research of a cerebral hemodynamics by a method reoentsefalografii

Registration tetrapoljarnoj REG was spent after 5-minute acclimatisation of examinees in position sitting on four abductions at fronto-mastoidalnoj (FM) and oktsipito-mastoidalnoj (OM) localisations of electrodes, on the right and at the left accordingly.

In the given situation we recognised that peak and time parametres of curve REG, reflecting pulsovye fluctuations of electrical resistance of a brain to a current of high frequency passed through it, are indicators of an assessment of intensity krovenapolnenija investigated ranges of a brain. Thus FM - abductions characterise total krovenapolnenie the big hemispheres, and OM - a hemodynamics state mainly in pool of backboned arteries, vaskuljarizujushchih a prolate and back brain (H.H.Jarullin, 1983). Registration was spent on a diagnostic complex "Valenta" (Open Company "Company Neo", St.-Petersburg) at speed of 50 mm/with and it is selective about reografa-polyanalyzer "РЕАН-ПОЛИ-6/12" use (NPKF «Physician MTD», Taganrog). In total on 4 abductions it has been registered 340 reoentsefalogramm. Analysis received REG included calculation of average peak, time and high-speed indicators, and
Also of some indexes, according to M.A.Ronkina and L.B.Ivanov's work (1997).

1. Reografichesky index RI (c.u.) - an assessment volume pulsovogo krovenapolnenija cerebral pots:

RI = А/U,

And - voltage of a systolic wave; U - size kalibrovochnogo a signal (0,1 Ohm at speed of locomotion of a tape of 50 mm/c).

2. The quotient of asymmetry KA (%) - characterises asymmetry krovenapolnenija:

Ab - voltage of the rheogram on the party where RI it is more, Am - voltage of the rheogram on the party where RI it is less.

3. Speed fast krovenapolnenija V6 (the Ohm/c) - reflects a state of a tone of arteries of distributive phylum:

А1 - Voltage of the maximum steepness anakroty; α1 - time of fast filling of pots.

4. Speed slow krovenapolnenija Vm (the Ohm/c) - characterises a tone of arteries of resistive phylum:

А2 - The maximum voltage of a systolic wave; α2 - time of slow filling of pots.

5. An indicator of venous outflow IN (%):

‰ - average speed of decreasing of the rheogram on last quarter of a cardial cycle; Vb - average speed of increase venous components (the attitude of voltage of a maximum venous components by time of its achievement).
