Abstract:
Plasma levels of prekallikrein (PK), plasminogen (PLG), fibrinogen (FIG) in 84 cases of malignant tumor were studied with an advanced method.Each item was measured 100 times. The results showed that PK, PLG were significant lower than those of control subjects (P0.01), it were low in patients with the cancers of lung, the gastroenteric cancers and leukemias. The more severe the disease condition, the lower was the levels of PK, PLG. It clearly showed that the balance between coagulation and anti-coa-gulation systems was upset in patients with malignant tumor.
