Objectives: Spontaneous pregnancy is a rare event after repeated failure of in vitro fertilization (IVF) or Intrauterine insemination (IUI) treatment. So this paper is to report the natural pregnancy of Gamiseogagjihwang-tang treatments on two infertile patients who were repeatedly failed in IVF or IUI. Methods: One patient was a 35-year-old patient diagnosed with the adenomyosis and contralateral tubal obstruction, treated with 90 cc Gamiseogagjihwang-tang two times per day for 6 weeks after second failure of IVF. The other patient was a 34-year-old patient undergone induced abortion by three times, treated with 90 cc Gamiseogagjihwang-tang two times per day for 4 weeks after second failure of IUI. Results: Through taking Gamiseogagjihwang-tang without assisted reproduction techniques, two cases got pregnant naturally. Conclusions: These cases suggest that Gamiseogagjihwang-tang is effective in treating infertile female after failure in IVF or IUI and inducing spontaneous pregnancy. Therefore, there needs to be more trial on infertile patients treated with Seogagjihwang-tang.

The effects of Taheebo on the diabetic-piegnant rats and their fetus was investigated. It has been reported that diabetic condition of the pregnant rats can affect the process of liver formation and damage the respiratory function in the fetus. Therefore we investigated the effects of Taheebo on the prevention of liver damage and respiratory failure in the fetus and those results were compared with that of dexamethasone (DXM). In pregnant rats, streptozotocin(STZ, 45 mg/kg, 0.01 M citrate buffer) was injected into the pregnant rats on the third day of pregnancy. Methanol extracts of Taheebo(500 mg/kg p.o.) was administered once daily during pregnancy. DXM (10 $\mu\textrm{g}$/g i.p.) was injected into the pregnant rats in 16th and 18th days of pregnancy. Body weights were measured and fetal number and abortion rate in pregnancy rats were determined. Lecithin/sphingomyelin ratio in amniotic fluid and malondialdehyde, glycogen, triglyceride, protein and cholesterol levels in the liver homogenate were determined. Also blood glucose level was analyzed. Body weights of maternal rats were increased in the all groups except the DXM group. Fetal number of the Taheebo treated group was similar to the control group, and a significant increase in the body weights of fetus was observed in the STZ treated group and the Taheebo treated group compared with the control group. Blood glucose of fetus produced hypoglycemia in the control group and hyperglycemia in the diabetic-pregnant rats. The protein and cholesterol levels in fetus liver were significantly increased in the DXM treated group compared with the control group. Triglyceride content was significantly increased in all groups compared with the control group. Liver malondialdehyde level of fetus in the STZ treated group was similar to the control group. Glycogen level was significantly increased in the all groups compared with the control group. Methanol extract of Taheebo showed hypoglycemic effect on the pregnant rats. However, we could not observe any hypoglycemic effect on the fetus. There's no difference between the control and Taheebo treated group in terms of the levels of triglyceride, cholesterol, protein and glycogen in the fetus liver. Further study to identify the effect of Taheebo on the fetus is under investigation.

농촌 여성들의 출산력과 임신소모율을 조사하기 위해 군위군에 거주하는 15-49세의 여성 가운데 조사시작 당시 영구불임 수술을 하지 않은 유배우 가임여성을 대상으로 17명의 면 보건요원들이 1985년 4원 1일부터 1987년 3월 31일까지 2년간 추적 관찰하여 그들의 피임 실천율, 출산율 그리고 임신 소모율을 조사하였다. 총 관찰된 6,826 여성인년 가운데 피임을 실천한 기간은 3,522인년(51.6%), 임신, 유산 그리고 출산을 한 기간은 519인년(7.6%)이었으며 피임을 하지 않은 기간은 2,491인년(36.5%)이었다. 조사시작 당시에 영구불임 수술을 한 사람을 포함시켰을 경우에는 피임을 실천한 기간이 72.1%로 전국의 피임 실천율보다 오히려 높은 수준이었다. 그러나 30대 여성의 경우 2-3명의 자녀를 갖고서도 피임을 하지 않고 있는 사람이 약 28%나 되고, 피임을 하는 경우에도 월경 주기법이나 콘돔과 같은 실패율이 높은 피임법을 20대 여성보다 더 많이 쓰고 있었다. 관찰기간 동안 전체적으로는 100 여성인년당 14.3건의 임신이 일어났으며, 25-29세 여성 이 100 여성인년당 27.4건의 임신으로 가장 높은 임신율을 보였다. 전체임신 중 22.0%가 사산(0.9%), 자연유산(3.8%), 그리고 인공유산(17.3%)으로 소모되었다. 연령이 증가함에 따라 임신 소모율이 증가하여 30세 미만 부인의 임신 소모율은 15.8%인데 비해 30대 여성이 임신을 한 경우 37.5%가 인공유산을 하여 자연유산과 사산을 합한 임신 소모율이 43.5%나 되었다. 추적기간 동안에 인공유산으로 종결한 부인이 출생으로 종결한 부인에 비해 평균 자녀수와 자연유산 및 인공유산 경험회수가2배 이상으로 많아 유산을 경험한 사람이 유산을 반복하고 있었다. 출생으로 종결한 임부는 평균 4.2회의 산전 관리를 받았고 분만은 85%가 의료기관에서 일어났으며, 가정 분만은 15%로 전국의 농촌지역에 비해 높은 시설 분만율을 나타냈는데, 이것은 군위군이 일차 보건의료시범사업 지역이었기 때문으로 생각된다. 이와 같은 연구 결과로 보아 농촌 여성을 대상으로 한 가족계획 사업은 30대 여성을 대상으로 하여 경구 피임약이나 자궁내장치와 같이 피임 효과가 높은 피임법을 보급하는데 중점을 두어야 임신 소모율을 줄이고 여성건강을 증진시킬 수 있을 것으로 생각된다.

A survey was conducted by the staff of the College of Medicine and School of Public Health, Seoul National University in cooperation with Seoul Special City from 1 December 1967 through 28 February 1968, on such events as delivery, death, abortion and pregnancy. The survey directed to a total population of 47,811 residing in 9,157 households led us to the following findings: 1. Two year averages of crude birth rate, crude death rate and natural increase rate were 30.1, 5.6 and 24.5, respectively. 2. Of all deliveries, home and hospital deliveries constituted 61.1 per cent and 35.5 per cent, respectively. 3. Deliveries other than hospital deliveries were found to be attended more often by mother-in-laws (26.5 per cent) than by doctors or midwives(23.4 per cent). 4. About 51 per cent of all women having experiences in pregnancy during the last two years had an experience of consulting a doctor at least one time throughout whole period of pregnancy. 5. In most cases scissors were used to cut umbilical cords, of which 71.0 per cent were not sterilized and only 20.3 per cent sterilized. 6. In many cases placenta was incinerated(48.2 per cent) and on many other occasions it was thrown away into water(28.3 per cent). 7. Cement bags(37.4 per cent), gauze and absorbent cotton(29.8 per cent) were found to be most frequently used to receive new-born babies. 8. In 1966 8. 8 per cent of the women had at least one abortion induced and in 1967 the percentage was 9.2 per cent. 9. Nearly all(95.8 per cent) of the induced abortions reportedly were done at doctor's clinics. 10. Of all the abortions induced 65.3 per cent were done by specialists in obstetrics, 30.3 per cent by general practitioners and 2.7 per cent by midwives. 11. Those who experienced spontaneous abortions were 1.9 per cent of all women both in 1966 and 1967. 12. About 9.2 per cent of women investigated were found to be currently pregnant. 13. Age specific death rate turned out to be highest among those under 1 year of age. 14. Ten major causes of death in their order of frequency were: 15. Places of death can be classified into homes(75.3 per cent) and hospitals(13.2 per cent). 16. Method of disposing of corpses comprised burials(54.2 per cent) and cremations(44.6 per cent). 17. Infant, neonatal and hebdomadal mortality rates have been computed at 32.2, 18.9 and 13.7, respectively. 18. Infants were found to have died either at homes(81.5 per cent) or at hospitals(18.5 per cent). 19. Birth registrations had been done for about 18.5 per cent of the dead infants.

The recent DNA microarray technology enables us to understand gene expression profiling in cell line and animal models. The technology has potential possibility to comprehend mechanism of multiple genes were related to compounds which have toxicity in biological system. So, microarray system has been used for the prediction of toxicity through gene expression induced by toxicants. It has been shown that compounds with similar toxic mechanisms produce similar changes in gene expression in vivo system. Here we focus on the use of toxicogenomics for the determination of gene expression analysis associated with hepatotoxicity in rat liver and cell line (WB-F344). Methotrexate (MTX) is a chemotherapy agent that has been used for many years in the treatment of cancer because it affects cells that are rapidly dividing. Also it has been known the toxicity of MTX, in a MTX abortion, it stops embryonic cells from dividing and multiplying and is a non-surgical method of ending pregnancy in its early stages. We have shown DNA microarray analyses to assess MTX-specific expression profiles in vivo and in vitro. Male Sprague-Dawely VAF+ albino rats of 5-6 weeks old and WB-F344 cell line have been treated with MTX. Total RNA was isolated from Rat liver and cell line that has treated with MTX. 4.8 K cDNA microarray in house has been used for gene expression profiling of MTX treatment. We have found quite distinct gene expression patterns induced by MTX in a cell line and in vivo system.

This study examined the effects of different day/night temperature regimes or silver ion on growth and flowering of passion fruit 'Tai-nung No.1'. Low temperature treatment ($20/15^{\circ}C$) caused passion fruit cultivar 'Tai-nung No.1' to fail to flower. Flowering induction occurred within a temperature range of $20-30^{\circ}C$, with no significant difference in the days to first flower bud and the total number of flower buds between plants grown at $30/25^{\circ}C$ and $25/20^{\circ}C$. However, plants grown at $30/25^{\circ}C$ exhibited their first flower buds set on the higher nodes and had higher abortion rates of flower buds than those at $25/20^{\circ}C$. Plants grown at $30/25^{\circ}C$ had the most rapid growth and the shortest plastochron. We also evaluated the effect of the ethylene response inhibitors silver nitrate ($AgNO_3$) and silver thiosulfate (STS) on growth and flowering of potted passion fruit 'Tai-nung No.1', when they were exposed to low temperature conditions ($20/15^{\circ}C$) following chemical treatments ($AgNO_3$ or STS, at 0.5 or 1.0 mM). $AgNO_3$ and STS treatments induced flower formation and initial flower bud formation within approximately two weeks at $20/15^{\circ}C$ whereas non-treated control plants exhibited no flower formation. ACC content and activity of ACC oxidase in the leaves of passion fruit 'Tai-nung No.1'exposed to low temperature conditions ($20/15^{\circ}C$) were significantly inhibited by the ethylene inhibitor treatments. These results indicate that ethylene, which is produced under low temperature conditions, plays an important role in inhibiting flower formation in passion fruit.

Purpose. Professional nursing ethics is a living, dynamic set of standards for nurses' professional moral behavior. Furthermore, in daily clinical nursing training, nursing students are constantly confronted with decision-making that is moral in nature. The aim of this study was to identify the perceived ethical attitudes in the clinical training process of senior nursing students using Q-methodology to offer basic strategies for nursing ethics education and thereby improve patients' care. Methods. Q-methodology provides a scientific method for identifying perception structures that exist within certain individuals or groups. Thirty-seven participants in a university rated 38 selected Q-statements on a scale of 1-9. The collected data were analyzed using pc-QUNAL software. Results. Principal component analysis identified 3 types of ethical attitudes in nursing students in Korea. The categories were labeled Sacred-life, Science-realistic and Humane-life. Sacred-life individuals think that a life belongs to an absolute power (God), not a man, and a human life is a high and noble thing. Science-realistic individuals disagreed that allowing an induced abortion or embryo (human) duplication is unethical behavior that provokes a trend, which takes the value of a life lightly; most of them took a utilitarian position with respect to ethical decisions. Humane-life individuals exhibit a tendency toward human-centered thought with respect to ethical attitudes. Conclusion. This study will be of interest to educators of students of nursing and hospital nursing administrators. Also, the findings may provide the basis for the development of more appropriate strategies to improve nursing ethics education programs.

The purpose of this study is to find out the need for sex education of middle school students and their parents. For the data collection, the survey was conducted during the period from September 10 to September 20, 1989 by using prepared questionnaire. A questionnaire was given to 592 students of 1st, 2nd and 3rd grade from four middle schools and to 408 their parents in Suwon City. The major results are summarized as follow; 1. Among the 25 questions were asked about knowledge of sex, the structure of reproductive organs, physical change during puberty, menstruation, Sexually stimulation and family plan were answered correctly by over 50% of the students. The higher the grade, the more the knowledge of sex. There was no significant difference between this knowledge and with eider sister or brother. Among the 20 questions were asked about knowledge of sex, sexually stimulation, pregnancy, emission, induced abortion and sexually transmitted disease were answered correctly by over 50% of the parents. 2. 30 questions were asked about attitude of sex, 47.7% of the students and 53.4% of the parents answered 'positive'. There was no significant difference between grade and sex of students. A significant difference '.vas not also found between years and education level of parents. 3. In case of students, experience of sex education was showed the structure of reproductive organs, physical change during puberty, temper during puberty, menstruation, emission more. In the event of parents, experience of sex education was showed the structure of reproductive organs, temper during puberty, menstruation, emission, relationship with apposite sex more. Most students felt that sex education should begin from the first grade of middle school and the first grade of high school strongly. In parents was showed the need for sex education from the primary school and the first grade of middle school highly. Namely, students and parents felt that sex education should begin from puberty. To help good developments and growth of middle school students with rapid change should be educated sex eduction properly for the occasion.

This study was carried out to establish the techniques for producing the calves of genetically superior Korean Native cattle by transfer of frozen-thawed embryos. The effects of some factors related to embryo recovery following superovulation and pregnancy rate following transfer of frozen-thawed embryos were evaluated. Also calving state was investigated. The results obtained were as follows ; The mean number of total and transferrable embryos recovered per superovulated cow was 8.72 and 4.90, respectively, from a total of 72 superovulations using 34 donor cows. There were no significant differences in the number of total or transferrable embryos recovered per superovulated cow between products of follicle stimulating hormone (FSH), years, seasons, and collection numbers. The pregnancy rate was found 44.44% following transfer of frozen-thawed embryos of Korean Native cattle to a total of 180 recipient cows including 82 Angus, 27 Charolais, 62 Hereford and 9 Korean Native cows. The pregnancy rate was significantly (P<0.05) higher in the transfer of excellent (42.99) and good embryos (40.17%), compared with fair (5.90%) grade embryos. And the pregnancy rate was significantly (P<0.05) higher in the transfer of embryos of morula stage (43.86%) than blastocyst stage (15.51%). But there were no significant differences in pregnancy rates between natural and induced estrus estrus asynchrony of 1 days, breeds, and parities of recipient cows. The normal calving rate of 80 pregnant cows following transfer of frozen4hawed em-bryos was 87.5% and the other 10 pregnant cows showed abortion during the period from pregnancy diagnosis at 50~60 days to calving. The average gestation length of normally delivered recipients was 288.50 days and the average birth weight of 70 calves born was 24.22 kg. The gestation length was significantly (P<0.05) shorter in the recipients delivering female calves (286.70 days) than males (289.39 days). But there were no significant differences in gestation tength and birth weight of calves born between the recipient breeds.
