Background and Objectives: The aim of the study was to identify the factors associated with life satisfaction of hospitalized Vietnam veterans. Material and Methods: The data were collected from 200 hospitalized Vietnam veterans of 5 veterans hospitals in Korea from September 13 to 23, 2004. Information of general characteristics, health behavior, disease history, family function, depression and life satisfaction were collected by structured questionnaire. Results: The mean of life satisfaction was 21.48(±6.03), and the mean of depression was 53.10(±9.64). The prevalence of depression was mild depression 24.0%, moderate depression 43.5% and severe depression 25.0%. Depression was associated with life satisfaction and depression was higher, life satisfaction was lower. Family function and age were positively associated with life satisfaction, Conclusion: Life satisfaction was affected by depression and family function in hospitalized Vietnam veterans. Therefore, it was thought that psychosocial approaches such as improve depression and family function in care of hospitalized Vietnam veterans is required.

연구배경: 갑상선 수질암의 25∼30%는 유전성으로 발현되는데, MEN 2A, MEN 2B 또는 가족성 수질암의 형태로 나타난다. RET 원종양유전자의 점돌연변이가 유전성 갑상선 수질암의 발생에 중요한 역할을 하므로, 진단 당시의 연령이나 가족력 유무에 관계없이 모든 갑상선 수질암 환자나 또는 RET 변이가 발견된 수질암 환자의 가족 구성원들에서 RET 변이 검색을 하여야 한다. 또한 일부 문헌에서 RET 변이의 양상에따라 임상상이 다르게 표현됨이 보고된 바 있다. 이에 저자들은 한국인 갑상선 수질암 환자에서 RET 원종양유전자의 점돌연변이의 양성률을 알아보고, 변이 양상에 따른 임상상의 차이가 있는지를 알아보고자 본 연구를 시행하였다. 방법: 치근 7년간 본원에서 갑상선절제술을 통해 갑상선 수질암으로 진단받은 29예에서 RET 원종양유전자의 점돌연변이 검사를 시행하였다. 29예의 평균연령은 39세(20∼60세)이었고, 남자 7예, 여자 22예 이었다. 이들의 말초혈액에서 genomic DNA를 분리하고, 특이 시발차를 이용하여 RET 원종양유전자의 exon10, 11, 13, 14, 16부위를 증폭하였다. 증폭된 부위를 자동염기서열분석기를 이용하여 직접 분석하였다. 양성으로 나온 경우는 모든 가족 구성원을 대상으로 RET 변이 유무를 검색하였다. 결과: 대상 환자 29예 중 9예 (31%)에서 RET 원종양유전자 점돌연변이가 발견되었다 RET 변이가 발견된 9예 (남자 3예, 여자 6예)의 평균 연령은 33세 (20∼51세)로 RET 변이가 발견되지 않은 20예의 평균연령 42세(24∼60세)보다 의미 있게 적었다. RET 변이가 발견된 9예 중 MEN 2A가 5예, 가족성 수질암이 1예, 그리고 산발성 수질암이 3예이었고, MEN 2B는단 1예도 진단되지 않았다. MEN 2A 5예 중 4예는 exon 11의 codon 634번(C634R 2예, C634Y 2예)에서, 그리고 나머지 1예는exon 10의 codon 618번 (C618R)에서 변이가 각각 발견되었다. 가족성 수질암 1아는 codon 634번(C634W)에서, 산발성 수질암 3예도 모두 codon 634번 (C634y 2예, C634s 1예)에서 각각 변이가 발견되었다. RET변이 양상 또는 위치에 따른 임상상의 차이는 발견할 수 없었다. 결론: 갑상선 수질암 환자 31%에서 RET 원종양유전자의 점돌연변이를 발견할 수 있었다. 유전성 수질암 중 가족성 수질암 1예를 제외하고 나머지 5예는MEN 2A이었다. 저자들의 5예와 지금까지 국내에서 보고 된 7예를 합친 국내 MEN 2A 12예 중 75% (9/12)는 exon 11의codon 634번(C634R 4예, C634y 4예, C634w 1예)에서, 그리고 나머지 25% (3/12)는 exon 10의 codon618번(C618R 2예, C618s 1예)에서 변이가 발견되었다. 국내에서는 codon 634과 codon 618 두 곳에만 국한된 양상이었고, codon 634에서의 C634R 변이는 1/3에서만 나타났다. 비록 본 연구에서는 제한된 환자 수 때문에 변이 양상과 임상상의 관계를 규명할 수 없었지만, 향후 많은 수의 환자를 대상으로 전향적인 연구를 시행하여 genotype-phenotype 관계 규명을 하는 것이 필요하다. Background: Medullary thyroid carcinomas (MTC) have been reported as hereditary in about 25 -30% of cases. The identification of germline mutation in RET proto-oncogene is important in the diagnosis of hereditary MTC, and occurs in three forms: MEN 2A, MEN 2B and familial MTC (FMTC). To evaluate the prevalence of the relationship of RET proto-oncogene mutation and genotype-phenotype was studied in Korean patients with MTC. Methods: Genomic DNA was obtained from 29 patients, with MTC, who underwent a total thyroidectomy, between 1997 and 2003, at the Samsung Medical Center. There were 7 male and 22 female patients, with an average age of 39, ranging from 20 to 60 years. Exon 10, 11, 13, 14 and 16 of the RET proto-oncogene were amplified, with specific primers, using PCR. A sequencing analysis was performed on the PCR product using an automatic sequencing analyzer. Results: Nine of the 29 patients (31%) were identified as having RET mutations. The average age of these 9 patients was 33 years, ranging from 20 to 51, with a female to male ratio of 2. Five patients had MEN 2A and one had FMTC, with the other 3 thought to have non-hereditary (sporadic) MTC. The 4 patients with MEN 2A had RET mutations on codon 634 of exon 11 (2 patients, C634R; 2 patients, C634Y) and the other patient on codon 618 of exon 10 (C618R). One patient with FMTC had a mutation on codon 634 (C634W). Three patients with sporadic MTC had RET mutations on codon 634 (2 patients, C634Y; 1 patient, C634S). However, no genotype- phenotype relationship could be found, due to the limited number of patients. Conclusion: Thirty-one percent (9/29) of the patients with MTC had RET proto-oncogene mutations. Three-quarters (9/12) of the Korean patients with MEN 2A, including another 7 patients reported in 3 papers in Korea, had RET mutations on codon 634 of exon 11 (4 patients, C634R; 4 patients, C634Y; 1 patient, C634W), but a quarter (3/12) had mutations on codon 618 of exon 10 (2 patients, C618R; 1 patient, C618S). Although no relations could be found between the genotypes and phenotypes, extensive prospective studies will be required to verify this (J Kor SOC Endocrinol 18:360-370, 2003).

The severe extrusion of the maxillary [post.teeth after the early loss of the mandibular post.teeth makes the fabrication of the mandibular prothesis difficult, and without proper planning.the treatment results are often unsatisfactoy. Several treatment modalitys have been introducted to correct the interarch space deficency.:Reduction the occlusal surfaces,Crown lengthening,Endodontics & restorative approach,Extraction, Orthodontic intrusion and segmental osteotomy. Because of many advantages,conservative method is widely used if it has no particular limits of treatment adjustment, but the cases of surgical correction indication are found in clinical experience. In our clinic,we corrected severe extruded maxillary post.teeth by performance of a unilateral posterior osteotomy with superior repositioning of the segment and orthodontic intrusion using Skeletal anchorage system,so here we reported the cases with a study of documents.

Melamine-induced nephrotoxicity is closely associated with crystal formation in the kidney caused by combined exposure to melamine (Mel) and cyanuric acid (CA). However, there are few dosage-finding studies for toxicological evaluation of chronic co-exposure to Mel and CA. The objective of this study was to investigate the possible mechanism by which a Mel and CA mixture lead to renal toxicity in rats. Mel and CA were co-administered to rats via oral gavage for 50 days. Nephrotoxicity was determined by measuring blood urea nitrogen (BUN) and serum creatinine (sCr) levels. Relative kidney weights were significantly increased in rats after co-exposure to Mel+CA (63/6.3 or 630/6.3 mg/kg) mixtures. BUN and sCr levels were significantly increased after Mel and CA co-exposure. Taken together, significant increase in KIM-1, NGAL, and calbindin levels were observed in the urine of rats exposed to Mel+CA (63/6.3 or 630/6.3 mg/kg) compared with the corresponding control group. Histological analysis revealed epithelial degeneration and necrotic cell death in the proximal tubules of the kidney after co-exposure to Mel+CA (63/6.3 or 630/6.3 mg/kg). Our data suggest that Mel-mediated renal toxicity may be influenced by CA concentrations in Mel-contaminated milk or foods.

수박 종자에서 Pseudomonas pseudoalcaligenes subsp. citrulli의 분리를 위한 선택배지

金炯武,李光植 全北大學校 1993 論文集 Vol.36 No.-

A semiselctive agar medium(PSC) was developed for the isolation of Pseudomonas pseudoalcaligenes subsp. citrulli(Ps.c.) from watermelon seed. The medium contains following per liter : 20g proteose peptone #3, 5.0㎖ glycerol, 1.5g K2HPO4, 1.5g MgSO47H2O, 15g agar, 1㎎ ampicillin, 100㎎ cycloheximide 1㎖ 1.5% bromthymol blue, 1㎖ 1.0% methyl violet and 1㎎ vancomycin. Colonies of Ps.c. were 3-4㎜ in diameter, smooth, round, slight convext, dark green(lighter margin) and glistening after 5 days at 39C on the PSC medium. The recovery of 10 strains including ATTC type 29625, on PSC medium in comparison to KB ranged from 93% to 105%(mean 97.8%). Reduction in seed flora of 10 watermelon seed lots on PSC medium was 97.2%. Recovery of Ps.c. added to watermelon seed ranged from 91.3% to 103.4%(mean 96.7%).

대입 예비생들의 과학교과 충족도 분석

김채옥,김형관,김기수 漢陽大學校 基礎科學硏究所 1988 基礎科學論文集 Vol.7 No.-

1984학년도부터 실시된 새교육과정은 과학교육을 강화하여, 인문계 과정 학생들은 두 과목을 선택하여 이수하던 것을 네 과목 모두 이수하게 하고, 자연계 과정 학생들은 네 과목의 심층부분까지 이수하게 하였다. 그러나 1987학년도 대입학력고사부터는 과목이 조정되어 이수한 네 과목 중 인문계 학생들은 한 과목만을, 자연계 학생들은 두 과목(물리·화학 중 택일은 필수)을 선택하게 되었다. 그 선택방법은 학생들의 선호성향과 충족도에 따라 많은 차이를 보이고 있다. 1985학년도와 1986학년도 대입학력고사 인문계 지원자의 과학과목 선택을 보면 85,86학년도 공히 물리·화학이 0.9%, 화학·생물이 80% 정도를 차지하였다. 이 결과는 암기 과목에 치우친 면을 보였음을 말해주고 있다. 그러므로 본 연구에서는 현재의 고등학교 과학교육이 보편적 교양교육으로 학생들의 요구와 필요를 어느 정도 충족시켜 주는지를 알아 보았다. 그 결과 인문계 0.3%와 자연계 0.9%만이 과학수업을 100% 만족하고 있었고 15.7%와 24.5%가 80% 정도 만족하고 있었다. 한편 대도시에서 농어촌 지역으로 갈수록 과학수업의 충족도가 떨어지고 있음을 보였다. New curriculum reformed in 1984 reinforced the education of science in highschools so that the students of cultural science field were demanded to complete four science subjects instead of two as of old, and the students of natural science field were forced to study four science subjets more deeply than before. Howevere, syllabi have been changed from the 1987 proficency examination of university entrance so as to choose only one out of four science subjects completed for the students of cultural science field, and two(One of them should be physics or chemistry) for the students of natural science field. Thus the choice of subjects shows great difference according to the students preference and sufficiency. In case of the proficiency examination of university entrance in both 1985 and 1986, the preference rate of science subjects for the applicants of cultural science field was 0.9% for physics and chemistry, about 80% for chemistry and biology. This means that the students of this field prefer subjects to memorize its contents easily and blindly. This work, therefore, ideals with whether the education of science in highschool, which is one of the liberal arts courses, satisfies the students needs and necessary. The result shows that only 0.3% of the students in cultural science field and 0.9% of the students in natural science field satisfy perfectly or 100%, but 15.7% and 24.5% of students in each field satisfy nearly or 80%. On the other hand sufficiency of science courses is high in large cities and is decreased as going down to the rural communities.
