Öğe The combined effect of rosuvastatin and ischemic pre- or post-conditioning on myocardial ischemia-reperfusion injury in rat heart(Verduci Publisher, 2015) Kelle, I.; Akkoc, H.; Uyar, E.; Erdinc, M.; Evliyaoglu, O.; Saribas, S.; Tunik, S.OBJECTIVE: To investigate the combined effect of rosuvastatin and ischemic preconditioning or postconditioning on ischemia-reperfusion injury in in vivo rat heart. MATERIALS AND METHODS: Ninenty-six male adult Wistar rats were randomly assigned to eight groups: Sham group, ischemia-reperfusion, rosuvastatin preconditioning, rosuvastatin postconditioning, ischemic preconditioning, ischemic postconditioning, ischemic + pharmacologic preconditioning and ischemic + pharmacologic postconditioning groups. Blood samples were taken for creatine kinase evaluation at selected time points. Six rats in each group were separated for either infarct size assessment or immunohistochemical staining with Bcl-2 antibody. RESULTS: The staining with Bcl-2 was significantly lower in groups Sham, ischemic + pharmacologic preconditioning and ischemic + pharmacologic postconditioning groups which is well correlated with the decrease in infarct size for the same groups. The creatine kinase enzyme levels were also reduced to their lowest levels in ischemic + pharmacologic preconditioning and ischemic + pharmacologic postconditioning groups. CONCLUSIONS: These findings suggest that enriching the composition of reperfusate with rosuvastatin along with ischemic preconditioning or postconditioning procedures at the opposite sides of ischemia may interact synergistically for protecting ischemic myocardium from reperfusion injury. The combined application of rosuvastatin with ischemic preconditioning or ischemic postconditioning may provide a new therapeutic option in clinical interventions when compared to single treatment with ischemic and rosuvastatin preconditioning or postconditioning.Öğe EFFECTS OF ETHYL PYRUVATE ON TESTICULAR DAMAGE IN RATS WITH STREPTOZOTOCIN-INDUCED DIABETES(Editura Acad Romane, 2012) Akkoc, H.; Kelle, I.; Tunik, S.; Erdinc, M.; Erdinc, L.; Nergiz, Y.Diabetes mellitus is associated with impairment of testicular functions. Aim. The present study aimed to investigate the effects of ethyl pyruvate (EP) on the testicular tissue damage in rats with streptozotocin (STZ)-induced diabetes. Subjects and methods. Thirty-two Wistar albino male rats were assigned into four equal groups as follows: (1) control group (n:8); (2) EP-treated non-diabetic group (n:8); (3) diabetic group (n:8); and (4) EP-treated diabetic group (n:8). Rats with STZ-induced diabetes were kept alive for 14 weeks. After that, the EP solution was administered intraperitoneally to the rats in the EP-treated non-diabetic and diabetic groups at the dose of 50 mg/kg twice daily for 14 clays. At the end of this period, the left testes were removed from the rats for malondialdehyde (MDA) analysis, and the right testes were removed for histological examination. Results. As compared with the control group, the diabetic group had elevated MDA levels (210.9 +/- 12.7) and increased thickness of the basement membrane of the seminiferous tubules (3.01 +/- 0.16), but decreased tubular diameter (159 +/- 9.0) and Johnsen's score (5.31 +/- 0.1). In the EP-treated diabetic group, diabetes-induced impairment was significantly improved. Conclusion. These findings indicate that EP shows protective effects against diabetes-induced testicular dysfunction.Öğe The protective effects of allopurinol on glycerol-induced acute renal failure in rats(Blackwell Publishing, 2006) Erdinc, L.; Erdinc, M.[Abstract Not Available]Öğe Reduction of cisplatin-induced nephrotoxicity by L-arginine plus N-acetylcysteine(Blackwell Publishing, 2006) Erdinc, M.; Erdinc, L.[Abstract Not Available]
