Öğe Comparison of immunological, histological and oxidative effects of felbamate and levetiracetam in traumatic brain injury(Verduci Publisher, 2020) Bayhan, I; Turtay, M. G.; Ciftci, O.; Cetin, A.; Basak, N.; Oztanir, M. Namik; Oguzturk, H.OBJECTIVE: We aimed to compare immunological, histological and oxidative effects of antiepileptic agents; felbamate and levetiracetam on head trauma in rats. MATERIALS AND METHODS: In this study, 32 Sprague-Dawley genus male rats were used. A closed head trauma mechanism was constituted in order to perform head trauma in rats. Rats were divided into 4 groups, and each group had 8 rats. Following head trauma, Group 1 (Control); normal saline was administered, Group 2; levetiracetam 50 mg/kg was administered, Group 3; felbamate 100 mg/kg was administered, and Group 4; levetiracetam 50 mg/kg and felbamate 100 mg/kg were administered with a combination. Injections were administered intraperitoneally once a day for 20 days. The rats were decapitated at the end of the 20th day. Blood and tissue samples were collected and analyzed for biochemical, immunohistochemical and histological parameters. RESULTS: Serum cytokine levels in Group 2, 3 and 4 were lower when compared to the control group. In Group 4, in which combined therapy was performed, cytokine levels were found to be the lowest. In Groups 2 and 3, a significant decrease in vascular congestion, mononuclear cell infiltration, hemorrhage, and neural degeneration was noticed in the pia mater. In Group 2, a decrease in vascular congestion and Purkinje cell degeneration was obtained in the cerebellum. However, the best outcomes were determined in Group 4. CONCLUSIONS: We determined that levetiracetam and felbamate alone are useful with respect to immunological, oxidative and histological alterations. However, their utility is better when used in a combination.Öğe Curcumin protects against testis-specific side effects of irinotecan(Verduci Publisher, 2021) Uyanik, O.; Gurbuz, S.; Ciftci, O.; Oguzturk, H.; Aydin, M.; Cetin, A.; Basak, N.OBJECTIVE: Irinotecan (IR/CPT-11) is a semisynthetic, water-soluble derivative of the alkaloid camptothecin. It is a topoisomerase I group antineoplastic drug commonly used for the treatment of many cancer types, although it has side effects in tissues such as the testis. Curcumin (CRC) is a polyphenol compound produced from the Indian saffron root; it is used as food colouring and food flavouring. This study examined the testis-specific side effects of IR and the ability of CRC to protect against these side effects. MATERIALS AND METHODS: Forty male Sprague-Dawley rats were used in our study (n = 10). The rats were randomly divided into the following four groups: control, IR, IR + CRC, and CRC. IR 10 mg/kg/day was administered intraperitoneally and CRC 100 mg/kg was administered orally. Blood and testicular samples were collected from rats in all four groups on day 30 after drug administration. Histological, biochemical, and spermatological analyses were conducted. RESULTS: Testis tissue and blood samples were collected from the four groups. Tissue samples from the control and CRC groups demonstrated normal histological appearance on light microscopy. The IR group exhibited the following findings: vascular congestion in the tunica albuginea layer; tubular degeneration and vascular congestion in the interstitial area; oedema, vacuolisation, and luminised cells in the seminiferous tubule: and cells that temporarily stopped dividing at any stage of division in the seminiferous tubule epithelium. In the IR+CRC group, histopathological damage was significantly reduced by CRC treatment. Biochemical analysis showed that the level of thiobarbituric acid reactive substance (TBARS) was significantly increased in the IR group, compared with the other groups. CRC treatment significantly decreased this IR-mediated increase in TBARS level, and the TBARS level in the IR + CRC group approached the level observed in the control group. IR treatment caused significant decreases in glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) levels. However, CRC administration tended to ameliorate the decreases in GSH, SOD, CAT, and GPx levels. CONCLUSIONS: In this study, IR had some toxic effects in rat testis tissue: these effects were ameliorated by CRC treatment. Further studies are warranted to confirm our results.Öğe Hesperidin protects testicular and spermatological damages induced by cisplatin in rats(Wiley, 2015) Kaya, K.; Ciftci, O.; Cetin, A.; Dogan, H.; Basak, N.The clinic usage of cisplatin, an anticancer drug, is limited due to it has many side effects in many systems and organs. In this context, it was aimed to investigate the protective effect of hesperidin, a citrus flavonoid, on testicular and spermatological damages induced by cisplatin in rats. The rats were randomly divided into four groups. The first group was kept as a control. In the second groups, cisplatin was given at the single dose of 7mgkg(-1) intraperitoneally. In the third group, hesperidin was orally administered at the dose of 50 mg/kgday(-1) for 14days. In the fourth group, cisplatin and hesperidin were given together at the same doses. Cisplatin treatment caused significant reductions enzymatic (SOD, CAT and GPx) and nonenzymatic (GSH) antioxidants and significant induction level of TBARS. In addition, cisplatin treatment caused decreased sperm motility, epididymal sperm concentration, increased abnormal sperm rate and histopathological damage. In contrast, hesperidin treatment significantly attenuated the harmful effects. In conclusion, this study clearly demonstrated that hesperidin has protective effects on cisplatin-induced reproductive system toxicity depending on its antioxidant properties. Thus, it is thought that hesperidin may be useful against cisplatin toxicity in patients with cancer in terms of reproductive system.Öğe Neuroprotective effects of hesperidin in a C57BL/6 mouse model of multiple sclerosis(Sage Publications Ltd, 2014) Ciftci, O.; Ozcan, C.; Kamisli, O.; Cetin, A.; Basak, N.; Aytac, B.[Abstract Not Available]Öğe Protective role of Diospyros lotus on cisplatin-induced changes in sperm characteristics, testicular damage and oxidative stress in rats(Wiley, 2016) Saral, S.; Ozcelik, E.; Cetin, A.; Saral, O.; Basak, N.; Aydin, M.; Ciftci, O.The aim of this study was to investigate the protective effect of Diospyros lotus (DL) on cisplatin (CP)-induced testicular damage in male rats. Twenty-eight male rats were randomly divided into four groups: group 1 - control, given isotonic saline solution; group 2 - CP 7mgkg(-1) given intraperitoneally as single dose; group 3 - DL 1000mgkg(-1) per day given orally for 10days; group 4 - CP and DL given together at the same doses. CP caused a significant increase in thiobarbituric acid-reactive substances (TBARS) level and a significant decrease in superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and glutathione (GSH) levels in rats testis tissues compared to the control group. CP caused a significant increase in lipid peroxidation in testis tissues compared to the control group, whereas DL led to a significant increase in SOD and GSH levels. However, there were no statistically significant changes in GPx and CAT levels. In addition, serum testosterone levels, sperm concentration and sperm motility were significantly decreased, but abnormal sperm rate and histological changes were increased with CP. However, these effects of CP on sperm parameters, histological changes and the tissue weights were eliminated by DL treatment. In conclusion, our study showed that the reproductive toxicity caused by CP may be prevented by DL treatment.Öğe Resveratrol prevents the experimental autoimmune encephalomyelitis (EAE) in C57BL/J6 mouse model(Sage Publications Ltd, 2016) Ciftci, O.; Ozcan, C.; Cetin, A.; Basak, N.; Kamisli, O.[Abstract Not Available]Öğe The useful effect of ?-glucan in a C57BL/J6 mouse model that has oxidative and neuronal damage caused by global cerebral ischemia/reperfusion(Wiley-Blackwell, 2016) Kaya, K.; Ciftci, O.; Oztanir, M.
