“…В процессе изучения артериального русла сердца сельскохозяйственных, домашних плотоядных и пушных животных мы установили, что вышеописанная стандартизация не является универсальной. Вариативность ветвления венечных артерий сердца обуславливает доминирование одной артерии над другой при левовенечном или правовенечном типах кровоснабжения [7,8]. Та-ким образом, при левовенечном типе правая коронарная артерия слабо развита и васкуляризирует небольшой участок сердца, а может совсем отсутствовать.…”

“…Поэтому предотвращение возникновения таких симптомов, а также повышение продуктивности зависит от сочетанного применения йода и селена у сельскохозяйственных животных, содержащихся в хозяйствах, находящихся в биогеохимических провинциях [9]. Изучение динамики показателей крови при различных физиологических и патологических состояниях дает возможность оценить клинический статус животного [1,5,8]. Анализ биохимических параметров крови животных позволяет судить о состоянии углеводного, белкового и липидного обменов [2,3,10].…”

The variability of branching of the coronary arteries of the heart determines the dominance of one artery over the other in the left or right coronary types of blood supply. Thus, in the left coronary type, the right coronary artery is poorly developed and vascularizes a small area of the heart, or may be completely absent. The same phenomenon, respectively, can be observed in the right-handed type with the left coronary artery. The German Shepherd is a typical representative of the leftcoronary type of blood supply to the heart, like all other representatives of its species. The aim of our study is to study the vascularization of the left half of the German Shepherd heart. To study the vascular bed of the German Shepherd heart, ten corpses of dogs of this breed were obtained at the age of two to three years after forced euthanasia. The cadaveric material was delivered from private clinics in St. Petersburg to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. The vascular bed of the heart of a German Shepherd was investigated by applying such methods as fine anatomical preparation with filling the vascular bed with latex, as well as corrosion treatment of the obtained material. As a result of the study, it was found that the source of vascularization of the left half of the heart is the left coronary artery and its main arteries, including the paraconal, subsinus, circumferential, left interventricular and left diagonal arteries. The subsinusoid artery is a branch of the left coronary artery, while the right coronary artery does not reach the region of the subsinus sulcus. The interventricular septum of the heart in a German Shepherd is completely vascularized by branches of the left coronary artery. The main artery in this case is the left interventricular artery. The results obtained confirm that the presence of a left-coronary type of blood supply to the heart in an animal does not determine that the region of the subsinus sulcus will be vascularized by the branches of the right coronary artery.

Nasua nasua is a representative of the forests of South America, and is also kept as a zoo animal. The animals have a pronounced mobile and long nose, a fluffy long tail, as a means of signaling; strong claws on the pectoral limbs, which serve not only to move through trees, but also to get food. Currently, there are isolated works on the morphology of the abdominal aorta of this type, but no features of the morphology of the heart have been found, which was the purpose of our study. The material was preserved in a 10% formalin solution of the heart, taken in different years from sexually mature noses received from the Irkutsk Zoo Gallery and the Siberian Zoo of Irkutsk. Classical methods of morphological research were used in the work: fine dissection, morphometry of the heart and its structures, description, sketches and photographing. According to the results of the studies, it was found that the average value of the absolute mass of the heart was 18.2 ± 0.33 g, has an ellipsoid shape, and the ratio of the thickness of the ventricles is at the level of 1:2.8. The internal structure of the right atrium is built of five scallop muscles of the 1st order and nine of the 2nd order, and four scallop muscles of the 1st order and eight of the second order participate in the relief of the left atrium. The shape of the auricle at the right atrium of the heart is 1.5 times greater than the value of the left atrium. In the left ventricle of the heart there are three papillary muscles (cranial and two caudal) with 21-24 tendon strings, and in the right ventricle there are six papillary muscles that carry up to 31 tendon strings on their surface. The septomarginal trabecula connects the parietal pedicle of the accessory and the base of the large papillary muscle.
