Öğe The architecture of the lymph nodes in the abdominal and thoracic cavities of wild boar(Agricultural Research Communication Centre, 2019) Bozkurt, Yesim Akaydin; Ates, Sevinc; Kozlu, Tolunay; Basak, FeyzaThe distrubition of lymph nodes located in the abdominal and thoracic cavities of ten wild boars, and their structure were determined anatomically, histologically and immunohistochemically, to be the first detailed investigation on the wild boar. Though general localization and distribution were similar, the number of lymph nodes showed small differences from those of domestic pig. Histological investigations did not reveal a significant hilus. Besides, T lymphocytes with anti-CD3, CD4, CD8, B lymphocytes with anti-CD79a, macrophages with anti-macrophage monoclonal antibodies, and follicular dendritic cells using anti-S100 polyclonal antibody and their distrubution in the lymph nodes were detected. Many CD3 positive T lymphocytes were observed in the germinal center of the lymph follicles, in the cortical area and in the medulla. CD8 positive T lymphocytes were few, and CD4 positive T lymphocytes were not seen. CD79 positive cells were scanty.Öğe Comparative macro anatomy of the heart valves of the New Zealand rabbit and Guinea pig(Ankara Univ Press, 2010) Ates, Sevinc; Cakir, AhmetIn this study, it was observed that comparative macro anatomy of the heart valves of the New Zealand rabbits and Guinea pigs. Also, it was intended that need of information about this topic was supplied. For this purpose, morphology of the heart valves on 10 male New Zealand rabbits and 10 male Guinea pigs were investigated. The findings were obtained through examining the materials fixed in the 10% formol solution by using Olympus MIX dissection microscope. Mann-Whitney U analysis method was applied to numerical data. It was determined that tricuspidal valve was composed of three cusps in the 7 hearts of rabbits and 4 hearts of the Guinea pigs, and it was composed of two cusps in the other hearts observed. Papillary muscles were determined on the septal walls of right ventricles of the hearts. The anterior papillary muscle was observed to be a single one, and the septal papillary muscle was also a single muscle except the heart of one rabbit. It was determined that the number of posterior papillary muscle had individual differences in both rabbits and guinea pigs. It was observed that the bicuspidal valve was composed of two cusps in all the examined animals. Two papillary muscles which were located on the outer wall of left ventricle were seen. They were determined to possess several small heads. On both ventricles, the tendinous chords that extend between the papillary muscles and leaflets of the atrioventricular valves were seen. The investigations on the hearts of the rabbits and guinea pigs exposed that separation of leaflets of valva atrioventricularis dextra and valva atrioventricularis sinistra was not clear. It was observed that valva trunci pulmonalis and valva aortae comprised three semilunar valvulas in all the materials examined.Öğe The effect of the daylight length on, mass and vascularization of the quail (Coturnix coturnix japonica): an experimental study(Agricultural Research Communication Centre, 2016) Atalgin, Sukru Hakan; Kurtul, Ibrahim; Karagoz, Yalcin; Ates, SevincA number of 24 Japanese quails were divided into two groups in order to observe changes in vascularization and weight of the testes during the reproductive and quiescent periods. Group1 was exposed to a long photoperiod of (Light, Dark) 20hL:4hD (20 hour Light:4hour Light) at 18-24 degrees C while the Group 2 received a short photoperiod of 7hL:17hD at 8-12 degrees C. The blood vessels were filled with colored latex for examination. The results revealed that each testis was mostly nourished by a single testicular artery which was arising solely from the descending aorta. The simple nature of the vessels in the quiescent period became very complex as the testes enlarged in the reproductive stage. Weights of the testes between the groups indicated the fact that the left testis was significantly larger during the reproductive and quiescent sexual periods. Consequently, our study showed that long photoperiods and temperatures significantly affect the vascular development of the testes as it is in the reproductive development.Öğe Light and scanning electron microscopic studies on the lingual papillae of 80-day-old wild pig fetal siblings(Tubitak Scientific & Technological Research Council Turkey, 2013) Ates, Sevinc; Bozkurt, Yesim Akaydin; Kozlu, Tolunay; Alan, Aydin; Duzler, AyhanThis study examined the lingual papillae of 80-day-old wild pig fetal siblings through macroscopic and light and scanning electron microscopic observations. The results revealed that fungiform papillae were located on every aspect of the tongue except the ventral surface and the center of the dorsal surface. Conical papillae were present on the dorsal surface of the root of the tongue and marginal papillae were observed on the lateral edges of the tip of the tongue. There were 2 vallate papillae on the dorsal and 2 foliate papillae on the lateral aspects of the root of the tongue. The filiform papillae normally seen in the mature stage were not observed at this stage. Taste buds were identified in all the gustatory papillae examined. On the other hand, taste pores were perceived only in the fungiform papillae. The findings acquired will surely contribute to the literature as an essential base for further related research.Öğe The lumbar dorsal rami of the wild pig: the intermediate branch(Tubitak Scientific & Technological Research Council Turkey, 2014) Kurtul, Ibrahim; Ates, Sevinc; Ozmen, Erdal; Takci, Lutfi; Steinke, HannoThis study has documented the intermediate branch of the dorsal rami of the spinal nerves in the lumbar region of 4 adult wild pigs. The lumbar spinal nerves at the L1-L4 levels left the vertebral canal through the intervertebral foramen. Upon the dissection of the 32 dorsal rami at these levels, 24 were displayed to construct 3 discrete branches while the remaining 8 were observed to form 2 typical branches. The dorsal rami were remarkably short, giving their branches in a fan-like spreading fashion. The lateral branches sent 2 to 3 smaller subbranches to the iliocostalis lumborum muscle, then became the cutaneous nerve. The medial branch innervated the medial component of the intertransversal and the multifidus muscles. The intermediate branch directed into the longissimus lumborum muscle, ramifying there and sending no cutaneous branches to the skin area. Four out of 8 dorsal rami dissected at L5 sent off the intermediate branch with roughly similar patterns and distributions to those seen at L1-L4. The dorsal branches at L6 were relatively longer, advanced dorsally, giving a constant branch, presumably the intermediate branch, to the caudal edge of the longissimus lumborum muscle. It then coursed upward through the subcutaneous fascia as the cutaneous nerve.Öğe A Macroanatomical and Histological Study of the Uropygial Gland in the White Stork (Ciconia cicionia)(Soc Chilena Anatomia, 2011) Kozlu, Tolunay; Bozkurt, Yesim Akaydin; Ates, SevincThe present study was aimed at the macroanatomical and histological investigation and the demonstration of the structural characteristics of the uropygial gland in the white stork. The uropygial gland of two adult male white storks constituted the material of the study. It was determined that the gland was situated subcutaneously in between the caudal aspect of the lumbosacral bone and the first coccygeal vertebrae. The gland was composed of two lobes, which displayed an oval appearance when viewed from above and resembled a water drop when observed medially. Tuft of feathers were present on the caudal margin of each lobe. The present study revealed that the uropygial gland of the white stork is a simple tubular gland, which discharges its secretion into the lumen by a holocrine mode. Each lobe, possessed centrally located large cavities and a main excretory duct and displayed the presence of externally situated peripheral tubules and interiorly situated central tubules. These secretory tubules, which composed the parenchyma, were separated by connective tissue septa referred to as trabeculae, and released their secretion into a centrally located lumen. The wall of the secretory tubules was comprised of four layers, referred to as the germinative, intermediary, secretory and degenerative layers. The silver-staining procedure demonstrated that the stroma of the uropygial gland did not contain reticulum fibres. The anatomy and histology of the gland has been examined in few avian species. Up to date, this study is the first to describe the histological and anatomical peculiarities of the uropygial gland in white stork. The results acquired hereby will surely contribute to further studies to be conducted on the related area.Öğe Mineralization in the syrinx and caudal tracheal rings in the ostrich(Agricultural Research Communication Centre, 2018) Atalgin, Sukru Hakan; Ates, Sevinc; Kurtul, Ibrahim; Terzi, HakanThis study documented macroscopic and microscopic features and mineralization of the caudally located tracheal rings and syrinx in two ostrich (struthio camelus) having three years of age. The syrinx and trachea of the birds were stained in toto with alcian blue and alizarin red for cartilage and mineralization. Observations on the syrinx and trachea, measurements and photography were performed under stereo-microscopy. They were stained grossly using alizarin red and alcian blue to visualize mineralization and histologically by hemotoxylin and eosin (H&E) to detect ossification areas, if any. Results revealed incomplete tracheal rings located caudally in-between the intact ones. Alizarin red and alcian blue staining displayed mineralized regions grossly. Histological slides by H&E staining showed no ossification. Overall results proposed that alizarin red and alcian blue double staining is a good toll to determine mineralization which is calcium accumulation in the tissue before the formation of bone cells.Öğe Morphologic Features of the Interdigital Sinus of the Tuj Sheep(Kafkas Univ, Veteriner Fakultesi Dergisi, 2010) Aslan, Kadir; Kurtul, Ibrahim; Nazli, Muemtaz; Ates, SevincThis research, for the first time, documented the interdigital sinuses and their glandular structures of the fore-and hindfeet of the 10 Tuj sheep (5 male and 5 female) at gross and subgross and light microscopic levels. They were noted in all feet as peculiar tubular invaginations in-between the proximal and middle interdigital joints. The shape of the interdigital sinus resembles that of the pipe, composing of a narrow and long neck and a blind sac. The vascularization was through the 3rd and 4th palmar and dorsal digital arteries at the forefeet, and the 3rd and 4th plantar digital arteries at the hindfeet. The sinus was encircled with a thick capsule connected to the skin and the neighbor tissues through the connective tissue. On transversal section, there were numerous tenuous hairs clearly seen grossly on the section surface. Parenchyma and stroma units were observed in the interdigital gland. There were also hair follicles, sebaceous and sweat glands, muscle tissue and lymph follicles in the layer of the connective tissue. In this study, the morphological features of the interdigital sinuses and the glands that they contain was the first reported in the Tuj sheep. They were active in all feet, were supplied by different digital arteries and thus, it was supposed that the glands were very active on secretion.Öğe Morphological and morphometric features of knee joint in wild boar (Sus scrofa)(Wiley, 2021) Dogan, Ishak; Ates, Sevinc; Erdem, Baran; Takci, LutfiIn the study, it was aimed to reveal the structure of the knee joint anatomically and morphometrically in the wild pig known as the ancestor of the domestic pig. In the study, the left and right knee joints of mature 10 wild boars were used as material. For this purpose, the materials were fixed with 10% formaldehyde solution. Macroanatomical and morphometrical examinations of bones, menisci and ligaments involved in joint formation were performed after fixation. Trochlea and condyles of femur were examined, and various measurements were made. Trochlear labia were found to be the same size, and the condyles did not show a significant difference in size. The shape of lateral condyle of the tibia was trapezoid, and the shape of medial condyle was triangular. Moreover, the lateral intercondylar tubercule was higher according to the medial one. The presence of a shallow groove on the tibial tuberosity was detected. It was found that the width difference between apex and base was more pronounced on the anterior and lateral surface of the patella. Joint surface of the fibula was found to be flat in all materials. The menisci were 'C' shape, but the medial meniscus is more convex than the lateral one. It was observed that the outer edges were thick, while the inner edges were thin. Ligaments of the knee joint were well developed. When the findings of the study were compared with the literature, domestication seemed to have no significant effect in terms of the morphologic properties of the knee joint of wild boar.Öğe Morphology of septomarginal trabeculae in Hatay mountain gazelle (Gazella gazella)(Wiley, 2022) Erdem, Baran; Tutar, Tolga; Takci, Lutfi; Bozkurt, Yesim Akaydin; Ates, SevincThis study was conducted to reveal the anatomical and histological features of left and right septomarginal trabeculae in the heart of the Hatay mountain gazelle. In the study, two female and two male adult Hatay mountain gazelle hearts were used. For this purpose, the materials detected in 10% formaldehyde solution were stained with Crossman's modified triple staining technique and examined under a light microscope after anatomical examinations and measurements were made. The presence of trabeculae in both ventricles was demonstrated. While the number of septomarginal trabeculae was 1 in each of the samples in the right ventricle, it was determined that it was 2 in each of three hearts and 3 in one heart in the left ventricle. It was observed that the right trabeculae were unbranched and fleshy, while the left trabeculae were filamentous and mostly branched. The lengths and thicknesses of the right trabeculae were measured 12-17 mm and 3-4 mm and the lengths and thicknesses of the left trabeculae were measured 6-15 mm and 0.5-1 mm. In the histological examination of both trabeculae, connective tissue, Purkinje fibres and blood vessels were observed, in addition, it was detected that the right trabeculae had myocardial fibres. Few capillaries were found in the left trabecula, while both more capillaries and blood vessels were found in the right trabeculae.
