Controlled Ovarian hyperstimulation(COH) is generally used to obtain synchronous high quality oocytes in in vitro fertilization-embryo transfer(IVF-ET). Many investigators have studied the relationship between serum hormone levels and outcomes of IVF-ET because there is no accurate estimation method of oocyte quality. Early premature luteinization of follicles before oocyte retrieval is the most troublesome problem in COH for IVF-ET. Gonadotropin-releasing hormone agonists(GnRH-a) are used as adjuncts with gonadotropins for COH in patients undergoing in IVF. The possible benefits of GnRH-a pretreatment include improving oocyte quality, allowing a more synchronous cohort of follicles to be recruited, and preventing premature lueinization hormone surges. In COH of IVF cycles, we investigated whether an elevated progesterone(P4) level on the day of human chorionic gonadotropin(hCG) administration indicates premature luteinization and is associated with a lower fertilization rate. Many investigators have studied that the lower fertilization rates seen in patients with elevated P4 levels might result from an adverse effect of P4 on the oocytes. We hypothesizes that serum P4 levels around the day of hCG may be helpful prediction of out come in IVF-ET cycles. Success rates after COH of IVF-ET cycles are dependent upon many variable factors. Follicular factors including the number of follicles, follicular diameters and especially serum estradiol(E2) levels as an indirect measurement of follicular function and guality have been thought to influence the outcomes of IVF-ET. To assess whether serum P4 and E2 levels affect the fertilization and pregnancy rate, we reviewed the stimulation cycles of 113 patients (119 cycles) undergoing IVF-ET with short protocol with GnRH-a, from March 1993 to August 1994 retrospectively. The serum P4 and E2 levels were compared on the day of hCG in the pregnant group, 45 patients(47 cycles) and in the non-pregnant group, 68 patients (72 cycles) respectively. The serum E2 level in non-pregnant group was $1367{\pm}875.8$ pg/ml which was significantly lower than that of pregnant group, $1643{\pm}987.9$ pg/ml( p< 0.01 ). And the serum P4 level in non-pregnant group was $2.1{\pm}1.4$ ng/ml which was significantly higher than that of pregnant group, $1.0{\pm}0.7$ ng/ml( p< 0.001 ). The fertilization rate was $61.3{\pm}21.3%$ in pregnant group which was higher than that of non-pregnant group, $41.1{\pm}20.2%$ (p< 0.01). We suggest that the serum levels of P4 and E2 on the day of hCG administration are additional parameters that predict the outcomes of IVF-ET cycles.

Objectives : The change of sleep patterns commonly occurs in association with the pregnancy. This study was to investigate sleep habits during the course of normal pregnancy. Methods : Sleep habits questionnaire was administered to healthy women in their first trimester(TR1) of pregnancy and then the same questionnaire was repeatedly administered during their second(TR2) and third(TR3) trimesters. The following aspects were assessed : patterns of night sleep, daytime status, sleep posture, reasons for sleep alteration, and the experience of any particular parasomnias, as well as sleep problem-related treatment or medication. Data analysis was based on 26 women who maintaind good health throughout their pregnancy and completed the questionnaire three times. Results : In comparisons between each trimester and non-pregnant state, total night sleep time, daytime tiredness, and sleepiness were significantly increased in all trimesters. Sleep latency was significantly decreased in TR1 and TR2, but not in TR3. In addition, refreshed feeling on waking the following day was significantly decreased and the number of awakenings during night sleep was significantly increased in TR3, but not in TR1 and TR2. In comparisons between trimesters, there was a significant increase in sleep latency, daytime sleepiness and the number of awakenings during night sleep and a significant decrease in refreshed feeling on waking the following day in TR3 compared to TR1 and TR2. Over the course of pregnancy, the rate of lateral position during sleep was gradually increased and all the pregnant women took the lateral sleeping posture in TR3. The major reasons for sleep pattern alteration were nausea, vomiting and heartburn in TR1, urinary frequency, fetal movement and ache in hips in TR2, and urinary frequency, fetal movement, cramp in legs and backache in TR3. Conclusion : These findings are expected to be useful for educating pregnant women about sleep hygiene. In future studies, the underlying factors and mechanisms regarding sleep patterns during pregnancy will need to be clarified.

Purpose: The purpose of this study was to look into back pain, pain disability, labour pain, and related areas of pain experienced by postpartum women. Method: A survey about pain including a Visual Analogue Scale (VAS), Oswestry pain disability, and pain drawing was used in a descriptive research method on 98 women 2-3 days after delivery. Result: 57.1% of those surveyed reported experiencing back pain before pregnancy. 75.5% reported experiencing back pain during pregnancy. The average starting time of back pain for pregnant women was 2.9 months into pregnancy. 48.8% reported the most severe back pain in the last trimester of pregnancy, while most women complained of left and right pubic pain and lumbar area pain during pregnancy. Statistical relations were calculated and menstrual symptoms (F=5.938, p=0.004), back pain prior to pregnancy (F=4.714, p=0.000), back pain during pregnancy (F=-3.429, p=0.001), and back pain disability prior to pregnancy (F=-1.994). Conclusion: There is a relation in postpartum women's back pain between back pain prior to pregnancy and back pain during pregnancy. Pelvic examinations early in pregnancy can determine if back pain will change for the worse or relapse. Therefore, the application of a pain relieving nursing intervention is needed.

Retroperitoneal ectopic pregnancy is a rare form of ectopic pregnancy. Owing to its rarity and nonspecific symptoms, diagnosing retroperitoneal ectopic pregnancy at the initial presentation poses a significant challenge. Typically, the diagnosis relies on non-radiation imaging modalities, such as ultrasonography and MRI, whereas CT is infrequently used. Herein, we report a rare case of a retroperitoneal ectopic pregnancy, which was diagnosed using CT.

The purpose of this study was to investigate the risk factors of pregnancy and the relationship between pregnancy experience and suicidal behavior in 284 pregnancy experienced adolescents aged 13-19 years. The suicidal ideation was 57.8%, the suicide plan was 37.7% and the suicide attempt was 37.3% among female adolescents with pregnancy experience. By multivariate logistic regression analysis, female adolescents who experienced pregnancy had 1.44 times more suicidal ideation, 2.39 times more suicide plans, and 2.38 times more suicide attempts than those without suicidal thoughts, plans and attempts. Because of the high correlation between pregnancy experience and suicidal behavior in female adolescents, school and education authorities need systematic education and countermeasures to prevent adolescents' pregnancy and risk of suicide after pregnancy. And above all, convergent support and interest in home, school and community comprehensive area should be supported.

Purpose: Pregnancy in transplanted mother is considered as a high-risk pregnancy, and significant incidences of prematurity and low-birthweight(LBW) infants have been reported. The objective of this study is to examine the outcome of pregnancy in transplanted mothers and to evaluate the current growth status in their children. Patients and Methods: We retrospectively reviewed 54 pregnancies in 40 kidney recipients until June 1999. Outcomes of pregnancy were reviewed and assessment of the current growth status in children was performed. Results: 54 pregnancies in 40 recipients were identified; 22 ended in termination of pregnancy because of unwanted pregnancy or therapeutic purposes. And of the other 32, 29 livebirths resulted in 28 recipients. The mean age of conception was $30.3{\pm}3.8$ years, with a mean interval from transplantation to conception of $35.9{\pm}23.2$ months. All patients were maintained on immunosuppressive regimens. Incidence of drug-treated hypertension(HTN) prior to pregancy was $52\%$, HTN during pregnancy, $48\%$; preeclampsia, $41\%$; urinary tract infection, $48\%$; oligohydramnios $4\%$; and no rejection during pregnancy and up to 3month post delivery. Of the 29 liveborn infants, prematurity(<37wk) occurred in $52\%$, LBW(<2500g) in $62\%$, VLBW(<1500g) in $7\%$ and $48\%$ born intrauterine growth retardation(IUGR). Mean gestational age was $36.3{\pm}3.0\;wk$; a mean birthweight, $2.23{\pm}0.6\;kg$; a mean birth-height, $45.1{\pm}3.6cm$. Current mean height standard deviation score (height SDS) was $0.29{\pm}0.91$ and mean weight SDS was $0.62{\pm}1.34$. Only one child($4\%$) under 1 year of age was below 10 percentile in height. Most of children had no medical problems except for 4 children; cleft palate(1), tuberous sclerosis(1), essential hematuria(1), and one child expired due to sepsis. Conclusion: This study showed similar incidence of premaure birth($57\%$) and low birth weight infants($62\%$), but lower incidence of spontaneous abortion($5.6\%$) was observed and compared to other studies. Postnatal growth in majority of children($96\%$) achieved catch-up growth before 1 year. Present study supports a more optimistic view of pregnancy in renal transplant mother and normal growth in their children.

For the comparative study of protein patterns of the sera of pregnant women, the protein in sera of normal male subjects, non-pregnant women, pregnant women and women delivered of children were analyzed by using the methods of SDS/polyacrylamide gel electrophoresis, two-dimensional electrophoresis and amino acid analysis. The results were as follows: 1. When the protein patterns of sera in normal male ranging from 10, 000 to 110, 000 daltons were compared to non-pregnant women by SDS/polyacrylamide gel electrohporesis, their protein patterns were same each other numerically but bands 3(22, 000 dalton) and 6(39, 000) were less in male than in non-pregnant women quantitatively. When the protein patterns in the pregnant women in which serum were collected two week intervals were compared with non-pregnant women, there was increased or decreased in several bands quantitavely. The protein patterns of sera in pregnant women were compared with those of non-pregnant women; band 3(22, 000) showed similar patterns each other until the 16th week but the quantity of protein was decreased continously from the 18th week to the third trimester of pregnancy. Contary, bands 4(24, 000), 9(69, 000), 10(70, 000), 12(80, 000), 14(86, 000), 15(91, 000) and 16(94, 000) were gradually increased in quantity from the begining of gestation, and band 7(51, 000) was increased until the 32th week of gestation only but somewhat decreased after this time. The quantities of bands 12(80, 000), 15(91, 000) and 16(94, 000) were relatively increased when the protein patterns of delivered women were compared with those of the third trimester of pregnancy. Women who were dilivered female children showed more increase in bands 4(24, 000), 7(51, 000) and 10(70, 000)than one who were delivered male chilren. 2. When the protein patterns of sera in normal males were compared with those of nonpregnant women by two-dimensional electrophoresis, three spots of spot a group were not appeared in the males and the spot c group in the males was less than in the non-pregnant women. In the pregnant women, albumin was significantly decreased during the 10-12 week of gestation but recovered after these times. And spot f(70, 000) was decreased in the 10th week of gestation but increased from this time. 3. Glutamic acid, lysine, aspartic acid, leucine and valine in pregnant women were large in quantity while methionine, isoleucine and glycine were small in quantity by amino acid analysis. The total amino acids were increased remarkably in the second trimester of pregnancy but began to decrease in the third trimester of pregnancy. As mentioned, this present paper deat with that proteins which consist of maternal serum were increased with specific period in pregnancy and that the change of characteristic protein patterns were identified in the serum protein of each trimester in the pregnant women. And furthermore, the study should be preformed for the sex-identification of a fetus in the early pregnancy.
