Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with florisil, and finally analyzed simultaneously the organochlorine and pyrethroid pesticides using GC(ECD). An ultra-2 fused silica capillary column was used to separate and identify the products. The resolution between the last isomeric peak of cypermethrin(59.987min) and the first isomeric peak of flucythrinate(60.043min) was not satisfactory. The last isomeric peak of fenvalerate(62.344min) and the first isomeric peak of fluvalinate(62.397min) were overlapped. Recoveries of soybean sample for the most pesticides were 73.3% to 102.4%. Detection limits were between 0.004 and 0.063 ㎍/㎎ when this method was used.

Background : In recent years gonorrhoea has been panendemic and remains one of the most common Sexually Transmitted Diseases in the world, especially in developing countries. Objective & Method : For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria Gonorrhoeae(PPNG), Ive have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1994, 168 strains of N. gonorrhoeae were isolated, among which 109 (64,9% ) were PPNG. Conclustion : Our results suggests that the prevalence of PPNG in Seoul is still increasing.

There are many placental oncofetal antigens or enzymes clinically used in the diagnosis of gynecological cancers. The placental alkaline phosphatase(PAP), one of placental enzyme, is membrane bounded glycoprotein occurring in trophoblasts 12 weeks after gestation. PAP is differentiated from the intestinal or skeletal alkaline phosphatase by its heat stability, electrophoretic migration and other immunologic methods. Recently PAP is reported to be present in the sera of the patients suffering from tumor of the female genital tract, lung, testis or breast. The author had performed immunohistochemical staining using anti PAP sera to determine the presence of PAP in the normal and tumorous gynecologic tissue. The results are followings. 1. Normal cervical mucosa revealed negative reaction except superficial layer of exocervical squamous cells. And cervical tumors were all negative. 2. Normal and neoplastic lesions of endometirum showed negative reaction. But endometrial hyperplasia revealed positive reaction in more than 70% of the hyperplastic glands. 3. All normal ovarian tissue components revealed negative reaction to anti PAP but clear cell carcinoma, teratocarcinoma and dysgerminoma were tumors showing positive reaction to anti PAP among ovarian tumors.

The treatment of complete avulsed teeth due to traumatic injuries is replantation procedure. The major complication of replantation are pulp necrosis, ankylosis, and root resorption. It is important to maintain the vitality of periodontal ligament to minimize the complications. The purpose of this case report is to consider the facts that affect the success rate and the prognosis of complete avulsed teeth replantation. All of these cases had different conditions and transport media. The followng results were observed : 1. The successive treatment of complete avulsed teeth requires the maintainance of vitality of periodontal ligament. 2. The complication of replantation are inflammatory root resorption and ankylosis and in such case, proper endodontic treatment using calcium hydroxide medications and periodic observations are needed. 3. In case of delayed replantation, the use of fluoride and root planning procedure can help to achieve better result. 4. It is more esthetic and functional to maintain the avulsed tooth in mouth.

The purpose of this study is to determine the ageing mechanism of Mica/Epoxy composite material for large generator stator windings in order to estimate remaining life of generator. X-ray analysis is performed to investigate the position and structure of mica crystal in insulation materials. The phase change of aged and sound specimen under each atmosphere isn't observed. Surface analysis of insulation materials by optical microscope also show that the sound and aged specimen, sliding phenomenon by shear and thermal stress is observed both interface between mica and epoxy.

This study was carried out in order to investigate the processing adaptability of Jeung-pyun. We used rice materals that were developed domestically for improving the utilization of rice. Six cultivars(Ilpoombyeo, Hwasungbyeo, Dasanbyeo, Daeribbyeo 1, Hyangmibyeo 1, Hyangmibyeo 2) of rice were used for making Jeung-pyun. In physicochemical properties of rice, Hwasungbyeo had the highest amylose content(20.4%) and Hyangmibyeo 2 had the lowest one(14.9%). Lipid content was 0.23%(Daeribbyeo 1)~0.43%(Ilpoombyeo), protein content was 7.94%(Ilpoombyeo)~8.43%(Dasanbyeo), and ash content was 0.15%(Hyangmibyeo 2)~1.24%(Daeribbyeo 1). In volume and specific volume of the 3 hour fermented Jeung-pyuns, Ilpoombyeo, Hwasungbyeo, Hyangmibyeo 2 were higher, but in the 7 hour fermented Jeung-pyuns, Dasanbyeo, Daeribbyeo 1, Hyangmibyeo 1 were higher. In the sensory evaluation of the test Jeung-pyuns, the overall quality of the 3 hour fermented Jeung-pyuns was not significantly different among the rice cultivars, whereas in the 7 hour fermented Jeung-pyuns Hyangmibyeo 2 had the lowest values. When the 7 hour fermented Jeung-pyuns were stored at 20℃, the hardness and brittleness of Jeung-pyuns were respectively increased, the cohesiveness was respectively decreased. The elasticity was not significantly different among the rice cultivars with storage days, and the gumminess was significantly difference between rice cultivars, respectively increasing during storage, but Hyangmibyeo 2 was the lowest, not increased. In instrumental characteristics of Jeung-pyuns, the hardness was correlated with amylose content and the brittleness and gumminess were highly correlated with the hardness.

목적 : 아단위 인플루엔자 백신 접종 후 백신의 인플루엔자 예방효과, 인플루엔자 방어 항체형성, 인플루엔자 백신의 안전성을 조사하고자 하였다. 방법 : 총 571명을 대상으로 인플루엔자 백신 접종을 하였고, 이들 접종자에서 인플루엔자 양질환의 이환을 조사하여 인플루엔자 백신의 인플루엔자예방효과를 알아보았고, 백신의 접종 전 및 접종 4주 후 혈청에서 혈구응집억제물(Hemagglutination Inhibition : HAI) 항체 검사를 실시하여 백신의 방어항체생성을 조사하였고, 백신의 안전성을 알아보기 위해 백신접종 후 1주일 이내의 부작용을 조사하였다. 결과 :백신 접종군과 백신 비접종군에서 인플루엔자 양 질환의 이환을 조사한 결과 접종군 28.35%, 비접종군 35.88%으로 나왔으며, p 값이 0.001로 통계적으로 접종군에서 유의하게 낮았고, 인플루엔자 양 질환의 예방 효과는 20.97%를 보였다. 백신의 방어항체 형성의 평가를 위해 유럽의 인플루엔자 백신 허가 기준을 조사하였는데 B/Guangdong/5/94균주의 백신접종 후 항체가 40이상의 비율을 제외한 다른 기준은 모두 만족 시켰다. 부작용은 전체 조사자 521명중 149명(29%)으로 주로 접종 부위의 국소 부작용을 호소했고, 전신 부작용은 2% 내외였으며 특별히 심각한 부작용은 발견되지 않았다. 결론 : 분편 인플루엔자 백신은 인플루엔자양질환의 예방과 방어항체생성에 효과 있으며 안전한 것으로 사료된다. Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain. And the adverse effects were mainly local injection site problem and no serious adverse effect was noted. Conclusion : Split influenza vaccine is safe, inmunogenic and eff'tive in influenza risk group in Korea.
