    (De Gruyter Open Ltd, 2011) Abalı, Remzi; Bacanakgil, Besim Haluk; Çelik, Serdar; Aras, Özlem; Koca, Pelin; Boran, Birtan; Dursun, Nevra
    Objective: To investigate the correlation between cytology and cervical biopsy in patients with squamous cell abnormality on cervical cytology. Material and Method: The cervical smears diagnosed in our clinic between 2005-2008 were reviewed retrospectively. Cases which exhibited squamous cell abnormality (n: 374) were evaluated. Results: The mean age was 45.15 +/- 10.78. In the cytopathological results, 256 (68.4%) ASC-US, 21 (5.6%) ASC-H, 31 (8.2%) LSIL, 48 (12.8%) HSIL, and 8 (4.8%) invasive carcinomas were diagnosed. Histopathological results were 213 (57%) nonneoplastic, 85 (22.7%) CIN I, 14 (3.7%) CIN II, 34(9.0%) CIN III and 28 (7.5%) invasive squamous cell carcinomas. Including all squamous cell abnormalities, the sensitivity of the smear test in CIN I and higher grade lesions was 56.95% and the false positivity was 43.04%. Excluding ASC-US and ASC-H lesions, the sensitivity of the smear test was 77.31% and the false positivity was 22.68%. After evaluating cervical cyto-histopathological correlation, the positive predictive value was found to be 100% in invasive carcinoma, 62% in HSIL and 38% in LSIL. Conclusion: As the grade of cytopathological result increases, the correlation between biopsy and the smear test also increases. The high sensitivity of the cervical smear test for high-grade lesions shows that it is an effective screening test.

    The role of N-Acetylcysteine in preventing cyclophosphamide-induced gonadotoxicity: An experimental study in rats
    (Taylor & Francis Inc, 2016) Ünal, F.; Yüksel, M. Aytaç; Boran, Birtan; Yüksel, I. Temel; Abalı, Remzi
    This study assessed whether NAC could prevent cyclophosphamide (CY)-induced damage, by measuring the anti-Mullerian hormone (AMH) levels. Forty-eight Sprague-Dawley female rats were divided into four groups: CY + NAC, CY, NAC and control, each including 12 rats. There was no significant difference among the 24-h AMH values of the groups (p = 0.452), whereas a significant difference was found in terms of 72-h values (p = 0.003). Paired comparisons revealed no significant difference between CY and CY + NAC (p>0.699) and NAC (p = 0.065) groups regarding 72-h AMH values. However, AMH concentrations of the CY group at 72 hours were significantly lower than those of the control group (p = 0.015). AMH concentrations of the CY + NAC group at 72 hours were also significantly lower than those of the NAC group (p = 0.002) and the control group (p = 0.002). The AMH levels of CY and CY + NAC groups at 72 hours were significantly lower than those at 24 hours. The 24-h and 72-h AMH levels in the NAC and control groups were similar. In the present study, a single dose of NAC failed to prevent the cytotoxic effects of CY.
