What we are studying
is
the question
of
a
biological
entity having
a
magnetic
field.
First
of
all
as
for
the strength
of
the magnetic
field,
we
remember that
close
to
an
iron magnet
the strength
of
the magnetic
field
is
about
100 oersted.
The magnetic
field
of
the earth
is
0.5 oersted.
The
intensity
of
the magnetic field generated
by living things
is
10-e
oersted.
Changes
in
the magnetic
field can affect
a series
of
functional
processes
of
the living entity.
It
can have
a
clear effect
on humans
as
well.
However,
with the human magnetic field
so weak,
it
is very difficult
to be detected
or
to be affected
by another.
—
Are you following this
line
of
research?
—
The entire world
is conducting
research.
Several major cities
in
the
Soviet Union
such
as Moscow,
HAERKEFU
[phonetic],
TUOMUSIKE
[phonetic],
and
DUBUNUO
[phonetic]
have
all
begun
to conduct
this
kind
of
research
and
how
biological magnetic
fields
assist
in clearing up important details
in the
biological
processes.
At
the same
time
it
is providing new possibilities
in
medical diagnosis.
—
What
can
be learned from
a doctor analyzing
a person's magnetic field?
Also,
how are these magnetic
fields generally produced.
Normally,
the magnetic field only occurs when
a magnetic charge
is
in
motion.
The different magnetic signals
in our bodies are caused by the ion
current which occurs simultaneously with nerve impulses.
As for magnetic
diagnosis,
well,
at
the present
time the magnetic signal
tapes
can be used
in
studying the heart,
brain and muscle signals.
Our laboratory has already
cooperated with
the Soviet Union Academy
of Medicine All-Soviet Heart Treatment
Science Center in
a joint
study of
the question
of
the weak magnetic
field
of
the heart.
One
of our tasks
is to accurately locate
the focus
of
various
disorders.
This will assist
in reasonable and effective treatment.
—
Do you mean say that you cannot use
the extremely simple traditional
methods such
as EKG
to locate
the focus
of
disorders.
—
Currently new methods are required,
because
the traditional methods
can only determine the general location
of
the disorder
in
the heart,
and when
modern medicine
is conducting targeted treatment,
it requires more accuracy.
When traditional methods are recording
the heart
current,
it receives
interference from different currents from other tissue which
can cause serious
image distortion.
However,
it
is
a different story when using magnetic fields.
The magnetic field
is like the body
is completely transparent.
It does not
generate any interference or distortion.
Therefore,
methods of
recording
the
magnetic fields formed by the heart determine specific seats
of
disease with
an
error of no more than one millimeter.
Prior
to these methods,
however,
in order
to record
this type
of magnetic field
it was necessary
to insert
an electrode
into the heart.
—
What
is
the difference between recording
the magnetic
field of
the
brain
and recording
the magnetic field
of
the heart?

The major difficulty
in studying
the brain
is
that
the brain magnetic
signals
are
at
a very
low level
(to weak).
The intensity
of
recorded brain
magnetic
field intensity
is only
10-8
oersted.
This
is only equal
to one
percent
of
the intensity of
the magnetic field
of
the heart.
Furthermore,
it
is extremely difficult
to differentiate
the extremely weak brain magnetic
signals from interference several
tens
of
thousands
of
times
as strong.
We are
presently doing research on
a type
of new method called search
and capture
of
brain magnetic
fields.
It
is
the use
of
sound,
flashes
of
light
and weak
electric current
to stimulate magnetic reaction
from the brain.
An even more
important
task
is
the study
of
structure of
different regions
of
the brain
and
their operational
sequence.
—
Is there interest
in applied medicine toward
studying
the magnetic
fields
of
the brain?
—
Of
course
there
is
interest.
For basically
the same
reasons,
the chart
of
the brain's magnetic field,
just
as
the chart
of
the heart's magnetic field
can precisely locate
the seat
of
a disorder
in
the brain,
and
can
do
it much
more accurately
than
traditional methods
of using EEGs
.
Under many conditions,
such
as neurosurgery,
a chart
of
the brain magnetic
field
is extremely
important
.
— Does
this mean that
the recording
of
brain and heart magnetic fields
will be adopted by clinical doctors?
—
Undoubtedly
it will
be used
in various large hospitals.
However,
many
complex problems must be resolved before
they can
be put
to actual
use,
especially mass production
of
super conductor quantum interference
(magnetic
field)
detectors and magnetic field intensity measuring devices.
From the
surface,
this kind
of
precision instrument will basically be
a super conductor
loop,
with one or two high
level
connecting apparatus
(called JIAOZEFUSUONOFU
contacts)
[phonetic]
.
They will
all need
to be immersed
in
liquid helium.
They would have
the ability to detect
the weakest
of magnetic fields,
as weak
as
10" 12
oersted.
Therefore,
it can actually be
truly called
an
instrument
with super-sensitive abilities.
It will be have super sensitivity,
and obtain
successful
results
in the study of human super-sensitive ability.
This brilliant creation will
soon enter the realm of medical common
treatment.
I am afraid none
of
us
can find suitable words
to praise
this
type
of modern medical
new technology.
The following was extracted
from my notes on talks during my visit with
lab researcher and physicist
and mathematician Assistant Doctor MIUXING
[phonetic]
.
"We are beginning
to study the always existing,
more accurately the rarely
changing,
human body magnetic fields.
We have completely entered another
realm,
we have entered
the exhaustive study
of
several micromechanisms
of
control
of
body temperature.
This
is not
a shift
in
interest.
We were

searching
for
the electric power source
for
the body's magnetic
fields
and
discovered
that
the electrical
power source
is
on
the shin.
Thus,
we should
analyze
its nature,
and
this unavoidably
led
to
the
study
of
the processes
of
body temperature control
and heat
transfer.
The skin
is
a very complex
biological
living machine.
It
s
a primary object
of
our
long
term research.
—
Both
skin
and heat control
have been studied
for dozens
of
years.
Almost everything has been researched.
Do you
think that
all
the subtleties
and minor details have been discovered?
—
However,
when we start
to take
a close
look,
and conscientiously
measure and use
the philosophy
of
physics
to evaluate and
analyze,
we will
necessarily discover several
significant
and major details.
At
times we may
even change
the way we view the basic nature
of
some things.
Thus,
we want
to
make clear what
is
the cause that generates
the change
in
the static potential
on
the surface
of
the human
body.
—
Excuse me for interrupting,
but
I would
like
to know where the
electrical
charge comes
from.
Where does
the body's magnetic
field
first
appear?
—
The human body permanent static electric field has been known about
for
a long time and has been measured on many occasions.
However,
there are
a
number of different interpretations
of
this phenomenon.
There are even people
who believe
that
there are electrets
- permanently magnetized electrovalent
elements on our
skin.
Actually,
because
of
the life
in our bodies,
it
can
cause
the surface skin
to have
a weak potential
of
0.05 volts,
and
the maximum
potential may be
as high
as
ten volts.
For example,
rubbing
the back of
the
hand briskly several
times
can generate this result
(friction generated
electricity)
.
—
Can
the use of
this
type
of method
to generate electricity generate
much more
than
10 volts?
-
Normally not.
The electrical field voltage
at
some spots may be
higher,
but sparks will
occur at
the high voltages,
and
this will
restrict
the
increase
of
the potential.
It
is not important
to know where the static
electrical
field on our bodies
is generated.
The important
thing
is what
causes
the static electric field and how
is
it quickly
lost.
In
this process,
the primary role
is played by the subcutaneous
layer
of
the skin which
is only
40 microns
thick.
The subcutaneous layer
is also
an excellent insulating
layer.
After the surface generates electricity from fiction,
it becomes
a
unique capacitor.
The subcutaneous layer
is
a dielectric.
Furthermore,
the
lower skin has relatively good conductivity.
The changes
in potential
are
conducted throughout
the body to create
a magnetic
field.
If
the subcutaneous
layer generates free electric charge,
then
there
is
a
"current".
When
a
capacitor discharges,
the static electric field
is
lost.
Naturally,
this
is
a
macroscopic view,
actually
the so-called "current"
is extremely weak,
no more
than
a
few hundred millionths of
an ampere.
Therefore,
the change in the

potential
on
the external
layer are also extremely
slow,
and
it
take several
minutes
to several
tens
of
minutes
to reduce
it
by half.
In
the beginning,
we carefully studied
the nature
of
the subcutaneous
layer.
We measured
the resistance
to be between
10 -9
and
10" 12
ohrns
per square
centimeter.
In order
for the human body
to adapt
to changes
in
the outside
temperature,
it has two primary control
systems.
One
of
these
is
the sweat
gland systems with which we are
familiar.
When
it
is
hot,
after
the
hypothalamus receives heat signals,
it
immediately orders the sweat glands
to
secrete perspiration
through
the skin.
The perspiration continuously
evaporates
and carries
the heat
away.
The other system
is
the cold prevention
system.
When
the weather
is very
cold,
the hypothalamus
issues orders
to speed
up blood circulation
and
intensify biochemical
reaction processes
to ensure
the
energy
supply.
Finally,
it
even uses shivering methods
to alter
the heating
mechanism.
In
addition,
the skin
also has small
systems which function
independently
in some areas.
At 0.5 mm below
the surface
of. the skin,
there
is
a network of
capillaries.
The dilation
or contraction
of
these capillaries
is
a primary factor which directly functions
to regulate
the body
temperature.
It
is responsible
for one-third
of
the heat dissipation.
—
Is
a great deal
of water evaporated through our skin?
— An
adult will perspire 50 grams over
a
24 hour period without realizing
it.
During heavy perspiration,
a liter or more can be lost
every hour.
The
area
automatic temperature regulating systems
can only function within
a small
range of outside temperatures.
For example
in
a room with
a temperature
of
around 20 degrees Celsius,
its operations can reflect
a number of
important
signals such
as the blood supply,
blood vessel
state,
the degree
of
activity
in
a
series
of biochemical
reaction processes.
Furthermore
it not
only reflects
the area epidermis situation,
but
it can also reflect
the situation with
certain
internal
organs.
Thus,
we need only measure the intensity
of
perspiration
of
one piece of
skin and we can determine the change
in
the
electric field
in
the area
as well
as
the blood supply situation
in
the area.
This
is
the overall
situation.
At
the same time this
research
can also show
changes
in interesting biological mechanisms and numerical
contrasting
relationships.
— Are there remote sensing methods?
—
When
an electrical
field exists,
it
is possible
to detect
this
at
a
certain distance.
The faster the electrical
field disappears,
the stronger
the
conductivity
of
the surface layer
of
the
skin.
The more charge
lost,
then
the
more rapidly
the water
is transported.
Naturally,
it
is only with electrical
methods
that
it
is possible to measure the thermosensitivity
of
the skin.
It
appears that
the skin thermosensitivity
is very high,
about
0.1
milliwatt/square centimeter.
That
is
to
say,
the skin
can
feel
the heat from
a
burning match at
a distance
of one meter.
