[Biological activity of electrochemically activated solutions obtained in a diaphragm electrolyser].

The biological activity of the catholyte and anolyte of bidistilled water in experiments with the germination of wheat grains in the period from March to May has been studied. The activity of solutions, which was characterized by the grain germination index, was high at the beginning of the period, then it gradually decreased and was equal to zero at the middle of the period; at the end of the period it gradually increased almost to initial values. It has been established that the effectiveness of bidistilled water anolyte was as a rule higher than that of catholyte throughout the observation period. At the beginning and end, the stimulating effect of anolyte was 5-5.5 times greater than that of catholyte. The seasonal changes in the biological activity of M 9 medium catholyte were compared with those of bidistilled water anolyte and catholyte. The stimulating effect of M 9 catholyte was estimated by changes in the growth of E. coli cells. The stimulating effect, which was estimated from an increase in the optical density of cell suspension in the initial period at a cultivation temperature of 20 degrees C was 55-60% relative to control (untreated medium). Then it decreased almost to zero in the middle of the period to increase again approximately to the initial values. The assumption has been made that the physicochemical causes of the influence of catholyte and anolyte of bidistilled water on wheat grains and of the culture medium catholyte on E. coli cells are of different nature.

[Analysis of the effects of low-intensity intermittent and continuous electromagnetic fields on behavioral acts in the mice].

The fact of modulating influence of low-intensity electromagnetic field on the behavioral acts in mice was established. The dependence of mice behavior on the modulating frequency, electromagnetic field parameters (intermittent or continuous) and on the time of adaplive reaction was found.

[The delayed effects of modulated and non-modulated electromagnetic field on epileptiformic activity in rats]. / Otdalennye posledstviia deistviia modulirovannogo i nemodulirovannogo elektromagnitnogo polia na epileptiformnuiu aktivnost' krys.

The modifying influence of the weak electromagnetic field on the development of the audiogenic spasmodic activity in rats was shown. The decrease of lifetime of experimental rats exposed to electromagnetic fields with different parameters and development of tumours (in one set of experiments) was found.

[The dynamics of the manifestation of behavioral audiogenic seizure activity in rats under the action of a modulated and a nonmodulated electromagnetic field]. / Dinamika proiavleniia povedencheskoi audiogennoi sudorozhnoi aktivnosti krys pri deistvii modulirovannogo i nemodulirovannogo élektromagnitnogo polia.

It was shown that the electromagnetic field of low intensity modifies the evoked epileptiform seizure activity in rats. Cumulative effect of the electromagnetic field persisted over the course of 6 months. It was suggested that inhibition of the increased motor activity under exposure to electromagnetic field is caused by the involvement of dopaminergic brain systems and development of the resonance effects in cortico-subcortical brain structures under the influence of modulated electromagnetic fields.

[Changes in brain memory functions as affected by a constant magnetic field]. / Izmeneniia mnesticheskikh funktsii mozga pod deistviem postoiannogo magnitnogo polia.

Effects of CMF on memory processes in adult volunteers (non-sleep us hypnotic condition) has been studied at laboratory and clinical conditions. The results point out that CMF changes the interhemispheric relations and result in memory malfunction. The malfunction of memory activity in volunteers after action of CMF was influenced by two factors: magnetic field position under different brain areas and functional status of volunteers: awake or hypnotic.

[Dynamics of the formation, reproduction and recognition of trace conditioned reflexes to positive and negative stimuli]. / Dinamika formirovaniia, reproduktsii i osoznaniia sledovykh uslovnykh refleksov na polozhitel'nye i otritsatel'nye razdrazhiteli.

The dynamics of formation, reproduction, and recognition of trace conditioned reflexes to positive and differentiation stimuli was studied on subjects of 15-17 years old. Formation and reproduction of such reflexes was found to occur under a close interaction of both levels of the higher nervous activity--recognized and unrecognized levels. Recognized reactions prevailed on unrecognized ones in cases of involvement of active attention. On the basis of this fact, the formation and reproduction of trace conditioned reflexes to positive stimuli has been supposed to occur with an active participation of the left hemisphere. The right hemisphere apparently plays a leading role in formation and reproduction of trace conditioned reflexes to differention stimuli to which the attention of the subjects was not fixed.
