title: [Activation by means of various adsorbents. (Contribution to the mechanism of contact activation of the blood coagulation process)].
abstract: 20 different adsorbing substances were examined for the purpose of determining physico-chemical parameters influencing the contact activation in the partial thromboplastin time (PTT). In the course of these examinations the prerequisites for the process under way were found to exist in a low adsorbing activity of the substance used as a surface and in the reversibility of adsorption. The effect activating the contact will depend on surface conditions and to a lesser degree on its size. An even crystal structure and the size of particles will have a positive influence on the surface properties and thus on the effect activating the contact.
