Vitamin B 12 excretion by the rat small intestine. 1969

C A Loehry, and B Creamer

Two phases of intestinal excretion are demonstrated after a parenteral dose of (58)Co vitamin B(12). The first phase was maximal immediately after injection, and was related to plasma radioactivity. The second phase was delayed 36 to 48 hours and was related to labelled cells reaching the tips of the villi. The loss of vitamin B(12) through increased exudation and rapid cell exfoliation together with failure of reabsorption may play a part in the deficiency state seen in the coeliac syndrome.

D005122	Exudates and Transudates	Exudates are fluids, CELLS, or other cellular substances that are slowly discharged from BLOOD VESSELS usually from inflamed tissues. Transudates are fluids that pass through a membrane or squeeze through tissue or into the EXTRACELLULAR SPACE of TISSUES. Transudates are thin and watery and contain few cells or PROTEINS.
