Abstract

The present invention is one kind snake venom cytozyme hemostatic containing blood coagulating factor, activator RVV-X and synergist snake venom thrombase. Preferably, the snake venom cytozyme hemostatic contains also serum albumin, for example human serum albumin. In addition, the present invention also discloses the preparation process and hemostatic use of high purity RVV-X.

Description

technical field [0001] The invention relates to a snake venom coagulase hemostatic drug, which contains a blood coagulation factor ten activator (RVV-X) and a synergist-thrombin-like enzyme (Thrombin-like Enzyme). More preferably, the hemostatic agent further contains serum albumin, such as human serum albumin. Background technique [0002] In 1934, Macfarlane et al. found that viper venom had a very significant coagulation effect. When it was diluted 1000 times, it could coagulate the blood of hemophiliacs in 17 seconds (see The Lancet, "DRS. MACFARLANE & BARNETT: HAEMOSSTATICPOSSIBILITIES OF SNAKE-VONOM" , Nov.3, 1934, pp. 985-987). It was used as local hemostasis for external use in some areas abroad in the early stage, such as hemostasis for pulling teeth (see The Lancet, "CLINICAL AND LABORATORY NOTES", Feb. 22, 1936, page 428), and use full poison, that is, no Stypven (Wellcome UK), the representative product of the isolated and purified primar...
