This study was carried out to evaluate the origin, course and terminations of the cardiac veins in Akkaraman sheep and Angora goats. These vessels are the great cardiac, left marginal, middle cardiac, right cardiac and smallest cardiac veins. For this purpose, latex was injected into the jugular vein of eight adult healthy Akkaraman sheep and Angora goats. These veins were dissected. It has been shown that the middle cardiac vein and great cardiac veins coursed with the branches of the coronary arteries and that they were anastomosed with each other. The venous blood from the great cardiac vein and middle cardiac veins emptied into the right atria via the coronary sinus. The venous blood from the interventricular septum was conveyed to the middle cardiac vein and great cardiac veins.

ABSTRACT:The aim of this study is to reveal the morphology of the lyssa in the cat and dog. Eight heads of adult healthy cats and eight heads of dogs of both sexes were used as materials. In the cat the lyssa, yellow coloured, had a helical appearance and its edge facing the oral cavity became sharp; in the dog the lyssa, pinkish white coloured, was more or less J-shaped. The whole body of the cat's lyssa was buried among the intrinsic lingual muscles. In the dog, although aboral, two thirds of the lyssa were squeezed among the intrinsic lingual muscles, its cranial third was placed just under the mucosa to protrude slightly into the oral cavity. In both species, the whole body of the lyssa was determined to have been formed by the nearly adipose tissue in which occasional striated muscles existed. Moreover, in the middle third of the dog's lyssa, dense striated muscle fibres were seen dorsally to the adipose tissue, and we also noticed with interest that the lyssa sheath embracing this part contained few muscle spindle-like structures. It was of interest that in the cat a pyramidal rod encircled by a fine capsule of connective tissue was attached to the ventral edge of the cranial third of the lyssa.

ABSTRACT:The aim of this study was to reveal morphological and morphometrical properties of the sacculus rotundus (SR) and ileum in the Angora rabbit. For this purpose, a total of thirteen adult healthy Angora rabbits of both sexes were used. At the level of the junction of the ileum and SR, the ileum invaginated into the SR by protruding in 9 Angora rabbits, but joined directly the SR in 21. Numerous aggregate lymph follicles located just under the tunica serosa formed outstanding macroscopic polygonal areas on the external surface of the SR. In the inner wall of the SR, irregular projections were seen grossly. The saccorotundocecal orifice was found to be bordered laterally by two folds facing the cecum. These folds enclosed small polygonal spaces with mushroom shaped protrusions. The mean lengths and weights of SR and ileum in male were larger than those in female, and the related values also had statistical significance (P < 0.05). Compared with the ileum, the SR had short and thick villi, had a large amount of crypts and aggregated lymphoid follicles, and had a much thicker wall and much wider lumen. The crescent-like-hollows were detected between the lamina propria and the apical portions of the lymph follicles. The results from this study are thought to shed light on future studies on the digestive system and proper diagnosis of pathological disorders related to it in the Angora rabbit, and to contribute to the present morphological knowledge on the SR and ileum in this species.

Background: Guinea pig is a species belonging to the Caviidae family of the Rodentia order and is frequently used in experimental studies. Biomedical imaging methods are used in the diagnosis and treatment of many diseases in medicine. Among these methods, computed tomography (CT) is one of the most important imaging methods. In this study, it was aimed to perform the three-dimensional (3D) modelling of the CT images, obtained from the humerus and femur in the guinea pigs, via the MIMICS programme, and to make some biometric measurements regarding the bones over these models. Materials and methods: In the present study, 12 male adult guinea pigs were used. The soft tissue on the humerus and femur bones of the guinea pigs was removed. After this procedure, CT images at a 0.5 mm-thickness were obtained from the animals. The images were recorded in DICOM format. Then, the reconstruction process was performed from the images by using the 3D modelling programme MIMICS ® 13.1. On the 3D model of the humerus and femur (right-left), volumes, surface areas and lengths as well as other biometric parameters were measured separately, and the values were recorded. In addition, measurements of the bones were made with the help of a digital calliper. Results: Among the parameters obtained from 3D models, a statistical difference was observed between the right and left cortical thicknesses of the femur from the measurements of calliper and the right and left humerus volumes (p < 0.05); whereas, no statistical difference was found in other parameters of both measurements (p > 0.05). Conclusions: It can be stated that CT and 3D modelling can be used for the measurement of some parameters in the long bones of the guinea pigs.

ABSTRACT. This study was carried out to describe the arterial supply of Meckel's diverticulum (MD) in geese, using 36 adult healthy geese of both sexes, 50 to 52 weeks of age. The arterial supply of MD was classified into three types, In the first type, MD was supplied by a very distinct branch from the cranial mesenteric artery in 21 geese. In the second type, it was supplied by one terminal branch from the cranial mesenteric artery in 9 geese. In the third type, it was supplied both by one branch from the jejunal artery and by terminal branch from the cranial mesenteric artery in 6 geese. Based on the these types, we found significant differences (p≤0.01) in the length of MD between type I and II. The blood supply of the third type was observed more frequently in the male than in the female. Results from this study may contribute to the anatomical knowledge of arterial supply of MD in the geese. KEY WORDS: blood supply, Meckel's diverticulum, goose.
