[Heparin-histamine complex, its physico-chemical and biological properties].

Complexes between heparin and histamine at various ratio exhibited various physiological activity. The complex containing heparin-histamine at the ratio of 6:1, 10:1 or 15:1 showed anticoagulation, antipolymerization and nonenzymatic fibrinolytic effects. The complex dissociated in circulation within 90 min after its administration. This complex effected also the rheologic properties of blood.
