Ground squirrel is the only representative of its genus in our country. As
experimental animal is used in microbiology, parasitology, immunology and
pharmacology. The aim of this study was to examine a part of ground squirrel
cardiovascular system and thus help better understanding of anatomy of the
body of this specific animal as well as to contribute to comparative anatomy.
The studies were perfomed on six ground squirrels, both sexes, weight between
200- 300 g. In order to obtain the arterial vascularization of the kidney,
contrast mass gelatin stained with painting tempera was injected into the
abdominal aorta after bleeding out. After the injection, blood vessels were
prepared and photographed. Corosive preparations of the vein blood vessels of
the kidneys were obtained by injection of Byocril into the right azygos vein
after bleeding out. After injection, the preparations were placed into 5%
NaOH for 96 hours or 10% NaOH for 48 hours. After that the preparations were
rinsed with hot water and photographed. A. renalis dextra arises from the
lateral wall of the abdominal aorta, 3-4 mm caudal to A. mesenterica
cranialis. In most cases, this vessel divides into two or three branches
before entering the hilus of the right kidney. A. renalis sinistra arises
from the lateral wall of the abdominal aorta, 7-9 mm caudal to the right
renal artery. Often, instead of one left renal artery, there are two, rarely
three. Based on the results of our study, we concluded that in ground
squirrel there is one A. renalis dextra and often two, rarely three Aa.
renales sinistrae. In renal venous vascularization, both right and left renal
vein are involved. Before entering the kidney, both of them divide into
cranial and caudal branch, undergoing renal hilus, enter the renal sinus and
continues to branch out into smaller branches.
