The insulin-like growth factor (IGF)s are believed to one of several growth factors that play an adjunctive role in ovarian follicular development. These factors circulate bound to a family of IGF-binding protein (IGFBP)s. It is known that circulating IGFBPs are involved in the transport of IGFs to tissues and modulate IGFs actions at local tissue. The purposes of this study were to evaluate changes in serum IGFBPs profiles during normal ovulatory menstrual cylce and to compare serum IGFBPs profiles in periovulatory phase of between normal ovulatory menstrual cylce and controlled hyperstimulated cycle. Fasting blood samples were obtained from 15 normal healthy women throughout normal ovulatory menstural cyle and on the day of aspiration of oocyte from 10 patients undergoing ovarian hyperstimuation for in vito fertilization-embryo transfer. Serum IGFBP-1 - IGFBP-4 were measured by western ligand blot and immunoprecipitation. Serum $17{\beta}$-estradiol was determined by radioimmunoassay. Type and molecular weight of serum IGFBP did not changed during normal ovulatory menstural cycle. No significant variation in the relative proportion and level of each IGFBP was found throughout normal ovulatory menstural cyle. Also, the relative proportion and level of each IGFBP did not correlated with serum $17{\beta}$-estradiol level. There was no significant difference in the relative proportion and level of each serum IGFBP between on the day of ovulation in normal ovulatory menstrual cylce and on the day of aspiration of oocyte in controlled hyperstimulated cycle. Our data indicate that IGFBPs have regulatory functions in ovary through an paracrine and autocrine rather than endocrine mechanism during normal ovulatory menstural cycle.

The purpose of this study is to evaluate the relationship of menstrual cycle and halitosis by measuring the concentrations of Voltile Sulfur Compounds, secretion rate of unstimulated saliva, secretion rate of stimulated saliva and viscosity of saliva during the menstrual cycle. The subjects were 19 female dental students of Yonsei University who had relatively good alignment of the teeth. They hadn't taken antibiotics or oral contraceptive pills during the few months prior to the experiment, and they didn't have any dental caries involving the pulp or periodontal disease. Lady-$Q^{(R)}$(Alpain Korea, Korea), which confirms the ovulation using saliva, was used to find out the menstrual cycle of subjects. Their history was taken and their basal body temperature was measured. On the basis of these data, the amount of Volatile Sulfur Compounds, secretion rate of unstimulated saliva, secretion rate of stimulated saliva, viscosity of saliva were measured during 1 day of the proliferative phase, 3 days of ovulatory phase and 1 day of the luteal phase within the menstrual cycle. The results were as follows : 1. The amount of Volatile Sulfur Compounds, secretion rate of unstimulated saliva, secretion rate of stimulated saliva, and viscosity of saliva showed no statistically significant cyclic change during proliferative phase, ovulatory phase, and luteal phase(p<0.05). 2. Between the secretion rate of unstimulated saliva and secretion rate of stimulated saliva, there was significant correlation during proliferative phase and luteal phase(p<0.05) and there was no significant correlation during ovulatory phase but relatively close result was seen. 3. The amount of Volatile Sulfur Compounds during proliferative phase and luteal phase had statistically significant correlation(p<0.05). 4. Secretion rate of stimulated saliva during proliferative phase and ovulatory phase, proliferative phase and luteal phase, ovulatory phase and luteal phase had significant correlations (p<0.01).

Objectives: The purpose of this study is to report the effect of Korean medical treatment in case of irregular menstruation (amenorrhea, oligomenorrhea) patients due to Polycystic ovarian syndrome (PCOS). There are some case reports about effectiveness of the Korean medical treatment to this disease, but cases are still deficient. And this case has significance for ascertaining PCOS patients' ovulation. Methods: 6 Amenorrhea or oligomenorrhea patients with PCOS were treated with Korean medical treatment (herbal medicine, moxibustion, acupuncture) at least 3 months. We estimated the effects of treatments through the change of menstrual pattern. Also, we checked follicles by ultrasonography for ovulation. Results: All patients recovered ovulatory menstrual cycle after taking Korean medical treatment for 3~9 months. Conclusions: These cases show the Korean medical treatment is effective on PCOS patients with irregular menstruation by recovering ovulatory menstrual cycle.

The ultrasonographic examination with vaginal probe(5MHz) was undertaken in 101 patients at infertility clinic of Eul-Ji General Hospital. This study was performed to evaluate the number of mature follicles per menstrual cycle, the relationship of both ovaries for consecutive ovulatory cycle and the responsiveness of follicular growth followed by administration of ovulation inductant. The results were as follows; 1. The ovulation induction group with clomiphene citrate showed more follicles than natural menstrual cycle group. 2. Each means of numbers of follicles between ovaries showed no difference between natural and ovulatory induction groups. 3. The rate of follicular growth per one menstrual cycle showed higher in the clomiphene citrate induced cycle group. 4. Clomiphene citrate induced group tends to be easier for multiple follicular growth but had no significant difference in statistics. 5. The ipsilateral Vs. contralateral follicular growth rate for consecutive menstrual cycles in both ovaries showed no significant difference between two groups.

Purpose: This study investigated the effects of sex hormones across menstrual cycle phases on knee muscle activity during one-leg landing in non-athletic females. Methods: Twenty-six healthy females who reported normal menstrual cycles for the previous three months were tested when estrogen levels were highest (ovulation) and lowest (menstruation). Knee muscle activity was analyzed based on electromyography (EMG) data recorded during landing on a 30-cm box. Before data collection, each subject was trained in single-leg landing tasks ten times. Landing was analyzed by measuring the average of three landing tasks. EMG data were collected between the moment of ground contact and the point of knee maximum flexion. The maximum voluntary isometric contraction (MVIC) for normalization that was recorded as the EMG root-mean-square (RMS) during landing was tested, with paired t-tests used to assess differences in knee muscle activity according to menstrual cycle phases. Results: The results showed that the soleus, semitendinosus, and lateral gastrocnemius muscle activity during landing was differed significantly during ovulation compared to that during menstruation (p<0.05). No significant differences in vastus medialis activity were found between menstrual and ovulatory phases during landing (p>0.05). Conclusion: Changes in the menstrual cycle in response to sex hormones changed the activity of muscles around the knee during landing. Females utilize different muscle activity control strategies during different phases of the menstrual cycle, which may contribute to increased ACL injury risk.

$^{18}F$-FDG PET/CT는 암세포에서 당 대사가 항진되는 현상을 이용하여 암환자의 진단에 폭넓게 사용 되고 있으며, 악성 종양에 대부분 섭취 되는 것이 일반적이지만, 정상 조직에도 섭취되는 경우도 있다. 이러한 현상은 보통 소화기계에서 빈번히 일어나며, 월경을 하는 가임기 여성에게서 자궁 주위에서의 섭취가 일어나기도 한다. 특히 가임기 여성은 월경에서 각 주기 동안 난소는 월경기, 증식기, 배란기, 분비기 이렇게 4단계의 주기를 거친다. 이러한 월경 주기에 따른 $^{18}F$-FDG 섭취는 영상에 다양한 영향이 미치기 때문에, 본 연구는 자궁의 $^{18}F$-FDG 섭취와 월경주기와의 관계를 알아보고자 하였다. 2008년 1월부터 2009년 3월까지 부인과 질환이 없고 월경이 규칙적인 $38{\pm}7.93$세 여성 환자 200명을 대상으로 하였다. 검사 전 6~8시간 금식 후 $^{18}F$-FDG 370 MBq를 정맥주사하고, 1시간 동안 충분한 휴식 후 전신 PET/CT 검사를 시행하였다. 영상 분석은 CT 영상으로 난소와 자궁의 위치를 정확히 파악한 후 같은 위상의 영상에서 표준화섭취계수를 측정하여 분석하였다. 월경주기에 따라 SUV의 변화가 크지는 않았지만, 분명 차이가 있었으며, 월경기 $SUV_{max}$는 $3.17{\pm}1.59$, $SUV_{avg}$는 $2.89{\pm}1.04$였고, 증식기 $SUV_{max}$는 $2.98{\pm}1.14$, $SUV_{avg}$는 $2.40{\pm}0.88$였다. 그리고 배란기 $SUV_{max}$는 $3.71{\pm}1.67$, $SUV_{avg}$는 $3.59{\pm}1.76$였고, 분비기 $SUV_{max}$는 $3.1{\pm}1.80$, $SUV_{avg}$는 $2.58{\pm}1.39$였다. 가임기 여성은 월경 주기에 따라 자궁과 난소에서 일정한 주기로 변화가 일어나며, 이에 따라 $^{18}F$-FDG PET/CT에서도 변화가 일어난다. 월경기, 증식기, 배란기, 분비기 이렇게 4단계의 주기를 가지고 영상에서 변화가 일어나므로, 검사 전 가임기 여성의 월경 주기를 파악하여 검사 시에 활용한다면, 자궁주변의 병변의 진단에 큰 도움이 될 것으로 사료된다.

35 patients of normal reproductive age group (22-37 yrs) were selected for ovulation induction using $Clomid^{(R)}$ and HMG. Correlation between canalization of cervical mucus and estradiol level in plasma. morphological ovarian follicular change by ultrasonogram, Ferning and Spinnbarkeit were studied in the induced ovulatory menstrual cycles. By retrospective analysis, the results were following; 1. Canalization appeared on the eighth day of the menstrual cycle in $Clomid^{(R)}$ group, and seventh day of HMG group. And the number of the channels increased gradually until the ovulation time. 2. The mean number of channels increased from 12${\pm}$12 in $Clomid^{(R)}$ group, 19${\pm}$14 in HMG group (Day-6) to a maximum of 46${\pm}$22 in $Clomid^{(R)}$ group (Day-1). 3. The maximum plasma estradiol(E2) level was 812${\pm}$722pg/ml in $Clomid^{(R)}$ group (Day-1), 1792${\pm}$504 pg/ml in HMG group (Day-1), and there was a good statistical correlation between the number of channels and the plasma E2 level. 4. The maximal follicular diameter was 19.4${\pm}$6.7 mm in $Clomid^{(R)}$ Group (Day-1) 19.3${\pm}$4.6mm in HMG group (Day-1) and after than decreased. There was a good statistical correlation between the number of channels and the follicular diameter. 5. When grade of ferning was I, the number of channels were 19.4${\pm}$6.7 in $Clomid^{(R)}$ group, 38${\pm}$26 in HMG group. When grade of ferning was III, the number of channels were 54${\pm}$30 in $Clomid^{(R)}$ group, 71${\pm}$36 in HMG group. 6. The maximum score of Spinnbarkeit was 2.6${\pm}$0.5 in Clomid group (Day-0), 2.6${\pm}$0.5 in HMG group (Day-2). In conclusion, the phenomenon of cervical mucus canalization showed the value of the clinical use as an ovulatin marker.

To evaluate the effectiveness of intrauterine insemination (IUI) in the treatment of infertility, timed-intercourse and intrauterine insemination by husband in stimulated cycles with clomiphene citrate and gonadotropins were compared in a total of 105 cycles. Patients received 100mg of clomiphene citrate daily for 5 days starting on day 3 of the menstrual cycle followed by hMG or FSH. Doses of exogenous gonadotropins were adjusted by the follicular development and concentrations of serum estradiol $(E_2)$. More than 3 follicles reaching >16 mm were present in the ovary, 5,000 IU of hCG was administered intramusculary. Patients received a maximum of three intercourse or IUI cycles for the treatment. Severe male (<$10{\times}10^6$ motile sperm) or age factor (>39 y) patients were excluded in this study. Pregnancy was classified as clinical if a gestational sac or fetal cardiac activity was seen on ultrasound. The overall clinical pregnancy rates were 17.1% per cycle (18/105) and 21.2% per patient (18/85). The pregnancy rates (per cycle) were 17.5% (11/63) in intercourse and 16.7% (7/42) in IUI groups, respectively. IUI had no significant improvement in pregnancy rate compared with timed-intercourse. The multiple pregnancy rates were 11.1% (1 twin and 1 triplet). No patient developed ovarian hyperstimulation. Abortion rate was 28.6% (2/7) in IUI group only. The delivery and ongoing pregnancy rates were 15.2% per cycle (16/105) and 18.8% per patient (16/85). There were no differences in age, duration of infertility, follicle size and level of estradiol $(E_2)$ on the day of hCG injection in pregnant and non-pregnant groups. However, total doses of gonadotropins were higher in pregnant group than in non-pregnant group (p<0.01). Pregnancy rate was not affected by ovulatory status at the time of insemination. These results indicate that well timed-intercourse in stimulated cycles is as effective as IUI for infertile couples.
