This study was carried out to investigate the effects on the mutagenicity and activity of Poncirus trifoliata. Using an Ames mutagenicity test, which has been used to assess both mutagenic and antimutagenic effects of various molecules, it was observed that the water extract of Poncirus trifoliata did not showed any mutagenic activities. but the Poncirus trifoliata water extracts showed inhibitory effects of 43~86% on the mutagenicity induced by indirect mutagen of benzo(a)pyrene (B(a)P) and aflatoxin B1(AFB1) in Salmonella typhimurium TA98. The antimutagenic effect increased with increasing concentration of the water extract toward N-methyl-N`nitro-N-nitrosoguanidine(MNNG) and 4-nitroquinoline-1-oxide (4-NQO).

Twin pregnancies are interesting because of the greater risk to mother and babies than singleton pregnancies. Clinical evaluation with multiple aspects were made on 96 cases of twin pregnancy in Paik Hospital from Jan 1. 1990 to Dec. 31. 1996. The results were as follows: 1. Number of twin pregnancies were 96 cases among 5,321 deliveries. (l:55.4) 2. The predominant age group of gravida was 26 ~ 30 which covers 52.1% of all and mean age was 28.9 years old. According to parity, most frequent group was nullipara which covers 65.3%. 3. The predominent gestational age group of twin births was 35 ~ 36 weeks and mean gestational weeks of twin births was 35(+3). 4. In presentation, the cephalic-cephalic combination was 50% and the cephalic-breech 41.7%. 5. The maternal complications during pregnancy were anemia(55.2%), toxemia(19.8%), and in labor and postpartum state were uterine dysfunction(9.4%), postpartum hemorrhage(21.6%). 6. The most common mode of twin delivery was cesarean section and its incidence was 65.6%. Its main indications were elective, previous cesareansection, malpresentation and preeclampsia. Vaginal delivery was done in 34.4% of the cases, the first baby was 29.2% in spontaneous delivery and 3.1% in vaccum extraction, and the second baby was 18.7% in spontaneous delivery and 11.5% in breech extraction. 7. The average duration of labor was 7.5hours and second baby was delivered within 5 minutes after first baby delivery, in 85.4% of cases. 8. The birth weight of the first and second baby were 2,173 grams and 2,077 grams, respectively and the former washeaiver by 96 grams. 9. In 64.6% of cases, the type of placenta was diamniotic-monochorionic. 10. Both male was 43.8%, both female was 42.7%, and opposite sex was 13.5% in ingant sex. 11. There were 19 perinatal death, its revealing 9.7% of perinatal mortality rate of twin and the most common cause of perinatal death was prematurity with 84.2%. There was one maternal death due to atonic bleeding, and she refused to be transfused because that her religion was Jehovah`s witness.

Embryos of most mammalian species grown in vitro would undergo developmental arrest at the approximate time of genomic activation. Stage-specific cell block and the resulting rapid loss of embryo viability in conventional culture media have limited the duration for which embryos may be cultured prior to transfer. As a result, embryos are usually transferred to the uterus at the 4-to 8-cell stage to avoid the loss of viability associated with long-term in vitro culture. Early transfer has led to asynchrony of the endometrium-trophectoderm interaction at the time of implantation and a resultant reduction in the rate of implantation. To overcome these problems, a variety of co-culture systems has been devised in which embryos can develop for a longer period prior to embryo transfer. Vero cells, derived from African green monkey kidney, share a common embryologic origin with cells from the genital tract. In addition, they are potentially safe to use, since they are highly controlled for viruses and other contaminants. Therefore, co-culture using Vero cells has been widely utilized to enhance embryo viability and development, although not without controversies. We thus designed a series of experiments to demonstrate whether Vero cells do indeed enhance mouse embryo development as well as to compare the efficacy of co-culturing mouse 1-cell embryos on Vero cell monolayer in both Ham's F-10 and human tubal fluid (HTF) culture media. 1-cell stage ICR mouse embryos were cultured either in the presence of Vero cells (Group A) or in conventional culture medium alone (Group B). In Ham's F-10 significantly more 3-to-8cell embryos developed in group A than group B (59.8 versus 10.0%; p<0.01). In contrast, there was no significant difference in embryonic development both group A and group B in HTF. However, significant differences were noted only in later embryonic stage (13 and 0%; p<0.05 of group A and B respectively, hatching or hatched). In Ham's F-10, we also could observe the beneficial effect of Vero cell on hatching process (70.7 and 42.1%; p<0.05 of group A and group B respectively).

주산기 이환율 및 사망율과 밀접한 관계가 있는 있는 지연임신은 산과영역에서 중요한 문제로 취급되지만 아직 이의 원인, 처치 및 태아와 모성에 미치는 위험에 관하여서까지도 의견의 일치를 보지 못하고 많은 논란의 대상이 되어오고 있다. 저자는 지연임신이 신생아 및 산모에 미치는 영향을 비교 검토하여 태아 및 모성관리에 임상적 도움이 되는데 본 연구의 목적을 두고 있다. A clinical observation has been made on 50 cases of postterm pregnancies out of 2,823 cases delivered at the Dept. of Obstetrics & Gynecology, Seoul Paik Hospital from April 1, 1993 to July 30, 1996. A total of 370 among 2,580 cases of full term deliveries of 38 to 42 gestational weeks conducted in same period were used as the control group for this study. The results were as follows : 1.The Incidence of postterm pregnancy was 1.77% with the highest incidence occuring in the 26-30 years of age group. The incidence of postterm pregnancy in primipara(2.74% ) was greater than total of multipara(1.59%). 2.In postterm pregnancies, the gestational weeks of 42 was most prevalent(84%) and 43weeks was the next(14%) . 3.The modes of labor onset in postterm pregnancy showed spontaneous 28.00%, induction 52.70%, and cesarean section without labor 20.00%. 4.The incidence of fetal distress was 3.82% and 10.00% in the control group and postterm group respectively. The incidence of fetal distress in the postterm pregnancy was about 2.62 times greater than that of control group and it increased markedly as the gestational weeks were prolonged. 5.The modes of delivery in postterm pregnancy showed : spontaneous vaginal delivery 52.00% vacuum extracted delivery 6.00% cesarean section 42.00% 6.As the indication of cesarean section in postterm pregnancies, the cephalopelvic disproportion was the most prevalent indication and failed induction, fecal distress, previous cesarean section were the next in order. 7.The incidence of large fetus(weight over 4,000gm) was 10% and 3.24% in the postterm group and control group respectively, and postterm group was about 3.08 times greater than that of control group. 8.The incidence of 1min Apgar score under 7 was 14.00% and 8.11% in the postterm group and control group respectively.
