The Purpose of this study was to determine the serum content of LH, FSH and prolactin. Blood samples collected from day 20 prepartum to 20 postrtum in 8 sows. LH, FSH and prolactin were assayed by radioimmunoassay methods. LH levels increased from 2.3 mIU/$m\ell$ day 6 prepartum to 5.8 mIU/$m\ell$ by day +2 and remained quite constant thereafter. The mean serum FSH increased from 7.5mIU/$m\ell$ day 6 prepartum to 10.0 mIU/$m\ell$ at the time of parturition, but the difference in LH and FSH patterns reported here provide further evidence that the controlling mechanisms for the two gonadotropins are independent. Prolactin reached a peak mean level of 68.5ng/$m\ell$ at day 0.

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 experiment was conducted to determine the effect of FSH on in vitro maturation and in vitro fertilizing ability of oocytes recovered from normal follicles of different sizes in superovulated rabbits. Follicular oocytes recovered were cultured in modified Ham's F12 medium containing 0, 0.1, 1.0 and 10$\mu\textrm{g}$ FSH/ml for 18 hours and investigated the degree of cumulus cells expansion and nuclear maturation, which were fertilized with in vivo capacitated rabbit sperm. 1. The number of normal follicles<1.5mm, 1.6 to 2.5mm and> 2.5mm in diameter at 16 to 18hrs after HCG administration was 4.8 (38.8%), 5.5(45.4%) and 3.3(15.8%), respectively. Average percent of oocytes recovered was 69.7% and larger follicles tended to have a higher percent, recovery rate than smaller follicles. 2. The degree of cumulus expansion in medium containing 0.1$\mu\textrm{g}$ FSH/ml was similar to that of control, but markedly decreased under the level of above 1$\mu\textrm{g}$ FSH/ml. The proportions of oocytes which reached the second meiotic metaphase were 57.1, 61.5, 43.8 and 45.0% in medium containing 0, 0.1, 1.0 and 10$\mu\textrm{g}$ FSH/ml, respectively. Oocytes from larger follicles showed a higher nuclear maturation than that from smaller follicles. 3. In vitro fertilization rate of oocytes matured under 1$\mu\textrm{g}$ FSH/ml was slightly, not significant, higher than that of others. 4. Progesterone level in follicular fluid was about 67 to 71ng/ml with no difference in follicular sizes and estradiol-17$\beta$ level was under 25pg/ml.

The objective of this study was to investigate the responsiveness of hypophysis and gonads to synthetic GnRH among noncycling Murrah buffalo heifers at 24 months of age. The plasma FSH, LH, estradiol and progesterone levels were measured in blood samples collected at 1 hour before and upto 18th day subsequent to the administration of GnRH ($(200 {\mu}g)$) or saline (2 ml). The pretreatment levels of plasma FSH, LH estradiol and progesterone among GnRH treated heifers (N = 6) were $11.55{\pm}0.57ng/ml$, $0.68{\pm}0.06ng/ml$, $19.84{\pm}0.82pg/ml$ and $0.45{\pm}0.07ng/ml$ respectively. A quick elevation of FSH (p < 0.01) and LH (p < 0.05) within 5 min of GnRH administration was observed in all the heifers. The peak FSH ($74.97{\pm}18.63ng/ml$) and LH ($3.09{\pm}0.54ng/ml$) level was obtained at 30 min of GnRH administration. The elevated level of plasma estradiol on 5th to 18th day, FSH on 7th to 9th day (n = 3) and the progesterone on 13th to 18th day (n = 2) of GnRH injection was obtained. The study indicates that gonads of buffalo heifers at 24 months of age are responsive of GnRH induced gonadotropin release for folliculogenesis and luteal tissue formation

The objective of this study was to investigate the responsiveness of hypophysis and gonads to synthetic GnRH among prepubertal buffalo heifers at 12 months of age. Peripheral plasma FSH, LH, estradiol and progesterone level were measured in blood samples collected at 1 hr before and up to 18 days subsequent to the administration of $200{\mu}g$ GnRH (n=6) or saline (n=6) in Murrah buffalo heifers. The pretreatment peripheral plasma FSH, LH, estradiol and progesterone among GnRH treated heifers were $7.35{\pm}0.45ng/ml$, $1.08{\pm}0.3ng/ml$, $22.93{\pm}1.06pg/ml$ and $0.27{\pm}0.04ng/ml$ respectively. A quick elevation (p < 0.01) of FSH and LH within five min of GnRH administration was observed in all geifers. Although the peak FSH $(89.57{\pm}23.43ng/ml)$ and LH $(7.52{\pm}3.08ng/ml)$ reached by 10 min of GnRH administration, yet the animals differed both in terms of their amplitude response of FSH and LH release as well as in terms of time which animals took to exhiit maximum response to GnRH administration. The GnRH administration did not cause alteration in plasma estradiol and progesterone level. The present study suggests that the pituitary of 12 month buffalo heifers has capacity to synthesize and store of gonadotropin and have developed receptors for GnRH for a spike of gonadotropin release.

본 연구의 목적은 FSH 분비 조절에 있어서 각각 다른 progesterone (P) 농도가 Pulse 또는 Surge 형태의 분비 패턴에 어떤 영향을 미치는가를 탐구한다. 선행된 연구에서 LH surge는 난포기 (follicular phase)에서 보이는 P 농도에서만 발현되었고 황체기(luteal phase) 또는 아황체기(subluteal phase) P 농도에서는 완전히 억제되었다. 또한 LH pulse 분비는 황체기 P농도에서만 시간 의존적으로 감소되었으나 난포기 또는 아황체기 농도에서는 높은 빈도로 유지되었다. 즉 아황체기 P농도 (스트레스, 황체형성부전에서 발생)는 LH surge는 억제시키나 LH pulse 조절에는 아무런 영향을 마치지 않았다. 이 결과를 바탕으로 FSH surge 및 pulse 분비패턴을 알아보기 위해 난소가 제거된 Shiba 염소를 이용하여 인위적으로 난포기, 아황체기, 기능성황체기의 P 농도 및 estradiol(E) 농도를 유도하였다. 스테로이드 호르몬 농도의 변화를 알아보기 위해 매일 혈액을 채취하였으며, LH pulse 용 혈액은 10분 간격으로 8시간 동안 Day 0, Day 3, Day 7 (Day 0: P packet 이식 직전)에 연속채혈을 실시하고, LH surge 분비패턴은 Day 8에 16시간 estradiol를 3 ${\mu}g/h$ 농도로 주사하고, 52시간 동안 2시간 간격으로 채혈을 실시했다. 그 결과 유도된 P 농도는 염소의 정상적 발정주기에서 볼 수 있는 난포기(<0.1 ng/ml), 아황체기($1.1{\pm}0.1$ ng/ml), 황체기 ($3.3{\pm0.1}$ ng/ml) 수준의 농도로 유도되었다. FSH pulse 분비는 3그룹에서 모두 높은 빈도로 유지되었고, FSH surge는 LH surge와 같은 시간대에서 난포기 그룹에서만 확인되었다. 본 연구의 결과는 FSH pulse는 LH pulse에서 보이는 progesterone에 의한 억제 효과와 다르게 나타났으며, 이러한 결과는 FSH 분비 조절에 있어서 LH 분비와 다른 기전 및 요소들이 관여하는 것으로 판단되었다.

We assessed effects of ovine luteinizing hormone (oLH) and follicle-stimulating hormone (oFSH) on the granulose and theca layers from the four largest follicles, $F_1-F_4$ of hens which had been hypophysectomized 12 h before expected ovulation. Ovine LH (0.4 mg), oFSH (0.4 mg) or oLH in combination with oFSH (0.4 mg each) was injected intravenously 6 h after hypophysectomy. Progesterone, testosterone and $estradiol-17{\beta}$ levels of the granulose and theca layers which were removed 6 h after hormone injection, were measured by radioimmunoassay. Progesterone contents of $F_1-F_3$ granulosa layer at 12 h after hypophysectomy were much lower than those of control hens. This reduced progesterone level was restored partially by the injection of oLH alone for $F_1$, while no follicles responded to oFSH treatment. In contrast, the injection of oLH in combination with oFSH resulted in high progesterone content of the granulose layer from all four follicles. Progesterone content of the theca layer was negligible in all treatments. Simultaneous injection of oLH and oFSH also elevated $estradiol-17{\beta}$ level accumulating in the theca layer from all follicles, of which much higher concentrations of $estradiol-17{\beta}$ were observed when comparison were made to each of their corresponding controls. No appreciable change in testosterone contents of two layers was observed in the present experiments. These results suggest that oFSH augments function of oLH to stimulate the production of progesterone in the granulose layer and $estradiol-17{\beta}$ in the theca layer.

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.

In 105 patients with the past history of poor response to the previous controlled ovarian hyperstimulation(COH) due to poor follicular growth or premature LH surge, the effectiveness of pituitary suppression with gonadotropin-releasing hormone agonist(GnRH agonist) in IVF/GIFT program was evaluated in 112 cycles of COH using a combination regimen of Leuprolide acetate (Lupron TAP Pharmaceuticals, USA) and FSH/hMG or pure FSH from May to December, 1989 at SNUH. Starting on day 21 of the menstrual cycle(MCD #21, Day 1), Lupron (1.0mg/day, subcutaneous) was administered once a day till next MCD #3(suppression phase). After the confirmation of pituitary suppression, ovarian follicular growth was stimulated with FSH/hMG or pure FSH from MCD #3(Day + 1), and Lupron was continued with hMG or FSH until hCG administration (D 0) (stimulation phase). After suppression phase, serum E2 level decreased from 183.7${\pm}$95.1(Day 1) to 17.4${\pm}$12.3pg/ml (Day +1), and serum progesterone level from 19.17${\pm}$8.67 to 0.12${\pm}$0.05ng/ml. But there was no decresas in serum LH and FSH levels; LH from 12.74${\pm}$6.21 to 15.49${\pm}$4.93mIU/ml,FSH from 7.60${\pm}$3.84 to 8.58${\pm}$3.15 rnlU/ml. There was no occurrence of premature LH surge during COH. Eleven cycles(9.8%) were cancelled due to poor follicular growth during stimulation phase, and 3 cycles (3.0%) failed in the transvaginal oocytes fretrieval. Serum E2 level was 1366.8${\pm}$642.4 on D 0 and 1492.3${\pm}$906.9pg/ml on D+1. 7.00${\pm}$3.32 follicles(FD${\geq}$12mm) were observed on D 0, and 6.11${\pm}$4.15 oocytes were retrieved, with the oocyte retrieval rate per follicle of 95.0%. 3.59${\pm}$2.57 oocytes were fertilized and cleaved with the oocyte cleavage rate of 55.7%. In 83 IVF patients, 4.08${\pm}$2.39 embryos were transferred, and 16 pregnancies were obtained with the pregnancy rate per ET 2.39 mebryos were transferred, and 16 pregnancies were obtained with the pregnancy rate per ET of 19.3%. In 6 GIFT patients, 7.83${\pm}$3.31 oocytes were retrieved and transferred with maximum number of 6, but no pregnancy was obtained. When compared with the previous 108 cycles of COH using FSH/hMG or pure FSH regimen, the cancellation rate during COH was significantly decreased, and all the parameters of the outcome of COH including the pregnancy rate were increased. These data suggest that GnRH agonist therapy for pituitary suppression is an effective adjunct to the current gonadotropin regimens for COH in IVF/GIFT and can increase the probability of oocytes retrieval and pregnancy, especially in the previous poor responders.

Objective : To evaluate radiographic results of anterior fusion methods in two-level cervical disc disease : tricortical autograft and plate fixation (ACDF-AP), cage and plate fixation (ACDF-CP), stand-alone cage (ACDF-CA), and corpectomy and plate fixation (ACCF). Methods: The numbers of patients were 70 with a minimum 6 month follow-up (ACDF-AP : 12, ACDF-CP : 27, ACDF-CA : 15, and ACCF : 16). Dynamic simple X-ray and computed tomography were evaluated preoperatively, postoperatively, 6 month, and at the final follow-up. The fusion and subsidence rates at the final were determined, and global cervical lordosis (GCL), cervical range of motion, fused segment angle (FSA), and fused segment height (FSH) were analyzed. Results: Nonunion was observed in 4 (25%) patients with ACDF-CA, 1 (8%) patient with ACDF-AP, 1 (4%) patient with ACDF-CP. The number of loss of FSH (%) more than 3 mm were 2 patients (16%) in ACDF-AP, 3 patients (11%) in ACDF-CP, 5 patients (33%) in ACDF-CA, and 3 patients (20%) in ACCF. The GCL was decreased with ACDF-CA and increased with others. The FSA was increased with ACDF-AP, ACDF-CP, and ACCF, but ACDF-CA was decreased. At the final follow-up, the FSH was slightly decreased in ACDF-CP, ACDF-AP, and ACCF, but ACDF-CA was more decreased. Graft related complication were minimal. Screw loosening, plate fracture, cage subsidence and migration were not identified. Conclusion: ACDF-CP demonstrated a higher fusion rate and less minimal FSH loss than the other fusions in two-level cervical disc disease. The ACDF-AP and ACCF methods had a better outcome than the ACDF-CA with respect to GCL, FSA, and FSH.
