Morphological features of the interaction between the hatching blastocyst and implantation in pig were studied by electron microscopy. The observations extended from late blastocyst stage to the completion of trophoblastic erosion of the epithelium and early decidual transformation of the epithelium and early decidual transformation of the stromal cells. Between day 7 and 17 of pregnancy, blastocysts from 0.3 to 12 mm in diameter were flushed from the uterine horns of Dutch Landrace pigs. On the 7th of development in the pig blastocyst, the blastocyst shedded of the zona pellucida established the tips of microvilli and with bleb-like cytoplasmic protrusions of the epithelial cells. From day 11 on in pig embryo, the bilayered trophoblast undergoes a dramatic phase of elongation so that the initially spherical expanded blastocyst becomes tubular. In pig, close apposition to the uterine wall beg-ins at about 12 $^1$/$_2$ days and then attachment occurred during the afternoon of the 16th or 18th day post coitum. At this stage, embryonic loss compared with corpus luteum number is up to 40% of ovulated oocytes. Therefore, the implantation failture of these embryos may be mainly caused by morphological abnormality and failture of zona shedding.

This study was performed to investigate the correlations between steroids and TGF-${\beta}_1$ levels and delayed parturition in SCNT clone calving. The recipients pregnant by AI were used as control (AI-R). All AI-R were labored by natural delivery (n=5, day $284{\pm}0.71$ of pregnancy). The recipients pregnant by SCNT embryo (SCNT-R) showing no signs of delivery about 10 days after expected date were operated by Caesarean section (n=5, day 292). The blood and placentome samples were obtained and weighed at parturition. The concentrations of plasma progesterone (P4) and Estradiol-$17{\beta}$ (E2) were measured by radioimmunoassay (RIA). The levels of plasma and placental TGF-${\beta}_1$ levels were examined by ELISA. The placentomes from SCNT-R were overweight (p<0.05) compared to those of AI-R. The plasma P4 (p<0.01) level in SCNT-R at parturition was significantly higher compared to that of AI-R. In contrast, the plasma E2 level in the SCNT-R was significantly lower compared to that of AI-R (p<0.05). The plasma and placental TGF-${\beta}_1$ protein levels in the SCNT-R were significantly higher than those of AI-R at parturition, respectively (p<0.01). Based on these results, aberrant expressions of steroid hormones and high levels of plasma and placental TGF-${\beta}_1$ protein at parturition may be one of the key indicators on delayed parturition of SCNT clone calving.

To test the validity of referral of high risk pregnancy in the MCH Center, 6,017 pregnant women who visited MCH Center of South District Health Center for delivery between 1 April 1985 and 31 March 1987 were interviewed on arrival to obtain the data for demographic characteristics and obsteric history and traced to check the delivery outcome. Out of 5,820 women whose delivery outcomes were confrmed, 704 women(12.1%) were referred to other hospital or clinic for high risk factors. The proportion of poor delivery outcome(stillbirth, low birth weight and neonatal death) among referred cases was 4.4% while that of the women delivered at the MCH Center was 2.2% (p<0.01). Decision of the midwives for the referral of high risk pregnancy based on their clinical assessment was consistent with the delivery outcome (good or poor) in 86.5%. Major reasons for referral were premature rupture of membrane(46.5%) and cephalopelvic disproportion(20.0%) and the C-section rates for these cases were 10.1%, 17.6%, respectively. Discriminant analysis of the demographic characteristics and obstertric history for the discrimination of delivery outcome showed that gestational age had the highest discriminant function coefficient(0.88) and it was followed by parity(0.37) and maternal education(0.30). Referral of high risk pregnancy by the midwives based on their clinical assessment was considered to be reasonably valid. However, a risk scoring system for an MCH Center which can improve the validity may be developed if one applies the discriminant analysis for more comprehensive independent variable(including clinical assessment of midwife, demographic characteristics and obstetric history) and dependent variable (including medically indicated C-section, complication of pregnancy and delivery, stillbirth, low birth weight, neonatal death and maternal death).

The Codonopsis pilosula is traditional oriental herb associated with immune-modulatory functions and has anti-inflammatory properties and antioxidative activity. The present study was conducted to investigate the effects of dietary supplementation of Codonopsis pilosula extract powder (CEP) on the immunity and productivity in sows and piglets. A total of 20 pregnant sows were randomly assigned to two dietary treatments, which was given a corn-soybean meal diet with 0% and 0.5% CEP from 40 days prepartum to weaning (25 days postpartum). The immune system of piglets was expected to build up, because the feeding of CEP might increase the colostrum contents in sows. We also predicted that the growth performance of piglets also could be increased by some compensation effects due to the increased immunity of piglets. In results, immunities of sows and piglets as well as growth performance of piglets were not affected by the supplementation of CEP. The correlation between the colostrum and the serum on the IgG contents tended to have a positive correlation, although there was no significant (coefficient, 0.435; P=0.102). This result suggests that the supplementation of CEP may increase IgG contents in sows and piglets and contribute to improve immunity of piglets. In conclusion, it is thought that the physiologically active substances of CEP did not influence to the immune synergic effects in vivo of sows. Thus, the metabolic and action mechanism of the physiologically active substances of CEP should be explored to evaluate the availability of CEP as a feed additive for the immunomodulator.

Background : Iron deficiency anemia(IDA) is a very common condition, and its underlying causes are diverse. Gastrointestinal blood loss, pregnancy, menorrhagia are known as common causes of IDA. However, especially in the IDA case of unknown origin, we must consider the culture specific cause of IDA as a possible cause of IDA. As I found an unusual cause of IDA related to a cultural behavior, I would like to report two cases of IDA occurred by negative therapy in Korea. It is possible to explain these cases by explanatory model. Case 1 : With a chief complaint of dyspnea, a 27-year-old woman visited our clinic. She had multiple treatment histories of negative therapy for her psoriasis. The blood loss during this procedure is the cause of present IDA. Case 2 : A 70-year-old man visited our clinic complaining of anorexia and dizziness. The history of treatment showed that he had an IDA 9 month ago. The IDA developed again because of repeated negative therapy after previous treatment of IDA. He has used the negative therapy intermittently to treat tinea pedis for 5 years. Conclusion : We must consider the negative therapy as a possible cause of IDA in Korea.

This study was performed for the purpose of providing basic data of the pelvic disorders through survey of the frequency of management of occurrence by major risk factor. Female pelvic mass was detected using sonography, and necessary data were collected from 604 female visitors to a obstetrics and gynecology hospital located at S-si. Female pelvic mass was uterus mass, ovarian mass, cervical cyst, endometrial disease. For the analysis, such variables as age, weight and frequency of pregnancy were chosen as risk factors. Results of the analysis and conclusions are as follows ; 1) The frequency of occurrence of the female pelvic mass is highest, as 38.9% of the component ratio, in the age of 35 to 54. It maintains high level of 35.8% even in the age of 55 and above. 2) The frequency of occurrence of the female pelvic mass increases in proportion as the weight and frequency of pregnancy increase. 3) The size of the uterus tumor has no statistical relationship with the risk factors, age, weight and frequency of pregnancy.

Preimplantation genetic diagnosis (PGD) has become an assisted reproductive technique for couples who are at risk that enables them to have unaffected baby without facing the risk of pregnancy termination after invasive prenatal diagnosis. The molecular biology and technology for single-cell genetics has reached an extremely high level of accuracy, and has enabled the possibility of performing multiple diagnoses on one cell using whole genome amplification. These technological advances have contributed to the avoidance of misdiagnosis in PGD for single gene disorders. Polymerase chain reaction (PCR)-based PGD will lead to a significant increase in the number of disorders diagnosed and will find more widespread use, benefiting many more couples who are at risk of transmitting an inherited disease to their baby. In this review, we will focus on the molecular biological techniques that are currently in use in the most advanced centers for PGD for single gene disorders, including biopsy procedure, multiplex PCR and post-PCR diagnostic methods, and multiple displacement amplification (MDA) and the problems in the single cell genetic analysis.
