The purpose of the investigation was to study the nootropic effects of rhythmic transcranial magnetic stimulation (rTMS) using low-intensity magnetic field with the induction rate of 45 mT, base frequency of 50 Hz, modulation frequency of 10 Hz in combination with standard medical and psychological therapy in the rehabilitation of patients with post-stroke cognitive impairment (PSCI). Materials and methods. The rehabilitation outcomes in 98 patients with PSCI syndrome were studied. The patients were subdivided into 2 groups: 53 patients of the control group were treated with the standard nootropic medications and neuropsychological procedures; 45 patients of the main group were additionally treated with rTMS by the low-intensive running pulsed magnetic field of 10 Hz modulation frequency. The dynamics of the score increase according to Rivermid, Karnovsky, Roshina, MMSE, mRS, HDRS, SF-36 scales were analyzed. Conclusion. Application of rTMS with low-intensive running pulsed magnetic field of 10 Hz modulation frequency in combination with a standard program of cognitive rehabilitation contributes to a significant improvement in the recovery of mental calculation function in ischemic stroke patients, as well as normalization in mood swings in the patients who had suffered a hemorrhagic stroke and post-stroke depression. This variant of rTMS can be safely used in patients with PSCI syndrome in the early recovery period, 3 weeks after the onset of stroke.

Microscope slides, dipped 24 h into cultures of oral bacterium Streptococcus mutans, accumulated up to 66% more bacterial polysaccharide on the side of the slides facing north. Reversal of the magnetic field by 180° caused similar reversal of the preferential accumulation. The process of preferential accumulation becomes saturated at 1.7 gauss [Formula: see text].
