Changes of prekallikrein in the cases with DIC were investigated, i.e., DIC cases including disseminated metastasis of gastric cancer, acute promyelocytic leukemia and endotoxin shock. Therefore, the trigger substances for this paper were the pathologic cells of the leukemia, the cultured well differentiated adenocarcinoma cells and endotoxin. (1) The lysates of the pathologic cells of the leukemia and the cultured cells showed prekallikrein activation. Endotoxin showed prekallikrein activation via factor XII. (2) Serine proteases (factor Xa, thrombin, plasmin and trypsin) activated prekallikrein in the plasma and the purified prekallikrein. (3) Antithrombin III, aprotinin and FOY inhibited prekallikrein activation. Antithrombin III was promoted by heparin in its inhibitory effect.

Factors of coagulation and fibrinolysis have been evaluated in 15 patients with untreated acute nonlymphoblastic leukaemia (ANLL). 10 patients had major bleeding (MB) and 6 had laboratory signs of DIC. 5 patients went into complete remission (CR). Antithrombin III (AT III) was decreased in 7 patients, antiplasmin (AP) in 9, fibronectin (FN) in 6 and factor XIII in 4/12. The ratio between factor VIIIR:Ag and factor VIII:C was over 2.0 in 11 patients, and high values were especially seen in patients with MB and patients with DIC. Spontaneous proteolytic activity, measured with S-2288 was increased in 3 patients who all had MB, and none of whom achieved CR. 2 patients with promyelocytic leukaemia (M3) had low fibrinogen and AP, high FDP and normal AT III, speaking for primary fibrinolysis, which in addition to proteolytic enzymes in the blast cells are important contributing factors regarding MB in ANLL.
