INTRODUCTION
Metastasis remains a major problem in cancer. That
is, in fact, migration of the cancer cells through the
circulatory and lymphatic systems which gives rise to
new tumor formation in various tissues [1]. Violation of
the genetic control is due to lack of the tissue regulation,
and cells come out of the immune system control. When
tissue homeostasis happens a proliferation occurs due to
that T-lymphocytes cannot reach an infected cell from
the bloodstream through the endothelial cell membrane
to kill cancers.
In essence the oncogene concept reduces to an asser-
tion that the source of malignant growth is enclosed in a
normal cell, in its genome, while the initiated impulse
comes from outside. Activation of eigen-genes (proto-
oncogenes) under influence of chemical, physical, ra-
diological and biological factors is considered to be a
reason for the transformation. Tissue regulation with the
restoration of disturbed genetic control has no genetic
character and could be a plausible alternative.
In this paper a solution for strengthening the re-
sponse of the immune system problem based on the
following physical processes using UHF radiation:
1. Charge removal from the region of dielectrics with
different values of dielectric constant and a dielectric
waveguide.
2. Penetration depth of the UHF radiation into a bio-
logical tissue compared to other radiation frequencies.
3. Water as a polar molecule occupies ∼ 70% of the
blood composition.
4. Relaxation time of the interstitial fluid.
5. Water in free and bound states in a biological tis-
sue, interference of UHF vibrations when committing
changes in the molecular states.
6. Levels of UHF absorption power to allocate a lim-
ited region in a biological sample as it moves in the
standing wave of the microwave-resonator.
7. Closed and open UHF-resonators and parabolic re-
flector UHF-antennas.
8. Of a particular interest are the processes taking
place between water molecules in various states of mo-
lecular groups making up the biological structures.
1. MATERIALS AND METHODS
The most promising method for solving the stated
problem is usage of UHF-radiation in the frequency
range corresponding to the area of water dispersion.
Water condition specifics should be reflected in dynam-
ics of its dielectric properties, which are a valuable
source of information on the relationship of body fluids
in vessels. An UHF-resonator allows to record even
small structural changes in biological components be-
tween free and bound water [2 - 4]. The purpose of this
work is to develop an UHF-resonator for a living bio-
logical object for a mechanism of cleaning of the vessel
with a dilute electrolyte.
Distribution of fields in a half-period cavity resona-
tor with H011 type of oscillations and based on a rec-
tangular waveguide with a continuous energy exchange
between E- and H-fields is shown in Fig. 1.

size 278×256×45 mm; 2 – shorting plunger; 3 – hinge
connection; 4 – magnetic lines of force; 5 – electric
lines of force. The parameters of the cavity resonator
are as follows: f=0.5…1.1 GHz; λ0=37.5 cm;
λcr=36.8 cm; fcr=815 MHz
2. CONTROL OF THE PROCESS
OF ENERGY ABSORPTION
IN THE UHF CAVITY
Introduction of a metallic screen [5] with a gap and a
microwave absorber – energy (Fig. 2) into the cavity
leads to a decrease in its resonant frequency and its Q-
factor. These physical processes influence choice of the
gap width when injecting the UHF-energy into a biolog-
ical object to determine the state of water (an analogy of
blood with its components) in free or in bound state.
The screen of the object (pos. 6, 10) serving as a ra-
diation reflector is made of a copper foil with holes
having 4 mm diameter and a thickness significantly
greater that the skin effect. A clearance (see Fig. 3) is

required to inject UHF radiation and electrodes into the
living biological entity.

cavity with a screen. 1 – screen; 2 – E-field of a stand-
ing wave in the cavity; 3 – E-field in the cavity with a
continuous screen; 4 – E-field in the screen gap, d is the
gap width in the screen. Distribution of E-field in the
cavity with clearance of d = 20 mm in the screen is
measured by moving a disturbance body of a thin metal
disk (see Fig. 4)
According to Figs. 3 and 4 area with the highest lev-
el of absorption of the electric field is located in the
center of the cavity. Higher vibration modes are not
present, α is a transmission coefficient of UHF into
absorber (water) through the gap d>0, and it is equal to
1
21
Q
QQ −
=α , wherein Q1 is a Q-factor of the cavity
with screen, absorber and gap in the screen; Q2 is a Q-
factor of the cavity of the same geometry with zero
clearance. Value of α is 30% for the gap of d = 20 mm
(see Fig. 4). α can be reduced by lowering the size of
the test object.
Fig. 4. Dependence of the taken signal level
on the position of the perturbing body in the cavity
The Q value remains large and changes weakly when
a large perturbing body (screen) is installed horizontally
in the UHF cavity. This will allow to inject an electrode
horizontally into the screen for electrophoresis in the E
⊥ H – fields configuration. The screen with openings
reflects the UHF wave, but a part of it flows into the
absorber with a large value of the dielectric constant.
These processes have opposite directions, that deter-
mines the value of the Q-factor of the cavity. Difference
in the Q-factor for a cylinder with and without water is
due to the power loss in its end walls. A screen with
openings of 4 mm diameter does not transmit UHF
energy into the cylinder, as losses in the side walls of
the hole in a solid and screens are almost identical.
Difference in the Q-factor for a screened cylinder with
and without water is due to the power loss in its end
walls.
3. SHIELDED OBJECT
IN THE UHF CAVITY
Principal features of the screen function in the cavity
can be considered using a model of oscillation circuit
with lumped parameters (Fig. 5).

of the capacitor with a water absorber;

4. SENSITIVITY OF THE CAVITY
If a local leak occurs in the wall of the cylinder,
through which water seeps out and is converted into
steam accumulated in the volume of the resonator, addi-
tional losses with decreasing Q-factor are created. Fig-
ure 6a shows dependence of Q-factor of the cavity with
a water-filled cylinder in the presence of a leak. The
graph shows that the reduction in the Q-factor of the
cavity over time is not linear. First, the Q-factor de-
creases sharply with further relaxation of its reduction
speed. Sensitivity of the cavity depends on its Q-factor.
The cavity is more sensitive to the conditions of humidi-
ty in its entirety. After elimination of the local leakage
and the cavity volume ventilation the Q-factor recovers
from 980 to 2000. For a gap in the screen with d =
5 mm (Fig. 6,b) an internal reflection of the UHF wave
from water absorber with a large value of the dielectric
constant is recorded.

Interference occurs between the reflected waves and
the screen of the open portion of the water absorber
through a gap in the screen, which causes a local in-
crease in the cavity Q-factor.
Based on Q-factor value change of the cavity the
resonance method will identify gaps in the molecular
bonds toxins membranes of capillary walls and sub-
strates embolus intoxication of blood.

5. PROCESS OF CLEANING VESSELS AS
A WAY TO DETOXIFY THE CAPILLARIES
The process of cleaning the walls of blood vessels
occurs due to knocking of additional ions out from their
surface by accelerated ions of the electrolyte in the
applied electric field in the creation of the Lorentz force
FL= q[VxB] in E⊥B − geometry fields (Fig. 7). The
centripetal force Fc= MV2/R equals to the Lorentz force
for the motion of the ion in a circle.

in the electrolyte volume at various values of the mag-
netic induction. 1 – electrodes in the electrolyte;
2 – radii of the ions in E⊥B – fields in the XOY plane
at magnetic induction in the range of Bmin-Bmax;
3 – inner surface of the vessel

wherein B, θ, V, ε, M are magnetic induction, charge,
speed, energy, and the ion mass, respectively. The value
of εkin should be sufficient to break the covalent intera-
tomic bonds, and Rcycl > Rvessel. According to the reac-
tion of electrolysis of water-activated sodium chloride
strong solution NaCl+n⋅Н2О → NaOH·(n–1)Н2О+½
Cl2+½H2 chlorine, caustic and hydrogen get re-
leased. Design of the vessel provides gas output from its
scope. Chlorine is 2.5 times heavier than the air, and 2.3
volume of chlorine gets dissolved in a unit volume of
water. Sodium hydroxide remains in solution. Water has
the largest capacity of dissociating with the value of the
dielectric constant ( 81=ε ).
Current ionic conductivity is determined by the ion
mobility Eb /ν= , where ν is the ion velocity acquired
in an electric field dUE /−= , with U – the voltage on
the electrodes, and d – the distance between them. At
movement of the ions in a viscous medium they are
affected by the internal friction force, which is subject
to the Stokes' law as πηρν6=frE . In order to over-
come the friction force it is required that qEE fr −= .
Ion mobility is written as rqb πη6/= , where η
− solution viscosity, r – radius of a positively charged
ion. The absolute value of β=v at E = 1. Velocity
of positively charged ion is bEE

. The
magnitude of the ion velocity in the electric field of the
electrolyte determines the radius of its movement to-
wards the vessel wall according to M
qB
R ν
= . The
conductivity of the electrolyte depends on the ions con-
centration and their mobility.
With increasing of magnetic induction (Bmax) the ra-
dius of the ions movement is reduced, and the ions do
not reach the walls of the vessel, which leads to a nega-
tive result for its purification (see Fig. 7).
For cleaning of the entire inner surface of the wall it
is necessary to optimize magnitude of the magnetic
induction and to rotate the vessel in the transverse direc-
tion w.r.t. the electric field E, i.e. around the OX axis.
6. EXPERIMENT
For the experiment as shown in Fig. 8 an aqueous
sodium chloride solution with a sufficiently large dilu-
tion is applied.
After dissolution of the salt in water contains only
anions and cations, and the solution remains electrically
neutral. The electric field of the ion mobility of the
electrolyte increases, reduced charge factor blocking
ions of hydrogen-bonded water molecules.

CONCLUSIONS
It opens up the prospect of developing a new tech-
nology based on the combined action of a biological
object of constant electromagnetic fields and radio fre-
quency resonance diagnostics in the decimeter wave-
length range. Microwave radiation is supposed to be
introduced into the object under study (a living organ-
ism) through a limited clearance in the protective screen
to determine the level of intoxication and the state of the
walls of blood vessels. A wide range of measurement
capabilities of the resonator Q-factor enable explore the
biological object in different states and monitor relative
changes in its structure.
