Association of serum and follicular fluid leptin and ghrelin levels with in vitro fertilization success
Objectives: The aim of this study was to evaluate the relationship between in vitro fertilization (IVF) cycle outcomes, serum and follicular fluid (FF) levels of leptin and ghrelin.
Material and methods: Forty-four women who underwent intracytoplasmic sperm injection cycles (ICSI) were enrolled in the study. On the third day (D3) of the menstrual cycle, venous blood samples were drawn for serum measurements of leptin and ghrelin. The follicular fluid (FF) and the corresponding oocyte were obtained from a single dominant preovulatory follicle at the time of oocyte pick-up. The FF and D3 serum leptin and ghrelin concentrations were measured by enzyme-linked immunosorbent assay. The relationship between pregnancy rate and serum, follicular fluid levels of leptin and ghrelin were analyzed.
Results: Of the 44 cases included, nineteen achieved clinical pregnancy (43.18%). Follicular fluid ghrelin levels were significantly lower in the pregnant group than non-pregnant group (p < 0.05) With respect to FF leptin, there was no statistically significant differences between the pregnant and non-pregnant women (p > 0.05). There was no statistically significant difference in D3 serum ghrelin between pregnant and non-pregnant groups (p > 0.05). However, D3 serum leptin levels were significantly lower in pregnant women than non-pregnant women (p < 0.05).
Conclusions: Lower ghrelin levels in the follicular fluid were associated with higher pregnancy rates. Also, D3 serum leptin levels were inversely correlated with clinical pregnancy rates. These findings support the potential role of these molecules on IVF outcomes
RUPTURED SPONTANEOUS HETEROTROPIC PREGNANCY
Introduction: Heterotropic pregnancy is a condition of the co-existence of different gestations. With the widespread use of assisted reproductive techniques its incidence is increasing
Is montelukast effective in regression of endometrial implants in an experimentally induced endometriosis model in rats?
Tapisiz, Omer/0000-0002-7128-8086WOS: 000348826200002PubMed: 25462212Objective: Montelukast, a selective antagonist of Type 1 cysteinyl leukotriene receptors (CysLT(1)Rs), antagonizes the proinflammatory and proasthmatic activities of CysLT(1)Rs. We investigated the effect of montelukast on a surgically induced endometriosis rat model. Study design: Thirty-two sexually mature, cycling, female Wistar-Albino rats, in which endometriotic implants were surgically induced, were randomly divided into three groups. Group I [Montelukast (M), 10 rats)] was given 1.6 mg/kg/day of oral montelukast sodium. Group II [Leuprolide acetate (L), 11 rats] was given 1 mg/kg single dose of s.c.leuprolide acetate. Group III [Control (C), 11 rats] received saline solution through an orogastric tube and served as controls. After a 3-weeks medication, the rats were sacrificed to investigate the endometriotic implants for size and morphological and histological characteristics, including immunoreactivity of MMP-2 and VEGF. Results: The mean area of implants decreased from 48.2 +/- 24.7 to 293 +/- 15.8 mm(2) in Group I (M) (P = 0.008) and from 62 +/- 32.1 to 39.9 +/- 18.1 mm(2) in Group II(L) (P = 0.003). In Group III (C), the mean area increased from 41.1 +/- 31.1 to 60.4 +/- 37.1 mm(2) (P = 0.025). Histopathological analysis showed statistically significant lower scores in rats treated with montelukast compared to leuprolide and controls. MMP H scores were not different between the groups in both epithelial and stromal MMP-2 immunostaining. VEGF H scores were statistically lower in Group I (M) in epithelial VEGF immunostaining when compared to Group II(L) and Group III (C) (P = 0.006). Conclusion(s): Montelukast may effectively cause a significant decrease in the area of endometriotic implants. (C) 2014 Elsevier Ireland Ltd. All rights reserved
Effect of the non-specific matrix metalloproteinase inhibitor Doxycycline on endometriotic implants in an experimental rat model.
The aim of this study was to investigate the possible therapeutic effects of Doxycycline (Dox) on endometriotic lesions in an experimental rat model. Thirty-seven female Wistar albino rats with surgically induced endometriosis were randomized and divided into four groups. The rats were administered 5 mg/kg/day oral Dox in Group 1 (low-dose Dox group, n=9), 20 mg/kg/day oral Dox in Group 2 (high-dose Dox group, n=10) and 1 mg/kg single dose, subcutaneous leuprolide acetate in Group 3 (leuprolide acetate group, n=9). The rats in Group 4 (control group, n=9) were given no medication. The rats received medication for three weeks and were then sacrificed to evaluate the morphological and histological features of the implants. Matrix metalloproteinase (MMP)-9 immunoreactivity of the implants was also evaluated. The size of the endometriotic implants decreased in Groups 1-3 but statistically significant differences were not observed among the groups. The mean surface area of the endometriotic implants decreased from 69.3±30.8 to 52.1±27.0 mm² in Group 1 (P>0.05), from 60.2±18.9 to 38.6±28.7 mm² in Group 2 (P>0.05) and from 58.1±33.1 to 26±9.0 mm² in Group 3 (P=0.03). The epithelial MMP-9 immunohistochemical score was significantly higher in Group 1 and lower in Group 3 when compared with the control group (Group 4) (P=0.042 and P=0.014, respectively). When the stromal MMP-9 immunohistochemical and histopathological scores of the endometriotic implants were compared, no statistically significant differences were found among the groups. Although there was no statistically significant difference, Dox reduced the endometriotic implant area in the rat endometriosis model. Further studies are required to investigate the potential efficacy of Dox in endometriosis due to its widespread use and tolerability

histopathological scores of the endometriotic implants were compared, no
statistically significant differences were found among the groups.
Although there was no statistically significant difference, Dox reduced
the endometriotic implant area in the rat endometriosis model. Further
