The reported risk factors for gallstone disease (GD) are old age, female sex, obesity, metabolic syndrome and migrants. Many younger adults tend to live in Jeju City, where transportations are convenient and commercial activities are active. Whereas, older people tend to live in Seogwipo City, because they engaged in fisheries and agriculture. Rates of migrants and old age could affect the prevalence of GD among residents in two regions. Therefore, the purpose of this study was to compare the GD prevalence and analyze risk factors affecting GD including residencies. A total of 13,050 subjects who visited a single health medical check-up center on Jeju Island between 2012 and 2019 were included. We performed univariate and multivariate analysis to identify risk factors for GD. The prevalence of GD among residents were 5.7% in Jeju City and 5.8% in Seogwipo City, respectively. Multivariate analysis revealed that age (P=0.008), body mass index (P=0.044), high-density lipoprotein cholesterol (P=0.006) and gamma-glutamyl transferase (P=0.013) were independent factors affecting GD. The old age, mean higher body mass index, gamma-glutamyl transferase and mean lower high-density lipoprotein cholesterol were independent risk factors affecting GD. However, residencies did not affect the prevalence of GD.

This study compared the results of hemolyzed samples and re-collected samples to investigate a hemolysis influence and an acceptable hemolysis index (HI). Before and after hemolysis, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), amylase (Amy), direct bilirubin (D-bil), total bilirubin (T-bil), creatine phosphokinase (CK), gamma glutamyl transferase (GGT), iron, potassium (K), lactate dehydrogenase (LDH), magnesium (Mg), phosphorus (Phos), total protein (TP), and uric acid (UA) showed significant results in the paired t-test. LDH, K, iron, AST, CK, GGT, TP, Amy and Phos had a high correlation between the degree of hemolysis and the results of samples. When comparing Roche's cut-off HI with HI^QChigh obtained using quality control (QC) high standard deviation (SD), AST, D-bil, CK, and LDH were similar, but Amy, GGT, K, iron, Phos, and TP were lower than the cut-off HI of Roche, while ALP and ALT were higher. Some analytes which showed no significant results in the paired t-test, were found to have significant results in HI>200. Hence, it is suggested that the hemolyzed sample should be rejected if HI>200. Based on this study that some analytes were affected when HI<100, we recommend to set the standard of hemolysis starting from HI>50.

The aim of the present investigation was to evaluate the effect of A ferruginea extract on Dalton's lymphoma ascites (DLA) induced tumours in BALB/c mice. Experimental animals received A ferruginea extract (10 mg/kg.b.wt) intraperitoneally for 14 consecutive days after DLA tumor challenge. Treatment with extract significantly increased the life span, total white blood cell (WBC) count and haemoglobin (Hb) content and decreased the level of serum aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma glutamyl transferase (${\gamma}$-GT) and nitric oxide (NO) in DLA bearing ascites tumor models. In addition, administration of extract significantly decreased the tumour volume and body weight in a DLA bearing solid tumor model. The levels of pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-${\alpha}$), interleukin-1 beta (IL-$1{\beta}$), interleukin-6 (IL-6) and granulocyte monocyte-colony stimulating factor (GM-CSF), as well as pro-angiogenic growth factors such as vascular endothelial growth factor (VEGF) and inducible nitric oxide synthase (iNOS) were elevated in solid tumour controls, but significantly reduced by A ferruginea administration. On the other hand, the extract stimulated the production of interleukin-2 (IL-2) and interferon-gamma (IFN-${\gamma}$) in animals with DLA induced solid tumours. Increase in $CD4^+$ T-cell population suggested strong immunostimulant activity for this extract. GC/MS and LC/MS analysis showed quinone, quinoline, imidazolidine, pyrrolidine, cyclopentenone, thiazole, pyrazole, catechin and coumarin derivatives as major compounds present in the A ferruginea methanolic extract. Thus, the outcome of the present study suggests that A ferruginea extract has immunomodulatory and tumor inhibitory activities and has the potential to be developed as a natural anticancer agent.

The root of Adenophora triphylla is widely used as traditional herbal medicine in Korea. We studied its effects on sodium nitroprusside (SNP) cytotoxicity and antioxidant genes expression in HepG2 cells. To study whether Adenophora triphylla ethylacetate extract (ATea) inhibited NO-induced cell death, HepG2 cells were preincubated for 24 hr with 50 and 100 $\mu$g/mL ATea followed by 24-hr exposure to 0.5 mM SNP (exogenous NO donor). No-induced cytotoxicity was inhibited by pretreatment of ATea, as assessed by mitochondrial dehydrogenase activity (MTT assay). We further investigated the effects of ATea on mRNA levels of various enzymes of the antioxidant system such as Cu, Zn superoxide dismutase (SOD 1), Mn SOD (SOD 2), glutathione peroxidase (GPx), catalase and several enzymes of the glutathione metabolism [glutathione reductase (GR), $\gamma$-glutamyl-cystein synthetase (GCS), glutathione-S-transferase (GST), $\gamma$-glutamyltranspeptidase ($\gamma$-GT), glucose-6-phosphate dehydrogenase (G6PD)] by RT-PCR. CAT, GCS, GR and G6PD mRNA levels were increased after treatment with ATea. The SOD 1, SOD 2, GPx, GST and $\gamma$-GT mRNA levels were not affected in ATea-treated HepG2 cells. We concluded that ATea have an indirect antioxidant effects, perhaps via induction of CAT, GCS, GR and G6PD.

The aim of this study was to investigate the impact of participation in the 622 km hyper-ultra-marathon on hepatic metabolism and renal function in middle-aged men. Healthy middle-aged male amateur ultra-marathoners between the ages of 40 and 60. Blood was collected at the pre-race, immediately after 300 km, 622 km hyper-ultra marathon race, 72 hours (3 day) and 144 hours (6 day) after the race, AST (aspartate aminotransferase), ALT (alanine aminotransferase), ALP (alkaline phosphatase), ${\gamma}$-GTP (gamma glutamyl transferase), T-Bil (total bilirubin), D-Bil (direct bilirubin), T-protein (total protein), albumin, uric acid, BUN (blood urea nitrogen), creatinne were analyzed. ALP was significantly increased at 300 km, 622 km, day 3 and day 6 than the pre-race. ${\gamma}$-GTP, T-protein, albumin, uric acid, BUN and creatinine were not significantly different between the distances and the recovery period respectively. AST and ALT were significantly increased at 300 km, 622 km, day 3 and day 6 than the pre-race, respectively (P<0.05) at day 3 and day 6 they showed significant decrease from 300 km and 622 km, respectively (P<0.05). T-Bil and D-Bil increased significantly at 300 km and 622 km, respectively (P<.05) and significantly decreased at day 3 (P<0.05) compared to the pre-race, at day 3 and day 6 they were decreased significantly than 300 km and 622 km, respectively (P<0.05). In conclusion, no disturbance of renal function was observed according to the distances and between the recovery period of 622 km hyper-ultra marathon race, but reversible hepatocyte function could be degraded and some hemolysis of blood vessels was induced.

Acute hepatitis is caused by virus, alcohol. toxins and drugs. Clinical symptoms of acute hepatitis are severe fatigue, jaundice, nausea, hepatomely, lymphadenopathy. We encountered two cases of acute hepatitis, one C type viral hepatitis and the other hepatitis by overuse of medicine. The symptoms of the latter are severe fatigue, petechia and heartburning. The symptoms of the latter are severe fatigue, nausea, dyspepsia, yellow urine and skin. We recognized that total bilirubin. direct bilirubin, serum transaminase, alkaline phosphatase and gamma glutamyl transferase were elevated. We treated both patients with herb medicine(Gagamsaenggan-tang). Gagamsaenggan-tang has been used to hepatic diseases and have been known to have beneficial effects. The patients' symptoms began to improve after about two weeks of treatment. After 3 weeks on medication, the clinical symptoms and liver function of two patients were improved.

This study was performed to investigate the protective effect of Houttuynia cordata Thunb on hepatotoxicity in carbon tetrachloride$(CCI_4)$ intoxicated rats. The examined effects hexane, chloroform, butanol and water fractions prepared from the Houttuynia cordata Thunb methanol exlract and rats were administrated with those orally once a day for successive 6 days, fellowed by treaoent with $CCl_4$ on the sixth day. After 6 days, the activities of aminotransferase, alkalinephosphatase, ${\gamma}-glutamyl$ transpeptidase, lactate dehydrogenase and contents of triglyceride, hepatic lipid peroxide in butanol fraction pretreated rats were significantly decreased compared to the only $CCl_4$ treated rats, also depletion glutathione content induced by treatment with $CCl_4$ was prevented by butanol fraction pretreated rats. In addition, activities of hepatic superoxide dismutase, catalase, glutathione peroxidase in butanol fiaction pretreated rats were significantly decreased compared to the only $CCl_4$ treated rats, but the activity of hepatic glutathione-S-transferase was not significantly effect. These results suggest that butanol fiuction of Houttuynia cordata Thunb methanol extract have potent hepatoprotective effect against carbon tetrachloride intoxicated rats.

The aim of the present investigation was to evaluate the effect of A.nilotica extract against Dalton's ascitic lymphoma (DAL) induced solid and ascitic tumors in BALB/c mice. Experimental animals received A.nilotica extract (10 mg/kg.bw) intraperitoneally for 10 and 14 consecutive days before induction of solid and ascitic tumors, respectively. Treatment with A.nilotica extract significantly decreased the development of tumor and percentage increase in body weight when compared to DAL induced solid tumor control group, also increasing the life span, restoring the total white blood cell count and hemoglobin content and significantly decreasing the levels of serum aspartate transaminase (SGPT), alanine transaminase (SGOT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and nitric oxide (NO) when compared to DAL induced ascitic tumor controls. The treatment also reduced significantly the cellular glutathione (GSH) and nitric oxide levels in treated animals. Histopathological studies also confirmed protective influence. The outcome of the present work indicates that A.nilotica extract could be used as natural anticancer agent for human health.

This study was performed to investigate the pathphysiological side effects of chloramphenicol (CAP) on olive flounder, Paralichthys olivaceus. 150 mg/kg/bw/day of CAP was orally administered forcedly to flounder for 4 days and then the flounder was monitored for 11 days. The level of hematocrit was significantly decreased from 2 day to 3 day of CAP treatment in CAP-treated group. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma glutamyl transferase (GGT) were slightly increased during the treatment of CAP and gradually decreased after the treatment of CAP. The levels of blood urea nitrogen (BUN) and creatinine kinase (CK), although not significant, were slightly increased during the treatment of CAP. The level of lactate dehydrogenase (LDH) was not changed during the treatment of CAP but slightly increased after the treatment of CAP. However, no histopathological changes were observed in various organ after the treatment. From these results, it is suggest that CAP can evoke several side effects on haematopoietic organs in olive flounder.
