[Immunoenzyme detection of specific brain antigens as a criterion of the permeability of the hemato-encephalic barrier in rats following acute gamma irradiation]. / Immunofermentnaia detektsiia spetsificheskikh antigenov mozga kak kriterii pronitsaemosti gematoéntsefalicheskogo bar'era krys posle ostrogo gamma-oblucheniia.

The immunoenzyme detection systems for the measurement of the alpha-2 globulin of the brain (alpha 2M) and glial fibrillary acidic antigens (GFAP) were developed. These systems were used for the study of the penetration through hemato-encephalic barrier in rats subjected to gamma radiation. This method is recommended for the indirect evaluation of the hemato-encephalic barrier functional disorders.

[Elevation of the serum concentration of alpha- and beta-globulins and of a particular carcinoembryonic antigen by ultrasound exposure of liver tissue and CEA-active carcinomas]. / Die Steigerung der Serumkonzentration von alpha- und beta-Globulinen und speziell des karzinoembryonalen Antigens durch Ultraschallbestrahlung von Lebergewebe bzw. von CEA-aktiven Karzinomen.

The concentration of alpha- and beta-globulins in the serum can be increased by exposure of the globulin-producing tissue of the liver to ultrasound. The ultrasound intensities producing this effect are harmless according to our present knowledge. Especially the concentration of the globulin carcinoembryonic antigen in the serum can be increased significantly by exposure of CEA-producing carcinomas to ultrasound. There is to investigate the possibility of the early detection of CEA-producing tumors using a provocation test by way of increasing still normal spontaneous CEA-concentrations in the serum by insonation of body regions in question to significant pathologic serum concentrations.
