[Influence of simulated hypomagnetic environment in a far space flight on the rhythmic structure of rat's behavior].

Behavior of a group of rats was observed visually and tape recorded continuously from day 19 till the end of 25-d hypomagnetic experiments. Results were statistically processed with the help of Statistica 6.0, time series spectral analysis, and cosinor analysis.

[Reversible erythrocyte aggregation in patients with schizophrenia].

Reversible aggregation of erythrocytes was studied in 33 male patients with paranoid schizophrenia aged 23-48 years. Minimum and maximum solidity of erythrocyte aggregates, spontaneous aggregation half-period, amplitude of photometric signal, aggregation index and integral coefficient were evaluated by photometry. A significant (p < 0.

[Reversible erythrocyte aggregation in cancer patients].

Reversible aggregation of the peripheral blood erythrocytes was studied in patients with stages III-IV lung cancer and patients with stages II-III tumors of the head and neck (cancer of the tongue, larynx, and buccal mucosa). The parameters examined were as follows: U0 and Ud--minimal and maximal stability of aggregates, tau---red cell aggregation half-period, A--the amplitude of photometric signal (in mm) characterizing the count of erythrocytes, Ia--aggregation index, and K--integral coefficient. The findings indicate an appreciable intensification of reversible aggregation of red cells in cancer: a significant increase of U0, Ud, A, Ia, and K and decrease of tau.

[Reversible red cell aggregation in children with insulin-dependent diabetes mellitus].

Red cell aggregation has been studied by photometry in 47 children with insulin-dependent diabetes mellitus. The disease was associated with boosting of reversible red cell aggregation, which was most of all expressed during metabolic decompensation with ketoacidosis. When metabolic subcompensation was attained, this parameter did not completely normalize and still had to be corrected.
