Öğe Comparison of Thermographic Imaging and Other Diagnostic Techniques in Diagnosis of Cattle with Laminitis(UNIV FED RIO GRANDE DO SUL, 2018) Arican, Mustafa; Hatipoglu, Fatih; Erol, Hanifi; Kanat, Ozgur; Yavuz, Orhan; Parlak, Kurtulus; Koc, OsmanBackground: Lameness results in major economic losses on dairy farms. The proportion of lameness in cows are between 4-55%, the origin of 90% lameness are caused by foot diseases. Hoof abnormalities such as laminitis are major contributors to lameness. Aim of the study, compared with thermographic imaging (IRT) and radiographic, magnetic resonans (MR), computer tomography (CT), histopathological analysis on the diagnosis of laminitis. Materials, Methods & Results: Preliminary, the animals (20 Holstein-Fresian) were selected by lameness examination for evaluation of the for any obvious signs of disease. The animals were examined when rising and walking of the free stalls. Walking was very painful and clinical symptoms of general distress become present for laminitic group. The cows were scored on a 1 to 5 scale for their locomotion (1 = normal locomotion; 5 = severely lame). Thermographic examinations were performed the all animals after the routine clinical examination methods. The infrared images were taken from the dorsal view of all hooves to monitor the temperature of coronary band. All images were scanned using a hand-held portable infrared camera (Wahl, Thermal Imager HSI3000 Series), which was calibrated to ambient temperature and absorptive conditions. Incentives radiological examinations, dorso-palmar and latero-medial shooting was done for using of (Regius Model 110 Konica, Minolta) 70 kV and 30 mAs for each claws. MRI images of all isolated digits were performed at the Department of Radiology, by using Siemens Symphony Erlangen, Germany. Continuous series of transversal, sagital and dorsoplantar scan were obtained from all digit. Computer tomography (CT), isolated digits were performed at the Imaging Department of Radiology, by using Siemens Symphony Erlangen, Germany. CT scanner was used to obtain contiguous slices from the region of the proximal sesamoid bones to the toe. Anterior side (laminar and perilaminar tissues) of the claws was uncovered with electric wheel. Tissue samples were taken 10% buffered formaldehyde solution after establishing a routine laboratory procedure following the prepared paraffin blocks 5 micrometers thick sections with hematoxylineosin dye method according to the staining. It was finally examined by light microscopy. The computer soft ware of the infrared thermal camera showed increased local temperature, by 0.5-1.5 degrees C, between the normal and suspected regions for laminitic cases. Clinically, animals suspected of laminitis were showed general stiffness, lameness during walking difficulty. Examination of the claws was demonstrated of rings and plump appearance was evident in paries ungulae. The main damage was seen during trimming of the sole from no hemorrhages or discoloration of control group. The transversal MRI images provided excellent depictions of anatomical structures when compared to their corresponding pictures. Identifiable anatomic structure was labeled on the line drawings of the limb sections and on the corresponding CT images. Twenty out of 30 claws (65%) were shown laminitis statistical with histopathological examination. In histopathological examination; mononuclear cells and neutrophil granulocytes infilrations and edema, haemorrhagia, mild hyperemia in the lamellar region was remarkable in laminitic cases. Discussion: As a results, thermographic examination may have potential as a detection tool for laminitis. MR transversal images provided excellent depiction of anatomical structures and many biometric research in the bovine hoof can be easily investigated. The usefulness of IRT, MRI, CT in evaluating laminitis in the acute patient remains stil open. The use of diagnostic techniques during the initial active phase of laminitis as a means to increase the understanding of the disease and also serves as a justification for the development of an experiment involving live cows induces laminitis.Öğe Dog massacre with pesticide for theft: Methomyl poisoning(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2019) Ozdemir, Ozgur; Ates, Mehmet Burak; Ortatatli, Mustafa; Terzi, Funda; Avci, Tulay; Hatipoglu, Fatih; Ciftci, Mustafa KemalIn this case report, acute methomyl poisoning in dogs is described by pathological and toxicological findings for the first time in Turkey. Five of the thirty stray dogs that were found dead within 1-2 days after eating the foodstuffs in an industrial area in Konya were necropsied. Grossly, undigested pieces of chicken meat with a mild insecticidal smell in stomach of all dogs were found and toxicological analysis by GC-MS revealed toxic levels of methomyl in the stomach contents (15.7-17.8 ppm) and, intestines, livers and kidneys (1.2-2.9 ppm) also. In addition, histopathologically degenerative and necrotic changes were observed in liver, brain, lung, kidneys and gastrointestinal system mucosa. Postmortem and histopathological examinations and toxicological analyses revealed that deaths were related to methomyl poisoning and it has been subsequently learned from the police officers and printed media that this poison had been deliberately infected to dog food for the purpose of theft committed in the industrial area. Publishing these intentional poisoning events, we have wanted to draw attention to that more serious measures and statutory regulations should be taken by governments about animal rights.Öğe Effect of Acticoat (R) and Cutinova Hydro (R) on wound healing(WILEY-BLACKWELL, 2013) Arican, Mustafa; Hatipoglu, Fatih; Uyaroglu, Aysen; Ozdemir, Ozgur; Ozkan, KadircanIn this study, the effects of the wound-covering materials, Acticoat((R)) and Cutinova Hydro((R)), on wound healing have been studied in rabbit models with open and tissue-lost wounds with full-thickness flank excisions. Rabbits were used as subjects with three groups of four rabbits each, and trial periods of 7, 14 and 21{\uns}days. Four circular wounds, of 1.5 cm diameter were made two on the right (one of them control) and two on the left (one of them control) of the dorsal sides of the abdomen. Acticoat((R)) and Cutinova Hydro((R)) were applied on the wounds with suture for a period of 21 days and one each placed on the right and left sides as control with gauze. Biopsy specimens were taken from the animals at the end of the research period to check the length of the epithelium, epithelial thickness, size of wounds, wound granulation tissue formation and histopathological evaluation for clarity. The Acticoat((R)) group showed better healing and scar formation compared to the Cutinova Hydro((R)) group by macroscopic examination. Epithelial wound length and clarity in terms of statistical difference occurred on day 21 (P <0.05); while the length of the wound epithelium decreased patency, epithelial thickness on days similar to 7, 14 and 21, showed no statistical differences (P >0.05). As a result, the Acticoat((R)) wound dressing was determined as a more reliable for the early wound healing. This study has shown the short-term clinical benefits of hydroactive, polyurethane dressings in the management of acute wounds. However, longer periods of wound healing procedure should be planned for reliable and safe results of wound dressing. It has also been concluded that microbiological analyses should be included for more robust and reliable comparisons.Öğe Effect of Asiaticoside, Collagenase, and Alpha-chymotrypsin on Wound Healing in Rabbits(H M P COMMUNICATIONS, 2016) Ozdemir, Ozgur; Ozkan, Kadircan; Hatipoglu, Fatih; Uyaroglu, Aysen; Arican, MustafaWound dressing materials such as asiaticoside, collagenase, and alpha-chymotrypsin are often used for effective wound healing activity. Objectives.' In this study; the effects of asiaticoside,, collagenase, and alpha-chymotrypsin were studied in rabbit models with open wounds with tissue loss and with full-thickness flank excisions for a period of 21 days, Materials and Methods. Three groups of 4 rabbits were examined during trial periods of 7, 14, and 21 days. Four circular wounds measuring 1.5 cm in diameter were made on the dorsal sides of the animals: 2 on the right and 2 the left. Asiaticoside, collagenase, and alpha-chymotrypsin were applied to wounds daily for a period of 7, 14, and 21 days, while 1 gauzed wound served as the control. All biopsy specimens were histopathologically evaluated for recovery. On day 7, microscopic review showed no differences in wound healing between groups. Results. By day 14, alpha-chyrnotrypsin showed the quickest reepithelialization (P<0.05); and by day 21 asiaticoside and collagenase (P<0.01) showed effective recovery, due to the completion of wound healing for all animals in both groups. Conclusion. Alpha-chymotrypsin is more effective than the other 2 groups for only 14 days. The effectiveness of asiaticoside and collagenase-displayed a more rapid improvement in comparison to alpha-chymotrypsin for healing open wounds with tissue loss for a period of 21 days.Öğe Generalized reactive amyloidosis in a gazelle (gazella gazella)(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2013) Ozdemir, Ozgur; Hatipoglu, Fatih; Karaman, MusaThis report was described generalized amyloidosis in a male gazelle, 1.5 years old. In necropsy, hyperaemia on all the serosal surfaces in abdomen, a hemorrhagic ulcer, 7 cm in diameter, on mucosa of rumen, and whitish colored foci, 1-2 mm diameter, on the surfaces of both kidneys were present. Microscopically, there were homogenous pink depositions in the glomeruli, intertubular interstitium, tubular basement membranes and walls of blood vessel in kidney, lymphoid follicles in spleen, space of Disse in liver and lamina propria of the small intestine. These deposits were seen brick-red color stained with Congo red on tissue sections, but these were not stained with Congo red after treated with potassium permanganate. For this reason, AA (secondary) amyloidosis was evaluated. When stock tissue samples stored in 10% formalin were treated with Lugol and acid sulphuric, amyloid depositions were seen as dark blue. Generalized reactive amyloidosis with ulceration in the rumen was diagnosed. Amyloid deposits in the tissues are not only fresh tissue but also tissue stored formalin can be determined as a macroscopic.Öğe Hemorrhagic bowel syndrome in a holstein cow - case report(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2012) Ciftci, M. Kemal; Yavuz, Orhan; Hatipoglu, Fatih; Ozdemir, OzgurIn this report, hemorrhagic bowel syndrome (HBS) was defined pathologically for the first time in Turkey in a Holstein dairy cow. It was reported that a 4-year-old cow died suddenly with symptoms of loss of appetite, decreased milk yield, dehydration, and abdominal bloating in a dairy farm. Grossly, serosa of jejunum was observed with dark red color and its lumen was completely filled with blood clots. Some parts of jejunum lumen were narrowed due to submucosal and intramural bleeding. Microscopically, necro-hemorrhagic enteritis, and eosinophilic granulocyte and mononuclear cell infiltrations with extensive submucosal hemorrhages were observed. In addition, Gram-positive, rod-shaped and endospore-forming bacteria were seen intensively around of bleeding areas in the lamina propria. The death was concluded to be associated with HBS by macroscopic and microscopic findings, characteristic for the syndrome and in accordance with the literature evaluating this case. HBS causes significant losses in dairy cattle in many countries of the world. This report aimed to point out the importance of the topic, which is the first case report of HBS in Turkey, where dairy cow enterprises are growing rapidly.Öğe The pathology of tuberculosis lesions in allergic skin test (PPD tuberculin) positive cows and detection of tuberculosis agents with PCR in milk samples(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2018) Tuncay, Cigdem; Hatipoglu, FatihThe aim of this study was to determine tuberculosis (Tb) agents in milk and the pathologic changes in the tissues and organs of 100 PPD Tb-positive cows that were intended for slaughter. Milk samples were taken before slaughtering and PCR analysis was conducted to detect the Tb agent. In postmortem examinations, the lungs, liver, mammary glands, spleen, kidneys, and heart were collected for macroscopic and histopathological examinations. Out of the 100 PPD positive cows, lesions of Tb were observed in 75 cows. In the microscopic examination, Tb was identified in the lungs (51 cases), liver (61 cases), and in both the liver and lungs (37 cases). Although mammary Tb was suspected in 32 cows in macroscopic examinations, in microscopic examinations these cases were evaluated as chronic pyogenic abscesses mastitis. No Tb agents were detected by PCR analysis in milk samples taken from the cows before slaughter. Therefore, periodical milk inspections are suggested for controlling agents in milk. In some of the Tb PPD positive animals (25 cases), no changes were detected; therefore, there is a need to improve tests with higher sensitivity for the antemortem diagnosis of Tb. Moreover, people involved in the livestock sector should be trained about Tb, hygiene rules, and disease-free herds.
