[Polarographically active fraction of alpha 1-unstable glycoprotein in the blood serum during the malignant process]. / Poliarograficheski aktivnaia fraktsiia al'fa 1-nestabil'nogo glikoproteina v syvorotke krovi pri zlokachestvennom protsesse.

The simple method of polarographical testing of the peripheral blood serum is recommended as a part of the complex cancer diagnosis for the evaluation of the effectivity of cancer treatment and for the mass preventive examination. This method modified by I. A. Pelishenko (POISK-test) has permitted detecting a protein substance in the serum of cancer patients as well as in the serum both of the rats bearing Pliss sarcoma and in the serum of the irradiated dogs. It was proved that this protein indicates the presence of malignancy and represents polarographically active fraction of the alpha 1-unstable glycoprotein. This substance was designated as "Informative Pelishenko Protein" (IPP), and may be revealed by the polarographic indicator (IPM-01) made in Leningrad.
