Recently, cases of Aloe vera induced-toxic hepatitis have been reported. However, the precise inflammatory effects of Aloe vera extract have not been clearly elucidated yet. In this study, the inflammatory effects and the mechanism of 70% ethanolic Aloe vera extract on liver were evaluated by in vitro assays using human hepatoma HepG2 cells. Cell viability was investigated using MTT assay at $0.001{\sim}100{\mu}g/mL$ of Aloe vera extract. To evaluate inflammatory effect of the Aloe vera extract, the secretion of pro-inflammatory cytokine Interleukin 8 (IL-8) and Macrophage colony-stimulating factor (M-CSF) were detected. Aloe vera extract did not induce cell death at concentrations of $0.001{\sim}100{\mu}g/mL$. However, Aloe vera extract significantly increased the IL-8 secretion by 15.7~25.8% and the M-CSF secretion by 36.6~61.5% at the same concentrations. These results indicate that Aloe vera extract shows an inflammation-related mild hepatotoxicity than a severe toxicity such as cell death and this hepatitis is mediated by the secretion of inflammatory cytokine IL-8 and M-CSF.

Ursodeoxycholic acid (UDCA) has long been used as an adjuvant or first choice of therapy for liver disease. Commonly, UDCA has been reported to play a role in improving hyperbilirubinemia and disorder of bromsulphalein. More commonly, UDCA has been used in reducing the rate of cholesterol level in bile juice that can cause cholesterol stone. The effects on the promotion of bile acid release that leads an excretion of toxic materials and wastes produced in liver cells as well as various arrays of liver disease such as hepatitis. Other than already reported in clinical use, immunosuppressive effect has been studied, especially in transplantation. In the study, we hypothesized that UDCA might have a certain role in anti-inflammation through a preventive effect of pro-inflammatory potentials in the brain macrophages, microglia. We found that the treatment of $200\;{\mu}g/ml$ UDCA effectively suppressed the pro-inflammatory mediators (i.e. nitric oxide and interleukin-$1{\beta}$) in rat microglia compared to comparators. Interestingly, RT-PCR analysis suggested that UDCA strongly attenuated the expression of $IL-1{\beta}$ that was comparable with cyclosporine A at 48 h incubation. Conclusively, we found that UDCA may playa cytoprotective role in microglial cells through direct or indirect pathways by scavenging a toxic compound or an anti-inflammatory effect, which are known as major causes of neurodegenerative diseases.

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.

Although primary application of radioisotope scanning technics to the liver has been of use in the detection of the intra-hepatic space occupying lesion from the normal functioning liver parenchyme, there has been on increasing awareness of its use in evalution of Liver function. In this study, the diseases of the liver were classified into group A,B,C and D by the liver scanning findings, conventional liver function tests and clinical findings. Following were the results: 1. The colloidal radiogold liver scan appeared normal in the group A, also the albumin in serum, alkaline phosphatase activity and prothrombin time were within normal levels in this group. 2. In the group B, there were acute hepatitis 24(48%), chronic hepatitis 5(10%), toxic hepatitis 3(6%), subacute hepatic necrosis 3(6%), typhoid liver 4(8%), hepatic tuberculosis 2(4%), diabetes mellitus 3(6%) and others 3(6%). In this group, SGOT and SGPT were increased predominantly as compared with group A, and the liver scan showed small amount of mottling of activity and faintly visualized spleen. 3. In the group C, there were postnecrotic liver cirrhosis 30(60%), Laennec cirrhosis 10(20%), cardiac cirrhosis 1(2%), cholangiocarcinoma 1(2%), chronic active hepatitis 6(12%), hepatic milliary tuberculosis 1(2%) and gall bladder cancer 1(2%). In this group, the albumin in serum and prothrombin time were lowered significantly and the liver scan showed severe mottling of activity with extra-hepatic uptake in the spleen and bone marrow along the vertebral column. 4. In the group D, there were primary hepatoma 26(52%), hepatoma with liver cirrhosis 7(14%), metastatic liver cancer 5(10%), liver abscess 10(20%), multiple liver cyst 1(2%) and cystic duct adenoma 1(2%), In this group, the alkaline phosphatase activity was elevated with single or multiple intrahepatic space occupying lesion in the radiogold colloid liver scan.

Drug-induced liver injury (DILI) is a common cause of acute hepatitis. Regarding the risk of DILI from herbal preparations, there are controversial issues such as exaggerated reports straying far from the truth and lack of discrimination between herbal drugs and folk remedies or food supplements. This study reported one case of a patient with DILI caused by Smilacis Chinae Radix and cured in an Oriental hospital. Smilacis Chinae Radix has been used as an anti-inflammatory, anti-microbial, detoxification and anticancer compound, as a folk remedy. This report would provide helpful information for management of DILI by folk remedies or herbal drugs.

We have experienced three cases of congenital bronchoesophageal fistula which is rare and usually has an insidious clinical course. The patients included a thirty year old man and thirty six, thirty eight year old women respectively. Bronchiectatsis was found in all three cases, and bronchoesophageal fistula was found in one case preoperatively by esophagography and esophagoscopy, and other two cases operative field. The fistula was found between right lower esophagus and right lower lobe in all cases and esophageal diverticulum in one case. So they belonged to type I[1 case , II[2 cases of Braimbridge and Keith`s classification of congenital bronchoesophageal fistula . The fistulectomy was performed in all cases and concomitant lobectomy [2 cases and bilobectomy [1 case were done. There were toxic hepatitis in two cases and prolonged air leakage in one case postoperatively. They were discharged on recovered state and have continued to do well.

Purpose: Several risk factors related with chronic complications and mortality related with liver injury of mushroom poisoning were reported. But, there were few reports about the long term outcomes. The aim was to evaluate the long term clinical outcomes in mushroom poisoning regarding the risk factors. Methods: Clinical data were reviewed and outcomes were evaluated with medical records and/or telephone interviews. The patients who had one or more risk factors such as markedly elevated aspartate aminotransferase (AST) or alanine aminotransferase (ALT), prolonged prothrombin time (PT) were classified into high risk group. Patients had no risk factor classified into low risk group. Results: From June 1989 to December 2003, nineteen mushroom poisoning patients admitted to Asan Medical Center, seven were male, and mean age was $58\pm9$ years old. All the patients accidentally ingested and the interval from ingestion to symptom onset was $9\pm4$ hours. There were four patients in high risk group, and fifteen in low risk group. In high risk group, peak AST was $2,263.3\pm1,303.0IU/L$most prolonged PT was $38.0\pm27.4\%$, and stuporous mental status was shown in one patient. In low risk group, laboratory values returned to the normal values but histological evaluation revealed specific features of toxic hepatitis on sixth hospital day. Chronic complications such as persistent or chronic hepatitis, mortality was not occurred during follow up period (from 10 months to 16 years) in both groups. Conclusion: Although the number of patients were small, there were no chronic complications or mortality related with liver injury after mushroom poisoning regardless risk factors of chronic complications and mortality.

In order to assess the diagnostic aid of serum gammaglutamyl transpeptidase values in hepatitis, obstructive jaundice and pancreatitis, four groups of 14 health dogs were subjected to the gastric intubatin of $CCl_4$(1.5ml/kg of body weight), the ligation of common bile duct, the ligation of pancreatic ducts and the injection of chloroform(0.2ml/kg of body weight) in the parenchyma of the pancreas. Some serum enzymes serum glutamic pyruvic transaminase(SGPT), serum glutamic oxalacetic transaminase(SGOT), total bilirubin, amylase and lipase known to be indicative of hepatic and pancreatic diseases were monitored. In comparision of these enzymes, gamma-glutamyl transpeptidase(GGTP) valuers were determined in these dogs before and after the experimental procedures. The results were summarized as follows: 1. In $CCl_4$ intoxication gorup, there were no significant changes in serum GGTP activities(mean: 6.0~14.6 IU/L). 2. In bile duct ligation group, serum GGTP activities shelved marked increases, beginning at postsurgical day 1 and rose the highest mean value(342.7 IU/L) on day 12. Then the activities never approached to the base-line values. 3. After the ligation of pancreatic ducts and the injection of chloroform in the pancreas, serum GGTP activities did not rise throughout the experiment. 4. SGPT:GGTP ratio did not increase in bile duct ligation group, but increase markedly in $ccl_4$ intoxication group. 5. The results indicated that serum GGTP values or SGPT:GGTP ratio could provide valuable indicators for differential diagnosis between hepatobiliary obstruction and hepatocellular disease.

Objective: To investigate the possibility of hepatotoxicity by supplemental foods or folk herbs such as Salvia Plebeia R. Br. Methods: A hospitalized male patient with alcoholic liver disease and electrolyte imbalance had recovered, and then followed by rapid hepatic serum enzymes after taking S. Plebeia. This study monitored the clinical outcome and biochemical parameters. Result: A 58-year male had drunk frequently, which led to alcoholic steatohepatitis and hospitalization. Two weeks after his discharge from hospital, he felt nausea, dizziness, and mild difficulties in speech and walking, resulting in re-hospitalization at the Korean Medical Hospital. The symptoms disappeared on correction of the electrolyte imbalance suspected to have been caused by severe sweating while working in the outdoors, and the patient was discharged. During treatment and monitoring of his health as an outpatient, the serum hepatic enzyme rapidly elevated approximately 10-fold in hepatic enzymes; the enzyme levels fluctuated according to whether or not he was taking the boiled water of S. Plebeia. The RUCAM score was 12, which met the criteria for toxic hepatitis by S. Plebeia. His general condition and abnormal hepatic enzymes recovered with cessation of S. Plebeia and administration of Chungganplus syrup (CGX). Conclusion: This study reports the hepatotoxic risk of Salvia Plebeia, which is commonly used as a folk remedy in Korea.
