OBJECTIVE: We performed the transvaginal ultrasonographic evaluation of uterine cervix and fetal fibronectin in cervicovaginal secretions in women after 37 complete weeks of gestation to predict the onset of labor. METHODS: Total 80 primiparous or multiparous women were divided into two groups on the duration between evaluation and onset of labor. The biometric analysis of uterine cervix(cervical index, endocervical length, funneling, funnel length and width) was done by transvaginal ultrasonography. The cervicovaginal fetal fibronectin was measured by fetal fibronectin immunoassay (ELISA kit, Adeza Biochemical, USA). The efficacy of these method was analyzed with Pearson chi-square test, receiver-operator characteristic curves, and multiple logistic regression test. RESULTS: 1) There were no significant differences in clinical characteristics between two groups. 2) Group 1(onset of labor within 7 days after evaluation) showed significantly shorter endocervical length(Group 1: 2.33+/-0.75cm,Group 2: 2.93+/- 0.42cm, p=0.013), higher value of cervical index(Group 1: 1.27+/-0.67, Group 2: 0.62+/-0.34, p=0.008) and higher level of fetal fibronectin(Group 1: 98.65+/-11.34ng/ml, Group 2: 13.37+/- 2.7ng/ml, p=0.004). 3) The ROC curve analysis showed that a level of endocervical length <2.64mm, cervical index> 0.7, fetal fibronectin> 60ng/ml had the diagnostic performance in predicting group 1. Fetal fibronectin level in cervicovaginal secretion> 60ng/ml showed the highest diagnostic index in predicting the onset of labor within 7 days(p<0,001, odds ratio=21.3). CONCLUSION: Cervicovaginal fetal fibronectin predicts delivery within 7 days more accurately than cervical index, endocervical length. Combine use of these tests improve the diagnostic efficiency and allowed prediction of onset of labor, identifying a subgroup of patients who may require aggressive treatment.

OBJECTIVE: To compare the efficiency, success rate and abortion time between the live and the dead fetus in second trimester pregnancy termination with intravag-inal misoprostol. SUBJECTS AND METHODS: A total of 45 pregnant women between 18-29 weeks of gestation with medical, obstetric, or genetic reasons for termination were recruited to receive 50 ug misoprostol inserted intravaginally (posterior fornix) every 4 hours. RESULTS: The success rate of complete termination(abortion) within 12 and 24 hours in dead fetuses were 78.2% and 95.6%, respectively, while in live fetuses were 36.3% and 90.9%, respectively. The mean abortion time of the dead fetus group (10.31+/-3.43 hours) was significantly less than that of the live fetus group (14.20+/-3.31 hours). No serious complications occurred in terms of hemorrhage, diarrhea, nausea and vomiting. CONELUSION: Intracervicovaginal misoprostol is a safe and effective method for second trimester pregnancy termination. The abortion time is less in dead fetus pregnancy than that in the live fetus pregnancy.We used 50 ug tablets of misoprastol every four hours. But, we suspect that the regimen of 100ug misoprostol inserted intracervicovaginally every eight hours will beis the proper and optimal method for pregnancy termination.

To evaluate the relationship between p53 protein expression and proliferating activity in astrocytic tumors, we performed a study using 37 cases of astrocytic tumors; 13 cases of low-grade astrocytoma (LGA), 9 cases of anaplastic astrocytoma (ANA), and 15 cases of glioblastoma multiforme (GM). The p53 protein expression was studied by immunohistochemical staining (IHC) with DO-7 monoclonal antibody in 37 cases and p53 mutation was detected by single strand conformational polymorphism (SSCP) using PCR products of 31 cases. Proliferating activities were detected by Ki-67 (MIB-1) and proliferating cell nuclear antigen (PCNA). Immunohistochemically, 24.3% (9/37) of astrocytic neoplasms showed p53 expression, which consisted of 7.7% (1/13) of LGA, 44.4% (4/9) of ANA, and 26.7% (4/15) of GM. The p53 expression was statistically significant between the tumor grades. p53 mutations on exon 5 were noted in 6 (19.4%) out of 31 cases of astrocytic tumors. Average indices of MIB-1 and PCNA were 1.5 2.6% and 7.0 10.1% in LGA, 10.0 12.7% and 23.7 23.2% in ANA, and 30.9 22.4% and 69.9 26.7% in GM, respectively. p53 positive group by IHC showed significantly higher average MIB-1 (26.2 23.5%) and PCNA index (56.7 30.3%) than those (12.1 18.3%, 27.6 29.6%) of p53 negative group (p<0.05). p53 mutation group also showed significantly higher MIB-1 (30.7 26.0%) and PCNA index (55.5 32.6%) than those without p53 mutation (10.8 16.5%, 24.2 28.7% respectively). These results showed that about one-fifth of astrocytic tumors have p53 abnormalities, which were related with higher proliferating activities than those without p53 abnormalities.

BACKGROUND: The morphalogy of fibroblast in culture is important in the discrimination of normal and abnormal cells as well as in recogniring general physiologic status of the cells. There have been many reports on the morphologic clialges in various skin diseases and in response to various drugs. However, we couldnt find any report on the time-sequential morphologic changes of normal fibroblasts in early subculture using light microscopy. OBJECTIVE: The purpose of this study is to describe the time-sequential morphologic changes of normal fibroblhst in early subculture. METHODS: The fibroblaats from 4 normal donors were cultured. We observed the morphologic changes of fibrolMasts in the third passage of subculture using light microscopy at 0-, 30-, 60-, 90-, 120-minutes, 3-, 5-, 24-, 72-hours and days after trypsinization, and electron microscopic exarriioation was done at 21 day-culture. RESULTS & CONCLUSION: Just after trypsinization, the cell were small and round, which divided and increased in number as time went by. At 120-minute culture, many cells had long and thin cytoplasmic elongations and they took stellae,shape at 5-hour culture. At 24-hour culture, several spindle-shaped cells were observec with cell-cell contacts. At 72-hour culture, many spindlle-shaped cells were arranged in medirection, with the appearance of parallel or whorl patterns and showed prominent cell-cell contacts. On electron microscopic examination, there were prominent RER, residial bodies and microfilaments.
