The value of an antitryptic blood serum sample for the recognition of malignant lesions of the digestive tract

As in 1907, Myriyeg and Dossman discovered a new property of blood serum to inhibit the proteolytic action of leukocytes and trypsin, so to speak, the antiproteolytic, or antitripsic property of blood serum, the latter underwent numerous observed directions. Studies, especially of the late time, have established both the amount of this anti-body in the blood of normal people, and its fluctuations in various pathological states of the body. At the same time, it turned out that from all painful processes with the greatest constancy of an increase in antitrypsin, the blood of cancer patients possessed the greatest constancy.
