The relevance of Takotsubo cardiomyopathy as a stress-induced disease
Статья научная
Takotsubo cardiomyopathy, or Takotsubo syndrome, can be quite rare found, but however the frequency of diagnosing with this disease among patients of cardiology departments is constantly growing. On the one hand, this may be due to improved diagnostics of this pathology, and on the other hand, to an increasing frequency of mental disorders in the human population and the spread of other risk factors, including drug-induced variants. The pathogenesis of the development of Takotsubo cardiomyopathy is associated with an increase in the level of catecholamines, which may be the result of a reactive sympathetic enhancement in response to external factors or be the result of taking antidepressants that can produce a similar effect. Although the diagnostics of this pathology has made significant progress, but however there is still no consensus on the strategy of treatment. This is due to the lack of large-scale randomized prospective studies that could justify one or another therapeutic approach. Basically, the efforts of medical doctors are aimed at maintaining cardiac activity, eliminating the trigger of the disease and at treating complications.

The low efficacy of ongoing conventional therapy and a significant decrease in the quality of life in patients with reconstructive plastic surgery (RPO) on the pelvic organs (PO) due to tubal-peritoneal infertility (TPI) and chronic nonspecific salpingo-oophoritis (CNSO) requires searching for new, promising methods of non-drug treatment, in particular, taking into account the regional characteristics of the Republic of North Ossetia-Alania and its natural resources. One of the main ways to increase the efficacy and intensify the treatment of this category of patients is the use of natural factors, namely, sulfide waters of the local Redant-4 deposit, which have a number of anti-inflammatory effects. Purpose of the study is to assess the role of non-drug technologies using magnetic infrared-laser therapy and balneological factors of the local deposit in the rehabilitation of the reproductive function in patients undergoing reconstructive plastic surgery due to TPI and CNSO. Material and methods. 235 women with impaired reproductive function, who underwent laparoscopic reconstructive plastic surgery on the pelvic organs (RPO on PO) due to tubal-peritoneal infertility (TPI) and CNSO, whose average age was 28 + 7 years, were examined. 2 groups were formed by the method of blind sampling: the main group consisted of 139 women with RPO on the pelvic organs due to TPI and CNSO, who, along with conventional therapy, received magnetic IR-laser therapy and had hydrogen sulfide baths; the comparison group included 96 women with RPO on PO due to TPI and CNSO, whose treatment was carried out by conventional methods of drug therapy. The conventional treatment included along with antibiotic therapy the use of ecological adaptogens (aloe, apilac), immune modulators (polyoxidonium), vitamin therapy (vitamin E 100 mg / day for 3 months and B vitamins), drugs to eliminate disorders in the intestinal and vaginal flora (antifungal agents: fluconazole, tergynan, acylact for 7-14 days). The patients of the studied groups were observed before their treatment and 1-12 months after the treatment. All patients underwent a clinical and functional examination. Statistical processing of the material was carried out using the package Statistica for Windows. Results. A control examination of patients of both groups showed a more pronounced positive effect on the course of a number of clinical symptoms in the postoperative period in the main group of patients who received magnetic IR laser therapy and had sulfide baths of the North Ossetian deposit in the complex of therapy. As a result of the physiotherapy treatment, the pain syndrome was eliminated in 107 of 139 patients (77%) who complained of pain before their treatment. A decrease in pelvic pain after the course of treatment was noted in 46 patients (33%). It should be noted that in the majority of patients 94 (68%), who received sulfide balneotherapy, a decrease in the formation of repeated adhesions of the pelvis was revealed during the procedures, the effectiveness of the regression of the adhesive process was found throughout the observation. It was detected that against the background of the proposed non-drug technology in the rehabilitation treatment of patients with RPO on PO due to TPI and CNSO, a significant increase in the effectiveness of treatment of this pathology (89%), improvement in the quality of life of patients as well as restoration of fertility has been achieved. Conclusions. The use of the method of sulfide balneotherapy in patients with RPO on PO due to TPI and CNSO allows shortening the duration of their next treatment and achieving the maintenance of positive dynamics and duration of regression of the adhesive process of the pelvis.

To study about the relation between oxygen delivery and hemodynamics during cardiopulmonary bypass
Статья научная
The study put forth the relation between oxygen delivery and hemodynamics during cardiopulmonary bypass. The study was performed on 26 patients of either sex have age > 10 years and who underwent elective open-heart surgery from June 2017 - May 2018 in Sri Ramachandra Medical College & Research Institute. The patients with valvular heart diseases associated with other cardiac lesions like Intra cardiac shunts (ASD, VSD etc.) and Coronary artery disease (CABG) are excluded in the study. It examined the relationships among VO2, hemodynamics & DO2 during clinical perfusion, namely throughout moderately hypothermic CPB using a non-pulsatile roller pump while managing the alpha-stat acid-base with adults. The results revealed a linear relationship between VO2 and DO2, demonstrating that higher levels of delivery can perfuse and collect additional vascular beds throughout the CPB. Under bodily tissue perfusion, higher deliveries are advised to be avoided. The oxygen demand decreases by 7% for every 1OC decline in patient temperature.

Trigeminy electrocardiogram spectral characteristics study
Статья научная
This paper presents the results of a study in which the method of ECG decomposition in the time domain (DMTD) was applied, followed by a spectral analysis. A digital signal with trigeminy of the first lead of a standard electrocardiograph was processed. Using digital filtering in time domain, the electrocardiogram (ECG) was cleared of noise, what results the reduction of spurious components by 10-20%. To represent and classify the frequency characteristics throughout the entire processed cardiac signal, the QRS complexes were removed, P and T waves were left unchanged. Due to considerable influence on the spectral analysis sharp peaks of the ECG signal with small characteristic times of the leading and trailing edges, the obtained result differs considerably from the sum of the harmonic components of the smooth part of the signal. The spectral processing reveals peaks at multiple frequencies, 1.6 Hz, 3.2 Hz, 4.7 Hz, corresponding to a smooth function of P and T waves before the appearance of extra systoles. Based on the obtained data, the frequencies corresponding to the peaks of the cardiogram with a stable sinus rhythm were identified. The acquired data represent regular harmonics, which allow adequate quantitative ECG analysis.

Today, among the urgent tasks facing the pharmaceutical science of the Republic of Uzbekistan is the study of introduced medicinal plants. Of the promising plants Erva woolly - Aerva lanata Juss of the amaranth family (Amaranthaceae) deserves special attention. A perennial or biennial herbaceous plant grows in many countries of Africa, Saudi Arabia, India, Indonesia, etc. For the first time, Aerva lanata Juss. was introduced on the territory of the former USSR by the Transcaucasian zonal experimental station VILR (Kobuletti) in the mid-70s, then in Ukraine, Uzbekistan and Kazakhstan. Aerva lanata is a dioecious plant. The flowers of A. lanata are nectariferous. Pollination of Erva woolly occurs under the influence of gravity inside the flower, wind, insects and rainwater. Erva woolly with more than one pollination and seed dispersal mode is able to invade a variety of habitats with different environmental conditions and grow as widespread weeds. Among other Aerva species, A. lanata cultivar has a wide range of pharmacological activities such as sedative, antiulcer, antiasthma, antidiarrheal, antioxidant, antihyperglycemic, antimalarial, hypolipidemic and other activities. It is used as a diuretic, for acute kidney damage, as well as for ulcerative wounds, rheumatism. Given the availability of the raw material base necessary to meet the possible growth in consumer demand and its widespread use in traditional and scientific medicine to create effective, low-toxic drugs intended for the prevention and treatment of diseases of the urinary system, Aerva lanata Juss L. was chosen as the object of research. An important stage in the standardization of the final product is the quality control of the technological process and the raw materials entering the production to obtain the finished product. Particular attention is paid to the method of quantitative determination of one of the active substances or groups of biologically active substances that affect the therapeutic effect of finished pharmaceutical products. It is known that the quantitative determination of the active substance is carried out by its extraction from plant materials. In this regard, the problem arises - finding the optimal conditions for the process of extracting the active substance. In view of this, it becomes necessary to conduct research to determine the optimal conditions for the extraction process. The objective of the research: the use of the mathematical planning method of the experiment for the complete extraction of flavonoids from the herb Aerva lanata. To achieve this objective, the following tasks were defined: - selection of the mathematical planning method of the experiment; - selection of method for quantitative determination of flavonoids amount; - statistical analysis of the obtained results. Optimization of the process of extracting the amount of flavonoids from the herb of Aerva lanata, which is predominant in its raw materials, was carried out using the method of mathematical planning of experiments by Box and Wilson. The optimization problem was reduced to determining the values of technological parameters that ensure the maximum yield of total flavonoids from the plant. As an optimization parameter, Y was taken - the content of the sum of flavonoids in the extract, in % of its content in the raw material. Conclusion. This article presents the results of modeling and optimization of the process of obtaining the sum of flavonoids from the herb Aerva lanata Juss. L. A comprehensive quantitative assessment of the influence of three experimental factors (alcohol concentration, hydromodulus and extraction time) on the yield of the total flavonoids was carried out using the method of mathematical planning of the Box-Wilson experiment. The objective was achieved by building a mathematical model based on the first order regression equation: Y=1.20+0.185X1+0.091X2+0.111X3 The adequacy of this process is shown, a mathematical model and parametric identification of this model are presented. As a result of the statistical analysis of the obtained data, the following optimal conditions for the process of extracting the amount of flavonoids from the herb of Aerva lanata were revealed in the quantitative analysis of raw materials: alcohol concentration - 50%; hydromodule - 1:60; extraction time - 30 min. The maximum yield of the sum of flavonoids was 1.52% by weight of dry raw materials. The resulting mathematical model of the extraction process will allow further optimization of the extraction of compounds of natural origin, taking into account the quantitative influence of each factor.
