This study was conducted to investigate the dietary supplementation of fruiting body of Hericium erinaceus (HE) mushroom on lipid profiles of serum and histological changes of the liver in rats with high fat and cholesterol diet. Five-week old female Sprague-Dawley albino rats were divided into three groups of 8 rats each: The normal control diet (NC group), high fat and cholesterol diet (HFC group), and HFC diet supplemented with 5% fruiting powder of Hericium erinaceus (HFC+HE group). In the HFC+HE group, serum total cholesterol, low density lipoprotein, and triglyceride concentrations were significantly reduced compared with the NC group. Body weight gain of those in the HFC+HE group were lower than those in the HFC group; whereas HFC+HE had no effect on the levels of plasma albumin, creatinine, blood urea nitrogen, uric acid, glucose, and total protein. The enzyme activities related to the liver function, such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), and, alkaline phosphatase (ALP), were lower in the NC group than in the HFC group, but without significance. Feeding the mushroom increased the excretion of total lipid and cholesterol. A histopathological analysis showed that the those in the HFC group developed hepatic steatosis, whereas those in the HFC+HE group developed small fat droplet. In conclusion, these results suggest that 5% HE supplementation to HFC diet provided health benefits by acting on lowering atherogenic lipid profile in rats with high fat and cholesterol diet.

Panax ginseng is the one of best famous phytochemical plant in the world and it's various positive effects such as antioxidant, regulation of immunity are very well known. In this study, we investigated primary the cell viability and morphological change and secondary an antioxidative effect and liver function improvement of extract from Ginseng folium and stem in CCl4 intoxicated rats. The NCTC cell line were used for cell viability and sirius red staining before the animal experiment. The female Sprague-Dawley rats (90-100g) were divided into 3 groups (Normal, AC: CCl₄ treated group, GFS: CCl₄+ extract of Ginseng folium and stem treated group) and acute liver damage was developed by one time administration of CCl₄ mixture (0.5㎖/rat). The liver tissue and sera were collected and used for quantitative measurement of enzyme activity (AST, ALT, ALP, BUN), MDA and Hyp. As a result, cell viability in GFS treated group (in concentration of 3.33-33.33㎎ GFS/200㎕ medium) was 180.9-241.0% significantly and dose dependently higher than in control group. And potential state of cell growth and differentiation and no criteria of cytoplasm lysis and nucleus breaking were observed in control and GFS group. The parameters of liver function (AST and ALP) in sera of GFS group showed significantly 93% and 67.6% lower than AC group (p<0.005-0.05). And the level of ALT and BUN showed fast similar in AC group and GFS group. The concentration of MDA in liver was decreased 576.5% significantly in GFS group when compared with AC group (p<0.005). The content of Hyp in GFS group is merely lower than in AC group. In conclusion, the water extract of Ginseng folium and stem such as Ginseng radix may be possessed the antioxidative effect and improvement of liver function in CCl₄ intoxicated rats.

The purpose of this study was to investigate the biological function of ODAM and its signal transduction pathway in the steps of ameloblast differentiation and enamel mineralization. An ODAM recombinant protein was produced and stable ODAM transgenic cell lines were also established using ameloblast-lineage cells (ALCs). To verify the ODAM signal transduction pathway, BAMBI recombinant protein, an inhibitor of BMP2 and BMP receptor 1B (BMPR-1B), was treated and BMPR-1B siRNA was used to silence expression of BMPR-1B. Mineralization was augmented by the ALCs treated with the ODAM recombinant protein and the sense ODAM overexpressing cells. The ALP activity was also increased markedly in the sense ODAM overexpressing cells and the ALCs treated with ODAM recombinant protein. The inactivation of ODAM in the ALCs down-regulated the expression of BMPR-1B, whereas its expression was up-regulated markedly when ODAM was overexpressed. These results provide deeper insights into the process of ameloblast maturation and in enamel mineralization. It also suggested that ODAM augmented enamel mineralization.

Objectives: This study aimed to report a case that showed improvements in the symptoms of patients with alcoholic hepatitis without any indication of deterioration of the disease. Methods: Western medicine with Urusa tablets and Godex capsules and Korean medicine therapeutic approaches, including Shihogayonggolmoryo-tang, acupuncture, and moxibustion, were administered to a patient during the period of treatment. Blood tests were used to determine levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), AST/ALT ratio, alkaline phosphatase (ALP), gamma glutamyltransferase (GGT), total bilirubin, direct bilirubin, and total cholesterol. Fatigue was measured using the numeric rating scale (NRS), and the patient's total sleeping time was checked, daily. Results: After the combined treatment, the AST/ALT ratio and the AST, ALT, ALP, GGT, total cholesterol, and direct bilirubin levels were decreased. Through Oriental medicine for the purpose of improving symptoms, NRS of fatigue decreased from 10 to 5, and the amount of sleeping time increased from 2 to 5 hours. Conclusions: The herbal medicine had no effect on the hepatoprotective drugs such as Urusa tablets and Godex capsules used to treat alcoholic hepatitis, and no adverse reaction from the combined administration was observed. To reduce fatigue and insomnia in patients with alcoholic hepatitis, it might be helpful to combine Western medications with Korean medicine treatments, including acupuncture, moxibustion, and Shihogayonggolmoryo-tang.

The purpose of this study was designed to observe the effects of the feeding Prunus persica Batsch var. davidiana Max. extract on the concentrations of the lipids and blood glucose in the S.D. rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, triglyceride(TG), phospholipid(PL) and blood glucose in serum were significantly higher in the cholesterol administration groups (groups BCG (cholesterol+water), BCPG (cholesterol+ Prunus persica 5.0 g% extract) than those in the control group (group BG, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remarkably lower in the group BCPG than those in the group BCG. In the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Prunus persica 5.0 g% extract administration group was higher percentage than in the group BCG. The activities of aspartate aminotransferase (AST), alanine aminotransferase(ALT), lactate dehydrogenase(LDH) and alkaline phosphatase (ALP) in serum were rather lower in the Prunus persica 5.0 g% extract administration group(group BCPG) than in the cholesterol diet group(group BCG). From the above research, Prunus persica Batsch var. davidiana Max. were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic rats. And particularly, Prunus persica Batsch var. davidiana Max. was more effective therapeutic regimen for the control of metabolic derangements in adult disease.

Paralichthys olivaceus (mean length, $13.3{\pm}1.6cm$; mean weight, $25.6{\pm}3.7g$) were exposed to waterborne hexavalent chromium at different concentrations (0, 0.5, 1.0, and $2.0mg\;L^{-1}$) for 10 days. Hematological parameters such as hemoglobin and hematocrit of P. olivaceus were significantly decreased after waterborne chromium exposure. There were no significant alterations in inorganic plasma components, calcium, or magnesium after waterborne chromium exposure. Organic plasma components such as glucose and cholesterol levels were significantly increased after exposure to chromium at concentration over $1.0mg\;L^{-1}$. However, significant change in total protein was not observed. Enzymatic plasma components such as aspartate aminotransferase (AST), alanine aminotransaminase (ALT), alkaline phosphatase (ALP) levels were significantly increased after chromium exposure. Results of this study indicate that waterborne chromium exposure can cause significant alterations in hematological parameters and plasma components of P. olivaceus. Such changes in parameters could be used as reliable indicators for toxic effects of waterborne chromium exposure.
