Published: March 2021

Work purpose: improving effectiveness and quality in the control of engineering processes of tool working in the plasma generator of a glow discharge based on neural network monitoring. Investigation methods: use of nature and regularities of human thought at the development of the computer model of a neural network allowed realizing a cybernetic approach at real production object work modeling with the purpose of increasing effectiveness and quality of control at the management based on neural network monitoring. The essence of the modeling method consists in the development of such algorithms and programs which imitate the behavior of the plasma generator of a glow discharge, its characteristics in the structure, volume and field of technological parameter use essential for the research. Investigation results: the system offered for the control of effectiveness and quality of realizable engineering processes during plasma generator work based on neural network monitoring allows ensuring good repeatability of the results on tool strengthening. The defined sequence of engineering process operations of product working in the plasma generator of a glow discharge ensures the formation of specified structure and micro-hardness on the surface of products under processing. In the system offered control and management are formed on the basis of a neural network approach and imitate system behavior at all machining steps of processing. The results of continuous monitoring are shown with the essential discontinuity in on-line modes in the form of values and deviations of controlled technological parameters of the working process on the display of an electronic control unit. The generality and simultaneous uniqueness of the properties of continuous monitoring systems on applicability for real technological object control and range extension of problems solved with their help transforms them into compulsory means for complex automated device equipment. The modeling algorithm offered at the formation of an automated system to control effectiveness and quality in functioning plasma generator of a glow discharge for strengthening a wide range of tools with different profiles with machining steps differed in character of plasma impact, duration and their realization priority allowed optimizing the repeatability of results in ensuring specified properties in surface-bounded layers that satisfies conditions of the automated technological environment.

Bir Tefsir Kaynağı Olarak İbn Hibbân’ın es-Sîretü’n-Nebeviyyesi
Authors: ATMACA Gökhan
Published: March 2021

Kur’an’ın anlaşılmasında ilk muhatapların Kur’an’la olan irtibatları yegânedir. Bu yönüyle sonraki nesilleri, bu ilk nesle ve nüzûl ortamına ulaştıran her bir eser özünde tefsir ya da türevi bir hüviyete sahip olmasa bile değerlidir. İşte bu noktada siyer ya da ilk dönem Kur’an’ın muhataplarının sîretlerini ihtiva eden kaynaklar tefsir ilmi açısından kıymetli olmaktadır. Bu çerçevede önemli kaynaklardan biri de İbn Hibbân’ın es-Sîretü’n-Nebeviyye ve Ahbâru’l-Hulefâ adlı eseridir. İbn Hibbân’ın vefatının hicrî 354 olduğu -ilk dönemlerde tefsir telif eden müfessirlerle aynı dönemde yaşadığı- da dikkate alındığında eserinin Kur’an’ı anlamada kaynak olabileceği gerçeği yadsınamaz. Söz konusu saikle bu araştırmada, İbn Hibbân’ın es-Sîretü’n-Nebeviyye’si tefsir ilmi açısından incelenmiştir. İbn Hibbân, yaşadığı dönemin önde gelen âlimlerinden olup meşhur eserlerinden es-Siretü’n-Nebeviyye erken dönem kaynaklarındandır. es-Sîretü’n-Nebeviyye her ne kadar biyografik bir eser olsa da içerisinde yer alan haberlerin bir kısmının Kur’ân ve tefsirle ilgili olması, onu tefsir açısından da önemli kılmaktadır. Çalışmamızda küçük hacmine rağmen söz konusu eserde Kur’an’ın anlaşılmasına dönük bilgilerin yer aldığı görülmüştür. İbn Hibbân eserinde ana tema olarak Hz. Peygamber’in yaşantısını konu edindiği için kronolojik bir sıra takip etmiş-tir. Dolayısıyla Resulullah’ın ilk vahy tecrübesi ve buna dönük yaşantıları eserde ele alınmıştır. Eserde zaman zaman çeşitli ayetlere atıflar bulunmaktadır. Böylece ayetlerin mekkî ya da medenî oluşları, müp-hemleri, sebeb-i nüzûlleri ya da yorumları konu edinilmiştir. Bu husus eseri tefsir ilmi açısından ele alıp incelemeye müsait hale getirmektedir.
The Effect of Exposure to (Non-)Like-Minded Information on the Use of Political Incivility on Twitter
Authors: Nishi Kohei
Published: March 2021

Does exposure to like- and non-like-minded information lead to political incivility? Few previous studies have investigated this question, and the results have been mixed. There are two conflicting possibilities: (i) if individuals are frequently exposed to like-minded political information, their preexisting beliefs are reinforced and they are more likely to use uncivil language, and (ii) if individuals are frequently exposed to non-like-minded information, they often feel negative emotions and therefore are more likely to be uncivil. To evaluate these two competing hypotheses, the present study analyzes data from Japanese Twitter using a semi-supervised machine learning method. The results show that individuals who are exposed to non-like-minded information are more prone to political incivility.

FAM227A is differentially expressed in the lymph node metastases of patients with breast cancer.
Authors: Mamoor Shahan
Published: March 2021

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the breast and the brain reside the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that family with sequence similarity 227 member A, FAM227A, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Analysis of a separate microarray dataset revealed that FAM227A was also differentially expressed in brain metastatic tissues (5). FAM227A mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Modulation of FAM227A expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.

AbstractThe territory of the Republic of Indonesia is very wide covering many large and small islands, so it is not possible if everything will be managed entirely by the Government which is domiciled in the State Capital, to manage the administration of state government to all corners of the country, it is necessary to form a regional government. Local governments and village governments have shifted from a centralized system of government to a decentralized one so that providing services to the public is closer and can be done optimally. This implementation brings a lot of hope to the improvement, management, and quality of local performance. This study aims to examine the role of the Village Consultative Body (BPD) in the Village Government and what factors hinder the role of the Village Consultative Body (BPD) in the Village Government in Karang Jaya Village. This research is a descriptive type of research, namely a study that describes the phenomena of a BPD cooperation management with the village head, thus the approach used is the normative approach. The results show that the BPD in Karang Jaya village has not been able to carry out its role optimally because the human resources of BPD members are still low, especially in the education sector so that in carrying out its roles and functions the BPD does not understand what to do concerning the control and supervisory functions. becomes its authority in controlling and supervising the performance of the Village Government / Village Head.Keywords: BPD, Karang Jaya, Role

How (Not) To Test Theory With Data: Illustrations from Walasek, Mullet and Stewart (2021)
Authors: André Quentin , de Langhe Bart
Published: March 2021

André and de Langhe (2021) pointed out that Walasek and Stewart (2015) estimated loss aversion on different lotteries in different conditions. Because of this flaw in the experimental design, their results should not be taken as evidence that loss aversion can disappear and reverse, or that decision by sampling is the origin of loss aversion. In their response to André and de Langhe (2021), Walasek, Mullett and Stewart (2021) defend the link between decision by sampling and loss aversion. We take their response as an opportunity to emphasize three guiding principles when testing theory with data: 1) Look for data that are uniquely predicted by the theory, 2) Do not ignore data that contradict the theory, and 3) If an experiment is flawed, fix it. In light of these principles, we do not believe that Walasek, Mullett, and Stewart (2021) provide new insights about the origin and stability of loss aversion.
Covariate Selection for Estimating Individual Treatment Effects in Psychotherapy Research: A Simulation Study and Empirical Example
Authors: Wester Robin Anno , Rubel Julian , Mayer Axel
Published: March 2021

Estimating individual treatment effects (ITEs) is crucial to personalized psychotherapy. It depends on identifying all covariates that interact with treatment, a challenging task considering the many patient characteristics hypothesized to influence treatment outcome. The goal of this study was to compare different covariate selection strategies and their consequences of estimating ITEs. A Monte Carlo simulation was conducted to compare stepwise regression with and without cross-validation and shrinkage methods. The study was designed to mimic the setting of psychotherapy studies. No single covariate selection strategy dominated all others across all factor-level combinations and on all performance measures. Lasso showed the most accurate out-of-sample predictions, identified the highest number of true treatment-covariate interactions, and estimated ITEs with the highest precision across the most conditions. Domain backward stepwise regression and backward stepwise regression using BIC were least biased in estimating variance of ITEs across the most conditions.

The third gender is in many cultures made up of an individual, considered male at the time of birth, but change on feminine gender role or sexual role when they grow up and vice versa third genders and homosexual are the group of people who are not allowed to talk about their sexual and emotional preferences in public. The study health problems faced by the third gender of Naulo Bihani, Pokhara raises the genuine questions regarding the demographic and health condition of that third gender. All 60 residing there were the sample of data collection through census method by using interview schedule with open and close questions. Observation and KII were done with the management committee of Naulo Bihani, Pokhara, and sister organization of Blue Dimond Society Kathmandu. It attempts to raise consciousness of human rights on the sexual and gender minorities, witness violence, abuse and rape. All the respondents suffered from viral and bacterial diseases; 78.33 percent suffered from protozoa infection. Only fifteen percent respondents were suffered from Syphilis. But no one was suffered from HIV AIDS. They felt social discrimination and tell them Hijara and so on. It is justification to advocate their right in the society so the researcher tried to make a research on the topic.

Corporate Governance Mechanisms in Commercial Banks of Nepal
Authors: Baral Ravindra Prasad
Published: March 2021

Corporate governance in banking sector has received great attention among policymakers, practitioners and academicians in Nepal due to governance failures in some financial institutions in recent period. This study attempts to examine the corporate governance mechanisms adopted by Nepalese commercial banks by using a panel data of 30 commercial banks from 2012 to 2016. The internal corporate governance mechanisms are board structure and composition, board committees, director independence, transparency and disclosure, director remuneration, and shareholders rights. The study employs ANOVA test to examine differences in corporate governance mechanisms among state-owned, joint venture, and domestic banks. The study findings reveal that the corporate governance practices in financial institutions of Nepal is somewhat satisfactory; however, significant improvements are required especially in case of state-owned banks and local private banks. In order to achieve the policy of government of Nepal to enhance financial system stability, one of the major areas for policy focus should be to promote enhancement of corporate governance standards in the financial institutions as the stability of the banking sector depends largely on corporate governance practices they adopt. Promoting director independence, improving transparency and disclosure, and enhancing shareholders’ right are found to be important for improving standard of corporate governance in Nepal.
Dinámicas del viento en quintas de cítricos y daño en los frutos
Authors: Cataldo José , Durañona Valeria , Pienika Rodolfo , Gravina Alfredo
Published: March 2021

En Uruguay las quintas de cítricos están protegidas con mallas naturales, conformadas por árboles altos. Si bien se consigue disminuir la velocidad media del viento, no se logra una disminución de la cantidad de fruta descartada debido al daño por viento. El roce de las hojas sería lo que genera el mayor daño sobre la superficie en las primeras etapas de crecimiento del fruto. Se realizó un trabajo de campo en un cuadro de una plantación de cítricos, en el que se instalaron mallas de manera de lograr una protección parcial del mismo. En las zonas protegidas por estas mallas se apreció un aumento de la cantidad de fruta de calidad exportable. A diferencia de las barreras naturales, cuando el viento escurre alrededor de estas mallas plásticas se produce turbulencia con escalas del tamaño de las hojas de los árboles y aún menores. Se estudió un árbol cítrico en el túnel de viento, con flujos de velocidad media entre 1 m/s y 6 m/s, y de diferente nivel de energía contenida en las estructuras vorticosas correspondientes a longitudes del tamaño de las hojas y menores. Para una velocidad media determinada, cuando el contenido de energía de las pequeñas escalas de la turbulencia era elevado, las hojas se movieron con una amplitud significativamente mayor a cuando el flujo presentó baja energía en las pequeñas escalas de la turbulencia. Esto lleva a concluir que la hoja permanecería alejada del fruto un tiempo significativamente mayor cuanto más elevada sea la energía contenida en las pequeñas escalas de la turbulencia, disminuyendo así la acción mecánica de las hojas y el consiguiente daño.

La productividad primaria neta aérea (PPNA) es uno de los atributos ecosistémicos más importantes, siendo el principal control de la carga ganadera en pastizales. Tradicionalmente se ha estimado a partir de cortes periódicos de biomasa. La información espectral permite estimar la PPNA a bajo costo y en tiempo real sobre áreas extensas. Para ello se requiere la calibración de modelos que relacionen información espectral con la PPNA estimada mediante cortes de biomasa a campo, cuantificando un factor clave en esta relación: la eficiencia de conversión de la radiación en biomasa (Eficiencia en el Uso de la Radiación: EUR). En este trabajo combinamos datos de PPNA estimada a campo, con datos obtenidos de imágenes de satélite y estaciones meteorológicas, para estimar EUR y generar modelos de estimación de la PPNA en tiempo real en pastizales naturales con y sin siembras en cobertura de leguminosas, en la región de Sierras y Lomadas del Este. La EUR para pastizales naturales fue de 0,24 g MS/MJ (Materia Seca/Mega Joules), mientras que en los sitios intersembrados la EUR fue aproximadamente el doble, dependiendo del sistema analizado.

Fallas horizontales como potenciales acuíferos en el departamento de Florida Primera parte: cabalgadura paleoproterozoica del arroyo Castro
Authors: Bossi Jorge , Caggiano Raquel , Piñeyro Daniel
Published: March 2021

Desde 1996 Bossi y Piñeyro plantearon la posibilidad de contactos subhorizontales entre las unidades geológicas del Terreno Piedra Alta, de grado metamórfico y asociaciones litológicas muy diferentes. En un taller itinerante se descartó la idea por falta de milonitas horizontales en los planos propuestos, que contenían pegmatitas y/o microgranitos laminares a muscovita, de muy bajo buzamiento. La posibilidad de que ese magma peraluminoso actuara como lubricante y permitiera desplazamientos significativos sin grandes esfuerzos hizo que el tema se retomara, aprovechando 850 observaciones del «Proyecto Vulcanitas Arqueanas» y 750 observaciones del «Proyecto Terreno Piedra Alta». Las observaciones georeferenciadas fueron ubicadas sobre cartas topográficas 1/50.000 y las zonas con mayor densidad de datos fueron aerofotointerpretadas a escala 1/40.000 y relevadas geológicamente a diferentes escalas. Quedó confirmada la cabalgadura de la faja granítica Florida sobre el cinturón San José y se descubrió la cabalgadura del Arroyo Castro con un buzamiento al norte de 2 %.
Potential Soil Quality Impact of Harvesting Crop Residues for Biofuels
Authors: Karlen Douglas L.
Published: March 2021

We are in one of the greatest technological, environmental and social transitions since the industrial revolution, as we strive to replace fossil energy with renewable biomass resources. My objectives are to (1) briefly review increased public interest in harvesting crop residues as feedstock for bioenergy, (2) discuss the work soil scientists must do to address those interests, and (3) examine how soil quality assessment can be used to help quantify soil biological, chemical and physical response to this transition. Rising global energy demand, dependence on unstable imports, volatility in price, and increasing public concern regarding fossil fuel combustion effects on global climate change are among the factors leading to an increased interest in development and use of renewable biomass sources for energy production. Although controlling soil erosion by wind and water is no less important than in the past, it is not the only factor that needs to be considered when evaluating the sustainability of land management practices including harvest of crop residues as bioenergy feedstock. The concept of soil quality assessment is reviewed and the Soil Management Assessment Framework (SMAF) is used to illustrate how such assessments can be used for assessing impacts of harvesting crop residue as feedstock for bioenergy production. Preliminary results of the SMAF assessment show that soil organic carbon (SOC) is one of the lower scoring indicators and therefore needs to be monitored closely. Innovative soil and crop management strategies, including a landscape vision are offered as ideas for achieving sustainable food, feed, fiber, and energy production.

Authors: Punschke Karina , Mayans María
Published: March 2021

Las bacterias del género Herbaspirillum spp. endófitas promueven el crecimiento vegetal, fijan nitrógeno y producen fitohormonas. La combinación de estos mecanismos puede contribuir a mejorar la eficiencia del uso de fertilizantes nitrogenados en cultivos de importancia agrícola. El objetivo del presente trabajo fue seleccionar cepas de la bacteria diazotrófica Herbaspirillum spp. para promover el crecimiento en plantas de arroz. Se aislaron 113 endófitos diazotróficos de la parte aérea de plantas de arroz de diferentes variedades y estadios fenológicos. Once fueron identificados como presuntos Herbaspirillum spp. según sus características morfológicas y fisiológicas. De éstos, dos aislamientos (9.4 y 4.2) produjeron aumentos significativos en la biomasa aérea de plantas de arroz crecidas en condiciones controladas. Ambos aislamientos se ensayaron en plantas cultivadas en invernáculo en ausencia y presencia de urea. La biomasa radicular de las plantas inoculadas con el aislamiento 4.2 fue significativamente mayor tanto en presencia como en ausencia del 50% de la dosis de urea utilizada por los productores (100 kg/ha). Se evaluó el efecto de la inoculación de semillas de arroz con el aislamiento 4.2 en campo. Se incluyeron tratamientos inoculados y sin inocular con diferentes dosis de fertilización nitrogenada. Se obtuvo una mejora del 15% en el rendimiento de los cultivos inoculados respecto a los testigos sin inocular. La secuenciación del gen 16S ARNr indicó que la cepa 4.2 pertenece al género Herbaspirillum spp. Se concluye que la cepa 4.2 de Herbaspirillum spp. posee potencial como biofertilizante en arroz, maximizando el aprovechamiento de los recursos.

El objetivo de este trabajo fue determinar el efecto de distintas combinaciones, concentraciones y número de aplicaciones de GA3 , CuSO4 y ANA en la germinación de polen in vitro, crecimiento del tubo polínico en flores tratadas individualmente y la inducción de partenocarpia en campo de la mandarina autocompatible ‘Montenegrina’. El polen se colectó y sembró en medio de cultivo, conformándose nueve tratamientos de distintas dosis y combinaciones de los tres productos. Se seleccionaron botones florales previo a antesis y se les aplicó ANA (200 mg l-1), GA3 (100 mg l-1), GA3 + CuSO4 (100 mg l-1 c/u), CuSO4 (100 mg l-1) y control sin tratar. A los 0, 5 y 10 días post-aplicación se colectaron las flores y se cuantificó en microscopio con fluorescencia el crecimiento del tubo polínico. En campo se seleccionaron 30 árboles y se les aplicaron cinco tratamientos: una y dos aplicaciones de CuSO4 (100 mg l-1), una y dos de GA3 (100 mg l-1) y control. Todos los productos aplicados en el medio de cultivo inhibieron la germinación de polen in vitro y en flores individuales, el crecimiento del tubo polínico con respecto al control. A los 10 días de realizadas las aplicaciones, en ninguno de los tratamientos el avance del tubo polínico superó el 30% de la longitud del estilo y el GA3 (100 mg l-1) impidió su avance más allá del estigma. De los tratamientos a planta entera, el único que resultó eficiente fue la doble aplicación de GA3 que redujo de nueve a siete el número de semillas por fruto en relación al control.

En 2008 y 2009 se realizaron estudios en cuatro viñedos de la variedad Tannat injertada sobre SO4. Fueron conducidos en espaldera e implantados sobre suelos similares, en tres regiones climáticas diferentes. La información climática se originó en estaciones meteorológicas con normas OMM. En cada viñedo se registró el rendimiento por planta, la cantidad de racimos y su peso, el de madera de poda, la superficie foliar, el potencial hídrico de base y otros índices de respuesta. Se analizó la composición mayoritaria (azúcares, acidez total y pH), el potencial polifenólico, los ácidos orgánicos y el peso de la baya. Se utilizó el paquete estadístico INFOSTAT 2009 para realizar análisis de varianza, correlaciones de Pearson y análisis discriminante. Los índices climáticos que tuvieron mayor peso en la discriminación de los viñedos de las distintas zonas fueron el balance de agua y GD10 en maduración, y las lluvias en crecimiento vegetativo. La respuesta de la planta permitió discriminar los viñedos independientemente del año, de forma consistente con el clima. La Superficie Foliar Expuesta potencial y la duración de la maduración fueron los índices de mayor peso, seguidos por el ψ y el rendimiento de uva. En la composición de la uva se destacaron las diferencias en el potencial total en antocianos, los contenidos de azúcares, su acumulación diaria, y la composición ácida. Se concluye que la respuesta de la planta y la composición de la uva fueron fuertemente influenciadas por la oferta hídrica y las condiciones térmicas durante la maduración.

Authors: Gravina Virginia , de Hegedus Pedro
Published: March 2021

Este artículo presenta los resultados de una investigación cuyo objetivo fue utilizar la metodología Q, como herramienta para la evaluación de proyectos de desarrollo rural. La metodología Q es una metodología de investigación que permite al investigador identificar, entender y categorizar percepciones y opiniones de los individuos objeto de estudio, y agruparlas basándose en dichas percepciones. Dicho enfoque aplicado a la evaluación de proyectos, permite captar profundamente las percepciones de los beneficiarios de los mismos. Se trabajó sobre dos proyectos de desarrollo, uno en la provincia de San Luis y otro en la provincia de la Pampa, República Argentina, dirigidos por el INTA, Instituto Nacional de Tecnología Agropecuaria. Para cada proyecto se obtuvieron tres formas diferentes de percibir los resultados, en cuanto a su alcance e impacto en la calidad de vida de los beneficiarios. La metodología probó su efectividad en el logro de una valoración más objetiva y profunda de aspectos que la evaluación tradicional no considera.
Javnozdravstvena perspektiva utjecaja industrijskog onečišćenja na globalno zatopljenje i pojavnost zoonoza

Iako je utjecaj klimatskih promjena na čovjeka i okoliš odavno poznat, manje se važnosti pridaje bolestima koje na epidemiološka vrata ulaze sporednim putem. Zoonoze tako spadaju u skupinu bolesti čiju sve veću pojavnost možemo povezati upravo s klimatskim promjenama i stvaranjem preduvjeta za njihovo širenje.
Pregledom literature utvrđena je sve veća osvještenost glede potencijalnih posljedica moguće pojavnosti zoonoza uzrokovanih zatopljenjem na globalnoj razini, no usprkos tomu u Hrvatskoj takva istraživanja (još) nisu prepoznata.
Pod hipotezom da klimatske promjene i globalno zatopljenje uzrokovano industrijskim onečišćenjem i antropogenim čimbenicima uzrokuju pojavnost zoonoza, nude se rješenja preventivnog karaktera, koja uz pravovremenu detekciju i epidemiološke intervencije nužno ne utječu na pojavnost zoonoza.
Ono što je izglednije i nezanemarivo, jest činjenica da klimatske promjene stvaraju preduvjete za različite puteve prijenosa i širenje zoonoza što bi, ako se negativan trend globalnog zatopljenja nastavi, moglo s vremenom utjecati na njihovu incidenciju i prevalenciju – svakako i u Hrvatskoj – što iz javnozdravstvenog prerasta u globalni okolišnoetički problem.

During the existence of the X-ray method of research, numerous author’s methods of cephalometric examination and analysis using the method of lateral teleroentgenography (methods by Schwarz, Down’s, Steiner, Tweed’s, Harvold, Ricketts, McNamara, Jaraback, Burstone, Bjork, etc.) have been developed. Dentists around the world prefer certain methods, each of which has its advantages and disadvantages. But there is still no single unified methodology for such research and doctors and researchers are constantly trying to improve them and gain new information about their effectiveness. The aim of the study was to establish cephalometric teleroentgenographic parameters and determine their features in Ukrainian young men and women with orthognathic occlusion depending on profiles and facial types according to Schwarz A.M. (hereinafter orthognathic occlusion), divided into separate groups of studies on different profiles and different face types according to Schwarz A.M. (3 groups of different profiles and 3 groups of different face types for people of each sex). Cephalometric teleroentgenographic parameters, which usually do not change during surgery and orthodontic interventions, were studied. Statistical mathematical processing of the research results was performed in the licensed package “Statistica 6.0” using non-parametric methods of evaluation of the obtained results. Numerical reliable and tendencies of differences in certain indicators between groups of young men or women with different profiles or face types have been established. The greatest differences, both in young men and women, were recorded between the indicators determined by the methods of cephalometry by Schwarz A.M. and Bjork A., and the least – by the method of Ricketts R.M. The obtained results testify to the expediency of using the division of young men and women into separate groups by profile and type of face to adhere to the personalized principle in the morphological assessment of cephalometric and gnatometric indicators of lateral teleroentgenography.

The progressive course of diseases of the veins of the lower extremities leads to the development of complications in more than 80% of patients with post-thrombotic disease. Purpose of the work: to study the morphometric features of remodeling of the venous bed of the extremities in experimental trophic ulcer and its correction. A complex of morphological methods was used to examine the veins of the lover limbs of 18 adult male Vietnamese pigs, which were divided into 3 groups. 1 group consisted of 6 intact practically healthy animals, the 2 group – 6 pigs with simulated trophic ulcer, the 3 group – 6 animals with Lidocaine-corrected ulcer. The area of the trophic ulcer was measured. The trophic ulcer was taken together with the surrounding tissues, from which histological micropreparations were made, which determined the diameters of capillary venules, venules, outer and inner diameters of venous vessels, the height of endothelial cells, the diameter of their nuclei, nuclear-cytoplasmic ratios in these cells, volume of damaged endotheliocytes. A correlation analysis was performed between the ulcer area and morphometric parameters. Quantitative values were processed statistically. Strong positive correlations have been established between nuclear-cytoplasmic relation in endothelial cells, the relative volume of damaged endotheliocytes, and the area of the ulcer defect (r=+0,84±0,03), at correction of an ulcer by Lidocaine they weakened a little. It was found that the correction of trophic ulcers with Lidocaine led to a decrease in its area by 25.8%. It is established that the experimental trophic ulcer leads to pronounced remodeling of the venous bed of the lower extremities, which is characterized by significant dilation of venous vessels, venous plethora complicated by hypoxia, atrophic, dystrophic, necrobiotic, infiltrative processes and sclerosis. The use of Lidocaine in experimental trophic ulcer improves the adaptive-compensatory and regenerative processes of the modeled pathology, reduces the relative volume of damaged endothelial cells in the venous vessels of the lower extremity by 18.8% (p<0.001).
