ABSTRACT
A clinical-neurological, psychological, biochemical and electromyographic study of 40 operated and 40 non-operated patients with chronic low back pain syndrome was conducted before and after treatment. The authors used various modes of administration of xydifonum, a chelate from the group of bisphosphonates, including electrophoretic, peroral and administration in the form of ointment, administered in turn with heparin one to improve the antiplatelet effect, using photopheresis the with the help of the state-of-the art photomatrix LED equipment. The application of Ca2+-modulating properties of xydifonum demonstrate its universality in achieving of analgesic, muscle-relaxing, anxiolytic and antidepressant effects thus allowing to exclude polypragmasy. This is a main difference between this drug and other medications with limited effects. Based on the results obtained, the authors propose a scheme of development of chronic low back pain.

A new combined photoultrasonic technique is suggested for the treatment of infectious injuries. The experiments were implemented on 70 male chinchilla rabbits (7 groups). The dynamics and nature of injuries' healing were analyzed by clinical pathomorphological and histochemical data as well as by biopsy samplings and capillaroscopy of injuries' edges. The experimental results of animals' models demonstrated a high efficiency of the combined photoultrasonic treatment as applicable to the above injuries.

An algorithm for calculating the spatial distribution of radiation intensity from type-transparency matrix therapeutical apparatuses based on superbright light-emitting diodes is considered. The method developed takes into account the geometric and topological features of both radiation sources themselves and irradiated surfaces. The algorithm proposed is important in solving the problems of dosimetry of light therapeutical apparatuses already used in medical practice and those under design.

A procedure is proposed to search for acupuncture points and channels (APC) by space-sensitive recording of optical radiation diffusely reflected by surface (dermal and hypodermal) tissues of the body. For this purpose, the body surface is probed by low-intensity infrared radiation from a laser or noncoherent (light-emitting diodes) source by using a fiber-optic multichannel sensor. It is shown that it is most advisable to apply sources at wavelengths of 840-850 and 1260-1300 nm.

The paper details three of the technologies used in the treatment of infected wounds (ultrasound, photodynamic, photomatrix ones) with emphasis on the authors' developed combined photo ultrasound technique. It presents the results of clinical application of these technologies, discusses its capacities, limitations, and prospects alone and in combination. The high efficiency of combined exposure--the photo ultrasound method--is shown.

The paper deals with the development of devices for visualization on intravascular formations by using multifiber optical catheters, describes a scheme for a pilot testing unit based on periodical pulse-acting Nd:YAG laser that operates at the second harmonics (lambda = 532 nm). Analyzes errors while processing the return signal received by intravascular objects, proposes a statistical model which describes the received signal, which permits the development a of block diagram for an optimized device for initial processing of signals.

The molding of laser energy by spherical microlens fiber tips applied to laser angioplasty has been experimentally calculated and investigated. The Monte-Carlo method has been proposed to simplify a calculation procedure. This has reduced the necessary amount of test light rays (250 versus 2100 in the former studies). A simplified calculation model (bicentric) is given, which replaces the Monte-Carlo method in many practical cases. The calculation data are in a good agreement with experimental findings.

The paper underlines the necessity of taking into account the relationship of the basic characteristics of multifiber optical catheters, such as the number, position, and diameters of some fibers, to the informational potentials of diagnostic and imaging systems of the basis of the catheters. The relationship is established by applying discretization theorems. The main points are illustrated by an example of practical angioplastic calculation.

With laser angioplasty the hemoglobin absorbtion effect on the demolishing of the pathological objects was taken into consideration. It was stated that this effect is high for argon lasers (lambda = 0.488 = 0.514 microns) and insignificant for solid state laser (lambda = 1.064 microns). In this respect growth of laser capacity practically is not increasing the efficiency of the pathological objects destruction at a distance not more than 1 mm from the out-put of the light-guide.

A possibility to improve endoscopic diagnosis by laser illumination is considered. The fact that the image contrast of the pathologic tissue on the normal tissues background may be increased markedly compared to wideband incoherent illumination is shown. The possible increasing of the contrast by laser illumination of the blue-violet band (0.44 mkm) is evaluated. Advantages of laser light compared to incoherent sources with passive filters are discussed. The calculated results are compared to that of the model experiment.
