Disorders of cobalamin (vitamin B12) absorption and transport
Abstract:
Highly specialized mechanisms are required for transporting cobalamin (vitamin B12) into and out of mammalian cells. This review describes the key role of the cobalamin-binding proteins in meeting the stringent requirements for transport of this essential nutrient. Also summarized are the various defects capable of impairing intestinal absorption and transcellular transport of cobalamin. Elucidation of these defects proved crucial for our current understanding of normal cobalamin transport mechanisms.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
