  • The acute and subacute toxicity of water soluble dimethyl dimethoxy biphenylate derivative (new DDB), hepatitis therapeutics, were investigated in SD rats. In the acute toxicity study, body weights and clinical signs were observed for 7 days after the intravenous injection of new DDB at doses of 140, 182, 236, 307 and 400 mg/kg(r=1.3). Death. Severe convulsion, tremor and decrease motor activity were observed in almost treated groups (except the 140 mg/kg treated group). Changes of body weight in treated groups were not significantly different from control group. Autopsy of survived animals revealed no abnormal gross findings related to new DDB. As a results, the $LD_{50}$ values of new DDB were 244.1 mg/kg for male and 232.5 mg/kg for female. In subacute toxicity study, body weights and clinical signs were observed after intravenous injection of new DDB at doses of 57, 75 and 100 mg/kg/day for 28 days. Death, decrease motor activity and tremor were observed above 75 mg/kg treated groups. Statistically significant changes were observed in hematological and biochemical parameters of new DDB-treated groups; however, these changes were within normal range and had no relationship with dosage. Several abnormal findings were observed in microscopic examination of tissue; however, these findings were not caused by new DDB but environmental factor. The no toxic dose level of new DDB were estimated to be 57 mg/kg/day in this study.

  • Severe acute alcoholic liver disease (SAAH) unresponsive to medical therapy shows one-year-mortality rates of up to 90%. Most transplant centers request six months of alcohol abstinence prior to transplantation, the so-called "6-month rule." This regulation is not based on strong evidence, repeatedly making it a topic of controversial debates. The majority of patients with SAAH will die before fulfilling the 6-month rule. Therefore, liver transplantation (LT) protocols are becoming more flexible towards the rigid abstinence regulation, especially concerning SAAH patients. We conducted a literature review regarding LT in SAAH and its outcomes, including post-transplant mortality and recidivism. We studied available data on PubMed from 2011 and onwards whilst including articles dealing with genetic components, medical therapy and historic snapshots of alcoholism. Emerging studies recommend LT in SAAH not responding to medical therapies even without realizing the required abstinence period, since the majority of these patients would die within 6 months. SAAH without response to medical therapy has one-year-mortality rates of up to 90%. The 6-month rule is not based on strong evidence and is repeatedly a topic of controversial debates. There is genetic linkage to alcoholism and medical therapy is not as effective as estimated, yet. The 6-months-regulation has not shown to evidently decrease the risk of recidivism post-LT, which is a lifesaving treatment in SAAH patients. Insisting on rigid sobriety rules results in excluding patients with a low risk of recidivism from being transplanted. Moreover, the genetic linkage of alcoholism must be recognized.

  • This study aimed to investigate the protective effect of dandelion water extract (DWE) on liver injury induced by D-galactosamine (GalN) in Sprague-Dawley rats. Fifty rats were divided into 5 groups; normal control (C), DWE-control (DWE-C: saline injection after feeding 3% DWE diet), GalN-control (GalN-C: GalN injection after normal diet), DWE I (GalN injection after feeding 1.5% DWE diet), and DWE II (GalN injection after feeding 3% DWE diet). After 2 weeks, the acute hepatitis was induced by GalN (650 mg/kg, i.p.) and 24 hrs later, all rats were sacrificed. The DWE supplement ameliorated the serum alanine and aspartate aminotransferase (AST, ALT) as well as alkaline phosphatase (ALP) and tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$. Hepatic antioxidative enzyme activities, such as catalase, GSH peroxidase, GSH reductase, and Mn-superoxide dismutase (SOD) were slightly or significantly elevated by the treatment of DWE. Moreover, the histological examination corresponded with these biochemical observations. According to these findings, dandelion could be used as a potential therapeutic material for treating chemically induced acute hepatitis.

  • Objective: The objective of our present study was to assess the efficacy of carcinoembryonic antigen (CEA) for differentiating and diagnosis of pancreatic and liver diseases in Pokhara valley. Materials and methods: A hospital based retrospective study was carried out using data retrieved from the register maintained in the Department of Biochemistry of the Manipal Teaching Hospital, Pokhara, Nepal between 1st January, 2011 and 31st October, 2011. Estimation of CEA was performed by ELISA reader for all cases. Approval for the study was obtained from the institutional research ethical committee. Results: Of the 771 subjects, 208 (27%), 60(7.8%), 240(31.1%), 54(7.0%), 75(9.7%), 59(7.7%), 75(9.7%) cases were of active chronic hepatitis, cryptogenic cirrhosis, alcoholic cirrhosis, primary biliary cirrhosis, hepatoma, acute or chronic pancreatitis, carcinoma of pancreas respectively. The majority of cases (104) of active chronic hepatitis had CEA levels <5ng/ml(50%). CEA levels were found to be increased in cases of alcoholic cirrhosis with maximum number of cases (106) in range of 10 to 20 ng/ml (44%). There were no cases having more than 20ng/ml of CEA in primary biliary cirrhosis and acute or chronic pancreatitis. In cases of pancreatic cancer, maximum number of cases (35) were having CEA >20ng/ml(47%). Conclusion: High levels of CEA are associated with advanced stage of disease. CEA can thus provide an important improvement in the diagnosis by differentiating pancreatic cancer especially from chronic pancreatitis when there is a high suspicion of malignancy. Increased CEA levels may also signify progression from benign to malignant transformation in the liver.

  • Currently, drug-induced liver injury (DILl) has been reported to be common cause of acute hepatitis, and oriental medicine and folk remedies are no exception. However, because many studies about DILl have been reported by western medical society. they has taken the initiative of DILl not only for western drugs but also herbs. So, academia of oriental medicine should make an effort to progress herb-related DILl studies. We describe a patient of acute liver injury which had been caused by comfrey, albizzia julibrissin, ulmus davidiana var. japonica, red ginseng. We hope that this report helps for studying the diagnosis and management of herb-derived DILl. and for establishing a standard of oriental therapy to DILL.

  • Tsutstugamushi disease is a major febrile disease that generally occurs in the fall in Korea with hemorrhagic fever with renal syndrome and leptospirosis. This disease is often accompanied by interstitial pneumonia, acute renal failure and liver failure. The causative agent, namely Orientia tsutsugamushi, is transmitted to humans through the bite of a laval trombiculid mite, which is commonly known as a chigger. A 78 year old man was admitted in October 2004 with intractable fever and a drowsy mentality. Two weeks earlier, he visited a private clinic complaining of a simple skin rash. He was treated with antihistamine and steroid, but his symptoms were aggravated and he was referred to our hospital. His physical examination and laboratory findings showed a septic shock status. The maculopapular rash had spread over his face, chest, abdomen and extremities. Eschar was observed in lower back area but it was too difficult to distinguish it from other skin rashes. His chest X-ray appeared as diffuse nodular patchy consolidations in the bilateral lung parenchyme. He was treated with a mechanical ventilator and doxycycline under th suspicion of Tsutstugamushi disease. However, he suffered multiorgan failure accompanied by acute respiratory distress syndrome, acute renal failure and acute hepatitis. He was treated in the intensive care unit for approximately 12 weeks and his general condition was recovered.
