  • The purpose of this study is to identify the presence of the circulating antibodies directed toward ovarian proteins{antiovarian antibodies, AOA) and the nature of antigenic ovarian structure by comparing the binding activities to 4 types of ovarian proteins, particulated and solubilized forms of pig ovarian and granulosa cell membranes in sera of patients with premature ovarian failure(POF) and to evaluate the usefulness of circulating AOA as a follow up tool after treatment. Measurements of AOA were performed by enzyme linked immunosorbent assay(ELISA) in sera of 58 patients with POF, 51 had normal chromosomes and 7 had X chromosome abnormalities. Sera of 21 natural menopausal women and 17 castrated women were also tested and sera of 32 healthy premenopausal women were served as controls. ELISA reactivities against particulated porcine granulosa cell membrane proteins was the greatest among 4 different ovarian proteins. Fifteen(29%) of 51 POF patients with normal chromosome and 1(14.3%) of 7 POF patients with X chromosome abnormalities had AOA while none of 32 controls and 21 natural menopausal women and 17 castrated women had AOA. One POF patient with 47, XXX was identified AOA positive. The ELISA reactivities were followed up monthly up to 5 months in 4 AOA positive POF patients after estrogen-progestin{E-P) therapy. There was a decreasing tendency of the ELISA reactivities in all these patients after E-P therapy and two of them converted to AOA negative. These data suggest that antigenic structure may be components of granulosa cell membrane and the determination of circulating AOA may be useful in the follow up after treatment in patients with autoimmune POF.

  • Premature ovarian failure (POF) is a long-term adverse effect of chemotherapy treatment. However, current available treatment regimens are not optimal. Emerging evidence suggests that bone marrow-derived mesenchymal stem cells (BMSCs) could restore the structure and function of injured tissues, but the homing and restorative effects of BMSCs on chemotherapy injured ovaries are still not clear. In this study, we found that granulosa cell (GC) apoptosis induced by cisplatin was reduced when BMSCs were migrated to granulosa cells (GCs) in vitro. Chemotherapy-induced POF was induced by intraperitoneal injection of cisplatin in rats. BMSCs labeled with enhanced green fluorescent protein (EGFP) were injected into the rats via the tail vein to investigate the homing and distribution of BMSCs in vivo. The number of BMSCs in the ovarian hilum and medulla was greater than in the cortex, but no BMSCs were found in the follicles and corpus lutea. In addition, the BMSCs treatment group's antral follicle count and estradiol levels increased after 30 days, compared with the POF group. Hence, our study demonstrates that intravenously delivered BMSCs can home to the ovaries, and restore its structure and function in POF model rats.

  • Objectives: The purpose of this study is to report the effects of Korean medical treatment in ovarian disorder patients resistant to controlled ovarian hyperstimulation. There are some case-reports about effectiveness of the Korean medical treatment to treat ovulation disorder and become pregnant, but cases are still deficient. Methods: The patient was diagnosed possibility of premature ovarian failure by serum hormone assay and underwent hyperstimulation to freeze oocyte. But ovary had no response to hyperstimulation. She was treated by Korean medical treatment, such as herbal medicine, acupuncture and moxibustion. Results: After the treatment, the patient recovered from irregular ovulation & menstrual cycle and became pregnant and gave birth. Conclusions: This case shows the Korean medical treatment might be effective in ovarian disorder patients resistant to hyperstimulation.

  • BPES($\underline{B}$lepharophimosis/$\underline{P}$tosis/$\underline{E}$picanthus inversus $\underline{S}$yndrome)는 FOXL2 유전자의 돌연변이에 의해 유발되는 상염색체 우성질환이다. 눈꺼풀이 갈라지거나 쳐지고 넓은 미간이 나타나는 특징이 있으며, 여성의 조기 난소 부전증(premature ovarian failure, POF)을 일으켜 불임을 유발한다. FOXL2는 forkhead family에 속하는 전사인자로서 FOXL2가 결여된 난소에서는 granulosa cell의 분화가 진행되지 않아 난포 성숙과정의 멈춤과 난자의 폐쇄증을 유발한다. FOXL2를 bait로 하여 rat의 난소 cDNA 라이브러리의 yeast two-hybrid screening을 시행하여 FOXL2 단백질과 상호작용을 하는 small ubiquitin-related modifier(SUMO)-conjugating E2 효소인 UBE2I 단백질을 찾았다. UBC9이라고도 알려진 UBE2I 단백질은 SUMO 변형 과정을 위한 필수적인 단백질이다. Sumoylation은 수 많은 전사인자의 전사능력의 조절을 포함하여 다양한 신호전달체계에 관여하는 번역 후 변형 과정이다. 본 연구에서 인간세포인 293T 내에서 면역침전반응 실험을 통해 FOXL2와 UBE2I의 단백질-단백질간의 상호작용을 확인하고, FOXL2의 돌연변이형을 제작하여 yeast two-hybrid system을 이용해 UBE2I와 결합에 필요한 FOXL2의 부분을 규명하였다. 따라서, FOX2에 상호작용하는 UBE2I의 규명은 sumoylation에 의한 FOXL2의 새로운 조절 메커니즘을 시사한다.

  • This study was performed to determine whether the $LH{\beta}$-subunit gene missense mutation is present in Korean infertile patients with 46,XX POF women. The variants of $LH{\beta}$ exon 2 (Trp 8Arg; TGG to CGG and Ile15Thr; ATC to ACC) were studied in forty-four 46,XX idiopathic POF and 54 nonpregnant women. The $LH{\beta}$ exon 2 variants were more frequent in POF patients (20.5%) than nonpregnant (16.7%) women (p>0.05). POF patients with the variant was slightly higher than nonpregnant women with the variant.

  • Purpose : To research the Skin Resistance Variability(SRV) of premature ovarian failure(POF) patients by Autonomic Bioelectric Response Recorder(ABR-2000 system, Meridian, Korea) and report the specific results in SRV of POF patients. Methods : We measured SRV of 17 POF Patients who came to Conmaul Oriental Medical Hospital during August 2005 ${\sim}$ July 2006 by ABR-2000 system. We analyzed the results which height of graph Part was converted into 0${\sim}$10, and the readings of Low/Normal/High. Results : The mean value of graph height on each(1, 2, 3) part is lower than normal range(4-6) in POF patients. The distribution ratio of Low/Normal/High on each(1, 2, 3) part shows that there are much more Low proportion in POF patients. Conclusion : The low graph height of POF patients on 1, 2, 3 part means that conductivity & capacitance of POF patients is low, especially on head.
