Öğe Apoptosis in testicular tissue of rats after vasectomy: evaluation of eNOS, iNOS immunoreactivities and the efects of ozone therapy(2014) Alpcan, Serhan; Başar, Halil; Aydos, Tolga Reşat; Kul, Oğuz; Kısa, Üçler; Başar, Murad MehmetAmaç: Rat testiküler dokusunda vazektomi sonrası serum ve seminal plazma seks hormonları düzeyi yanı sıra endotelyal nitrik oksit sentaz (eNOS) ve indüklenebilir nitrik oksit sentaz (iNOS) ekspresyonu değişiklikleri ve apoptotik indeksi değişikleri ve ozon terapinin (OT) etkisini araştırmak. Gereç ve yöntemler: Yetişkin erkek Wistar sıçanları (n6 her grupta) kullanıldı. Kontrol (G1), 4 hafta (G2) ve 6 hafta (G3) sham operasyonu, sol vazektomi sonrası 4. hafta (G4) ve 6.haftada (G5) orşiektomi, bilateral vazektomi sonrası 4. hafta (G6) ve 6. haftada (G7) orkiektomi, plasebo ikili vazektomi, sol (G8) ve bilateral (G9) vazektomi sonrası 6 hafta ozon terapi sonrası orşiektomi 6 hafta sonra ve 6 hafta OT (G10) sonrası orşiektomi grupları oluşturuldu. Bulgular: G4 ve G5de sol testiste eNOS ve iNOS immünoreaktivitesinde ve apoptotik indekslerde artış varken karşı testiste hiçbir değişiklik gözlenmedi. OT G8in sol testisinde ve 9un her iki testisinde bu parametreleri inhibe ederken, G6 ve G7 artış izlendi. Seks hormon düzeyleri vazektomi ve ozon tedavisi sonrası herhangi bir değişiklik izlenmedi. Sonuç: OT stres koşulları altında yukarıda bahsedilen bazı parametrelere karşı koruyucu olduğu tespit edilirken, sağlıklı koşullarda uygulandığında bazı zararlı etkilere neden olabileceği gözlendi.Öğe Bir kısrakta miks sarkoid olgusu(2006) Kul, Oğuz; Süer, Cenk; Macun, Hasan Ceyhun; Karabacak, AliBu raporda, 8 yaşlı yarım kan İngiliz bir kısrağın ventral abdomen bölgesinde saptanan miks sarkoid olgusu klinik ve patolojik bulguları ile tanımlanmıştır. Tümör, 6x4x3 cm ölçülerinde, yüzeyi ülserli ve kanamalı, kılsız deri ile örtülü deri yüzeyden taşkın diskoid şekilli bir kitleden ibaretti. Histopatolojik incelemede, epidermiste yaygın ülser alanları, hiperplazi, oıtokeratotik hiperkeratoz ve yer yer epitelyal incelmeler dikkati çekti. Nadiren akantozis ve kistik kıl folliküllerine rastlandı. Dermişte yumak şeklinde kıvrımlar oluşturan fibroblast benzeri iğ ve çomak şekilli hücre proliferasyonları görüldü. Farklı sarkoid tiplerine ait klinik ve histopatolojik bulgular gözlenen bu tümöre miks sarkoid tanısı konuldu.Öğe Cellular Immunity-Pathogen Interactions in Infectious Diseases(Hindawi Publishing Corp, 2015) Abubakar, Muhammad; Atmaca, Hasan T.; Zahoor, Muhammad A.; Kul, Oğuz…Öğe Glukozamin kondroitin sülfatın onarılmış tenotomize sıçan aşil tendonları üzerine etkisi(2011) Özer, Hamza; Taşkesen, Anıl; Kul, Oğuz; Selek, Hakan Y.; Turanlı, Sacit; Köse, Serdal KenanAmaç: Bu deneysel hayvan çalışmasında glukozamin kondroitin sülfatın (glcN-CS) sıçan Aşil tendonları üzerindeki etkisi değerlendirildi. Gereç ve yöntemler: Otuz adet 300-350 g ağırlığında Wistar albino türü sıçan rastgele iki gruba ayrıldı. Grup A: Aşil tendonları tenotomize edildi, tamir yapıldı ve glcN-CS ağızdan verildi. Grup B: Aşil tendonları tenotomize edildi ve tamir yapıldı. Bütün sıçanlar pelet yem ile beslendi. Her gruptan beşer sıçan 4, 8. ve 12. haftalarda sakrifiye edildi. Her gruptan üç adet tendon örneğinin gerilme gücü biyomekanik olarak test edildi ve iki örnek de immünohistokimyasal boyama ve hematoksilen ve eozin boyama yapılarak histopatolojik açıdan analiz edildi. Karşı taraf Aşil tendonları da gruplandırıldı ve kontrol olarak analiz edildi (grup C ve D). Bulgular: Histolojik sonuçlarda, grup A’da daha az enflamasyon ve daha düzgün kollajen oluşumu olduğunu görüldü. Biyomekanik testlerde 8. haftada A grubunda istatistiksel olarak anlamlı olmasa da daha yüksek tendon güçleri kayıt edildi (554.84N, p0.078). Glukozamin kondroitin sülfat verilen hayvanlarda tendon gerilim güçleri istatiksel olarak anlamlı bir şekilde yüksek bulundu (50.015.62N, p0.014). Sonuç: Glukozamin kondroitin sülfat sıçanlarda Aşil tendonu iyileşme sonuçlarını geliştirmiştir. Bu sonuç enflamasyonu azaltması ve kollajen sentezini uyarması ile ilişkili olabilir. Her ne kadar glcN-CS sadece osteoartriti bulunan hastalarda semptom ve belirtileri geriletmesi için önerilse de spor yaparken oluşan yumuşak doku yaralanmalarının tedavisi için de tercih edilebilir.Öğe In-vivo efficacy of toltrazuril on experimentally induced Toxoplasma gondii tissue cysts in lambs: A novel strategy for prevention of human exposure to meat-borne toxoplasmosis(Elsevier Sci Ltd, 2013) Kul, Oğuz; Yıldız, Kader; Öcal, Naci; Freyre, Alvaro; Deniz, Abdulkerim; Karahan, Siyami; Terzi, Osman SafaThe aim of the present study was to investigate in vivo efficacy of toltrazuril on Toxoplasma gondii tissue cysts following induction of chronic toxoplasmosis in 4-week-old lambs (n = 27) by inoculation of 1 x 105 T. gondii ME 49 strain oocysts (day 0). Beginning at the 15th day after inoculation, lambs in Group T20 and Group T40 were given toltrazuril orally 2 times, once every week (Baycox 5%, Bayer Animal Health) at a dose of 20 mg/kg and 40 mg/kg, respectively. Positive control (PC) lambs were not given any therapy, and 2 clinically healthy non-infected lambs were used as negative controls (Group NC). Two out of 9 lambs in PC group (oocyst inoculated but non-treated) were killed on toltrazuril treatment days (day 15 and 22) to evaluate the tissue cyst presence in their muscles. On day 90, the remaining 25 lambs were necropsied, and samples from the brain and 11 different muscle groups were collected. The tissues were examined for the presence of tissue cysts by histopathology, immunohistochemistry, nested-PCR and percoll gradient centrifugation. Anti-T. gondii antibodies were screened by IFAT throughout the experiment. The increased T. gondii seropositivity beginning from the 15th day of inoculation remained steady at Day 45 and Day 90 in Groups PC while it was significantly lower at Day 90 in toltrazuril receiving groups. In toltrazuril treated groups, histopathological findings included degenerative changes in the cyst wall, complete macrophage invasion to the cysts, and reduction or removal of the cysts in to to. Four out of 9 lambs (44.4%) in both toltrazuril treated group (Group T20 and T40) did not contain tissue cyst in any examined tissues while all positive control animals had T. gondii tissue cysts at least in one muscle group. The toltrazuril treatment efficacy on the cyst presence was determined as 44.4%. The number of the cysts in the musculature was significantly different between non-treated and toltrazuril treated lambs (X-2 = 6.613; p = 0.037). For the total number of cysts, the positive control lambs had higher number of cysts compared to both toltrazuril treated lambs (T20 and T40) (X-2 = 5.629; p = 0.018 and X-2 = 5.629; p = 0.018, respectively) while there were no differences between Group T20 and Group T40 (X-2 = 0.000; p = 1.000). According to PCR results, the brain and M. semitendinosus were positive in all 7 control lambs while 12 out of 18 lambs were positive in toltrazuril treated lambs. In conclusion, the results are promising as the toltrazuril treated lambs had markedly less parasite counts compared to those of untreated lambs. Further research should be conducted to reveal if toltrazuril treatment in sheep could be used as a strategy to minimize the cyst exposure of humans through consumption of raw or undercooked mutton.

Bu çalışmada; klinik belirti gösteren ya da T. gondii seropozitif bulunan kedilerde uygulanabilecek bronkoalveolar lavaj ve PZR tanı yöntemlerinin geçerliliği sorgulanarak, tanısal önemleri araştırıldı. Ayrıca, seropozitif bulunan kediler arasında sistemik toksoplazmozis görülme sıklığı ile dışkıda ookist varlığı muayene edildi. Çalışma materyalini, 102 kediden alınan kan, uygun olgularda ise bronkoalveolar lavaj, deri ve karaciğer biyopsileri oluşturdu. Bu kapsamda, kan serumlarında Sabin-Feldman boya testi ile T. gondii seropozitif bulunan kediler seçilerek; anestezi altında endotrakeyal kateter yardımıyla bronkoalveolar lavaj örneğinde sitolojik muayene yapıldı. PZR analizinde ise T. gondii B1 geni spesifik primerler ile konvansiyonel-PZR prosedürleri uygulandı. Çalışmada incelenen kedilerde T. gondii seroprevalansı 49/102 (%48.03) olarak belirlendi. Anti-Toxoplasma gondii antikor titreleri açısından incelendiğinde; bunlardan %40.19'unun (41/102) 1/16, %7.84'ünün (8/102) ise 1/64 titrede olduğu ortaya konuldu. Sonuç olarak, seroprevalans %48.03 olmasına rağmen sistemik toksoplazmozis oranının (49 seropozitif kediden biri, %0.98) oldukça düşükgerçekleştiği belirlendiÖğe Koyunlarda toxoplasma gondii doku kistlerinin yaygınlığı ve serolojik sonuçlarla karşılaştırılması(2012) Yıldız, Kader; Kul, Oğuz[Abstract Not Available]Öğe Multivesicular cysts in cattle: Characterisation of unusual hydatid cyst morphology caused by Echinococcus granulosus(Elsevier Science Bv, 2010) Kul, Oğuz; Yıldız, KaderEchinococcus granulosus, the causative agent of cystic echinococcosis, not only often causes unilocular cysts in intermediate hosts, but also in rare cases induces formation of multivesicular cysts which have similar morphology to alveolar cysts. The aim of the present study was to characterise multivesicular and unilocular hydatid cysts in cattle using morphologic and molecular diagnostic tools. Multivesicular cysts were detected in 4 out of 1255 slaughtered cows. Four unilocular cysts were also included in the study to compare with multivesicular cyst morphology. For histopathological evaluation, tissues were fixed in 10% neutral formalin. Following a routine histological tissue-processing procedure, samples were embedded in paraffin blocks and serial sections were cut at a thickness of 4-5 mu m. For polymerase chain reaction (PCR), cyst walls and/or protoscolices recovered from six materials were preserved in 70% alcohol. Histopathologically, severity of calcification, fibrous capsule formation and giant cell layer were similar for multivesicular and unilocular cysts. However, the severity of subcapsular inflammation, inflammatory cell infiltration into adjacent organ parenchyma and eosinophil leucocyte infiltration into the cyst lumen was higher in multivesicular cysts. PCR analyses revealed that all unilocular hydatid cysts as well as two out of four multivesicular cysts were G1 genotype of E. granulosus. Molecular diagnosis of the other two multivesicular structures remained inconclusive as DNAs obtained from paraffin-embedded cyst walls were fragmented to small parts, as short as 100 bp, which were not suitable for PCR analyses. In conclusion, molecular analysis concomitant to histopathological examinations is useful in differential diagnosis of multivesicular echinococcosis. (C) 2010 Elsevier B.V.

AycanNeospora caninum, a protozoan parasite, has been considered as one of the most important etiological agents responsible for abortion in dairy cattle throughout the world since it was first identified in dogs in 1988. In this report, characteristics of neosporosis, detected in a dairy cow ranch having epidemic abortions as high as 18.4%, were described. Blood samples were collected from 25 infertile or aborted dairy cattle, 6 calves born in 2006 and 40 heifers that were born in 2005 and raised in the same ranch. Necropsy was conducted in a 20-day-old Simmental calf that exhibited neurological signs including incoordination, head shaking, hyperextension in forelimbs and hindlimbs and tremor. The seroprevalance in aborted or infertile dairy cattle, heifers, and calves was 60%, 40%, and 33.3%, respectively. The mothers of seropositive two calves including clinically affected calf and its dam were N. caninum seropositive. In immunoperoxidase examinations, N. caninum antigen immunopositivity was observed in the degenerative and necrotic neurons in the brain, cerebellum as well as neurons in dorsal root ganglia of the cervical and thoracic regions of the spinal cord. In the heart, myocytes and Purkinje cells exhibited granular and linear patterns of immunoreactivity. Striated myofibers around the eyeball also showed immunolocalization for N. caninum antigen. Ultrastructurally, tachyzoites with typical apical complex, rhoptries and (double-layered parasitic membrane Were detected in the brain and heart sections. In conclusion, this report described clinical neosporosis for the first time in Turkey with tissue localization of the causative agents. This scientific communication also discusses the possible impact of cattle neosporosis by clinical, serologic and pathologic evidences collected from the Survey of calves born in two successive generations in a ranch.

Macroscopically, the tumorous mass covered the hilus of the left kidney. It was 26 x 22 x 12 cm in size and 3700 g in weight. Metastatic tumorous nodules, 0.5-2.0 cm in diameter, were found on the abdominal side of the diaphragm and in the lungs. Microscopically, numerous large osteoclast-like multinucleated giant cells and spindle-spheroidal-shaped cells were seen. Osteoblastic differentiation and osteoid matrix were noted in a few areas at the periphery of the tumour, near the connective tissue septa. The stroma of the tumour tissue was vascular, oedematous and loose. By immunoperoxidase staining, tumour cells showed immunoreactivity for vimentin but not for keratin and desmin, indicating that the tumour had mesenchymal origin. This is the first report in the literature on a malignant osteoclast-like giant cell turnout arising from a visceral organ in animals.Öğe An outbreak of avian tuberculosis in peafowl (Pavo cristatus) and pheasants (Phasianus colchicus) in a zoological aviary in Turkey(Czech Academy Agricultural Sciences, 2005) Kul, Oğuz; Tunca, Recai; Hazıroğlu, Rıfkı; Diker, K. Serdar; Karahan, SiyamiAvian tuberculosis was diagnosed histopathologically and microbiologically in two pheasants (Phasianus colchicus) and two peafowl (Pavo cristatus) kept in the same aviary. The incidence of avian tuberculosis in the aviary was 6%. Non-mineralized caseogranulomas were present in the liver (3 cases), spleen (3 cases), intestine (2 cases), lung (2 cases), and cloaca (1 case). Granulomas in the lung were present only in peafowl. The presence of granulomas in the lung of both infected peafowl suggests that peafowl were exposed to the agent via the respiratory route rather than the alimentary route. Histopathologic findings were typical of avian tuberculosis, including acid fast bacilli and centrally located caseo-necrosis surrounded by epitheloid macrophages, lymphocytes, and multinucleated giant cells. Mycobacterium avium subsp. avium was isolated from tissue samples of all infected birds.Öğe Patolojik Apoptozis Ve Tanı Yöntemleri(2016) Dinçel, Güngör Çağdaş; Kul, Oğuzİlk kez Kerr ve arkadaşları tarafından 1972 de tanımlanan apoptozis, biyolojik görevlerini tamamlamışyapısal elemanları ya da DNA’sı hasar görmüş hücrelerin, ilişkili olduğu doku ve hücrelere zarar vermeyecek birbiçimde ortadan kaldırılmasını sağlayan, genlerle kontrol altında tutulan ve gerçekleşmesi için enerjiye ihtiyaçduyan programlı hücre ölümüdür.

The present study describes clinical, gross and histopathological findings of PEM following an abrupt change of diet in two ranches housing 2750 dairy and 2300 beef cattle. As a result of severe PEM, 256 cattle died or were slaughtered. Clinical findings included circling, hypersensitivity, excessive salivation, hypermetria, incoordination, blindness and death. The first clinical signs occurred in beef calves (6-8 months old) at a holding facility. Clinical signs of the disorder continued intermittently during the 5-month period in both ranches and were more evident in calves and lactating dairy cows. The affected cattle did not respond to thiamine injections. Clinical signs disappeared gradually following removal of barley malt sprouts from the diet. Although macroscopic lesions were not apparent in the brain tissues of some animals, histopathology typical of PEM was found in most cases: spongiosis in the neuropil and neuronal necrosis, haemorrhage, capillary hyperplasia, fibrinoid degeneration in arterioles, multifocal liquefaction necroses in the grey matter and abundance of gitter cells with vacuolar large cytoplasm. Sulphide in rumen fluid of a clinically affected animal was measured as 1.55 mg/dl, which is considerably higher than that collected from two control cows (mean 0.21 mg/dl). The total sulphur content of the diet containing barley malt sprouts was estimated to be 0.45%, which is also higher than the National Research Council (NRC) maximum tolerable levels. In conclusion, PEM can result from excess barley malt sprout intake because of its higher sulphur content. Clinical signs may occur shortly after the intake of barley malt sprout as outbreaks with a higher number of deaths or as an ongoing periodic condition.Öğe Prophylactic and therapeutic effects of (6)-shogaol on alveolar bone loss in experimental periodontitis(Istanbul Univ Press, Istanbul Univ Rectorate, 2024) Bezirci, Didem; Hendek, Meltem Karsiyaka; Özcan, Gönen; Kul, Oğuz; Anteplioğlu, Tuğçe; Olgun, EbruPurpose (6)-Shogaol is the most prevalent bioactive compound in ginger. The aim of this study was to examine both the prophylactic and therapeutic effects of (6)-shogaol in an experimental periodontitis model. Materials and Methods Thirty-five male Wistar albino rats were divided into four groups. In the healthy group (n=5), no intervention was undertaken. In the periodontitis group (n=10), periodontitis was induced by ligature placement for 14 days. In the prophylaxis group (n=10), periodontitis was induced with ligature placement for 14 days, and during this time, 20 mg/kg/day of (6)-shogaol was administered via oral gavage. In the therapeutic group (n=10), periodontitis was induced with ligature placement for 14 days, and following the removal of the ligature, 20 mg/kg/day of (6)-shogaol was administered via oral gavage for 14 days. Alveolar bone loss was histometrically measured, and malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GP), nuclear factor kappa B (NF-kappa B), receptor activator of nuclear factor kappa B ligand (RANKL), and osteoprotegerin (OPG) were immunohistochemically analyzed. Results Alveolar bone loss was significantly lower in the healthy group than in the remaining groups, as well as in the therapeutic group than in the periodontitis group (p<0.001). RANKL/OPG was significantly higher in the periodontitis group compared to the remaining groups and in the prophylaxis group compared to the therapeutic group (p<0.001). MDA was significantly lower in the healthy group than in the remaining groups (p<0.001). SOD was significantly lower in the periodontitis group than in the prophylaxis and therapeutic groups (p=0.039 and p=0.042, respectively). GP was significantly lower in the healthy group than in the prophylaxis and therapeutic groups (p=0.031 and p=0.002, respectively). Conclusion The administration of (6)-shogaol modulated the RANKL/OPG balance and antioxidant status in rats with ligature-induced periodontitis.Öğe A rare case of feline congenital Toxoplasma gondii infection: fatal outcome of systemic toxoplasmosis for the mother and its kitten(Schluetersche Verlagsgesellschaft Mbh & Co Kg, 2013) Atmaca, Hasan Tarık; Dinçel, Güngör Çağdaş; Macun, Hasan Ceyhun; Terzi, Osman Safa; Uzunalıoğlu, Tuba; Kalender, Hakan; Kul, OğuzThis report describes a case of fatal systemic toxoplasmosis in a 2.5-year-old mixed breed pregnant cat and its kittens. The pregnant cat was presented to the gynecology clinic with symptoms of dystocia. The ultrasound examination revealed the presence of five fetuses in the uterus, three of which were not alive, and consequently a cesarean section was performed. However, the mother cat and the remaining two live kittens died two and ten days after cesarean section, respectively. Pathologically, severe alveolar edema, tachyzoite-like structures in the alveolar macrophages and multifocal necroses in the lungs of mother cat were observed. An intense Toxoplasma gondii immunopositive reaction was observed in the cytoplasms of alveolar macrophages, bronchial and bronchiolar epithelia, necrotic foci in the lungs, and Kupffer cells of the liver. PCR analyses amplified T. gondii DNA in tissue samples of the mother cat and kittens. The present study provides strong evidence for a transplacental transmission of T. gondii infection with deadly outcome for the mother cat, fetuses and kittens. As to the authors' knowledge, this report is the first case of fatal congenital toxoplasmosis in domestic cats in Turkey.Öğe Seasonal Gene Expression Profile Responsible for Hair Follicle Development in Angora Goats(Kafkas Univ, Veteriner Fakultesi Dergisi, 2023) Kul, Bengi Çınar; Bilgen, Nuket; Biskin, Merve; Akkurt, Mustafa Yenal; Çıldır, Özge Şebnem; Özmen, Özge; Kul, OğuzMammals have physiological reprogramming adaptation ability to changing seasonal light and temperature, through their biological clocks maintained by circadian rhythm, photoperiodism and thermoperiodism. Seasonal differences do not only affect vital activities of animals like migration, reproduction, and sleeping, but also cause dramatic changes in their economically important characteristics (e.g. fur quality and fattening level). Mohair is constituted of non-medullary hairs produced by secondary hair follicles in Angora goats and the effects of seasonal differences on mohair structure and related genes are still unknown. We examined the gene expression levels of BMP-2, FGF-5, HOXC13, KAP9.2 and TGFBR2 normalized with GAPDH in skin biopsies taken from Angora goats (n=20) in two different follicle development stages; telogen (in February) and anagen (in June). HOXC13 showed overexpression in anagen phase (P<0.005) whereas expression was undetectable in telogen phase. BMP-2 (P<0.005), FGF-5 (P<0.005) and TGFBR2 (P<0.01) were significantly upregulated in anagen, while KAP9.2 expression showed no difference between two phases. This is the first study on hair follicle-related genes in the angora goat. Additionally, depending the role of HOXC13 in pathways, it suggests that its overexpression may be one of the main factors associated with the non-medullary hair structure in Angora goats.Öğe Türkiye ve Pakistan'da peste des petits ruminants: PPRV'nin patogenezi ve vertical geçişi üzerine doğal enfekte koyun ve keçi sürülerinde araştırmalar(2012) Kul, Oğuz; Toplu, Nihat; Atmaca, Hasan Tarık[Abstract Not Available]
