Objectives: This study investigated the effects of Scutellariae Radix extract (SRE) on lipids metabolism, oxidation and the production of pro-inflammatory cytokines in rats fed highly oxidized fat. Methods: To induce obesity, male Sprague‐Dawley rats were fed a highly oxidized fat diet for 10 weeks. SRE at 100 mg/kg were administered orally to obesity-induced rats for 6 weeks, and their lipid metabolism, oxidation and production of pro-inflammatory cytokines were examined. Results: The concentrations of free fatty acid, triglyceride, total cholesterol, and low density lipoprotein-cholesterol in plasma decreased in SRE-treated groups, although the difference was not significant between control and SRE-treated groups, while that of high density lipoprotein-cholesterol significantly increased in SRE group. The concentrations of total cholesterol and triglyceride in the liver were tended to decrease in SRE-treated group. The concentrations of thiobarbituric acid in plasma and liver were lower in SRE group than in control group. The levels of glutamic oxaloacetic transaminase and glutamic pyruvic transaminase in plasma were decreased in SRE group. Activities of glutathione peroxidase, superoxide dismutase, and catalase in liver were tended to increase in the SRE group. The plasma concentrations of interleukin $(IL)-1{\beta}$, tumor necrosis factor $(TNF)-{\alpha}$ and IL-6 were lower in SRE group than in control group, while that of IL-10 was higher. The liver concentrations of $IL-1{\beta}$, $TNF-{\alpha}$, and IL-6 were tended to decrease while that of IL-10 tended to increase in SRE group. Conclusions: Finally SRE could be used in the production of nutraceuticals for lowering lipids and exerting anti-oxidation and anti-inflammatory effects in obesity rats fed highly oxidized rat.

For the purpose of investigating whether the administration of sunflower pollen load has any influence upon liver cholesterol metabolism in mouse, lipids were isolated from sunflower pollen load, identified and quantitated by thin-layer and gas liquid chromatographies. We also studied changes in liver cholesterol level in mouse according to the amount and the period of pollen load administration. Lipids of sunflower pollen load were constituted 84.10f of neutral lipid, 10.50% of glycolipid and 5.40% of phospholipid. The main fatty acid contents of neutral lipid, glycolipid and phospholipid were ranged 28.48 to 33.70% of linoleic acid, 12.90 to 47.50% of palmitic acid ana 11.20 to 12.20% of oleic acid, however, phospholipid contained more palmitic acid than the other lipids. The body weight of the Pollen fed mouse significantly increased during experimental Period in comparison with control group. From the fact tat the ratio of liver weight to body weight of pollen fed mouse was smaller than that of control group, it was proved that liver lipid metabolism of pollen fed mouse was more active than that of control group. During early experimental period, liver cholesterol level had been increased according to pollen load administration(P.O), and then the level decreased rapidly to the similar level to that of control group at the end of the period.

In the view of oriental medicine, the liver is the general of the army in its function of protecting against the enemy. So this concept is very closely associated to the immunological function. Its relations with immunological function are as follows. 1. The liver produces most of the proteins and converts them with hepatocytes, composes 80% in total reticuloendothelial system with Kuffer cells & endothelial cells and has typical structure of sinusoidal vessels closely related with the blood system. 2. The liver plays an important role in innate immunity with Kuffer cells as well as with the molecules that the liver produces, related to complementary systems. 3. In the embryonic period, the liver is associated with immune associated cell growth and their maturation. After birth, it is associated with removing old red blood cells and with systematically modulating immune system through hormone metabolism. 4. The liver controls the autoimmune disease resulting from immune complex by removing molecules like immune complex. 5. In the processing of blood 19A from the digestive system, the liver has an important role in protecting the body from unnecessary immune responses. 6. In the oriental medical view, liver plays a major role in the immune function by storing blood and dispersing stagnated hepatoqi with the help of the kidneys and spleen.

Objective: The purpose of this study was to examine the protective efficacy of GHT on alcoholic liver injury. Methods: We measured the rate of alcohol oxidation, serum level of liver enzyme, lipid peroxidation level in liver tissue, and inflammatory related cytokine expressions in the liver. Results : GHT showed liver protective effects, lowered the levels of AST and LDH in serum and inhibited lipid peroxidation in liver tissue, and enhanced alcohol oxidation. GHT treatment up-regulated IL-10 in the liver, whereas it down­regulated $TNF-\alpha,\;TGF-\beta$, and Fas ligand. Conclusion : From these results, GHT is presumed to work in the liver in protective roles not through the pathway of alcohol metabolism but mainly by anti-inflammation activity in our model.

One mechanism of free-radical production by ethanol is suggested to be through the intracellular conversion of XDH to XO by increased ratio of NADH to NAD. The major mechanism for physiological compensation of cytosolic NADH/NAD balance is the malate/aspartate shutfie. Therefore, it is important to develop the method to improve the efficiency of malate/aspartate shuttle in ethanol metabolism. In the present study, various amino acids and organic acid involved in the shuttle were tested for their functional efficiency in modulating shuttle in the ethanol-perfused rat liver. The rate of ethanol oxidation in the liver perfused with aspartate alone or aspartate in combination with pyruvate, respectively, was increased by about 10% compared to control liver, but not in the tissues perfused with glummate, cysteine or pyruvate alone. Though glummate, cysteine and pyravate did not affect the ethanol oxidation significanfiy, they showed some suppresive effect on the ethanol-induced radical generation monitored by protein carbonylation analysis. Among the tested components, aspartate is confirmed to be the most efficient as a metabolic regulator for both ethanol oxidation and ethanol-induced oxidative stress in our perfusion system. These effects of aspartate would result from NAD recycling by its supplementation through the coupled aspartate aminotransferase/malate dehydrogenase reactions and the malate-aspartate shuttle.

This study was designed to investigate effects of lobster shrimp chitosan on serum and liver lipid levels in rats fed high fat and cholesterol diets. Male Sprague-Dawley rats of 4-weeks old, weighing 70$\pm$5g, were fed experimental diets for 3 weeks: basal diet+5% cellulose(group 1), high lipid diet+5% cellulose(group 2, control group), high lipid diet+5% balloon flower root(group 3), high lipid diet+5% cellulose(group 4, high lipid diet+5% lobster shrimp chitosan(group 5). Concentrations of total cholesterol, HDL-cholesterol, LDL-cholesterol, free cholesterol, cholesteryl ester, triglyceride, phospholipid in serum and liver were determined. The results obtained were as followes: Serum total cholesterol concentration were significantly reduced in all supplemented group compared with control. HDL-cholesterol concentrations were higher in groups 1, 4, and 5 and the ratios of HDL-cholesterol to total cholesterol concentration were higher in groups 1, 4, while the atherogenic-indices were lower in groups 1, and 4 than control. Concentrations of LDL, LDL-cholesterol and free cholesterol, cholesteryl ester were significantly lower in all supplemented groups than the control group. Concentrations of phospholipid and triglyceride were lower in groups 3, 4, 5, while activities of GPT and GOT were significantly lower in groups 4, 5 than the other group. Concentrations of calcium, magnesium and phosphorous were high in all treatment groups compared to the control group. Liver contents of total cholesterol, free cholesterol and cholesteryl ester were lower in the groups 1, 3, 4, and 5 than in the control group, especially lower in groups 1, and 5. Liver triglyceride and phospholipid concentrations were significantly lower in the groups 1, and 5 than in the other groups. The results from the data suggested that the experimental diet containing 5% lobster shrimp chitosan was effective to reduce the serum and liver lipids.

The aim of this study was to investigate the effect of Taeeumjowuitanggagam-bang (TJV) on the mRNA expression of Sterol regulatory element binding proteins (SREBPs), Tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and Interlukin-6 (IL-6) that are considered to play an important role in lipid and glucose metabolism. For diet-induced obese studies, we split mice into 2 groups. The low fat diet group (LFD, n=8) were supplied with general diet for 10 weeks and the high fat diet group (HFD, n=18) were supplied with 60 kcal% fat diet for 10 weeks. And then The HFD group, the diet-induced obese group, were divided into 3 groups ; a group supplied with normal saline, a group treated with TJV 200 mg/kg and a group treated with TJV 500 mg/kg. They were treated orally with TJV and measured their body weight every day during 10 weeks. After that, we measured mRNA expressions of TNF-$\alpha$, IL-6 and SREBP-1c in liver, and blood concentrations of glucose, total cholesterol and triglyceride too. The results are as follows. The TJV reduced glucose and total cholesterol of blood concentration. The TJV reduced the mRNA expressions of TNF-$\alpha$ and SREBPs in liver. However, We couldn't find the TJV effects on the mRNA expression of IL-6, triglyceride blood concentration, and body weight among groups. The TJV stained liver tissue less red than control group. These results suggest that TJV may be effective for regulation of lipid and glucose metabolism in liver.

The object of this work was to study the pharmacokinetic differences and the cause of these differences in cirrhotic rats induced by biliary obstruction when aminophylline (8 mg/kg as theophylline, i.v.) was administered. The concentrations of theophylline and its major metabolite (1,3-dimethyluric acid) in plasma were determined by HPLC. In addition, formation of 1,3-dimethyluric acid from theophylline in microsomes and the changes in the activity of drug metabolizing enzymes, which are suggested to be involved in theophylline metabolism, were determined. In cirrhotic rats, the systemic clearance of theophylline was reduced to 30% of the control value while AUC (area under the palsma concentration-tie curve) and (t1/2)$\beta$ were increased 1.3 fold and3.5 fold, respectively. The formation of 1,3-dimethyluric acid was decreased to 30% of the control value in microsomes of cirrhotic rat liver. In cirrhotic rat liver, activities of aniline hydroxylase (CYP2E1 related), erythromycin-N-demethylase (CYP3A related), and methoxyresorufin-O-demethylase (CYP1A2 related), which were reported to be related with theophyline metabolism, were decreased to 67%, 53%, and 76% that of normal rat liver, respectively. From the results, it can be concluded that in cirrhotic rats induced by biliary obstruction, the total body clearance of theophylline is markedly reduced and it may be due to decreased activity of drug metabolizing enzymes in liver.

The purposes of this studies were to investigate the effect of dietry Se levels and alcohol administration on the lipid hyperoxidation and the lipid metabolism in the rat. Seventy two male rats of Sprague-Dawley Strain weighting about 58~629 were divided into 12groups. The dietary Se levels were 10, 0.4 and Omg, and the dietary a-tocopherol levels were 150 and 0mg per kg diet, respectively. Alcohol-administrated groups received drinking water solution containing 10% of ethanol from the 3-weeks of experimental periods. The obtained experimental results are summarized as follows. 1. Food intake, body weight gain and food efficiency ratio were significantly lower in H-, L-and alcohol administrated groups(-A) by administrated Se and alcohol in diet. The weight of liver and spleen tended to be greater in H- and alcohol administrated groups. 2. The glutathione values in liver tend to be lower in alcohol or Vit. E administrated groups than nonadministrated groups. Also there were higher in H- and L- than C-groups, but the increasing range decreased due to administrated alcohol. The lipid peroxide values In liver were significantly higher in alcohol groups, and L- and tocopherol groups were higher values. Specially the increasing of lipid peroxide values were significantly effected by alcohol in low Se and Vit. E groups. 3. The contents of total glyceride in plasma were higher in alcohol groups, there were significantly higher values in alcohol administrated groups under low Se and Vit. E groups. The contents of total cholesterol and HDL-cholesterol In plasma were significantly higher in alcohol groups. 4. The contents of total lipid in liver were higher alcohol groups, and slightly higher values in low Se groups(L-groups) than other groups, also higher values in low Vit. E groups. Those of total glyceride in liver were significantly higher in alcohol groups, appeared highest values when alcohol was administrated in low Se and Vit. E groups. The increasing of total glyceride content was significantly effected by alcohol in low Se groups than that in C-groups.
