    Prevalence of Chlamydia pneumoniae specific antibodies in different clinical situations and healthy subjects in Izmir, Turkey
    (1998) Gencay M.; Dereli D.; Ertem E.; Serter D.; Puolakkainen M.; Saikku P.; Boydak B.; Dereli S.; Özbakkaloglu B.; Yorgancioglu A.; Tez E.
    Serological markers for Chlamydia pneumoniae were investigated by using the microimmunofluorescence (MIF) test in various age and patient groups in a specific area in Turkey. IgG seropositivity to C. pneumoniae was 64.3% and 18.7% in healthy adults and children, respectively. The highest positivity rate (77%) was in the 15-19 age group. Among the groups investigated, serological findings revealed a possible etiological association between C. pneumoniae and the clinical condition in the groups with acute myocardial infarction, atypical pneumoniae and chronic obstructive pulmonary disease.

    The aromatase inhibitor anastrozole is associated with favorable embryo development and implantation markers in mice ovarian stimulation cycles
    (2005) Karaer Ö.; Vatansever H.S.; Oruç S.; Özbilgin K.; Cilaker S.; Koyuncu M.F.
    Objective: To investigate the embryonic and endometrial effects of anastrozole in preimplantation and implantation phases in FSH-induced cycles in mice. Design: Blind randomized study. Setting: University research laboratory. Animal(s): Twenty-seven mature female mice. Intervention(s): Single-dose anastrozole (25 mg/kg [0.75 mg]), recombinant FSH (5 IU/mL), and hCG (5 IU/mL) (n = 9); recombinant FSH (5 IU/mL) and hCG (5 IU/mL) (n = 9); or sterile saline (1 mL) (n = 9). The morning of finding the vaginal plug was designated as day 1 of embryonic development (E1). Three mice from each group were sacrificed on E1 and embryos aspirated from uterine tubes. The rest of the mice were sacrificed on E2.5-3 and uteruses removed. Main Outcome Measure(s): Embryo quality, endometrial histologic evaluation, and immunohistochemical analysis of tumor necrosis factor-α, leukemia inhibitory factor, laminin, and collagen IV staining. Result(s): Anastrozole use in FSH-induced cycles not only caused an increase in preimplantation receptivity and implantation but also supported release of implantation markers. The enhanced embryo development seen in this study would explain the higher implantation because embryo development is synchronized with endometrial development. Conclusion(s): In mice, the use of anastrozole in FSH-induced cycles has a positive effect on embryo quality and implantation. This effect might be species dependent, and human studies are needed. ©2005 by American Society for Reproductive Medicine.
