This study is concerned with assessment of diethylnitrosamine(DEN) induced liver cell carcinogenesis by measurement of changes preceding the development of neoplasms. Therefore, it was undertaken to investigate the changes of liver-specific enzyme activities in rats (Sprague-Dawley) by ad libitum feeding of DEN. And also, as another objective index in urine, the level of urinary biopterin was measured by high performance liquid chromatography(HPLC) method. The results were as follows ; 1. Minor behavioral change, brittleness of hair and decreased amount of water and diet intake were observed in rats 7 weeks after DEN administration. 2. The body and liver weights were significantly(p<0.05) decreased in rats 11 weeks after DEN administration. 3. The ratio of liver weight to body weight was rather stable and not significantly decreased in the all treatment groups. 4. The liver specific enzyme activities(AST, ALT,$\gamma$-GTP) were significantly(p<0.05) increased in all treatment groups compared to control group. 5. Compared to normal level, urine biopterin level was significantly (p<0.05) increased in all treatment groups(p<0.05). In conclusion, this result confirmed that the DEN was one of the potent hepatocarcinogens. In experimental model of rats exposed to DEN, the results indicated that values of liver specific enzyme activities(AST, ALT, $\gamma$-GTP) and urine biopterin level could be useful complementary tumor indices.

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.

Aspirin is widely used for treatment or prophylaxis of many diseases. Although aspirin is used chronically for preventing cardiovascular diseases especially, liver function is rarely monitored because of unpredictable and uncommon hepatotoxicity induced by aspirin. We evaluated changes in liver function indicators and compared to acetaminophen and NSAIDs. We retrospectively analyzed EMR data (n=28788) of patients who took study drugs and had liver function tests (LFT) during study period from 2009.7.1 to 2010.6.30 at a tertiary hospital and evaluated the above information. Patients not having LFT results at these three standard points of time (baseline, during medication, and after finishing medication) were excluded. During medication, mean changes of Alanine transaminase (ALT), Aspartate transaminase (AST), Total Bilirubin (TB) were increased and that of serum albumin (Alb) was decreased, with the largest effect from aspirin (n=461; 16.8, 14.9, 0.28, -0.24) and the smallest from celecoxib (n=127; 3.4, 5.2, 0.11, -0.16). In addition, aspirin caused more changes of blood liver function indicators in patient group with liver disease (n=128, 27.4, 26.9, 0.53, -0.3) than those in patient group without liver disease (n=357, 12.5, 13.1, 0.23, -0.24). Taking low dose aspirin for prophylaxis purpose with long-term medication may be associated with liver injury. Our study is just a signal regarding the possibility of hepatotoxicity among patients taking low dose aspirin in a hospital setting, and thus it needs to be further investigated.

Children with abnormal liver function can often be seen in outpatient clinics or inpatients wards. Most of them have respiratory disease, or gastroenteritis by virus infection, accompanying fever. Occasionally, hepatitis by the viruses causing systemic infection may occur, and screening tests are required. In patients with jaundice, the tests for differential diagnosis and appropriate treatment are important. In the case of a child with hepatitis B virus infection vertically from a hepatitis B surface antigen positive mother, the importance of the recognition of immune clearance can't be overstressed, for the decision of time to begin treatment. Early diagnosis changes the fate of a child with Wilson disease. So, screening test for the disease should not be omitted. Non-alcoholic fatty liver disease, which is mainly discovered in obese children, is a new strong candidate triggering abnormal liver function. Muscular dystrophy is a representative disease mimicking liver dysfunction. Although muscular dystrophy is a progressive disorder, and early diagnosis can't change the fate of patients, it will be better to avoid parent's blame for delayed diagnosis.

Objectives : The aim of this study was to investigate effects of Chungganhaeju-tang on alcoholic fatty liver. Methods : Thirty patients with alcoholic fatty liver were included in this study. Chungganhaeju-tang was administered to subjects for 1 month. The changes of clinical symptoms and chemical liver function tests were evaluated before and after treatment. Results : Chungganhaeju-tang has effects on the improvement of clinical symptoms such as fatigue, anorexia, dyspepsia, nausea, and RUQ (Right Upper Quadrant) pain. On the chemical liver function test, serum AST, ALT, GGT, and TG level significantly decreased (P<0.05, by paired t-test). Conclusions : These results suggest that Chungganhaeju-tang has significant effects on the improvement of clinical symptoms and chemical liver function test with alcoholic fatty liver.

Objectives: The purpose of this study was to retrospectively assess the effectiveness of Chunggan plus extract (CGX) in improving liver function in a Korean medical clinic. Methods: We collected the data of inpatients who received CGX to improve abnormal liver function test (LFT) results from March 2016 to February 2020. We analyzed the changes in LFT and adverse events based on subjective symptom changes and creatinine results. Results: The data of eight patients, three male and five female, were selected by inclusion criteria (patients who did LFT before and after the prescription of CGX and who prescribed CGX more than 6 days) and exclusion criteria (patients who administered other herbal medicine for improving liver function except CGX and who are diagnosed with terminal stage of hepatobiliary cancer). As a cause of abnormal LFT, one case was diagnosed with alcoholic liver disease, two cases with non-alcoholic fatty hepatitis, and one case with cholecystitis. Three of the other four were suspected to have drug-induced hepatitis, and one case was determined to have an unknown cause. Most patients showed a decrease in LFT results (Aspartate transaminase 87.5%, Alanine transaminase 87.5%, and Alkaline Phosphatase 100%) without any critical adverse events. Conclusions: CGX may be an efficient and convenient herbal medicine for improving liver function regardless of the chief impression. Further study should be conducted to evaluate the effectiveness of CGX.

The purpose of this study was to evaluate the changes of liver function test before and after treatment in patients admitted to Korean medicine hospital. We checked liver function test level (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, direct bilirubin) of 147 patient who admitted in Korean medicine hospital from July 1, 2015 to June 30, 2018. The subjects were selected those who took herbal medicine continuously during the admission period and who performed liver function test on admission and before discharge. And the subjects were excluded those who had a history of liver and biliary disease at the time of admission or who took hepatoprotectants. Aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase significantly decreased compared with the values of admission(p<0.05), but total bilirubin and direct bilirubin were not significantly changed(p>0.05). On admission 31 patients(21.1%) had abnormal liver function and 6 patients(4.1%) had liver injury while 19 patients(12.9%) had abnormal liver function and 6 patients(4.1%) showed liver injury before discharge. This study suggests that herbal medicine may not injure liver function.

Mountain cultivated wild ginseng(MCWG) pharmacopuncture, which is known to have anti-cancer and anti-oxidation actions, was administered for clinical usage and changes in manifestations were observed on three patients suffering from pain attributed from liver dysfunctions. In two cases of hepatitis due to poisoning by drugs and one case of liver cirrhosis, long-term administration of MCWG pharmacopuncture yielded significant changes in AST and ALT, which are important indices for liver functions. Improved liver functions after the administration of MCWG pharmacopuncture suggest a need for investigation on future usage of MCWG pharmacopuncture on liver dysfunctions, hepatitis, liver cirrhosis, or liver cancer. Further studies on treating aforementioned disorders by MCWG pharmacopuncture are needed immediately.

In order to investigate radiation effects on the liver, functional changes of liver were analyzed after irradiation. Doses of 10 Gy, 15 Gy and 20 Gy were exposed partially to the liver of male rats(Sprague-Dawley) with X-ray(4MV linear accelerator) at room temperature. On 1, 2, 4 and 8 weeks after irradiation, liver tissues and sera of the animals were compared with those of unirradiated animal by liver function tests. Enzyme activities in sera such as alanine aminotransferase, aspartate aminotransferase, malondialdehyde. The content of malondialdehyde in the activities of many enzymes including alanine aminotransferase, aspartate aminotransferase in sera were increased slightly with increasing exposure dose in all experiments and the activities of these enzymes increased markedly in 20 Gy irradiated groups. From these above results, functional changes of the liver were induced in all irradiated groups. Damaged liver was recovered along with time collapse after irradiation to the doses of 10 Gy and 15 Gy while no recovery was deteced within 8 weeks after irradiation to 20 Gy. These results suggest that careful attention must be paid to liver not to be included in exposure field in radiation therapy.

Purpose: To investigate the safety of high dose hypofractionated radiotherapy (RT) in patients with small hepatocellular carcinoma (HCC) in terms of liver volumetric changes and clinical liver function. Materials and Methods: We retrospectively reviewed 16 patients with small HCC who were treated with high dose hypofractionated RT between 2006 and 2009. The serial changes of the liver volumetric parameter were analyzed from pre-RT and follow-up (FU) computed tomography (CT) scans. We estimated linear time trends of whole liver volume using a linear mixed model. The serial changes of the Child-Pugh (CP) scores were also analyzed in relation to the volumetric changes. Results: Mean pre-RT volume of entire liver was 1,192.2 mL (range, 502.6 to 1,310.2 mL) and mean clinical target volume was 14.7 mL (range, 1.56 to 70.07 mL). Fourteen (87.5%) patients had 4 FU CT sets and 2 (12.5%) patients had 3 FU CT sets. Mean interval between FU CT acquisition was 2.5 months. After considering age, gender and the irradiated liver volume as a fixed effects, the mixed model analysis confirmed that the change in liver volume is not significant throughout the time course of FU periods. Majority of patients had a CP score change less than 2 except in 1 patient who had CP score change more than 3. Conclusion: The high dose hypofractionated RT for small HCC is relatively safe and feasible in terms of liver volumetric changes and clinical liver function.
