia, and in Deficiency of Vitamin B12 and Folate

T HERE HAS BEEN RELATIVELY LITTLE WORK on the estimation of erythrocyte vitamin B12 activity in man, and consequently there are few reports of its activity in disease states. Sobotka et al.1 reported low levels in four cases of pernicious anemia ( P. A. ) , using E. gracilis and 0. maihamensis. This was confirmed by Biggs et al.,2 who also reported the levels found in treated cases of polycythe...

Identification of immunoglobulins in chicken eggs and their antibody activity.

Oral vitamin B12 versus intramuscular vitamin B12 for vitamin B12 deficiency.

BACKGROUND Vitamin B12 deficiency is common, and the incidence increases with age. Most people with vitamin B12 deficiency are treated in primary care with intramuscular (IM) vitamin B12. Doctors may not be prescribing oral vitamin B12 formulations because they may be unaware of this option or have concerns regarding its effectiveness. OBJECTIVES To assess the effects of oral vitamin B12 vers...

of glycosaminoglycans in chicken eggs

Glycosaminoglycans (GAGs) have numerous applications in the fields of pharmaceuticals, cosmetics, nutraceuticals, and foods. GAGs are also critically important in the developmental biology of all multicellular animals. GAGs were isolated from chicken egg components including yolk, thick egg white, thin egg white, membrane, calcified shell matrix supernatant, and shell matrix deposit. Disacchari...
