Jejunal and cecal 3-oxy-methyl-D-glucose absorption in chicken using a perfusion system in vivo
Abstract
3-oxy-methyl-D-glucose (3-OMG) absorption by jejunum and caecum has been studied in the domestic fowl in vivo, with luminal perfusion, during 5 min periods. The diffusion component was evaluated in the presence of phloridzin (10(-3) M) that inhibits the active transport mechanism. Kd of jejunal and cecal diffusion of the monosaccharide have been calculated, showing a similar value. The Kt and Vmax of 3-OMG absorption were calculated using a graphical method for the two intestinal segments. The caecum showed a lower Kt and Vmax than the jejunum did.
