The circulatory system is the most important vital system of the animal organism. Its morphological changes may lead to pathological and functional disorders in various organs and systems. For the normal development of a growing organism, the state of the vascular system in early postnatal ontogenesis is of particular importance. The research goal was to study the features of the morphology of the circulatory system in newborn marals since this issue remains practically unstudied. The study was carried out on total organ complexes from 8 marals at the age from birth to 14 days. The methods of material fixation in formalin, preparation, injection of vessels with polyurethane assembly foam and production of corrosive preparations were used. The main arterial lines and the parietal and visceral branches extending from them as well as the veins that form basins of the cranial and caudal vena cava and the portal system of the liver were studied. There is variability in the topography and branching of the vessels. Similar patterns of vascular architectonics in newborn marals with those in other ruminants were noted. A positive correlation was found between the linear parameters of large vessels and the occipital-coccygeal length of the body as well as between the vessel diameter and the body weight. Active processes of proliferation of connective tissue are observed in the Bottalo's and Arantius' (venous) ducts, in the umbilical arteries and in the vein. The conductivity of the venous duct of the liver lasts about two weeks from the moment of birth. The obtained data on the circulatory system of newborn marals are sufficiently new, which is a significant addition to the available information in the field of angiology in ruminants of early postnatal development as well as in the comparative-specific aspect. | Кровеносная система является важнейшей жизнеобеспечивающей системой животного организма. Её морфологические изменения могут привести к патологическим и функциональным расстройствам в различных органах и системах. Для нормального развития растущего организма особое значение имеет состояние сосудистой системы в раннем постнатальном онтогенезе. Цель исследования - изучение особенностей морфологии кровеносной системы у новорожденных маралов, поскольку данный вопрос остается практически не изученным. Исследование проводилось на тотальных органных комплексах от 8 маралов в возрасте от рождения до 14 дней. Были использованы методы фиксации материала в формалине, препарирование, инъекция сосудов полиуретановой монтажной массой, изготовление коррозионных препаратов. В работе изучены основные артериальные магистрали и отходящие от них париетальные и висцеральные ветвления, а также вены, формирующие бассейны краниальной и каудальной полых вен, портальная система печени. Наблюдается вариабильность в топографии и ветвлении сосудов. Отмечены сходные закономерности архитектоники сосудов у новорожденных маралов с таковой у других жвачных животных. Установлена положительная корреляция между линейными показателями крупных сосудов и затылочно-копчиковой длиной тела, а также между диаметром сосудов и весом тела. Наблюдаются активные процессы разрастания соединительной ткани в Боталловом и Аранциевом (венозном) протоках, в пупочных артериях и вене. Проводимость венозного протока печени сохраняется около двух недель с момента рождения. Полученные данные по кровеносной системе новорожденных маралов достаточно новые, что является существенным дополнением к имеющимся сведениям в области ангиологии у жвачных животных раннего постнатального развития, а также в сравнительно-видовом аспекте.

Maral breeding is a dynamically developing industry of the Altai Region and the Republic of Altai. The knowledge of the morphology of the organism of the maral is important when carrying out a number of herd management and veterinary measures in maral breeding. The visual organ and its blood supply play one of the most important roles in the relationship of marals with the environment. By using the generally accepted and original morphological methods, the sources of blood supply and venous outflow tracts of the visual organ in marals were studied. It has been determined that the main sources of eye vascularization are the branches of the external carotid, superficial temporal and maxillary arteries. When approaching the eye and accessory organs, the arterial branches form complex reticular and arcuate anastomoses. There is a large polymorphism of arterial branching. There are described the ways of venous outflow of blood from the visual organ in the maral. The terminal veins of the organ have a complex architectonics of branching and interactions that ensure the plasticity of hemodynamics. The dorsal orbital and horn veins form an anastomosis between themselves which increases the capacity of the venous outflow from the horns. Venous blood is drained into the main vascular collectors: the basilar sinuses, the internal maxillary and jugular superficial veins. Of the deep veins, triconfluent veins are more common. Most of the veins in their course repeat the topographic position of the arteries. In old animals, age-related changes in the vessels are observed: tortuosity of the course and local expansion of the veins, desolation of microcirculatory vessels. The data obtained supplement the angiology data on animal visual organs in a comparative and species related aspect and may be used in the development of methods for treating the visual organ in marals. | Мараловодство является динамично развивающейся отраслью Алтайского края и Республики Алтай. Знание морфологии организма маралов имеет важное значение при проведении ряда зоотехнических и ветеринарных мероприятий в мараловодстве. Орган зрения и его кровоснабжение выполняют одну из важнейших ролей во взаимоотношении маралов с окружающей средой. С помощью общепринятых и оригинальных морфологических методик изучены источники кровоснабжения и венозные пути оттока органа зрения у маралов. Установлено, что основными источниками васкуляризации глаза являются ветви наружной сонной, поверхностной височной и верхнечелюстной артерий. При подходе к глазу и вспомогательным органам артериальные ветви образуют сложные сетевидные и дугообразные анастомозы. Наблюдается большой полиморфизм ветвления артерий. Описаны пути венозного оттока крови от органа зрения у марала. Терминальные вены органа имеют сложную архитектонику ветвления и взаимодействия, обеспечивающие пластичность гемодинамики. Дорсальная глазничная и роговые вены между собой образуют анастомоз, что увеличивает емкость венозного оттока от рогов. Венозная кровь отводится в основные сосудистые коллекторы: базилярные синусы, внутреннюю челюстную и яремную поверхностную вены. Среди глубоких вен чаще встречается триконфлюэнтные вены. Большинство вен по своему ходу повторяют топографическое положение артерий. У старых животных наблюдаются возрастные изменения в сосудах: извилистость хода и локальное расширение вен, запустевание микрососудов. Полученные данные дополняют сведения по ангиологии органа зрения у животных в сравнительно-видовом аспекте и могут быть использованы при разработке методов лечения органа зрения у маралов.

Breed of sheep Dorper has many advantages: animals are easy going about feeding and keeping, they have a high rate of weight gain and their fertility exceeds 100%. The main direction of breeding sheep of this breed is meat sheep. The main source of mutton is the pelvic limbs. During the research studied were the features of running and branching of the arteries of the femoral region of Dorper sheep, in order to establish the syntopic and morphometric characteristics of blood supply to this area. The study has found that the main source of blood supply to the pelvic limb in Dorper sheep is the external iliac artery. The latter travels to the entrance into the femoral canal, before diving into which, at the level of the pubic bone, gives off a deep femoral artery and a circumferential deep iliac artery. Deep femoral artery cranially gives off epigastric-pudendal trunk, and caudally - medial circumferential femoral. The epigastric trunk is divided into two branches: the external epigastric artery and the caudal epigastric artery. The circumferential deep iliac artery is divided into two branches, vascularizing lumbar muscles, abdominal wall muscles, the area of the knee fold. Entering the femoral canal, the external iliac artery passes into the femoral artery. The latter gives numerous branches to the muscles, joints and ligamentous apparatus, the skin of this area. | Порода овец дорпер имеет много преимуществ: животные неприхотливость в кормлении и содержании, имеют высокие показатели прироста массы, а плодоносность превышает 100%. Основное направление разведения овец этой породы – мясное овцеводство. Главный источник баранины - тазовые конечности. В ходе исследования изучали особенности хода и ветвления артерий области бедра овец породы дорпер с целью установления синтопических и морфометрических характеристик кровоснабжения данной области. В результате проведенного исследования установили, что основным источником кровоснабжения тазовой конечности у овец породы дорпер является наружная подвздошная артерия. Последняя следует ко входу в бедренный канал, до погружения в который, на уровне лонной кости отдает глубокую бедренную артерию и окружную глубокую подвздошную артерию. Глубокая бедренная артерия краниально отдает надчревно-срамной ствол, а каудально - медиальную окружную артерию бедра. Надчревно-срамной ствол делится на две ветви: наружную срамную и каудальную надчревную артерии. Окружная глубокая подвздошная артерия делится на две ветви, васкуляризирующие поясничные мышц, мышцы брюшной стенки, область коленной складки. Вступая в бедренный канал, наружная подвздошная артерия переходит в бедренную артерию. Последняя отдает многочисленные ветви для мышц, суставов и связочного аппарата, кожи данной области.

Цель исследований – повышение репродуктивной функции телок голштинской породы. Материалом исследований служили яичники телок голштинской породы в возрасте 16 месяцев, выращенных по разной технологии содержания (стойлово-пастбищная и круглогодовое стойлово-боксовое). Для определения макро-, микро-морфологических показателей исследуемых групп телок был применен комплекс анатомических, гистологических методов исследований. Яичники телок рассекались пополам (через ворота органа) и разрезались на маркированные части размером 1х1 см. Подготовленные образцы обрабатывали по методике Волковой-Елецкого, затем заливали в парафин. Объекты микротомировались на трех четко установленных уровнях, что позволило обеспечить объективность результатов качественного анализа и микрометрии. Гистологические срезы окрашивали гематоксилином эозином, пикрофуксином по Ван-Гизону. Поверхность яичников бугристая с выступающими полостными фолликулами в количестве 3-6 штук в одном яичнике. Форма яичников овальная. Масса правого яичника больше левого, правосторонняя асимметрия. Технология выращивания телок влияет на морфологические показатели яичников у телок. У телок, выращенных в условиях интенсивной технологии, масса и морфометрические параметры яичника меньше, чем у их сверстниц. У телок первой группы среди популяции третичных фолликулов крупные кистообразные фолликулы с очень тонкой стенкой встречаются в 60-80% случаев, а у телок второй группы их 20%, остальные фолликулы сохраняют здоровую структуру. Атретические тела в яичниках телок в основном текально-атретического характера, но у животных, выращенных в условиях интенсивной технологии, они могут принимать кистозную, фиброзную формы (до 40%). В магистральных венах яичника телок, выращенных в условиях интенсивной технологии, выявлены сосудистые расстройства (дилятация, полнокровие). | The purpose of the research is to increase the reproductive function of Holstein heifers. The ovaries of Holstein heifers at the age of 16 months grown by different management methods (stable-pasture and year-round stall-box) were used. Complex anatomical, histological research method has been applied to determine macro-, micro-morphological parameters of the studied groups. Ovaries of heifers were cut in half (through the gates of the organ) and cut into marked pieces of size 1x1 cm Prepared samples were processed by Volkova-Yeletskiy method, and then were embedded in paraffin. Objects were cut with microtome on three strongly predetermined levels, thus ensuring objectivity of the results of the qualitative analysis and micrometry. Histological sections were stained with hematoxylin eosin, picro-fuchsin by Van Gieson. The ovarian surface is bumpy with prominent cavitary follicles in the number of 3-6 pieces in one ovary. The shape of the ovaries is oval. The weight of the right ovary is more than the left one; there is a right-side asymmetry. The heifer management method affects the morphological parameters of the ovaries in heifers. Weight and morphometric parameters of the ovary in heifers grown under intensive technology is less than that of their peers. In heifers of the first group, large cyst-like follicles having very thin wall in population of the tertiary follicles are observed in 60-80% of cases and in heifers of the second group, proportion of such follicles is about 20%, the remaining follicles maintain a healthy structure. Atresial body in the ovaries of heifers have mostly tecale-atresial nature, but in animals grown intensively these structures can have cystic, fibrous shapes up to 40%. Such vascular disorders as dilatatia or plethora were identified in the main veins of the ovary of heifers grown under intensive technologies.

The aim of the present work is to report the catheters design and the surgical method followed for log-term nutrient metabolism studies of the portal drained viscera on a modern (Landrace) and a native (Iberian) breed. It is described a pilot experiment where net flux of glucose was measured to validate the functionality of the catheters design and catheterization method using three Landrace and three Iberian gilts fitted with catheters in carotid artery and portal vein for blood sampling, and ileal vein for para-aminohippuric acid infusion to measure blood flow, and glucose net flux rates. Surgery recovery, catheter patency and results from pilot experiment were excellent. The procedure followed is suitable for pigs and could explain differences in digestive and absorptive capacities between modern and native breeds.

The experiments were carried out on 50 Wistar rats (Rattus norvegicus f. domestica); males and females, weighing 200—architecture of the vessels in the abdominal cavity was studied using corrosion casts prepared with Duracryl Dental and PUR SP (polyurethane material). Our observations focused on the a. mesenterica cranialis et caudalis. The a. mesenterica cranialis originated from the aorta abdominalis cranial to the a. renalis dextra, or as a common trunk with the a. renalis dextra, or after branching off of the a. renalis dextra. The a. colica media, the a. pancreaticoduodenalis caudalis, the a. colica dextra, the aa. jejunales, and the a. ileocecocolica all originated from the a. mesenterica cranialis. We observed a common origin of the a. colica media et dextra, or the a. colica dextra after the emanation of the a. colica media. The third branch was the a.pancreaticoduodenalis caudalis. The Aa. jejunales formed a jejunal arcade, or we observed the presence of a jejunal trunk. The a. mesenterica caudalis originated from: the zone of the aortic bifurcation, the aorta cranial to the branching off of the a. sacralis mediana, caudal to the a. sacralis mediana, or the vessel branched off from the a. iliaca communis dextra.

The purpose of our study was to create a novel rat aorta stent implantation model. Stainless steel bare metal stents (BMS) or paclitaxel-eluting stents (PES) were implanted in male Sprague-Dawley rats (BW 400 ± 20 g). Two and four weeks after stent implantation, the aorta were collected, fixed with 2% glutaraldehyde, and cut into two segments. One segment was used for scanning electron microscopy analysis to evaluate re-endothelialization, and the other segment was used to calculate the neointimal area. At 2 weeks after stenting, the appearance of neointimal hyperplasia was less in the PES group than in the BMS group. At 4 weeks after stenting, no significant difference in neointimal hyperplasia was observed between two groups. On the other hand, the PES group showed more thrombus formation and less re-endothelialization compared to the BMS group. This study demonstrated the ability of a novel rat model of aorta stenting via a common carotid artery to measure the efficacy and safety of commercially available drug-eluting stents.

This paper describes the course and variation in the brain base arteries in fallow deer. The metrical features of the brain base arteries were determined with an image analysis system. The main sources of blood supply to the brain in fallow deer are internal carotid arteries; vertebral arteries rarely participate in blood supply. The brain base arteries in fallow deer show variation both in their course and in the way of descent of particular vessels. The highest variation was observed in the way of the opening of caudal cerebral arteries. The volume of the arterial circle of brain in fallow deer is similar to the volume of the basilar artery. Considering the correlation between specific parameters, it can be concluded that the volume of the basilar artery is highly correlated with the volume of the posterior part of the arterial circle of the brain, i.e., the volume of the caudal communicating arteries.

Boxer are predisposed to subaortic (SAS) and pulmonic stenosis (PS). To decrease the prevalence, pre-breeding cardiologic exams were performed in the last years. In our study the results of 309 pre-breeding exams of boxers presented between 1999 and 2008 were evaluated retrospectively. The overall prevalence of heart murmurs was 26.5 %. A SAS was diagnosed in 25 (8.1 %) and a PS in 10 (3.3 %) dogs. A combination of both defects was found in 7 (2.3 %) Boxers. Animals with a heart murmur of at least grade 3/6 had a significantly higher peak aortic flow velocity (VmaxAo) than animals without or only soft heart murmurs. Over the study period both the frequency of heart murmurs and diagnosis of SAS and PS decreased.

This study was performed to determine the arterial vascularization of stomach in 10 donkey. All materials were filled with latex and dissected. It was detected that stomach was vascularised by a.hepatica, a.gastrica sinistra and a.lienalis, which are branches of a.celiaca. It was determined that a.hepatica vascularized the pars pylorica with its branch named a.gastrica sinistra and vascularised the right side of curvatura ventriculi major of stomach with its branch named a.gastroepiploica dextra. It was observed that a.gastrica sinistra gives the branches named r.parietalis and r.visceralis for the facies parietalis and facies visceralis of stomach. It was also detected that a.lienalis gives aa.gastricae breves to the half left of curvatura ventriculi major. | Bu çalışma, 10 merkepte midenin arterial vaskularizasyonunu belirlemek için yapıldı. Tüm materyaller lateks ile dolduruldu ve diseksiyon yapıldı. Midenin a.celiaca'nın dalları olan a.hepatica, a. gastrica sinistra ve a.lienalis tarafından vaskularize edildiği saptandı. A.hepatica'nın a.gastrica dextra isimli dalı ile midenin pars pylorica kısmını, a. gastroepiploica dextra adındaki dalı ile de midenin curvatura ventriculi major'unun sağ yarımını vaskularize ettiği belirlendi. A. gastrica sinistra'nın midenin facies parietalis ve facies visceralis'i için r. parietalis ve r. visceralis isimli dalları verdiği gözlendi. A. lienalis'in de curvatura ventriculi major'un sol yarımı için aa. gastricae breves'i verdiği tespit edildi.
