본 연구는 사상체질인 태음인, 소음인 그리고 소양인간의 유전적 상관관계를 Random Amplified Polymorphic DNA(RAPD) 분석법 및 ABO 유전자형의 대립유전자의 빈도 분석을 통하여 실시하였다. 체질간 DNA 다형성을 검출할 수 있는 RAPD 분석용의 primer의 빠른 선별을 위해 체질별 혼합된 DNA 시료를 분석에 사용하였다. 일차적으로 200종류의 RAPD primer로부터 다형성을 보이는 7종류의 primer를 선별하였다. RAPD밴드로터 체질간 bandsharing(BS) 값은 0.68에서 0.71범위에 있었고, 유전적 거리는 BS 값에 의해 구했다. RAPD의 BS값에 의한 태음인과 소음인간 유전적 거리는 0.002이고, 이 두 체질과 소양인간에는 0.005로 분석되었다. 또한 체질별 ABO 유전형을 조사하여 그들의 대립유전자 빈도를 추정해 체질간 유전적 거리를 산출했다. 그 결과 태음인과 소음인사이에 유전적 거리는 0.014이고, 소양인과 나머지 두 체질간에는 0.032였다. 위와 같이 RAPD 분석법과 ABO 대립유전자의 빈도분석에 의한 체질간 상관관계는 두 방법 모두에서 태음인과 소음인이 소양인 체질보다 유전적으로 더 가깝게 나타났다. This study was carried out to be establish genetic understanding of Sasang constitutions of Teaumin, Soumin and Soyangin by Random Amplified Polymorphic DNA(RAPD) and ABO alleles frequencies analysis. We have applied RAPD analysis to pooled DNA sample as a means to achieve rapid screening of large numbers of primers for their capacity to reveal constitutions-specific polymorphisms. From initial 200 primers, 7 polymorphic primers between different constitutions were selected. The RAPD bandsharings(BS) values ranged from 0.68 to 0.71 for between three constitutions. The genetic distance between three constitutions was measured by BS values. Genetic distance by RADP analysis was 0.002 between Teaumin and Soumin, and 0.005 between Soyangin and the others. Three Sasang constitutions were investigated by the genotyping of ABO genotypes, and genetic distance was calculated from ABO allele frequencies in each constitution. As a result, genetic distance was 0.014 between Teaumin and Soumin, and 0.032 between Soyangin and the others. In conclusion, the genetic distance of Teaumin and Soumin was closer than that of Soyangin in the analysis of RAPD and ABO alleles frequencies.

<P><B>Background</B></P><P>This study was performed to evaluate the effects and stability of the new hepatitis B immunoglobulin (HBIG), Hepabulin, in patients undergoing liver transplantation for hepatitis B.</P><P><B>Material/Methods</B></P><P>A total of 87 patients undergoing liver transplantation for hepatitis B-related liver disease were enrolled in this multicenter, phase III, open-label, single-arm study. Seventy (80.5%) of the 87 enrolled patients completed the study during the 52-week study period. Hepabulin (10,000 units) was intravenously injected intraoperatively, daily for 1 week, weekly for 1 month, and then once per month. Hepabulin was used as monotherapy without antiviral agents. Hepatitis B recurrence was defined as conversion from negativity for surface antigen after HBIG administration to positivity.</P><P><B>Results</B></P><P>There were no cases of hepatitis B recurrence during the 52-week observation period. A total of 876 adverse events (AEs) that occurred during the study period were observed in 83 (95.4%) of 87 patients, and serious AEs were seen in 119 cases in 44 (50.6%) of the 87 patients. None of the AEs showed a relationship with this drug. Hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) rapidly disappeared within 1 week after HBIG administration, but hepatitis B virus (HBV) DNA persisted for up to 8 weeks after surgery, which was related to HBV viral load. Hepatitis B surface antibody (HBsAb) was correlated with HBIG (Hepabulin) dose.</P><P><B>Conclusions</B></P><P>The new HBIG, Hepabulin, was shown to be safe and effective in preventing the recurrence of HBV after liver transplantation.</P>

Hepatocellular carcinoma (HCC) in the caudate lobe remains one of the most intricate locations where various treatments tend to pose problems with regard to the optimal approach. Surgical resection has been regarded as the most effective treatment; however, isolated resection of the caudate lobe is strenuous and associated with a high rate of early recurrence. Percutaneous ablation might be technically difficult or impossible to perform due to the deep location of tumors and adjacent large vessels. Treatment with drug-eluting beads (DEB) can potentially enhance the therapeutic efficacy for patients with unresectable HCC by drawing on the slower, more consistent drug delivery process. We described a case of a 62-year-old man with HCC in the caudate lobe who was successfully treated by DEB. (Korean J Hepatol 2010;16:405-409)

Mushroom is the only microorganism cultivated as the crop, and Plerotus ostreatus is one of the most important edible mushrooms. Efficient production of edible mushrooms relies on the precise control of fruiting body development, and an identification of the molecular mechanism of fruiting body development has commercial and scientific importance. In order to identify the developmentally regulated genes during fruiting body development, cDNA libraries were constructed from eight developmental stages of the P. ostreatus. From these libraries, 11,761 expressed sequence tags (ESTs) were generated. Based on these results, we performed macroarray analysis using 1,528 unigene clones at three developmental stages of mycelium, fruiting body and basidiospores. Plasmids isolated from these clones were blotted on the nylon membrane. The isotope-labelled cDNA probes for hybridization of the northern blot were prepared from total RNAs isolated from three developmental stages of mushroom. The 33, 14, 10 unigenes were very highly expressed in mycelia, fruit body and basidiospores, respectively. To confirm expression pattern of these genes, RT-PCR was performed using the total RNA isolated from three developmental stages. Seven genes were successfully amplified in RT-PCR. The expression patterns of the genes were similar with that in macroarray. One of seven genes was identified as a 12kDa heat shock protein and its expression level was very highly at fruiting stage, but not detected at mycelium stage.
