Process of treating inflammation with human urinary thiol protease inhibitor

摘要

An anti-inflammatory agent comprising as an active component an inhibitor specifically inhibiting a thiol protease, which is obtained from human urine by extraction and purification. This agent has an action of inhibiting a disease caused by a thiol protease. This anti-inflammatory agent is prepared by a process in which a thiol protease inhibitor is extracted and purified from human urine by adopting in combination at least two treatments selected from a treatment with a molecular filter, a treatment with an ion exchanger, a treatment with an adsorber and an affinity chromatographic treatment.
