Abstract
PURPOSE The leaves of Perilla frutescens var. acuta (PFA) are generally reported to have antioxidant, anti-allergic, anti-inflammatory, and antitumor effects and commonly used as a traditional medicine in East Asia. This study aimed to investigate the protective effect and antioxidant activity of PFA on busulfan-induced testicular dysfunction, histological damage, oxidative stress (OS), sperm quality, and hormone levels using a mouse model. MATERIALS AND METHODS C57BL/6 male mice were divided into four groups: control, busulfan-only treated, and varying concentrations of PFA (100 and 200 mg/kg) with busulfan. In the busulfan group, 40 mg/kg of busulfan was intraperitoneally injected to induce azoospermia. Mice were orally administered PFA for 35 consecutive days after busulfan administration. Samples were collected and assessed for testis/body weight, testicular histopathology, sperm quality, serum hormone levels, and OS to evaluate the effects of PFA treatment on spermatogenesis dysfunction induced by busulfan. RESULTS The busulfan-induced testicular dysfunction model showed reduced testis weight, adverse histological changes, significantly decreased sex hormones and sperm quality, and attenuated OS. These results indicate that PFA treatment significantly increased testis weight, testis/body weight, epididymal sperm count, motility, and testosterone level compared with busulfan alone. PFA treatment also attenuated the busulfan-induced histological changes. Furthermore, compared with mice treated with busulfan alone, PFA supplementation upregulated the testicular mRNA expression of the antioxidant enzymes superoxide dismutase 1 (Sod1) and glutathione peroxidase 1 (Gpx1), with a decrease in malondialdehyde (MDA) production and an increase in SOD and GPx activities. CONCLUSIONS This study shows that PFA exerts a protective effect against testicular damage by attenuating OS induced by busulfan. Our results suggest that PFA is a potentially relevant drug used to decrease the side effects induced by busulfan on testicular function and sperm during cancer chemotherapy.

Abstract
OBJECTIVE To evaluate the effects of various initiation time points and durations of hormone therapy (HT) on cardiovascular and metabolic parameters of premenarche, primary ovarian insufficiency (POI) mouse model, induced by 4-vinylcyclohexene diepoxide. METHODS A total of 50 mice at 4 weeks of age were developed into POI mouse model, further randomly categorized into 5 groups: control group without any intervention; no HT group with only high-fat diet (NT); group 1 with delayed estradiol treatment (T1); group 2 with on-time, continuous estradiol treatment (T2); and group 3 with on-time estradiol treatment but early stop (T3). Cardiovascular risk and metabolic parameters were measured. RESULTS Presenting with similar body weights, blood glucose levels of T1, T2, and T3 were all significantly lower than NT (p < .001). Serum total cholesterol and insulin were also significantly lower in all HT groups than in NT, especially in T2 (p < .001). For serum low-density lipoprotein-cholesterol, only T2 resulted in the statically lower level than those of NT, T1, and T3 (p < .001). Aortic thickness was significantly increased with aggravated fibrotic change of the intima in NT, and such consequence was significantly ameliorated in HT groups, mostly lowered in T2 (p < .05). Last, serum pro-inflammatory cytokines were significantly low in the HT groups than in NT, especially in T2 with the lowest level (p < .05). . CONCLUSIONS On-time, continuous E2 treatment immediately after a biologic estrogen deprivation event significantly reduced metabolic and cardiovascular risks in young, pre-menarche female mouse models of POI, confirming decreased serum levels of pro-inflammatory cytokines.

Abstract
Angiogenesis plays an essential role in various normal physiological processes, such as embryogenesis, tissue repair, and skin regeneration. Visfatin is a 52 kDa adipokine secreted by various tissues including adipocytes. It stimulates the expression of vascular endothelial growth factor (VEGF) and promotes angiogenesis. However, there are several issues in developing full-length visfatin as a therapeutic drug due to its high molecular weight. Therefore, the purpose of this study was to develop peptides, based on the active site of visfatin, with similar or superior angiogenic activity using computer simulation techniques.Initially, the active site domain (residues 181∼390) of visfatin was first truncated into small peptides using the overlapping technique. Subsequently, the 114 truncated small peptides were then subjected to molecular docking analysis using two docking programs (HADDOCK and GalaxyPepDock) to generate small peptides with the highest affinity for visfatin. Furthermore, molecular dynamics simulations (MD) were conducted to investigate the stability of the protein-ligand complexes by computing root mean square deviation (RSMD) and root mean square fluctuation(RMSF) plots for the visfatin-peptide complexes. Finally, peptides with the highest affinity were examined for angiogenic activities, such as cell migration, invasion, and tubule formation in human umbilical vein endothelial cells (HUVECs). Through the docking analysis of the 114 truncated peptides, we screened nine peptides with a high affinity for visfatin. Of these, we discovered two peptides (peptide-1: LEYKLHDFGY and peptide-2: EYKLHDFGYRGV) with the highest affinity for visfatin. In an in vitrostudy, these two peptides showed superior angiogenic activity compared to visfatin itself and stimulated mRNA expressions of visfatin and VEGF-A. These results show that the peptides generated by the protein-peptide docking simulation have a more efficient angiogenic activity than the original visfatin.

Abstract
BACKGROUND Several studies have shown that coenzyme Q10 (CoQ10) can rescue ovarian aging and that ovarian surface epithelium (OSE)-derived ovarian stem cells (OSCs) are useful for treating infertility due to ovarian aging. However, few studies have examined the effect of CoQ10 on OSCs. This study was aimed to investigate whether CoQ10 activates OSCs and recovers ovarian function in a 4-vinylcyclohexene diepoxide (VCD)-induced mouse model of ovarian failure. METHODS Forty female C57BL/6 mice aged 6 weeks were randomly divided into four groups (n = 10/group): a control group administered saline orally, a CoQ10 group administered 150 mg/kg/day of CoQ10 orally in 1 mL of saline daily for 14 days, a VCD group administered 160 mg/kg/day of VCD i.p. in 2.5 mL of saline/kg for 5 days, and a VCD + CoQ10 group administered VCD i.p. for 5 days injection and CoQ10 (150 mg/kg/day) orally for 14 days. After treatment, follicle counts were evaluated by hematoxylin and eosin (H&E) staining, and ovarian mRNA expressions of Bmp-15, Gdf-9, and c-Kit were examined by quantitative real-time PCR. Serum FSH, AMH, and ROS levels were also measured. Oocyte-like structure counts and the expressions of Oct-4 and MVH were also evaluated after culturing OSE for 3 weeks. In a second experiment, 32 female mice were administered CoQ10 as described above, induced to superovulate using PMSG and hCG, and mated. Numbers of zygotes and embryo development rate were examined. RESULTS Postcultured OSE showed significant increases in the numbers of oocyte-like structure and that the expression of Oct-4 and MVH were higher in the VCD + CoQ10 group than in the VCD group (p < 0.05). Numbers of surviving follicles from primordial to antral follicles, numbers of zygotes retrieved and embryo development rate to blastocyst were significantly greater in the VCD + CoQ10 group than in the VCD group (p < 0.01). Serum AMH level and ovarian expressions of Bmp-15, Gdf-9 and c-Kit were also significantly greater in the VCD + CoQ10 group than in the VCD group (p < 0.05). In contrast, serum ROS level was significantly lower in the VCD + CoQ10 group than in the VCD group (p < 0.05). CONCLUSION This study shows that CoQ10 stimulates the differentiation of OSE-derived OSCs and confirms that CoQ10 can reduce ROS levels and improve ovarian function and oocyte quality in mice with VCD-induced ovarian failure.

Abstract
Although ovarian aging is a key cause of decreased ovarian function and oocyte quality, it remains a problem in infertility treatment. Therefore, this study is aimed to investigate whether Paeonia lactiflora (PL), a herb improves ovarian function and oocyte quality using aged female mice. C57BL/6 female mice aged 8 months were treated orally every day with PL of 26.5 mg/kg (n=7) and 53 mg/kg (n=7) of body weight for 4 weeks using an oral zoned needle. The control group (n=7) was treated with normal saline. Ovaries and serum were collected for the H&E stain and the evaluation of reactive oxygen species (ROS) levels, respectively. In the second experiment, female mice were orally administered with PL (26.5 mg/kg: n=12, 53 mg/kg: n=12, control: n=12) and then superovulated with PMSG and hCG, and mated with male mice. Zygotes were retrieved and cultured for 4 days. Ovaries were provided for examination of expressions of genes associated with angiogenesis (VEGF and visfatin), anti-aging (Sirt1 and Sirt2), and follicular development (c-Kit, BMP-15, and GDF-9). PL significantly increased numbers of surviving follicles (primordial, primary, secondary, and antral), numbers of zygotes retrieved, embryo development rate, and ovarian expression of VEGF, visfatin, c-Kit, BMP-15, and GDF-9 at both doses. However, ovarian expression of Sirt1 and Sirt2 was increased at 53.0 mg/kg of PL. ROS levels were not affected by PL. These results suggest that PL may possess beneficial effects regarding ovarian function and oocyte quality, possibly by activation of ovarian angiogenesis and follicular development.

Abstract
IMPACT STATEMENT Ovarian aging is becoming a more important issue in terms of fertility preservation and infertility treatment. Serum anti-Mullerian hormone (AMH) level and antral follicle count (AFC) are being practically used as markers of ovarian aging as well as ovarian reserve in human. However, these factors have some drawbacks in assessing ovarian aging and reserve. Therefore, the identification of ovarian expressions of BMP15, GDF9, and C-KIT according to female could be applied as a potent predictor of ovarian aging. This work provides new information on the development of diagnosis and treatment strategy of age-related fertility decline and premature ovarian insufficiency.

Abstract
Human adipose-derived stem cells (hADSCs) have been implicated as a high potency source of chondrocytes in cell therapy for cartilage defects. However, appropriate stimulators for the chondrogenesis of hADSCs are needed. Oxysterols have the potential to act as a stimulator. This study aims to investigate the effect of oxysterols on the chondrogenesis of hADSCs. hADSCs were collected from the abdominal subcutaneous tissue samples of patients undergoing caesarean section, and were cultured to passage 5. Mesenchymal stem cell markers were examined by flow cytometry. After the cells were subjected to adipogenic, osteogenic, and chondrogenic induction, the differentiation of each cell lineage was evaluated by RT-PCR and specific staining (Oil red O, Alizarin red S, and Alcian blue, respectively). The cell pellets of hADSCs were cultured in chondrogenic induced media containing 2μM 22(R)-hydroxycholesterol, 22(S)-hydroxycholesterol, or 25-hydroxycholesterol for 4 weeks. At 3 and 4 weeks of culture, the size and wet weight of the pellets were measured. The expressions of chondrogenesis-related genes and glycosaminoglycans production were examined by quantitative real-time PCR and Alcian blue staining. hADSCs were positive for the mesenchymal markers CD75, CD90, and CD105, while being negative for the hematopoietic markers CD31, CD34 and CD45. The multilineage potential of hADSCs was confirmed by the expression of adipogenic-, osteogenic-, and chondrogenic-specific genes, along with specific staining. 22(R)-hydroxycholesterol treatment significantly increased the size and wet weight of the pellet, glycosaminoglycans production, and expression of chondrogenic-related genes compared to the control group and other oxysterols (P<0.05). These results indicate that 22(R)-hydroxycholesterol can be effective as a stimulator for the chondrogenesis of hADSCs.

Abstract
OBJECTIVE To investigate the effect of hydrogen-rich Korean Red Ginseng (KRG) water (HRGW) mixture on the spermatogenesis and sperm motility of mice of different ages. METHODS Eighty young (3 month-old) and aged (12 month-old) male mice were randomly assigned to 4 groups (n =10 per group) including control group, hydrogen-rich water (HRW) group (10 mL/kg daily), KRG group (50 mg/kg daily) and HRGW group (10 mL/kg and 50 mg/kg daily) by an oral zoned needle for 4 weeks. Sperm count and motility were measured using sperm suspension released from cauda epididymis. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and reactive oxygen species (ROS) in serum have also been estimated. Tubular changes were examined through histological hematoxylin and eosin staining. Expression of antioxidation (PPx3, PPx4, GSTm5 and GPx4), spermatogenesis (inhibin-a, neptin-2 and CREM), antiaging (SIRT1 and SIRT2), and angiogenesis [visfatin and vascular endothelial growth factor (VEGF)] related genes were examined through real-time polymerase chain reaction. RESULTS HRW and KRG treatment stimulated spermatogenesis followed by increasing sperm production and sperm motility (P <0.05). These effects were strengthened synergistically by a HRGW mixture (P <0.05 or P <0.01). HRGW greatly increased the expressions of antioxidation, antiaging, spermatogenesis related genes and VEGF especially in aged mice (P <0.05). Serum testosterone and FSH levels also increased, while serum ROS level decreased (all P <0.05). CONCLUSION HRGW increases sperm production and motility by enhancing antioxidation and stimulating spermatogenesis and sex hormone production, particularly in aged mice.

Abstract
Objectives This study was aimed to establish the most effective premature ovarian failure (POF) mouse model using Cyclophosphamide (CTX), busulfan (Bu), and cisplatin considering treatment duration of anticancer drugs and natural recovery time. Methods POF was induced by intraperitoneally injecting CTX (120 mg/kg)/Bu (12 mg/kg) for 1 to 4 weeks or cisplatin (2 mg/kg) for 3 to 14 days to C57BL/6 female mice aged 6 to 8 weeks. Controls were injected with equal volume of saline for the same periods. Body weight was measured every week, and ovarian and uterine weights were measured after the last injection of anticancer drug. To assess ovarian function, POF-induced mice were superovulated with pregnant mare serum gonadotropin and human chorionic gonadotropin, and then mated with male. After 18 hours, zygotes were retrieved and cultured for 4 days. Finally, the mice were left untreated for a period of times after the final injection of anticancer drug, and the time for natural recovery of ovarian function was evaluated. Results After 2 weeks of CTX/Bu injection, ovarian and uterine weights, and ovarian function were decreased sharply. Cisplatin treatment for 10 days resulted in a significant decrease in ovarian and uterine weight, and ovarian function. When POF was induced for at least 2 weeks for CTX/Bu and for at least 10 days for cisplatin, ovarian function did not recover naturally for 2 weeks and 1 week, respectively. Conclusions These results suggest that CTX/Bu should be treated for at least 2 weeks and cisplatin for at least 10 days to establish the most effective primary ovarian insufficiency mouse model.

Abstract
INTRODUCTION Women with infertility who have a poor ovarian responder (POR), characterized by a low number of retrieved oocytes after ovulation induction, often have a significantly reduced pregnancy rate after in vitro fertilization-embryo transfer (IVF-ET), due to the few transferred embryos. Acupuncture is a form of Korean Traditional Medicine. It involves the insertion of a microscopic needle at a specific point in the body, known as an acupuncture point or an acupoint. In this study, our purpose is to investigate how acupuncture affects the retrieval of mature oocytes after ovulation induction in patients with POR. METHODS AND ANALYSIS This study will be a randomized clinical trial comprising an IVF-ET trial and an IVF-ET trial after acupuncture. Seventy patients will by enrolled and randomly assigned to either of the 2 groups. The study subjects will be required to be diagnosed as having POR. Participants will be divided into 2 groups: IVF-ET single treatment group, and acupuncture and IVF-ET combined treatment group. The study subjects will be required to participate in a 15-week trial involving 16 acupuncture treatments over a period of approximately 2 months before ovulation induction for oocyte retrieval. The primary assessment of all participants will be comparing the number of oocytes. RESULT This treatment will be a therapeutic model for POR. DISCUSSION Our results will provide patients with POR as well as complementary and alternative medicine professionals, such as Korean medicine doctors, about the potential role of acupuncture in the treatment of POR. This will improve the quality of life in women with infertility and provide an important treatment option for patients with POR. Further studies can be performed to determine the optimal treatment for POR.

Abstract
Embryo implantation is the crucial step for a successful pregnancy. Diverse factors, including adhesion molecules, growth factors, and cytokines are important for embryo implantation through improving endometrial receptivity. Benzoic acid (BA), a component of various plants, has been shown to have antifungal and antioxidant effects. However, the effect of BA on embryo implantation remains unknown. Here, we showed the contribution of BA for the enhancement of endometrial receptivity through the leukemia inhibitory factor (LIF)-dependent increase of integrin αV, β3, and β5 expression. Furthermore, in vivo study using a mifepristone-induced implantation failure model showed that BA definitely improves the numbers of implantation embryos. Taken together, we suggest that BA has a novel function for embryo implantation through the up-regulation of LIF-mediated integrins, and may be a candidate for therapeutic medicine to increase the pregnancy rate.

Abstract
OBJECTIVES This study is aimed to introduce a simple neovaginoplasty procedure without significant complications using the spontaneous regenerative ability of labial and vestibular advancement flaps in patients with Müllerian agenesis. MATERIALS AND METHODS Prospectively collected data of 5 patients with vaginal agenesis due to Müllerian duct abnormality who underwent neovaginoplasty using labial and vestibular advancement flaps were retrospectively reviewed. Operative details, perioperative outcome, complications, length and width of the neovagina, and the postoperative sexual activity were evaluated. RESULTS The mean operation time was 48 min (range 30-60 min) and the duration of follow-up ranged from 7 to 50 months. The mean length of the neovagina was 9.6 cm × 3.5 cm and 10.8 cm × 3.5 cm at hospital discharge and at final follow-up, respectively. No significant complications occurred during or after surgery. Epithelialization was completed by 8-20 months and the time to first sexual intercourse ranged from 3 weeks to 27 months and none of the patients experienced any intercourse-related difficulties. CONCLUSION Our neovaginoplasty technique using labial and vestibular advancement flap is simple, safe, minimally invasive and effective while avoiding the morbidity associated with other grafting techniques.

Abstract
AIM This study was aimed to understand expressions of the visfatin, leptin, stromal cell derived factor (SDF)-1α, endothelial nitric oxide synthase (eNOS), and vascular endothelial growth factor (VEGF) in human uterine leiomyomas (UL) and normal myometrium. METHOD This study investigated expression of visfatin, leptin, SDF-1α, eNOS and VEGF in 23 uterine leiomyoma patients and 10 normal myometrium by RT-PCR and western blot. Messenger RNA transcripts of SDF-1α, eNOS, VEGF and hypoxia inducible factor-1α (HIF-1α) were analyzed according to the size of UL by real-time PCR. RESULTS There were no significant differences in expressions of visfatin and leptin between UL compared with normal myometrium. However, expressions of eNOS, SDF-1α and VEGF were significantly higher in both intramural and subserosal UL compared with normal myometrium. The expression of SDF1-α was significantly increased in small UL (<5 cm) compared to the large UL (≥5 cm), whereas the expressions of eNOS, VEGF and HIF-1α were higher in large UL than small UL. CONCLUSIONS This study shows that expression of SDF-1α, eNOS and VEGF were significantly higher in UL than myometrium with a different expression pattern according to the size of UL. However, expressions of visfatin and leptin had no significant differences between the two groups.

Abstract
Objectives Glucagon-like peptide-1 (GLP-1) is an intestinally secreted hormone and it plays an important role in the regulation of glucose homeostasis. However, the possible role of GLP-1 in the differentiation of adipose-derived stem cells (ADSCs) remains unknown. Therefore this study investigated the effect of GLP-1 on the differentiation of ADSCs into osteoblasts and adipocytes. Methods ADSCs were isolated from human adipose tissues of the abdomens, cultured and characterized by flow cytometry and multi-lineage potential assay. ADSCs were induced in osteogenic and adipogenic media treated with two different doses (10 and 100 nM) of GLP-1, and then the effect of GLP-1 on differentiation of ADSCs into osteoblast and adipocyte was examined. The signaling pathway involved in these processes was also examined. Results Isolated human ADSCs expressed mesenchymal stem cell (MSC) specific markers as well as GLP-1 receptor (GLP-1R) proteins. They also showed multiple-lineage potential of MSC. GLP-1 was upregulated the activity and mRNA expression of osteoblast-specific marker, alkaline phosphatase and the mineralization of calcium. In contrast, GLP-1 significantly suppressed the expression of adipocyte-specific markers, peroxisome proliferator-activated receptor gamma (PPAR-γ), lipoprotein lipase (LPL) and adipocyte protein 2 (AP2). This decreased expression of adipocyte specific markers caused by GLP-1 was significantly reversed by the treatment of extracellular signal-regulated kinase (ERK) inhibitor, PD98059 (P < 0.05). Conclusion This result demonstrates that GLP-1 stimulates osteoblast differentiation in ADSCs, whereas it inhibits adipocyte differentiation. The ERK signaling pathway seems to be involved in these differentiation processes mediated by GLP-1.

Abstract
OBJECTIVE This study aimed to examine the effect of laser-assisted zona thinning (LAZT) at one or four-points on the blastocyst formation and hatching process in mice with respect to female age. METHODS Eight-cell or morula embryos collected from superovulated C57BL female mice with different ages (6-11 and 28-31 weeks) were treated with LAZT at one-point (LAZT1) or four-points (LAZT4). The zona pellucida was thinned to more than 70% of its initial thickness by making two holes of 15-20 µm. RESULTS In the young mice, LAZT resulted in a significant increase in early hatching and hatching rates compared to the control group (p<0.05). However, in the old mice, LAZT significantly increased blastocyst formation as well as early hatching and hatching compared to the controls (p<0.05). These effects were more remarkable in LAZT4 than in LAZT1 and in aged mice than in young ones. CONCLUSION These results show that multi-point LAZT leads to a significant improvement of blastocyst formation and hatching in mice compared to controls.

Abstract
BACKGROUND Many studies have proposed that putative ovarian stem cells (OSCs) derived from the ovarian surface epithelium (OSE) layer of adult mammalian ovaries can produce oocytes. Few studies have reported that ovaries of aged mammalian females including mice and women possess rare premeiotic germ cells that can generate oocytes. However, no studies have reported the changes of OSCs according to the age of the female. Therefore, this study evaluated pluripotent and germ cell marker expression in the intact ovary, scraped OSE, and postcultured OSE according to age in female mice. METHODS C57BL/6 female mice of 2 age groups (6-8 and 28-31 weeks) were superovulated by injection with 5 IU equine chorionic gonadotropin (eCG). Both ovaries were removed after 48 hours and scrapped to obtain OSE. Gene expressions of pluripotent (Oct-4, Sox-2, Nanog) and germ cell markers (c-Kit, GDF-9, and VASA) were evaluated by RT-PCR. VASA and GDF-9 were immune-localized in oocyte-like structures. RESULTS Expressions of germ cell markers in the intact ovary were significantly decreased in aged females, whereas expressions of pluripotent markers were not detected, regardless of age. Scraped OSE expression of all pluripotent and germ cell markers, except for c-Kit, was similar between both age groups. Three weeks postcultured OSE had significantly decreased expression of GDF-9 and VASA , but not c-Kit, in old mice, as compared to young mice; however there was no difference in the expression of other genes. The number of positively stained Oct-4 by immunohistochemistry in postcultured OSE was 2.5 times higher in young mice than aged mice. Oocyte-like structure was spontaneously produced in postcultured OSE. However, while that of young mice revealed a prominent nucleus, zona pellucida-like structure and cytoplasmic organelles, these features were not observed in old mice. CONCLUSIONS These results show that aged female mice have putative OSCs in OSE, but their differentiation potential, as well as the number of OSCs differs from those of young mice.

Abstract
Human adipose-tissue-derived stromal cells (hADSCs) are abundant in adipose tissue and can differentiate into multi-lineage cell types, including adipocytes, osteoblasts, and chondrocytes. In order to define the optimal harvest site of adipose tissue harvest site, we solated hADSCs from different subcutaneous sites (upper abdomen, lower abdomen, and thigh) and compared their proliferation and potential to differentiate into adipocytes and osteoblasts. In addition, this study examined the effect of phorbol 12-myristate 13-acetate (PMA), a protein kinase C (PKC) activator, on proliferation and differentiation of hADSCs to adipocytes or osteoblasts. hADSCs isolated from different subcutaneous depots have a similar growth rate. Fluorescence-activated cell sorting (FACS) analysis showed that the expression levels of CD73 and CD90 were similar between hADSCs from abdomen and thigh regions. However, the expression of CD105 was lower in hADSCs from the thigh than in those from the abdomen. Although the adipogenic differentiation potential of hADSCs from both tissue regions was similar, the osteogenic differentiation potential of hADSCs from the thigh was greater than that of hADSCs from the abdomen. Phorbol 12-myristate 13-acetate (PMA) treatment increased osteogenic differentiation and suppressed adipogenic differentiation of all hADSCs without affecting their growth rate and the treatment of Go6983, a general inhibitor of protein kinase C (PKC) blocked the PMA effect. These findings indicate that the thigh region might be a suitable source of hADSCs for bone regeneration and that the PKC signaling pathway may be involved in the adipogenic and osteogenic differentiation of hADSCs.

Abstract
PURPOSE Surgery during pregnancy can be a cause of preterm labor or birth, possibly resulting from anesthetic agents or direct effects of surgery. This study was aimed to investigate the effect of propofol on uterine contractility by examining prostaglandin E2 (PGE2) production and the expression of PGE synthase 2 (PGES2) and cyclooxygenase-2 (COX-2) in amniotic membrane cells. METHODS Amniotic membranes were collected from healthy full-term women who underwent cesarean section at 37-40 weeks of gestation. The amniotic cells were cultured in α-modified-Eagle's medium with 10% fetal bovine serum for 24 h at 5% CO2 in a 37 °C incubator. Then, various doses of propofol (0.01-10 μg/ml) were used for treatment for 3 h. PGE2 concentrations in conditioned media were evaluated using ELISA. PGES2 and COX-2 expression were examined using RT-PCR and Western blot. Cell viability and apoptosis were examined by MTT, ATP assays, and the TUNEL method. RESULTS PGE2 production significantly decreased at 0.1 and 1.0 μg/ml propofol concentrations compared to controls. COX-2 and PGES2 mRNA expression was decreased in a dose-dependent manner with a significant difference at 0.1 μg/ml propofol compared to controls. The protein expression of COX-2 showed a similar result to mRNA expression, but protein expression of PGES2 was not significantly decreased. No effect of propofol was found in cell viability. CONCLUSIONS This study showed that propofol reduced the production of PGE2 and the expression of COX-2 and PGES2 without affecting cell viability.

Abstract
This study examined the expression of inhibitor of DNA-binding (Id) proteins and vascular endothelial growth factor (VEGF) in the ovary according to female age using a mice model as the first step in investigating the potential role of Ids and VEGF in ovarian aging. C57BL inbred female mice of three age groups (6-9, 14-16, and 23-26 weeks) were injected with 5 IU pregnant mare’s serum gonadotropin (PMSG) in order to synchronize the estrus cycle. After 48 h, ovarian expression of Ids and VEGF was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR), western blot and immunohistochemistry. Ovarian apoptosis was examined by ovarian expression of Bcl-2 and Bcl-xL. Expression of Id-1 and VEGF was decreased with advancing female age, but not Id-2, Id-3, and Id-4. In particular, their expressions were significantly decreased in aged mice of 23-26 weeks compared with the young mice of 6-9 weeks (p < 0.05). In contrast, ovarian apoptosis was greatly increased in the aged mice compared to the young mice. This result suggests that Id-1 may have an implicated role in ovarian aging by associating with VEGF.

Abstract
OBJECTIVE Ovarian angiogenesis plays an important role in folliculogenesis. However, little is known about the expression of angiogenic factors during follicular development according to female age. Stromal cell derived factor-1α (SDF-1α) plays a role in granulosa cell survival and embryo quality as an angiogenic chemokine. Leptin is also involved in folliculogenesis and angiogenesis. This study examined expression of SDF-1α and leptin, and their effects on the expression of angiogenic factors in the ovary during follicular development according to female age. METHODS Ovaries were collected from C57BL mice of two age groups (6-9 weeks and 24-26 weeks) at 6, 12, 24, and 48 hours after 5 IU pregnant mare's serum gonadotropin (PMSG) injection. The expression of ovarian SDF-1α and leptin mRNA was evaluated by RT-PCR. In the organ culture experiment, the ovaries were cultured in transwell permeable supports with Waymouth's medium treated with various doses of SDF-1α (50-200 ng/mL) or leptin (0.01-1 µg/mL) for 7 days. Then, mRNA expression of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), and visfatin were examined in the cultured ovaries. RESULTS Expression of SDF-1α and leptin in the ovary was significantly lower in the aged mouse group compared to the young mouse group (p<0.05). Expression of these two factors increased with follicular development after PMSG administration. SDF-1α treatment stimulated visfatin expression in a dose-dependent manner, while leptin treatment significantly increased eNOS expression. CONCLUSION These results suggest that decrease of ovarian SDF-1α and leptin expression may be associated with aging-related reduction of ovarian function. SDF-1α and leptin may play a role in follicular development by regulating the expression of angiogenic factors in mouse ovaries.

Abstract
OBJECTIVE We sought to report the safety and effectiveness of bleeding control using a large amount of highly diluted vasopressin in laparoscopic management of interstitial pregnancy. STUDY DESIGN This was an uncontrolled retrospective review of 20 patients who were laparoscopically treated for interstitial pregnancy using a large amount of highly diluted vasopressin. For hemostasis, 1 ampule of vasopressin was diluted in 1000 mL of normal saline (1000-fold) and 150-250 mL of diluted vasopressin was injected in the uterus below interstitial pregnancy. RESULTS Mean patient age and gestational age was 33.5 years and 6.7 weeks, respectively. Mean blood loss was 24 mL. The mean serum human chorionic gonadotropin level was 10,950, 4065, and 959 mIU/mL on the day of operation and postoperative days 1 and 4, respectively. CONCLUSION Laparoscopic management of interstitial pregnancy using a large amount of highly diluted vasopressin is safe and effective in hemostasis with minimal blood loss and no complications.

Abstract
OBJECTIVE To investigate a possible role of leptin contributing to the pathophysiology of Down's syndrome by assessing amniotic fluid leptin levels in the 2nd trimester of normal pregnancy and pregnancy complicated by Down's syndrome. METHODS We retrospectively assessed leptin levels of 2nd trimester amniotic fluid from 15 pregnancies diagnosed with Down's syndrome and 15 matched unaffected singleton pregnancies (controls). All amniotic fluid samples were obtained from women undergoing genetic amniocentesis at 16-20 weeks of gestation. Leptin levels were measured by enzyme-linked immunosorbent assay. RESULTS Amniotic fluid leptin levels were significantly decreased in the Down's syndrome group (3.26 +/- 2.36 ng/ml) compared to the controls (8.26 +/- 9.11 ng/ml, p < 0.05). CONCLUSION This study showed significantly decreased leptin levels in the 2nd trimester amniotic fluid of fetuses with Down's syndrome. This result suggests a possible role of leptin in the pathophysiology of Down's syndrome during the fetal period.

Abstract
OBJECTIVE To evaluate the effect of short coasting, by withdrawing both gonadotropins and gonadotropin-releasing hormone (GnRH) agonist, on the prevention of severe ovarian hyperstimulation syndrome (OHSS) without compromising pregnancy outcome. DESIGN Retrospective study. SETTING Large urban medical center. PATIENT(S) Forty-four women who had been coasted during controlled ovarian hyperstimulation (COH) for in vitro fertilization (IVF). INTERVENTION(S) When >or=20 follicles >15 mm with serum estradiol (E(2)) level of 4000 pg/mL were detected, both gonadotropins and GnRH agonist were withheld for 1 to 2 days. MAIN OUTCOME MEASURE(S) Changes of serum E(2) levels, number of oocytes retrieved, pregnancy rate. RESULT(S) The mean serum E(2) level fell from 7915 pg/mL at the onset of coasting to 3908 pg/mL on the day of human chorionic gonadotropin (hCG) administration. The mean number of oocytes retrieved and fertilization rate were 17.2% and 75.0%, respectively. Eighteen patients became pregnant (43.9%), and the implantation rate was 12.7%. Twenty-eight patients were coasted for 1 day, and 13 were coasted for 2 days. The mean decrease rate of serum E(2) level was 45.3% in 1-day coasting and 26.4% (first day) and 75.3% (second day) in 2-day coasting. The pregnancy outcome was similar between both groups. After coasting, three mild and two severe cases of OHSS occurred. CONCLUSION(S) Coasting for 1 or 2 days can be used successfully to prevent OHSS without compromising IVF cycle outcome.

Abstract
OBJECTIVE To investigate the relationship between follicular blood flow and the follicular fluid vascular endothelial growth factor (VEGF) and nitric oxide (NO) concentrations and to determine which factor might be a better predictor of the outcome of IVF-ET. DESIGN Prospective study. SETTING Academic research laboratory. PATIENT(S) Forty-seven cycles of IVF (tubal factor, 25 cycles; male factor, 22 cycles) at the infertility clinic of Pusan National University Hospital from February 2002 to June 2002. INTERVENTION(S) Follicular blood flow was estimated on the day of hCG administration. Each follicular fluid sample was collected at oocyte retrieval, and follicular fluid VEGF and NO concentrations were assessed. MAIN OUTCOME MEASURE(S) Follicular blood flow and follicular fluid VEGF and NO concentrations according to the age of patients, the cause of infertility, and pregnancy rate. RESULT(S) Of 47 cycles, 18 (38.3%) cycles resulted in a pregnancy. Follicular blood flow was significantly higher in the pregnant group compared with the nonpregnant group, but there was no statistically significant difference in age and infertility cause. Follicular fluid concentrations of VEGF and NO did not show statistically significant differences in age, infertility cause, or pregnancy outcome. As the follicle size increases, the follicular blood flow and follicular fluid VEGF concentrations increased significantly but the follicular fluid NO concentrations decreased. There was no correlation between VEGF and NO concentrations in the follicular fluid by linear regression analysis. CONCLUSION(S) Our study showed that follicular blood flow was positively associated with the outcome of pregnancy. This is the first study to investigate the direct association of the follicular blood flow with pregnancy outcome after IVF-ET. These results suggest that follicular blood flow might be a more effective prognostic marker of the pregnancy outcome of IVF than follicular fluid VEGF or NO concentrations.

Abstract
OBJECTIVE To examine the effect of beta-cyclodextrin piroxicam treatment for priming of the uterus on the pregnancy outcome of IVF-embryo transfer (ET) programs. DESIGN Prospective, randomized, double-blinded placebo-controlled clinical study. SETTING Large urban medical center. PATIENT(S) One hundred eighty-eight consecutive cycles of fresh IVF-ET and 78 cycles of frozen-thawed ET. The patients underwent IVF because of tubal, male infertility, unexplained, or endometriosis factors. They were randomly divided into treatment and control groups. INTERVENTION(S) In the treatment group, 94 cycles in fresh ET and 39 cycles in frozen-thawed ET the patients received an oral dose of 10 mg of piroxicam. In the control group, the same number cycles corresponding to the treatment group were treated with placebo. Both groups started piroxicam or placebo treatment 1-2 hours before ET. Patients and staff were blinded to the treatment. MAIN OUTCOME MEASURE(S) Implantation rate (IR) and pregnancy rate (PR). RESULT(S) Piroxicam increased significantly IR (18.7%) and PR (46.8%) compared to the control group (8.6% and 27.6%, respectively) in fresh cycles. With the exception of an unexplained factor, patients with the tubal, male infertility, or endometriosis factor had significantly higher PR in the treatment group compared to the control group. The beneficial effect of piroxicam was found in patients less than 40 years old, but was not found in patients more than 40 years. In frozen-thawed cycles, there were statistically significant differences between the treatment group and the control group in IR (9.4% vs. 2.3%) and PR (25.6% vs. 7.7%), respectively. CONCLUSION(S) Our study showed that piroxicam increases IR and PR after IVF-ET in both fresh and frozen-thawed ET cycles. The beneficial effect seems to be more remarkable in patients less than 40 years old with tubal, male infertility, or endometriosis factors. These results suggest that piroxicam treatment before ET is very effective in the priming of a uterus suitable for embryo implantation. This is the first study to investigate the possible consequence of piroxicam for improving the PR after IVF-ET.

Abstract
PURPOSE Our purpose was to establish an evaluation system for oocyte quality based on the incidence of cumulus cells apoptosis and to examine the effect of coculture, using autologous cumulus cells, on the outcome of IVF-ET according to proliferative activities of helper cells and the incidence of cumulus cells apoptosis. METHODS Cumulus cell masses were collected from 91 mature oocytes among 330 oocytes retrieved from a total of 34 IVF-ET cycles with tubal infertility and unexplained infertility. The incidence of apoptosis in cumulus cells was assessed by apoptosis detection kit fluorescein. On ovum pick up, 2nd day embryos were cocultured with autologous cumulus cells. Prior to coculture, in vitro proliferative activity of cumulus cells was evaluated. RESULTS Cumulus cells from patient groups over 40 years old had a significantly increased apoptosis incidence, a lower fertilization rate, and the decreased number of oocytes retrieved compared to the other age groups (P < .05). The incidence of cumulus cells apoptosis was significantly lower when the number of oocytes retrieved was 5 or less (P < .05). Cumulus cells from fertilized oocytes (0.43 +/- 0.07%) and those from patients who became pregnant (0.44 +/- 0.11%) following IVF-ET showed a significantly lower incidence of apoptosis compared to those of unfertilized oocytes (1.80 +/- 0.35%; P < .001) and the nonpregnant group (0.81 +/- 0.10%; P < .05). Embryo quality also had a negative correlation with the incidence of cumulus cells apoptosis. Coculture of fertilized oocytes with cumulus cells with high proliferative activity resulted in improved rates of implantation and pregnancy compared to that with poor active cumulus cells. No significant difference was found between the in vitro proliferative activity of cumulus cells and the incidence of cumulus cells apoptosis (P < .063). CONCLUSIONS The age of women might influence the incidence of apoptosis in cumulus cells, and the increased incidence of apoptosis is associated with the number of oocytes retrieved, the fertilization rate, and the pregnancy outcome following IVF-ET. These results suggest that the incidence of cumulus cells apoptosis can be used in predicting oocyte quality, outcome of IVF-ET, and age-related decline in fertility.

Abstract
OBJECTIVE To elucidate the mechanism for the mode of action of coculture by the use of a coculture system for mouse one-cell embryos with human oviductal epithelial cells. DESIGN Prospective, controlled in vitro experimental study. SETTING Academic research laboratory. ANIMAL(S) Female ICR strain mice aged between 6 and 8 weeks. INTERVENTION(S) Flushed one-cell embryos were cultured in human tubal fluid medium alone (control), in coculture system with human oviductal cells, in five kinds of conditioned media, and in a contactless coculture system using a cell-culture insert. MAIN OUTCOME MEASURE(S) The percentage of the embryos developed to hatching blastocyst stage and the level of superoxide anion in the supernatant from each culture condition. RESULT(S) The rates of embryo development to the hatching blastocyst stage were significantly higher in the coculture group (43%) than in the control group (none) (P <.05). The embryo development rate in the control group was similar to that of the embryos in the five kinds of conditioned media. The effects of coculture on embryo development disappeared in the contactless coculture group. The level of superoxide anion was significantly reduced in the coculture group compared to the control group. CONCLUSION(S) The present coculture system overcomes the two-cell block in vitro and improves the embryo development. The beneficial effect may be a result of direct cell-to-cell contact between the embryo and helper cells and the removal of deleterious components from medium, rather than a result of embryotrophic factors.

Abstract
PURPOSE Our objective was to explain a relationship between concentrations of tumor necrosis factor-alpha (TNF-alpha) and nitric oxide (NO) in follicular fluid, oocyte quality, and outcomes of in vitro fertilization--embryo transfer (IVF-ET). METHODS The concentrations of TNF-alpha and NO were measured in 115 follicular fluid samples collected from 43 patients undergoing IVF-ET program, due to tubal obstruction, some with endometriosis (8 patients) or hydrosalpinx (5 patients). A correlation of these factors concentrations and the oocyte quality, the oocyte maturity, and infertility-associated diseases was analyzed. RESULTS No correlation was found between concentrations of NO and TNF-alpha in follicular fluid. NO concentrations in follicular fluids were significantly higher in patients with endometriosis (P < 0.001) or hydrosalpinx (P < 0.01) compared to the patients with just tubal obstruction. Follicular NO concentration differences according to oocyte maturity and oocyte quality were not found. In contrast, TNF-alpha concentrations in follicular fluids were significantly higher in poor quality oocytes (P < 0.05) but were not associated with infertility-associated diseases, such as hydrosalphinx or endometriosis,and the oocyte maturity. No significant differences in follicular levels of NO and TNF-alpha as well as IVF-ET parameters of pregnant and nonpregnant groups were revealed. CONCLUSIONS There is no significant correlation between the concentrations of NO and TNF-alpha in follicular fluid. NO levels in follicular fluid are altered in infertility-associated diseases. However, TNF-alpha levels but not NO levels influence oocyte quality. These results suggest that the production of NO and TNF-alpha in follicular fluid may be regulated via different pathways and can be tempered with infertility-associated diseases, thereby influencing oocyte quality locally.

Abstract
PROBLEM Nitric oxide (NO) has been known to have multifunctional roles both in the male and female reproductive systems. We investigated the effects of sodium nitroprusside (SNP)-dependent NO release on sperm cell function and embryo development to elucidate the mechanisms of action of NO. METHOD OF STUDY Semen samples from 20 healthy men were processed by the swim-up method. Sperm motility, hyperactivation, and acrosome reaction were examined following incubation with various concentrations of SNP. The concentration of 10 nM to 1 mM was used for sperm motility and hyperactivation measurement and 1 microM to 1 mM for examining the effect on acrosome reaction. Embryo development to blastocyst stage was assessed using 100 nM to 1 mM of SNP added before transferring the mouse embryos into the culture medium. Finally, to understand the mechanism of action of NO, changes in embryo development were examined after zygotes were treated with various concentrations ranging up to 1 mM of 8-bromo-cGMP, an analog of cGMP. RESULTS Both sperm motility and hyperactivation were significantly reduced at 100 microM and 1 mM concentrations of SNP after 6 hr of incubation. After 24 hr of incubation, they were greatly decreased with all, except the 10 nM concentration of SNP. The percentage of acrosomal-reacted spermatozoa was increased with the increasing concentration of SNP following incubation with 10 microM and 1 mM of SNP. Embryo development was arrested since the two-cell embryonic stage with all except the 100 nM concentration of SNP, and inhibited by 200 microM of SNP regardless of SNP treatment stage. However, embryo development was not influenced by 8-bromo-cGMP. CONCLUSIONS We concluded that SNP-inhibited sperm cell function and embryo development in a dose- and time-dependent manner, and the inhibitory effect on embryo development, may not be a stage-specific treatment mediated via a cGMP-independent pathway. This result suggests that NO may be enough to affect the fecundity potential in vivo.
