We report a case of prenatal diagnosis of fetal congenital goiter at 31weeks of gestation by ultrasonogram and fetal hypothyroidism confirmed at birth as thyroid function test by umbilical cord blood sampling. Maternal Graves' disease and the drugs used to treat hyperthyroidism in pregnant women can affect the fetus, causing hyperthyroidism or hypothyroidism and goiter. Fetal hypothyroidism may be caused by transplacental passage of either maternal thyrotropic-binding inhibitory immunoglobulin(TBII) antibodies or maternal treatment with propylthiouracil(PTU). Untreated fetal hypothyroidism may result in mental retardation, perceptual-motor, visual-spatial, and language developmental problems. In this article fetal thyroid function was not assessed by cordocentesis, but fetal congenital goiter was detected ultrasound. Ultrasound should be used to detect fetal goiter from 20 weeks onward. Fetal goiter should resolve when maternal PTU treatment is decreased. We have diagnosed fetal hypothyroidism in utero by ultrasonography. Significance of in utero management of fetal hypothyroidism is discussed.

This study was undertaken for the clinical analysis and evaluation on 121 patients with incompetent internal os of the cervix, who were admitted and treated with McDonald operation or Shirodkar operation at the Soonchounhyang Medical Center from January 1991 to December 1995. The results of this study were as follows : 1. The incidence of this IIOC was 1.1% of 11,116 cases of total delivery. 2. The mean age of IIOC was 31.7 years old. 3. The average number of gravida was 3.2. 4. The most common contributary factor was previous history of artificial abortion (51.2 %), and midtrimester abortion (17.4 %), cervical laceration due to previous vaginal delivery (8.3 %) etc. was followed. 5. The success rate of operation was 76 %, and the highest success rate (85.7 %) was reveald with period from 15th weeks to 16th weeks of gestation. 6. When cervical dilatation was abscent or small, the success rate of operation was high. 7. The factors of failed operation were preterm labor (58.7 %), PROM (34.5 %), and PIH, bleeding. 8. The delivery method after operation was vaginal delivery in 83 cases (68.6%) and cesarean section in 38 cases (31.4 %).

OBJECTIVEA quantitative method was developed for the determination of tenuifolin in Tianwang Buxinwan and Guipiwan by HPLC.

METHODThe samples were separated by Alltima C18 column (4.6 mm x 250 mm, 5 microm) using methanol--0.05% phosphoric acid (65:35) as a mobile phase, flow rate was 1.0 mL x min(-1) and wavelength was set at 202 nm.

RESULTTenuifolin was detected in both Chinese preparations. The number of theoretical plates calculated by tenuifolin peak was 2 500. The regression equation of tenuifolin was Y = 5.239 x 10(6) X-6.247 x 10(5) (r = 0.9994) and the liner range was 10-500 g x mL(-1). The average recovery of tenuifolin was 97.5% (RSD less than 3.0%). The LOD of tenuifolin was 5.50 g x mL(-1).

CONCLUSIONThe method is sensitive, rapid and accurate.

The purpose of our experiment is to examine the level of anti-Haemophilus influenza polysaccharide antibody titer in the Korean population. Using ELISA, the level of Hib-PS antibodies in 384 infants and children who were all free from Hib invasive diseases, was tested. And the blood of 50 mothers within 24 hours of delivery and cord blood from their respective full-term neonates was also tested. The transport of Hib-PS IgG and IgG subclasses in paired sera from mothers and neonates was also measured. The titer of Hib-PS IgG varies with age. At birth the mean optical density of cord blood was 1.028; however, it declined to 0.609 up to 6 months and further decline was noted up to 2 years to 0.488. Then the mean O.D. remained around 0.5 from 3 to 14 years of age. The mean O.D. of Hib-PS IgG in the mothers blood was 0.856. The ratio of mean O.D. of anti-Hib PS IgG antibody in the cord blood to that in the maternal blood was 1.20. The mean optical densities of IgG subclasses were: 1.18 for anti-Hib PS IgG1, 1.07 for anti-Hib PS IgG2, 1.01 for anti-Hib PS IgG3, and 1.09 for anti-Hib PS IgG4. The sera from Korean children of almost all age groups reacted to Hib-PS antigen on ELISA. Also the active transport of anti-Hib PS IgG antibody through placenta was observed. Among four IgG subclasses, only IgG1 transport had significant experimental meaning.
