  • This study was carried out to establish an effective system for embryo transfer techniques by analyzing several factors affecting in-vivo embryo transfer in Korean cattle. Embryos produced in-vivo were transferred into a total of 301 recipients The results obtained in studies on the factors affacting pregnancy rate after embryo transfer by condition of recipients were as follows ; 1. The pregnancy rate by age and parity of recipients showed high in 5~8 and over 12 years old(72.7~73.9%), and 3rd~4th parity(82.1%) for fresh embryos(P<0.05). The pregnancy rate did not differ by age and parity of recipients in frozen embryos. The pregnancy rate of frozen embryos tended to be similar to that of fresh embryos(38.5% and 25.0~36.7%). 2. The number of observation for normal estrus cycles of recipients did not differ In pregnancy rate between one and 2 times in fresh embryos(64.9%, 69.8%). The pregnancy rate by transferred frozen embryos showed significantly higher after 2 times of observation(P<0.05, 16.3%, 37.5%). The pregnancy rate by days open did not differ between fresh and frozen embryos. But the pregnancy rate was slightly higher in 12 months and 6 months of days open for fresh and frozen embryos, respectively(70.1~71.1% and 24.5%, respectively). 3. The pregnancy rate of transferred fresh and frozen embryos into right and left side of uterine horn did not differ(62.1% : 65.9% 25.0% : 24.3%, respectively). The pregnancy rate by the grade of CL was not different in fresh embryos, but the pregnancy rate was significantly higher in the grade A than B for frozen embryos(P<0.01, 43.2%, 16.2%).

  • To investigate the estrual changes of ovaries, appropriate time of mating, diagnosis of early pregnancy after mating, and diagnosis of twin fetuses, ultrasonography was performed in 61 thorough-bred mares (5-12 years old) which had been raised in Chrju island. The followings are the results obtained: 1. The average size of a follicle of mares was $3.2{\times} 3.8cm$ at the beginning of estrus and $4.2{\times} 3.5 cm$ from the middle of estrus to ovulations respectively, and the average size of a follicle and a corpus luteum was $1.8{\times} 1.4 cm and 3.1{\times}2.3 cm$ in the middle of diestrus, respectively. 2. In the result of pregnancy according to mating time after ultrasonographic examination of follicle size, the mares having a follicle of 4.6-5.0 cm (diameter) were mated on the day of ultrasonographic examination or the next day rind all were conceived (3 mares) and another mares having a follicle of 4.1- 4.5cm (diameter) on the 1st or 2nd day after examination and all were conceived (4 mares). 3. By ultrasonographyi early pregnancy in the mares was diagnosed from 12 days of pregnancy and the equine fetus was directly detectable from 23 days of pregnancy, whereas the heartbeat of a fetus was detectable from 28 days of pregnancy. 4. Diagnosis of earl pregnancy of twin was possible from 16 days of pregnancy. These result indicated that ultrasonography is applicable in mares to diagnose the estrual changes of ovaries and the time of ovulation or mating, and to diagnose early pregnancy from 12 days of pregnancy and early pregnancy of twin fetuses.

  • Purpose: The purpose of this study was to investigate the association between maternal knowledge and social support on pregnancy stress among pregnant women in Korea. Methods: The participants in this study were 148 pregnant women in Korea, recruited from online communities on pregnancy and/or childbirth, from June 2019 to April 2020. The collected data were analyzed using the independent t-test, one-way analysis of variance, Pearson correlation coefficient, and multiple regression. Results: Participants were at average 18.25±8.28 weeks gestation, 56% were in the second trimester, 31% had one or more health issues in the current pregnancy (e.g., hyperemesis gravidarum), and 76% were first-time mothers. Participants had moderate levels of pregnancy stress (mean, 23.09±7.11 points out of 48) and maternal knowledge (mean, 14.42±4.67 points out of 21), whereas social support was somewhat high (mean 45.88±7.81 points out of 60). Pregnancy stress was weakly negatively correlated with social support (r=-.37, p<.001). Main source of pregnancy information (β=-.21, p=.011), marital satisfaction (β=-.18, p=.036), and social support (β=-.19, p=.038) were identified as significant factors affecting pregnancy stress, and these variables had an explanatory power of 22.7% for pregnancy stress. Conclusion: Based on these findings, nurses should assess pregnancy-related stress during pregnancy and consider main source of pregnancy information and marital satisfaction when providing education or counseling. Moreover, strategies to reduce pregnancy stress through social support are needed to improve the quality of life for pregnant women.

  • From old times, we think it is very important to become pregnancy with child and to give birth healthy, as the human gives not just body but also spirit. When we judge pregnancy, we usually check lady's menstrual cycle. But it is too difficult to diagnosis as pregnancy only check that. Therefore feeling pulse has been made use of knowing pregnancy or not, monthly pregnancy states and childbirth. "Haung-di-nei-jing" mentions pregnancy-pulse, for example, "Yin beats and Yang distinguishes", "Shou-shao-yin-mai moves severely", "Lady has some symptoms, but no Xie-mai". Since then, there are many opinions of schools about that. For the period of pregnancy, pulse shows special features, according as the symptoms differ from month to month. When pregnant woman is just about to bear, her pulse changes unusually. In oriental medicine, it is called as Li-jing-mai. Pregnancy-pulse is worth refering to pursue a clinical examination.

  • Pregnancy and puerperium are associated with significant changes in pschological and physiologic health status. Back and pelvic pain is common in pregnancy with prevalence figures in the range of $48\%-90\%$. The pain starts during pregnancy and often disappears soon after childbirth. But the prevalence of such pain four to six months post postpartum is report to be $25-40\%$. In $10-15\%$ of the case the pain become chronics, that is persisting for more than three months after childbirth. Low back pain and pelvic pain maybe caused by several factors related to changes that occur naturally during pregnancy. Changes in the center of gravity can create a strain on weight-bearing structures in bone. Pregnancy related hormones, relaxin, create general laxity of collagenous tissue. Another factor found to be a possible primary or contributing cause for law back and hip symptoms are leg length inequality, weight gain and changes in foot function. This article outlines the physiological and biomechanical changes that occur during pregnancy which have been reported to be possible causes of low back and pelvic pain And then, examination, diagnosis, evaluation and treatment of the woman during pregnancy are described. Standard treatment for low back pain and pelvic pain in pregnancy includes education in anatomy and kinesiology, back-strengthening exercise, training of the abdominal muscles and body posture correction. So, most woman during pregnancy require individual consultation and physiotherapist.

  • Spinal cord stimulation (SCS) is used to manage chronic pain syndromes and it is accepted a cost-effective therapy. Child-bearing women who had SCS become or choose to become pregnant despite these policies pregnancy is a relative contraindication. A 32-year-old woman had SCS as a treatment for the CRPS I of the left lower extremity, During various check up tests, we happen to find out that her serum beta-hCG was positive and confirmed pregnancy. SCS is not recommended in pregnancy because the effects of SCS on pregnancy and nursing mothers had not been confirmed. However, many female patients suffering from chronic pain may expect future pregnancy and we think that they must be informed about the possibility of pregnancy and the effects of SCS device implantation in the course of pregnancy. First of all, a good outcome requires a multidisciplinary team approach, including obstetrics, neonatology, pain medicine and anesthesia, as was used from an early pregnancy. Unfortunately, she had a misabortrion after 6 weeks.

  • The changes of plasma renin activity, aldosterone concentration, serum sodium-, and potassium levels were studied before and after the water loading followed by diuretics injection. The materials were: 13 non-, 11 normal-, and 11 toxemic pregnancy cases. The plasma renin activity and aldosterone concentration of the cord and postpartum blood were also measured. Following were the results: 1. The plasma renin activity was elevated significantly in normal pregnancy, and slightly in toxemic pregnancy. The serum sodium levels were decreased in pregnancy. 2. The plasma aldosterone concentration was slightly decreased in normal pregnancy, and slightly increased in toxemic pregnancy, however, statistically insignificant. 3. The plasma renin activity of the cord and postpartum blood were lower than those of pregnancy cases. 4. The changes of plasma renin activity after the diuretic administration showed an initial increase, which recovered within 2 hours. These changes were the least in normal pregnancy, and the most in toxemic pregnancy. 5. The changes of plasma aldosterone concentration after the diuretic administration were similar to those of plasma renin activity, although the variations were not so wide.

  • This experiment was examined the effect of splenectomy on the hematology in pregnant wistar rat. Only animals that had been shown regular 4-day estrous cycles for more than two cycles were used. The day after mating with the same male animal ws designated Day 0 of pregnancy. Spleen was removed from Day 0(early), 6(middle) and 13(late) of pregnant rat, respectively. Blood sample was collected at Day 1, 7, 14 and 21 of the pregnancy. 1. RBC was increased significantly(P<0.05) to the progress of pregnancy in control rat. The late splenectomized rats were decreased significantly(P<0.05) at Day 21 of pregnancy than control rats. 2. Hb was increased significantly (P<0.05) at 21th day of pregnancy in late splenectomized groups than others group. 3. In the late splenectomized rats, Ht was decreased significant (P<0.05) due to the progress of pregnancy and decreased significantly (P<0.05) at Day 21 of pregnancy in all splenectomized groups. 4. WBC was increased significantly (P<0.05) at Day 1 of pregnancy in splenectomized groups compared with control. 5. In differential leukocyte rate, the Basophils and Monocytes was not significantly changed. Neutrophils was increased significantly(P<0.05) at Day 14 and 21 than Day 1 and 7 of pregnancy in control. Lymphocytes was decreased significantly(P<0.05) in control due to progress of pregnancy. Neutrophils was increased and Lymphocytes was decreased significantly(P<0.05) in splenectomized groups compared with control.

  • This study was carried out to establish an effective system for embryo transfer techniques by analyzing several factors affecting in-vivo embryo transfer in Korean cattle Embryos were transferred into a toral of 301 recipients. The results obtained in studies on the factors affecting pregnancy rate after embryo transfer by condition of transfer time were as follows ; 1. The pregnancy rate by the seasons of transferred fresh and frozen embryos were not different, but the pregnancy rate was slightly higher in summer(80.8%). 2. The pregnancy rate by the days of embryo transfer after estrus were not different when fresh embryos were transferred, but the pregnancy rate was highest at 8 days when frozen embryos were transferred(P<0.01, 40.0%). 3. The pregnancy rate at estrus synchronization was remarkably higher with PGF$_2$$\alpha$ treated than natural (P<0.05, 70.4%, 43.4%). 4. The pragnancy rate by the degree of estrus synchronization was best when the estrus was synchronized in both fresh and frozen embryos (83.3% and 29.7%, respectively), but the pregnancy rate was not different among $\pm$2 days. But the pregnancy rate of frozen embryos were slightly higher when the recipients exhibited estrus earlier than donors.

  • This study was carried out to find the factors which are related to the weight gain during pregnancy of women and infant birth weight. The information of the general characteristics and pregnancy outcomes of the 506 women who had a delivery during Jan to Dec, 1997 in a hospital at Taegu area were collected from the medical records. The results are as follows. The mean age of the subjects was 29 years old and the average prepregnancy weight was 52.75kg. They gained 13.51kg of weight during the pregnancy. The weight gain during pregnancy was higher in prepregnancy BMI<20kg/m$^2$, the infant weight was heavier in groups that had over 14kg of weight gain during the pregnancy than other groups. The prepregnancy BMI was negatively correlated to weight gain during pregnancy(r=0.2825), and positively correlated to number of pregnancy(r=0.2146), number of living delivery(r=0.1409), and infant weight(r=0.1250). The baby weight was Positively correlated to weight gain during pregnancy(r=0.1392) and Apgar score(r=0.1627). The results showed that the prepregnancy BMI and weight gain during pregnancy may be the influential factors on the infant weight, thus we need to develop the specific nutritional management program according to the status of prepregnancy weight.
