NLS-semiotics of pulmonary gangrene differed
by significant diversification of a picture due to spreading of
purulent-destructive process to the whole lung with involvement of pleura and,
as a result, a combination of various NLS-symptoms. Analysis of NLS-image was
carried out taking into account the whole clinical picture. After taking as a
basis of classification the leading symptom we nominally singled out three
NLS-variants of gangrene. At the first variant (11 patients) in a lung against
the background of massive inflammatory infiltration we detected a major cavity
of destruction with mainly liquid content, NLS-picture was analogous to
gangrenous abscess with insufficient spontaneous drainage. Walls of a cavity
were not visualized, it was limited by lung parenchyma, in certain areas the
line between them was indistinct.
At the second variant (7 patients) in the
picture prevailed total thickening (accompanied by increasing of chromogeneity)
of a lobe or the whole lung with presence of multiple roundish achromogenic
areas due to lesser air cavities of destruction. In 3 patients, apart from air
cavities, there were hyperchromogenic fluid-containing cavities of decay (6
point), in one patient they prevailed in the structure of gangrenous lung. In 8
of 18 patients with first two variants of gangrene a pleural empyema with the
typical picture appeared.
The third variant of lung gangrene (4
patients) had a course with development of pyopneumothorax, when a massive
pleural fluid with heterogeneous suspension and achromogenic inclusions of air
was the leading echo-symptom. Gangrenous changes in a pulmonary tissue were
characterized by one of above mentioned variants: a major cavity with purulent
content of multiple lesser nidi of destruction.
Thus, NLS-research of thorax is an
informative, radiologically safe method of purulent-destructive lungs and pleura
diseases diagnostics, allowing to not only acquire additional information, but
to carry out primary examination and dynamic monitoring. NLS-semiotics of
pathological changes in a lung is diverse and depends, first of all, on focal or
diffuse character of lung affection. Analysis of NLS-picture makes possible to
define a character and severity a purulent-destructive process in a lung (acute
purulent or gangrenous abscess, abscess forming pneumonia, gangrene), its
spreading to pleural cavity (empyema, pyopneumothorax). The common factor, which
determines NLS-picture of purulent cavity at abscess and abscess forming
pneumonia, is a condition of its spontaneous drainage, which is evaluated by
quantity and character of distribution of achromogenic air areas in a cavity.
The main symptom of pleural empyema is a presence of a thick chromogeneous
suspension in pleural fluid; at pyopneumothorax achromogenic air areas appear.
NLS-semiotics of gangrene is quite diverse due to the greatest severity of
destructive changes and is formed by focal and diffuse changes in a lung,
although its clinical course may be characterized by prevalence of one of these
variants.

Possibilities of NLS-study methods in examination of certain skin diseases
Wide spread of skin diseases dictates a necessity in
early and maximum accurate diagnostics, because severe forms of skin diseases
decrease greatly quality of life of a patient and his family, promote
development of a psychosomatic disorders. Visual evaluation of symptoms and
severity of a disease often has subjective nature.
From histological point of view skin consists of two
layers: epidermis and derma which are closely connected. On histological
cross-cuts of skin a line between epidermis and derma looks uneven due to
presence of many dermal papillae divided by outgrowths of epidermis. Epidermis
consists of several layers: basal, spinous, granular and horny. In epidermis of
palms and feet, between granular and horny layers there is additional layer –
stratum lucidum. Sometimes the aggregate of basal, spinous and granular layers
is called a malpighian layer.
Derma is a connective basis of skin, where
perspiratory and sebaceous glands, blood and lymph vessels, nerves and smooth
muscles are located. There are papillary and reticular layers of derma.
Papillary layer, located under epidermis, and a part of reticular layer
conditionally form upper derma; layer of derma located at the level of
pilosebaceous unit is indicated as middle derma; the underlying layer containing
perspiratory glands, bordering subcutaneous fat, is called a deep
derma.
Blood vessels of skin form two anatomic plexuses: a
deep one, located next to subcutaneous fat, and a superficial one, located in
sub-papillary layer. They consist of microcirculatory bloodstream vessels:
arterioles, venules and capillary tubes.
Total thickness of skin without subcutaneous fat
varies from bits of a millimeter to 4 mm.
Exiting systems for NLS-diagnostics (“Metatron”-4019)
are equipped with high-frequency linear generators (1.4 GHz) allowing to
visualize the most superficial structures, in particular skin. However to
evaluate condition of ultrafine structures of skin such frequency is not enough
sometimes. That is why dermatologists started to use special devices with
sensors of 40 GHz operating frequency, which allow to see the finest structures
of skin layers down to the level of large carbohydrate molecules and peptides.
But at the same time due to significant cost of such equipment if becomes
unaffordable for wide application in the majority of clinics. Taking into
account a need in evaluation of regional lymph nodes and tumors of soft tissues,
apparently the optimal decision is to use devices for non-linear diagnostics
equipped with non-linear sensors of 4.9 GHz operating frequency
(“Metatron”-4025, the IPP, Russia).
“Metatron”-4025 system has axial resolution of 30 µm.
Application of this device allows to study epidermis on cellular and
sub-cellular levels.
Nowadays objectives and limits of three-dimensional
NLS-ultramicroscanning research in dermatology have become very
broad.

Auxiliary treatment of covid-19 patients with oxygen concentrator
Working Principle
The Oxygen Concentrator adopts the advanced (PSA) pressure swing adsorption air separation technology, which is based on the difference of adsorbability of adsorbents (zeolite molecular sieve) to nitrogen and oxygen in air, and the different adsorption characteristics of the sorbent under different pressure to achieve the separation of oxygen and nitrogen.
There are two pressure swing adsorption towers filled with molecular sieve in the oxygen making machine. When the air enters the adsorption tower A, which contains the adsorbents, the nitrogen adsorption capacity is strong and the oxygen is not adsorbed. When the air is pressurized, the nitrogen in the air can be adsorbed, the unabsorbed oxygen is collected into a gas collecting chamber at the lower end of the adsorption tower. After the set intake cycle is completed, the adsorption tower A ends the intake to produce oxygen and enters the nitrogen removal process, while the other adsorption tower B enters the nitrogen removal process simultaneously, and uses the oxygen separated from the adsorption tower B to reverse blow the adsorption tower A, the nitrogen adsorbed by molecular sieve in adsorption tower A is blown back into the ambient air, and the nitrogen can be adsorbed again at the next pressurization to make oxygen. The whole process is dynamic and cyclic, and molecular sieve is not consumed. In this way, high concentration of oxygen can be obtained at the outlet of the adsorption tower. PSA (pressure swing adsorption) technology is called because of the characteristic of adsorbents which change with the pressure, so the adsorbents can be adsorbed alternately.
Scope of application
