This study was performed to investigate the effects of Cheonggukjang (traditional soybean food, CK) and Cheonggukjang added with Phellinus linteus myceria (CKP) on the lipid metabolism, growth, food intake, and food efficiency ratio(FER) in adult female rats. Sprague-Dawley rats were fed a high fat diet (control diet: 0.1% cholesterol, 10% Lard) for 4 weeks. The rats were randomly assigned to each treatment group: control, and two kinds of CK and CKP (powders of CK and CKP as dietary protein sources). After 4 weeks of experimental diet consumption, the body weights and the uterine fat pad weights of the CK and CKP diet groups were more significantly decreased than those of the control diet group. The hepatic cholesterol, triglyceride and total lipid levels were significantly lower in both the CK and CKP diet fed groups than those in the control group. The concentrations in serum triglyceride and LDL-cholesterol were significantly decreased in the CK and CKP diet groups compared to those in the control group. Fecal total lipid, moisture and wet weight excretion in the CK and CKP diet groups were more increased than those in the control group. These results showed that feeding of cheonggukjang and cheonggukjang added with Phellinus linteus myceria both the triglyceride and LDL-cholesterol in serum, as well as the triglyceride and cholesterol in the livers of the rats.

Purpose: Wilson disease is an autosomal recessive disorder which causes excessive copper accumulation in the hepatic region. So far, ATP7B gene is the only disease-causing gene of Wilson disease known to date. However, ATP7B mutations have not been found in ~15% of the patients. This study was performed to identify any causative gene in Wilson disease patients without an ATP7B mutation in either allele. Materials and Methods: The sequence of the coding regions and exon-intron boundaries of the five ATP7B-interacting genes, ATOX1, COMMD1, GLRX, DCTN4, and ZBTB16, were analyzed in the 12 patients with Wilson disease. Results: Three nonsynonymous variants including c.1084A>G (p.Thr362Ala) in the exon 12 of the DCTN4 gene were identified in the patients examined. Among these, only p.Thr362Ala was predicted as possibly damaging protein function by in silico analysis. Examination of allele frequency of c.1084A>G (p.Thr362Ala) variant in the 176 patients with Wilson disease and in the 414 normal subjects revealed that the variant was more prevalent in the Wilson disease patients (odds ratio [OR]=3.14, 95% confidence interval=1.36-7.22, P=0.0094). Conclusion: Our result suggests that c.1084A>G (p.Thr362Ala) in the ATP7B-interacting DCTN4 gene may be associated with the pathogenesis of Wilson disease.

Here we report the protective activity of cultured Acer tegmentosum cell extract against liver damage in rat intentionally instigated by D-galactosamine. Local fat degeneration and infiltration of inflammatory cells were significantly decreased in cultured A. tegmentosum cell extract administered rat. In addition, acutely increased AST, ALT, LDH, ALP activities and lipid peroxidation and lipid content by liver damage were recovered in experimental rat administrated with A. tegmentosum extract. These results showed that cultured A. tegmentosum cell extract has a role in blood enzyme activation and lipid content restoration within damaged rat liver tissues. Moreover expression rate of TNF-α which accelerates inflammation and induces tissue damage and necrosis was significantly decreased. Also activities of antioxidant enzymes were more effectively upregulated comparing to those of the control group induced hepatotoxicity. All data that cultured A. tegmentosum cell extract has a preventive role against liver damages such as inflammation, tissue necrosis in rats by improving activities of blood enzymes, antioxidant enzymes and modulating expression of inflammation factor, suggest that cultured Acer tegmentosum cell extract is an effective medicinal resource for restoration of hepatotoxicity.

Effects of 5 and 10% dietary supplement tablets containing green tea, buckwheat, and grape leaf extracts on atherosclerosis, and plasma and hepatic lipid compositions in hamsters fed antherogenic diet [modified AIN-76A containing 10% coconut oil (w/w), 0.05% cholesterol] were examined. Compared to atherogenic diet only groups, addition of supplement to atherogenic diet-fed group significantly down-regulated triglyceride and total cholesterol levels in plasma and liver. F1B hamsters fed atherogenic diet had greater foam cell accumulation compared to control and those fed atherogenic diet with addition of supplement. Lipid metabolisms of plasma and liver increased with addition of supplement dose-dependently, whereas aortic lipid accumulation decreased. These results indicate tablets supplemented with green tea, buckwheat, and grape leaf extracts have potential to prevent cardiovascular diseases in golden Syrian hamsters.

These studies were carried out to investigate the effects of Puerariae radix catechins(PRC) administration on the biochemical parameters of liver function in liver of carbon tetrachloride(CCl4)-treated rats. Thirty six healthy Sprague-Dawley rats weighing about 120g were used for this experiment and divided intot he following 3 groups : normal control group(NCON), $CCl_4$ control group(CCON), PRC treated group(PRC). Fifty percent $CCl_4$ in oil was administered(I.P.) by 2ml per kg body weight two times a week for 3 weeks. PRC treated groups were administered orally at the leaves of 1% per day in distilled water for 8 weeks. Lipid hydroperoxides were analyzed by using chemiluminescence-high performance liquid chromatography(CL-HPLC) method as a phosphatidylcholine hydroperoxide value(PCOOH) in liver tissues. $CCl_4$ treatment significantly(p<0.05) resulted in an increase in GPT & GOT activities and liver hydroperoxide values comparing with those of the untreated control, while administration of PRC to the $CCl_4-treated$ rats significantly(p<0.001) decreased GPT & GOT activities and liver hydroperoxide value. Their ultrastructual changes of hepatocellular organelles were shown to clarify the morphologic nature of protective effects of PRC on hepatocytic injuries. $CCl_4$ treatment observed to change the ultrastructual nature of outer membrane of hepatocytes. However, the hepatic changes on PRC treatment to $CCl_4$ group was not found. PRC administration may inhibit the formatiion of liver lipid hydroperoxides in vivo and were very effective in recovering the liver function in $CCl_4-treated$ rats.

The purpose of this study is to evaluate the effect of Injinchunggantang-derivative on proliferation of hepatocyte in rats. Cell viability is studied by MTI assay. The gene related to cell replication such as p53, waf1, bcl-2 and $bcl-_{X_L}$ is quantitized by quantitative RT-PCR and the proteins coded by these genes are studied by Western blotting. The results are as follows. 1. The hepatocytes cultured in medium with lnjinchunggantang-derivative showed better viability compared with control grroup in MTI assay, and the hepatocytes cultured in medium with the Injinchunggantang-derivative-and-ethanol-mixed group showed better viability than the hepatocytes cultrued in 10% ethanol culture medium(control group), noting that Injinchunggantang-derivative has protective effect on hepatocyte injury. There was no dose- and time-dependence. 2. In quantitative RT-PCR, i) Bel-2 gene increased significantly both in Injinchunggantang-derivative group and in Injinchunggantang-derivative-and-ethanol-mixed group, while it showed no significant increase or decrease in other group. ii) $Bcl-_{X_L}$ gene increased significantly in Injinchunggantang-derivative group as well as in Injinchunggantang-deri vative-and-ethanol -mixed group. iii) P53 gene showed no significant increase or decrease in hepatocytes cultured in medium with 10% ethanol and in hepatocytes cultured in medium with Injinchunggantang-derivative-and-ethanol-mixed group, suggesting that 10% ethanol induced cell toxicity, thus increased p53 gene expression. iv) Wafl gene showed no significant increase or decrease in hepatocytes cutured in medium with Injinchtrnggantang-derivative, while increased in hepatocytes cultured in medium with 10% ethanol and in hepatocytes cultured in medium with Injinchtrnggantang-derivative-andethanol-mixed group, suggesting that 10% ethanol induced cell toxicity increased wafl gene expression. 3. In the study on protein by western blotting, the band of bcl-2 and $bcl-_{X_L}$ were widened in Injinchtrnggantang-derivative group. Especially the amount of $bcl-_{X_L}$ increased significantly compared with other groups. But in the study on p53 and wafl, there was no significant difference among those groups. Above study shows that Injinchunggantang-derivative has good effect on cell viability and that the genes resistant to cell death such as bcl-2 and $bcl-_{X_L}$ are induced by Injinchunggantang-derivative to resist to cell death by toxic agent And this is reconfirmed in protein study using' western blotting: These results suggest that Injinchunggantang-derivative has inhibitory effect on cell death as well as protective effect on hepatocyte. Therefore this prescription is recommended in various liver diseases such as chronic liver disease and-induced hepatic injury.

The purpose of the present study was to investigate the mechanism of metabolic partitioning between oxidization and esterification of liver fatty acids synthesized and secreted by the liver from egg yolk-fed laboratory rats. Animals were divided into four groups and orally administered egg yolk daily for 30 days: CON (control group, 1.0 g of saline solution), T1 (1.0 g of pork belly oil), T2 (1.0 g of egg yolk), and T3 (1.0 g of pork belly oil and 1.0 g of egg yolk, alternatively each week). The accumulation rate of [¹⁴C]-labelled lipid in liver was lowest in T2 among all treatments (P<0.05). Phospholipid secretion was higher in T2 than other treatments (P<0.05). The triglycerol secretion was highest in T1 and higher in the order of CON, T3, and T2 (P<0.05). Metabolic partitioning rate of phospholipid from total glycerolipid was highest in T2, followed by T3, CON and T1 (P<0.05). The ¹⁴CO₂ production from total glycerolipid was the highest in T2 and showed a high oxidation rate compared to CON, T1, and T3 (P<0.05). Metabolic partitioning of glycerolipid from the liver decreased in triglycerol of T2 compared to CON, T1, and T3, whereas phospholipids of T2 increased (P<0.05).

To compare the hypolipidemic effects of perilla oil with different kinds of dietary fat and oil forty eight 20 days old male Wistar rats were fed one of the following diets for 4 weeks: basal diet for control containing 9.4 w/w% corn oil(CO), 9.4 w/w% beef tallow (BO), 9.4 w/w% perilla oil(PO) and 4.7 w/w% beef tallow plus 4.7% perilla oil(BP). The amount of diet consumed and body weight gain rate were not significantly different among the four dietary groups. The levels of plasma triglyceride and total cholesterol in PO group were significantly lower than those of BO and BP groups. PO group also had significantly lower LDL-cholesterol in BP group were than other groups. The levels of plasma triglyceride tatal-cholesterol and LDL-cholesterol in BP group were significantly lower than those in BO group by 9.2%, 10.3% and 18.6% respectively. Plasma glutamic oxaloacetic transferase and alkaline phosphatase activities and uric acid levels in PO group were significantly higher than other groups and were somewhat beyond the normal levels. These findings showed that perilla oil with hypolicpidemic effects could have some adverse effects on hepatic and other organic functions in rats.

This study was purposed to compare the activity of alcohol dehydrogenase and antioxidative effects of several plant extracts in the alcohol-treated rat liver. Sprague-Dawley rat weighing about 200 g were divided into the following 6 groups : normal, alcohol group and 4 different plant extracts administrated groups(Soybean sprout, Pine needle, Lentinus edodes, acanthopanacis cortex). Each plant extract was administrated orally by 200mg/kg b.w./day for 8 days before the alcohol treatment (5 g of 30% alcohol /kg b.w. by i.p.injection). All rats were sacrificed at 90 min after the alcohol treatment. The alcohol concentrations in serum of Soybean sprout and pine needle group were significantly lower than the Lentinus edodes and Acanthopanacis cortex group. The activity of alcohol dehydrogenase in the hepatic cytosol of Soybean sprout and Pine needle group was also significantly higher than the alcohol and the other groups However, the activity of catalase seemed not to be affected, although the extract groups showed slightly higher activities of catalase than the alcohol group. These results may indicate that the extracts of Soybean sprout and Pine needle were relatvely effective on the alcohol degradation. the activity of blutathione-peroxidase and lipid peroxidaton of all of the extract groups were significantly lower than the activity of alcohol group. These results can suggest that all of the use plant extracts more or less have an antioxidative effect on the alcohol-induced oxidation and especially, extracts of Soybean sprout and Pine needle have an stimulating effect on the alcohol absorption and degradation.

The effects of Okcheonsan powder on the body weights, the organ weights, the blood glucose level, the lipid and protein concentrations of serum and liver in diabetic rats were studied. Female rats (Sprague-Dawley, mean weight 313.6$\pm$18.5 g) were randomly assigned to one normal and two diabetic groups. They were fed experimental diets for 5 weeks. The diabetic groups were divided into the diabetic control (D-control group) and 3% Ok-cheonsan groups (D-Okcheonsan group). Rats were injected with streptozotocin intraperitoneally to induce diabetes. The body weights, the concentrations of total lipid and triglyceride of liver, the concentrations of total protein and albumin of serum in tole D-control and the D-Okcheonsan groups were significantly decreased compared with those in the normal group. The pancreatic weight in the D-control group was significantly more increased than that in the D-Okcheonsan group, but in the D-Okcheonsan group it was similar to that in the normal group. The fasting blood glucose levels and the atherogenic index in all the diabetic groups were significantly higher than those in the normal group. The concentrations of triglyceride, total cholesterol and LDL-cholesterol of serum, and the cholesterol of fiver in the D-Okcheonsan group were significantly lower than those in the D-control group. The concentration of HDL-cholesterol and HDL-cholestrol/total cholesterol ratio of serum were similar to those in all the groups. The concentrations of phospholipid of serum and liver in the D-Okcheonsan group were significantly decreased compared with those of the normal group, In conclusion, the Okcheonsan powder feeding could decrease the pancreatic weight, the concentrations of the triglyceride, the total cholesterol and LDL-cholesterol of serum, and the cholesterol of liver in the diabetic rats. But the concentrations of the blood glucose, the hepatic triglyceride and the atherogenic index seems to be not affected by it.
