title: Difructose anhydrides III and IV equally promote calcium absorption from the luminally perfused rat small intestine.
abstract: We examined the effects of di-D-fructose anhydride (DFA) III and IV on Ca absorption in luminally perfused segments of the small intestine in anesthetized rats. The calcium absorption rate with perfusion of 10 mmol/l CaCl2 was similarly increased by addition of 100 mmol/l DFAIII or IV, and these promotive effects of both DFAs were pronounced at perfusion rate of 0.15 ml/min than at 0.3 ml/min. The promotive effects were higher in the duodenojejunum than in the ileum.
