    Effect of ovarian stimulation with human menopausal gonadotropin and recombinant follicle stimulating hormone on the expression of integrins alpha(3), beta(1) in the rat endometrium during the implantation period
    (Elsevier Ireland Ltd, 2010) Sendag F.; Akdogan A.; Ozbilgin K.; Giray G.; Oztekin K.
    Objective: To investigate the effect of exogenous ovarian stimulation with human menopausal gonadotropin (hMG) and recombinant follicle stimulating hormone (rFSH) on the expression of integrins alpha(3), beta(1) in the rat endometrium during implantation. Study design: Following three successive normal estrous cycles the animals were divided into five groups: Group I (n = 10, control group) received no medication; Group II (n = 10) received 10 units of hMG; Group III (n = 10) received 20 units of hMG; Group IV (n = 10) received 10 units of rFSH; Group V (n = 10) received 20 units of rFSH at midday of middiestrous. The rats were then mated with fertile males. The animals were sacrificed on the day of implantation. The uterine horns were placed in fixative and paraffin blocks of the tissue were cut in 5 μm sections. The tissues were stained with primary antibodies; monoclonal anti-integrin alpha(3) and monoclonal anti-integrin beta(1) using immunohistochemical methods. The staining intensities of alpha(3) and beta(1) integrins were calculated separately for epithelium and stroma in each group. Results: Staining intensities of alpha(3) and beta(1) integrins in both the epithelium and the stroma were significantly lower in the treatment groups than the control group (p < 0.05). Conclusion: Ovarian stimulation by low and high doses of HMG and rFSH may have an effect on endometrial receptivity, possibly via a decrease in expression of integrins in the endometrium during the implantation period. © 2010 Elsevier Ireland Ltd.

    Evaluation of the surgical outcome and complications of total laparoscopic hysterectomy in patients with enlarged uteruses
    (Elsevier Ltd, 2016) Terzi H.; Hasdemir P.S.; Biler A.; Kale A.; Sendag F.
    Objective The aim of this study was to investigate whether uterine weight has a deleterious effect on the operation time, complication rates, length of hospital stay and incidence of intraoperative haemorrhage during total laparoscopic hysterectomy operation. Methods A total of 282 patients who underwent total laparoscopic hysterectomy for benign gynaecologic indications were retrospectively analyzed. The median operation time of 70 min was accepted as an index number, and a cut-off point of ≥300 g was calculated for uterine weight by using reciever operator characteristics (ROC) curve analysis. Results There was no statistically significant relationship between the uterine weight and haemoglobin drop rate (1.27 ± 0.89 vs 1.21 ± 0.88, p = 0.905), complication rate (10.83% vs 9.26%, p = 0.062) and length of hospital stay (3.27 ± 1.23 vs 3.37 ± 1.35 days, p = 0.505) based on this cut. Lee-Huang point was preferred for abdominal entry in cases with uteruses reached the level of umbilicus −2 cm in physical examination. Conclusions Uterine weight was not effected the complication rate, estimated blood loss and length of hospital stay in total laparoscopic hysterectomy operation. A cut-off value of 300 g could be used for an increased operation time. © 2016 IJS Publishing Group Ltd
