Purpose: The purpose of this study was to examine the effects of Koryo Hand Therapy (KHT) on menopausal symptoms and hormone levels (Follicle Stimulating Hormone [FSH], Luteinizing Hormone [LH], and estradiol [$E_2$]) in climacteric women. Methods: The research design was a nonequivalent control group pretest-posttest design. Data were collected from November 28, 2005 to February 28, 2006. The 45 participants were assigned to either the experimental group (23) or control group (22). KHT was applied three times a week, for a total of 8 weeks to the women in the experimental group. Results: There was a statistically significant decrease in menopausal symptoms (F=42.49, p=.000), FSH level (F=26.98, p=.000) and LH level (F=5.31, p=.026) between the experimental and control groups. There was an increase of the estradiol level in the experimental group but the difference between the two groups was not statistically significant. Conclusion: KHT can be applied as a supportive nursing intervention to climacteric women. KHT is expected to be a complementary alternative intervention for health management of the climacteric women.

To compare the stimulation effect of the ratio in follicle stimulating hormone and luteinizing hormone in induction of multiple follicular growth, the serum $E_2$ level, the diameter of follicle, number of aspirated follicles and cleavage rate of in vitro fertilized preovulatory oocytes as well as the pregnancy rate were evaluated. Forty one patients with irreparable tubal disease were stimulated by hMG(n=24) or FSH/hMG(n=17) for the purpose of in vitro fertilization and embryo transfer. The following results were obtained. 1. Serum estradiol($E_2$) levels on the day of hCG administration were $921.0{\pm}353.3\;pg/ml$ in hMG group and $1272.9{\pm}1060.6\;pg/ml$ in FSH/hMG group. The serum $E_2$ value of hMG group was significantly lower than that of FSH/hMG group. 2. The diameter of leading follicle by ultrasonogram on the day of hCG administration were $16.2{\pm}2.0\;mm$ in hMG group and $16.2{\pm}2.6\;mm$ in FSH/hMG group. No significant difference of follicle diameter between two groups was demonstrated. 3. The number of follicles with diameter above 10 mm by sonogram on the day of hCG injection were $3.91{\pm}2.32$ in hMG group and $6.52{\pm}3.86$ in FSH/hMG group. There was significant difference of number of follicles between two groups, (p< 0.01). 4. The number of oocytes found per patient at aspiration were $2.59{\pm}1.00$ in hMG group and 3. $76{\pm}2.31$ in FSH/hMG group. There was significant difference of number of aspirated oocytes between two groups. (p< 0.05). 5. The detection rate of preovulatory oocyte at aspiration were 68.4%(39/57) in hMG group (n=22) and 77.6%(38/49) in FSH/hMG group (n=13). 6. The cleavage rate of preovulatory oocyte at 44 hours after insemination were 74.4%(29/39) in hMG group(n=22) and 81.6%(31/38) in FSH/hMG group (n=13). When only hMG was used, one pregnancy was established in 15 patients to whom 29 zygotes were transferred. And a full term normal female baby was delivered by elective cesarean section. In the FSH/hMG group, five pregnancies out of 9 transferred patients were confirmed by serum ${\beta}-hCG$. Two pregnancies were spontaneously aborted before the 6th week of pregnancy. One patient aborted her baby at the 18th week of pregnancy because of incompetent internal os of the cervix. Two patients delivered two full term babies by elective cesarean section. From the above findings, paralell with the increase in the ratio of exogenous follicle stimulating hormone to luteinizing hormone, an increase in oocyte recovery was observed as well as an improvements in pregnancy rate. It was concluded that FSH enrichment early in the follicular phase had a beneficial effect in the controlled ovarian hyperstimulation.

While ornithine decarboxylase (ODC) is considered a key enzyme in the biosynthesis of polyamines, difluoromethylornithine(DFMO) acts as an inhibitor of polyamine synthesis. Cycling crossbred gilts were randomly assigned to one of two (treatment and control) groups (6/group). An indwelling silicone catheter was surgically implanted in the jugular vein of each animal. DFMO was dissolved in saline(200 mg/ml) and adminstered by i. m. injection at a dose of 80 mg/kg/day. The control group received an equivalent volume saline injection. DFMO was injected 3 times daily(08:00. 16:00. 24:00h) from day 16 of estrous cycle to 21 or until estrus. Once daily blood samples (10ml) were taken from day 14 until two days after the last DFMO treatment. Window blood samples were collected every 15 min for 8 h (from 08:00 to 16:00h) starting on day 16 and continuing until day 21 from one gilt per day. Serum progesterone (P$_4$), estradiol (E$_2$), LH and FSH were measured. Typical concentration profiles for P$_4$ and E$_2$ were seen during the follicular phase regardless of DFMO treatment. Injection of DFMO suppressed the preovulatory LH concentration in the serum(p<0.01) while having no effect on FSH profile. The present results indicate that DFMO had an inhibitory effect on LH secretion in the pig, but did not affect PI, E2 or FSH release.

Despite many efforts to improving canine in vitro maturation(IVM), the efficiency is still low compared to that of other mammalian species. The present study investigated the effects of gonadotropin, epidermal growth factor and cysteine supplementation on in vitro maturation of canine oocytes. Cumulus-oocyte complexes (COCs) were matured in basic medium (TCM-199 containing 10% FBS, 0.11mg/ml sodium pyruvate supplemented with or without $10{\mu}g/ml$ FSH, 10ng/ml EGF and 0.57mM cysteine) for 72 hr at $38.5^{\circ}C$ in humidified atmosphere of 5% $CO_2$ in air. After culture, oocytes were stained with Hoechst 33342 $(10{\mu}g/ml)$ for 30 min at $4^{\circ}C$, and assessed their nuclear status (GV: germinal vesicle, GVBD: germinal vesicle break down, MI: metaphasse I, MII: metaphase II, UK: unknown stage). No differences were observed in GV, MI and MII rate except GVBD rate between with and without gonadotropins addition respectively (6.7%, vs. 17.2%). Supplementation of 10ng/ml of EGF in hormones added IVM medium resulted in significantly (p<0.05) higher MII rate (4.54% vs.7.06%). Although there are no significantly difference, total of MI and MII rates were increased by adding cysteine. In conclusion, the present study indicates that supplementation of $10{\mu}g/ml$ LH and FSH, 10ng/ml EGF and 0.57mM cysteine in canine IVM medium show a positive influence on the progression of maturation to MII at 72 hr.

Objective: To assess the difference of baseline hormonal status and pathophysio logy, and confirm the risk factors for long term complication according to Body Mass Index in women with polycystic ovary syndrome. Materials and Methods: Serum level of LH, FSH, Estradiol, Prolactin, Testosterone, DHEA-S, fasting insulin were measured and 100 gm oral glucose tolerance test and endometrial biopsy were performed in total 75 chronic anovulation patients and 20 normal cycling infertility patients. 95 evaluated patients were divided into 3 groups including patients with chronic anovulation having BMI below 25, BMI beyond 25.1, normal cycling infertility patients, Group 1 (n=39), Group 2 (n=36), Group 3 (n=20), respectively. Statistical analysis was performed respect to relationship between BMI and measured hormone level, sum of glucose level during 100 gm OGTT, insulin resistance using t-test, ANOVA test, Post Hoc test, Mann-Whitney test. p<0.05 was considered as statistically significant. Results: Serum LH level and LH/FSH ratio was significantly higher in Group 1, compared than Group 2 or 3 (p<0.05), BMI and LH, LH/FSH ratio was negatively correlated (r=-0.351, r=-0.318). There was no significant difference according to BMI in FSH, testosterone, estradiol, prolactin, DHEA-S level. Fasting insulin and sum of glucose level during 100 gm OGTT were significantly higher in Group 2 compared than Group 1 or Group 3 (p<0.05), there was no significant difference between Group 1 and Group 3. Insulin resistance was more frequently identified in Group 2 compared than Group 1 (p=0.001). Conclusions: BMI and LH, LH/FSH ratio were negatively correlated, so clinical significance of LH, LH/FSH ratio in diagnosis of PCOS may be attenuated by increasing body weight. Overweight patients with chronic anovulation may be the risk group for developing insulin resistance, hyperinsulinemia, glucose intolerance, later type 2 DM. Hyperinsulinemia may operate mainly in overweight chronic anovulation patients in development of hyperandrogenism.

This study was designed to record the ovarian response towards a combined administration of heterologous buffalo FSH (buFSH) and LH (buLH) in goats. The impact of such a treatment on ovarian structures and on the plasma profile of the ovarian sex steroids (estradiol $17-{\beta}$ and progesterone) was studied. The buFSH and buLH were isolated from the buffalo pituitaries involving a procedure of ethanolic extraction, acetone precipitation followed by metaphosphoric acid - ammonium sulphate fractionation. Both gonadotrophin samples prepared were found biologically active and potent. There was an increase in the total number of follicles in the treated group ($12.66{\pm}1.24$) vis-a-vis the control group ($8.50{\pm}2.06$). However, the percentage ($51.48{\pm}6.37$) of large follicles were found reduced ($23.74{\pm}5.93$) following the treatment. Again the number of corpora lutea were observed significantly higher ($2.33{\pm}0.47C.L.$) in the treated group than (1 C. L.) in the control group. The peak plasma estradiol- $17{\beta}$ levels achieved, were much higher ($17.16{\pm}9.52pg/ml$) in the treated group, than the peak ($7.22{\pm}1.67pg/ml$) achieved in the control group. Similar trend was observed with respect to the progesterone levels (higher in the treated group). This study thus indicated that, a combined administration of heterologous buffalo FSH and LH to goats speeded up development of larger follicles nearing the ovulation stage. This population of the follicles subsequently got reduced and lead to the formation of the increased number of the corpora lutea observed in this study.

The present study investigated the effects of follicle stimulating hormone (FSH) and human chorionic gona-dotrophin (hCG) on the nuclear maturation of canine oocytes. Oocytes were recovered from mongrel female ovaries in various reproductive states; follicular, luteal or anestrous stage. Oocytes were cultured in sserum-free tissue culture medium (TCM)-199 supplemented with various concentrations of FSH (Exp. 1: 0, 0.5, 1.0 or 10 IU) or hCG (Exp.2:0, 0.5, 1.0 or 10 IU) or both (Exp. 3:1 IU FSH +1 IU hCG) for 72 hr to determine the effective concentration of these hormones, and to examine their combined effect. After maturation culture, oocytes were denuded in PBS containing 0.1% (w/v) hyaluronidase by gentle pipetting. The denuded oocytes were stained with $1.9\;{\mu}M$. Hoechst 33342 in glycerol and the nuclear state of oocytes was evaluated under UV light. More (p<0.05) oocytes matured to MII stage when follicular stage oocytes were supplemented with 1 IU FSH (6.2%) compared with the control, 0.1 or 10.0 IU FSH (0 to 1.2%). Significantly higher (p<0.05) maturation rate to MII stage was observed in follicular stage oocytes supplemented with 1.0 IU hCG (7.2%) compared with the control or other hCG supplemented groups (0 to 1.5%). However, the combination of FSH and hCG did not improve the nuclear maturation rate of canine oocyte (2.4 %) compared with FSH (6.2%) and hCG alone (7.2%). In conclusion, FSH or hCG alone significantly increased the maturation of canine oocytes to MII stage.

Purpose Precocious Puberty is defined as the development of secondary sexual characteristics in girls younger than 8 years, and boys 9 years. Cause premature closure of the epiphysis is a disease that eventually decreases the final adult height. In this study, we retrospectively analyzed to evaluate the diagnostic difference the GnRH (Gonado-tropin-releasing Hormone) stimulation test results with medical records of precocious puberty in girls. Materials and Methods From February 2015 to December 2015 it was enrolled in the girls 118 people who visited the Seoul National University Bundang Hospital, Pediatrics, Endocrinology Internal Medicine. True precocious puberty group (n=57), early puberty group (n=39), were divided into Premature thelarche (n=22) group. A Tanner stage, chronological age, bone age, height, body weight for each group was determined by examining the mean${\pm}$standard deviation. GnRH test result was compared LH (Basal, 30 min, 45 min, 60 min), FSH (Basal, 30 min, 60 min) for each group, Each group LH, FSH Peak value distribution, the mean${\pm}$standard deviation was calculated for the peak LH/LH basal ratio, peak LH/Peak FSH ratio. The significance probability (P-value) between the value of each third group was determined. Results The average height of the true precocious puberty group $131{\pm}14.85$, the mean weight was $28.80{\pm}4.93$, the average chronological age $7.1{\pm}0.81$, the mean bone age was $9.9{\pm}0.9$, The average height of early puberty group was $134{\pm}5.10$, the average weight $28.50{\pm}4.43$, the average chronological age $8.05{\pm}0.03$, the mean bone age was $10.0{\pm}0.62$, The average height of Premature thelarche $129{\pm}6,01$, the average weight was $28.65{\pm}5.98$, the average chronological age $7.02{\pm}0.58$, the mean bone age was $8.04{\pm}1.29$. There was no significant difference when compared to the height and weight. There was a significant difference between the groups in the chronologic age and bone age difference (P <0.0002) True precocious puberty group showed peak LH levels at 30'(82.5%), 45'(12.3%), 60'(5.3%), in Peak FSH 30'(8.8%), 60'(91.2%). Early Puberty group showed high values in Peak LH at 30'(79.5%), 45'(17.9%), 60'(2.6%), in peak FSH levels at 30'(7.7%), 60'(92.32%). In Premature thelarche Group it showed the Peak LH levels at 30'(30%), 45'(59%), 60'(9.09%), Peak FSH levels at 30'(0%) 60'(100%). When compared with the The Peak LH/basal LH ratio, True precocious puberty group was $19.09{\pm}17.15$, early puberty group was $15.23{\pm}10.88$, Premature thelarche group showed significant differences between the three groups as $4.93{\pm}4.36$.(P <0.0001) LH Peak/FSH Peak ratio, true precocious puberty group was $1.222{\pm}0.77$, early puberty group was $1.34{\pm}1.23$, Premature thelarche group showed significant differences between the three groups as $0.3{\pm}0.09$(P <0.0001) Conclusion In order to diagnose the true precocious puberty have a diagnostic value when the LH peak after GnRH stimulation is increased by more than two to three times compared to baseline or a predetermined level or more than 5~10 IU/L increases. GnRH Test is a test for a long time and the patient discomfort due to repeated blood sampling, but the hypothalamus-pituitary gland- gonad axis activity evaluate and is the most basic accurate test in the differential diagnosis of precocious puberty disorders.

This study was carried out to assess the effect of superovulation response and quality of embryos recovered from donor cows after a single subcutaneous injection of FSH dissolved in polyethylene glycol (PEG). Cows were allocated into control and 3 experimental treatment groups. In control, cows were injected intramuscularly 50 mg FSH twice daily for 4 days. Group 1 were injected subcutaneously with a single dose of 400 mg FSH dissolved in 30% PEG solution. Group 2 were injected subcutaneously with a single dose of 200 mg FSH dissolved in 30% PEG solution. Finally in group 3, cows were injected twice 200 mg FSH dissolved in 30% PEG solution by subcutaneous. Superovulation was initiated by injection of FSH between Day 8 and 14 of the estrus cycle (Day 0, the day of estrus), and followed by injection of 25 mg PGF$_2$$\alpha$ at 48 h after first FSH injection. Cows were then artificially inseminated (AI) with semen twice at 48 and 60 h after PGF$_2$$\alpha$ injection. At 7 days after the second AI, embryos collected non-surgically by flushing the uterine horns and were counted and compared morphologically as being transferable and degenerated among different superovulation treatments. Furthermore, progesterone and estradiol -17 $\beta$ in plasma were measured by radioimmunoassay following different treatments at given days All cows of treated groups were observed heat. but control group was showed 77.8%. Superovulation response was observed as 77.8, 87.5, 88.9, and 100% in control, Groups 1, 2 and 3 The mean number of corpus lutea (CL) detected in Group 1 were 19.6, which was, respectively significantly (P<0.05) higher than those of other groups (11.1, 13.4 and 7.6, respectively). However, there did not differ on the mean number of total embryos recovered and of transferable embryos between control and treated groups.
