[Amylase isoenzyme analysis in an amylase-producing tumour (author's transl)].
The plasma and pulmonary tumour are studied in a patient with lung metastasis. An abnormal and neuraminidase-sensible isoenzyme is noted both in plasma and tumour. Homogenates obtained from the tumour by two different mechanic disruption procedures denote an easier liberation for the salivary type isoenzymes than for pancreatic types. It is suggested that the salivary enzymes are synthesized in the cytoplasm during many inflammatory processes and secreted without cellular necrosis.
