Öğe The effects of hypertonic NaCl (7.5%) in dogs with induced acute pulmonary artery obstruction(2003) Ulkü R.; Eren N.M.; Cakir O.; Satici O.; Balci A.; Eren S.The study was performed on 11 female and 9 male dogs to investigate the effect of hypertonic NaCl in severe hypotension and shock caused by acute pulmonary artery obstruction. The investigation was performed in Dicle University Healt Research Center (DUHRC). The youngest subject was six months old and the oldest was two years old. Their mean body weight was found as 19 kg. All the subjects were operated under general anesthesia. Invasive measurements of arterial pressure were performed through the right femoral artery by monitorization. All subjects were performed left thoracotomy, entrance to thorax was through 5th intercostal space, and first left then right pulmonary artery were circumferenced loosely with tape. After this, mean pulmonary artery pressures are recorded with the help of monitor by inserting canulla into the pulmonary artery. Pulmonary artery pressures at 3rd, 5th, 10th, 13th, 15th, 18th and 21st minutes after ligation of right main pulmonary artery and left lower lobe pulmonary artery, and mean artery pressures are recorded. Sodium nitroprusside is given to half of the subjects and nitroglycerine is given to the other half in order to lower pulmonary hypertension. Pulmonary arterial pressure measurements following administration of these drugs are recorded. 7.5% of NaCl infusion to subjects is performed in case of hypotension and shock. Isotonic NaCl solution is used in the control group. Mean arterial pressures in group receiving sodium nitroprusside + 7.5% NaCl solution are found significantly higher statistically when compared to group receiving sodium nitroprusside + 0.9% NaCl isotonic solution. Difference in mean arterial pressures were not found statistically significant in the group receiving nitroglycerin + 7.5% NaCl when compared to group receiving nitroglycerin + 0.9% NaCl solution.Öğe Popliteal artery injuries associated with fractures and dislocations about the knee(2001) Subasi M.; Cakir O.; Kesemenli C.; Arslan H.; Necmioglu S.; Eren N.The authors present the results of a retrospective review of popliteal artery injuries associated with fractures and dislocations about the knee. They treated 41 patients with popliteal artery injuries associated with either fractures about the knee or knee dislocations. Thirty-five of the patients were males, 6 females; the mean age was 23 years. The delay before accessing the hospital was 17 hours (range: 3 hours to 10 days). Thirty-two fractures were open. Together with the vascular injury, 12 femoral fractures, 20 tibial and fibular fractures, 5 knee dislocations, 4 femoral + tibial fractures were identified. Twenty-three patients underwent external fixation, 8 internal fixation, 6 plaster cast immobilization, 4 minimal osteosynthesis and plaster cast immobilization. The arterial injury was treated by end-to-end anastomosis in 5 cases, saphenous vein anastomosis in 29 cases and thrombectomy in 7 cases. Nine patients were amputed. Delay in surgery, blunt trauma, extensive soft tissue defect and bone fracture or dislocation, are associated with high amputation rate following popliteal artery injury. The influence of each of these factors alone on the amputation rate could not be evaluated in this study, as no statistically significant correlation could be demonstrated.Öğe Role of propolis on oxidative stress in various tissues of fish(Parlar Scientific Publications, 2014) Aldemir O.S.; Selamoglu Z.; Gulhan M.F.; Cakir O.; Ozdemir I.; Dastan S.D.; Dogan H.The aim of this study was to investigate the therapeutic effects of propolis on biochemical parameters in tissues of rainbow trout (Oncorhynchus mykiss) exposed to Cypermethrin. Cypermethrin is a potential toxic pollutant that directly threats the aquatic ecosystems and environment. Sublethal Cypermethrin concentration of 0.0082 ppm was applied to the fish for 96 h. Propolis is a natural product collected from plants by honey bees. Its polyphenolic components, caffeic acid derivatives and flavonoids in particular, are matter of interest because of their strong antioxidant properties. Therapeutic concentration of propolis has been determined as 10 ppm in a previous study. Herein, malondialdehyde (MDA) levels and catalase (CAT) activities were determined in spleen and heart tissues of rainbow trouts. Results showed that CAT activities and MDA levels increased (P?0.001) in tissues of fish exposed to Cypermethrin compared to control group. CAT activities and MDA levels in the tissues of fish decreased in cyperme-thrin+propolis group (P?0.001) compared to Cypermethrin group. Propolis (10 ppm) on the tissues of the rainbow trout showed significant therapeutic effects. Propolis may serve as an antitoxic agent against pesticide toxicity to aquatic animals.Öğe Warfarin resistance: Interaction between warfarin and Eruca sativa L.
