Öğe An Experimental Comparison of the Effects of Propolis, Curcumin, and Methylprednisolone on Crush Injuries of the Sciatic Nerve(Lippincott Williams & Wilkins, 2015) Yuce, Serdar; Gokce, Emre Cemal; Isikdemir, Ahmet; Koc, Emine Rabia; Cemil, Duran Berker; Gokce, Aysun; Sargon, Mustafa F.Background: Propolis and curcumin have antioxidant, anti-inflammatory, immunomodulatory, and neuroprotective features. The goal of this study was to determine the effects of propolis and curcumin on nerve healing in rat sciatic nerve crush injuries and to compare these effects with results obtained using steroid treatment. Methods: In the sham group, the right sciatic nerves of rats were dissected and exposed, and the skin was closed without any additional manipulation. In the control group (group C), after the right sciatic nerves of rats were exposed, crush damage was inflicted using a surgical clamp. In the control-methylprednisolone group, crush injuries were inflicted on sciatic nerves as in group C. After injury, 1-mg/kg methylprednisolone was administered daily for 6 days and was then tapered for 4 days. In the curcumin group, crush injuries were inflicted on sciatic nerves as in group C. Then, 100-mg/kg curcumin was given every day. In the propolis group, crush injuries were inf licted on sciatic nerves as in group C. Then, 200-mg/kg propolis was given every day. Rats were evaluated after 28 days using functional (walking track analysis and electrophysiological measurements), histomorphometric, electron microscopic, and muscle weight measurements. Results: Compared to the control groups, the curcumin and propolis groups had better functional (walking track analysis and electrophysiological) results after experimental peripheral nerve crush injury. Conclusions: Curcumin and propolis, 2 traditional drugs, had a positive effect on nerve crush injuries. We are convinced that they can be used to support routine treatment in such nerve injuries.Öğe New hemostatic agent: the effect of Ankaferd Blood Stopper on healing wounds in experimental skin incision model(Tubitak Scientific & Technological Research Council Turkey, 2014) Yuce, Serdar; Candirli, Celal; Yenidunya, Sibel; Muslu, BunyaminAim: To conduct a histopathological evaluation of the effects of Ankaferd Blood Stopper (ABS) on healing wounds in a rabbit skin incision model. Materials and methods: Incisions were performed on the backs of rabbits. The first incision was allowed to undergo normal secondary healing. ABS (1 mL) was applied to the second incision, which was subsequently allowed to undergo secondary healing. The third incision was sutured. ABS (1 mL) was applied to the fourth incision, which was subsequently sutured. During the wound healing period, the histopathologic signs of ulceration, inflammation, the proliferative phase, and the extent of early remodeling were comparatively evaluated by performing biopsies on days 5, 10, and 30. Results: For all of the ABS-treated wounds, the appearance of the cavities during the early stage and the disappearance of the cavities during the late stage were observed. In addition, on days 5-10, the inflammatory granulation tissue in the ABS-treated wounds was less than in the normal wounds. By day 30, all of the wounds had achieved the same symptomatic state. Conclusion: As ABS does not exert any negative effects on wound healing, this agent is a secure and effective method for achieving hemostasis.Öğe Our Experiences in the Surgical Treatment of Bayne Type III and IV Radial Longitudinal Deficiencies(Modestum Ltd, 2015) Komurcu, Mahmut; Yuce, Serdar; Yavuz, Osman Yuksel; Uras, Ismail; Uygun, Murat; Kurklu, MustafaRadial longitudinal deficiencies are characterized by radial deviation of the wrist, a short and bowed forearm and a non-functional or absent thumb. The deformity is caused by varying degrees of underdevelopment and malformation including hypoplasia of the bones, joints, muscles, tendons, ligaments, nerves and vessels. This study describes our results from centralization in 8 limbs with Bayne type III-IV radial longitudinal deficiencies. We reviewed 8 limbs from 6 patients with a centralization performed between 2002 and 2010. The median patient age at the time of the operation was 2.75 years (range 2-14 years). The sex ratio was 4 male and 2 female. All patients underwent centralization. One patient had an additional 6.5 cm elongation of the ulna bone by means of a circular external fixator (CEF). The median follow-up time from centralization was 4,5 years (range 2-10 years). The result was considered to be excellent in 4 cases, good in 3 cases and fair in 1 case. Radial deviations regenerated in all cases. During follow-up, a radial deviation of 15 degrees developed in one patient; this deviation did not require surgical correction. Hand and wrist movements were within acceptable levels. Movement and function of the wrist and forearm can be obtained through centralization of the wrist and ulnar elongation when necessary. A cosmetically pleasant appearance can be ensured.Öğe What is your diagnosis 5?(Deri Zuhrevi Hastaliklar Dernegi, 2015) Erpolat, Seval; Yuce, Serdar; Yenidunya, Sibel[Abstract Not Available]
