The study on the necessary equipment to eliminate the suppressive immunosubstance in plasma of progressive cancer patients

Abstract

Recently we have examined the immunoresponse of cancer patients by use of recall antigen (PPD, PHA, Mumps, Candida, SKSD) and lymphoblastogenesis stimulated by PHA, Con A. By these study, extensive immunosuppressive effect was found especially in lung squamos cancer patients.
A new device which eliminate the immunosuppressive substance was made in our laboratory and basic clinical, experimental study have been tried.
Immunosuppressive substance of serum which contains only in a molecular weight of more than 7×10⁴ was found in squamos lung cancer, but not found in normal control group.
