[The significance of cytochemical studies of the metals in blood neutrophilic granulocytes in the diagnosis of lung diseases].

Peripheral blood smears from healthy persons and patients with pneumonia and pulmonary tuberculosis were used for a cytochemical study of metals in neutrophils with the help of dithisone and chlortetracycline. The content of metals in these cells was increased in pneumonia and active tuberculosis, but was normal or decreased in non-active pulmonary tuberculosis. It is concluded that cytochemical reactions for metals may be used in the diagnosis of pulmonary diseases.

Dynamics of the temporal parameters of sensorimotor reactions as a function of movement type in man.

An investigation consisting of two series was carried out on nine healthy male subjects, age 20-24 years. In the first series, a warning signal and then four symbols which required a simple or a complex reaction were presented sequentially on a display screen. In the second series, asterisks were presented instead of the symbols. The sequence of reactions was performed from memory. The results of the investigations made possible the identification of two specific features: a significant decrease in RT in the series of reaction from memory, and a successive decrease in RT with a decrease in the number of the remaining signals in the block of signals. In the first series, the RT decreased successively by 35-40 msec, and in the second, by 16-20 msec. It is hypothesized that the difference in RT between the series characterizes the time of analysis of one signal, and the difference, on the other hand, in the RT within the limits of a single block in the second series characterizes the time for the retrieval from memory of the motor program.

[The assessment of the subjective second by using the "individual minute" test].

Correlation of the two characteristics of the "individual minute" test with age and sex of the subjects was examined in 151 persons. Close correlation was observed between the first (counting in the course of 60 s) and the second (counting time up to 60 s) modes of testing, but not between the two modes of testing and age and sex. Results are discussed from the viewpoint of the existence of the common system of time interval estimation the method of their quantum organization being used in different investigation modes.

[A correlation of EEG characteristics of pregnant women with the level of their anxiety].

It has been shown that the EEG of pregnant women with high anxiety level is characterized by a lower occipital alpha and theta rhythm spectral power if compared to the EEG of women with low anxiety level. The frequency of the alpha rhythm of their EEG was reliably higher. Pregnant women with high anxiety level with a pregnancy interruption threat diagnosis have an essentially lower occipital alpha rhythm spectral power than women of this group without such a diagnosis. And vice versa, the occipital alpha rhythm spectral power in the EEG of pregnant women with low anxiety level with a pregnancy interruption threat diagnosis is essentially higher and its frequency essentially lower than the EEG of women without that diagnosis. The data received are interpreted as a change in hormone regulation during the pregnancy period, as well as psychogenic influence on the pregnancy.
