This study was performed to identify the maternal risk factors for the low birth weight. During the period from February to June in 1991, the medical record review and questionnaire interview were conducted upon the 465 pregnant women who were admitted to and delivered a baby in 3 general hospitals and an obstetric hospital in Kwangju area. The health and other related information from women who bore the low birth weight infant was compared with those from women who bore the normal birth weight infant. The results obtained were as follows : 1. Maternal age, low body weight at term, illegitimate birth, and maintaining work activity during pregnancy were positively associated with low birth weight. 2. The positive association was revealed between low birth weight and the previous abortion, short gestational weeks, anemia, low maternal weight gain during pregnancy, the obstetric present illness and hypertension. 3. Some maternal working conditions were associated with low birth weight although statistically not significant. 4. In multivariate logistic regression analysis, gestational weeks and maternal weight gain during pregnancy were related with low birth weight.

The aim of this study was to report a successful pregnancy using completely immotile frozen-thawed spermatozoa selected by laser. A single laser shot was used to detect the presence of viable immotile spermatozoa in fresh and frozen-thawed testicular spermatozoa. The viability rate was 55.8% after the laser detection, and cryopreservation was carried out immediately. The thawing test was performed on the day of oocyte pick-up, and no motile sperm were observed after extending the culture for another 4 hours, while a survival rate of 39.8% was detected using the laser. In all, five mature oocytes were injected, resulting in four cases of normal fertilization (80%) on day 1. Further, two high-quality day 3 embryos were transferred, which resulted in a singleton pregnancy. Our study demonstrates that completely immotile spermatozoa are worth cryopreserving for further intracytoplasmic sperm injection, which provides a new insight into male fertility preservation in cases of completely immotile spermatozoa.

A 3-year-old Thoroughbred mare was referred to J&C Equine Hospital with gestation day 30 twin pregnancy. On transrectal ultrasonographic examination, two similar sized (28 mm) embryonic vesicles, unilaterally fixed in the uterine horn, were detected. Transvaginal ultrasound-guided aspiration (TUGA) was performed for reduction of one embryonic vesicle. Yolk sac and allantoic cavity fluids from one embryonic vesicle were aspirated by a needle guided by using transvaginal ultrasound. The mare continued normal singleton pregnancy after twin reduction and delivered a foal successfully. This is the first case described the clinical use of TUGA in Korea. Clinical use of TUGA in twin reduction after embryonic fixation is recommended for equine clinicians.

Uterine cells carry out proliferation and differentiation for preparation the embryonic implantation during pregnancy. Therefore regulation of the cell proliferation is an essential step for uterine preparation, but there is not much information about the proliferation related genes in pregnant uterus. To identify these implantation specific genes, a PCR-select cDNA subtraction method was employed and got a few genes. One of the identified genes is a novel gene encoding oral tumor suppressor doc-1. To detect the doc-1 expression on the pregnant uterus, dot blotting, RT-PCR, and in situ hybridization were employed. Dot blotting revealed that doc-1 mRNA expression increase after implantation. During normal pregnancy, doc-1 mRNA expression was detected as early as day 1 of pregnancy with RT-PCR. Its expression was increased about 15 times after embryonic implantation. doc-1 transcript was localized in luminal epithelial cells but it was very faint during preimplantation. After starting the implantation, it localized in the stromal cells; heightened expression of doc-1 correlates with intense stromal cell proliferation surrounding the implanting blastocyst on day 6 morning. However in the decidualized cells, the intensity of localized doc-1 mRNA was weak. From those results, it is revealed that doc-1 express at pregnant uterus of the mouse. In addition it is suggested that doc-1 is the gene regulating the proliferation of the luminal epithelial cells and stromal cells during early implantation and decidualization.

Salpingoscopy may be helpful in the diagnosis of subclinical epithelial, vascular damage and stricture formation, which may playa significant role in infertility, or predispose women to tubal pregnancy, despite of clear demonstration of tubal patency on hysterosalpingogram. We explored the fallopian tube from the fimbriae to the ampullary-isthmic junction with small rigid flexible endoscope during laparoscopy in sixteen patients from July 1991 to Jan. 1992. All patients have been observed following salpingoscopy for several months. Three pregnancies were achieved in seven patients with bilaterally normal or minimally damaged tubal mucosa. In another five patients with moderate to severe tubal damage, we noted one tubal pregnancy. The other remaining patients are being followed up now. As conclusions, salpingoscopy seems to be an useful tool in the diagnosis of tubal lesions which are not identified by H.S.G., give much help to refine the indications for tubal microsurgery and the selection of patients for GIFT or IVF-ET and to determine the prognostic value in terms of risk for ectopic pregnancy.

Partial hydatidiform mole and coexisting fetus is a rare entity with antecedent high risk of maternal and fetal complications, and risk of persistent trophoblastic disease in later life. Here, we report a case of twin pregnancy with live fetus identified as 45,X and normal placenta and another partial mole. Ultrasound scan at 10 weeks showed a hydrops fetus with a focal area of multicystic placenta. The patient underwent chorionic villus sampling and amniocentesis for chromosomal analysis, and the result was 45,X. Based on these finding, the patient then underwent induced abortion. Pathological examination (immunohistochemical staining) of the placenta confirmed the partial mole. This report suggests that careful prenatal ultrasonography and appropriate karyotyping in a molar pregnancy and coexisting fetus enable early diagnosis and may be beneficial for prognosis.

A twenty three year old, Primigravida and 32 week pregnant woman who has been complained dyspnea, chest pain, nausea and vomiting was admitted to this chest surgical department on Feb. 19, 1979. Physical findings were those of acutely ill appearance, decreased thoracic excursion and absence of breath sounds in the left hemithorax. Roentgen examination of the chest revealed reticular cystic densities in the left, particularly in lower lung field with collapse of the left lung. Correction of the diaphragmatic hernia was carried out with reduction and repair of the hernia through transperitoneal approach. On exploration, the defect of the diaphragm was 12 x 12 cm in size and was located posterolateral area of left diaphragm. Hernia contents were stomach, spleen, omentum and splenic flexure of large bowel. The baby was normal full term spontaneous delivered at 36th POD. Diaphragmatic hernia complicated by pregnancy is a rarity and mortality is extremely high. Therefore, the literatures have reviewed and the case is reported.

Idiopathic peripartum cardiomyopathy is an uncommon malady disease. Making the diagnosis is often difficult and it is always necessary to exclude other prior heart disease and other causes of left ventricular dysfunction in pregnant women. Heart failure in these women ensues when the cardiovascular demands of normal pregnancy are further amplified when the common complications of pregnancy complications superimposed upon these underlying conditions that cause compensated ventricular hypertrophy. This may be aggravated by making a late diagnosis and providing inappropriate treatment. We experienced a 38-year-primigravida who has diagnosed with idiopathic peripartum cardiomyopathy and underwent elective cesarean section with general anesthesia.
