목적: 백혈병 환자의 사지와 척추 등에 발생하는 과립구 육종(녹색종)은 매우 드물고 그 치료나 예후도 확립되어 있지 않다. 본 연구에서는 과립구 육종 20 예를 대상으로 그 발병기전, 임상적 경과와 치료 결과를 보고하고자 한다. 대상 및 방법: 1998년 4월부터 2004년 9월까지 본 대학 혈액 종양 센터 및 정형외과학교실에서 치료한 총 2,197명의 백혈병 환자 중 척추 및 사지에 이환되었던 과립구 육종 20명(0.91%)을 연구 대상으로 하였고, 1-78개월(평균18개월)간 추적관찰하였다. 결과: 과립구 육종의 발생 빈도는 1998년 4월부터 2004년 9월 까지 6년 5개월 간 본 대학 혈액 종양 센터에서 가료한 급성 골수성 환자 1,331명중 15례, 만성 골수성 환자 744명중 4례, 혼합형 급성 백혈병 환자 122명중 1례가 발생하여 전체 백혈병에서의 발생율은 2,197명 중 20명이 발생하여 0.91%의 빈도를 보였다. 평균 연령은 28.3세(4~52)였고, 남자 13명, 여자 7명이었다. 단발성 병변은 11례, 다발성 병변은 9례였으며, 병변은 척추 12례, 뇌실질 5례, 사지 6례, 흉부 2례, 골반부 2례, 두개골 및 안구에 각각 1례씩 발생되었다. 과립구 육종은 급성 골수성 백혈병(acute myelogenous leukemia, AML)환자 15명, 만성 골수성 백혈병(chronic myelogenous leukemia, CML) 환자 4례에서 그리고 혼합형 급성 백혈병(acute biphenotype leukemia) 환자 1례 등 총 20명 환자에서 발생하였다. 백혈병의 치료 과정중 과립구 육종의 발병 시기별로는 완전 관해 되었을 때 발병한 것이 8례, 특히 이중에서 4례는 만성 골수성 백혈병이 급성 백혈병으로 재발 악화 되면서 육종이 발병하였고, 나머지 12례는 급성 골수성 백혈병 환자의 치료 과정 중 과립구성 육종이 병발하였다. 6례에서의 조직 검사상 미성숙한 골수모세포와 림파구 등이 혼재된 전형적인 과립구 육종을 확진하였고, 과립구 육종의 치료는 전예를 백혈병의 재발 또는 진행과정에 따라 글리벡 및 스테로이드를 이용한 백혈병 자체에 대한 항암치료만을 시행하였고, 6예에서는 항암치료와 함께 과립구 육종에 대한 국소 또는 전신 방사선 치료를 병합하였다. 평균 18개월의 추시 기간 중 만성 골수성 환자의 경우는 4명 모두 사망하였고, 전체 환자는 모두12명(12/20: 60%)이 과립구성 육종의 발병이후 6.5 개월 만에 사망하였으며, 연령과 예후는 고령 발생시 더욱 불량하였다. 결론: 백혈병 환자에서 발생한 척추 및 사지의 과립구 육종의 예후는 불량하였고, 특히 만성 골수성 환자에서 발생시 예후가 더욱 불량하였으나, 급성 골수성 환자의 경우는 반드시 불량한 예후를 보이는 것은 아니여서, 백혈병 자체에 대한 적극적인 항암 치료와, 사지 과립구 육종에 대한 방사선 치료의 병합 요법이 필요하였다. Purpose: The granulocytic sarcoma which developed in leukemic patients are quite rare and it will have bad prognosis, but it's tumor pathogenesis and also their treatment are not yet established. Through this study we have tried to know their clinical course, prognosis and their end result of recent treatment. Material and Methods: Total 20 patients of granulocytic sarcoma which were developed in total 2,197 leukemic patients from April, 1998 to September, 2004 were treated at the leukemic center and the orthopaedic department of St. Mary's hospital, Catholic University of Korea, and followed them for 1~78 months(average 18 months). Results: Total 20 cases of granulocytic sarcoma was found in 14 cases of total 1,331 acute myelocytic leukemic patients(AML), 4 cases of total 744 of chronic myelocytic leukemic patients(CML), and only one case in total 122 of acute biphenotype of leukemia. And so their occurrence rate in leukmic patients are actually 0.91%, total 20 cases of granulocytic sarcoma in total 2,197 leukemic patients at same period. Their ages are average 28.3 years(4~52 years), and male are predominant(13 cases) than female(7 cases). Single involvement was found in 11 cases but multiple lesions are in 9 cases, and spine, brain, extremities, chest, and pelvic bone are involved in frequency. The granulocytic sarcoma was developed in various stages of the leukemia, ie, 8 cases in complete remission of leukemia, and 12 cases in the treatment process of AML. The pathohistologic evaluation of granulocytic sarcoma was done in 6 cases which was developed in their extremities, and confirmed numerous immature myeloblasts and lymphocytes mixed. The treatment of these granulocytic sarcoma was mainly limited for the treatment of leukemia by Glivac and massive steroid therapy(19cases) and also combined with the bone marrow transplantation(13 cases), but radiation therapy with average 3,500 rads in 15 cases out of total 20 sarcomas was also done, and followed them for average 17.5 months after development of granulocytic sarcomas. Finally their prognosis was so bad that 12 patients(60%) out of total 20 granulocytic sarcoma were dead in 6.5 months after sarcoma developed and we found the granulocytic sarcoma was more fatal if they are developed during the process of CML(mortality: 100%(4/4cases). Conclusion: The prognosis of granulocytic sarcomas in leukemic patients are quite fatal, and much more studies for their pathogenesis and ways of treatment should be performed continuously.

Objective : The authors investigated the efficacy of the calcium sulfate(OsteoSet$^{(R)}$ pellets) as an autograft extender when used to perform posterolateral lumbar fusions. Patients and Methods : Twenty patients who underwent lumbar posterolateral arthrodesis for various spinal diseases between October 1999 and March 2000 were evaluated. Arthrodesis was performed by transpedicular screw fixation and bone grafting with a mixture of autograft + calcium sulfate in a 1 : 1 ratio. At time intervals of 1, 2, 3, and 6 months, postoperative radiographs were obtained to review the resorption of calcium sulfate and the evidence of fusion. A modified Lenke scale was used to assess the status of the fusion. Results : At 2 months after operation, the average modified Lenke scale score for the OsteoSet$^{(R)}$ pellets group was 3.8. However at 6 months after operation, the average modified Lenke scale score for the OsteoSet$^{(R)}$ pellets group was 1.8. Resorption of calcium sulfate pellets was revealed in all cases at 6 months after surgery. Conclusion : It is presumed that a combination of calcium sulfate and autograft can play a role as an effective autograft extender in the posterolateral spinal fusion.

Object Although Taeeum and Soyang constitutional types have bigger body shapes and higher body mass index values than those with the Soeum, the relationship between the Sasang constitutional type and bone mass density is controversial and the association of osteopenia and osteoporosis remains unknown. Therefore, we investigated the relationship between bone mineral density, osteopenia, and osteoporosis according to Sasang constitutional type. Methods A total of 2,508 participants were included in this study. Among the study participants, 1,396 had Taeeum type, 276 had Soeum type, and 836 had Soyang type, respectively. The relationships to bone mass density, osteopenia, and osteoporosis in those with Sasang constitutional type were estimated using logistic and linear regression models. Results Bone mass density was significantly higher in the order of Taeeum, Soyang, and Soeum group (p < 0.01). Soeum group in comparison with Taeeum or Soyang group was significantly associated with a high odds ratio for osteopenia and osteoporosis except in the hip and femoral neck in the comparison of Taeeum and Soeum group (p < 0.01). Moreover, the bone mass density of Soeum group decreased more rapidly as the age increased when compared with Taeeum and Soyang group. Conclusions Our findings may contribute to the early prevention and management of high-risk individuals with poor bone mass density, osteopenia, and osteoporosis using Sasang constitution medicine.

Broccoli is considered as one of the functional foods to offer a hearty supply of the nutrient- rich vegetable in the world. Broccoli contains high level of phytochemicals, and that is selected as one of the top 10 vegetables for human health promotion. Especially, glucosinolates and flavonoids are well known as anti free oxygen radicals in vegetables and fruits. In Korea, broccoli consumption has increased to well known on the health-beneficial vegetables since 2000. However, broccoli has many problems of postharvest management since the quality of harvested heads quickly declines. Major problems are the floret yellowing, wilting, off-odor, and decay. The multiple postharvest applications improve broccoli quality and cold treatment including pre-cooling extends on the shelf-life with circumstance of optimum storage which is 0oC temperature and a range of 95-100% relative humidity. Controlled atmosphere or modified atmosphere packaging can be used as supplemental treatments to extend postharvest life. 1-2% O2 + 5-10% CO2 is currently recommended for broccoli. Postharvest management is important for broccoli because price fluctuations depend on harvest time and quality. In this study, we tried to review physiological change of broccoli after the harvest, storage method, and various techniques to optimize quality during distribution.

A needle-free injector is one of the new non-invasive players in impregnating the biological barriers. It is considered as the next phase in drug delivery and therapeutic applications. One of the major fields of application is in skin remodeling procedures. Although many studies were carried out in understanding the principle in the needle-free injection procedure, fewer studies were done with the aim of therapeutic applications. In the present study, we tried to identify key parameters that affect the jet divergence and peak stagnation pressure on the skin surface in a conventional needle-free injector for skin treatment. A summary of the working principle and effect of the key parameters are presented.

There has been no genome-wide association study (GWAS) for macronutrient intake as a quantitative trait. To explore genetic loci associated with total calorie and macronutrient intake, genome-wide association data of autosomal single nucleotide polymorphisms (SNPs) from Korean adults were analyzed. We conducted a GWAS in 3,690 men and women aged 40 to 60 years from an urban population-based cohort. At the baseline examination (June 18, 2001 through January 29, 2003), DNA samples of the study subjects were collected and analyzed for genotyping. The information of average daily consumption of total calorie, carbohydrate, protein, and fat was obtained from a semi-quantitative food frequency questionnaire and transformed by natural logarithm for analyses after adjustment of calorie intake. Using multivariate linear regression analysis adjusted for age, sex, and height, we tested for 352,021 SNPs and found weak associations, which do not reach genome-wide association significance, with calorie and macronutrient intake. However, a number of SNPs were found to have potential associations with macronutrient intake; in particular, signals in SORBS1 and those in PRKCB1 were likely associated with carbohydrate and fat intake, respectively. We observed an inverse association between the minor allele of the SNPs in these genes and the amount of consumption of carbohydrate or fat. Our GWAS identified loci and minor alleles weakly associated with macronutrient intake. Because SORBS1 and PRKCB1 are reportedly associated with the metabolism of glucose and lipid as well as with obesity-related diseases, further investigations on biological and functional roles of polymorphism of these genes in the relation to macronutrient intake are warranted.

Objectives:Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is characterized by abnormalities of social functioning, communication and behavior. The association of the 7q21-34 region with ASD has been reported. The DLX6 gene, which is located at the 7q22 region, is one of the positional and functional candidate genes for ASD. We found that there is no association between DLX6 polymorphisms and ASD in the Korean male population. Methods:We selected three single nucleotide polymorphisms (SNPs) that might be implicated in the change of the DLX6 gene expression. The genomic DNA was collected from the venous blood of 147 male controls and 179 male patients with ASD. The genotypes of the selected SNPs were determined using the Illumina GoldenGate assay, and the statistical analyses were performed using HapAnalyzer software and SAS Enterprise. Results:We found no association of the three SNPs in the DLX6 gene with ASD in the Korean male population. Conclusion:Our study suggests that the three SNPs in the DLX6 gene are not associated with ASD, and we need to analyze the previously reported regions for their associations with ASD.

본 연구가 VRSA에 대한 신규 항생물질 생산 균주를 얻기 위하여 실시하였다. 국내외에 채취한 토양시료에서 분리한 방선균 중, 임상분리 VRSA와 돌연변이 유발 VRSA에 대해 항균성을 나타내는 JY-24를 선별하였다. 선발 균주는 원통형의 포자 모양을 갖고 있으며, Bennett's 배지에 배양시 aerial mycelium color는 흰색을 나타냈으며, reverse side color는 대체로 노란색을 나타내었다. 항균물질 생산을 위한 탄소원으로는 fructose, mannose, 질소원으로는 yeast extract가 가장 우수하였으며 glucose의 첨가로 항균 물질 생산성이 증가하는 것으로 나타났다. 최적 초기 pH는 pH 7로 나타났으며, 28 ℃, 37℃, 45 ℃의 온도에서 균이 성장하는 것으로 나타났다. 또한 배양기간에 따라 항균물질 생산성을 조사한 결과, 임상분리 균주에 대해 5일 배양 시 가장 높았으나, 3일 배양과 7일 배양 시 동일한 생산성을 나타내 생산속도가 빠르며, 안정한 물질인 것이 파악되었다. 향후 균주동정 및 항균물질 정제에 관한 연구를 수행하고자 한다. An antibiotic substance producing strain JY-24, effective to the VRSA (Vancomycin-resistant Staphylococcus aureus), was isolated from soil. The spore chain of JY-24 was cylindrical, and its sulface was smooth. The aerial mass color of the strain was white, and its reverse side color was yellow. The strain did not produce soluble pigment. For the production antibiotics, fructose, mannose and yeast extract were favorable as carbon and nitrogen sources. Optimal initial pH for the production of the antibiotic was pH 7. Accumulation of the antibiotic in the culture broth reached at maximal level after 5 days cultivation in Bennett's medium.
