For the flexible and rational distribution of limited existing health resources based on measurements of individual risk, the socalled Risk Approach is being proposed by the World Health Organization as a managerial tool in maternal and child health care program. This approach, in principle, puts us under the necessity of developing a technique by which we will be able to measure the degree of risk or to discriminate the future outcomes of pregnancy on the basis of prior information obtainable at prenatal care delivery settings. Numerous recent studies have focussed on the identification of relevant risk factors as the Prior infer mation and on defining the adverse outcomes of pregnancy to be dicriminated, and also have tried on how to develope scoring system of risk factors for the quantitative assessment of the factors as the determinant of pregnancy outcomes. Once the scoring system is established the technique of classifying the patients into with normal and with adverse outcomes will be easily de veloped. The scoring system should be developed to meet the following four basic requirements. 1) Easy to construct 2) Easy to use 3) To be theoretically sound 4) To be valid In searching for a feasible methodology which will meet these requirements, the author has attempted to apply the“Likelihood Method”, one of the well known principles in statistical analysis, to develop such scoring system according to the process as follows. Step 1. Classify the patients into four groups: Group $A_1$: With adverse outcomes on fetal (neonatal) side only. Group $A_2$: With adverse outcomes on maternal side only. Group $A_3$: With adverse outcome on both maternal and fetal (neonatal) sides. Group B: With normal outcomes. Step 2. Construct the marginal tabulation on the distribution of risk factors for each group. Step 3. For the calculation of risk score, take logarithmic transformation of relative proport-ions of the distribution and round them off to integers. Step 4. Test the validity of the score chart. h total of 2, 282 maternity records registered during the period of January 1, 1982-December 31, 1982 at Ewha Womans University Hospital were used for this study and the“Questionnaire for Maternity Record for Prenatal and Intrapartum High Risk Screening”developed by the Korean Institute for Population and Health was used to rearrange the information on the records into an easy analytic form. The findings of the study are summarized as follows. 1) The risk score chart constructed on the basis of“Likelihood Method”ispresented in Table 4 in the main text. 2) From the analysis of the risk score chart it was observed that a total of 24 risk factors could be identified as having significant predicting power for the discrimination of pregnancy outcomes into four groups as defined above. They are: (1) age (2) marital status (3) age at first pregnancy (4) medical insurance (5) number of pregnancies (6) history of Cesarean sections (7). number of living child (8) history of premature infants (9) history of over weighted new born (10) history of congenital anomalies (11) history of multiple pregnancies (12) history of abnormal presentation (13) history of obstetric abnormalities (14) past illness (15) hemoglobin level (16) blood pressure (17) heart status (18) general appearance (19) edema status (20) result of abdominal examination (21) cervix status (22) pelvis status (23) chief complaints (24) Reasons for examination 3) The validity of the score chart turned out to be as follows: a) Sensitivity: Group $A_1$: 0.75 Group $A_2$: 0.78 Group $A_3$: 0.92 All combined : 0.85 b) Specificity : 0.68 4) The diagnosabilities of the“score chart”for a set of hypothetical prevalence of adverse outcomes were calculated as follows (the sensitivity“for all combined”was used). Hypothetidal Prevalence : 5％ 10％ 20％ 30％ 40％ 50％ 60％ Diagnosability : 12% 23% 40% 53% 64% 75% 80%.

General PCR technique alone has a limitation for preimplantation genetic diagnosis(PGD) using single blastomere. Recntly developed primer extension preamplification(PEP) technology amplifies the whole genome and thus, simultaneous multiple locus analysis became possible. In this study, we report the efficacy of PEP-PCR for PGD in three muscular dystrophy carriers undergoing IVF-ET. A total of 37 blastomeres were obtained from 40 embryos at six to eight cell stage in three IVF cycles in two DMD and one BMD carriers. Whole genome from single blastomeres were amplified using I5-base oligonucleotide random primers. PCR amplified products of exon 45 in the dystrophin gene and alphoid X/Y loci for gender determination were analysed by 2% metaphor gel electrophoresis. A total of 37 PEP-PCR replicates from 37 single blastomeres from 40 embryos and 37 blanks were performed. We obtained the reliable results for exon 45 and alphoid X/Y. Transfer of female embryos and unaffected male embryo was attempted in three couples. Unfortunately, pregnancy was not achieved in these cases. PEP-PCR is a reliable and efficient PGD method in multiple locus analysis using single blastomere.

Purpose: This prospective cohort study was done to investigate recall bias to antepartum variables measured at postpartum periods and predictors of postpartum depression. Methods: Participants were 215 women who answered a self-administered questionnaire which included demographics, Postpartum Depression Predictors Inventory-Revised and Korean version of Edinburgh Postpartum Depression Scale at antepartum 36-40 weeks and postpartum 2 weeks and 6 weeks. Data were analyzed using kappa, and hierarchical multiple logistic regression. Results: Agreement between antepartum variables at both antepartum and two postpartum periods was relatively high (${\kappa}$=.55- .95). Postpartum depression rates were 36.3% and 36.7% at two follow-up points. In hierarchical multiple logistic regression analysis, prenatal depression (OR=4.32, 95% CI: 1.41-13.19; OR=5.19, 95% CI: 1.41-19.08), social support (OR=1.40, 95% CI: 1.18-1.66; OR=1.27, 95% CI: 1.06-1.53) and maternity blues (OR=4.75, 95% CI: 1.89-11.98; OR=4.22, 95% CI: 1.60-11.12) were commonly associated with postpartum depression at two follow-up points. Child care stress (OR=1.85, 95% CI: 1.01-3.37) was only associated with postpartum depression at 2 weeks postpartum and pregnancy intendedness (OR=1.57, 95% CI: 1.09-2.27) was only associated with postpartum depression at 6 weeks postpartum. Conclusions: The results indicate a need to apply nursing interventions such as prenatal education and counseling with families from antenatal period.

Previous studies have shown that glucocorticoid suppresses microsomal epoxide hydrolase(EH) gene expression and that EH expression is altered during pregnancy. The effects of progesterone on the expression of rat EH and certain glutathione S-transferase(GST) genes were examined in this study. Northern RNA blot analysis revealed that progesterone was effective in increasing hepatic EH mRNA levels at 12 h to 48 h after treatment with a maximal 9-fold increase being noted at 12 h time point. Nonetheless, multiple daily treatment with progesterone rather caused minimal relative increases in EH mRNA levels. GST Ya and Yb1/2 mRNA levels were also transiently elevated at 12 h after progesterone treatment, followed by gradual decreases from the maximal Increases at day 1, 2 and 5 post-treatment. These changes in EH and GST mRNA levels were noted only at a relatively high dose of progesterone. Furthermore, immunoblot analyses showed that rats treated with progesterone for 5 days failed to show EH or GST induction, indicating that progesterone-induced alterations in EH and GST mRNA levels do not reflect bona fide induction of the detoxifying enzymes. Concomitant progesterone treatment of rats with the known EH inducers including ketoconazole and clotrimazole failed to additively nor antagonistically alter EH mRNA levels. In contrast, dexamethasone substantially reduced ketoconazole- or clotrimazole-inducible EH expression. These results showed that progesterone stimulates the EH, GST Ya and Yb1/2 gene expression at early times followed by marked reduction in the RNA levels from the maximum after multiple treatment and that the changes in mRNA do not necessarily reflect induction of the proteins.

This study was done to provide basic data on prevention of breast cancer by identifying and analyzing risk factors for breast cancer in Korean women. The data were collected from three hospitals. The data from Jan. 1995 to Dec. 1997 was based on the patient recordings and personal contacts if possible. Data from 1998 to 1999 was collected from 280 inpatients and outpatients diagnosed as breast cancer. From this data, information about the risk factors of breast cancer could be acquired. The factors are scaled according to the degree of risk. Menstrual history, obstetrical history, family history. lactation period, life style were given 5 point, and body mass index was given 4 point. Using one-way ANOVA. the most important risk factors were identified and analyzed by multiple regression. The conclusion of this study are as follows : General factors which would show an effect on the results of the multiple regression included risk factors such as menstrual history, obstetrical history, lactation period, family history, and life style factors including mortal state, monthly income, educational level, job and age. Family history(R=0.481) was found to be the highest risk factor(23.1%) affecting breast cancer risk. The next factors were dying hair(R=0.603), drinking(R=0.846), body mass index(R=0.885), smoking(R=0.916), age of menopause(R=0.937), pregnancy age of first full-term(R=0.957), eating vegetable(R=0.980) and the number of full term pregnancies in that order. The sum total(R=0.986) of all the above factors accounted for 97.3% of the risk of breast cancer for Korean women. In conclusion, it was found that family history and dyeing hair were the highest risk factors for breast cancer. It is recommended that those with a family history of breast cancer should have regular breast examinations, and those who often dye their hair should reconsider this practice.

Objective: Autophagy is highly active in ovariectomized mice experiencing hormone deprivation, especially in the uterine mesenchyme. Autophagy is responsible for the turnover of vasoactive factors in the uterus, which was demonstrated in anti-Müllerian hormone receptor type 2 receptor (Amhr2)-Cre-driven autophagy-related gene 7 (Atg7) knockout (Amhr-Cre/Atg7^f/f mice). In that study, we uncovered a striking difference in the amount of sequestosome 1 (SQSTM1) accumulation between virgin mice and breeder mice with the same genotype. Herein, we aimed to determine whether repeated breeding changed the composition of mesenchymal cell populations in the uterine stroma. Methods: All female mice used in this study were of the same genotype. Atg7 was deleted by Amhr2 promoter-driven Cre recombinase in the uterine stroma and myometrium, except for a triangular stromal region on the mesometrial side. Amhr-Cre/Atg7^f/f female mice were divided into two groups: virgin mice with no mating history and aged between 11 and 12 months, and breeder mice with at least 6-month breeding cycles with multiple pregnancies and aged around 12 months. The uteri were used for Western blotting and immunofluorescence staining. Results: SQSTM1 accumulation, representing Atg7 deletion and halted autophagy, was much higher in virgin mice than in breeders. Breeders showed reduced accumulation of several vasoconstrictive factors, which are potential autophagy targets, in the uterus, suggesting that the uterine stroma was repopulated with autophagy-intact cells during repeated pregnancies. Conclusion: Multiple pregnancies seem to have improved the uterine environment by replacing autophagy-deficient cells with autophagy-intact cells, providing evidence of cell mixing.

The sucess of intrauterine inseminations with washed human spermatozoa was evaluated in 92 patients. In according to indication of insemination, intrauterine inseminations of women with hostile cervical mucus yield a 35.3% and 12.8% with male factors and 27.3% with unexplained infertility. In ovulation induction group with variable agents including clomiphen, human menopausal gonadotropin (HMG) and GnRH analog, the pregnancy rate was 27.8% (22/79) and in natural cycle group, 15.4% (2/13). The fetal loss rate in insemination group was 12.5% (3/24). Multiple pregnancies were 7 cases and ovulation induction were performed in 6 cases among them. Intrauterine insemination with washed human spermatozoa therefore represents an effective and safe procedure selected infertile couples.

Purpose: The purpose of this study was to determine the stress, depression, and fetal attachment of pregnant women who underwent infertility treatment, and to identify factors associated with fetal attachment. Methods: As a correlation survey design, data were collected from 136 pregnant women who underwent infertility treatment. Data were analyzed using ${\chi}^2$-test, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: Stress, depression, and fetal attachment averaged $3.01{\pm}0.60$ (range of scale 1~5), $10.02{\pm}6.51$ (out of a possible 63), and $3.64{\pm}0.55$ (range of scale 1~5), respectively. Level of fetal attachment was higher when mother's age was less than 35, having other children, and having prenatal education experience. Lower score of depression and client's age less than 35 were significant factors affecting fetal attachment. Conclusion: Infertility is a life-affecting trauma for the individual, and personal and social changes due to infertility cause physical and psychological difficulties even after a successful pregnancy with infertility treatment. Therefore, prenatal management programs need to be developed giving consideration to the emotional and physical changes in order to promote physical and psychological stability in the women pregnant following infertility treatment.
