Objective : The aim of this study were to measure quality of life(QOL) in liver transplant recipients, to compare QOL between living donor liver transplant recipients and cadaveric liver transplant recipients and to investigate whether SF-36 may be used as a disease-specific instrument in liver transplant recipients. Methods : We conducted a single-center cross-sectional study of 133 LT recipients ages 13 to 65 years, all of whom had had Liver Transplantation(LT) at least 1 months previously. QOL was assessed using a self-completion questionnaire consisting of the Bang Whal Ran(1991) instruments and the 36-Item Short-Form Health Survey(SF-36) health status profile measure. We investigated whether the SF-36 instrument may be used as a disease-specific instrument in LT recipients. Individual scale scores range from 0 to 100, with higher score reflecting better health. Data on demographics, clinical status at pre transplantation 1 day, post transplantation clinical status, and graft function were collected to identify predictors of post transplantation QOL. Results : Standard measures for test-retest reliability, internal consistency, and discriminant and concurrent validity were examined. The reliability of the SF-36, as measured by test-retest correlation(Pearson coefficients: 0.729, p=0.002) and by internal consistency(Cronbach's alpha: 0.9431) exceeded conventional acceptability criteria. The correlation between domain scores of SF-36 and the Bang Whal Ran(l991) was clear and logical in that the clinical characteristics of SF-36 strongly correlated with the clinical component summary score of the Bang Whal Ran(l991)(r = 0.8155, P<.01). SF-36 scale scores were compared between Cadaveric Liver Transplant recipients and Living Donor Liver Transplant recipients. Donor types of post LT did not influence HRQOL(p>0.05). 87% of the liver transplant recipients were satisfied to get LT. Satisfaction of post LT showed significantly greater HRQOL(p<0.001). Conclusion : SF-36 is found reliable and valid. This study indicates thet Donor Type did not influence HRQOL after LT. The information gained from this study will help us to better define expectations and the clinical course after liver transplantation to patients and their families.

일반적으로 간경변에 동반된 비장은 비대한 것으로 알려져 있다. 본 연구는 간경변을 보유한 환자의 복부 CT 영상을 이용하여 비장의 웨이브 패턴(wave patten)을 관찰하였는데 정상간을 보유한 사람의 복부 CT 영상과 차이가 있음을 발견하였다. 간경변을 가지고 있는 환자의 복부 CT 영상에서 비장은 왼쪽 측면에 깊은 웨이브 부분이 존재하였다. 정상간의 경우에도 왼쪽 측면에 웨이브가 존재하기도 하나 깊이가 깊지 않음을 알 수 있다. 그러므로, 간경변을 가진 비장의 웨이브 부분들의 면적의 합이 정상간을 가진 비장의 웨이브 면적보다 크다는 것을 알 수 있다. 나아가, 간경변을 보유한 영상에서 비장의 웨이브 부분을 추출하여 원형성(circularity)을 살펴보았을 때 정상간에 수반된 비장의 웨이브 부분보다 더 원형에 가깝다는 것을 알 수 있었다. 본 논문은 위와 같이 관찰된 원리를 바탕으로 복부 CT 영상에서 비장의 웨이브 패턴을 이용하여 비장 비대를 효과적으로 진단하는 새로운 방법을 제시한다. 이는 단순히 비장의 크기만을 이용하지 않고 비장의 형태 변화로써 국소적 비장 비대를 자동 판정해 낼 수 있음을 말해주는 것이다.

Three commercial strains bred in the US (Hubbard), Holland (Lohman), and Canada (Shaver) and Balady breed of chickens were orally infected with $10^6$ cfu of Salmonella gallinarum per chick. Chicks were compared for weight gain, feed intake, feed conversion ratio, mortality rate and contamination of the liver, spleen and intestine with Salmonella gallinarum on the day of slaughter. The Balady chicks had significantly the lowest mortality rate (p<0.01) and weight gain (p<0.001) and poorest feed conversion ratio (p<0.001). Salmonella gallinarum could be shed from the liver, spleen and intestine with alternative rates in all strains. Lohman was the most resistance over the other two commercial strains, while Hubbard had the highest susceptibility. The Balady chicks were the most resistance. However, they may serve as a possible reservoir of Salmonella gallinarum and it may play a role of spreading the infection to the commercial farms in Jordan.

300 MHz proton NMR spectra of human blood plasma were analyzed by deconvolution of spectrum, and we compared its results with Fossel's test in normal (15 cases), liver cancer (14 cases) , and other cancer (14 cases) groups. This analysis had enabled us to obtain dynamic characteristics of each individual lipoprotein. As a result of deconvolution method, the VLDL and chylomicron intensity level were found to be elevated in the patients with liver cancer. Moment ratio values of $CH_2$ resonance in the raw spectrum were found to be higher than the normal group for patients with, malignant tumors other than liver cancer. These differences between the three groups could not be found in the conventional Fossel's test. We could simulate plasma spectra by addition of spectra of individual lipoproteins through deconvolution method. Further clinical trials in larger populations and additional biochemical method may shed new light on many of clinical and biochemical interests for knowing characteristics about lipoprotein not separated from blood and the background of Fossel test.

In an effort to develop the biomarker for monitoring the contamination of xenoestrogen in the freshwater environment of Korea, reverse transcription-polymerasechain reaction (RT-PCR) analysis of vitellogenin (VTG) gene expression was optimized in Hearisarsus Iaseo, Based on the homology of the VTG cDNA sequences between the common carp and zebra fish, a set of PCR primers for VTG mRNA amplification for H; labo was designed. VTG mRNA level in livers from female and male fishes was analyzed by RT-PCR following single injection of 17 beta estradiol($E_2$ 10 mg $kg^{-1}$ B.W.). As an internal control, beta actin mRNA was amplified. One us of total liver RNA was subjected to RT-PCR. In female the amount of PCR productof VfC gradually increased in the range from 16 to 34 cycles of amplification. On the contrary, in control male, PCR product first detected at 32 cycles of amplification and linearly increased up to 40 cycles of amplification. In $E_2$ injected male liver, the VTC mRNA level was similar to that in the female. Taken together, this result suggests that liver of male H. labo expresses minute amount of VTG mRNA which are2-l6 equivalent of female and that induction of VTG mRNA occurs in male liver after estrogen treatment. In conclusion, the optimized protocol for RT-PCR analysis of VTG mRNA expression in liver of male H. labo will provide the environmental monitoring method for the xenoestrogen contamination in the rivers in Korea.

Background: The population in northeast Thailand continues to present with hepatobiliary abnormalities, particularly periductal fibrosis (PDF) which is the result of chronic infection with liver fluke (Opisthorchis viverini; OV) and may lead to the development of cholangiocarcinoma (CCA). Although the prevalence of OV infection has been decreased due to a liver fluke control program over decades, the prevalence of PDF remains high. This study aimed to investigate demographic factors associated with PDF risk based on ultrasonography (US) screening. Materials and Methods: This cross-sectional study is part of the Cholangiocarcinoma Screening and Care Program (CASCAP), a prospective cohort study. Multiple logistic regression was used for data analysis. Results: In 55,246 subjects, the overall prevalence of PDF was 33.0% (95%CI: 32.6 - 33.4). Males (33.9 %) were at higher risk for developing PDF than females (32.2 %) (ORcrude = 0.93; 95%CI: 0.89 - 0.96; p-value < 0.001). Factors associated with an increased PDF risk, in addition to OV infection, included old age (${\geq}70$ years) (ORadj = 1.28, 95% CI: 1.14 - 1.44, p < 0.001) and hepatitis B infection (ORadj = 1.31, 95% CI: 1.11 - 1.55, p = 0.001). In contrast, number of praziquantel treatments (> 2 times) (ORadj = 0.54, 95% CI: 0.47 - 0.63, p < 0.001) and diabetes mellitus (ORadj = 0.57, 95% CI: 0.49 - 0.65, p < 0.001) were significantly associated with a decreased PDF risk. Conclusions: Future US screening should closely examine older people and hepatitis B subjects for the purpose of PDF surveillance among high risk groups for CCA. However, the results of inverse associations require further investigation in order to confirm our findings.

Purpose: This study systematically evaluated the implications of advanced age on post-surgical outcomes following gastrectomy for gastric cancer using a national database. Materials and Methods: The 2011-2017 National Inpatient Sample was used to isolate patients who underwent gastrectomy for gastric cancer. From this, the population was stratified into those belonging to the younger age cohort (18-59 years), sexagenarians, septuagenarians, and octogenarians. The younger cohort and each advanced age category were compared in terms of the following endpoints: mortality following surgery, length of hospital stay, charges, and surgical complications. Results: This study included a total of 5,213 patients: 1,366 sexagenarians, 1,490 septuagenarians, 743 octogenarians, and 1,614 under 60 years of age. Between the younger cohort and sexagenarians, there was no difference in mortality (2.27 vs. 1.67%; P=0.30; odds ratio [OR], 1.36; 95% confidence interval [CI], 0.81-2.30), length of stay (11.0 vs. 11.1 days; P=0.86), or charges ($123,557 vs. $124,425; P=0.79). Compared to the younger cohort, septuagenarians had higher rates of in-hospital mortality (4.30% vs. 1.67%; P<0.01; OR, 2.64; 95% CI, 1.67-4.16), length of stay (12.1 vs. 11.1 days; P<0.01), and charges ($139,200 vs. $124,425; P<0.01). In the multivariate analysis, septuagenarians had higher mortality (P=0.01; adjusted odds ratio [aOR], 2.01; 95% CI, 1.18-3.43). Similarly, compared to the younger cohort, octogenarians had a higher rate of mortality (7.67% vs. 1.67%; P<0.001; OR, 4.88; 95% CI, 3.06-7.79), length of stay (12.3 vs. 11.1 days; P<0.01), and charges ($131,330 vs. $124,425; P<0.01). In the multivariate analysis, octogenarians had higher mortality (P<0.001; aOR, 4.03; 95% CI, 2.28-7.11). Conclusions: Advanced age (>70 years) is an independent risk factor for postoperative death in patients with gastric cancer undergoing gastrectomy.

The detoxifying properties of cruciferous vegetables components have been the subject of several recent investigations. Evidences from many biochemical and pharmacological studies indicated that higher consumption of cruciferous vegetables is associated with lower incidence of harmful actions such as hepatotoxicity and oxidative stress in animal and human populations. Recently, it has been reported that drug metabolizing and detoxifying enzyme activities were increased by cruciferous vegetable extract in which sinigrin is known to be a main active component, accounting for about 2 to 3 percents of total extract. The detoxifying effect of sinigrin has been well reported in several literatures. The metabolism of sinigrin in animal, however, has not been reported yet. That led us to study the metabolism of sinigrin in rat. Sinigrin is nown to be metabolized into three compounds, i.e., allyl isothiocyanate, glucose and potassium phosphate in cruciferous vegetables. Allyl isothiocyanate was formed in rat hepatic mitochondrial fraction in dose and incubation time dependent manner, that was confirmed by HPLC. Glucose formation was came up with results similar to that of allyl isothiocyanate. Three hours after i.p. administration of sinigrin to rat, allyl isothiocyanate appeared in rat liver, and five hours later it was detected in liver and blood. The above results suggested that sinigrin might be metabolized into allyl isothiocyanate, glucose and potassium phosphate in rat.

Angiocentric T-cell lymphoma is a rare form of peripheral T-cell lymphoma. The disease typically manifests clinically as an aggressive, progressively destructive disorder often with a fatal outcome. It is the aim of the present paper to derive further studies evaluating the effectiveness of Korean traditional medicine on angiocentric T-cell lymphoma with intra-abdominal metastasis. A patient with high fever, weight loss, night sweat and general weakness(B symptoms) was diagnosed as angiocentric T-cell lymphoma and chemotherapy was done more than 10 times. But the response to chemotherapy was poor, finally the lymphoma involved liver and spleen. The abdominal CT showed the hepatosplenomegaly, diffuse lymphoma of liver and spleen, massive ascites, minimal pleural effusion. Then the patient gave up the chemotherapy and only herb medications (Bohyunsoamtang-A,B) were administered. The ascites, high fever and hepatosplenomegaly gradually reduced to normal. He survived for 7 years after first diagnosis, which is much longer than average survival time in angiocentric T-cell lymphoma with B symptoms. This case may give us a possibility of that Korean traditional herb medications offer potential benefits for patients with angiocentric T-cell lymphoma, and more researches are needed.
