Reversal of folate malabsorption in tropical and non-tropical sprue by calf jejunum.

In eight patients with folic acid malabsorption the malabsorption was reversed only when a combination of either 250 mg. of lyophilized human jejunal juice or 5 g. of lyophilized calf jejunum with 5 mg. of synthetic folic acid was fed; calf liver was ineffective. The factors in calf jejunum that re-established folic acid absorption were heat-stable and did not form polyglutamyl folates on previous incubation with folic acid.
