[Radionuclide method of determining the proteolytic activity of the stomach contents (clinical studies)].

The authors described clinical testing of a new tubeless radionuclide rapid method for measuring gastric content proteolytic activity (GCPA) using a protein (gelatin) capsule filled with a radiopharmaceutical (RP). The solution time of a capsule with a radiotracer determined by its clearance, corresponded to GCPA measured after Mett's method. The testing has shown that the above method is physiological, causes no complications and unpleasant sensations in patients, is simple to perform, and can be recommended for a wide clinical use in gastroenterology.
