목적: HBV 감염이 무증상의 자연 회복부터 간경변 혹은 간세포성 간암까지 다양하게 나타나는 요인들로 숙주의 요인과 바이러스의 요인으로 구분되어 제시되는데, 바이러스 요인으로는 감염된 바이러스이 유형이나 염기 변이들이 논의된다. HBV 유형을 구분하는 데는 혈청형과 유전자형이 이용되는데 근자에는 주로 유전자형이 이용된다. 이러한 HBV의 분포는 지역적으로 다르나 지역에 따라서 다른 유형들이 혼재되어 있다. 동남아시아는 B형이지만 극동아시아는 C형으로 알려져 있으며, 대만과 오키나와에서는 B와 C형이 혼재되어 나타난다. 이러한 결과로 미루어 보아 우리 나라의 남부지역에서는 B과 C형이 혼재되어 있을 가능성이 있다. 이에 본 연구는 제주 지역에서 HBV의 유전자형을 조사하고자 하였다. 대상과 방법: 원적지가 제주도이면사, HBsAg가 양성이었던 107명(평균 연령: 46.5세)을 대상으로 하였다. 이들의 혈청으로부터 HBsAg/antiHBe를 분석하고, DNA를 추출하여 7개의 유전자형에 따라 특이성을 갖는 시발체(genotype specific primer)들을 이용하여 PCR로 증폭한 후 이를 분석하였다. 주된 유전자형의 일부와 다른 유형에서 증폭에 이용되었던 시발체를 다르게 이용하여 hemi nested PCR로 증폭한 후 염기를 분석하여 계통발생학적 분석법을 이용하였다. 결과: 1. PCR에 의한 HBV DNA 양성은 107명 중 59명(55.1%)이 양성이었다. HBeAg/anti HBe의 발현 양태에 따라 음성/음성에서 2명(66.7%), 음성/양성에서 30명(41.1%), 양성/음성에서 24명(85.7%), 양성/양성에서는 3명(100%)에서 증폭되었다. 2. Multiplex PCR에서는 58명의 유전자형이 C형, 1명에서는 B형과 C형이 동반 출현하였다. 3. Genotype specific primer를 이용하여 각각 따로 PCR을 시행한 경우에 A형에 의하여 증폭된 예가 1예, B형에 의하여 증폭된 예가 1예, C형에 의하여 증폭된 예가 59예로 A형과 B형 모두가 C형에서 증폭된 예였다. 4. 한 쌍의 시발체에 의하여 증폭되었던 A형과 B형 및 C형의 일부에서 염기를 분석한 결과 모두 C 유전자형이었다. 결론: HBsAg이 양성인 제주 지역 주민의 HBV의 유전자형은 C형일 것으로 생각된다. Background/Aims: Hepatitis B virus (HBV) was classified into 8 genotypes by a sequence divergence in the entire genome designated from A o H. HBV genotypes have distinct geographic distributions. Recently, HBV genotypes have been partially found as influencing the clinical manifestation of chronic liver disease in hosts. In Korea, the distribution of HBV genotypes remains unclear. The aim of this study was to evaluate the prevalence of the HBV genotype on Jeju Island. Methods: Hepatitis B virus genotypes were evaluated among 107 hepatitis B carriers residing on Jeju Island. We used single PCR and multiplex-PCR assay with genotype-specific primer pairs for HBV genotypes A-F for the genotyping. Results: 1. Fifty nine samples (55%) were positive for HBV DNA. The positivity was different according to the pattern of HBeAg/anti-HBe expression, as -/-; 2/3 (66.7%), -/+; 30/73 (30%), +/-; 24/28 (85.7%) and +/+; 3/3 (100%). 2. In the single primer set of genotype-specific PCR, 59 samples (100%) were detected as genotype C and 2 (3%) were also detected as genotype A and B. 3. In multiplex-PCR, 58 samples (98%) were detected as genotype C and only one (2%) as a mixed pattern of genotype B and C. 4. When the PCR products were amplified with universal sense and genotype specific anti-sense from one genotype A, one B, and 2 C, all were included in genotype C. Conclusions: These results suggest that on Juju Island, almost all HBV genotypes are C.(Korean J Hepatol 2004;10:42-50)

Objectives:This study was to identify weight & metabolic changes in first-episode psychotic patients with antipsychotics use and investigate the differences of weight & metabolic changes between first-episode psychotic patients and controls with antipsychotics use. Method:In this retrospective study, twenty eight first-episode psychotic patients and twenty eight controls with schizophrenia, schizoaffective or bipolar disorder defined by DSM-IV criteria were included. Information about demographic and clinical characteristics of the subjects was gathered from the medical records. Also body weight, sBP, dBP, fasting glucose, lipid profile and WBC count were evaluated before and after antipsychotics use. Rogistic regression was conducted to assess factors associated with weight gain. Results:First-episode psychotic patients showed more weight and BMI changes than controls after antipsychotics use, and these changes continue over 12 months. On the other hand, there were no significant factors associated with weight gain. Conclusion:The results of present study suggest that antispychotics is one of the major causes inducing weight gain of psychotic patients and antipsychotics-induced weight gain is more vulnerable to drug-naive first-episode psychotic patients.
A Case of Zoster Duplex Bilateralis Korea
(Joo Hyun Shim),(Bong Ju Shin),(Seong Jun Seo),(Chang Kwun Hong) 대한피부과학회 2002 Annals of Dermatology Vol.14 No.1
N/A Herpes zoster involving noncontiguous dual dermatomes is very rare in both immunocompetent and immunocompromised persons.This unique presentation has been referred to as zoster duplex unilateralis or bilateralis,depending whether one or both halves of the body are involved.A 22-year-old woman, who had been treated for acute leukemia, congestive heart failure and chronic disseminated candidiasis, was referred to our department for painful papulovesicular eruptions on the right side of the anterior chest and upper back for 2 days, and the left buttock for 1 day. Tzanck smear revealed multinucleated giant cells with intranuclear inclusion bodies. We report a rare case of zoster duplex bilateralis. (Ann Dermatol 14(1) 59-61, 2002).

The overall incidence of skin malignancies, mostly non-melanoma skin malignancies were known to be about 6-fold higher in patients with severe psoriasis than in the general population. Non-melanoma skin cancer in psoriasis patients had been reported to be associated with psoriasis treatment such as long-term use of psoralen plus ultraviolet light (PUVA) and/or immunosuppressives rather than psoriasis itself. We report four cases of squamous cell carcinoma arising in a psoriasis patient. Two patients had received immunosuppressive agents and PUVA for psoriasis treatment, whereas the other two did not have any history of using immunosuppressives but only topical therapy and narrowband UVB (NB-UVB) light. Although this report includes small number of cases, dermatologists should be consider the association of an increased risk of nonmelanoma skin cancers with psoriasis itself as well as the long use of immunosuppressives and phototherapy.

e-Navigation strategy IMO promotes is defined as it is necessary for network and information standard to provide various maritime safety informations to in land and on board users, and it is expected to provide a large amount and diverse kinds of maritime spatial information services to them. However, as there are some limits to transmit that by current mobile maritime communication technologies, it is required to simplify and optimize the information. In this study, tree node method is applied to ENC using Douglas-Peucker algorithm and we arranged the effect of simplified spatial information through CALS method which compensates the defect of basic tree node method.

Background/Aims: RUN×3 (PEBP2αC/CBFA3/AML2) is a novel tumor suppressor gene in the human gastric carcinoma. The aims of this study were to determine the methylation of RUN×3 promoter and the association between RUN×3 methylation and the clinicopathological characteristics of patients with gastric carcinoma. Methods: Seventy-nine patients with gastric carcinoma were studied prospectively from April 2005 to May 2007. The methylations of RUN×3 promoter on the gastric carcinoma specimens and the corresponding nonneoplastic mucosa were evaluated by methylation-specific polymerase chain reaction. Results: Comparison of the results with the clinicopathological characteristics identified RUN×3 monoallelic methylation in 32.9% (26/79) of the gastric carcinoma patients and in 11.4% (9/79) of those with nonneoplastic mucosa (p=0.053). The monoallelic methylated gastric carcinoma specimens predominantly consisted of well- and moderately differentiated carcinomas (44.7%), with the unmethylated group constituting 22.0% of them (p=0.031). Among the 48 patients (60.8%) who underwent gastrectomy, there was no correlation between the two groups with regard to Lauren`s classification (p=0.235), depth of invasion (p=0.990), nodal status (p=0.601), stage (p=0.900), lymphatic invasion (p=0.537), and vascular invasion (p=0.815). Conclusions: Methylation of the tumor suppressor gene RUN×3 might be one of the mechanisms involved in the pathogenesis of gastric carcinoma.
