The effect of GnRH and/or hCG on the implantation, pregnancy, and the concentration of plasma estradiol and progesterone were studied in pregnant rats. GnRH 50, or 100ug and/or hCG 50 or 100 IU were administered once on day 2 or 9 of gestation, respectively. Rats were autopsied on days 8 or 16. Administration of GnRH on day 2 did not induce the prevention of implantation and termination of pregnancy but was able to induce termination of pregnancy administering on day 9. Administration of hCG induced delayed implantation on day 2 and termination of pregnancy on day 2 and 9. Administration of GnRH concomitant with hCG had no effect on prevention of implantation on day 2 but induced termination of pregnancy with a very increased fetal resorption on day 2 and with a moderate increased fetal resorption on day 9. Administration of GnRH concomitant with hCG on day 2 induced more increased termination of pregnancy compared to injection of GnRH or HCG and opposite result was observed on day 9. Plasma estradiol and progesterone concentrations by administering GnRH and/or hCG had no effect on the termination of pregnancy the pregnant rats.

The effects of PMSG and/or prostaglandin analogue, cloprostenol, on the prevention of implantation, termination of pregnancy, concentration of plasma progesterone, and Na and K contents of the plasma and uterine fluid were studied in pregnant rats. PMSG 50 or 100 IU concomitant with cloprostenol 90 or 180 mg were administered once on day 3 or 9 of gestation. Rats were autopsied on days 8, 10 or 21 gestation. A single administration of PMSG resulted in increasing the number of corpora lutea, preventing implantation and terminating pregnancy. A single administration of cloprostenol had no effect on the prevention of implantation and termination of pregnancy but was able to induce the termination of pregnancy administering at large doses on day 9. A single administration of PMSG concomitant with cloprostenol ws found to be very increased the number of corpora lutea and to be 100% effective in preventing implantation and to be nearly 100% effective in terminating pregnancy. It is uncommon that a single dose of PMSG 50 IU concomitant with cloprostenol 90 or 180 mg on day 9 was able to maintain the pregnancy at very low rates of 0.3∼5.3%. Concentration of plasma progesterone and Na and K contents of the plasma and uterine fluid were increased or decreased administering PMSG and/or cloprostenol, but had no effect on preventing implantation and terminating pregnancy.

The effect of GnRH alone and concomitant with PMSG on the prevention of implantation. termination of pregnancy, and concentration of plasma progesterone were studied in pregnant rats. GnRH 50, 100 or 200 ug alone and concomitant with PMSG 25 or 50 IU were administered once on day 2 or 9 of gestation, respectively. Rats were autopsied on days 7 or 20. Administration of GnRH on day 2 did not result in the prevention of implantation and termination of pregnancy but resulted in termination of pregnancy administering on day 9. Administration of GnRM concomitant with PMSG on day 2 or 9 resulted in prevention of implantation and termination of pregnancy, but injection of GnRH 50 ug concomitant with PMSG 25 IU on day 9 had only one live fetus. Administration of GnRH alone and concomitant with PMSG on day 2 had no effect on the concentration of plasma progesterone determining on day 7. Administration of GnRH concomitant with PMSG on day 2 resulted in decrease of progesterone level determining on day 20 but GnRH alone was normal level. Administration of GnRH alone and concomitant with PMSG on day 9 resulted in decrease of the concentration of progesterone but was normal concentration administering GnRH 50 ug concomitant with PMSG 25 IU.

The effect of Human Menopausal Gonadotropin(hMG) on the implantation, pregnancy, and the concentration of plasma progesterone were studied in pregnant rats. HMG 75 or 150 IU were administered once on day 1, 2, 3, 4, 9, 12 or 14 of gestation, respectively. Rats were autopsied on day 7 or 18. A single dose of hMG prevented implantation and terminated pregnancy in all of the rats by injecting on either day 1 or day 2 and this abortifacient action was effective 82-98% of pregnant rats on day 3 or 4 and 14-20% on day 9 or 12. Administration of hMG had no effect on termination of pregnancy on day 14. Plasma progesterone concentration by injecting hMG on day 1, 2, 3 or 4 were very decreased.

The present analysis was undertaken to find out the relationships between birth weight & Apgar Score of newborn infant & maternal factors. The medical records of 1436 newborn infants who had been at the Korea University III Seoul from January. 1.1984. to December. 31. 1985, were examined. Measurements include weight and Apgar Score. As the possible factors influencing the birth weight & Apgar Score of newborn infant, 9 variables such as : mother's age, frequency ·of pregnancy, frequency of fullterm delivery, frequency. of premature, frequency of abortion, mother's hemoglobin level, complications during pregnancy gestational period and infant sex at birth were selected among the items recorded in the medical records of newborn infants and their mothers. The weight & Apgar Score of newborn infants were compared separately by sex with group percent of those variables. The results were summarized as follows: 1. All of those factors chosen are supposed to be influencing upon the birth weight and Apgar Score examined at birth indirectly through inducing early termination of pregnancy. 2. The most influencing variable of birth weight of newborn infants was gestation period. The most influencing variable of Apgar Score of infant newborn was gestation period. 3. The relationships of those influencing factors are more clear on the birth weights of newborn than on the Apgar Score. 4. More then half of low birth weight infants are turned out to be physiologically normal through the evaluation by Apgar Scoring. Conclusively, All of those factors chosen are supposed to be influencing upon the birth weight and apgar score examined at birth indirectly through inducing early termination of pregnancy.

Peritoneal pregnancy is an implantation in the peritoneal cavity exclusive of tubal, ovarian, or intra-ligamentary implantations. This is a rare obstetric complication with high maternal mortality and even higher perinatal mortality, and secondary type was most common. Risk factors for peritoneal pregnancy are previous history of extrauterine pregnancy or tubal surgery pelvic post-inflammatory status or presence of an intrauterine device. As it is a life-threatening condition, expectant management carries a risk of sudden life-threatening intra-abdominal bleeding and a generally poor fetal prognosis. So, when it is recognized, immediate termination of pregnancy is usually recommended. Early diagnosis of peritoneal pregnancy is difficult, but is important by their life threatening progress course to patients. Recently, we experienced primary peritoneal pregnancy which meets both the original and modified criteria. In this paper, we reported the case of early diagnosed and successfully treated peritoneal pregnancy despite of their diagnosis was incidentally.

The thalidomide tragedy in the 1960s has resulted in a perpetuation of a certain perception amongst physicians and pregnant women that the use of medication during pregnancy is a potential teratogen. Consequently, physicians hesitate in prescribing medication to pregnant women. In addition, pregnant women often refuse medication despite therapeutic necessity because of this existing perception. Recently there have been frequent adverse pregnancy outcomes related to the recurrence of chronic diseases, such as hypertension and diabetes, following pregnancy in older women. And there are lots of unnecessary termination of pregnancy due to the of information of medication exposed to medication following over 50% of unintended pregnancy. In light of this, better dissemination of information regarding the safe usage of medication for pregnant women is required. This would not only be cost-effective in terms of medical expenditure, but also prove beneficial for the treatment of diseases. In addition, Korea needs to adapt to the increasing changes of the international information system regarding supporting the safe usage of medication during pregnancy. An example of this is shown by the recent changes to the labeling of medication by the United States Food and Drug Administration. The new labeling includes information on the risk of usage, rather than just an arbitrary alphabetic classification of B, C, D, or X. Furthermore, this information is limited in Korea because of the lack of research, which in turn is due to several limitations on ethics and methodology, as well as present regulations on the research of pregnant women. From this, we can learn that government support is critical for the establishment of research so that we can alter the perception that all medication is harmful to pregnant women.

A congenital fistulous communication between the coronary artery and the cardiac chamber or the pulmonary artery is a rare condition, but increasing cases with this anomaly are being recognized with wide spread use of cardiac catheterization and coronary arteriography. Recently we experienced one case of right coronary artery fistula which was associated with atrial septal defect. The patient was a 24 year old female who was admitted because of cardiac murmur, palpitation and dyspnea on exertion after pregnancy. Cardiac catheterization and selective coronary arteriography revealed that a fistulous communication, forming a large aneurysm, was noted from the right coronary artery emptied into the right ventricle. On the operation field, the right coronary artery was curved and markedly dilated from the aorta to the middle segment at acute margin of the right ventricle. The egg-sized aneurysm of dilated right coronary artery was noticed on right ventricle. The aneurysm was incised longitudinally and both the proximal opening and the termination site of the fistula were closed directly with aneurysmectomy. The right atrium was also opened to evaluate the fistulous termination site and repaired only small interatrial septal defect. Postoperative course was uneventful and she was discharged without problems

Purpose: The purpose of this study was to investigate the research methods, topics and trend in reproductive health on women in Korea. Method: We reviewed 102 studies from the electronic database of KISS, RISS, NDSL, and PubMed, and finally selected 13 studies based on relevant criteria. Result: With regard to research methods, the majority of studies used survey research. As for the research themes, reproductive health status was most common. For study results, knowledge status of pregnancy and contraception were higher in university students. High school female students' level of sexual awareness was higher than that of male students. Around 30% of college students experienced direct sexual behavior. Ten percent of college students who had sexual experience had an unplanned pregnancy. About half of married women had experienced artificial termination of pregnancy at least once. Conclusion: The results of this study provide a basis for the improvement of women's reproductive health.

Purpose: There has been a considerable increase in the number of women giving birth at advanced age. The genetic screening of such women is highly desirable. Clinical nurses, however, are not adequately trained to assist such clients. This study aims at identifying the educational needs of nurses in order for them to provide better care and treatment for such women. Methods: 206 South Korean clinical nurses participated in this study. Study variables were measured by nurses' attitudes toward terminating pregnancy (ATP), knowledge of prenatal genetic screening and diagnosis (K-PGSD), and information needs for prenatal genetic screening and diagnosis (I-PGSD). The statistical analysis included T-test, analysis of variance and Pearson's Correlation Coefficient. Results: Mean scores were 34.57±5.73 for ATP, 16.44±3.04 for K-PGSD, and 78.81±10.95 for I-PGSD. The findings demonstrate that nurses have high information needs (I-PGSD) to take better care of women who have positive results from their amniocentesis tests. Conclusion: Information needs among clinical nurses are not currently being met. Education for nurses must include training in counseling to encourage patients' autonomous decision-making regarding their pregnancies.
