Objectives : The present study investigated effects of Artemisia Capillaris Thunberg ethanol extract(EtOH ext). on lowering lipid, anti-oxidation and concentration of plasma inflammatory mediators using rat fed on high oxidized fat. Methods : We divided fat sprague-dawley rats fed on high oxidized into 4 groups. They were normal group, feed with 100 mg/kg Artemisia Capillaris Thunberg group, feed with 200 mg/kg Artemisia Capillaris Thunberg group and feed with 300 mg/kg Artemisia capilaris Thunberg group. They were administered for 4 weeks. We measured concentration of plasma free fatty acid(FFA), plasma triglyceride, plasma total cholesterol, and plasma low density lipoprotein-cholesterol(LDL-cholesterol), plasma high density lipoprotein-cholesterol(HDL-cholesterol), concentration of liver total cholesterol and liver triglyceride (TG), concentration of plasma thiobarbituric acid reactive substance(TBARS) and liver thiobarbituric acid reactive substance(TBARS), glutathione peroxidase (GSH-Px) activity, superoxide dismutase(SOD) activity and catalase(CAT) activity, plasma nitric oxide(NO), ceruloplasmin and ${\alpha}-glycoprotein$. Results : 1. The Artemisia Capillaris Thunberg EtOH ext. groups showed low concentration of plasma FFA, plasma triglyceride, plasma total cholesterol and plasma LDL-cholesterol compared to control group. However, concentration of plasma HDL-cholesterol was increased in the Artemisia Capillaris Thunberg EtOH ext. groups. 2. Concentration of liver total cholesterol and liver TG showed a significantly decrement in all Artemisia Capillaris Thunberg EtOH ext. groups than that of control group. 3. The Artemisia Capillaris Thunberg EtOH ext. groups showed lower values in concentration of plasma TBARS and liver TBARS than that of control group. The values of GSH-Px activity, SOD activity and CAT activity were increased in the Artemisia Capillaris Thunberg EtOH ext. groups. 4. The values of plasma NO, ceruloplasmin and ${\alpha}-glycoprotein$ were decreased in Artemisia Capillaris Thunberg EtOH ext. groups. Conclusions : Based on the results in this study, the Artemisia Capillaris Thunberg EtOH ext. showed a positive effect in lowering lipid, anti-oxidation and decrement of plasma inflammatory mediators.

In biological system, there are enzymes such as superoxide dismutase(SOD), catalase and glutathione(GSH) peroxidase which scavenge reactive oxygen species as well as antioxidants such as ceruloplasmin, albumin and nonprotein-bound SH including GSH related to defense mechanism. In the present study, the protective effects of ginsenoside $Rb_2$ against oxidative stress were investigated in the SAM-R/1 mice. Treatment with ginsenoside $Rb_2$ significantly increased Cu, Zn-SOD and Mn-SOD in the liver. Ginsenoside $Rb_2$ tended to increase hepatic catalase activity and significantly increased serum albumin and nonprotein-bound SH levels in the liver. But treatment with ginsenoside $Rb_2$ showed a significant decrease in hepatic malondialdehyde(MDA) levels compared to control group. Furthermore, we compared the effects in the hepatic SOD, MDA and serum albumin. These findings suggest that the increase of antioxidants by ginsenoside $Rb_2$ results in the protective effects against reactive oxygen species.

Methotrexate (Mtx), used for its anticancer and immunsuppresive properties, is known to be a nephrotoxic agent. We aimed to investigate the effects of lycopene (Lyc) alone or combined with melatonin (Mel) on Mtxinduced nephrotoxicity since both of these agents have antioxidant and anti-inflammatory effects. Nephrotoxicity was induced by intraperitoneal administration of methotrexate at a dose of 20 mg/kg. Treatment both with Lyc alone and Lyc combined with Mel provided significant reduction in tumor necrosis factor-alpha, interleukin 1-beta and ceruloplasmin levels in Mtx administered rats. Hovewer, Lyc combined with Mel provided a significant reduction also in NO levels. Hstopathological examination showed that there was an obvious improvement in the degenerative changes compared to Mtx administrated group with the Lyc combined Mel group giving best protection. In conclusion Lyc alone and combined with Mel provided significant improvement against renal damage caused by Mtx, preseumably via antioxidant and anti-inflammatory activities.

Liver cancer is a leading cause of tumor-related mortality, Diethylnitrosamine (DEN) is one of the most extensively studied hepatic carcinogens to date. In this study, the mRNA expression profile in DEN-induced liver tumors in mice was analyzed using DNA microarrays. We report increased expression of genes that participate in hypoxia response, including metallothionein 1 (Mt1), metallothionein 2 (Mt2), fatty acid synthase (Fasn), transferrin (Trf), adipose differentiation-related Protein (AdfP) and ceruloplasmin (CP), as well as those involved in predisposition and development of cancers, such as cytochrome P450 2A5 (Cyp2a5), alpha 2-HS-glycoprotein (Ahsg) and Jun-B oncogene (Junb). The hepatic iron regulatory peptide, hepcidin (Hampl), was downregulated in DEN-stimulated liver tumors. Expression of tumor suppressor genes, such as tripartite motif protein 13 (Trim13), was decreased under these conditions. The data collectively indicate that DEN-induced tumor development can be exploited as a possible model for liver cancer, since this process involves various genes with important functions in hepatic carcinogenesis.

Background: Wilson disease (WD) is an autosomal recessive disorder of copper transport and characterized by degenerative changes in the brain, liver dysfunction, and Kayser-Fleischer rings due to toxic accumulation of copper. Since the identification of Wilson disease gene (ATP7B), more than 80 mutations have been detected among the different ethnic groups. Methods: Twenty three children with Wilson disease were included in this study. They were all diagnosed by low serum ceruloplasmin and increased 24 hour urinary copper excretion with characteristic clinical findings. We analysed WD gene mutation by assessing the nucleotide sequence of exon 7, 8, 9 and 10 including intron-exon boundaries of ATP7B gene from genomic DNA. Results: Arg778Leu mutation was identified in 16 WD patients; three were homozygous and 13 were heterozygous for this mutation. Of the 46 alleles, 19 alleles had a Arg778Leu mutation (19/46=41%). Homozygote patients had neurologic forms of WD. Arg778Leu mutation was not found among 50 normal healthy persons. Conclusion: Arg778Leu mutation is a common mutation in Korean WD gene. Arg778Leu mutation screening might be used as a useful supplementary diagnostic test in some patients to confirm Wilson disease in Korea.

Objective: This study was conducted to investigate the effects of normal and heat stress environments on growth performance and, selected physiological and immunological parameters, caecal microflora and meat quality in Cobb 500 and Ross 308 broilers. Methods: One-hundred-and-twenty male broiler chicks from each strain (one-day-old) were randomly assigned in groups of 10 to 24 battery cages. Ambient temperature on day (d) 1 was set at 32℃ and gradually reduced to 23℃ on d 21. From d 22 to 35, equal numbers of birds from each strain were exposed to a temperature of either 23℃ throughout (normal) or 34℃ for 6 h (heat stress). Results: From d 1 to 21, strain had no effect (p>0.05) on feed intake (FI), body weight gain (BWG), or the feed conversion ratio (FCR). Except for creatine kinase, no strain×temperature interactions were observed for all the parameters measured. Regardless of strain, heat exposure significantly (p<0.05) reduced FI and BWG (d 22 to 35 and 1 to 35), immunoglobulin Y (IgY) and IgM, while increased FCR (d 22 to 35 and 1 to 35) and serum levels of glucose and acute phase proteins (APPs). Regardless of temperature, the Ross 308 birds had significantly (p<0.05) lower IgA and higher finisher and overall BWG compared to Cobb 500. Conclusion: The present study suggests that the detrimental effects of heat stress are consistent across commercial broiler strains because there were no significant strain×temperature interactions for growth performance, serum APPs and immunoglobulin responses, meat quality, and ceacal microflora population.

A few researchers have reported that major depression may be associated with higher levels of positive acute phase proteins(APPs), such as haptoglobin(Hp), ${\alpha}1$-antitrypsin(${\alpha}1AT$), ceruloplasmin(Cp) and lower levels of negative APPs(visceral proteins), such as albumin(Alb) and transferrin(Tf). Elevated levels of positive APPs and a drop in negative APPs constitute important indicators of immune activation. This study was designed to investigate whether altered serum concentrations of positive APPs and of negative APPs reflect the state of depression. Twenty patients who fulfilled DSM-III-R criteria for major depressive disorder and for dysthymic disorder and twelve normal healthy controls were included. The authors measured positive APPs(Hp, ${\alpha}1AT$, Cp) and negative APPs(Alb, Tf) using rate nephelometry and bromcresol green method. 1) There were significant increases of ${\alpha}1AT$, Cp in major depressed patients as compared with normal controls. Trends towards higher Hp and lower Alb, Tf in major depressed patients were observed. 2) No significant difference of APPs concentrations between dysthymic patients and normal controls was found. 3) Severity of depression(HDRS, BDI score) was related to Hp, Cp, ${\alpha}1AT$ value positively. Our findings are partially compatible with the hypothesis that major depression may be accompanied by acute phase response with higher levels of positive APPs and lower levels of negative APPs.
