[Comparative dimensions of propriospinal neurons of different structuro-functional groups in the cat].

Profile areas of somata and proximal dendrites and conventional diameters (c.d.--diameter of a circle equiareal to this profile) of descending propriospinal interneurons labelled by horseradish peroxidase were measured in cat spinal cord.

[Biochemical aspects of the interaction of the malarial parasite, Plasmodium berghei, with erythrocytes of the host].

Mice erythrocytes, infected with Plasmodium berghei, were studied as a model of integrated cell system "parasite-host erythrocytes". The rate of blood oxygenation, content of methhemoglobin and methhemoglobin reductase activity maintained at the initial level up to the lethal outcome of the infectious process. A steady-state kinetics of glycolysis was studied in the impaired erythrocytes by means of automatic potentiometric titration of lactic acid during incubation of the cells.

[Study of IgE by thermistography].

The authors studied the possibilities of applying thermistography to the determination of IgE in human blood serum. It was shown that IgE is thermolabile, precipitating at the equivalent antigen/antibody ratios and at pH 5.5-7.

[Reaction of inhibition of macrophage electrophoretic mobility in differential diagnosis of carcinomas].

The reactivity of the lymphocytes from 40 carcinoma patients and 19 patients without detectable malignancies was tested by means of the macrophage-electrophoresis-mobility (MEM) test exposing lymphocytes from one individual to a large spectrum of antigenic preparations. Besides the encephalitogenic protein (EP) and the carcino-embryonic antigen (CEA) hypertonic KCl-extracts from human cancer and normal tissues were used as antigens to be tested. When performed in such a complex manner, the MEM-test resulted in characteristic reaction patterns allowing one not only to discriminate between cancer and noncancer, but also to draw a conclusion in which organ a carcinoma has arisen.
