Öğe Determination of sex-related diff erences based on 3D reconstruction of the chinchilla (Chinchilla lanigera) vertebral column from MDCT scans(CZECH ACADEMY AGRICULTURAL SCIENCES, 2017) Ozkadif, S.; Eken, E.; Dayan, M. O.; Besoluk, K.This study was undertaken to obtain and analyse, on the basis of sex, three-dimensional (3D) reconstructions obtained by a 3D computer program from two-dimensional (2D) vertebral column sections taken by multidetector computed tomography (MDCT) images, in the chinchilla. A total of 16 adult chinchillas (Chinchilla lanigera) of both sexes were used. The MDCT images were taken under general anaesthesia, and were then transferred to a personal computer on which 3D reconstructions were carried out using a 3D modelling program (Mimics 13.1). The volume, surface area and vertebral body length of each vertebra (except caudal region) forming the vertebral column were measured from the 3D models created. The ratios (in percentage) of the measurements of each vertebra (except the sacral ones) forming the vertebral column region (cervical part, thoracic part, lumbar part) were determined for statistical analysis. We detected significant differences (P < 0.05) between sexes in all vertebrae forming the vertebral column of the chinchilla with respect to volume, surface area and vertebral body length, except for C6 and L1. This study is the first to carry out 3D reconstructions of data obtained from CT images in the chinchilla and the obtained results contribute to a more detailed understanding of the anatomy of this species. Our strategy may also be useful for the design of experiments exploring the vertebral column in domestic mammals and humans.Öğe A Morphological and Morphometrical Study on the Sacculus Rotundus and İleum of the Angora Rabbit(Czech Academy Agricultural Sciences, 2006) Besoluk, K.; Eken, E.; Sur, E.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.Öğe Morphological studies on lyssa in cats and dogs(CZECH ACADEMY AGRICULTURAL SCIENCES, 2006) Besoluk, K.; Eken, E.; Sur, E.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.Öğe Three-dimensional reconstruction of New Zealand rabbit antebrachium by multidetector computed tomography(SHIRAZ UNIV, 2015) Ozkadif, S.; Eken, E.; Besoluk, K.; Dayan, M. O.The aim of this study was to reveal biometric peculiarities of New Zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3D) reconstruction of multidetector computed tomography (MDCT) images. Under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic MDCT. Biometric measurements of the reconstructed models from high resolution MDCT images were analyzed statistically. Consequently, when biometric measurement values of corresponding bones of antebrachium were compared, it was revealed that there was no statistical significance within both sexes but there were statistically important differences between both sexes in some biometric measurements. It has been suggested that the results from the study can shed light on future studies on the skeletal system and can form a modern point of view to anatomical education.Öğe Three-Dimensional Reconstruction of Stomach and Intestines in New Zealand White Rabbits from Computerized Tomography Images(ISRAEL VETERINARY MEDICAL ASSOC, 2011) Dayan, M. O.; Besoluk, K.The aim of this study was to produce three-dimensional reconstructions of organs of the gastro-intestinal system obtained from computerized tomography images. A total of 16 New Zealand White rabbits were used. Computed tomographic imaging was performed in the prone position in fasted rabbits under general anesthesia using contrast medium administered both orally and rectally. Axial images obtained from computed tomography were stored in DICOM format and transferred to CD. Three-dimensional reconstructions were produced using MIMICS (R) 12.1 computer software. The lengths of stomach, duodenum, jejunum, ileum, cecum, appendix and colon were measured in centimeters after euthanized. The volume and surface area of the organs of the gastro-intestinal system were calculated automatically by the computer software. The jejunum was the longest portion (p<0.05) of the gastrointestinal system. The small and large intestines had the largest surface area (p<0.05) compared to stomach and cecum, while the cecum had the largest volume (p<0.05) compared to stomach, small and large intestines. The surface areas of the stomach, cecum and intestines to the total gastro-intestinal system area were 11%, 39% and 48%, respectively. The volumes of the stomach, cecum, and intestines to the total gastro-intestinal system volume were 17%, 59% and 23%, respectively. In the ventral view of the abdominal cavity the stomach was observed in the cranial abdominal cavity; ileum and colon were determined in the median line of abdominal cavity and cecum filled the rest of the abdominal cavity. In conclusion, the results obtained using this technology as applied in this study may be a key to future investigations and to a new approach to anatomical science.
