Abstract
A new method for assessment of the intestinal secretion rate of immunoglobulins and other proteins is evaluated. The procedure involves a combination of luminal perfusion of a defined intestinal segment and analysis of the aspirated perfusates by rocket immunoelectrophoresis. The technique is sensitive and reliable. A material from the normal human jejunum and ileum is presented. The metod is proposed as an investigative tool for characterization of the local immunological system of the small intestine.
