The European bison belongs to endangered species. Its restitution requires a complete knowledge of the structure and function of its genital organs. The aim of this study was a histological and morphometric examination of the uterus of immature and adult females. Material for the study came from 55 females living in the Białowieża Forest. According to the Polish law, the post mortem use of tissues does not require an approval from an ethics committee. The animals were divided into 2 groups: group I included 36 prepubertal females aged from 2 months to 1.5 years, while group II consisted of 19 sexually mature females aged 2 to 20 years. The samples were stained with haematoxylin and eosin (H&E). Histological and morphometric examinations included measurements of the height of the epithelium, thickness of the endometrium, thickness of the myometrium, thickness of the inner and outer muscular layers, and thickness of the perimetrium. The results were analyzed using the Statistica 12.0™ software. Statistically significant differences were found between the two groups in all morphometric parameters examined. The results revealed a high degree of similarity of the histological structure of the uterus between European bison and domestic cattle.

Materiał do badań stanowiły zwłoki dorosłych osobników, obu płci, w różnym wieku. Przebadano serca: 40 kotów domowych krótkowłosych (Felis silvestris f. catus), 50 norek amerykańskich (Neovison vison) i 23 nornic rudych (Myodes glareolus). Przeprowadzono preparację i morfometrię wyizolowanych serc. Określono: masę ciała zwierzęcia (BW), masę serca (HW), wysokość serca (H) i szerokość serca (W). Uzyskane dane posłużyły do wyliczenia udziału procentowego masy serca w stosunku do masy ciała (I1 ). Różnicę pomiędzy populacją samców i samic dla poszczególnych parametrów określano za pomocą testu NIR Fishera (w odniesieniu do kotów oraz norek), a także za pomocą testu U Manna-Whitneya (w odniesieniu do nornic rudych) przy poziomie istotności p≤0,05. U wszystkich osobników wysokość serca była większa od szerokości. Średnia wartość HW wyniosła 19,08 g dla kota domowego krótkowłosego; norki amerykańskiej 13,05 g; nornicy rudej 0,13 g. Natomiast średnia wartość I1 wyniosła: 0,59% dla kota domowego krótkowłosego; norki amerykańskiej 0,66%; nornicy rudej 0,70%.

Background: Coronary vessels have been widely studied in many species of domestic and wild mammals. However, there are no available literature reports describing the morphology and morphometry of the coronary ostia of the European bison (Bison bonasus). The aim of this study was to measure the area of the coronary ostia and assess their localisation in the coronary sinuses of the aortic root in the European bison. Materials and methods: The study material comprised 27 hearts from European bison of both sexes (16 males and 11 females), from 3 months to 26 years old, inhabiting the Bialowieza Forest (Bialowieza National Park, Poland). The animals were divided into two age groups: ≤ 5 years (group I) and > 5 years (group II). Results: In all the studied European bison, the aortic valve consisted of three semilunar leaflets, left, right and septal. The ostia of both coronary arteries were located beneath the sinotubular junction. The dimensions of the left coronary ostium were larger than those of the right coronary ostium. They were longer by on average 4.5 mm (95% confidence interval [CI] 3.5–5.6 mm), they were wider by on average 1.6 mm (95% CI 1.0–2.2 mm) and they had a larger area by on average 31.6 mm² (95% CI 22.7–40.5 mm²). This was evident both in young and in adult bison. After adjusting for age, there were no differences in the ostia dimensions between males and females. There were no differences in the structure of the left and right coronary arteries in nine animals. In the remaining 18 animals, there were variations in the morphology of the coronary ostia or additional ostia. Conclusions: Because of the anatomical similarity between the European bison and other ruminants, the results of this study can be applied to the other species including endangered ones.
