During the past years, knowledge has been accumulated concerning the components of the plasma kinin system and their interactions. Various workers described different kininogenases or kininogens, and some found evidences for distinct functions of such components present even in the same plasma. This led to the assumption of at least two kinin-forming systems in one plasma. In addition, there exists no agreement about the physicochemical and enzymatic properties of Hageman factor. It was tempting to consider the occurrence of more than one kind of contact factors. |
