Öğe DOES CABERGOLINE USING IN OHSS TREATMENT AFFECT ON IMPLANTATION INFLUENCING VEGF LEVELS IN ENDOMETRIUM OF RATS?(Elsevier Science Inc, 2015) Yilmaz, N.; Yilmaz, S.; Inal, H. A.; Timur, H.; Haltas, H.[Abstract Not Available]Öğe Protective effect of curcumin on ovarian reserve in a rat ischemia model: an experimental study(I R O G Canada, Inc, 2017) Eser, A.; Hizli, D.; Namuslu, M.; Haltas, H.; Kosus, N.; Kosus, A.; Kafali, H.Purpose of investigation: To determine the protective effect of curcumin on ovarian reserve in a rat ischemia model. Materials and Methods: Thirty female Albino rats were randomly divided into two groups by time of unilateral, left ovary ischemia/reperfusion (group 1: two-hour ischemia / two-hour reperfusion; group 2: four-hour ischemia / four-hour reperfusion). Each group was subdivided into three subgroups, sham, control, and curcumin (intraperitoneal curcumin (200 mg/kg) simultaneously with reperfusion). Histological grading of ischemic indices of paraffin-embedded ovarian tissue using hematoxylin and eosin (H&E), and anti-Mullerian hormone (AMH) levels by enzyme-linked immunosorbent assay (ELISA), were measured 40 days later. Results: No difference was found between groups 1 and 2 or among subgroups within either group for right and left ovary grades. AMH levels were significantly higher in the curcumin subgroup compared to sham and control within group 2 and in group 2 versus group 1 curcumin subgroups. Conclusion: Curcumin maintains and protects ovarian functions in an ischemia-reperfusion rat model.Öğe The effect of non-ionizing radiation on the ovarian reserves of female rats(Imr Press, 2017) Yuvaci, H. U.; Uysal, S.; Haltas, H.; Sirav, B.; Duvan, C. I.; Turhan, N.; Seyhan, N.Objective: The authors aimed to investigate whether there was any effect of 1800 MHz GSM-modulated radio frequency radiation (RFR) as a source of non-ionizing radiation on the ovarian reserves of female rats by hematoxylin eosin staining under a light microscope, and also to evaluate the effect on the anti-Mulllerian hormone (AMH) level of rats. Design: A prospective observational study. Materials and Methods: A total of 12 age-matched young adult female Wistar albino rats were divided into two groups. Group 1 (n=6) constituted the controls; group 2 (n=6) constituted the 1800 MHz exposed animals. RFR exposed group were kept ten cm away from the horn antenna to satisfy the near field condition. The control group was kept in the same setting without any RFR exposure. The exposure period was 20 minutes for five days/week for one month. Results: The results of this study showed that 1800 MHz RFR did not have a significant effect on the ratios of atretic follicles in rat ovary tissues when compared with the control group (p>0.05). However, the authors detected statistically significantly higher AMH levels in RFR exposed groups (p<0.005). Conclusions: 1800 MHz GSM modulated RFR exposure in rats was found to have no adverse effect on ovarian reserves or follicles. The present authors' failure to detect any changes could be due to the limited duration of the RFR exposure or the limited number of subjects used in the study. AMH levels were significantly higher, which might be due to the aforementioned limitations in this study. There is a need for further experimental studies in which the effects of RFR emitted by cellular phones can be studied.
