A possibility of the use of a radionuclide tubeless rapid method for measuring gastric content proteolytic activity (GCPA) with the help of a protein (gelatin) RP containing capsule was demonstrated in experiments in vitro. There was correlation between the time of dissolution of RP containing capsules and GCPA determined after Mett's method. Reference time intervals were established for normal, raised and lowered proteolytic activity. The method was shown to be physiological, simple and time-saving.
体外实验证明了一种利用含放射性核素的无管快速方法，借助含蛋白质（明胶）的放射性核素胶囊来测量胃内容物蛋白水解活性（GCPA）的可能性。含放射性核素胶囊的溶解时间与采用梅特氏法测定的GCPA之间存在相关性。确定了正常、升高和降低的蛋白水解活性的参考时间间隔。该方法显示出具有生理性、简单且省时的特点。
