목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

Kim,Ik-Hwan,Kim,Hag-Hyun,Hong,Eui-Yon,Yun,Jong-Sun,Yun,Tae,Hwang,Ju-Kwang,Lee,Cheol-Hee 한국자원식물학회 2003 Plant Resources Vol.6 No.3

Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Codonopsis lanceolata. Three tetraploid plants of C. lanceolata were produced from seeds which absorbed 0.1 % colchicine solution for 12 hours, and 0.5% colchicine solution for 1 and 6 hours from seedlings, respectively. But tetraploid was not produced from shoot tips treated by colchicine solution. Compared to diploid, tetraploid plants had larger stomata, but less number of stomata. Fresh weight of tetraploid plants was 1.4∼3.6 times heavier than diploid plants.

빠르며 정확하고 안전한 치아이동을 목표로 삼고 있는 교정치료에서 최근 새로이 도입된 피질골 절제술과 견인 골형성술을 응용한 치아이동에 대하여 알아보았다. 특히 견치나 대구치의 후방이동은 기존의 치아 이동 양식으로는 조절이 어렵고, 장기적인 기간에 불가피한 치아이동이다. 피질골 절제술과 견인 골형성술을 동반하여 상당히 효과적인 원심이동을 기할 수 있었던 증례를 통하여 적용 술식, 견인 장치 등을 논하고 그효과를 파악하였다. 이런 술식을 통해 빠른 치아 이동과 이에 따른 전반적인 치료기간의 감소가 가능하였으며, 무리한 치아이동에서 발생할 수 있는 고정원 소실이나 치근흡수, 치주조직의 파괴 같은 부작용도 줄일 수 있었다. Tooth movement facilitated by corticotomy and distraction osteogenesis was discussed. In this study, a portion of cortical bone which can provide resistance to tooth movement in alveolar bone was removed. Active bone deposition was then possible in the tension side. Teeth moved at such a speedy rate as we could not imagine from conventional orthodontic treatment, which lead to the reduction of the total treatment period. Posterior movement of the canine or molar teeth was possible without any side effects such as anchorage loss, root resorption or periodontal breakdown.

Breeding of Tetraploid in Platycodon grandiflorum (Jacq.)A. DC. by Colchicine treatment

Kim,Ik-Hwan,Kim,Hag-Hyun,Hong,Eui-Yon,Yun,Jong-Sun,Yun,Tae,Hwang,Ju-Kwang,Lee,Cheol-Hee 한국자원식물학회 2003 Plant Resources Vol.6 No.3

Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Platycodon grandiflorum in Campanulaceae. The most successful colchicine treatment for tetraploid production in P. grandiflorum was soaking treatment using 0.01 and 0.5% colchicine solution for 1 hour and 12 hours, respectively. Morphological characteristics of both diploid and tetraploid were similar, but tetraploid plants had more leaves. Compared to diploid, tetraploid had the larger stomata, but less number of stomata. Fresh weight of tetraploids was 20∼40% heavier than that of diploid.

In order to obtain the basic data for artificial maturity control of 'Mibaek' peach, GA and ethephon were foliar sprayed 4 weeks prior to harvest, and their effects on fruit maturity and quality were examined. GA and ethephon tended to decrease the fruit weight except 100mg ㆍ L-1 GA+50 to 100mg · L-1 ethephon treatment. GA increased the fruit firmness, and ethephon at higher concentration increased the fruit drop. Harvest date was advanced for 7 to 8 days by ethephon while was delayed for 6 to 8 days by GA treatment, regardless of concentration.

스트레스 반응에 중요한 역할을 하고 있는 CRHR1 유전자 SNP와 알코올 의존과의 연관성에 관한 선행 연구들이 있다. 이에 본 연구는 백인을 대상으로 조사했던 기존연구와는 달리 한국인 남녀를 대상으로 하여 알코올 의존군과 정상 대조군의 CRHR1 유전자형 빈도 및 대립유전자형 빈도를 비교하였다. 본 연구의 연구대상자들은 알코올 의존군 268명(남자 218명, 여자 50명)과 정상 대조군 137명(남자 78명, 여자 59명)이었다. CRHR1 유전자 SNP를 SNP database와 선행연구를 근거로 선정한 후, 연구 대상자들의 이러한 SNP 유전자형을 PCRRFLP방법으로 조사하였다. 그 결과, 한국인의 CRHR1 유전자 SNPs로 7개(rs242938, rs404623, rs28364027, rs16940686, rs937, rs878886, rs878887)가 분석되었다. 이중 rs28364027의 A 대립 유전자의 빈도는 남녀 각각에서 알코올 의존군이 대조군보다 유의하게 높았다. 그리고 rs28364027의 AA 유전자형 및 A 대립 유전자와 rs878886의 CC유전자형 및 C 대립유전자의 빈도는 알코올 의존군내에서 여성이 남성보다 유의하게 높았다. 이러한 결과를 종합해 보면 CRHR1 유전자 SNP가 알코올 의존의 유전적 원인의 중요한 요인일 가능성을 제시하고 있다. 또 이러한 CRHR1 유전자 SNP가 알코올 의존의 유전적 원인에서 남녀간 차이를 설명할 수 있을 가능성도 시사하고 있다. Objectives:There were several preceding studies investigating the association between alcohol dependence and corticotropine releasing hormone receptor1(CRHR1) gene SNPs that play an important role in response to stress. The frequencies of CRHR1 genotypes and alleles were compared between alcohol-dependent patients and normal control subjects. Methods:The subjects were 268 alcohol-dependent patients(218 males, 50 females) and 137 normal controls(78 male, 59 female). CRHR1 gene SNPs were investigated according to the SNP database and the results from previous studies, and their genotypes were analyzed by polymerase chain reaction(PCR) and restriction fragment length polymorphism(RFLP). Results:Seven CRHR1 gene SNPs(rs242938, rs404623, rs28364027, rs16940686, rs937, rs878886, rs878887) were found in Korean subjects. The frequency of rs28364027 A allele was significantly higher in alcohol-dependent patients than normal controls in both genders. In alcohol-dependent patients, the frequencies of AA genotype and A allele of rs28364027, and of CC genotype and C allele of rs878886 were higher in female than male. Conclusion:These results suggest that CRHR1 gene SNP is one of the important genetic factors in the etiology of alcohol dependence. And also it is supposed that the different frequency of SNP genotype could explain stress-related gender difference in the genetic etiology of alcohol dependence.

Objectives : There are a number of preceding epidemiological studies reporting gender differences in the genetic etiology of alcohol dependence. The author investigated gender difference in the frequencies of ADH2 and ALDH2 genoypes between the patients with alcohol dependence and normal control. Methods : The subjects were 141 alcohol dependent patients (104 males, 37 females) and 138 normal control (79 males, 59 females). The frequencies of 1/1 and 1/2+2/2 (2+ afterward) genotypes for ADH2 and ALDH2 were investigated in male and female between alcohol dependence and normal control group. DNA was extracted from WBC in peripheral venous blood and PCR-RFLP method was used out for genotyping. Results : First, the frequency of ADH2 1/1 genotype was significantly higher in alcohol dependent patients than normal control in both genders. Second, while there was no gender difference in the frequency of ADH2 1/1 genotype in normal controls, in the patient group however, the frequency was significantly higher in females than males. Third, in male subjects with alcohol dependence, the frequency of ALDH2 1/1 genotype was significantly higher than in male normal control subjects. On the other hand, in female subjects with alcohol dependence, the frequency of ALDH2 2+ genotype was significantly higher than in female normal control subjects. Conclusion : These results suggest that while the risk of alcohol dependence is predominantly affected by ALDH2 1/1 geno-type in male, the female ADH2 1/1 genotype is mainly associated with the risk of alcohol dependence. This means that there are gender differences in the genetic etiology of alcohol dependence.

<P><B>Abstract</B></P> <P>Chronic exposure to cadmium (Cd) causes remarkable damage to the kidneys, a target organ of accumulated Cd after oral administration. The aim of the present study was to investigate the protective effect of curcumin against Cd-induced nephrotoxicity. Sprague–Dawley male rats were divided into the following four treatment groups: control, curcumin (50 mg/kg, oral), CdCl<SUB>2</SUB>, (25 mg/kg, oral), and pre-treatment with curcumin (50 mg/kg) 1 h prior to the administration of CdCl<SUB>2</SUB> (25 mg/kg, oral) for 7 days. At 24 h after the final treatment, the animals were killed, and the biomarkers associated with nephrotoxicity were measured. Our data indicated that blood urea nitrogen (BUN) and serum creatinine (sCr) levels were significantly reduced by curcumin pre-treatment in CdCl<SUB>2</SUB>-treated animals. Histopathological studies showed hydropic swelling and hypertrophy of the proximal tubular cells in the renal cortex after Cd treatment. Pretreatment with curcumin ameliorated the histological alterations induced by Cd. The urinary excretion of kidney injury molecule-1 (Kim-1), osteopontin (OPN), tissue inhibitor of metalloproteinases 1 (TIMP-1), neutrophil gelatinase-associated lipocalin (NGAL), and netrin-1 significantly reduced by curcumin treatment compared to that in the CdCl<SUB>2</SUB>-treated group. The administration of curcumin provided a significant protective effect against Cd-induced nephrotoxicity.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Curcumin protects against cadmium-induced renal injury. </LI> <LI> Curcumin reduces urinary excretion of AKI biomarkers. </LI> <LI> Curcumin protects against cadmium-induced apoptosis in the kidney. </LI> </UL> </P>
