Purpose: Liver function test abnormalities have been reported frequently in patients receiving total parenteral nutrition (TPN). In adults, it is known that liver complications decrease with the use of cyclic parenteral nutrition (CPN), especially if the shift to cycling was not too late. However, there are few studies about the effects of cycling on liver injury in children beyond the neonatal period. The aim of this study is to evaluate the effect of the early use of CPN on total parenteral nutrition induced hepatic dysfunction. Methods: Twelve sets of CPN in 11 children (2 months to 17 years) were included in this study. Data on underlying diseases, age, length of time on TPN, macronutrient intake, complications, and biochemical parameters were collected from clinical records. All children had received CPN in the early period of persistent transaminase elevation or cholestasis complicated by previous continuous PN. The duration of infusion off-time in CPN was 2 hours in patients less than 3 months of age and 4 hours in the older children. Results: All 12 cases showed elevated aminotransferase and 5 of them also showed cholestasis. Serum total bilirubin concentration was normalized in all 5 cases with median periods of 8 days (p<0.05) after initiation of CPN. ALT either decreased significantly or was normalized in all cases with median periods of 30 days (p<0.05) on CPN. The CPN was well tolerated without significant complication except for one case of hyperglycemia. Conclusion: The early use of cyclic parenteral nutrition had a beneficial effect in improving hepatic dysfunction complicated by TPN in children.

This study was conducted to improve the useful components and biological activity of Lentinula edodes fermented by lactic acid bacteria (LAB). Three LAB strains (Lactobacillus brevis KCCM 11904, L. plantarum KCCM 354469, and L. fermentum KCCM 12116) were inoculated and used for L. edodes hot water extract (10%, 20%, 30%) fermentation. LAB fermentation of L. edodes hot water extracts decreased pH and thus were more acidic than non-fermented L. edodes hot water extract. β-glucan and ergothioneine contents were increased by L. edodes in a concentration-dependent manner. The ergothioneine and β-glucan contents were highest in fermented with 30% L. edodes hot water extract fermented by L. plantarum and L. brevis (40.48 mg/100 g and 13.94%, respectively). The hepato-protective effect of fermented L. edodes hot water extracts by the three LAB were tested using Sprague-Dawley rat primary hepatocytes. In primary hepatocytes obtained following liver injury induced by acetaminophen, fermented L. edodes hot water extracts by the three LAB showed protective effects, as evident by reduction of the aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase liver markers. The collective results indicate that the fermented L. edodes hot water extracts obtained using LAB are potentially valuable in preventing or treating liver disease.

Korean traditional medicine has been used for the treatment of the various diseases based on both oriental medicinal theory and clinical trials. Thus, the prescriptions of Korean traditional medicine would be useful for the development of new therapeutics. This research focuses on the fundamental study in Korean traditional prescriptions for the development of new hepatoprotective agents. We found two prescriptions. Injinho-Tang and Osumogwa-Tang, showed the significant DPPH free radical scavenging and hepatoprotective effect, respectively. It is well-known that free radical scavenging effect is related to the prevention of various pathological events including liver injury. This paper deals with hepatoprotective effects on tacrine-induced cytotoxicity in Hep G2 cells, free radicals scavenging on both DPPH and superoxide of above two prescriptions. Hot water extract of Injinho-Tang did not show the significant hepatoprotective effect on tacrine-induced cytotoxicity in Hep G2 cells, however, it shows the significant scavenging effects for both DPPH and superoxide radicals. On the other hand, all of the hot water extracts of constituent herbal drugs in Injinho-Tang exhibited the promising protective effect on tacrine-induced cytotoxicity in Hep G2 cells. Of these, water extract of Rhei Rhizoma showed the most prominent effect on tacrine-induced cytotoxicity in Hep G2 cells. Bioassay-guided fractionation of Rhei Rhizoma extract has furnished four compounds, and their chemical structures have been identified by comparison of their spectral data with those of literature as chrysophanol (1), emodin (2), 3,5-dihydroxy-4'- methoxystilbene (3), and rhapontigenin (4), respectively. Among the isolated compounds, compounds 2-4 revealed the significant hepatoprotective effect in vitro when their $EC_{50}$ values compare with that of silybin, as a positive control. It also exhibited that emodin possessed the most hepatoprotective effect among these active compounds. In case of Osumogwa-Tang, its hot water extract showed the moderate protective effect on tacrine-induced cytotoxicity in Hep G2 cells. Hot water extract of Chaenomelis Fructus, one of the constituent herbal drug of this prescription, exhibited the significant hepatoprotective effect with $EC_{50}$ value of $7.8{\pm}0.1\;{\mu}g/ml$, however, it showed strong cytotoxicity in Hep G2 cells above the concentration of $25\;{\mu}g/ml$. It was revealed that both hot water extract of Evodiae Fructus and its butanol soluble fraction showed the moderate hepatoprotective effect but concentration-dependent activity in Hep G2 assay system. Two quinolone alkaloids, evocarpine and dihydroevocarpine, also tested for their hepatoprotective effects on tacrine-induced cytotoxicity in Hep G2 cells, however, these two compounds derived from the Evodiae Fructus as the major constituents did not show in vitro hepatoprotective effect. From these results, it would be necessary to further isolation of its hepatoprotective compounds from the butanol soluble fraction of the hot water extract of Evodiae Fructus.

Objective : The purpose of this study is to find out the possibility of application to herbal medicine's report form for adverse drug reaction (ADR) by reviewing and analyzing Asian countries's ADR report forms. Method : We investigated, compared, and analyzed ADR report forms (ADR-RF) of Asian countries's ADR institutions (ACAI), such as, Korea institute of drug safety & risk management and Dongguk university Ilsan oriental hospital (DUIOH) in Korea, national center for ADR monintoring (NCAM) in China, pharmaceuticals and medical devices agency (PMDA) in Japan, Ministry of Health and Welfare (MOHW) in Taiwan, and drug office, department of health, the government of the Hong Kong special administrative region (GHKSAR) in Hong Kong. Results : ADR-RF for ACAI included common contents, such as, patients information (name(initial), gender, age, weight), adverse event (AE)'s report information (Recognition and report for AE occurrence, first or follow up report, Severe AE), the detailed information of AE (the title of AE, onset & closing date of AE symptoms, the progress & results detailed test of AE), the information of AE's medicine (the types of medicine, product name, ingredient name, suspected or combination drug, single dose & frequency, dosage form, administration route, dealing for AE-suspected medicine), and AE reporter's information (reporter's information, institution's information). Taiwan had ADR-RF and the department exclusively for herbal medicine (HM), but others (except DUIOH) had not only no ADR report form but also contents for HM. Conclusion : ADR-RF for HM have to include the common contents of ACAI at least, as well as HM information related to ADR, such as the title, composition and types of HM, history related to HM's ADR, and the contents of drug-induced liver injury and so on. In addition, the main department of government for HM's ADR will be needed.

This study was carried out to investigate the effect of LAB (Lactic acid bacteria: Lactobacillus acidophilus, Bifidobacterium bifidum and Streptococcus thermophilus) on detoxication of damaged liver in carbon tetrachloride ($CCl_4$) and ethanol (25%)-treated rats. Rats had been daily (twice a day) pre-treated with saline (0.5 ml/kg: untreated group), $CCl_4$ (0.5 ml/kg: other groups) for 6 days. At seventh day, after treating rat with $CCl_4$ and then, mixture of LAB ($10^{11}$/0.5 ml: LAB group), saline (0.5 ml/kg: untreated group, $CCl_4$ group), and biphenyl dimethyl dicarboxylate (DDB) (50 mg/kg: DDB group) were treated orally with $CCl_4$ for 8 days. Ethanol is treated as the same manner instead of $CCl_4$. To investigate the hepatoprotective effect, rats treated with $CCl_4$ and ethanol were analyzed with serum GOT and GPT level. The GOT and GPT levels of LAB group was lower than the level of $CCl_4$ and DDB group. Especially, compared with data of $CCl_4$ group, GPT activity showed statistically significant result in the significance level of p < 0.05. The LAB group treated with ethanol also showed lower level of GOT and GPT than the other control groups treated with ethanol. The triglyceride level of serum decreased more in a group treated special materials (DDB and LAB group) than ethanol group. As well, the effect of LAB on the antifatigue has been investigated. The animals (10/group) were divided into 4 groups (untreated group, Carrier group, Red-ginseng group, LAB group). Each group was given carrier (0.9 mg/0.2 ml), red ginseng extract (200 mg/kg), and mixture of LAB ($10^{11}$/0.2 ml). Special materials were given for three weeks. After finishing treating through oral, horizontal wire test, rotarod test, and forced swimming test were performed. The time of resistance to fatigue of the group, fed with mixture of LAB, was longer than the time when mice treated with red-ginseng that the effect was already revealed. The result of this study revealed that LAB could decrease hepatocelluar injury compared with rats treated orally with $CCl_4$ and ethanol, and could also decrease fatigue.

FK506 is a widespread immunosuppressive drug after liver transplantion in patients with advanced-stage hepatocellular carcinoma. Dexamethasone is frequently used as co-treatment in cytotoxic cancer therapy, e.g. to prevent nausea, to protect normal tissue or for other reasons. Our aim was to investigate antitumor effects of FK506 in Hep3B cells, one of differentiated human hepatocellular carcinoma cell lines and inhibitory effects of dexamethsone on FK506- induced antitumor effects. Cell injury was evaluated by biochemical assays as cell viability, lactate dehydrogenase (LDH) and reactive oxygen species (ROS) in Hep3B cells. Intracellular calcium concentration ([$Ca^{2+}$]i) and the level of activation of the c-Jun-N-terminal kinase (JNK) and the Bax protein in cultured Hep3B cells was measured. Exposure of 0.1 ${\mu}M$ FK506 to Hep3B cells led to cell death accompanied by a decrease in cell viability and an increase in LDH, ROS and [$Ca^{2+}$]i. FK506 induced an increase in activity of Bax and JNK protein but inhibited the activity of Bcl-2 protein. Treatment of dexamethsone, per se, had no effects on cell viability, LDH and ROS. However, co-treatment of FK506 and dexamethasone diminished the FK506-induced LDH release, ROS generation and JNK activation. These results demonstrate that FK506 has antitumor effect in Hep3B cells but the combination of FK506 and dexamethasone antagonizes the FK506-induced antitumor effects.

Objectives : Seventh-day Adventists is well known to place a strong doctrinal emphasis on healthy life style that do not consume tobacco, alcohol or pork, and many adhere to a lacto-ovo-vegetarian lifestyle. This study aimed to investigate the difference of mortality between Korean Seventh-day Adventists and the general Korean population. Methods : We got 592 mortality data of Adventist cemetery in Seoul city and Kyunggi provincce of Korea, which contains information on causes of death for 2000-2004. Also we used mortality data of the general Korean population in Korea National Statistics Office for 2000-2004. Results : The mean age at death was 70.45 in Korean Adventists, 65.63 in the general Korean population. Higher neoplasm cause of death, such as of stomach, liver and breast, were observed in Korean Adventists than the general population. The death cause of injury, poisoning and external causes, and cerebrovascular disease were higher in the general population than Korean Adventists. The death cause of stomach cancer was lower in Korean Adventists who had above 10 years religious period than general population above age 50 years. In male, the death cause of lung cancer was lower in Korean Adventists than the general population. Conclusions : The results point to the importance of healthy life-style in Korean peoples, and indicate that lifestyle changes in the population might change the causes of death.

Background: Multiple trauma patients have rapidly increased due to traffic accidents, industrial disasters, incidental accidents, and violence. Multiple trauma can involve injuries to the heart, lung, and great vessels and influence the lives, necessitate prompt diagnosis and treatment. Most of the thoracic injuries can be managed with conservative method and simple surgical procedures, such as closed thoracostomy, but in certain cases open thoracotomy is necessary. Materials and methods: The author analyzed the surgical result of 70 cases of open thoracotomy after multiple organ injury including thoracic organ. Results: The most common type of thoracic lesion was hemothorax with or without pneumothorax and diaphragmatic rupture was the second. Sixty percent of the patients were associated with bone fractures, 42.9% with abdominal injuries, and 37.1% with head injuries. The modes of operation were ligations of torn vessels for bleeding control(48.6%), repair of diaphragm(35.7%), and repair of lung laceration(25.7%) in this order of frequency and additional procedures were splenectomy(14.3%), hepatic lobectomy (8.6%) and repair of liver lacerations(5.7%). Postoperative complications were atelectasis (8.6%), wound infection (8.6%), and pneumonia(4.3%). Postoperatively six patients died(The mortality rate was 8.6%) and the causes of death were respiratory failure(2), acute renal failure(2), sepsis(1), and hypovolemic shock(1).

Inflammatory and fibrotic responses are accelerated during the reperfusion period, and excessive fibrosis and inflammation contribute to cardiac malfunction. NecroX compounds have been shown to protect the liver and heart from ischemia-reperfusion injury. The aim of this study was to further define the role and mechanism of action of NecroX-5 in regulating inflammation and fibrosis responses in a model of hypoxia/reoxygenation (HR). We utilized HR-treated rat hearts and lipopolysaccharide (LPS)-treated H9C2 culture cells in the presence or absence of NecroX-5 ($10{\mu}mol/L$) treatment as experimental models. Addition of NecroX-5 significantly increased decorin (Dcn) expression levels in HR-treated hearts. In contrast, expression of transforming growth factor beta 1 ($TGF{\beta}1$) and Smad2 phosphorylation (pSmad2) was strongly attenuated in NecroX-5-treated hearts. In addition, significantly increased production of tumor necrosis factor alpha ($TNF{\alpha}$), $TGF{\beta}1$, and pSmad2, and markedly decreased Dcn expression levels, were observed in LPS-stimulated H9C2 cells. Interestingly, NecroX-5 supplementation effectively attenuated the increased expression levels of $TNF{\alpha}$, $TGF{\beta}1$, and pSmad2, as well as the decreased expression of Dcn. Thus, our data demonstrate potential antiinflammatory and anti-fibrotic effects of NecroX-5 against cardiac HR injuries via modulation of the $TNF{\alpha}/Dcn/TGF{\beta}1/Smad2$ pathway.
