Study objectives are dedicated to brief synthesized establishment of diagnostics general standard, management and therapy of major depressive disorders (MDD) in clinical medicine to provide education in medical practice.
Study methods are based on short-term, medium-term and long-term educational programs in 24 Russian and Ukraine cities, which were based on original educational programs under the direction of World Psychiatric Association (WPA) and International Committee For Prevention and Treatment of Depression (PTD). There, about 1450 doctors of different occupations were acquainted with the detection, management and treatment of MDD. The Russian version of WPA/PTD programs was created. The program of education included 4 modules. The Core module included an overview of the epidemiology, impact, concepts and classification, and etiology of depressive disorders as well as their recognition, diagnosis, and management in the primary care setting. The second module focused on depressive disorders in physical illness and covered those major illnesses for which is reasonable evidence for an association with depressive disorders. The third module included the development of the depressive disorders in older persons. The forth module included training physicians in mental health skills. 39 theme improvements for 858 primary care setting physicians within the framework of faculty training program of physicians’ development were the part of other programs of physicians’ occupations.
Results. A number of highlights were included in the general algorithm of the educational programs. The creation of optimum «physician-depressive patient» contact demands a number of new skills to establish effective communication. These skills involve training of meeting of depressive patient and physician, the ability to follow a certain communication style; identify emotional, cognitive, psychomotor and nonverbal patterns of behavior. Besides that, the education included adherence to therapy and therapeutic alliance during the period of informed agreement. There was an education of fluent grasp of medicaments, which are the first choice in therapy. Integration of this knowledge is done during the periods of repeated interactive discussions of antidepressants’ effectiveness in depression therapy which is based on three-phased MDD therapy model. The process of working out the depressive patients’ management was based on systematization and diagnostic of depression disorders (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, or International Classification of Diseases, Revision 10); detailed discussions of manifestation and thorough depression symptomatology; management approaches in depression disorders, different in manifestation.
Conclusion. The basis of physicians' education was the idea that depressive disorder in holistic approach can't be considered as an independent psychiatric disease in its mild and moderate forms of manifestation. Depression, along with coronary artery disease, cerebrovascular diseases, diabetes, osteoporosis, obesity and fatness should be considered by clinical medicine within one cluster of noninfectious multifactorial chronic diseases.
ORIGINAL PAPERS
The purpose of work was the assessment of influence of a palliative resection of a liver with application of cryodestruction and without cryodestruction application on the remote results of treatment of the patients who have been repeatedly operated for alveococcosis.
The analysis of surgical treatment of 14 patients operated repeatedly for alveococcosis of a liver is carried out. Patients were operated in the complicated stage of a disease in the presence of germination of a parasite in caval and/or portal gate of organ. Primary interventions were various – a diagnostic laparotomy, a cytoreduction and a marsupialization of a parasite, a liver resection. All patient at repetition intervention executed palliative resections of a liver. Resections were carried out by a clinic technique with imposing the ginglymoid of ligatures on remaining tissue of a liver at distance of 2–3 cm from the deleted parasitic knot taking into account a segmentary structure of organ. At all patients on "dangerous zones" (a zones of gate of a liver, a hepatoduodenal ligament) plates of parasitic fabric of various sizes from 1 2 cm to 2 4 cm were left. At 10 patients they were exposed to cryodestruction. The exposition in one point made from 1 to 2 minutes at a temperature –196 С. Postoperatively, patients received a dose of 10 mg/kg albendazole.
Development of hepatic insufficiency after palliative resections of a liver is noted in one case. Lethal outcomes weren't.
All patients for convenience of the analysis were divided into two groups: group of patients without application of cryotechnologies (n = 4) and group of the patients operated with application of cryodestruction (n = 10). Efficiency of palliative resections estimated on a median of survival of patients. Calculation of survival carried out Kaplan–Meier's method. The survival median in groups made 12 and 17 years respectively.
When comparing survival of patients by Gehan's test with Yates's correction distinction of survival in two selections are statistically significant (z = 2,94; p < 0,005).
Among patients repeatedly operated for alveococcosis when involving in parasitic process of gate of a liver, lack of possibility of prosthetics of vascular structures and developments of a compensatory hypertrophy of not struck departments of body the palliative resection allows to achieve survival of 50% of patients more than 16,8 years.
Cryodestruction is the effective and safe method, allowing to increase survival of patients after a p alliative resection of a liver, through the destruction left in the area of the liver gate parasitic tissue sections.
Oxidative stress is one of the pathogenetic components of many diseases during which generation of reactive oxigen species increases and the capacity of the antioxidant protection system diminishes. In the research of the last decades special attention has been given to adipose tissue, production of adipokines by it and their role in development of immunoresistance associated with formation of the metabolic syndrome and diabetes.
Search for methods of therapeutic correction of adipokine secretion disorders, their influence on metabolism of separate cells and the organism on the whole as well as development of new approaches to correction of disorders in cell sensitivity to insulin are extremely topical nowadays. Systematization and consolidation of accumulated data allow to determine the strategies of further research more accurately; as a result, we have attempted to summarize and analyze the accumulated data on the role of adipose tissue in oxidative stress development.
On the basis of literature data and the results of the personal investigations, the role of adipose tissue in forming oxidative stress in diabetes has been analyzed in the article. Brief description of adipose tissue was given as a secretory organ regulating metabolic processes in adipocytes and influencing functions of various organs and systems of the body. Mechanisms of disorder in insulin secretion as well as development of insulin sesistance in type I diabetes were described along with the contribution of lipolysis in adipose tissue to these processes.
Comuunity-acquired pneumonias in aged patients is the significant epidemiology problem for the public health of almost all the countries. Even more important the problem of microbiological monitoring and epidemiology surveillance for the S. pneumoniae strains as one of the ubiquitous pathogens causing as the community-acquired pneumonias as well the other infections of respiratory tract, what defines their different epidemiological meaning.
Multilocus sequence typing is the perspective method of molecular epidemiological surveillance allowing to define the epidemiologically dangerous clones of the ubiquitous microorganisms as Streptococcus pneumomiae. The aim of our research was to conduct the multilocus sequence typing of pneumococci strains isolated in patients with community acquired pneumonias, bronchitis in aged patients.
Materials and methods. There were taken 14 strains of S. pneumoniae, isolated in patients with community-acquired pneumonias (seven of them were multiresistant), eight strains were isolated from patients with the chronical onstructive lung diseases and four strains from carriers. Multilocus sequence typing was conduected according to method to M.C. Enright and B.G. Spratt (1998).
Results. The strains, isolated in all populations were the related isolates of the species S. pneumoniae, the most of them had the unique genotype defining the sequence type for every strain. There were 6 strains of Taiwan 19F-14 genotype from 14 strains isolated in aged patients with community-acquired pneumonia. Among strains isolated from carriers there were prevailing the strai of R6 genotype.
Conclusion. Multilocus sequence typing allows to identify the new genotypes and to prognose the appearing of epidemiologically dangerous strains with new peculiarities.
The relationships of risk factors with hypertension in workers of coal enterprises were studied. Based on the identified predictors developed risk prediction scale of this disease in miners.
Surveyed 792 employees of the mine “Polosukhinskaya”. Along with a complete clinical, anthropometric and laboratory testing, conducted settlement criterion relative risk of developing hypertension.
The most important factors determining the increased risk of disease in workers of coal enterprises were: increased body weight, age, waist circumference, and the index “waist/hip”, elevated levels of total cholesterol, triglycerides, low density lipoprotein cholesterol, atherogenic index. These signs and have the greatest prognostic factors that increase the risk of developing the disease.
Aim of research. We have evaluated the abilities of new original paramagnetic contrast agent Mn-DCTA (0,5 mol solution of Manganese(II) complex with trans-1,2-diaminocyclohexane-N,N,N',N'-tetraacetate, registered trade mark Cyclomang) for contrast-enhanced imaging of brain meningeomas in dogs.
Material and methods. Twelve animals were included, all with brain tumors reveald during out-patient veterinary examinations. In ten of twelve the diagnosis was verified later by pathomorphologic study. The cerebral MRI has been carred out as set of axial, sagittal and coronal slices as thin as three to five mm, covering all the volume of brain.
The scanning parameters in T1-weighted spin-ech mode were as follows: TR = 400–500 ms, TE = 15–20 ms, the dose of injected paramagnetic was standardised as 1 mmol per 10 kg of body weight. For quantitative analysis the index of enhancement was calculated.
Results. In all cases the sure enhancement with clear visualization of cerebral tumor was obtained due to highly intensive uptake of Mn-DCTA to the tumor tissue. When evaluated quantitatively the uptake of Mn-DCTA to the tumor gave the index of enhancement in T1-weighted spin-echo mode as high as IE = 1,72 ± 0,18 for the central parts of tumor and IE = 2,08 ± 0,23 for the peripheral ones, where as in control animals it was far below these values. Intravenous injection of Mn-DCTA to dogs with cerebral tumors did not induce any detectable pathologic or even physiologic effects.
Conclusion. Henceforth we conclude the Mn-DCTA provides highly available methodologically simple imaging of cerebral meningeomas and can be thought out as promising paramagnetic agent for clinical magnetic resonance imaging in humans.
The results from the selective validation research into the association between genetic polymorphisms and the frequency of cytogenetic abnormalities on a large independent sample are analyzed. These polymorphisms have been identified previously during own microarray studies. It has been shown an association with the frequency of dicentric and ring chromosomes induced by radiation exposure. The study was conducted among Siberian Group of Chemical Enterprises healthy employees (n = 573) exposed to professional irradiation in a dose range of 40–400 mSv. We have found that 5 SNP are confirmed to be associated with the frequency of dicentric and ring: INSR rs1051690 – insulin receptor gene; WRNrs2725349 – Werner syndrome gene, RecQ helicase-like; VCAM1 rs1041163 – vascular cell adhesion molecule 1 gene; PCTP rs2114443 – phosphatidylcholine transfer protein gene; TNKS rs7462102 – tankyrase gene; TRF1-interacting ankyrin-related ADP-ribose polymerase. IGF1 rs2373721 – insulin-like growth factor 1 gene has not confirmed to be associated with the frequency of dicentric and ring chromosomes.
Purpose. To evaluate lymphokinetic activity of the dihydroquercetin and arabinogalactan composition.
Material and methods. The investigation was carried out on male Wistar rats. Lymphokinetic activity was determined by the rate of lymph outflow through the puncture of cisterna chili after intragastricall administration of the dihydroquercetin and arabinogalactan composition with ratio 1 : 5 (50 mg/kg + 250 mg/kg).
Results. It was established that lymphokinetic activity of the dihydroquercetin and arabinogalactan composition with ratio 1 : 5 (50 mg/kg + 250 mg/kg) exceeds activity of it´s components.
Currently, diabetes ranks third in relation to medical and social significance after cardiovascular diseases and cancer and is the leading cause of blindness; it greatly increases the risk of myocardial infarction, coronary heart disease, nephropathy and hypertension in patients with this disorder; therefore clinical and experimental studies aimed at investigation of diabetes emergence and development mechanisms are urgent.
The aim of the study was to investigate the status of oxidative modification of proteins and glutathionedependent antioxidant defense system in adipocytes of rats with alloxan diabetes under conditions of oxidative stress.
Material and methods. Development of type 1 diabetes was induced in rats by alloxan administration (90 mg/kg of body mass). Adipocytes were obtained from epididymal adipose tissue of rats. The level of carbonyl derivatives of proteins, oxidized tryptophan, bityrosine, general, reduced, oxygenated and protein-bound glutathione, as well as glutathione peroxidase activity in adipocytes of rats was determined.
Results. In adipocytes of rats with alloxan diabetes, concentration of carbonyl derivatives of proteins, bityrosine and oxidized tryptophan increased on the background of redox-potential of glutathione system and glutathione peroxidase activity decrease.
Conclusion. The obtained data indicate the activation of free-radical oxidation of proteins and reduction of antioxidant defense under conditions of oxidative stress in the adipose tissue of rats with alloxan diabetes; this process plays an important role in pathogenesis of diabetes and its complications development.
REVIEW AND LECTURES
The basic information on the classification, structure, induction and degradation, functions of the protein family – metallothionein (MT), including CNS in health and disease are presented in this review. It was found that four major isoforms of metallothionein perform different biological roles, are localized in dif- ferent tissues. Induction of MT is a universal reaction to the impact of a variety of stress factors. In recent years, understanding of the role of metallothioneins in metal homeostasis in the tissues in normal and pathological conditions have changed significantly. Notes polyfunctionality metallothioneins (transport of metal ions, maintaining redox reactions, tread, signal, modulated and regulatory functions) and their im- pact on basic cellular functions such as proliferation, differentiation, programmed cell death. Further- more, a special role is shown MT in the pathogenesis of cardiovascular, neurodegenerative and neoplastic disorders.
Currently, these molecules are increasingly considered as potential targets for therapy of a wide range of diseases and the development of targeted approaches to the regulation of expression of MT – one of the promising areas of pharmacology and toxicology. Stressed the safety of metallothioneins as therapeutic agents.
High-grade malignant gliomas (WHO grade G III–IV) account for more than 50% of all primary brain tumors. Despite aggressive treatment, survival rates are still very low with a median reported survival of no more than 1.5 years.
Radiation therapy is an integral part of the combined treatment, but often does not influence lethally on resistant tumor cells. Thereby, in recent decades there has been an active search for novel approaches to the treatment of malignant gliomas (chemotherapeutic drugs, biological modifiers, local hyperthermia). Experimental data showed that the effect of high temperatures has both a direct damaging effect on tumor cells and a sensitizing effect. Significant advantages are achieved when the complex treatment of different malignant tumorsincludes local hyperthermia. However data on the treatment of patients with primary and recurrent gliomas G III–IV using local hyperthermia are scarce.
The literature review is given in the article provides an overview of the existing treatment methods for brain tumors.
