A. renalis slepog kučeta (Spalax leucodon)

Abstract

U oblasti eksperimentalne humane i veterinarske medicine, kao i u drugim naučnim disciplinama, sve se više pridaje značaj laboratorijskim životinjama. Na njima se mogu pratiti funkcije određenih sistema i njihove farmakodinamske manifestacije, koje nastaju zavisno od vrste, puteva i načina unošenja pojedinih supstanci ili bioloških agenasa u organizam ovih životinja. Jedan od značajnih uslova za ovakva ispitivanja predstavlja potpuno poznavanje anatomske građe organizma ovih životinja. To je bio jedan od glavnih razloga, da obradimo deo kardio-vaskularnog sistema slepog kučeta i na taj način damo prilog boljem poznavanju građe tela ove životinje. Za ispitivanje upotrebljeno je 25 slepih kučića. Posle iskrvavljenja životinja, u krvne sudove su ubrizgane različite kontrasne mase, želatin obojen slikarskom temperom ili minijumom. Krvni sudovi su posle toga preparisani i slikani. A. renalis je paran krvni sud. Počinje iz trbušne aorte 3-4 mm kaudalno od A. mesenterica cranialis. Svaka ide prema bubregu svoje strane. Desna bubrežna arterija počinje nešto kranijalnije nego leva. A. renalis dextra je nešto duža od A. renalis sinistra. Ona ukršta V. cava caudalis na njenoj dorzalnoj strani. Pre ulaska u bubreg svaka bubrežna arterija se deli na Ramus dorsalis i Ramus ventralis. Od leve bubrežne arterije, u blizini njene deobe na Ramus dorsalis i Ramus ventralis, odvaja se jedna grana, koja se pruža u kranijalnom pravcu i ulazi u levu nadbubrežnu žlezdu u njenom kaudalnom kraju. Od desne bubrežne arterije, u blizini njenog ulaska u desni bubreg, odvaja se jedna grana za desnu nadbubrežnu žlezdu. Ona se pruža u kranijalnom pravcu i ulazi u desnu nadbubrežnu žlezdu na njenom kaudalnom kraju. Pre njenog ulaska u desnu nadbubrežnu žlezdu od nje se odvaja jedna grana, koja se pruža u kranijalnom pravcu prema dijafragmi i dovodi krv u dijafragmu (A. phrenica caudalis). Kod slepog kučeta A. renalis je paran krvni sud i počinje iz trbušne aorte. Desna bubrežna arterija počinje nešto kranijalnije od leve. Pre ulaska u bubreg svaka bubrežna arterija se deli na Ramus dorsalis i Ramus ventralis.

The experimental human and veterinary medicines, as well as other scientific disciplines, are turning more and more to laboratory animals. These are suitable for monitoring the functions of certain systems and their pharmacodynamic manifestations, which occur depending on the species, route and manner of administration of certain substances or biological agents in the organisms of those animals. One of the important prerequisites for such investigations is a thorough knowledge of the anatomic structure of the given organism of such animals. This was one of the main reasons why we undertook to investigate the cardio-vascular system of the molle rat contributing in that way to a better understanding of the body structure of this animal. The investigation was performed on 25 molle rats. After bleeding out, various contrast agents were administered, such as gelatin stained with painting tempera or minium. After this the blood vessels were mounted and photographed. A. renalis is a paired vessel arising from abdominal aorta 3-4 mm caudally from A. mesenterica cranialis. Each of the two renal arteries courses towards kidney at its side. Right renal artery arises slightly more cranially than the left one. A. renalis dextra is also slightly longer than A. renalis sinistra. It crosses V. cava caudalis dorsally. Each renal artery divides into Ramus dorsalis and Ramus ventralis and then penetrates kidney as mentioned. From A. renalis sinistra, close to its division into Ramus dorsalis and Ramus ventralis, one branch emerges, runs cranially and enters left adrenal gland at its caudal end. From A. renalis dextra, close to its enter to right kidney, one branch for right adrenal gland arises. It courses cranially and enters right adrenal gland at its caudal end. Before its enter into right adrenal gland, out of it one branch arises, courses cranially towards diaphragm and supplies the diaphragm with blood (A. phrenica caudalis). In molle rat, A. renalis is a paired vessel arising from abdominal aorta. A. renalis dextra emerges slightly more cranially from the left one. Before its penetration into kidney each renal artery divides into Ramus dorsalis and Ramus ventralis.
