Studies on proactivator from the paranasal mucous membrane in chronic sinusitis.
We succeeded in differentiating the proactivator (PA) in tissue extract of paranasal mucous membrane with chronic sinusitis by the gel filtration technique. Furthermore, the results demonstrated that PA in the tissue extracts of the paranasal mucous membrane with chronic sinusitis and antrochoanal polyp was unrelated to the antigenicity of plasminogen. In particular, it was clarified that the tissue extract of antrochoanal polyp as a source of PA was not related to the antigenicity of plasminogen.
