PONZ , F.

Sugar absorption by the small intestine has been studied in rat and hamster in vivo, with luminal perfusion, during 1 minute successive periods. Transport is calculated as the difference between absorption and diffusion. The diffusion component is evaluated in the presence of phlorizin or as absorption of sorbose. The resulting KT values for...

A simple technique to study intestinal absorption in vivo, a modification of that of SoLS and PONZ (34), is described. It uses a perfusi on pump, with or without recycling of the solution along the intestinal lumen, and allows the carrying out of a ser ies of successive absorption periods with high comparative value on the same...
