All rights reserved.OBJECTIVE: Testicular torsion is a condition that manifests with acute pain and can lead to infertility despite urgent surgical intervention. The aim of this study is to investigate the protective and preventive effects of etomidate, an imidazole derivative, a non-barbiturate general anesthetic agent, without analgesic effect, on testicular ischemia-reperfusion injury. MATERIALS AND METHODS: Twenty-four adult male Wistar rats weighing 200-250 g were used in the study. Torsion was created in all rats by rotating left testes 720° clockwise on the day of the experiment. 30 minutes before detorsion, 4 mg/kg etomidate and 10 mg/kg propofol were administered intraperitoneally to the etomidate and propofol groups, respectively. After an hour of ischemia, the left testis was reinstated, and the tissues were repaired according to their physiology. Following 24 hours of reperfusion, the animals were euthanized after ipsilateral and contralateral testes were removed. RESULTS: Etomidate applied before testicular detorsion significantly suppressed germ cell damage and Leydig cell loss in ipsilateral tissue. It did not cause any significant changes in the percentage of necrosis, histological score, and tubule rupture in ipsilateral tissue. Propofol administered before testicular detorsion significantly suppressed the percentage of necrosis only in the ipsilateral tissue. In addition, no signs of damage were observed in the contralateral testis. CONCLUSIONS: These findings show that etomidate administered before detortion creates a protective effect by preventing testicular ischemia- reperfusion injury.Publication Open Access Effects of acute topiramate administration on post-traumatic stress disorder in rats(2022-01-01) YANANLI, HASAN RACİ; DEMİRKAPU M. J., Dogan F. C., Karabag S., Yilmaz A., Celikkol A., YANANLI H. R.Purpose: The aim of this study was to investigate the effects of acute systemic topiramate administration on anxiety index and freezing time, plasma estrogen and progesterone levels, and salivary gland immunoglobulin A in a post-traumatic stress disorder rat model. Materials and Methods: A total of eighteen female Wistar rats used in the study were exposed to predatory odor stress. One week later, saline was administered to the control group and 15 µM and 30 µM topiramate to the treatment groups, after which the animals were exposed to the trauma reminder and their behavior was monitored in the elevated plus maze. At the end of the experiment, blood samples were taken, animals were sacrificed, salivary glands were removed immediately after. Results: Topiramate suppressed anxiety index and freezing time in rats with post-traumatic stress disorder at both 15 µM and 30 µM doses compared to the control group. A positive correlation was observed between plasma estrogen level and anxiety index in the control group, and topiramate suppressed this correlation in a dose-dependent manner. Topiramate did not change the plasma progesterone level, but suppressed the salivary gland immunoglobulin A level at the low dose. Conclusion: These findings obtained in our study indicate that topiramate may be effective in the treatment of posttraumatic stress disorder.
