Alcoholic and nonalcoholic steaohepatitis is a leading form of chronic liver disease with few biomakers ad treatment options currently available. a progressive disease of NAFLD may lead to fibrosis, cirrhosis, and hepatocellular carcinoma. Recently, we extracted HIMH0021, which is an active flavonoid component in the Acer tegmentosum extract, has been shown to protect against liver damage caused by hepatic dysfunction. Therefore, in this study, we aimed to investigate whether HIMH0021 could regulate steatohepatitis and liver fibrosis during alcoholic or nonalcoholic metabolic process. HIMH0021, which was isolated from the active methanol extract of A. tegmentosum, inhibited alcohol-induced steatosis and attenuated the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) during hepatocellular alcohol metabolism, both of which promote lipogenesis as well as liver inflammation. Treatment with HIMH0021 conferred protection against lipogenesis and liver injury, inhibited the expression of cytochrome P4502E1, and increased serum adiponectin levels in the mice subjected to chronic-plus-binge feeding. Furthermore, in hepatocytes, HIMH0021 activated fatty acid oxidation by activating pAMPK, which comprises pACC and CPT1a. These findings suggested that HIMH0021 could be used to target a TNFα-related pathway for treating patients with alcoholic hepatitis.

직접적인 근거를 제시하기는 힘드나 정신장애에서 자가면역적 요소가 병인적으로 중요하다는 단편적인 보고들이 있다. 특히 바이러스 감염은 정신장애를 유발하거나 나중에 정신장애에 대한 소지를 증가시킬 가능성이 높다. 저자들은 최근에 많은 관심을 끌고 있는 C형 간염 항체(이하 anti-HCV)의 양성율이 자가면역적 관점 및 수혈 외에도 성행위 또는 약물의 존자에서 많다는 전파경로상의 특정 때문에 정신과 환자에서 일반 인구군보다 높을 것으로 추정되어 이를 확인해 보고자 본 연구를 시행하였다. 1992년 12월 초부터 1994년 5월 말까지 정신과에 입원한 환자 중에서 무작위로 효소면역측정법 (Abbott HCV EIA kit) 에 의해서 혈청내 anti-HCV를 검사하였으며, anti-HCV 양성 환자와 anti-HCV 음성인 환자를 구분하여 여러 변인별로 비교 분석하였다. 정신과 입원환자 113명중 12명(10.6%) 에서 anti-HCV 양성이었다. anti-HCV 양성자중 간기능검사상 이상이 있는 경우가 50.0% 로서 이중 83.0%는 주정 의존자였으며, 간기능검사상 정상인 환자의 83.3%는 비주정의존자였다. 정신과 진단별 anti-HCV 양성율은 주정의존 환자의 22.2%, 정신증 환자의 2.3% (주로 양극성장애), 신경증(불안장애, 적응장애)환자의 22.2%에서 anti-HCV 양성이 나타났다. 연령, 출생계절, 임파구(%), 간기능 등 변인에 대한 유의한 상관성은 관찰되지 않았다. 결론적으로 정신과 입원환자는 정상 대조군 (3.0%)에 비해 최소한 3.5배 이상 anti-HCV 양성율이 높으므로 (P<0.05), 이에 대한 주의를 환기시킬 필요가 있다.

This study was performed to investigate the effect of the extracts from Injinoryng-San on liver injury patients induced by alcohol. Injinoryung-San was recorded the drug for jaundice at Hwang-Je-Nae-Kyung. Twenty-seven patients who have intaked alcohol above 40 g, every day, 5 years, twenty-seventy ages were selected. After take a written consent, we divide them into experimental groups and control groups by double blind test. Each groups was evaluated every 2 weeks(2,4,6 weeks). After 2 weeks, Injinoryung-San groups significantly decreased GGT in comparison with control groups(p<0.05). After 4 weeks, Injinoryung-San groups significantly decreased MCV, GGT in comparison with control groups(p<0,05). After 6 weeks, Injinoryung-San groups significantly decreased MCV in comparison with control groups(p<0.05). Reviewing these experimental results, it appears that extracts of Injinoryung-San have pharmaceutical efficacy in GGT, MCV on liver injury patients induced by alcohol. But it has not efficacy in AST, ALT. According to drinking alcohol has becomes social problems, we should effort to make efficacious oriental medicines on alcoholic hepatitis.

We examined whether the abnormal EEG state by NMDA receptor blocker MK-801 can be reversed by typical and atypical antipsychotics differentially by comparing their spectral profiles after drug treatment in rats. The spectral profiles produced by typical antipsychotics chlorpromazine (5 mg/kg, i.p.) and haloperidol (0.5 mg/kg, i.p.) were differ from that by atypical antipsychotic clozapine (5 mg/kg, i.p.) in the rats treated with or without MK-801 treatment (0.2 mg/kg, i.p.) which produce behavioral abnormalities like hyperlocomotion and stereotypy. The dissimilarity between the states produced by antipsychotics and the control state was examined with the distance of the location of the canonical variables calculated by stepwise discriminant analysis with the relative band powers as input variables. Although clozapine produced more different state from normal state than typical antipsychotics, clozapine could reverse the abnormal schizophrenic state induced by MK-801 to the state closer to the normal state than the typical antipsychotics. The results suggest that atypical anesthetic can reverse the abnormal schizophrenic state with negative symptom to the normal state better than typical antipsychotic. The results indicate that the multivariate discriminant analysis using the spectral parameters can help differentiate the antipsychotics with different actions.

간질이나 신경성 통증 등으로 많이 쓰이고 있는 phenytoin, carbamazepine, 그리고 phenobarbital등의 항경련제는 피부, 임파절, 간 그리고 폐 등을 포함하는 전신적인 반응을 동반하는 anticonvulsant hyper-sensitivity syndrome을 유발할 수 있다. 그 임상양상은 환자에 따라 매우 다양하며 드물게 치명적인 경과를 가질 수 있어 의심되는 경우에는 약제의 사용중단이 가장 중요한 것으로 알려져 있다. 저자들은 carbamazepine을 투여 후 피부병변, 고열, 호산구증다증, 임파절종대와 호산구성폐렴을 보였던 환자를 anticonvulsant hypersensitivity syndorme으로 진단하고 원인약제 투여중단 후, 증상, 혈액학적 이상소견 그리고 방사선학적 이상소견의 호전이 관찰되었던 1예을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Background: Human papillomavirus (HPV) is a very common sexually transmitted disease affecting both men and women and is responsible for different ano-genital cancers in either sex. Co-existing sexually transmitted infections (STI) including HIV have been considered as important co-factors for carcinogenesis induced by HPV. The purpose of this study was to determine the prevalence of any HPV, HPV 16 and HPV 18 and also concomitant STIs among female sex workers (FSW), men having sex with men (MSM) and injectable drug users (IDU). Material and Method: This cross-sectional study was conducted among 45 FSWs, 26 MSMs and 58 IDUs who attended the STI or de-addiction clinics. Genital scrape samples collected from glans penis and coronal sulcus in males and cervical squamo-columnar junction in females were tested for HPV DNA by PCR using HPV L1 consensus primer. Type specific PCR to detect HPV 16 and 18 was done on the samples positive on consensus PCR. All participants were tested for associated STIs including HIV and hepatitis B and cervical cytology was done on all females. Results: Among the FSWs, HPV was detected in 73.3% and HPV 16 and 18 was detected in 25.7%. Though the HPV prevalence was similarly high among MSMs (69.2%) and IDUs (72.4%), the prevalence of HPV 16 and 18 was much lower in these groups compared to the FSWs. Prevalence of cervico-vaginal infection with Trichomonas vaginalis and syphilis was significantly higher in the HPV positive women compared to the HPV negative women. There was no statistically significant difference in the prevalence of other STIs among HPV positive and negative women and men. Conclusion: HPV infection is highly prevalent among FSW, MSM and IDUs. Trichomonas vaginalis infection is more frequent in HPV positive women.

Purpose: Gallbladder (GB) wall thickening can be found in various conditions unrelated to intrinsic GB disease. We investigated the predisposing etiologies and the outcome of acalculous GB wall thickening in children. Methods: We retrospectively analyzed 67 children with acalculous GB wall thickening who had visited our institute from June 2010 to June 2013. GB wall thickening was defined as a GB wall diameter > 3.5 mm on abdominal ultrasound examination or computed tomography. Underlying diseases associated with GB wall thickening, treatment, and outcomes were studied. Results: There were 36 boys and 31 girls (mean age, $8.5{\pm}4.8years$ [range, 7 months-16 years]). Systemic infection in 24 patients (35.8%), acute hepatitis in 18 (26.9%), systemic disease in 11 (16.4%), hemophagocytic lymphohistiocytosis in 4 (6.0%), acute pancreatitis in 3 (4.5%), and specific liver disease in 3 (4.5%) predisposed patients to GB wall thickening. Systemic infections were caused by bacteria in 10 patients (41.7%), viruses in 5 patients (20.8%), and fungi in 2 patients (8.3%). Systemic diseases observed were systemic lupus erythematosus in 2, drug-induced hypersensitivity in 2, congestive heart failure in 2, renal disorder in 2. Sixty-one patients (91.0%) received symptomatic treatments or treatment for underlying diseases. Five patients (7.5%) died from underlying diseases. Cholecystectomy was performed in 3 patients during treatment of the underlying disease. Conclusion: A wide range of extracholecystic conditions cause diffuse GB wall thickening that resolves spontaneously or with treatment of underlying diseases. Surgical treatments should be avoided if there are no definite clinical manifestations of cholecystitis.

We report on a case of severe hepatotoxicity in a 52-year-old male with multiple myeloma (MM) who had received bortezomib therapy. At patient presentation, liver enzymes were normal, but started to markedly increase 3 days after the patient's second dose of bortezomib was administered, when free kappa light chains were noticeably reduced in the serum. After discontinuation of bortezomib, liver enzymes recovered gradually to baseline. Then, the patient was started on a thalidomide-containing regimen, which he was able to tolerate well. The patient achieved complete remission prior to autologous stem cell transplantation (ASCT). The patient underwent ASCT without occurrence of further liver toxicity.

Standard combination chemotherapy including isoniazid, rifampin, pyrazinamide, and ethambutol is very effective against tuberculosis. But, these medicines can cause hepatotoxicity which is the main reason for treatment interruption or change in drug regimen. In order to identify risk factors associated with hepatotoxcity in Koreans and assess elevated baseline LFTs' contributions to hepatotoxicity, a retrospective case control study was performed. The medical records of 277 patients who diagnosed with tuberculosis at a community hospital from January 1st, 2007 to June 30th, 2010 were reviewed. Patients were categorized into 3 groups (non toxic group, patients without increase in LFT levels; mild to moderate hepatotoxic group and severe hepatotoxic group). And the correlation between risk factors and hepatotoxicity was analyzed by using SPSS program. The overall incidence of hepatotoxicity was 18% and 8.7% of patients developed severe toxicity. Patients in the severe toxic group had the longest treatment period among the three groups. In 75% of severe toxic group, hepatotoxicity occurred within 18.3 days after starting medication. Hypoalbuminemia (serum albumin <3 g/dl) was a significant risk factor for development of severe toxicity. Elevated baseline transaminase (except ALT), total bilirubin, and preexisting hepatitis were also risk factors which were more than twice as likely to increase risk of severe hepatotoxicity (p>0.05). In conclusion, hypoalbuminemia (serum albumin level <3 g/dl) was a significant risk factor for anti-tuberculosis druginduced severe toxicity. Therefore, before starting antituberculosis chemotherapy, serum albumin level should be assessed at baseline. In high-risk patients (hypoalbuminemia, elevated LFTs) for hepatotoxicty, liver function should be closely monitored up to at least 21 days after taking medication.
