title: [Acid-base changes across the rat jejunum, in vitro (author's transl)].
abstract: Everted sacs of rat jejunum are able to adjust to near 6.5 any solution whose pH is situated between 5.5 and 9.5. Beyond these limits the adjustment becomes incomplete. Changes in PCO2 and total CO2 associated with changes in mucosal pH-values suggest that bicarbonate or CO2-movements toward the jejunal lumen involved in this adjustment process are predominant.
