Öğe Beç tavuğu (Numida meleagridis) ve Hindi (Meleagridis gallapova) Os hyoideum’u Üzerinde Karşılaştırmalı Makro-Anatomik İncelemeler(Erciyes Üniversitesi, 2015) İlgün, Ramazan; Kuru, Nilgün; Özkan, Zait EnderBu araştırmada Phasinidiae familyasında yer alan beç tavuğu ve aynı familyadaki hindinin os hyoideum’ları karşılaştırmalı olarak incelenmiş ve önemli farklılıklar ortaya konulmuştur. Beç tavuklarında ve hindilerde çift kıkırdaksal olarak bulunan os entoglossum’ların lateral’e yönelmiş yüzlerinin derin birer fossa oluşturmakta olduğu görüldü. Entoglossal kemik basihyoideum’a bağlanarak beç tavuğunda öne doğru sivrilmiş yassı vaziyetteyken, hindilerde daha keskin bir ok ucu şeklinde idi. Beç tavuklarında os hyoideum’un ramus hyoideus’u oluşturan kısa kıkırdakları lateral olarak cranium’a doğru yanlardan basık dışbükey olarak seyretmekte iken hindilerde aynı isimli kollar daha fazla dışbükey olarak lateral’e doğru uzanmakta ve daha uzundu.Öğe Endocrine cells in the gastrointestinal tract of Garra rufa(Veteriner Fakultesi Dergisi, 2010) Kuru, Nilgün; Çinar, Kenan; Şenol, Nurgül; Demirba?, Emel; Diler, DilekThe distribution and relative frequency of endocrine cells in the gastrointestinal tract of the Garra rufa were studied immunohistochemically using the peroxidase anti-peroxidase complex method. The aim was to determine the distribution of specific immunoreactivities in some regions of digestive tract of the Garra rufa against the antisera VIP, substance-P, histamine, glucagon, gastrin, CCK-8, somatostatin and serotonin. The samples were taken from the enlarged areas of after oesophagus, anterior intestine, middle intestine and posterior intestine. The most intensive region of immunoreactive cells were determined as the anterior intestine. Generally, eight types of endocrine cells declined in number from the enlarged areas of after oesophagus to the intestines. These immunoreactive cells were found in the posterior intestine at very low frequencies. As a result of the immunohistochemical studies, all the peptides studied were determined to be localized generally in different distribution within the stomachs of Garra rufa (the enlarged areas of after oesophagus) as well as within their intestines (anterior, middle and posterior intestine). Density of the peptides was concluded to be associated closely with functions in Garra rufa.Öğe Macro-anatomical and Morphometric Investigation of the Tongue and Lingual Papillae in the Guinea fowl (Numida meleagridis)#(2019) İlgün, Ramazan; Kuru, Nilgün; Bölükbaş, Ferhan; Gür, Fatih MehmetThe aim of this study was to investigate the macroanatomy and morphometric of the tongue of theguinea fowl. Six chicks (6-7 weeks), six layer hens (9-13 weeks) and six studs guinea fowl wereused to study and determine the anatomical features of the tongue of the guinea fowl. Papillae of thetongue were examined photos of the general anatomic structures were taken. Morphometry wascalculated by statistical analysis. The tongue was triangular shaped, and consisted of apex, corpus,and radix sections. The papillae linguales caudales were on both sides of the corpus and radixlinguae. Conical papillae were found to be sequentially V shaped at the radix. Thus, in this study,the anatomy and morphometric of the tongue of the guinea fowl tongue were examined in detailsand the similarities and differences between the tongue of the guinea fowl and the tongue of other poultry species were investigated.Öğe Macroanatomic Investigations of the Course and Distribution of the Celiac Artery in the New Zealand Rabbit(Van Yüzüncü Yıl Üniversitesi, 2016) Kuru, NilgünThe course and distrubution of the celiac artery was investigated macroanatomically in the New Zealand rabbits in this study. A number of eight New Zealand rabbits (Oryctolagus cuniculus: Rodentia) (four male, four female) were used in the study. The materials were injected with red colored latex and corrosion casted with mono- polymethymethacrylate (takilon) through the abdominal aorta. It was determined that the celiac artery arose from the ventral surface of the abdominal aorta, and terminated giving off the lienal, left gastric and hepatic arteries. It was observed that the lienal artery originated from the left border of the celiac artery and terminated under the name of the left gastroepiploic artery. It was state that the left gastric artery anastomosed with the right gastric and short gastric arteries. It was indicated the short gastric arteries was determined to stem from the lineal artery in the New Zealand rabbits. In the study, it was also observed that the proper hepatic artery was not to be a branch of the hepatic artery. It was determined that the hepatic artery was the continuation of the celiac artery after leaving the left gastric artery and terminated splitting the right and left branches after giving off the common stem of the right and middle gastric arteries, the side branches to pylorus and lesser omentum and the gastroduodenal artery. The branches and distribution of the celiac artery were found to be not gender dependent.Öğe Seasonal variation in the expression pattern of heat shock protein 70 and 90 in Common carp (Cyprinus carpio) from Karataş Lake, Burdur, Türkiye(Veterinary Research Forum, 09.2023) Kuru, Nilgün; Öztop, Mustafa; Demirbağ, Emel; Ercan, NazlıOrganisms have evolved defense mechanisms to protect themselves from stressful conditions. The expression of heat shock proteins is considered a valid indication of protection from the adverse effects of hostile conditions. In this study, we used immunohistochemistry to investigate the seasonal effects of some abiotic factors on heat shock protein 70 and 90 (HSP70 and HSP90) expression in the liver, gills, and muscle tissues of 24 Common carp (Cyprinus carpio) caught in Karataş Lake (Burdur, Türkiye) using gillnets of various mesh sizes. We also measured some physicochemical parameters on-site at sampling time and took water samples for further analyses of other physicochemical parameters and heavy metals. Immunostaining for HSP90 was stronger than for HSP70 in both liver and gill samples. Liver and gill structures exhibited significant seasonal differences in HSP70 and HSP90 immunoreactivity, and the same was true for immunostaining for HSP70 and HSP90 in muscle samples. Some physicochemical properties seemed to vary considerably between seasons, with Fe, Mn, and Zn levels tending to exhibit changes throughout the seasons. However, these levels were considered acceptable for human health. In conclusion, this study suggests that substantial changes in HSP70 and HSP90 expression may be essential for seasonal adaptation and tolerance. Further research on fish HSPs would greatly contribute to aquaculture, which is essential for meeting food requirements.
