A case of ruptured hepatoma followed by elastase-induced disseminated intravascular coagulation.
In the present study, the first case of ruptured hepatoma followed by disseminated intravascular coagulation is reported. An elastase-like enzyme which possessed elastolytic and caseinolytic activities was confirmed from patient plasma. On the other hand, no elastase activity was detected in the plasma of patients with hepatitis, liver cirrhosis or hepatoma without disseminated intravascular coagulation. The patient plasma did not possess H-D-Val-Leu-Lys-p-nitroanilide hydrochloride, succinyl-L-alanyl-L-alanyl-p-nitroanilide, and pyro-Glu-Pro-Val-p-nitroanilide amidolytic activities. However, when chromatographed on Sephadex G-200, the presence of low-molecular weight plasminogen was confirmed. Its molecular weight was approximately 52,000. A slight decrease of alpha 2-plasmin inhibitor was noted, but no decrease of alpha 2-macroglobulin was detected.
