Antibiotic resistance of microbial community of the lake Baikal ecosystem in the area of Listvyanka, Slyudyanka and Baikalsk

The article presents the results of study of antibiotic resistance of bacteria isolated from the lake Baikal ecosystem. It was revealed that in the littoral zone of the lake Baikal (area of Listvyanka, Baikalsk, Slyudyanka) under the anthropogenic impact there are strains of microorganisms resistant to a wide range of antibiotics. Strains resistant to all antibiotics are 1 % of the isolated bacterial strains; strains sensitive to all antibiotics are 6 %; strains isolated from the drill samples of bottom sediments are 80 %. This phenomenon can be considered as an indicator of anthropogenic influence

Significance of EMG and ENMG in the Diagnosis and Treatment of Degenerative-Dystrophic Diseases of the Spine (Literature Review)

The article presents the review of domestic and foreign literature on the use of neurophysiological diagnostic methods – electroneuromyography (ENMG) and electromyography (EMG) in degenerative-dystrophic diseases of the spine. The ENMG method is of great importance for theoretical neurology, obtaining new data on the structural and functional organization of the central and peripheral nervous system in the process of individual development. Electromyography as a diagnostic method studies the electrical activity of the peripheral apparatus of the nervous system. With these methods we directly evaluate both voluntary bioelectric activity of muscles at rest and during their activation (EMG), and caused by stimulation (ENMG). Most authors believe that modifications of stimulation electromyography are objective diagnostic methods that allow to assess the functional state of the peripheral nervous system. Interesting is the fact that changes in EMG and ENMG parameters for osteochondrosis of the spine are recorded even in the absence of external manifestations of the disease. At the same time, for patients with myofascial syndrome in lumbar osteochondrosis, a bilateral decrease in the direct and reflex excitability of motoneurons is characteristic, a slowing down of the pulse along the arc of the H-reflex on the side of the pain and a two-sided local acceleration of the pulse on the distal part of the efferent part of the H-reflex arc from the popliteal pits to soleus muscle. Noteworthy is the fact that the pathological process in the nervous tissue according to ENMG in patients with osteochondrosis of the spine with unilateral radicular syndromes is bilateral. The work of our clinic has shown that diagnostic electroneuromyography can be considered as a medical procedure – electropuncture, according to its results, tactics of both surgical and conservative treatment can be determined. Data of EMG and EMG, carried out after the end of any of the listed types of treatment, serve as an objective control of their effectiveness

Comparative analysis of electroneuromyographic values in patients with scapulohumeral pain syndrome of degenerative genesis and cervical osteochondrosis

The aim of the research was to study electrophysiological values in patients with blade-humerus pain syndrome at cervical osteochondrosis and posttraumatic shoulder injuries. We managed 71 patients: 33 patients with cervical osteochondrosis and brachialgia getting conservative treatment in the neurosurgical unit of Irkutsk Scientific Center of Surgery and Traumatology (group 1) and 38 patients with injuries of shoulder joint capsules and ligaments getting treatment in the unit of traumatology and orthopedics (group 2). Comparison of electroneuromyographic values in patients of both groups showed unidirectional changes in the values and accentuated decrease in electroneuromyographic parameters on both affected and unaffected extremities. In both cases median nerve was affected most. We registered the decrease in conduction velocity of motor fibers of intact nerves in patients of both groups. Lack of clinical signs of lesion of these nerves can be indicative of functional changes in nerve conduction which reflect generalized reaction on the lesion of certain nerve stems

DIAGNOSTICS OF OSTEOPOROSIS IN PATIENTS WITH DEFORMING DISEASES OF LOWER EXTREMITIES’ LARGE JOINTS AND SPINE

With the purpose of studying of bone tissue state at the degenerative dystrophic changes of musculoskeletal system, of the 3—4th degree densitometry with use of ultrasonic densitometer Sunlight Omnisens was carried out in preoperative period, in patients in the age from 50 to 72 years. These patients had. diskogenic lumbosacral radiculitis, one-sided. L—St radiculoneuritis, one-sided, degenerative coxarthrosis of the III degree and one-sided deforming gonarthrosis of the III degree. As the results in examined, groups of patients high percent of osteoporosis and ostheopenia was revealed. It was registered that intensity of osteoporotic changes on diseased. and. healthy extremities was different and. to a greater extent they showed, up on a diseased, extremity. This data confirmed, opportunities of ultrasonic densitometer Sunlight Omnisens to diagnose of ostheoporosis at earlier stages

ADVANTAGES OF ROD EXTERNAL FIXATION AT DIAPHYSEAL FRACTURES OF FOREARM BONES ACCORDING TO THE DATA OF RHEOVASOGRAPHY

The authors present the result of the research of peripheral blood flow of upper extremity in patients with diaphyseal fractures of forearm bones at transosseous osteosynthesis by external fixation devices of different set. Significant difference between rheographic indices and the set of external fixation device: greater effectiveness of transosseous osteosynthesis by rod external fixation devices with saving of moves in joints interfacing with injured segments was determined

DYNAMICS OF PERIPHERAL BLOOD CIRCULATION IN TREATMENT OF RADIAL BONE FRACTURES WITH THE METHOD OF PEROSSEOUS OSTEOSYNTHESIS

To study the parameters of peripheral blood circulation of upper extremity in patients with fractures of radial bone at perosseous osteosynthesis we studied the group of patients with fractures externally fixed by apparatus with pin arrangement and the group of patients treated by apparatus of rod arrangement. Rheovasographic examination of upper extremities was performed before the surgery, the day after it, on the 7th, 14th and 21st day after the surgery. In all patients during preoperational period we revealed disturbances of blood circulation in distal parts of upper extremities of angiospastic type giving evidence of sympathicotonia. Having analized the results of clinical and rheovasographic researches in established terms of observation we were able to mark gradual improvement of arterial and venous blood flow in forearm in examined groups. In the group with rod fixation positive dynamics occurred 5-7 days earlier than in the group with pin fixation. Original method was applied, consisting in rod fixation of apparatus of external fixation. Evaluation of clinical parameters marks good results in 97 % of cases. In early postoperative period improvement of rheovasographic parameters has been marked, which says about increased blood perfusion in tissues and about normalized vessel tone

Relationship of Cerebral Hemodynamics and Cerebral Bioelectrical Activity in Patients with Cervical Osteochondrosis

Introduction. Osteochondrosis of the cervical spine is a very common disease that causes a significant decrease in the quality of life of patients. In the case of pronounced changes in the cervical spine with osteochondrosis, there is a violation of blood circulation in the cerebral cortex, which leads to pronounced clinical symptoms.The aim of this study was to identify a correlation between bioelectrical activity and cerebral hemodynamics in patients with osteochondrosis of the cervical spine.Materials and methods. The examination involved 25 patients of the neurosurgical department who received conservative treatment for exacerbation of osteochondrosis of the cervical spine, and 25 volunteers without a history of diseases of the spine and joints. The cerebral bioelectrical activity and blood flow indicators were recorded in the pool of the common carotid and vertebral arteries.Results. In the main group and the clinical comparison group, the rheographic index and the peripheral vascular resistance index were studied, which characterize both the volume pulse blood filling of the vascular bed and the tone of small and medium caliber arteries. At the same time, the EEG rhythm indices were analyzed: а-, в-, S-, and в-waves. An analysis of the intersystem interaction of bloodflow indices and the biopotentials of the cortical rhythm of the brain in the main group showed a mismatch in the intra-system connections, which corresponds to the period of the general stress of the body. An analysis of the correlation between the indicators of electroencephalography and rheoencepha-lography in the control group revealed a stable system of correlation between the indicators, showing intersystem and intrasystem consistency and reflecting a high level of reserve capacity of the body and the state of steady adaptation to adverse factors.Conclusion. The use of simultaneous recording of cerebral hemodynamics and brain biopotentials in patients with osteochondrosis of the cervical spine will allow clinicians to correctly assess the functional state of the central nervous system and to prescribe adequate treatment in a timely manner
