Fibrinolysin
（重定向自Fibrolan）
Fibrinolysin is an enzyme derived from plasma of bovine origin or extracted from cultures of certain bacteria. It is used locally only and exclusively together with the enzyme desoxyribonuclease (extracted from bovine pancreas). Fibrinolysin and desoxyribonuclease both act as lytic enzymes. The combination is available as ointment containing 1 BU (Biological Unit) fibrinolysin and 666 BUs desoxyribonuclease per gram.
