3. Biomedical applications
Biological objects are known for their high sensitivity to weak external fields. The evidence
that electromagnetic fields can have “non-thermal” biological effects is now overwhelming.
When the production of heat shock proteins is triggered electromagnetically it needs 100
million times less energy than when triggered by heat [20]. Low-frequency weak magnetic
fields may lead to the resonant change of the rate of biochemical reactions although the impact
energy is by ten orders of magnitude less than
k
B
T
where
k
B
is the Boltzmann constant and
T
is the temperature of the medium [21].
The therapeutic ability of the low intensity electromagnetic radiations is actively discussed
[22]. The low-power millimeter wave irradiation and magnetic-resonance therapy are used in
practical medicine already, which differ significantly from the drug treatment by the fact that
they do not clog organism with the undesirable chemical compounds, i.e. xenobiotics. In this
chapter we discuss the biomedical application of vacuum-plasma technologies.
3.1. Activating and therapeutic properties of water processed in GDP
To understand the above extreme sensitivity of living objects, investigations in influences of
weak fields on water appear to be essential. Indeed, water plays a major role in biological
processes. A man consumes about 2 l of drinking water a day. Water is the main component
of human, animal, plant and generally every living being body. A new-born child body
contains 97% of water, decreasing to 70-75% with aging. In particular, human brain consists
of about 85% of water.
So, we performed experiments with water, crop seeds and baking yeast
S. cerevisiae
. The crop
seeds and yeast were processed directly in GDP. Also, the untreated crop seeds and yeast were
poured with the water processed in GDP. In all cases practically the same biotrophic effects
were observed. Namely, the seed sprouts showed the growth in 3-4 times higher than the
control samples. Both the processed yeast and the unprocessed one that immersed in the
processed (by GDP) water showed greater metabolic activity compared to the control samples.
The obtained results allow suggesting that the discovered phenomena can be used for direct
correction of pathological states. Therefore we processed water and physiological solution.
The samples were exposed to low-energy ion irradiation in GDP of residual gases. The ion
energy depends on the voltage in the plasma generator. The latter was kept at 1.2 keV while
the current in the plasma generator was maintained at 70 mA. The temperature in the chamber
was controlled during the irradiation process and did not exceed 298 K (25° C). The irradiation
time was 60 minutes.
In test experiments, volunteers with different diseases either drunk the processed water or
they were injected intravenously with the similarly processed physiological solution. The
course of treatment included 3-5 sessions of 0.5 l physiological solution transfusion. The
preliminary results appeared to be very promising. We were most interested in the therapeutic
treatment of the global inflammatory processes such as cardio-vascular diseases and pancre‐
