Nicasius Ellebodius És Az „Otium Litterarum”.
Authors: Orbán Áron
Published: November 2020

A tanulmány Nicasius Ellebodius életének utolsó, pozsonyi időszakát (1571–1577) dolgozza fel, bepillantást nyújtva a ﬂamand humanista izgalmas személyiségébe és sokoldalú tevékenységébe. Ellebodius, aki a francia-ﬂandriai Casselben született 1535-ben, és Leuvenben, Rómában, illetve Padovában tanult, a XVI. századi Európa egyik legjobb klasszikus ﬁlológusává vált. Radéczy István püspök és helytartó patronáltjaként élete utolsó időszakát Pozsonyban töltötte. Számos klasszikus görög – főleg aristotelési – mű redakcióján, latin parafrázisán dolgozott. Míg nagyobb ﬁlológiai teljesítményeit már értékelte a nemzetközi szakirodalom, élete és személye háttérbe szorult a kutatásban. Fennmaradt levelezése viszont – melynek nagyobb része a pozsonyi időszakból való – kiváló alkalmat nyújt arra, hogy a művek mögé pillantva rálássunk személyiségére és tevékenységére. A tanulmány különösen arra a kérdésre keresi a választ, mennyire tudta megvalósítani Pozsonyban az olyannyira áhított otium litterarumot, és milyen egzisztenciális problémákkal kellett szembenéznie Magyarországon.

The study revisits Nicasius Ellebodius’s life and character as can be outlined from the sources of his Bratislavan (Pozsony) period. Ellebodius, who was born in Cassel in French Flanders in 1535 and studied in Leuven, Rome and Padua, became one of sixteenth-century Europe’s best classical philologists. Patronised by Bishop István Radéczy, he spent the last period of his life basically in Bratislava. He worked on editions or paraphrases of several – primarily Aristotelian – classical Greek works. While his major philological achievements have already been assessed by international research, scholars have not delved deep into his biography. His surviving correspondence – the majority of which belongs to his Bratislavan period – provides an opportunity to look behind the works and gain insight into his activities and personality. The study focuses on the problem how far he could realise the otium litterarum that he yearned so much and what challenges he had to face in his everyday life in Hungary.

Authors: Taboada-Verona Carlos , Murillo-Ramos Leidys
Published: November 2020

We provide species lists and geographical occurrence records of the beetle family Passalidae for three subregions of the department of Sucre, northern Colombia. The sampling localities are lowland environments with typical tropical dry forest vegetation. We selected 15 sampling sites and examined decomposing trunks. We record seven species, four genera, and two tribes of Passalidae. The most abundant species were Passalus punctiger Lepeletier & Serville, 1825, P. interstitialis Eschscholtz, 1829, and P. interruptus (Linnaeus, 1758). We also provide new records for Passalus punctatostriatus Percheron, 1835, Paxillus leachi MacLeay, 1819, and Popilius marginatus (Percheron, 1835) in the department of Sucre. Veturius aspina Kuwert, 1898 was present only in the localities with well-preserved forests. Finally, the species number recorded in this study is low compared to other inventories in Neotropical regions.

Authors:   Azerbaijan Medical University, Baku, Aliyeva Gunay Ilham
Published: November 2020

The objective: to study the significance of the presence of hypothyroidism syndrome as a risk factor for the development of autonomic neuropathy (AN). Materials and methods. The study involved 77 women, of whom 31 had hypothyroidism syndrome, and 46 had euthyroid thyroid pathology. The age of patients with hypothyroidism syndrome ranged from 24 to 57 years and averaged 42.4±9.20 years, mean age patients of the euthyroid pathology group of the thyroid gland was equal to 40.0±12.22 years (age interval 20–63 years). Patients underwent an ultrasound examination of the thyroid gland, fasting glycemia levels, A1c, TSH, T4s, T3s, blood creatinine levels, and GFR were calculated using CKD-EPI on line equations. In addition, antithyroglobulin and antithyroperoxidase levels were determined. To diagnose autonomic neuropathy, a Valsalva test and a deep breathing test were used. Statistical analysis was performed using the standard computer program Microsoft Excel. Results. The state of autonomous innervation was normal in 71.0% of the examined hypothyroidism group and in 97.8% of the euthyroidism group. AN was absent both in hypothyroidism syndrome (0.0%) and in euthyroid thyroid pathology (0.0%). Moreover, the “borderline state” of autonomic innervation was observed in 29.0% of the examined groups of hypothyroidism syndrome and only 2.2% of the examined groups of thyroid euthyroid pathology (p=0.0019). The chance of finding parasympathetic disorders in the hypothyroidism group was 0.409, and in the group of euthyroid thyroid pathology was 0.022. Conclusions. Thus, in the presence of hypothyroidism, the chances of finding autonomic disorders were 18.409 times higher than those for euthyroid thyroid pathology, which requires appropriate correction when planning comprehensive treatment tactics. Key words: autonomic neuropathy, hypothyroidism syndrome, euthyroid pathology of the thyroid gland.

The problem of premature rupture of membranes (PROM) is unfortunately still relevant in modern obstetrics and perinatology, especially in preterm pregnancy, and leads to 20% of all cases of perinatal loss. Among the possible causes, a lot of attention has recently been paid to disorders of connective tissue structure of genetic origin. The article provides an overview of current medical literature on the causes and diagnosis of PROM. Preliminary own data on the positive effect of the advanced algorithm for detecting undifferentiated connective tissue dysplasia (UCTD) on obstetric and perinatal outcomes are also given. The objective: to clarify the causes of PROM, the role of the severity of connective tissue dysplasia to predict risk factors for preterm birth, especially when combined in pregnant women with anemia. Materials and methods. A total of 60 pregnant women with IDF were examined. During the survey, laboratory and instrumental methods were used. Results. Quality of life in women with NDTT had an inverse mean relationship between the patients’ well-being and the number of PST phenotypic manifestations (r = 0.653; p> 94%). In addition, a high constitutionally determined level of personal anxiety was established. Quality of life depends on the number and severity of phenotypic abnormalities, ie the more signs of connective tissue dysplasia (joint hypermobility, scoliosis, nephroptosis, increased bleeding, myopia, pronounced varicose veins, etc.), the lower this indicator. As pregnancy progressed, worsening of health and decrease in quality of life in patients with NDST was observed. Conclusion. The advanced algorithm has demonstrated the positive effects in pregnant women with undifferentiated connective tissue dysplasia on obstetric and perinatal delivery, and the findings suggest that it is practiced in health care. Key words: premature rupture of membranes, preterm pregnancy, undifferentiated connective tissue dysplasia.

The objective: peculiarities of pregnancy in women with common worm infestations in Baku. Materials and methods. During the period from 2015 to 2017, 152 women with common worm infestations were examined, in the gestation period from 16 to 40 weeks in the age group from 18 to 38 years. Depending on the nature of the infestation, 2 main groups were formed: the 1st main group included 84 women who had monoinvasia of helminths, and the 2nd main group included 68 women who had mixed helminth infestation. The control group consisted of 42 women who were pregnant without helminthiasis. All women were examined at 16–22, 23–29, 30–36 and 37–40 weeks of pregnancy. Helminthosis diagnostics was performed by detecting helminth eggs in faecal smears, pinworm eggs in scraping from perianal folds, and visual detection of helminth eggs or pinworms in faeces and vomit. Results. Common symptoms of early toxicosis are nausea, hypersalivation, and vomiting. A rare form of morning sickness treat dermatosis pregnant women, pregnant bronchial asthma, tetany, acute yellow atrophy of the liver, osteomalacia. Symptoms of toxicosis were evaluated in 152 pregnant women. The main symptoms of early toxicosis–nausea, hypersalivation and vomiting–were more common in pregnant women with helminthiasis than in women of the control group. In women with helminthiasis, a symptom complex similar to the manifestations of early toxicosis may persist throughout pregnancy, despite ongoing toxicosis therapy. Since persistent nausea and vomiting can be etiologically caused by helminthic-protozoic intoxication, the frequency of nausea and vomiting in different groups in the second and third trimesters was compared. In the second half of pregnancy, women with complaints of nausea and vomiting were present in all study groups, but they were more common in pregnant women with helminthiasis than in women in the control group. Conclusions. The data obtained on the more frequent manifestation of early toxicosis in pregnant women with helminthiasis and its demonstrated resistance throughout pregnancy prove that helminth infestations negatively affect the course of pregnancy. Key words: helminth-protozoal invasion, placental insufficiency, pregnancy.
Practical aspects of bacterial vaginosis: relevance, diagnosis and comprehensive treatment
Authors:   Shupyk National Medical Academy of Postgraduate Education, Kiev, Mehedko V.V.
Published: November 2020

Bacterial vaginosis (BV) is significantly widespread in the population: its detection rate in women with inflammatory diseases of the urinary system is 35%, among pregnant women – 10-30%, among patients with sexually transmitted infection – 20-60%. The presence of BV leads to pregnancy complications, after gynecological surgery and the development of relapses of the disease. To achieve a full therapeutic effect, it is necessary not only to conduct antimicrobial therapy, but also to restore the vaginal biocenosis, which is a condition for preventing relapse. A two-stage treatment for BV was studied using Limenda and Bioselak. The use of the combined antimicrobial drug Limenda at the first stage of treatment of BV showed a high clinical effect (100%) with confirmation of cure according to microscopic examination (97.9%). But after the completion of antimicrobial therapy, only in 29.2% of cases the restoration of the rod vaginal microflora was noted. The local use of the probiotic Bioselak at the second stage of treatment ensured the restoration of the biocenosis in all patients (100%) and a long relapse-free period. The high clinical effectiveness of the proposed scheme allows us to recommend it for the treatment of BV and the prevention of relapse. Key words: bacterial vaginosis, vaginal biocenosis, relapse prevention, local probiotic, Limenda, Bioselak.

La industria alimentaria alrededor del mundo tiene la necesidad de sustituir los aditivos artificiales o sintéticos por alternativas naturales, debido a la demanda de los consumidores de ingredientes alimentarios naturales. En la búsqueda de proponer alternativas que coadyuven a esta problemática se evaluó la actividad hemolítica, antimicrobiana y antioxidante, así como la concentración de compuestos fenólicos totales y antocianinas monoméricas totales de extractos acuosos de cálices de jamaica de nueve variedades, cultivadas en los estados mexicanos Nayarit, Oaxaca y Puebla. La mayor concentración de compuestos fenólicos totales (CFT), antocianinas monoméricas totales (AMT) y actividad antioxidante por diversos métodos (DPPH·, ABTS·+, FRAP y ORAC) la presentó el extracto de la variedad de jamaica ‘cruza negra’ de Nayarit, la cual a una concentración de 20,000 µg/mL promovió una reducción en la velocidad de crecimiento de una cepa de Escherichia coli hasta en 51 % respecto al control. Por otra parte, la actividad hemolítica se mantuvo cercana al 1% aún con una concentración de 6000 µg de CFT/mL. Por lo anterior, se puede proponer el uso de los extractos acuosos de cálices de jamaica como un aditivo alimentario de origen natural, antioxidante, antimicrobiano y con muy baja actividad hemolítica.

Authors:   Shanghai University of Political Science and Law, Shanghai, China, Pinjie Sun
Published: November 2020

This research analyzes the functions of university think-tanks from the perspective of the Chinese government, in particular their role in generating knowledge for governmental decision-making. It also reveals the achievements and problems of the development model of Chinese university think-tanks. Methodologically, this study relies on analysis and interpretation of the key policy documents of the Chinese government, the public information of some university think-tanks and the research results and data of professional think-tank research institutions. The study found that the Chinese government is trying to incorporate university think-tanks into the «Holistic Knowledge» production link and thus turn them into professional decision-making knowledge supply institutions. As a result, Chinese university think-tanks will perform the role of t bridges between academic knowledge production and generation of knowledge for the government’s decision-making, ensuring the necessary flexibility between these two processes. However, the drawback of such policy is that it limits the autonomy of university think-tanks and their social influence.

This article discusses the results of a field study conducted in 2019 at Tomsk State University (TSU) and Tyumen State University (TyumSU). The purpose of the study is to investigate the motivations behind educators’ choice of their profession and the aspects they say as its advantages and disadvantages. Methodologically, the study is based on 43 in-depth interviews with lecturers of TSU and TyumSU. These universities are located in Siberian cities and are among the group of the leading higher education institutions in Russia. The study shows that the lecturers associate the benefits of work at the university with the opportunities provided by the ‘5-100 Project’ to attain the world standards; good working conditions; prestige of work at a reputable university; stability of university employment; feeling of belonging to the academic; and so on. Most educators are dissatisfied with such aspects of university work as bureaucratization; redundancies; short-term contracts; the lack of transparency and inefficiency in funds distribution; and irregular working hours. We found that despite some divergence of views, the faculty of the TSU and TyumSU share a lot of opinions on the advantages and disadvantages of university work. Thus, the cases of the two Siberian universities provide us with the insights into a larger picture of the Russian system of higher education. These findings can be useful for HR services of universities for recruiting and retaining personnel.

This article discusses the problems and prospects of university-enterprise cooperation in the sphere of engineer training, in particular the phenomenon of ‘base departments’. The article focuses on the case of the Aeronautical Engineering Department of the Don State Technical University, whose purpose is to train engineering staff for the partner aerospace enterprise PAO Rostvertol. The study draws from the empirical data collected through the sociological survey of the Department’s faculty and students as well as the partner enterprise’s employees (graduates) and managers. Methodologically and conceptually, the study relies on the systemic approach, stakeholder theory, theory of competencies and the method of situation analysis. We sought to evaluate the sufficiency and relevance of the hard and soft skills that students developed during their studies at the Department. It is shown that the Department has managed to provide its students and graduates with a sufficient level of hard and soft skills to enhance their employability in aeronautical engineering. The Department uses a dual education system, which combines work-based learning with theoretical courses. In future, it is planned to expand this system and maximize student engagement by encouraging students to do their individual research projects at the partner enterprise. The research findings may be used to develop strategies of university-enterprise cooperation and to assess the efficiency of the training process.

Resumo Os fenômenos relacionados ao uso de drogas constituem um campo heterogêneo e polissêmico, a partir do qual se constroem diferentes objetos, identidades e práticas sociais. Este artigo apresenta uma pesquisa documental, baseada na teoria das representações sociais, cujo objetivo foi analisar o campo representacional das drogas em comunicações midiáticas. O material foi composto por 4.516 matérias de um jornal de ampla circulação no Brasil que tinham como tema central questões relacionadas às drogas. Com auxílio do software Iramuteq, realizou-se uma análise lexicométrica visando reconstituir classes lexicais relacionadas a dimensões específicas do campo. Oito classes foram interpretadas, categorizadas e discutidas. Os resultados permitiram identificar três eixos temáticos: regulação sociopolítica do uso, produção e circulação das drogas; uso de drogas, dependência e saúde; polícia e guerra às drogas no Brasil. A discussão evidencia dimensões que conferem sentido a processos político-legais, relações internacionais, movimentos sociais, entretenimento, práticas terapêuticas, políticas públicas, violência, criminalidade e exclusão. Além disso, os fenômenos do campo guardam relação com categorias sociais típicas (e.g., usuários e traficantes); formas de desvio (e.g., dependência e crime); e práticas sociais em saúde e segurança pública (e.g., tratamento e prisão). Compreende-se que os conteúdos difundidos nessas comunicações atuam na criação de quadros simbólicos de referência que podem influenciar a orientação de práticas sociais e tomadas de posição diante dos fenômenos relacionados ao uso de drogas.
Gamifying Portuguese Language Learning: A Case Study Examining a Quest-Based Website to Prompt Oral Production and Interaction in Learners of Portuguese L2
Authors: Xavier Carla Cristina Munhoz
Published: November 2020

ABSTRACT One of the major challenges when teaching second language learners is to maintain them motivated and eager to learn and work on the proposed activity. The literature showed that a combination of social constructivism and technology-integrated learning is crucial for achieving the goals set by modern educational objectives. However, in order to have a robust response from students, one should take into account the psychological aspect of intrinsic and extrinsic motivation. This paper proposes a gamified activity in Portuguese L2 that aims to intensify the students’ motivation. Ten undergraduate students participated in this study. Their responses show that novel studies based on awards and gamification can boost the students’ motivation when learning Portuguese.

RESUMO Introdução: Assumindo-se que erros são, na verdade, tentativas de acertos, podendo marcar conflitos da criança com o sistema ortográfico, investigou-se o registro ortográfico de dois dos fonemas que remetem à classe das líquidas: /l/ e /ɾ/. Objetivo: (1) comparar a acurácia ortográfica, nas posições silábicas de ataque complexo e de coda, da grafia dos fonemas /l/ e /ɾ/; (2) verificar, dentre os erros, seus tipos mais frequentes. Método: Foram analisadas 53 produções textuais de crianças do 1º ano do ciclo I do ensino fundamental (EF) de uma escola pública do interior de São Paulo. Para responder aos objetivos, inicialmente foram separadas todas as ocorrências dos fonemas /l/ e /ɾ/ na posição de ataque complexo e de coda silábica. Posteriormente, os registros foram categorizados como acertos e erros. Os erros foram, ainda, classificados como omissão, transposição e substituição. Resultados: No ataque silábico complexo e na coda silábica, foi encontrado maior número de acertos quando comparado com o número de erros. Quanto aos tipos de erros, no ataque complexo, todos corresponderam a omissões; já na coda, as omissões prevaleceram, seguidas das substituições e das transposições. Conclusão: Os resultados sugerem que a percepção que a criança tem das relações entre fonemas e grafemas não depende diretamente dessas relações, já que essa correspondência pode ser afetada por outros aspectos fonológicos desconsiderados nessas relações, como as posições silábicas.
Correlations between the concepts of disinformation and Fogg’s Behavior Model
Authors: MURIEL-TORRADO Enrique , PEREIRA Danielle Borges
Published: November 2020

Abstract As connectivity and interactions on the internet and social media grew easier, it made it possible for any individual to create and disseminate information or news as desired, which resulted in the growth of disinformation, leading to questions of how human beings can be manipulated by false information. The main objective of this research is to correlate the concepts of false news and misinformation with Fogg’s Behavior Model. By considering the correlation between the definitions and concepts applied by the selected bodies and institutions and the factors of Fogg’s Behavior Model, we conclude that all the definitions have aspects correlated with the factors raised by Fogg for the persuasion toward a desired behavior, thus showing how false information can be used to manipulate individuals who are likely to believe in a certain topic, those who do not have knowledge of verifiability procedures for misinformation or those who have already been affected by informational fatigue.

The article is devoted to solving the urgent problem of increasing the efficiency of methods for calculating the electric field. A meshless method for calculating disturbed stationary electric fields is proposed, based on the use of point electric moments. In this case, the accuracy of the calculation of the potential increases and the numerical instability caused by the error in the difference between close values when calculating the potential of the dipole is excluded. Replacing sources with distributed parameters is performed by a set of point sources. This makes it possible to exclude the operations of integration over the volume and surface, replacing them by summing the contributions of the moments. The absence of a grid significantly reduces the total number of un-knowns. The application of the method is shown by examples. The electric fields disturbed by the introduction of a dielectric cylinder, a conducting cylinder and a conducting rod of rectangular cross-section into a uniform field are calculated. The results obtained show the high efficiency of the developed method.

Unclosed part of an electric circuit exerts the so-called self-action a result of which is the action of the un-closed conductor on itself. The same relates to the rotary moment described by the self-torque. The self-force and self-torque are very small for conductors of simple form. For the spiral-shape conductor with large number of wraps and with the increased lead between wraps, the self-torque is found to be extremely large

The algorithm of structural and parametric synthesis of automatic control systems for limitedly uncertain non-linear objects with unstable balance status and right own values in their exit matrix is proposed. The pecu-liarity of the structural synthesis algorithm is that synthesized automatic control systems use differential com-pensating connection with two components. The signal of one of them is proportional to the signal of disa-greement between the required and measured values of the state vector of the system. A signal of another com-ponent is formed by the sign-operated integral feedback on the module of the control influence. The algorithm of parametric synthesis is reduced to solving the problem at a conditional minimum of integral regulatory error when limiting the characteristic frequency multi-member module to an algorithmically linearized system.

The problem of determining the control action, the optimal number and combination of hydraulic cylinders required to guide the tunnel shield along the project axis of the tunnel with the required accuracy is consid-ered. An algorithm for the formation of a combination of hydraulic cylinders for moving the shield is applied, creating an effort in accordance with the magnitude of the control action, determined by the deflection of the shield in the vertical and horizontal planes. Analytical expressions for determining the control parameters are given. Modeling the process of controlling the movement of the tunneling shield showed that the proposed method provides the required accuracy of guiding the tunneling shield in accordance with the design direction.

The results of mathematical modeling show that during phase failure in power supply systems with asyn-chronous and synchronous motors is appear power flows interchange between individual motors and the sup-ply network, which makes it difficult to perform selective protection against exceeding the inverse sequence currents by known methods. Proposed protection on the supply input and on individual motors, based on the control of the current level of the inverse sequence and the absence of current in one of the phases. This protec-tion on the supply input is also can used as start of fast-acting automatic transfer switch. The results of success-ful tests of protection are presented.

Influence Estimation of the On-Load Tap-Changing Transformeron the Currents in Schemes of Ice Melting on Overhead Transmission Lines
Authors:   Platov South-Russian State Polytechnic University (NPI), Zasypkin (jr.) Alexander
Published: November 2020

The influence of regulated under load transformer's (on-load tap-changing transformer) ratio and imped-ance on the short circuits’ currents and currents in the schemes of ice melting with AC and DC current is ana-lyzed. Accounting for changes in the transformer ratio is not difficult as it is provided in the technical data for all branches (tap positions). The transformer resistances used in the calculations, which are reduced to the un-regulated side of the transformer, are proportional to the short-circuit (SC) voltages. SC voltages are known, according to GOST, only for three tap positions - main (middle) and two extreme (top and bottom) positions, and for other tap positions are determined approximately according to different methods. It is shown on the typical example, that the error of the melting current calculation is significantly less than the error of the ap-proximated transformer's resistance calculation by the method of linear interpolation of resistances, the error of which for different types of on-load tap-changing transformers does not exceed 3 %.

The first group included newborn animals. The sec-ond group included animals of one month. The third group included young animals of five or six months. The fourth group consist-ed of goats, starting from one year old. The age of the animals was determined according to the data obtained from monitor cards. A total of twenty heads were examined. Based on our research, primarily we established that the change in the topography of the right and left kidney in Anglo-Nubian goats exists mainly because of the displacement of the caudal end of the kidney cranially at a dis-tance equal to the length of one or two verte-brae. In both kidneys, the anterior or cranial end does not have a pronounced displace-ment. Studying kidney syntopia in goats, we found confirmation that the caudal hollow vein together with the abdominal aorta lie dorsally from the kidneys, while the rumen sac is located laterocranially from the left kidney, when it overflows, a slight change in the topography of the kidney can be visual-ized, and parts of the duodenum are located laterocranially. The data we have established confirm the similarity of the Anglo-Nubian breed of goats with goats of other breeds. By studying the vascularization of the kidneys in the Anglo-Nubian goat breed, we con-firmed that the renal blood supply is pro-duced by two renal arteries, each of which is directed to the corresponding kidney "L2-L3". We also found that the severe increase in the diameter of the renal arteries occurs in these animals from 1 to 6 months.

Since the clinical manifestation of enteri-tis of various etiologies has a similar picture, and parvovirus enteritis has a high mortality rate, early diagnosis of this disease is im-portant. A number of publications demon-strate changes in ultrasound parameters dur-ing inflammatory bowel diseases. The article is devoted to comparison of ultrasound and histological changes in the wall of the stom-ach and small intestine with parvovirus en-teritis in order to distinguish the most spe-cific ultrasound markers. Object of the study – 53 dogs of mixed breeds of both sexe with a confirmed diagnosis of parvovirus enteri-tis by polymerase chain reaction in real time from the age of 6 weeks to 7 months. Re-search were conducted at the Stavropol Vet-erinary Center named after Pirogov and Vet-erinary Center of the Stavropol State Agrari-an University, by the use of SIUI Apogee 1100 Omni scanner (Shantou Institute of Ultrasonic Instruments Co., Ltd., Guang-dong, China), according to the generally accepted method using a multi-frequency linear sensor with a frequency of 5-13 MHz in B-mode. The most characteristic ultrason- ic manifestations of canine parvovirus enteri-tis are hypotension and ectasia of the stom-ach and loops of the small intestine with the presence of anechogenic fluid content in their cavity; thickening of the surface layer of the mucosa in the form of a hyperechoic strip, a decrease in the ratio of the mucous layer to the entire wall thickness of the duo-denum and jejunum by more than 2 times and increased echogenicity of the mucous layer. This picture is a result of the partial necrosis and desquamation of villi, prolifera-tion of cell infiltrate in the mucous layer itself, consisting of lymphocytes, macro-phages, a small number of histiocytes and fibroblasts.

According to experimental data, in the Re-public of Dagestan, the cows examined in the mountains are more infested than on the lowland. EI is 28 percent. The research re-sults showed that invasion with dicroceliosis had a clear picture associated with an in-crease in the intensity of invasion in adult cows and late fall in young animals. In mixed helminthiases of cattle, the main source of dicroceliosis and echinococcosis in the Chechen Republic,when the animals are kept on farms with stall-grazing and distant-grazing in alpine meadows, mainly are in-fested young animals, aged from one to two years, and adult cows. With distant pasture maintenance, in calves aged three to seven months, mixt- invasion of dicroceliosis and echinococcosis were not observed; in calves from seven months. up to a year were detected EI - 20.0 with AI of dicrocelium 240.9 ± 19.2ex. and II echino-coccus AI 16.7 ± 1.8 ind./ goal; in young animals from one year to two years, accord-ing to EI-40.0% (AI dicrocelium 391.4 ± 37.5 specimens and echinococcus 28.9 ± 3.2 specimens /head); found in cows with EI - 60.0% (AI dicrocelium 587.6 ± 38.2 ind. and II echinococcus 47.4 ± 3.9 ind. / goal). On average, the intensity of mixtinvasion of all age groups of cattle were, respectively, EI - 20.0%(AI dicroceliosis 203.3 ± 15.8 ind. and II echinococcosis 15.5 ± 1.5 ind. / head). The obtained data of the extense invasion and intensification of mixed helminthiases of dicroceliosis and echinococcosis in cattle and the biological nature of the infection are completely dependent on the technology of keeping both young animals and adult ani-mals.

In recent years, sheep farms in the Lenin-grad region began to increase import from abroad of sheep breed "Dorper" This breed were bred in the 1930s in the deserts of South Africa. Later this breed began to be exported to Australia, the UK and in small quantities to Russia. Breed "Dorper" very precocious, young quickly gaining live weight up to 500 grams per day. Adult sheep reach a weight up to 90 kg or more. Rams can be used as producers from 5 months. Taking into account that, like all meat breeds of sheep, dorpers are very sensitive to drafts, high humidity, dampness in sheep-fields. The object of research- breeding sheep breed "Dorper". The research was carried out in the farm "SP A. Krylov" Leningrad re-gion. Two groups of 3 heads each were formed to treat the rams. In the scheme of treatment of animals of the first (experimental) group, a finely dispersed soft powder (manganese-acid potassium+copper sulfate+ boric acid + streptocide 1:1:3:5) was used, which was applied on the ulcer with the help of a powder blower. For animals of the second group were applied "Konkov ointment". For the rams of both groups were used a short novocaine blockade with an antibiotic (streptomycin) directly under the pathological focus. Repeated treatments were carried out after 3,6,12 16 days. It should be noted that balanoposthitis in rams appears mainly in autumn and spring. The use of complex powders in rams with ulcerative balanoposthitis showed positive dynamics of the course of this disease, re-duces the healing time of the ulcer surface by 3-4 days, compared to the conventional treatment in the farm with the use of "Konkov ointment

The invasion of small cattle by moniezio-sis in the Russian Federation occurs every-where and causes great economic damage to sheep farms, leading to the death of lambs and to decrease of meat and wool quality. In lambs infected with monieziosis, there is a lack in weight gain of 1.5 – 3 kg, as well as a decrease in the production of quality wool from a sheep to one kilogram. Damage from intestinal helminthozises, in particular ces-todosis, leads to death and forced slaughter, poor-quality wool and non-viable offspring. The dynamics of the epizootological process, patterns of the spread and course of the inva-sion in the North Caucasus region remain poorly studied, especially of the intestinal cestodes, namely monieziosis of small cat-tle. Taking into account the climate condi-tions of the Chechen Republic, and the lack of the knowledge of invasion, it is nec-essary to study natogeorgia and species com-position of causative agents of monieziosis of small ruminants, particularly sheep. The purpose of our research was to study the ecology and prevalence of monieziosis of sheep of different age groups in the plains of the Chechen Republic, to identify the species and age groups of monieziosis. In the flat areas of the Chechen Republic, infection with monieziosis determines the ecological balance of the parasitic structures of the ces-todes. The extensiveness and intensity of M. exports are compared with M. benedeni more. In lowland farms, lambs of small cat-tle have an EI of 12.9 – 16.7% with an EI of 2.2 ECZ / head.; young animals 9.1-11.1% and 2.1 ex/head.; in sheep, 4, 9 – 6.1% and 1.0-1.3 ex / head. EI M. benedeni lambs 7,3 – 8,1, AI-1,2 – 1,3 ex/goal.; young EI-5.6 -6.5% II-1ekz / goal. M. expansa was not found in mature sheep. In lowland areas, sheep monieziosis is observed with focal prevalence in all the farms studied by us during the year.

In the study, the influence of the drug "Vetmedin" on the heart condition of the dogs of small breeds, suffering from chronic cordiac insufficiency, was studied. In the control group of animals , the average thick-ness of the interventricular septum in the diastole stage (MLPd, mm) was 3.36 ± 0.44 mm, and in the test group 3.41 ± 0.38 mm. The average value of the thickness of the ventricular septum in the systole stage (MLPS, mm) was 4.36 ± 0.52 mm in the control and 4.33 ± 0.39 mm in the test group. The thickness of the posterior wall of the left ventricle in the diastole stage (CDFd, mm) in healthy dogs was 3.66 ± 0.47 mm, and in the test group - 3.58 ± 0.37 mm. The thickness of the posterior wall of the left ventricle at the systole stage (LFRA, mm) was 5.34 ± 0.40 mm and 5.48 ± 0.33 mm, respectively. The results were lower than the minimum acceptable physiological values for dogs and showed excessive tension of heart chambers in sick animals. It was found that oral ad-ministration of "Vetmedin" twice a day, at a daily dosage of 0.5 mg /kg of body weight for 30 days, contributed to the improvement of the general condition of animals, increase of their physical activity and decrease of blood pressure at the average on the 26.9% and brought it closer to physiological values. Ultrasound diagnosis of the heart allowed to conclude that this drug contributes to im-provement of heart muscle in dogs and leads to normalization of its wall thickness already on the 30th day of administration.
