Objectives: This study was designed to investigate the effects of Hyeolbuchukeotang( HCT) on the Estradiol Valerate(EV) induced Polycystic Ovaries and the Implantation of rats. Methods: PCO was induced by single intramuscular(IM) injection with EV in female rats. Normal group(n=8) were injected with sesame oil and orally administrated distilled water for 60 days. Control group(n=8) were injected with EV and orally administrated distilled water for 60 days. HCT treated group(n=8) were injected with EV and orally administrated HCT for 60 days. At the end day of experiment, we measured weights of body, ovaries, adrenal glands, uterus and contents of serum LH, FSH, ADD. The histomorphometrical changes of ovaries were also evaluated. And we observed the NGF and CRF expression by immunohistochemistry. Also we observed the mating and count the number of implantation. Results: - The weights(mg) of ovaries in HCT treated group($58.9{\pm}6.5$) were significantly increased (p<0.01) compared with control group ($42.3{\pm}8.5$). - The number of mature follicles in HCT treated group($9.8{\pm}2.6$) was significantly increased (p<0.01) compared with control group($6.1{\pm}2.1$). - The number of cystic follicles in HCT treated group($1.6{\pm}1.2$) was significantly decreased (p<0.01) compared with control group($3.8{\pm}1.5$). - The value of serum FSH(mIU/ml) in HCT treated group($3.870{\pm}2.151$) was significantly decreased(p<0.05) compared with control group($10.476{\pm}6.294$). - The expression of NGF-immunoreactive cells in the ovarian cells in HCT treated group was lesser observed than control group. - The number of implantation in HCT treated group($7.4{\pm}1.8$) was significantly increased (p<0.05) compared with control group($3.1{\pm}4.4$). Conclusions: Hyeolbuchukeo-tang(HCT) is effect on polycystic ovaries and the implantation of rats by EV-induced.
This study was conducted to compare the endocrine milieu, and pregnancy rates in In Vitro Fertilization and Embryo Transfer(IVF-ET) program employing combined with gonadotropin releasing hormone agonist(GnRH-a) and pergonal(LH 75lU+FSH 75lU) when either human chorionic gonadotropin(HCG) or progesterone were used for luteal phase support. A total number of 40 IVF-ET treatment cycles were prospectively studied. Ovarian hyperstimulation method was modified ultrashort protocol using GnRH-a. All patients started Decapeptyl at menstrual cycle day # 2, and HMG was started at # 3 days. When leading follicle was ${\geqq}$18mm or at least two follicles were ${\geqq}$14mm in diameter, HCG 10000lU intramuscularly was injected. After 36 hours HCG administration, oocytes were retrieved as usual guided by transvaginal ultrasound. Embryo were transfered 36-48 hours later. The patient's cycles were prospectively randomized to receive HCG(20cycles) or Progesterone (20cycles) for luteal support. The progesterone group received 25mg 1M starting from the day of ET. The HCG group received 1500IU 1M. on days 0, +2, +5 after ET. Estadiol($E_2$) and Progesterone($P_4$) were measured on the day of oocyte aspiration, ET day, and every 6 days thereafter. Results were follows as; 1. Estradiol, progesterone and LH levels on the day of HCG trigger, retrieved oocytes and number of transfered embryo were not significantly different in both groups. 2. On the day of aspiration and embryo transfered day, $E_2$, $P_4$ level were significantly higher in progesterone group than HCG group(p<0.01). 3. $E_2$, $P_4$ level on 6 days after ET were significantly higher in progesterone group than HCG group(p<0.01). But, $P_4/E_2$ ratio was not different in both groups. 4. $E_2$, $P_4$ level 12 days after ET were decreased abruptly in both groups and higher hormonal level appeared in HCG group(P<0.01). 5. The total pregnancy rate in the HCG group was 40% (8/20) and in the progesterone group 15%(3/20). 6. Comparing the pregnant and nonpregnant cases progesterone group was not different the hormonal status. In HCG group, pregnant cases appeared in higher $P_4$, $P_4/E_2$ ratio than nonpregnanct cases(P<0.01).
Previous studies showed that recombinant equine chorionic gonadotropin ($rec-eCG{\beta}/{\alpha}$) exhibits both follicle-stimulating hormone (FSH) and luteinizing hormone (LH)-like activities in rat LHR- and FSHR-expressing cells. In this study, we analyzed signal transduction by eelFSHR and eelLHR upon stimulation with $rec-eCG{\beta}/{\alpha}$ and native eCG. The cyclic adenosine monophosphate (cAMP) stimulation in CHO-K1 cells expressing eelLHR was determined upon exposure to different doses (0-1,450 ng/mL) of $rec-eCG{\beta}/{\alpha}$ and native eCG. The $EC_{50$ values of $rec-eCG{\beta}/{\alpha}$ and native eCG were 172.4 and 786.6 ng/mL, respectively. The activity of $rec-eCG{\beta}/{\alpha}$ was higher than that of native eCG. However, signal transduction in the CHO PathHunter Parental cells expressing eelFSHR was not enhanced by stimulation with both agonist $rec-eCG{\beta}/{\alpha}$ and native eCG. We concluded that $rec-eCG{\beta}/{\alpha}$ and native eCG were completely active in cells expressing eelLHR, similar to the activity in the mammalian cells expressing LHRs. However, $rec-eCG{\beta}/{\alpha}$ and native eCG did not invoke any signaling response in the cells expressing eelFSHR. These results suggest that eCG has a potent activity in cells expressing eelLHR. Thus, we also suggest that $rec-eCG{\beta}/{\alpha}$ can induce eel maturation by administering gonadotropic reagents (LH), such as salmon pituitary extract.
Objectives: The purpose of this study is to analysis the Clinical Study Trends on Korean Medicine Treatment for Polycystic Ovary Syndrome. Methods: The key words such as 'polycystic ovary syndrome', 'polycystic ovarian syndrome', 'korean medicine', 'herbal medicine', 'acupuncture' are used for the research through 'OASIS', 'KCI', 'KISS', 'RISS'. Results: Ten clinical studies with 73 patients were selected. All studies were the noncomparative studies, and 8 case reports, 1 case series, 1 retrospective chart review. Symptoms accompanied by PCOS were oligomenorrhea, amenorrhea, irregular menstruation, hirsutism, acne, obesity etc. The most used treatment was herbal medicine in all studies with 72 patients (98.6%). The most frequently used acupuncture and moxibustion point was respectively 合谷 (LI4) and 關元 (CV4). The duration of treatment was between 3 months and 10 months, the average 159 days. Outcome measurements were Recovery of menstrual cycle (97.6%), Hormone test (23.8%), Sonogram (61.9%), Indexes of obesity (23.8%). In terms of menstrual recovery, 35 patients (85.4%) have recovered from menstruation in 8 studies with 41 patients. In hormone tests, all 10 patients have decrease of LH/FSH ratio and LH in 3 studies with 10 patients. Through sonogram, Ovulation menstruation was confirmed in all 6 patients. In all 10 patients of 3 studies evaluating weight before and after treatment, weight was reduced. Conclusions: The effect on Korean Medicine treatment for Polycystic Ovary Syndrome had mostly positive results. However, Further large, well-designed clinical trials are needed to establish the foundation of Korean Medicine treatment for Polycystic Ovary Syndrome.

Objective: This study was aimed to investigate endometrial histology and to find predictable clinical factors for endometrial disease (hyperplasia or cancer) in women with polycystic ovary syndrome (PCOS). Methods: We investigated the endometrial histology and analyzed the relationship between endometrial histology and clinical parameters, such as LH, FSH, estradiol, testosterone, fasting and 2 hours postprandial glucose and insulin, insulin resistance, body mass index, endometrial thickness, menstrual status from 117 women with PCOS. Statistical analysis was performed with chi square and t-test, p-value<0.05 was considered as statistically significant. And receiver operating characteristic curve was used to find predictable clinical factors for endometrial disease and to decide the cuff off values. Results: In 117 women with PCOS, endometrial histologic profiles are as follows: proliferative phase in 90 women (76.9%), endometrial hyperplasia in 25 women (21.4%), and endometrial cancer in 2 women (1.7%). Of 25 women with endometrial hyperplasia, simple hyperplasia without atypia, complex hyperplasia without atypia and complex hyperplasia with atypia were diagnosed in 15 (12.8%), 6 (5.1%), 4 (3.4%) women, respectively. Age and endometrial thickness were significantly related with endometrial disease, p=0.013 and p=0.001, respectively. At the cut off level of 25.5 years in age, sensitivity and specificity predicting for endometrial disease were 70.4% and 55.6%, respectively (p=0.023). At the cut off level of 8.5 mm in endometrial thickness, sensitivity and specificity were 77.8% and 56.7%, respectively (p=0.000). Conclusion: In women with PCOS, the incidence of endometrial hyperplasia and cancer were 21.4% and 1.7%. The age and endometrial thickness may be used as clinical determining factors for endometrial biopsy.
In vitro development of bovine embryos is affected by many factors such as energy substrates, amino acids, and some growth factors. It has been reported that mRNA of insulin, PDGF and their receptors are detected in cow embryos, and that some chelating agents such as EDTA and transferrin have beneficial role on mouse and bovine embryos. The author hypothesized that insulin, transferrin arid PDGF added to a culture medium increase in vitro development of bovine embryos by chelating toxic substance(s) or increasing cell growth and metabolism. Immature oocytes from slaughtered ovaries of Holstein cows and heifers were matured for 24 hours in a TCM199 containing 10% fetal calf serum, FSH, LH and estradiol with granulosa cells in vitro. Matured oocytes were coincubated with sperm for 30 hours in a modified Tyrode's medium (IVF). Embryos cleaved to 2- to 4-cell at 30 hours after IVF were selected and cultured in a 30-$\mu$l drop of a synthetic oviduct fluid medium (SOFM) containing 0.8% BSA, Minimum Essential Medium essential and non-essential amino acids, and insulin, transferrin or PDGF for 9 days. Supplementation of a SOFM with insulin, and /or transferrin did not increase develop-mental rate to expanding and hatching blastocyst of 2- to 4-cell bovine embryos compared with control. The highest developmental rate to hatching blastocyst was shown when PDGF was added at the concentration of 10 ng /ml among the supplementing doses tested in the present study (p<0.05). Addition of PDGF without insulin to a SOFM could not increase embrye development, but combined addition of PDGF with insulin significantly increased (p<0.05) embryo development to hatching blastocyst (50%) compared with control (38%). In conclusion, insulin and PDGF supplemented to a SOFM may act synergistically and have beneficial effect on in vitro development of 2- to 4-cell bovine embryos matured and fertilized in vitro.
This study was designed to investigate the relationship between insulin resistance and obesity in the pathogenesis of polycystic ovarian syndrome(PCO). Twenty-two women with PCO, of whom thirteen were non-obese with body mass index(BMI, kg/$m^2$) of <25 and nine were obese with BMI${\geq}$25 were studied. Eight non-obese control women and seven obese control women were studied. Serum concentrations of testosterone, lutenizing hormone(LH)/follicle-stimulating hormone(FSH) ratio, and insulin-like growth factor I (IGF-I) were found to be significantly higher(P<0.05) in PCO women compared with control women, which clearly is not related to obesity. Serum glucose, insulin, and C-peptide levels were measured during a 2-hour oral glucose tolerance test(OGTT). Non-obese and obese women with PCO both(P<0.05) compared with control women demonstrated significant hyperinsulinemia after OGTT. The degree of hyperinsulinemia was found to be significantly higher in the obese women with PCO compared with the non-obese women with PCO. We concluded that obesity may contribute to hyperinsulinemia, however may not playa central role in the pathogenesis of PCO.
The nudear changes of bovine oocytes during 24 hrs. of culture for mejotic maturation were examined. Bovine oocytes were collected from small(<2 mm), medium(2~6 mm) and large(>6mm) follicles and classified into three grades by their morphological characteristics. A total of 242 oocytes collected were obtained:from 184 small, 157 medium and 1 large follicles, respectively and were classified into 95 grade I, 155 grade H and 92 grade III oocytes. All the bovine oocytes collected and graded were washed with a basal medium and incubated in groups of 10 for 24 hrs in 5% $CO_2$ and 39$^{\circ}C$. The basal medium used was composed of TCM-199 supplemented with sodium bicarbonate, sodium pyruvate, streptomycin, penicillin G and 10% FCS. The oocytes were cultured in drops of 50,$\mu$l basal medium supplemented with 35$\mu$g /ml FSH, 10$\mu$g /ml LH and 1$\mu$g /ml estradiol-17$\beta$. The oocytes were fixed and examined on their chromosomal status by 1% acetorcein staining in the interval of 3 hrs. Most of the grade I oocytes developed to germinal vesicule stage at 0 to 3 hrs., germinal vesicle breakdown at 6 hrs., metaphase I at 9 to 15 hrs., anaphase I and telophase I at 18 hrs., and metaphase II and the first polar body at 24 hrs. after culture for meiotic maturation. However, it was found that compared to grade I oocytes, grade H and W oocytes reached earlier to germinal vesicle breakdown and most of them developed earlier to M II stage at 21 hrs. after culture.
Objective: This study was performed to evaluate the effect of isoflavone supplementation on hormone levels, lipid profiles and total antioxidant status in patients with polycystic ovary syndrome. Methods: Total 11 women with polycystic ovary syndrome were supplemented daily with 150mg of isoflavone for 6 months. Blood samples were collected 0, 3, and 6 months after supplement of isoflavone for analysis of LH, FSH, E2, testosterone, free testosterone, SHBG levels, serum lipid profiles, and total antioxidant status (TAS). Results: After 6 months isoflavone supplementation, the hormone levels did not change significantly. Serum lipid profiles did not show any significant change in total cholesterol, LDL-cholesterol, triglyceride, lipoprotein(a), and free fatty acid levels. However, there was significant increase in HDL-cholesterol (p<0.05) for 3 months. Total antioxidant status was increased significantly after isoflavone supplementation for 6 months (p<0.05). Conclusion: Isoflavone supplementation showed positive effects on the HDL-cholesterol and total antioxidant status. it is implicated that isoflavone supplementation will may have a effect on cardiovascular disease in patients with polycystic ovary syndrome.
The ovaries of Korean native cows or heifers were obtained from a slaughter house and kept on 28~3O˚C and transported to laboratory within 2 hrs. The follicular oocytes were collected follicles. The oocytes were matured in vitro for 24 hrs. In TCM-199 supplemented with 35 $\pi$g /ml FSH, 10 $\pi$g /ml LH, 1 $\pi$g /ml estradiol-17 and granulosa cells at 39˚C under 5% $CO_2$ in air. The caudal epididymis of Korean native bulls were obtained from a slaughter house and transported to laboratory within 30 minutes. Swim-up of collected spermatozoa and freezing sperm was layered under 2ml fertilization B. 0. medium in two tissue culture tubes and held at a 45˚C angle for 0~2 hrs. They wrer fertilized in vitro by freezing sperm treated with heparin for 24 hrs, and then the zygotes were co-cultured in vitro with bovine oviductal epithelial cells for 7 to 9 days. The follicular oocytes recovered were classified into 41.7% as grade I, 51.5% as grade II and 6.8% as graed III. The number of oocytes recovered per ovary was averaged 8.3 and they were classifed into 2.3 as grade I, 2.5 as grade II and 2.3 as grade III. The cleavage rate of matured oocytes was significantly(P
