Background Development of genetically modified crops has rapidly increased in last few years. The most widely grown GM crops express genes that confer herbicide tolerance and insect resistance. Detection system of GM crops is important for safety evaluation before its consumption. Objective The purpose of this research is to detect GM crops, especially PAT, in food-samples. Results The bar gene (PAT protein, herbicide resistant) was cloned in pGEX-4T-1 and expressed by E. coli. The high-affinity PAT-specific single-stranded DNA (ssDNA) aptamers were obtained from a random DNA library. MOE docking study was performed to identify the potential binding region of the selected aptamers on PAT. Aptamer-linked immobilized sorbent assay (ALISA) method was used to detect PAT. Conclusion We screened aptamer against PAT for developing an efficient detection method. The selected PAT specific aptamers, HRPA-05 and HRPA-07, showed the distinct target binding behaviors, and detected PAT protein by aptamer-linked immobilized sorbent assay method with high efficiency and selectivity.

The aim of this study was to examine the acoustic characteristics of the monophthongs in the Jeonnam-Jindo dialect. For this purpose, the experiment was conducted and data was gathered from Jindo dialect speakers in their 10s and 5,60s. The data were analyzed on the basis of the subjects’ generation, gender. The result of production experiment was that Jindo dialect speakers have same vowel system between generations: 7 vowel system (/i, E, a, □, i, u, o/). The older generation of Jindo speakers mostly pronounce /ㅚ/ and /ㅟ/ as monophthong irrespective of sex and the young generation of Jindo speakers entirely pronounce /ㅚ/ and /ㅟ/ as monophthong. Also, we found that /Щ/, /u/ moved toward front and /o/ moved toward high in the vowel space from the Jindo speakers in their older to those in their young. And /Λ/ showed a shift in the vowel space from the back to the open vowel. The results revealed a chain-like shift in the high and mid back vowels. It is assumable that the degree of standardization appearing in the place of articulation on vowel is quite high in the Jindo dialect. Previous studies discussed the Jindo vowel system on the basis of the observations made by the researchers. The current study, on the other hand, is significant in that it investigated sound changes in vowel production throughout the vowel system and confirmed the articulation place of vowel using phonetic methods.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Optic neuritis presents differently in children than in adults. Children typically have bilateral involvement with papillitis following an antecedent viral illness. The development of multiple sclerosis is less common in children. The diagnosis of optic neuritis is usually made on a clinical manifestations. The major symptoms of optic neuritis include one or more of the following: 1) sudden blurred, "foggy" vision and sudden loss of vision, 2) pain with eye movement in the affected eye, 3) sudden color blindness, and etc. This condition progresses over a few days to two weeks. A 12-year-old girl presented with a history of sudden visual loss and color blindness. Treatment with high doses of steroid resulted in visual function returning to normal.

연구목적: 이성대상포진에 동반되는 안면신경마비는 Bell's palsy와는 달리 예후가 더 나쁘고 그 마비가 완전히 회복되지 않는 경우가 더 많다.본 연구에서는 이성대상포진에서 발현되는 증상들의 유무가 치료 전 안면신경마비의 정도 및 치료 후 예후와 상관관계가 있는지를 관찰하여 예후의 예측인자에 대해 분석하였다. 재료 및 방법: 지난 1992년 1월부터 1999년 6월까지 이성대상포진으로 진단받고 본원에 입원하여 고용량 부신피질호르몬제와 항바이러스제인 acyclovir의 병합투여로 동일한 치료를 받은 30명의 환자를 대상으로 후향적으로 의무기록을 분석 및 고찰하였으며, 치료 전 안면마비의 정도와 치료 후 마비의 회복 정도를 이통, 이명, 난청, 현훈 등의 증상의 유무와 치료 시작 시기, 그리고 안면신경의 electroneuronography(ENoG) 값에 따라 비교하였다. 결과: 이성대상포진수포가 안면신경마비 보다 먼저 발현된 경우에 안면신경마비의 치료 전 grade가 통계적으로 유의하게 좋았다(p<0.05).이통, 청력손실, 그리고 현훈의 유무에 따른 안면신경마비의 정도는 상관관계가 없었고 예후에도 차이가 없었다.이명의 유무에 따른 치료 전 안면신경마비의 정도는 상관관계가 없었으나 치료 후 완전회복율은 이명이 있었던 군에서 통계적으로 유의하게 높았다(p=0.003<0.05).완전회복군과 불완전회복군 사이의 치료 전 ENoG의 수치는 통계적으로 유의하게 예후와 상관이 있었다(p=0.037<0.05). 결론: 좀더 많은 수의 환자를 연구에 포함하여 증상에 따른 예후의 차이를 연구하는 것이 필 요하며 또한 ENoG 값이 10%에서 40% 사이인 환자들의 치료 방법에 대한 고려와 이성대상포진수포가 안면신경마비보다 먼저 생긴 환자에서 치료 전 마비정도가 경미했던 이유에 대한 연구가 필요할 것으로 생각된다. Purpose: Herpes zoster oticus generally has a poor prognosis, leaving many patients with permanent facial nerve dysfunction, compare to Bell's palsy.Acyclovir and prednisolone have been widely used for the treatment of herpes zoster oticus.This retrospective study was conducted to suggest the prognostic factors according to various symptoms. Materials and Methods : Clinical studies were retrospectively performed on 30 patients with herpes zoster oticus who were treated with acyclovir and prednisolone in the Chungbuk National University Hospital between 1991 and 1999.The authors analyze the pre-treatment grade and prognosis of facial nerve palsy according to symptoms(the existence of otalgia, tinnitus, hearing loss, and vertigo), the treatment onset, and electroneuronography ( ENoG ). Results : Of thirty patients who have been diagnosed as herpes zoster oticus, there is no significant difference in the pre-treatment grade of facial nerve palsy according to the existence of vesicle, otalgia, tinnitus, vertigo, and hearing loss.Of 25 patients who have facial nerve palsy, the recovery from the palsy is complete in 14 patients(56%).There is no significant difference in the pre-treatment grade of facial nerve palsy according to the existence of otalgia, tinnitus, vertigo, and hearing loss.The pre-treatment grade of facial palsy is better when the vesicles precede facial in the group with tinnitus than without tinnitus.A significant difference of the prognosis according to the onset of treatment and other symptoms are not found.ENoG is better in the group that facial nerve palsy is completely recovered than incomplete recovery group. Conclusion : Reliable prognostic factor according to symptoms is not found, ENoG is the only prognostic factor.

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.

결정화 공정을 위한 L-ornithine aspartate의 용해도에 관한 연구

신동명,김용욱,김우식 慶熙大學校 1998 論文集 Vol.27 No.-

Study on the solubility of L-ornithine aspartate with temperature, alcohol, additive was invescated. Generally, the solubilities of amio acids are effected by orniganic solvent, so the solubility of L-ornithine aspartate was represented to reduce by adding alcohol. The solubility of L-ornithine aspartate with temperature incressed at methanol volume ratio 40%, but was slightly effected at methanol volume ratio 60% and 80%. The effect of aspartic acid was not signifigant, too.
