Psoralens are metabolized in the liver and thus can produce liver damage in laboratory animals when given in excessive doses. However, in humans, reports of the effects of psoralens on liver functions during photochemotherapy have been contradictory. We studied 311 patients t o observe the effects of various phototoxic drugs: 8-methoxypsoralen (8-MOP), 5-methoxypsoralen (5-MOP), 4,5,8-trimethylpsoralen (TMP)-on liver function during photochemotherapy. Of the 311 patients, only seven had transient elevations of transaminases. Incidence of hepatotoxicity of 8-MOP, TMP and 5-MOP showed 0.6%, 6% and 3%, respectively. Although the effects of psoralens on liver functions during photochemotherapy have been contradictory in humans and there have been few cases showing transient elevated values of liver transaminases during photochemotherapy, it is advisable to obtain serial liver function tests before and during photochemotherapy.

Introduction: ALT/AST enzymes are present inside the cells. AST is found in cardiac and skeletal muscle and red blood cells but the ALT is checked mainly in the liver. In general, the rise of these two indicators shows liver damage. The usual measurements of these enzymes are used in liver function tests, but the levels of AST and ALT do not always reflect liver function. Method and Cases: 17 cases of liver dysfunction transiently were evaluated clinically, biochemically, and imaging study of sonogram in pediatric in-patients for 3 years. Result: Most common causes of transient liver dysfunction were infection, especially viral gastroenteritis, and bacterial infection interfering oral food intake. More often occurred in the children who have infant hyperbilirubinemia, positive history of mitochondrial dysfunction or hypoglycemia. Fasting study in one case of hypoglycemia patient showed reversible liver dysfunction during fasting over 20 hours fasting. Discussion: A significant increase in AST and ALT with normal bilirubin can be observed in clinically healthy people during blunt trauma, viral infection, severe pain, metabolic syndrome, fasting or accidental health screening.

Objectives: This case report describes a patient who had suffered a stroke and who was treated for a long period with herbal medicine in combination with a Western medicine. Methods: Changes in liver function and renal function laboratory tests were measured while the patient took herbal medicine during the 1190 days of hospitalization. Results: During the hospitalization period, the liver function test (LFT) levels were elevated two fold, but after taking the herbal medicine, the LFT levels were stabilized and have remained stable since. Conclusions: The high risk of prescribing herbal medicine by an unlicensed person and the possibility of long-term herbal medicine usage for stabilizing liver function test were shown.

동일한 처방을 투여해도 환자에 따라 정상반응을 보이는 경우가 있고 과민반응을 보이는 경우가 있다. 이 경우는 한약 자체의 문제라기보다는 특정 약물이 환자에 몸속에서 과민하게 반응하는 것으로 보인다. 만약 특정 약물에 과민 반응이 있다면 이것은 한의사의 책임이라기보다는 환자의 특이한 신체 조건에 기인한다라는 것을 환자에게 충분히 인지시킨후, 과민반응을 유발하는 약물을 제거하고 처방할 필요가 있다고 본다. 또한 일부 환자에게 과민반응을 일으키는 약물이 어느 정도가 있고, 얼마 동안 복용해야 과민반응을 보이는지에 관한 부분이 좀 더 정리가 된다면 한약의 장기 복용시 간손상에 관한 부분이 크게 문제가 되지 않을 것으로 본다. 이것은 한약이 절대로 부작용이 없는 약이 아니라 특정한 사람에게는 부작용을 일으킬 수 있다는 것을 환자에게 각인시키는 계기가 될 것이며, 이는 한약을 한약의 전문가인 한의사만 다룰 수 있도록 해야 하는 근거가 되는 한 예로 작용할 것으로 보인다. 또한 한의사도 간수치 측정 기기와 같은 이화학적 의료 기기에 대한 사용권을 확보하여 수가를 받음으로서 약물의 안정성과 환자로부터 신뢰를 얻는데 노력을 경주하여야 할 것으로 보인다.

Workers' periodic health examination is the main tools used to manage the health problems of most workers in Korea. The most common health problem found in workers' periodic health examination is liver disorder. Liver disorder is also one of the most common health problems in general population and one of the leading causes of mortality in adult population. Regulation proposed by government (No. 207, Ministry of Labor, 1992) defines the criteria for selection of workers with the liver dysfunction for further evaluative examination and the examination items used for diagnosis of the workers with liver dysfunction. This study was designed to evaluate the proficiency of each examination items presently defined in Regulation and propose the optimal examination items for detection of the liver disorders found by workers' periodic health examination. Study subjects are 186 workers with abnormal liver function tests in screening examination of workers' periodic health examination. Questionnaire survey including past history of liver disorder, drinking history, height and weight was done. Physical examination by physician, routine test items defined by Regulation (SGOT, SGPT, $\gamma$-GTP, protein, albumin, total and direct bilirubin, alkaline phosphatase, $\alpha$-feto protein, HBsAg and anti-HBs), anti-HCV antibody test and liver ultrasonography were done. Results are as follows; 1. Result of evaluative examination utilizing only the items defined in Regulation was; There were 75 workers with suspected live. disorder(40.3%), 63 with no liver dysfunction (33.9%), 13 with suspected hepatitis B(7.0%), 10 workers with hepatitis B(5.4%), 10 workers with hepatitis B carrier state(5.4%), 10 with alcoholic liver disorders(5.4%), 5 with fatty liver(2.7%). When alternative diagnostic criteria applying additional examination items (drinking history, body mass index, anti-HCV antibody and ultrasonography) diagnosability of liver disorder was increased. When all four items were included, final results were; 23 workers (17.8%) with hepatitis B (10 carriers, 13 suspects and 10 hepatitis B), 10 (5.4%) with hepatitis C(4 carriers, 5 suspects and 1 hepatitis C), 13(7.0%) with alcoholic liver disorder, 45(24.2%) with fatty liver (40 suspects, 5 fatty liver), 410%) with suspected liver disorders and 44 (23.7%) with normal liver. 2. Of examination items defined by Regulation, only SGOT, SGPT, $\gamma$-GTP and HBsAg were significantly different in abnormal rate and mean value, and all other laboratory findings did not showed significant difference between two groups. Drinking history, body mass index and anti-HCV antibody test which are the items that authors included in this study, also showed significant difference between two groups. Utilization of body mass index (BMI) for abnormal liver function group in diagnosis of fatty liver had high specificity (97.6%) but sensitivity (22.3%) was low. Therefore we suggest that SGOT, SGPT, $\gamma$-GTP, HBsAg, alcohol drinking history, BMI and anti-HCV Ab were useful for diagnosis of liver disorders among worker's periodic health examination.

Hepatocellular carcinoma (HCC) is the fi fth most common malignancy in the world and complicates liver cirrhosis related to hepatitis C virus (HCV) in many cases. We evaluated the therapeutic effect of Korean red ginseng extract (KGE) in patients with chronic liver diseases. Thirty male and female patients with HCC and another thirty with liver cirrhosis were included. Each category was divided into two groups; the first was used as control group, and received medical therapy only and the second group received the medical therapy supplemented with KGE capsules. The treated group with HCC received three KGE capsules/day (900 mg) while the treated group with HCV received two KGE capsules/day (600 mg) for 11 weeks along with their medical therapy. All patients were subjected to clinical examination and laboratory investigations, including liver function tests (at baseline, after 6 weeks of treatment and at the end of the study) and abdominal ultrasonography. Patients showing focal hepatic lesions were subjected to triphasic spiral abdominal computerized tomography and alpha-fetoprotein (AFP). HCV RNA was determined quantitatively by Roche for patients in the HCV group. Results showed that the medical therapy alone failed to normalize the liver enzymes or decrease the virus concentration. KGE administration induced a significant improvement in liver function tests, decreased the tumor marker (AFP) levels, and decreased the viral titers in HCV patients. Thus, KGE demonstrated powerful therapeutic effects against HCV and liver cancer.

Purpose: This study was conducted to investigate the effect of freeze-dried Gastrodiae rhizoma powder (GR) on the liver function and alcohol metabolism in alcohol treated rats. Methods: The rats were administered various concentrations of GR (100 mg, 200 mg, 300 mg/kg B.W.) for 3 days 1 hour before 50% (v/v) ethanol (3 g/kg B.W.) administration. Two tests focusing on liver function and alcohol metabolism in acute alcohol treatment were carried out. Results: Glutamic oxaloacetic transaminase activity was significantly increased by alcohol treatment, and was decreased by 100 mg GR administration. Acute ethanol treatment led to significant increase in alcohol and acetaldehyde levels of serum and liver. However, 100 mg GR administration led to a significant reduction in increased alcohol level in the serum with decreased alcohol dehydrogenase (ADH) activity and increased acetaldehyde level in liver was significantly reduced by three levels. Conclusion: These results suggest that GR can be effective in enhancing liver function and alcohol metabolism in the alcohol-treated rats. Studies on the appropriate dosage of GR should further be developed to treat alcohol detoxification and stimulate liver function.

Liver function test is one of the most common tests for diagnosis and follow-up of patients and for heal th screening. Automatic interpretation and suggestions on the diagnostic possibilities contribute to shorten the interpretation time of the test results and help to provide qualified health care. Fuzzy logic has been recently introduced and being spread for these purposes. The present study aims at model Ins the foray rule-based laboratory diagnosis system. The fuzzy rule-based laboratory diagnosis system was applied to the diagnosis regarding liver function test. The system was evaluated by comparing with the stepwise multivariate discriminant function analysis, which showed similar results, and the overall accuracy of the fuzzy diagnosis system was about 80%.

방사선이 간 담도계에 미치는 영향을 검토하기 위하여 선형가속장치에 의한 4MV X선 10, 15 및 20Gy를 흰쥐의 간 일부에 각각 조사한 후 1, 2, 4 및 8주에 간 담도계 손상의 지표로 이용 되고 있는 혈중 alkaline phosphatase 및 bilirubin의 함량을 측정 검토한 결과 먼저 alkaline phosphatase의 활성은 전 조사선량군에서 상승경향을 나타내었으며, 특히 20 Gy 8주군에서 현저한 상승을 나타내었고, 혈중 bilirubin의 함량도 시간 경과와 함께 상승경향을 나타내었으며, 20 Gy 8주군은 유의하게 상승하였다. 이상의 실험 성적을 종합해 볼때 방사선 조사로 인한 간 담도계의 장해는 조사된 선량에 따라 10 및 15 Gy군에서는 기간 경과와 함께 점차 회복되는 경향이었으나, 20 Gy군에서는 오히려 증가 된 것으로 보아 부분조사에서도 20 Gy가 한계선량임을 확인할 수 있었으며, 방사선치료시 간의 일부가 조사야에 포함되지 않도록하는 주의가 필요하다고 생각된다.
