title: [Tryptic enzymes in the differential diagnosis of inflammatory diseases of the colon (author's transl)].
abstract: Inflammatory diseases of the colon can be differentiated by means of their chymotrypsin A excretion in the stool. In proctosigmoiditis and a group of comparable gastroenterological cases, the mean excretion level is between 170 and 200 mug per gram of stool. The chymotrypsin A level in proctocolitis, on the other hand, is significantly higher in all stages and increases with increasing activity of the disease. This brings a further diagnostic criterion to the clinical and endoscopic differences between proctosigmoiditis and proctocolitis (colitis ulcerosa). The fundamentally different behavior in the excretion of chymotrypsin A in the stool supports the hypothesis of two diseases differing from each other.
