1.Transrectal Ultrasonography Guided Vaginal Procedures.
Korean Journal of Obstetrics and Gynecology 1999;42(11):2434-2439
OBJECTIVE: Some vaginal procedures may be safer, easier and more successful if they could be done under direct sonographic vision of the object. METHODS: All the procedures were done under the guidance of transrectal sonography. Suction curettage, after using curved plastic Karman's cannula, additional curettage was done only when there was probable remaining conceptal tissue seen on sonography. If additional curettage was needed curved metal cannula made in the same form as plastic Karman's cannula is used first and then usual metal curette if the former did not work. A high frequency cautery unit was used for myolysis. Insertion of the flexible curved cautery tip into the myoma mass was done through the uterine cavity and coagulation of the myoma tissue was performed. Myoma biopsies were done with thin loop high frequency cautery tip through laparoscopy and the vagina. RESULTS: Suction curettage in 156 cases of early pregnancy and 2 cases of previous cesarean incision site pregnancy, D&C in 11 cases, chorionic villus sampling in 13 cases, polypectomy in 1 case, myolysis in 1 case and myoma biopsy in 2 cases were done. CONCLUSION: Performing some vaginal procedures under the guidance of transrectal sonography may be better.

This study was investigated to compare the staining resistance of soft denture liners. Specimens wee made of Coe-soft. Coe-Comfort, Soft-liner, Visco-gel, and were stored in 1% methyleneblue solution for 24 hours. The amounts of color change before and after treatment with mono-poly and thermocycling were measured by colorimeter(TC-6FX, Tokyo Denshoku Co. Ltd, Japan) for evaluation of staining resistance. The following conclusions were drawn from this study. 1. The staining resistance of Visco-gel was increased, but there was no changer of staining resistance in Coe-soft, Coe-comfort, and Soft-liner after treatment with monopoly. 2. The staining resistance of the Coe-comfort was the least in all soft denture liners. 3. The staining resistance of Visco-gel and Soft-liner were decreased after thermocycling.

Correct discrimination of the first and the second twin is important. Case: (1) The first fetus, whose amnionic cavity was closest to the cervix at 19 weeks, even though its body was higher than the second fetus, was found to be closer to the cervix by 23 gestational weeks than its twin. (2) The result of the chromosomal study of dichorionic twins at 17 gestational weeks was male with 9 inversion of the presumed first, and female with trisomy 21 of the presumed second. AT 19 gestational weeks, the sex and order of the two were found to be reversed at sonography for selective termination. In diamnionic twins, the fetus in the amnionic sac closest to the cervix is nominated as the first.

OBJECTIVE: The aim of this study was to investigate whether embryonic stem (ES) cells can be established from isolated blastomeres of mouse embryos. METHODS: Blastomeres were separated from mouse (C57Bl/6J) 2- or 4-cell embryos. Isolated blastomeres or whole 4-cell embryos were co-cultured with mitosis-arrested STO feeder cells in DMEM supplemented with recombinant murine leukemia inhibitory factor and ES-qualified fetal bovine serum. After the tentative ES cell lines were maintained from isolated blastomeres or whole embryos, some of them were frozen and the others were sub-cultured continually. Characteristics of tentative ES cell lines as were evaluated for specific gene expressions with immunocytochemistry and RT-PCR. RESULTS: One ES cell line (3.0%) was established from isolated blastomere of 2-cell embryo and one cell line (4.0%) from isolated two blastomeres of 4-cell embryo. And five cell lines (16.7%) were established from whole 4-cell embryos. Both cell lines from isolated blastomere and whole embryo expressed mouse ES cells specific markers such as SSEA-1, Oct-4 and alkaline phosphatase. Marker genes of three germ layers were expressed from embryoid bodies of both cell lines. CONCLUSION: This study suggests that mouse ES cells could be established from isolated blastomeres, although the efficiency is lower than whole embryos. This animal model could be applied to establishment of autologous human ES cells from biopsied blastomeres of preimplantation embryos in human IVF-ET program.

A 33-year-old-woman with twin pregnancy underwent genetic amniocentesis in our hospital at 16 weeks of gestation. Fetal chromosomal analysis showed 46,XY,inv(9) and 47,XX,+21. The affected twin was terminated by ultrasonographically guided intracardiac injection of 3 ml potassium chloride solution at 19 weeks of gestation. A healthy 2570 g male infant was born by cesarean section with Apgar scores of 8 and 9 at one and five minutes, respectively.
