PROBLEM TO BE SOLVED: To provide a method for treating a vascular endothelial dysfunction relating or contributing to quite a lot of diseases and disorders.SOLUTION: This invention provides a method of treating a vascular endothelial dysfunction at a site in a subject requiring a treatment. The method includes the administration to the subject of a therapeutically effective amount of thrombin receptor (NPAR) agonist activated non-proteolytically. The site is not an artery damaged by angioplasty, chronic skin ulcer, a site requiring bone induction, nor a site requiring cardio-revascularization.

摘要:
Production of proteins from pro-proteins comprises contacting a pro-protein solution with a protease and a solid support that has a higher affinity for the proteins than for the pro-protein or its functionally inactive degradation products, whereby the pro-protein is proteolytically cleaved to form the protein, which is selectively separated by adsorption on the solid support. Also claimed are: (1) a hirudin or a hirudin fragment or derivative coupled to a solid support; (2) a protein complex produced by the above process, comprising a protein adsorbed on a solid carrier, and (3) an apparatus for carrying out the above process, comprising a container containing a protease directly connected to a container containing a solid support.
