[Animal experiments with ligation of intestinal segments to study absorption of alpha-amino-iso-butyric acid by intestinal mucosa of foetus (author's transl)].

The authors developed an animal model with ligation of intestinal segments of guinea pig foetuses. Evidence was found to the effect that amino acids were absorbed in high concentrations by foetal jejunum. A peculiar aspect, additionally detected, was relating to the capability of foetal intestinal mucosa to absorb large-molecular substances, such as inulin.
