Objective: The aim of the study was to investigate pregnancy, obstetric, and neonatal outcomes in women with small (<4 cm) unilateral endometriomas. Methods: This retrospective study included 177 patients: 91 patients with small endometriomas and 86 controls with unexplained or tubal factor infertility who were treated at the Süleymaniye Gynecology and Maternity Training and Research Hospital Infertility Unit between January 2010 and July 2015. The groups were matched with regards to demographic characteristics such as age, body mass index, and infertility duration. All of the women in this study conceived via intracytoplasmic sperm injection. We compared pregnancy, obstetric, and neonatal outcomes between these groups. Results: Women with endometriomas had a higher biochemical pregnancy rate, but lower clinical pregnancy and live birth rates than women with unexplained and tubal factor infertility (p<0.05 for all). However no significant differences were found in terms of obstetric and neonatal complications between the two groups (p>0.05 for all). Conclusion: In this study, we found that women with endometriomas less than 4 cm were more prone to early pregnancy complications. We also showed that this group did not have any increased risks of late pregnancy, obstetric, and neonatal complications.

Purpose: The purpose of this study was to investigate the anti-inflammatory effects of the water extract of Omisodokeum (OMSDE) on peritoneal macrophages, Methods: To verify the anti-inflammatory mechanism of OMSDE, the activation of nuclear $factor-{\kappa}B$ $(NF-{\kappa}B)$ and the phosphorylation of MAPK were examined. Results: The extract of OMSDE suppressed the production of LPS-induced nitric oxide (NO), tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-6 and IL-12 in the macrophages. OMSDE inhibited the degradation of inhibitory ${\kappa}B-{\alpha}$ $(I{\kappa}B-{\alpha})$ and it suppressed the activation of extracellular signal-regulated kinase (ERK 1/2) but didn't inhibit c-Jun N-terminal kinase (JNK) and p38, indicating that OMSDE may inhibit the pro-inflammatory cytokine production process by inhibiting the activation of $NF-{\kappa}B$ and ERK 1/2. Furthermore, OMSDE inhibited the production of interferon $(IFN)-{\beta}$ but didn't inhibit of $IFN-{\alpha}$ in the LPS-stimulated macrophages through the down-regulation of interferon regulatory factor (IRF)-1 and IRF-7. The Oral administration of OMSDE inhibited LPS-induced endotoxin shock and the production of $TNF-{\alpha}$ in serum but didn't inhibit of $IL-1{\beta}$ and IL-6. Conclusion: These results suggest that OMSDE may be effective in the prevention and treatment of inflammatory diseases.

Platelet activating factor(PAF) has been reported to play a significant role in ovulation, establishment and maintnance of early pregnancy. The object of this study was to investigate the influence of PAF on progesterone secretion in rabbit by measurement of pheripheral blood concentration of progesterone. PAF had no effect on progesterone secretion and did not induce decidual reaction in nonovulatory rabbit. But 8th day of hCG induced pesudopregnant rabbit, PAF significantly increase progesterone secretion. Progesterone level was significantly increased at 0.5 and 4 hours after treatment with $10^{-8}$ M PAF on days 2, 4, 6, 8 of gestation as compared than those treated with normal saline. When PAF was injected 2 days after coitus, progesterone levels on days 4, 6, 10, 14 of gestation was significantly increased than those with saline injected group. These results suggest that PAF increase progesterone secretion from the hCG-primed ovary and during pregnancy in rabbit.

Objectives: The purpose of this study was to investigate the anti-inflammatory effects of aqueous extract from Cicadidae Periostracum(CP) on the RAW 264.7 cells. Method: We examined the cytokine productions including nitric oxide(NO), interleukin(IL)-1b, IL-6 and tumor necrosis factor-a(TNF-a) in lipopolysaccharide (LPS)-induced RAW 264.7 cells and also inhibitory mechanisms such as mitogen -activated protein kinases(MAPKs) and nuclear factor kappa BNF-kB) using Western blot. Results: CP inhibited LPS-induced production of NO, IL-1b and TNF-a but not of IL-6 in RAW 264.7 cells. CP respectively inhibited the activation of MAPKs such as extracelluar signal-regulated kinase(ERK 1/2), c-Jun $NH_2$-terminal kinase(JNK), p38 and NF-kB in the LPS-stimulated RAW 264.7 cells. Also oral administration of CP inhibited CLP - induced endotoxin shock. Conclusion: our results showed that CP down-regulated LPS-induced NO, IL-1b and TNF-a productions mainly through ERK, JNK, p38 MAPK and NF-kB pathway, which suggest the anti-inflammatory effects of CP.

Objectives: This study was designed to investigate the effects of PR on ovarian tissue in PCOS rats through measurement of morphological and histo-pathological observations, ovarian size. In addition, effects on expression levels of Insulin like Growth Factor Receptor(IGFR) were also investigated to elucidate related mechanisms. Methods: PCOS was induced by single intermuscular injection with ${\beta}$-Estradiol 17-Valerate(EV) in female rats. Normal group(NOR, n=8) were injected with sesame oil and administrated hard food for five weeks. Control group(CTL, n=8) were injected with EV and administrated hard food for five weeks. CR group(n=8) were injected with EV and administrated hard food mixed CR for five weeks. Then, we measured weights of body and ovary, uptakes of food and water. And we observed morphological and histo-pathological changes of ovary, levels of IGFR. Results: In this experiments, single injection of Estradiol Valerate(EV) induced suppression of weight gain, formation of cysts, increase of IGFR expression. Oral administration of PR prevent decrease of ovarian size significantly. Further more, formation of cystic follicles induced by EV injection is suppressed by PR treatment. Conclusions: These results suggest PR can be used for patients with PCOS to prevent formation of cystic follicles and malfunction of ovary.

Objective: This study examines whether maternal group B Streptococcus (Streptococcus agalactiae, GBS) infection was associated with preterm births and premature neonatal outcomes. Methods: Maternal and neonatal outcomes were examined among singleton pregnant women with preterm birth (from $24^{+0}weeks$ to $36^{+6}weeks$) who were tested for GBS (n=203) during the pregnancy. Data were collected retrospectively from the medical records of women who delivered at our hospital from January 2015 to February 2017. We compared obstetrical factors (causes of preterm birth) and neonatal (gestational age at delivery, birth weight, Apgar score 1 min/5 min, hospitalization period, duration of mechanical ventilation, neonatal C-reactive protein within three days, and other complication [respiratory distress syndrome, neonatal deaths]) outcomes between GBS-infected and non-infected pregnant women. Results: There were 203 singleton pregnant women included in the study, 25 of whom were confirmed to have a GBS infection during the pregnancy. There was no difference in neonatal outcomes by GBS status. Preterm premature rupture of membranes (pPROM), as an obstetric factor, was associated with GBS infection (P=0.022). GBS infection raised the risk of pPROM by 3.6 times (odds ratio 3.648, 95% confidence interval 1.476-9.016, P=0.005). Conclusion: GBS infection in preterm birth was associated with pPROM but did not result in adverse neonatal outcomes. Continuous attention and evaluation of GBS infection, a major cause of neonatal sepsis and pneumonia, are needed.

Purpose: This study was performed to determine anti-imflammatory effects of Haedoksamultang. Methods: In this study, I examined the effects of Haedoksamultang on the production of nitric oxide(NO), tumor necrosis factor-${\alpha}$(TNF-${\alpha}$), and interlukin-1${\beta}$(IL-1${\beta}$) as well as the expression of inducible NO synthase(iNOS), cyclooxygenase-2(COX-2), TNF-${\alpha}$, and IL-1${\beta}$ in RAW 264.7 cells. Haedoksamultang inhibited LPS-stimulated NO production. Western blotting and RT-PCR analysis showed that Haedoksamultang suppressed LPS-induced iNOS and COX-2 protein and mRNA expression in RAW 264.7 cells. Haedoksamultang also suppressed the expression and production of LPS-stimulated TNF-${\alpha}$ and IL-1${\beta}$ in RAW 264.7 cells. Haedoksamultang inhibited NF-${\kappa}B$ activation in LPS-treated RAW 264.7 cells. Moreover, this compound blocked $I{\kappa}B-{\alpha}$ phosphorylation and nuclear translocation of the cytosolic NF-${\kappa}B$ p65 subunit, which highly correlated with the production and expression of inflammatory mediators. Results: Haedoksamultang suppresses that inflammation-associated gene expression by blocking NF-${\kappa}B$ activation. Conclusion: These results suggest that Haedoksamultang may be beneficial for treating inflammatory disease.
