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.

Follicular fluid(FF) prostaglandin $E_2$(PG$E_2$) and $PGF_{2{\alpha}}$ levels were compared in 3 groups of spontaneously ovulatory women undergoing ovulation induction with clomiphene citrate (CC) alone or with human menopausal gonadotropin(hMG) (14 patients), hMG(9 patients), or pure FSH/hMG(11 patients) for the purpose of in vitro fertilization. FF volume aspirated did not differ significantly according to the maturity of the oocyte. According to hyperstimulation regimens, the volume of FF from which preovulatory occytes were obtained was significantly less in the hMG-treated group than in the other groups. In follicles of preovulatory oocytes, FF PG$E_2$ values were significantly lower in the FSH treated group than in the Cc.treated or hMG-treated group, and FF $PGF_{2{\alpha}}$ values were significantly higher in the hMG-treated group than in the CC-treated or FSH-treated group. In follicles of immature or atretic oocytes, there was no significant difference in FF PG$E_2$ and PG$F_{2{\alpha}}$ concentrations of the similar morphology of the oocyte according to hyperstimulation regimens. In all cycles, FF PG$E_2$ and PG$F_{2{\alpha}}$ values of preovulatory oocytes were not significantly different from those of immature oocytes, but those of atretic oocytes were relatively lower than those of fertilizable oocytes and it was statistically signifincant in PG$E_2$ values of CC-treated group. In all treatment groups, FF PG$E_2$ and PG$F_{2{\alpha}}$ levels did not show and close relationship with the success of fertilization in vitro and of pregnancy after embryo transfer. Above results suggested that FF PG$E_2$ and PG$F_{2{\alpha}}$ be involved in oocyte maturation and ovulation, but their relationship with the success of in vitro fertilization was not found.

인간난자의 체외수정 및 배아의 자궁내이식 후 황체기 혈청 난포호르몬 및 황체호르몬의 변동에 관한 연구

Steroid hormone profiles during luteal phases after in vitro fertilization(IVF) and embryo transfer(ET) have been evaluated in 83 cycles stimulated by pure follicle-stimulating hormone/human menopausal gonadotropin/human chorionic gonadotropin, in which 13 patients became pregnant. Serum estradiol($E_2$) and progesterone($P_4$) levels were determined on days 2, 5, 7 and 9 after laparoscopic follicle aspiration. The follicular $E_2$ peak was slightly higher in pregnancies than in failures. Positive correlations were observed between the follicular $E_2$ peaks and the $P_4$ levels on days 5 and 7 of the luteal phase in pregnancies, but no correlation was found in failures. The $E_2$ and $P_4$ levels on days 5 and 7 of the luteal phase were significantly higher in pregnancies than in failures, but not different on days 2 and 9. Values of the $P_4/E_2$ ratio were similar between the two groups. The luteal phase durations were 12 to 19 days and no correlation was observed between the lengths of luteal phase and the luteal $E_2$ or $P_4$ concentrations. These data suggest that high $P_4$ levels in the mid-luteal phase, which have positive correlations with the follicular $E_2$ peaks, might have a favorable influence on the pregnancy success in human IVF.

이진용,황현태,이명재,김용철,염병우,Lee, Jin-Yong,Hwang, Hyoun-Tae,Yi, Myeong-Jae,Kim, Yong-Cheol,Yum, Byoung-Woo 한국지하수토양환경학회 2007 지하수토양환경 Vol.12 No.4

최근에 형광물질을 이용한 추적자 시험이 빈번해지고 있다. 본 연구에서는 형광물질 추적자 시험시 농도측정 방법으로서 입상 활성탄을 이용하는 방법의 적용가능성을 실내 및 현장실험을 통해 평가하였다. 실내실험 결과 로다민 WT 및 우라닌 개별용액의 경우 활성탄 흡착 농도는 실제 표준농도와는 일부 차이가 있지만 각 표준농도와 선형성은 매우 뛰어난 것으로 나타났다. 또한 $10{\mu}g/L$ 이상의 형광물질 농도에서는 활성탄의 적용성이 뛰어났다. 한편 두 형광물질을 혼합한 경우에는 간섭의 영향으로 활성탄 적용성이 떨어졌다. 실제 현장에서 활성탄을 이용하여 추적자 시험을 한 결과, 통상적으로 수행하는 직접적인 물시료 채취분석법과 비교하였을 때 활성탄을 이용한 흡착방법도 충분히 현장 적용성이 있으며 저농도에서는 습식 그리고 고농도에서는 건식으로 분석한다면 보다 정확한 형광물질 농도측정이 되는 것으로 나타났다. 특히 오염물질 확산 평가 등이 목적이 아니라 추적자 물질의 도달확인(즉 수리적 연결성 진단)이 주요 목적이고 추적자시험의 예상 소요기간이 길다면 활성탄을 활용한 방법은 매우 비용경제적일 것으로 사료된다. In recent tests using tracer have been frequently conducted by fluorescent tracers. In this study, granular activated charcoal (GAC) as a detector for the fluorescent tracers (rhodamine WT and uranine) was investigated through laboratory and field tests. In the laboratory tests, tracer concentrations of rhodamine WT and uranine determined by the GAC were slightly different from those of standard solutions but they were excellent in linearity. Results show that GAC is excellent as tracer detector when concentration of the fluorescent tracers is greater than 10 & micro; g/L whileas no obvious differences in mixed solutions of the two tracers due to interferences. Compared to conventional methods of water sampling, field results shows a high potential of GAC as a tracer in the field. Our results also show that wet analysis is better for the lower concentrations of tracers whileas dry analysis is good for high concentrations of tracers. This study demonstrates that fluorescent tracer detection using the GAC is very useful and economical for a hydraulic connection between target areas and very longer period of the tracer test.

Follicular flxid (FF) and their matched oocytes were obtained from 58 follicles of 27 women who underwent an in vitro fertilization (IVF) procedure with ovarian hyperstimulation by clomiphene citrate(n=8), hMG(n=9),FSH/hMG(n=10). Follicular aspiration was performed 36 hours after human chorionic gonadotropin administration. The concentcation of androstendione (ADD), testosterone (T) was correlated with hyperstimulation regimens, the morphology of the oocyte-corona-cumulus complex (OCCC), oocyte fertilization, and the incidence of pregnancy after embryo transfer. The results were as follows. 1. According to hyperstimulation regimens, there was no significant differance in FF ADD and T concentrations of the similar morphology of OCCC. 2. In clomiphene-treated and FSH/hMG-treated cycles, FF ADD concentrations of preovulatory oocytes were 43.09${\pm}$9.53 ng/ml and 59.46${\pm}$9.09 ng/ml, those of immature occytes were 96.98${\pm}$16.55 ng/ml and 116.13${\pm}$36.81 ng/ml, those of atretic oocytes were 246.5 ${\pm}$9.25 ng/ml and 634.25${\pm}$9.25 ng/ml respectively, reflecting the significant relationship between FF ADD level and morphologic maturity of OCCC (p<0.05). But in hMG-treated cycles, such relationship was not found (p>0.1). In clomiphene-treated and FSH/hMG-treated cycles, FF T concentrations of preovulatory oocytes were 11.37${\pm}$2.38 ng/ml and 11.68${\pm}$1.73 ng/ml respectively which were significantly lower than those of atretic oocytes (25.1${\pm}$7.50 ng/ml and 23.25${\pm}$0.95 ng/ml respectively) (p<0.05). But in all cycles, FF T concentrations of immature oocytes were not significantly different from those of preovulatory oocytes, artetic oocytes (p>0.1). 3. In hMG-treated and FSH/hMG-treated cycles, FF ADD concentrations of fertilized oocytes were 32.43${\pm}$4.09 ng/ml and 42.61${\pm}$4.82 ng/ml respectively which were significantly lower than those of non-fertilized oocytes (72.18${\pm}$17.31 ng/ml and 108.09${\pm}$17.32 ng/ml respectively) (p<0.05), but in clomiphene-treated cycles there was no significant difference (p>0.1). In FSH/hMG-treated cycles, FF T concentration of fertilized oocytes was 7.33${\pm}$1.06 ng/ml which was significantly lower than that of non-fertilized oocytes (20.3${\pm}$6.21 ng/ml) (p>0.02), but in clomiphne-treated and hMG-treated cycles there was no significant difference (p>0.1). 4. In all cycles FF ADD and T concentrations did not correlated with the success of pregnancy after embryo transfer. Above results suggested that FF ADD and T may play an important role in oocyte maturation and fertilization, but their relationship with the success of psegnancy was not found.

Objetives The late research tendency on atopic dermatitis is mainly focused on the experiment of unbalance of cytokine released from T cell subtype. Merhods As there's no experiment with herbal medicine using Hanghaedan(HHD), we isolated and cultured monocytes of atopic dermatitis pateints (AD) peripheral blood, for knowing the influence of HHD on the secretory function of IL-4, IL-5, $IFN-{\gamma}$. Results 1. In AD group, HHD exhibits statistically significant inhibitory effect on IL-4(p<0.05). 2. In AD group, HHD exhibits statistically significant inhibitory effect on IL-5(p<0.05). 3. In AD group, HHD exhibits statistically significant inhibitory effect on $IFN-{\gamma}$ (p<0.01). 4. Sample group comparing with the cytokine concentration rate value of AD patients and that of NAD patients IL-4 of AD patients exhibits statistically significant decrease(p<0.05). 5. In AD group, there is no significant relation between serum IgE and cytokines. 6. In AD group, there is no significant relation between total eosinophil and IL-5. Conclusions Effects of Hanghaedan on the cytokine(IL-4, IL-5, $IFN-{\gamma}$) secretory function of monocytes of atopic dermatitis patients is recognized.
