The present study was accomplished to investigate the relation between menstrual cycle and ovulation by studying the fluctuation of FSH, LH, estrogen and progesterone concentration in serum samples of selected senior high school women with normal and delayed menstrual cycles after administration of Jokyungijongoktang which was a widely used herb medicine for controlling abnormal menstrual cycles. The obtained results were summarized as follows : 1. There was a significant increase of FSH concentration in women with delayed menstrual cycles after administration of Jokyungjongoktang during the preovulatory phase. 2. Jokyungiongoktang produced a significant elevation od LH concentration in women with normal and delayed menstrual cycles, respectively, during the critical interval of ovulation. 3. Estrogen concentration was significantly decreased in women with delayed menstrual cycles after administration of Jokyungjongoktang during the critical interval of ovulation. 4. Peogesterone concentration significantly increase in women with delayed menstrual cycles after administration of Jokyungjongoktang, respectively, during the postovulatory phase. According to the above results, it can be considered that Jokyungjongoktang restore menstruation and pregnancy-related hormones to normal serum levels of women with normal menstrual cycles by activating maturation of ovum and action of estrogen during the preovulatory phase, ovulation and progesterone synthesis during the critical interval of ovulation, and nidation and endometrium sufficient for the continued pregnacy during the postovulatory phase in women with delayed menstrual cycles.

To investigate the factors that affect the fertilization and cleavage rates of mature oocytes, 44 patients undergoing controlled ovarian hyperstimulation(COH) with FSH/hMG/hCG regimen for IVF - ET were analyzed. During follicular phase, serum LH levels were measured by radioimmunoassay and bioassay. Based on the mean follicular immunoactive LH(i-LH) and bioactive LH(b-LH) levels, patients were divided into 3 groups, respectively. There were no significant differences in basal serum FSH levels on menstrual cycle day 3, serum estradiol($E_2$) and progesterone ($P_4$) levels on the day of hCG administration, and the numbers of follicles aspirated and oocytes retrieved among groups. In relation to the mean follicular i-LH levels, the fertilization and cleavage rates of mature oocytes did not show a significant difference among groups. However, in groups with higher mean follicular b-LH levels, the fertilization and cleavage rates were reduced significantly. During late follicular phase, day-to-day variance in b-LH levels was not significant, but there was a significant difference among groups. There was no significant correlation between serum P. and b-LH levels. These data suggest that the fertilization and cleavage rates of mature oocytes are adversely affected by the raised mean follicular b-LH levels, and monitoring of serum b-LH levels is more useful in COH when compared with i-LH. It appears that the reduced rates are not due to the attenuated endogenous LH surge.

Photoperiodism is an important adaptive phenomenon in various physiological parameters including reproduction to cope with seasonal changes. Involvement of extraretinal photoreceptors in the photoperiodism in non-mammalian vertebrates has been well established. In addition, circadian clock system is known to be involved in the photoperiodic time measurement. The pathway consists of light-input system, time measurement system (circadian clock), gonadotropin releasing hormone (GnRH) production in the hypothalamus, luteinizing hormone (LH) and follicle stimulating hormone (FSH) production in the pituitary, and final gonadal development. Recently, several laboratories reported photopigments newly cloned in the pineal, eyes and deep brain in addition to already known visual pigments in the retina. These are pinopsin, parapinopsin, VA-opsin, melanopsin, etc. All these photopigments belong to the opsin family having retinal as the chromophore. However, the function of these photopigments remains unknown. I reviewed the studies on the location of the photopigments by immunocytochemistry. I also discussed the results on the action spectra for induction of gonadal development in relation with the location of the photoreceptors. Various physiologically active substances distribute in the vertebrate brain. Such substances are GnRH, GnIH, neuropeptide Y, vasoactive intestinal peptide, c-Fos, galanin, neurosteroids, etc. I summarized the immunhistochemical studies on the distribution and the photoperiodic changes of these substances and discussed the route from the deep brain photoreceptor to GnRH cells.

생쥐의 난자는 특별한 첨가물이나 난구세포 없이 체외 배양해도 성숙율이 높은 반면 돼지 난자의 체외성숙율은 매우 낮다. 본 연구는 이러한 차이의 원인을 연구하기 위하여 생쥐와 돼지 난자의 에너지 생성에 관여하는 유전자인 malate dehydrogenase(Mor2)의 기능을 RNAi를 이용하여 비교 분석하였다. 생쥐와 돼지 각각의 Mor2 double-stranded RNA(dsRNA)를 제작하고, 생쥐는 난구세포를 제거한 미성숙(GV) 난자의 세포질에 mMor2 dsRNA를 미세 주입한 후 16시간 동안 배양하였고, 돼지는 난구세포를 제거하거나(DO) 혹은 그대로인 상태(COCs)로 pMor2 dsRNA를 미세 주입한 후 48시간 동안 배양하였다. 사용한 배양액은 M199에 10%의 porcine follicular fluid, pyruvate, p-FSH, EGF, cystein, estradiol-$17{\beta}$ 등이 첨가된 배양액을 사용하였고, 배양 후 난자의 형태학적 변화를 관찰하고, Mor2 mRNA양의 변화를 RT-PCR로 확인하여 RNAi 결과, 염기서열 특이적으로 Mor2 발현이 억제됨을 확인하였다. 돼지 난자의 pMor2 RNAi 결과, DO 난자에서는 약 58%의 난자가 MI에서 성숙이 억제되었으나, COCs에선 84.4%가 MII로 성숙하는 것을 볼 수 있었다. 이는 돼지의 난구세포가 난자 성숙에 매우 중요하며, 특히 malate 공급에 관여할 것임을 시사한다. 선행 연구 Mor2 RNAi 결과, 생쥐는 GV에서, 본 연구에서 돼지는 MI에서 성숙이 정지되었기 때문에 이러한 차이가 배양액의 차이인지 다시 mMor2 RNAi 후 생쥐 난자를 M199 배양액에 16시간 동안 배양한 후 성숙율을 관찰하였더니 MII로의 성숙율은 62%로 대조군과 비교하여 큰 차이가 없었다(non-injected: 76.8%, buffer-injected: 73.3%). 이는 mMor2 RNAi 결과가 배양액의 조성에 의해 극복될 수 있음을 보여준 결과다. 생쥐와 돼지에서 서로 다른 대사과정을 갖고 있음은 바로 이 두 종에서의 체외성숙율 차이의 원인이 될 수 있을 것이며, 앞으로 두 종에서의 난자와 난구세포간의 상호작용 및 대사 경로 등에 관한 심도 깊은 비교 분석 연구를 통하여 돼지의 체외성숙율을 증가시킬 수 있는 배양 시스템의 개발이 가능할 것으로 기대된다.

Objective: To evaluate correlations between serum anti-M${\ddot{u}}$llerian hormone (AMH) levels, phenotypes of polycystic ovary syndrome (PCOS), obesity, and metabolic parameters in patients with PCOS. Methods: A total of 175 patients with PCOS were diagnosed according to the Rotterdam Consensus were included. Exclusion criteria were age over 40, FSH>25 mIU/mL, and 17a-OHP>1.5 ng/mL. The Phenotypes of PCOS were divided into a severe form (oligo-anovulation, ANOV/hyperandrogenism/polycystic ovary morphology [PCOM]; n=59) and a mild form without HA (ANOV/PCOM, n=105). The serum AMH levels were classified into 3 groups (<5 vs. 5-10 vs. >10 ng/mL). Obesity was defined as body mass index (BMI) ${\geq}25kg/m^2$ (n=34). Results: The mean age was $25.9{\pm}5.7$ year and mean AMH level was $10.1{\pm}5.4$ ng/mL. The BMI ($kg/m^2$) was higher in group 1 ($24.2{\pm}6.3$) than in group 2 ($21.9{\pm}4.3$, p=0.046) or group 3 ($21.6{\pm}3.3$, p=0.019). There was no difference among the three groups in age, menstrual interval, antral follicle counts, androgens, or other metabolic parameters. The obesity group showed significantly lower AMH ($7.7{\pm}3.9$ ng/mL vs. $10.7{\pm}5.6$ ng/mL), p=0.004) and low-density lipoprotein levels ($93.1{\pm}21.2$ mg/dL vs. $107.5{\pm}39.3$ mg/dL, p=0.031), and showed higher total T ($0.74{\pm}0.59$ L vs. $0.47{\pm}0.36$ ng/mL, p=0.001), free T ($2.01{\pm}1.9$ vs. $1.04{\pm}0.8$ pg/mL, p=0.0001), and free androgen index ($6.2{\pm}7.9$ vs. $3.5{\pm}3.0$, p=0.003). After controlling for age factors and BMI, the serum AMH levles did not show any significant correlations with other hormonal or metabolic parmeters. Conclusion: For PCOS patients under the age 40, serum AMH is not negatively correlated with age. High serum AMH levels can not predict the phenotype of PCOS and metabolic disturbances in PCOS patients in the non-obese group. Further study might be needed to define the relation more clearly.
