  • Purpose: This study is to investigate the pattern of discomfort, coping style and relief level of female workers. Methods: The subjects were 394 women who worked at three general hospitals located in S city and agreed to the purpose of this study. Data were collected April 20~30, 2010, and one-way ANOVA and Pearson's correlation were performed using descriptive statistics using SAS 9.2. Results: showed that discomfort during menstruation was significantly different from age, marital status, pregnancy experience, and birth experience. The average degree of discomfort during menstruation was $2.46{\pm}0.68$, which was the average of 5, and the pattern was pain, water accumulation and behavior change. The degree of mitigation according to coping strategies was the most effective at $3.55{\pm}0.58$, and the relationship between coping behavior and discomfort during menstruation was correlated only with avoidant coping. p = .001). Conclusion: In order to mitigate the inconvenience of menstruation, women should seek to cope with their own coping strategies rather than passive coping methods and suggest the development of an educational program that can relieve the discomfort during menstruation.

  • Noninvasive techniques for antenatal detection of the fetal development and well-being such as biophysical profile, non-stress and stress test remain major challenges in modem obstetric practice. To obtain and analyze umbilical artery velocity waveform by pulsed-wave doppler ultrasound, a total of 160 determinations were carried out on 157 normal pregnant women between 16th to 41st week gestation. The ratio of peak systolic to end-diastolic flow velocity(S/D ratio), pulsatility index and resistance index were measured as indices of the resistance in feto-placental circulation. The results were as follows : As gestation advances, the, mean values for peak systolic and end-diastolic velocities raised progressively. As gestation advances, the mean values for the S/D ratio declined progressively, exhibiting high diastolic flow velocity caused by low resistance. Pulsatility index, and resistance index were also declined progressively, as gestation advances. The analysis of umbilical artery blood flow velocity waveforms provides a new noninvasive technique to evaluate fetal development and well-being, and may be expected a reliable method for assessment of fetal life.

  • Purpose: This study was conducted to explore relationships of postpartum depression with socio-demographic and clinical characteristics of preterm infants and mothers. Methods: Participants were the mothers of 80 premature infants admitted to neonatal intensive care units. Postpartum depression was measured using the Edinburg Postnatal Depression Scale (EPDS). Clinical characteristics were examined through the medical records. The physiological state for the infants was evaluated using the revised Neurobiologic Risk Score (NBRS). Data were analyzed using the t-test, ANOVA, and Pearson correlation coefficients. Results: Average for EPDS was $9.75{\pm}5.06$, and 30% of the participants were at high risk for postpartum depression. There were significant differences in postpartum depression according to mother's education level (F=3.493, p=.035), economic state (F=5.828, p=.004), multiple pregnancy (t=2.141, p=.037), chorioamnionitis (t=2.349, p=.021), oligohydramnios (t=-2.226, p=.029), broncho-pulmonary dysplasia (t=2.085, p=.040), germinal matrix hemorrhage (t=2.259, p=.027), and revised NBRS (t=-2.772, p=.007). There was a significant positive correlation between postpartum depression and number of health problem of infants (r=.252, p=.024) and revised NBRS (r=.316, p=.004). Conclusion: As 30% of the mothers with preterm infants were at high risk for postpartum depression, they require attention. When providing interventions, socioeconomic status as well as the physiological state of premature infants should be considered.

  • The authors of the present study report the prenatal detection of a chromosomal abnormality with additional satellites on the distal short arm of chromosome 8. A 35-year-old woman was referred for amniocentesis because of her advanced maternal age and positive result for maternal serum screening test. Cytogenetic analysis of cultured amniocytes showed a satellite 8p chromosome. The satellite 8p chromosome was positive for nucleolus organizer region (NOR) staining. The parents' karyotypes were normal. Fluorescence in situ hybridization (FISH) study for metaphases of fetal amniocytes revealed a cryptic translocation of chromosomes 8p and 22p. The fetal karyotype was described as 46,XY,8ps.ish t(8;22)(p23.3;p11.2) (D8S504-;D8S504+)dn. The parents decided to continue the pregnancy and a phenotypically normal boy was born at 38 weeks of gestation. In case of de novo terminal NORs detected prenatally, more accurate cytogenetic and molecular analysis should be performed in order to rule out cryptic chromosomal rearrangement among other chromosomes.

  • Mongolia has 80% livestock of total agriculture industry, 170,000 farms are engaged, 2,500,000 of cows that were beef and dairy cows are raised. Despite of Mongolian has great application with milk, there are not clear differences between cow and dairy cattle, and the production of milk is also low. But the milk suppliers are varied (horse, sheep, goat, etc), so that the total milk production is 500 thousand ton per year. It's really considerable to improve the breed of owing to many problems with big differences among milk qualities. For carrying out for first year project, artificial insemination project was operated with 3rd grade Holstein semen that were imported from S. Korea, and initiation and field training were also carried out through appropriate AI technique we developed for Mongolia environment. Local information research and MOU conclusion were done with professor D. Altangerel in May $10^{th}{\sim}13^{th}$, 2009, and development for AI technique and AI equipments were supplied for Mongolia breeding and natural environment in July $10^{th}{\sim}17^{th}$ in 2009. All cows were treated by synchronization for AI. To do this, $PGF_{2\alpha}$ injection were treated for luteal phase cow, if it wouldn't work, try again after 11 days. After confirmation of estrus, AI and AI training were carried out with sperm injection in the uterus or cervix by rectum-vagina method which is common worldwide, the most effective artificial insemination technique. If cows were return to next estrus cycle, second AI was carried out about approximately 21 days after artificial insemination. After 2 months, all cows not showing return estrus should be taken pregnancy test. Every pregnant cow will be cared thoroughly. Total 48 cows administrated by $PGF_{2\alpha}$ for synchronization and after 48 hours 45 cows (93.8%) showing estrus were detected and then artificial inseminate them within who 8 cows (27.8%) showed return estrus. Therefore, Using $PGF_2{\alpha}$ for synchronization is effective to use for Mongolia breeding conditions. There are possibility of base for food production after all, including increase of livestock production in Mongolia by improvement of breeding cow with AI and embryo transfer project.

  • The present study was carried out to sex effectively mouse and rabbit embryos using rat H-Y antiserum and to improve the rate of rat producing H-Y antiserum with H-Y antibody. The H-Y antiserum was prepared from inbred SD strain female rat immunized by intrasplenic injection and subsequent intraperitioneal booster of testis cell of syngenic male newborn rat. the titer of antiserum was identified by in vitro cytotoxicity test of mouse embryos. The rabbit embryos exposed to the H-Y antiserum was classified to the developed (H-Y negative) or delayed (H-Y positive) group. The H-Y negative rabbit embryos were transferred to recipients and sex of offspring was examined. 1. When mouse embryos were exposed to the rat H-Y antisera, the ratio of embryos developed vs delayed was various. The H-Y antisera where the ratio of embryos developed vs delayed showed the range of 40~60% were recognized as having titer of H-Y antibody. 2. When the subsequent intraperitioneal boosters were followed after priming of intrasplenic injection of H-Y antigen, the rate of rat producting the H-Y antiserum with H-U antibody was 13, 27, 70 and 73% in control, 1st B, 2nd B and 3rd B, respectively. The rate in 2nd B and 3rd B was significantly(P<0.05) higher than that in control and 1st B. 3. When the rabbit morulae were exposed to the rat H-Y antiserum with H-Y antibody, the ratio of morulae developed versus delayed was 42:58% and it was close to the natural sex ratio 50:50%. It was confirmed that the rat H-Y antiserum was cross reactive to the rabbit morulae. 4. When the H-Y negative rabbit embryos were transferred to the recipients, the pregnancy rate was 50% and 83% of the newborns were females. In conclusion, the rat H-Y antiserum with high titer of H-Y antibody was able to be obtained from the female rat immunized by the intrasplenic injection followed by the second intrapent oneal booster of testis cells at a week interval. When the rabbit embryos negative to the rat H-Y antiserum were transferred, 83% of the newborns were females.

  • A 36-year-old pregnant woman was referred for amniocentesis at 19.5 weeks gestation because of advanced maternal age and evidence of increased risk for Edward syndrome in the maternal serum screening test. Cytogenetic analysis of the cultured amniotic fluid cells revealed mosaicism for ring chromosome 11: 46,XX,r(11)[65]/ 45,XX,-11[16]/ 46,XX [34]. Parental karyotypes were normal. A targeted ultrasound showed intrauterine grow th restriction (IUGR). Cordocentesis was performed to characterize the ring chromosome and to rule out tissue specific mosaicism. Karyotype was confirmed as 46,XX,r(11) (p15.5q24.2)[229]/45,XX,-11[15]. And a few new form of ring w ere detected in this culture. The deletion of subtelomeric regions in the ring chromosome were detected by fluorescent in situ hybridization (FISH). The pregnancy was terminated. The fetal autopsy showed a growth-retarded female fetus with rocker bottom feet. We report a case of prenatally detected a de novo ring chromosome 11.

  • The safety of ICSI as a novel procedure of assisted fertilization may be assessed by the health of the baby born. In order to evaluate the safety of ICSI, perinatal outcome and congenital anomaly of the babies born after ICSI were compared with those of babies born after IVF (control group). We analysed the clinical data from the obstetric and pediatric records, including the information obtained through telephone. The results are as follows; Mean gestational age $({\pm}SEM)$ and birth weight in singleton pregnancy were $38.8{\pm}1.9$ weeks and $3209.7{\pm}501.9gm$ in IVF group, $39.0{\pm}2.2$ weeks and $3289.9{\pm}479.5gm$ in ICSI group, respectively. Mean gestational age and birth weight in twins were $36.8{\pm}2.1$ weeks and $2512.8{\pm}468.0gm$ in IVF group, $36.5{\pm}2.8$ weeks and $2492.7{\pm}537.1gm$ in ICSI group. In IVF group, perinatal mortality rates were 8.5 in singletons and 56.6 in twins; for the ICSI singletons and ICSI twins, the perinatal mortality rates were 11.6 and 49.0, respectively. The incidence of congenital malformations was 3.6% (8/224) in IVF group and 2.1% (4/188) in ICSI group, there was no statistical difference (p>0.05, Fisher's exact test). The incidence of major congenital anomalies was 0.9% (2/224; pulmonary artery hypoplasia, renal cystic dysplasia) in IVF group and 1.1% (2/188; holoprosencephaly, Cri du chat syndrome) in ICSI groups (p>0.05, Fisher's exact test). Similarly, there was no significant difference in incidence of minor congenital anormalies 2.7% (6/224) in IVF group and 1.1% (2/188) in ICSI group respectively (p>0.05, Fisher's exact test). In conclusion, there was no difference in the perinatal outcome and the incidence of congenital anomalies between the babies born after ICSI and those after conventional IVF.

  • The purpose of this study was to compare the effects on labor pain and duration of delivery time for primipara women treated by Hob-Gog (LI-4) pressure. 1. The proposed hypothesis was that 'the score of labor pain could be lower in the group which had LI-4 pressure applied than in the control group'. 1-1. The sub hypothesis was that the score of subjective labor pain would be lower in the group which had LI-4 pressure applied than in the group which did not have LI-4 pressure applied. 1-2. Another sub hypothesis was that the score of objective labor pain would be lower in the group which had LI-4 pressure applied than in the group which did not have LI-4 pressure applied. 2. The proposed hypothesis was that 'the score of duration of delivery time could be shorter in the group which had LI-4 pressure applied than in the control group'. The design of this study was a nonequivalent control group non-synchronized post test only design to verify the effect on labor pain for primipara women treated by LI-4 pressure and to evaluate the benefits of using LI-4 pressure on some women and judging the degree of their labor pains in comparison with other primipara women not treated with LI-4 pressure. The subjects included 63 primipara women who underwent vaginal delivery, who were between 38-41 weeks intra uterine pregnancy; who did not have any complications; and who were under pitocin augmentation or induction. They were recruited with informed consent; 34 were in the control group and 29 were in the experimental group. The study was measured with a structured questionnaire consisting of general characteristics, knowledge related to delivery, subjective (Johnson, 1974) and objective(McLachlan, 1974) labor pain scale, data collection was done by research during the period from April, 2000 to July, 2000 and data was analyzed by descriptive statistics, $x^2$-test, and t-test. The results were as follows: 1. The scores of total labor pain in the group which had LI-4 pressure applied were lower($347.62{\pm}49.84$) than in the group($411.02{\pm}55.79$) which did not have LI-4 pressure applied; And these differences were statistically significant(t=4.7193, p=.000). 1-1. The scores of subjective labor pain in the group which had LI-4 pressure applied were lower($203.44${\pm}33.88$)$ than in the group ($$233.82{\pm}31.31$$) which did not have LI-4 pressure applied(t=3.6953, p=.000). 1-2. The scores of objective pain in the group which had LI-4 pressure applied were lower ($144.18{\pm}29.12$) than in the group which did not have LI-4 pressure applied($177.20{\pm}35.01$). but there were no statistically significant differences found in regard to the scores of objective pain(t=4.0271, p=.000). 3. The duration of delivery time in the group which had LI-4 pressure applied was shorter ($390.51min{\pm}111.91$) than in the group ($460.44min{\pm}190.78$)which did not have LI-4 pressure applied and the duration of delivery time in the experimental group was statistically more significant than that in the control group. therefore this thesis was adapted(t=1.734, p=.0879). It could be concluded that LI-4 pressure is effective in relation to labor pain and duration of delivery time for primipara women. Therefore it is necessary to increase the number of subjects to generalize this result.

  • Embryos and fetuses are more sensitive to various environmental agents than are adults or children. The biological effects such as intrauterine death and malformation are closely connected with prenatal exposure very various agents. The sensitivity of these embryonic/fetal effects depends on the stage of pregnancy. From the viewpoint of fetal development, embryonic and fetal stages can be divided into three stages : Preimplantation, organogenetic and fetal. Each stage corresponds to 0 to 4.5days, 4.5 to 13.5days, and 13.5days of gestation in mice, respectively. Many studies on the biologcal effects of mice irradiated by ${\gamma}-rays$ at various stages during organogenesis and fetal period have been performed. Based on these results, the dose-effect and dose-response relationships in malformations, intrauterine death, or retardation of the physical growth have been practically modeled by the ICRP(International Commission on Radiological Protection) and other international bodies for radiation protection. Many experimental studies on mice have made it clear that mice embryos in the preimplantation period have a higher sensitivity to radiation for lethal effects than the embryos/fetuses on other prenatal periods. However, no eratogenic effects of radiation at preimplantation stages of mice have been described in many textbooks. It has been believed that 'all or none action results' for radiation of mice during the preimplantation period were applied. The teratogenic and lethal effects during the preimplantation stage are one of the most important problems from the viewpoint of radiological protection, since the preimplantation stage is the period when the pregnancy itself is not noticed by a pregnant woman. There are many physical or chemical agents which affect embryos/fetuses in the environment. It is assumed that each agents indirectly effects a human. Then, a safety criterion on each agent is determined independently. The pregnant ICR mice on 2, 48, 72 or 96 hours post-conception (hpc), at which are preimplantation stage of embryos, were irradiated whole body Cesium-gamma radiation at doses of 0.1, 0.25, 0.5, 1.5, and 2.5 Gy with dose rate of 0.2 Gy/min. In the embryos from the fetuses from the mice irradiated at various period in preimplantation, embryonic/fetal mortalities, incidence of external gross malformation, fetal body weight and sex ratio were observed at day 18 of gestation. The sensitivity of embryonic mortalities in the mice irradiated at the stage of preimplantation were higher than those in the mice irradiated at the stage of organogenesis. And the more sensitive periods of preimplantation stage for embryonic death were 2 and 48 hpc, at which embryos were one cell and 4 to 7 cell stage, respectively. Many types of the external gross malformations such as exencephaly, cleft palate and anophthalmia were observed in the fetuses from the mice irradiated at 2, 72 and 96 hpc. However, no malformations were observed in the mice irradiated at 48 hpc, at which stage the embryos were about 6 cell stage precompacted embryos. So far, it is believed that the embryos on preimplantation stage are not susceptible to teratogens such as radiation and chemical agents. In this study, the sensitivity for external malformations in the fetuses from the mice irradiated at preimplantation were higher than those in the fetuses on stage of organogenesis.
