Öğe Ankara keçilerinde propofol ve izofluran anestezisinin oksidatif stres üzerine etkileri(2011) Pekcan, Zeynep; Çınar, Miyase; Gürkan, Mehmet; Kumandaş, AliBu çalışma, Ankara keçilerinde propofol ve izofluran uygulamasının kan malondialdehit ve antioksidan düzeyleri üzerine etkilerini belirlemek amacıyla gerçekleştirildi. Araştırma, vücut ağırlıkları 33.8-49 kg arasında değişen 7 adet klinik olarak sağlıklı, ergin, dişi Ankara keçisi üzerinde yürütüldü. Hayvanlara anestezi indüksiyonu için ortalama 6.561.42 mg/kg propofol bolus şeklinde intravenöz olarak uygulandıktan sonra 1 saat süre ile %1-3 konsantrasyonunda izofluran %100 oksijen ile birlikte verildi. Tüm hayvanlardan propofol uygulamasının öncesinde, indüksiyon sonrasında ve izofluran uygulamasından 15, 30, 60, 120 dakika ve 24 saat sonra kan örnekleri alındı. Alınan kan örneklerinin plazmalarında malondialdehit (MDA), vitamin A ve ?-karoten düzeyleri ile eritrositlerde süperoksid dismutaz (SOD) ve katalaz (CAT) aktiviteleri belirlendi. Propofol ve izofluran anestezisi yapılan keçilerde anestezi süresince ve sonrasında plazma MDA, vitamin A düzeylerinde ve eritrosit SOD, CAT aktivitelerinde istatistiksel olarak önemli bir değişiklik tespit edilmedi. Beta karoten düzeylerinde ise propofol uygulamasından sonra istatistiksel olarak önemli bir artış olduğu belirlendi (P0.05). Sonuç olarak, Ankara keçilerinde propofol ve izofluran anestezilerinin kan MDA ve ölçülen antioksidan parametre düzeyleri üzerine olumsuz bir etkisinin olmadığı tespit edildi.Öğe Assessing the Early Post-Operative Analgesic Effects of Intra-Operative Lidocaine-Bupivacaine Use at the Incision Line and/or Around the Ovary in Ovariohysterectomy Operations of Dogs on Pain Mediators(Zoological Soc Pakistan, 2024) Ulukan, Gökhan; Pekcan, Zeynep; Sarıtaş, Zülfükar Kadir; Etikan, İlker; Sayiner, Serkan; Zabitler, Feride; Özgencil, Fatma EserThe present study investigated the effectiveness of intra-operative bupivacaine-lidocaine (BLK) combination administration concurrently with meloxicam, a non-steroidal anti-inflammatory drug (NSAID), on the Glasgow Composite Pain Scale Short Form (GCPS-SF) scores and pain mediators in the early post-operative ovariohysterectomy (OHE) period in 30 female dogs of different breeds and ages divided into three equal groups. OHE is reportedly associated with moderate pain. BLK was administered inside the ovarian bursa 10 min before ovary removal in Groups (G) 1 and G2 and linear to the incision line 10 min before entering the abdomen in G1. G3 was the control group. The intergroup comparison of pain mediators and GCPS-SF scores showed no significant difference between the GCPSSF scores at postop0, postop2, postop4, postop8 and postop24 h and the cortisol, TNF-alpha, IL1-beta and NO levels determined at the same timepoints. TNF-alpha at postop24 h showed a significant positive correlation with the postop0 h GCPS-SF score. NO at postop8 h showed a significant negative correlation with the postop4 h GCPS-SF score. However, since these results were not simultaneous, they were disregarded. Although there was no statistically significant difference in post-operative pain and stress among the three groups, surgical stress was higher in G3, as indicated by high postoperative cortisol levels, which suggested the other two protocols involving BLK to be remarkable. Hence, using G1 and G2 protocols appeared feasible considering the post-operative cortisol stress hormone values. Nevertheless, further studies with larger samples are warranted to confirm these inferences.Öğe Autologous serum effect on corneal endothelial damage in the phacoemulsification rabbit model(Derman Medical Publ, 2017) Usta, Gülşah; Oğurel, Reyhan; Onaran, Zafer; Pekcan, Zeynep; Oğurel, Tevfik; Karsli, Birkan; Gökçinar, Nesrin BüyüktortopAim: This study used specular microscopy to evaluate the possible effects of applying autologous serum to the anterior chamber on the corneal endothelial damage created by the ultrasonic vibrations of phacoemulsification (PHACO) in rabbits. Material and Method: The study, which was approved by the Ethics Committee, involved both eyes of nine 5 month-old (about 3 kg) New Zealand genus albino male rabbits. Group 1(6 eyes) received only an application of 0.2 ml autologous serum; Group 2 (6 eyes) received only the ultrasonic vibrations for 20 seconds: and Group 3 (6 eyes) received 0.2 ml autologous serum followed by ultrasonic vibrations for 20 seconds. Measurements were made before the intervention and at the 1st and 7th days postoperatively using specular microscopy, intraocular pressure, and pachymetry metrics, and the data were compared statistically. Results: Postoperative 1st week, the cornea thickness increased from 385 mu to 445 mu in Group 2 (PHACO only) and from 398 mu to 402 mu in Group 2 (PHACO plus autologous serum). However, this difference was not statistically significant. Postoperative 1st day standard deviation (p < 0.05) and variation coefficient (p < 0.05) values of the specular microscopy parameters for Groups 2 and 3 were higher than for Group 1. Postoperative 1st week it was observed that the parameters of the three groups were similar and had returned to the preoperational values. Between the endothelial cell numbers, the cell density, the cell space average, the largest and the smallest percentage of the cell and the hexagonal cell area values, there were no statistically significant differences at the three measurement time points. Discussion: This study showed that, after the phacoemulsification process, autologous serum applied to the anterior chamber can, by positive possible effects on endothelial pump functions, reduce corneal edema without morphological changes, which can be confirmed with specular microscopyÖğe Cardiovascular effects of thiopental-sevoflurane compared withthiopental-isoflurane in angora goats undergoing ovariectomy(2019) Karslı, Birkan; Yağcı, İlknur Pir; Kumandaş, Ali; Pekcan, Zeynep; Kalender, HakanAim: The purpose of this study was to evaluate the effects of inhalation anaesthetics on cardiovascular functions in 16 healthy female Angora goats undergoing ovariectomy. Material and Methods: Anaesthesia was induced with thiopental sodium then maintained with isoflurane or sevoflurane in oxygen. Cardiovascular parameters were measured before and at 0, 15th, 30th, 60th and 90th minutes after induction of anaesthesia. Recovery variables including time to extubation, first lift of the head, thoracic recumbency and standing up were also recorded. Results: The mean induction dose of thiopental was 18.23 ± 3.87 mg / kg. There were no significant differences between groups for heart rate (HR), respiration rate (RR), noninvasive blood pressure and body temperature measured prior to and under anaesthesia. All animals recovered uneventfully in both groups. Conclusion: There were no statistical differences between groups for their cardiovascular parameters and recovery times although the results of this study showed a rapid recovery time in each parameter for sevoflurane anaesthesia. On the basis of the results, sevoflurane and isoflurane are suitable inhalation anaesthetics in goats.Öğe Clinical and Surgical Evaluation of Perineal Hernia in Dogs: 41 Cases(Kafkas Univ, Veteriner Fakultesi Dergisi, 2010) Pekcan, Zeynep; Besalti, Omer; Sirin, Yusuf Sinan; Caliskan, MuratThe purpose of the study was to report the clinical and surgical records of perineal hernia and associated rectal pathology with epidural morphine analgesia in 41 dogs. Fourty one dogs suffered from perineal hernia were included into the study with the age varied from 4.5 to 16 years. Eleven dogs had bilateral while the other 30 had unilateral (17 right, 13 left) perineal hernia. The clinical signs were perianal swelling (n=41), severe tenesmus (n=19), dyschesia (n=9), proctitis (n=7), fecal incontinence (n=4), stranguria (n=2) and hematuria (n=1). Associated rectal pathologies were diverticulation (n=15), dilatation (n=4), deviation (n=3) and sacculation (n=1). The rectal diverticulum was corrected by extraluminal plication (n=12) or rectal resection (n=3). Internal obturator muscle flap transposition was used to repair the hernia in all cases. Postoperative pain was subjectively evaluated and scores were "no pain" in 10 cases, mild in 28 cases, moderate in 3 cases. Mean follow-up time was 27.3 months (range 4 months to 5 years) and the recurrence was observed only in three cases postoperatively. In conclusion, combined perineal herniorraphy with internal obturator muscle transposition and rectal wall repairment can be carried out at the same time and epidural morphine administration provide adequate analgesia for these operations.Öğe Comparison of Propofol-Remifentanil and Propofol-Fentanyl Anesthesia During Ovariohysterectomy in Dogs(Kafkas Univ, Veteriner Fakultesi Dergisi, 2013) Kurum, Baris; Pekcan, Zeynep; Kalender, Hakan; Kumandas, Ali; Can Mutan, Oya; Elma, ErtugrulThe aim of the study was to evaluate the cardiorespiratory and clinical effects of propofol and remifentanil anesthesia compared to propofol and fentanyl anesthesia during ovariohysterectomy in dogs. Sixteen healthy dogs were randomly assigned to two groups. After premedication with atropine, anesthesia was induced with propofol and maintained with the infusion of propofol at a dose of 0.5 mg/kg/min. Once stable anesthesia was achieved, 1 mu g/kg remifentanil or 2 mu g/kg fentanyl was administered intravenously, and infusion was begun at a dose of 0.6 mu g/kg/min and 0.5 mu g/kg/min, respectively. Cardiorespiratory variables were recorded after propofol administration combined with remifentanil or fentanyl at 10-min intervals, and the quality of anesthesia, return of spontaneous ventilation, head lift and sternal position were also recorded. Apnea was observed after remifentanil and fentanyl administration in all dogs. Heart rate, systolic and mean arterial blood pressures tended to decrease rapidly after remifentanil and fentanyl administration, and during the first 20 min, in both groups. Although the difference between times was significant, the difference between groups was statistically insignificant. Recovery periods were longer in the fentanyl group than in the remifentanil group. The administration of propofol with remifentanil or fentanyl provides a stable haemodynamic state and depth of anesthesia with a constant infusion, and remifentanil could be preferred to fentanyl when aiming a rapid recovery period.Öğe Comparison of the Efficacy of Gutta-percha and Thermafil in Endodontic Treatment in Dogs(Academic Journals Inc, 2011) Pekcan, Zeynep; Kurum, Baris; Gurkan, Mehmet; Kumandas, Ali; Karsli, Birkan; Elma, ErtugrulEndodontic treatment is performed to save periodontally intact teeth with pulpal inflammation, infection or necrosis. There are some endodontic filling materials used in dogs. The aim of this study was to evaluate the clinical application of two different root canal treatments with thermafil and gutta-percha, in dogs. Nineteen tooth roots were treated in 11 dogs. The treated teeth comprised of six first incisors, five second incisors, three third incisors and five canine teeth. Root canal treatment was decided to be performed after clinical and radiological examination. The depth of the gingival sulcus, dental mobility, haemorrhage after probing and change of tooth colour were assessed and periapical lesions and root resorption were evaluated after dental radiographic examination. In clinical examination, exposed dental pulp, dental mobility, discoloration and fracture were recorded in 14, 3, 6 and 4 teeth, respectively. Periapical lesions were recorded in 4 teeth and root resorption was determined in 2 teeth during dental radiological examination. The root canal was filled with gutta-percha in 12 tooth roots and with thermafil in 7 tooth roots. Afterwards, access openings were closed with a composite resin. Of the 12 tooth roots obturated with gutta-percha, 4 were filled with 55 mm long-gutta-percha plugs manufactured specifically for carnivores and the others were obturated with commercially available 25 mm-long gutta-percha plugs. Both techniques were observed to be applicable; however, obturation with thermafil proved to be much easier. As regards the time needed for application, thermafil was applied within shorter periods compared to gutta-percha. However, the results obtained showed that, instead of using gutta-percha cones and a file of the same size, it would be better to prefer a smaller size thermafil cone to obturate the full length of the root canal.Öğe The contribution of thiamine, pyridoxine and cyanocobalamine combination on nerve regeneration in rats with experimentally induced sciatic injury(Medwell Online, 2007) Besalti, Ömer; Ergin, İrem; Ünlü, Ece; Pekcan, Zeynep; Koskan, ÖzgürThe aim of this study was to investigate the role of thiamine, pyridoxine and cyanocobalamine combination on nerve regeneration after experimentally induced crush injury in thirty adult, male wistar rats. Sciatic function index and Toe spreading reflex and nerve conduction studies on exposed sciatic nerve were carried out before sciatic crush injury and after three weeks of treatment. The experiment group received thiamine (33 mg kg(-1)), pyridoxine (33 mg kg(-1)) and cyanocobalamine (0.5 mg kg(-1)) injections intramuscularly for 3 weeks and the control group received equal volumes of saline injections. Toe-spreading reflex were better in the experiment group than the controls after treatment (p<0.05). There was no significant difference in regard to DL, DCMAP, PCMAP and NCV between both groups (p<0.05). In conclusion the beneficial effect of thiamine, pyridoxine and cyanocobalamine combination was not found in regard to the electrophysiological parameters measured. However clinical improvement was superior in the experiment group than the control group.Öğe Cutaneous Malignant Melanoma in a Cat(Kafkas Univ, Veteriner Fakultesi Dergisi, 2009) Karakurum, Mehmet Cagri; Pekcan, Zeynep; Ozmen, OzlemMelanomas are neoplasia of melanocytes and melanoblasts which may in benign or malign character. Malign melanoma is typically considered as a rare neoplasm in cats. In this case report, the clinical and histopathological findings of cutaneous malignant melanoma was reported in a sixteen year-old cat. At the same time, this is the first report of cutaneous malignant melanoma in a cat in Turkey..Öğe Dermal squamous cell carcinoma (avian keratoacanthoma) in parakeets(Ankara Univ Press, 2010) Yildirim, M. Ziynet; Ozturk, Sibel E. Bilgihan; Pekcan, Zeynep; Kutsal, Osman; Vural, Sevil AtalayTumor suspected operation materials obtained from eight parakeets are evaluated clinically, pathologically and immunohistochemically. The age of the parakeets varied from seven months to nine years old. Four were male, one was a female and the sexes of the rest three were not identified. Six of the operation materials were taken from the above the tail while the other two from beneath the wings. Evaluated tumors were observed to be hard in consistency and whitish color on cut surface. At histopathological examination; it is seen that hyperchromatic nucleated, big, ovoid shaped, pale eosinophilic cytoplasmated cells had formed groups in dermis. Keratinized horn pearl formations are identified in the centers of most of these cell groups. Within the horn pearl formations hyperkeratotic, parakeratotic changes and calcifications are found. In some cases inflammation areas consisting of heterophil leukocytes, lymphocytes and plasma cells in the dermis are observed. Also in histopathological examination of one case, tubercle formations made of coagulation necrosis in the center surrounded by heterophil leukocytes, macrophages, epithelioid cells, lymphocytes and foreign body giant cells are found as well as tumoral formations. Groups of cudgel shaped, red colored bacteria are found in Ziehl-Neelsen staining of the sections. Tissues are stained for proliferating cell nuclear antigen (PCNA) and p53 proteins immunohistochemically in order to interpret mitotic activity and malignancy of the tumor. TUNEL method is applied to the tissues to evaluate apoptosis.Öğe Effects of Halothane and Isoflurane Anaesthesia on Antioxidant Enzymes in Dogs(Medwell Online, 2010) Yarsan, Ender; Gurkan, Mehmet; Pekcan, Zeynep; Ince, Sinan; Kumandas, AliFree radicals, along with the impairment of biological membranes and cellular structures and increased biological activity, come out with the results of the changes in the activity of the enzymes followed by the damages of cellular function and metabolism This condition was attributed to the initiation effects of anaeshetics and other drugs which are used throughout the general anaesthesia General anaesthesia which is constructed with using many drugs which have various physicochemical structures is a condition affecting lipid peroxidation in the organism directly or indirectly In the frame of the study, the effects of halothane and isoflurane used in the anaesthesia on Malonyldialdehyde (MDA) concentration were investigated The study was carried out on 14 dogs with various breeds, ages and sexes which were admitted to Kirikkale University, Faculty of Veterinary Medicine and with various signs of complaint and determined as healthy according to the clinical and haemotological examination In the experiment, halothane (1-2 5%) and isoflurane (1-3%) were investigated as the anaesthetic substances Diazepam (0 3 mg kg(-1), IM) was administered as preanesthesia and thiopenthal sodium (10 mg kg(-1), IV) was administered for the induction of anesthesia to dogs Halothane and isoflurane were administered to the dogs in the first and second group, respectively The duration of anaesthesia was determined as 60 mm Five blood samples were taken from the animals at the time prior to premedication, immediately before the gas anaesthesia, after 1 h of the initiation of anaesthesia, 3 and 24 h after the end of anaesthesia into the heparinated tubes Malonyldialdehyde levels were measured in plasma During the experimental period, body temperatures, heart rate, respiration rate and blood oxygen saturation values were recorded Malondialdehyde levels measured during the halothane anaesthesia were numerically lower than those determined in isoflurane anaesthesia in same time period However, they reached the same levels prior to the anaesthesia within 24 h m both groups The differences between the two groups were statistically insignificant (p>0 05) Additionally, there were no significant differences in body temperature, heart rate, respiration rate and blood oxygen saturation values between the anaesthethic drugs Results of the comparisons of time and drug type showed that anaesthesia procedures using both halothane and isoflurane did not have any negative effect on the oxidative metabolism in dogsÖğe The Effects of Ketoprofen and Meloxicam on Bone Healing in Rat Model: A Comparative Dual Energy X-Ray Absorptiometry Study(Kafkas Univ, Veteriner Fakultesi Dergisi, 2012) Kurum, Baris; Pekcan, Zeynep; Karsli, Birkan; Kumandas, Ali; Elma, ErtugrulPain control is a common clinical approach in trauma and postoperative care especially complicated orthopedic surgeries to ease the deleterious effects of pain. Various kinds of pain killers have been used, and nowadays nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used drugs for pain control purposes. Prostaglandin-endoperoxide synthetase, also commonly called cyclooxygenase (COX), is one of the key enzymes in prostaglandin bio-synthesis. The COX enzymes have subgroups of enzymes, each of which suppresses different inflammatory mediators. These enzymes are involved in different functions, some of which are essential for continuity of physiological processes. Thus, NSAIDs are expected not to cause any change of functions of some enzymes while suppressing others. Among the COX enzymes, COX-1 is associated with gastrointestinal system functions and gastrointestinal mucosa while COX-2 is associated with inflammation and pain. Like most drugs, NSAIDs have known and possible side effects. In various studies related to NSAIDs, inhibitory effects of conventional NSAIDs with non-selective effects and specific COX-2 inhibitors on bone healing have been reported. In this study, the effects of ketoprofen and meloxicam on bone fracture healing induced in 24 adult male Wistar rats was studied by Dual Energy X-Ray Absorptiometry (DEXA). The results indicates that meloxicam inhibits the fracture healing to some degree.Öğe Effects of mesenchymal stem cell and amnion membrane transfer on prevention of pericardial adhesions(WALTER DE GRUYTER GMBH, 2020) Kabalci, Mehmet; Sahin, Mustafa; Pekcan, Zeynep; Zengin, Mehmet; Dogru, Mehmet Tolga; Kisa, UclerBackground: To investigate and compare the antiadhesive/antifibrotic effects of mesenchymal stem cells (MSC) and amnion membrane transfer (AMT) in a rat model. Material and methods: Three experimental and sham groups were formed using 30 Wistar-Albino rats. AMT and MSC were applied to the related groups. The control group was not treated. After 12 weeks follow-up, intracardiac blood and cardiac-pericardiac tissue samples were taken. The severity of adhesions and fibrosis were scored macroscopically and microscopically with Hematoxylin/ Eosin and Masson's trichrome staining. TNF-alpha, TGF-beta, IL-1, PDGF, FGF, VEGF and Caspase-3 levels were measured with the ELISA method. Results: Severe adhesions were observed in the AMT and control groups, but no adhesion was present in the MSC group. Pericardial thickness, increased vascularity, fibrosis, and collagen accumulation were similar between control and AMT groups, but were less in Sham and MSC groups. Between MSC and AMT groups, only Caspase-3 level was different, which is an apoptosis marker. Conclusion: The positive effects of MSC on adhesion, which we achieved in our study, suggest that it may prevent adhesion. AMT did not provide a positive effect. The correlation of Caspase-3 with postoperative adhesion/fibrosis should be examined in more detail.Öğe The effects of short term propofol administration on pancreatitis formation in dogs(Ankara Univ Press, 2017) Pekcan, Zeynep; Karaisaoglu Ongan, Emel FundaEven the incidence of a drug-induced pancreatitis is rare there are more than 85 different drugs have been reported that induces pancreatitis. FDA have been reported that propofol administration resulted in pancreatitis in 25 human cases. Even though there are several reports pointed out an increase in blood lipid and triglyceride levels after propofol administration, there are no studies investigated the possible association between the use of propofol and consequently occuring pancreatitis in veterinary medicine. The aim of this study was to evaluate the possible side-effects of propofol administration on pancreatic tissue in dogs. Twenty healty dogs were anesthetized for at least one hour. Bloods were collected to evaluate the serum amylase, lipase, ALP, AST, GGT, cPLI, cholesterol, triglyceride, Ca and glucose levels before and after propofol administration, during recovery period and after 4th and 24th hour. It was recorded that the serum glucose, calcium and triglyceride levels were increased during anesthesia, on the contrary serum amylase, lipase, ALP, AST, GGT, and cholesterol levels were decreased. The alterations in cPLI was insignificant. Clinical evaluation is not revealed any evidence of pancreatitis in neither of the animals. As a result, it was concluded that although the triglyceride levels were found to be elevated during propofol administration, it did not cause any clinical manifestations regarding pancreatic activity.Öğe Effects of Short-Acting Anaesthetics on Haemodynamic Function as Determined by Doppler Ultrasonography in Rabbits(Kafkas Univ, Veteriner Fakultesi Dergisi, 2011) Kaya, Mahir; Pekcan, Zeynep; Sen, Yusuf; Boztok, Basak; Senel, Oytun Okan; Bumin, AliThis study was carried out to determine the effects of short-acting anaesthetics on haemodynamic function determined by Doppler ultrasonography. Prior to anaesthesia, Doppler parameters [peak systolic blood flow velocity (psBFV), end-diastolic blood flow velocity (edBFV), minimum diastolic blood flow velocity (mdBFV) and resistive index (RI)] were obtained from the right common carotid artery (CCA), abdominal aorta (AA) and right kidney in New Zealand rabbits (n= 24). Animals were then divided into 3 groups to be anaesthetized with propofol (Group P), 2.5% thiopental sodium (Group T) and xylazine/ketamine HCl (Group XK). During anaesthesia the same Doppler measurements were made. Compared with baseline values, psBFV obtained from CCA increased in Group P (P < 0.02) and insignificantly changed in Groups T and XK. psBFV measured from AA in Groups T and XK decreased as compared with baseline values. In the right kidney, psBFV in Group P and edBFV in Group T increased, whereas RI value in Groups T and XK decreased. In conclusion, comparing baseline values, propofol anaesthesia did not significantly alter RI measured from CCA and kidney and blood flow velocities measured from AA. The data suggest that propofol anaesthesia in rabbits results in minimal changes in Doppler parameters.Öğe How Can Better Anaesthetic Combinations Be Performed? A Review of Current Knowledge(Kafkas Univ, Veteriner Fakultesi Dergisi, 2016) Pekcan, ZeynepIn the ever-developing world, the recent years have brought about a wide range of novelties and significant developments in the fields of veterinary anaesthesia and analgesia. In the not-too-distant past, it was believed that the pain threshold of animals was high and that pain was not felt by animals during surgery, when they were anaesthetised. It was considered that the only analgesic drugs that could be used during operation were non-steroidal anti-inflammatory drugs. Today, these suppositions are all accepted as fallacies across the world, and it is well-known that the administration of analgesic drugs should be started in the preoperative period. This article describes pain in animals, how pain perceived by the operated animal can be recognised, and if not treated, to which complications pain may lead. Furthermore, in the last part of the manuscript, complications associated with the use of atropine and alpha 2-agonist combinations, and the adverse effects of anaesthesia-induced hypotension are also explained. This review is intended to provide an insight into recently developed novel practices and to elucidate some main issues, which may be confusing for the veterinary practitioner.Öğe Investigation of the diagnostic value of serology, cytology and polymerase chain reaction in cat toxoplasmosis(Ankara Univ Press, 2017) Yasa Duru, Sibel; Kul, Oguz; Babur, Cahit; Deniz, Ahmet; Pekcan, Zeynep; Pir Yagci, IlknurToxoplasmosis is an infectious disease affecting most of the mammalian and aviary animals caused by Toxoplasma gondii. In this study, diagnostic values of bronchoalveolar lavage, biopsy and PCR and their practical implementation ways were questioned. The results of the each test were evaluated. Additionally, incidence of toxoplasmosis among seropositive cats were investigated by T. gondii and oocyst shedding screened in the stool samples, as well. The material of the study was constituted by blood, stool and bronchoalveoloar lavage samples taken from totally 102 cats. Bronchoalveolar lavage samples were evaluated for cytologic examination. In PCR analysis, T. gondii B1 primary sets were used and conventional-PCR procedure was applied. Antibodies to T. gondii were found in 49 (48,03%) of 102, with titers of 1/16 in 41 (40,19%), 1/64 in 8 (7,84%) cats. Only one cat exhibited systemic toxoplasmosis. In conclusion, although the seroprevalance was 48.03%, systemic toxoplasmosis rate was found 0.98% (1/49) with a lower percentage.Öğe Kedilerde toksoplazmoz tanısında seroloji, sitoloji ve polimeraz zincir reaksiyonunun tanısal değerlerinin araştırılması(2017) Duru, Sibel Yasa; Kul, Oğuz; Babür, Cahit; Deniz, Ahmet; Pekcan, Zeynep; Yağcı, İlknur PirToksoplazmozis, Toxoplasma gondii tarafından meydana getirilen, çok sayıda memeli ve kanatlı hayvanda görülen, protozoer bir enfeksiyondur. 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 Köpeklerde kısa süreli uygulanan propofolün pankreatitis oluşumuna etkisi(2017) Pekcan, Zeynep; Ongan, Emel Funda Karaisaoğluİlaca bağlı pankreatitis şekillenmesi nadir olmakla beraber bugüne kadar 85'in üzerinde değişik ilacın pankreatitise neden olduğu bildirilmiştir. Yakın tarihte FDA'ya propofol uygulanmasından sonra pankreatitis geliştiğini bildiren 25 ayrı vaka bildirimi vardır. Veteriner çalışmalarında ise propofol uygulaması sonrasında hiperlipidemi ve trigliserid seviyesinde yükselmeler olduğu bildirilmesine rağmen, pankreas üzerine muhtemel etkisi araştırılmamıştır. Bu çalışmanın amacı, propofol uygulanmasının pankreas üzerine etkilerini değerlendirmektir. Çalışmada 20 sağlıklı köpek en az bir saat süre ile anesteziye alındı. Hayvanlardan anestezi öncesinde ve sırasında, uyanma sırasında, uyandıktan 4 ve 24 saat sonra kan alınarak serum amilaz, lipaz, kolesterol, trigliserid, ALP, AST, GGT, cPLI, kalsiyum ve glikoz seviyeleri değerlendirildi. Buna göre anestezi sırasında serum glikoz, kalsiyum ve trigliserid değerleri yükselirken amilaz, lipaz, ALP, AST, kolesterol ve GGT değerlerinin düştüğü kaydedildi. Serum cPLI analizlerinde ise istatistiksel olarak anlamlı bir değişiklik kaydedilmedi. Klinik olarak değerlendirildiğinde ise propofol uygulaması sonrasında hiçbir hayvanda pankreatitis bulgusuna rastlanmadı. Sonuç olarak bir saat süre ile uygulanan propofolun, serum trigliserid düzeyini yükselttiği, ancak pankreas üzerine etkisi değerlendirildiğinde klinik açıdan güvenli olduğu kanısına varılmıştır.Öğe Magnetic resonance imaging findings in dogs with thoracolumbar intervertebral disk disease: 69 cases (1997-2005)(Amer Veterinary Medical Assoc, 2006) Beşaltı, Ömer; Pekcan, Zeynep; Şirin, Y. Sinan; Erbaş, GoncaObjective-To determine magnetic resonance imaging (MRI) abnormalities in dogs with intervertebral disk disease (IVDD) and develop a classification scheme for IVDD in dogs based on MRI findings. Design-Retrospective case series. Animals-69 dogs. Procedure-Medical records of dogs admitted because of thoracolumbar IVDD in which MRI of T9 through L7 had been performed were reviewed. Results-A total of 759 intervertebral disk spaces were examined. Of these, 342 (45.1%) were classified as having a normal MRI appearance; the remaining 417 (54.9%) had various types of IVDD. Disk degeneration was identified in 276 disk spaces in 56 dogs, bulging of the intervertebral disk was identified in 37 disk spaces in 24 dogs, disk protrusion was identified in 54 disk spaces in 32 dogs, and disk extrusion was identified in 50 disk spaces in 48 dogs. Cartilage endplate changes were identified in 35 vertebrae in 17 dogs, and increased signal intensity of the spinal cord was identified in 21 dogs. Conclusions and Clinical Relevance-Four types of IVDD (disk degeneration, bulging of the intervertebral disk, disk protrusion, and disk extrusion) were identified on the basis of MRI findings in dogs with thoracolumbar IVDD. We recommend that a standardized nomenclature be adopted for the various types of thoracolumbar IVDD in dogs.
