6-10
Deficiency of this vitamin (cyanocobalamin) usually occurs when the absoprtion process is interrupted by lack of ability to synthesize ______ factor, disease, surgery, or infection. The stomach secretes a protein known as intrinsic factor, which carries cyanocobalamin to the ileium, where ti is absorbed. Therefore, the intestinal absorption of cyanocobalamin is dependent uponn the presence of intrinsic factor.
intrinsic
Some individuals lack the ability to synthesize intrinsic factor. As a result, these people are cyanocobalamin deficient and develop _____ anemia.
pernicious
Cyanocobalamin absorption may also be decreased when there is a chronic overgrowth in intestinal bacteria or _____, and the bacteria or parasites utilize the vitamin before intestinal absoption can occur.
tapeworm
Cyanocobalamin is available in tablets and injectable solution.
no answer
__________ (alpha-Redisol, Hydrobexan) is an injectable vitamin preparation that is longer-acting than cyanocobalamin because it is highly bound to proteins. It has no significant advantage over cycnocobalamin in the treatment of pernicious anemia.
Hydroxycyanocobalamin
Chronic heavy _____ intake (for more than 2 weeks) may produce malabsorption of cyanocobalamin.
alcohol
The RDA for _____ ____ can be satisfied by including green leafy vegetables and meat in the diet.
folic acid
A dietary ____ of folic acid frequently occurs because people do not adequately supplement their diet with vegetables. In addition, even well-balanced diets become folate deficient because the heat required for canning and cooking destroys folic acid
deficiency
_____ is essential for cell growth and reproduction because it is necessary for protein synthesis. It is utilized in the synthesis of thymidine, an essential element in the nucleoprotein DNA. Also, synthesis of amino acids requires an active form of this known as FH.
Folic Acid
Folic acid and cyanocobalamin deficiencies produce identical ____.
anemiasolic
Folic acid is approved for use in ______ anemia due to folate deficiency.

Drug interactions with folic acid may result in decreased absorption of folate or decreased productiion of FH4. ____ such as phenytoin (Dilantin), primidone (Mysoline), barbituates, and oral contraceptives interfere with the intestinal absorption of folic acid by an unknown mechanism. This decrease in folic acid absorption infrequently results in clinically significant megaloblastic anemia.

Certain drugs, such as methotrexate (antineoplastic), tremethoprim (septra), and pyrimethamine (antimalarial) block the formation of FH4 because they inhibit the enzymes that convert _______ to tetrahydrofolic acid.
folic acid
________ is a protein normally produced by the kidneys that participates in red blood cells homeostasis. Responding to changes in tissue oxygenation, it stimulates production of red blood cells in the bone marrow. This provides more vehicles to transport oxygen to the tissues, thus improving oxygenation.
