[Research on the immunological and biochemical structure of tumors of the prostate gland].

The study of IgA, IgG and IgM immunoglobulins obtained from tissues of prostate adenoma and adenocarcinoma, as well as of homogenates by electrophoresis in polyacrylamide gels, revealed the presence, the amount and the different conformation of protein fractions in the adenoma and in the adenocarcinoma. Inflammatory processes do not play a significant role. Comparative measures of nucleic acids and of SH groups suggest the existence of molecular mechanisms interpreted in the light of ageing processes.
