  • Objectives : Hemistepta lyrata Bunge (Bunge) is a wild herb that has been used for managing fever and wound in Korean Traditional Medicine. The present study explored the effects of H. lyrata extract on liver X receptor (LXR) α-dependent lipogenic genes in hepatocyte-derived cells. Methods : After HepG2 cells or Huh7 cells were pre-treated with 1-10 ㎍/mL of H. lyrata extract or its fractionated extract for 0.5 h, the cells were subsequently exposed to LXR ligand for 6-24 h. Cell viability, LXR response element (LXRE)-driven luciferase activity, sterol regulatory element binding protein-response element (SREBP-RE)-driven luciferase activity, SREBP-1c expression, and mRNA levels of LXRα and its-dependent target genes were determined. In addition, LC-MS/MS analysis was conducted to explore major compounds in H. lyrata-chloroform fractionated extract #4 (HL-CF4). Results : Of various H. lyrata extracts tested, chloroform extract and its fractionated extract #4, HL-CF4, significantly decreased T0901317-mediated SREBP-1c expression. In addition, HL-CF4 significantly reduced LXRE atransactivation and LXRα mRNA expression without any cytotoxicity. Moreover, HL-CF4 prevented the SREBP-RE-driven luciferase activity and mRNA levels of fatty acid synthase and stearoyl-CoA desaturase-1 induced by T0901317. Results from LC-MS/MS analysis at positive/negative mode indicated that HL-CF4 contained several compounds showing m/z 197.1176 (C11H17O3), 693.2913/227.1069 (C38H45O12/C15H15O2), 203.1797 (C15H23), 181.1225 (C11H17O2), 591.2957 (C35H43O8), 379.1040 (C18H19O9), 409.1509 (C20H25O9), 309.1348 (C16H21O6), 391.1404 (C20H23O8), and 669.2924/389.1248 (C36H45O12/C20H21O8). Conclusion : Based on its inhibition of the LXRα-dependent signaling pathway, H. lyrata chloroform extract and HL-CF4 have prophylactic potentials for managing non-alcoholic fatty liver.

  • This study was conducted to investigate the effect of crude saponin of red ginseng and aqueous extracts from several medicinal herbs on the activity of alcohol dehydrogenase(ADH) and aldehyde dehydrogenase(ALDH) in alcohol metabolism. In order to develop a liquid phase product a model product was prepared using functional plants. In case of red ginseng crude saponin, and some medicinal herbs(Puerariae radix, the flower of Puerariae lobata, the fruits of Hovenia dulcis Thunb., Morus alba L.) the relative activity of ADH was significantly increased, which was from 104~114%. The relative activity of ALDH was also significantly increased in the cases of the fruits of Hovenia duicis Thunb., Morus alba L. which was from 102∼106%. To improve of soju flavours by addition of liquid phase product, it is prepared three samples added a given content (0.28%) of chik, ssanghwa and kyungokgo flavour. The total acceptability test showed significant differences among three samples, and it is observed that the sample added ssanghwa flavour get the best grade. As the second acceptability test, the preference of ssanghwa flavoured sample, sample without flavour and a similar product in market was compared. There was no significant difference among three samples.

  • This study was performed to evaluate the possible production of a functional beverage derived from abalone and with several plants (AP). Five types of AP composites were prepared having different medicinal plant compositions (AP- I : abalone, garlic, jujube, Chinese matrimony fruit, dried orange peel, licorice root, zinger, honey; AP- II: abalone, garlic, black bean, Chinese matrimony fruit, cornus fruit, licorice root, zinger, honey; AP-III : abalone, jujube, arrow root, milk vetch, dried orange peel, licorice root, zinger, honey; AP-N: abalone, black bean, arrow root, milk vetch, cornus fruit, liquorice root, zinger, honey; AP-V : abalone, garlic, Chinese matrimony fruit, milk vetch, licorice root, zinger, honey). In vitro analysis were performed to examine the antioxidant contents and alcohol dehydrogenase activities of the composites. AP- II had the highest total phenol contents ($28.55{\pm}1.56\;mg/l00\;g$), and AP- V the highest level of flavonoids ($47.61{\pm}1.58\;mg/l00\;g$). At $78.89{\pm}0.16%$, AP- V displayed the strongest electron donating ability followed by AP-II($57.99{\pm}0.21%$) and API ($37.66{\pm}0.20%$). Reducing power was also significantly higher in AP- V. The Hydroxyl radical scavenging and SOD-like activities of all composites were less than 15% and 20%, respectively. At 12.5% alcohol concentration, ADH activity ranged from $114.47{\pm}2.18{\sim}121.39{\pm}4.36%$ and ALDH activity ranged from $100.04{\pm}2.90{\sim}129.54{\pm}4.80%$; AP- I , AP- II, and AP- Vin 12.5% of alcoholic concentration. The composites of AP- I , AP- II, and AP- V, all containing garlic and Chinese matrimony fruit, were significantly stronger than AP-III and AP-N. Finally, also at 12.5% alcoholic concentration, the ALDH activity of AP- V was higher than its ADH activity.

  • Rubus crataegifolius (RC) is a traditional Asian medicinal plant belonging to the Rosaceae family. The fruits of RC are known to prevent adult diseases through antioxidants. In this study, the effects of RC extract (RCex) on obesity and nonalcoholic fatty liver disease (NAFLD) were evaluated in animal models. Twenty-eight male C57BL/6J mice were induced to become obese for 8 weeks and then the extract was orally administered for 8 weeks. RCex reduced body weight, adipose tissue, liver weight. RCex improved biochemical biomarkers including lipid metabolism (alanine aminotransferase (ALT), aspartate aminotransferase (AST), plasma triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL) cholesterol and low-density lipoprotein (LDL) cholesterol). The activation of AMP-activated protein kinase (AMPK) reduced the expression of adipogenesis genes (liver × receptor (LXR), sterol regulatory element-binding protein-1c (SREBP-1c), fatty acid synthesis (FAS), acetyl-CoA carboxylase 1 (ACC1) and the effect of enhancing carnitine palmitoyltransferase (CPT) activity by RCex was verified. RCex also influence on plasma production of hormones (adiponectin & leptin) related on energy expenditure and metabolism. In addition, we confirmed that RCex improved glucose intolerance in HFD-induced obese rats. RCex was first demonstrated to have anti-obesity as well as anti-NAFLD effects by regulating fatty acid oxidation and fatty acid synthesis by phosphorylation of AMPK. This suggests that RCex could be a good supplement for the prevention of obesity and related NAFLD.

  • The concentration of amino acids, total nitrogen, trehalose, lipids and the activities of respiratory, acid$\cdot$alkaline phosphatase, glutamic oxalozcetic transaminase and glutamic pyruvic transaminase during larval stage in Pine leaf gall midge, Thecodiplosis janensis Uchi. et Inouye were measured using Paper chromatographic method, micro-Kjeldahl method, Thin layer chromatographic method, Warburg's manometric method, Bessey-Lowry method and Reitman-Frankel method, respectively. Healthy specimens )yore chosen as samples of each larval stages; alrva in gall and larva in soil. Amino acids present in the alcoholic extracts were alanine, glutamic acid, glycine, histidine, methionine, proline, threonine, tryptophan and valine. The total nitrogen concentration reached to 31.348mg/g during the larva in gall and the larval stage in soil of the value was decreased to 29.027mg/g. The hemolymph sugar, trehalose value for larva in soil was about two times of the value for larva in gall. Total lipid, phospholipid,monoacylglycerol, triacylglycerol, sterol, free fatty acid and ester cholesterol were identified at larval stages in gall and soil. Triacylglycerol concentration reached high level in contrast with other lipid contents during larvae in gall and larva in soil. Free fatty acid, sterol except decreased lipids during larval stage in soil. Endogenous respiration, succinate of respiratory activities decreased at larval stage in soil compare with larva in gall. The activities of acid phosphatase decreased larval stage in soil but the activities of alkaline phosphatase increased remarkably. The activities of glutamic oxaloacetic transaminase and glutamic pyruvic transaminase reached high level of the larva in gall.

  • The present study was investigated effect of each water extract from Pueraria flos (PF) and Pueraria radix (PR) on serum several biomarkers in ethanol-treated rats. Male Sprague-Dawley rats were randomly divided into six groups: Normal (None-treated group); Ethanol (only ethanol-treated group); EPF I (ethanol-treated, supplemented group); EPR (ethanol-treated, PF II-supplemented group); EPR I (ethanol-treated, PR I-supplemented group) ; EPR (ethanoltreated, PR II-supplemented grou). Five groups of male Sprague-Dawley rats were orally administered 25% ethanol (5 g/kg body weight/day) and sacrified 5 weeks post treatment. Aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and ${\gamma}-glutamyl$ transpeptidase activities were significiantly lowered by feeding of PF or PR than those of only ethanol-treated group. Whereas serum glucoseand liver glycogen contents were significantly decreased (p<0.05) by ethanol administration and increased decreased (p<0.05) by PF or PR supplement. This results indicate that Pueraria flos and radix water extract supplement improves alcoholic disorder.

  • The effect of alcoholic extract of Anthocephalus (A.) Cadamba Roxb. was evaluated in experimental models of pain and ulcer. Hot tail flick test, hot plate test and acetic acid induced writhing test were employed for evaluating the peripheral as well as central analgesic mechanism exerted by the extracts. Gastroprotective activity was examined by HCl and ethanol induced gastric damage test. Test group received crude extract 500 mg/kg showed maximum time needed for the response against thermal stimuli (6.26 ${\pm}$ 0.439 s) which is comparable to diclofenac sodium (6.56 ${\pm}$ 0.381 s) in hot tail flick method. These experimental results also followed the experimental results of hot plate test where crude extract 500 mg/kg showed maximum time needed for the response against thermal stimuli (4.74 ${\pm}$ 0.234 s) which is comparable to diclofenac sodium (5.58 ${\pm}$ 0.585 s). The crude extract at 500 and 250 mg/kg showed significant reduction in acetic acid induced writhing in mice with a maximum effect of 68.026% reduction at 500 mg/kg dose which is comparable to standard diclofenac sodium (79.93%). In gastroprotective study the extract of A. Cadamba (250 and 500 mg/kg) significantly inhibited ulceration induced by both HCl and ethanol dose dependently. Results of the study suggest that the extract possesses both analgesic and gastroprotective activity on mice.

  • In order to study the rate control step in the protein metabolic course of the chlorophyll formation, the transaminase activities which are obtained freely in the extracts of cotyledons of germinating peas at the light and the dark places, are measured in Beckman mopel D.U, spectrophoto meter at 490 mu. In this case, of two enzymatic reaction products; oxalacetic acid and pyruvic acid, the former is converted to pyruvic acid by aniline citrate and after each pyruvate phenyl hydrazones are extracted by toluenes: when this is treated with strong alcoholic alkali, a colored hydrazone is formed and it is measured by above apparatus. The estimated G.O.T. and G.P.T. in the germinated cotyledons at dark and light places considerably differ in their activities; G.O.T. and G.P.T. activities which are formed at the light are more increased than at the dark and also they differ in their rates through germination, though G.O.T. activity increment is smoothly but that of G.P.T. is more sharply, and they are considered to be directly affected to the chlorophyll formation and indirectly to the growth. G.O.T. and G.P.T. in each fractions of cell in the cotyledons should be formed by dissociation of zymogens in the microsomal fractions and it seems to promoted by light. In the formation of the chlorophyll, the protein metabolism occurred mainly in the microsomal fractions and the rate determining step is found at the point where the zymogene that is able to produce G.P.T. is activated, and this activation is promoted by light as noted above.

  • This study had been done for the investigation of the effect of Vitis vinifera extract (VV), Schisandra chinensis extract (SC), Taraxacum officinale extract (TO), Gardeniajasminoides extract (GJ), Angelica acutiloba extract (AA) and Paeonia japonica extract (PJ) on fatty liver and hepatotoxicity which was induced by Lieber-DeCarli ethanol liquid diet. Male Sprague-Dawley rats were randomly divided into eight groups: ethanol diet (ED), normal diet (ND), ED+VV (100mg/kg), ED+SC, ED+TO, ED+GJ, ED+AA, and ED+PJ (300mg/kg/day). Rats fed liquid diets for 6 weeks showed remarkable increase in serum and hepatic lipids indicating the onset of alcoholic fatty liver. The increasing levels of GPT, ALP activities in serum were observed in the groups fed with alcohol-containing diets compared to those of the ND group. The VV, SC, TO, GJ, AA and PJ groups were decreased the levels of triglyceride, free fatty acid and total cholesterol in serum and liver and GPT, ALP activities in serum. Therefore, they can be utiliaed as a health functional food or new drug candidate for fatty liver and hepatotoxicity which was induced by chronic alcohol consumption.

  • In this study, we investigated the hepatoprotective effects of garlic extracts fermented with Lactobacillus plantarum on alcohol-induced fatty liver damage in C57BL/6J mice. The weight of liver tissue of the lactic acid-fermented garlic extract (LAFGE) diet groups decreased in a dose-dependent manner compared to that of the normal diet group. The activities of typical serum enzymes such as ALT, AST, and ALP were low in the LAFGE 200 mg/kg administered group. The LAFGE 200 mg/kg administered group significantly decreased values of TBIL and DBIL, which are an important index of liver damage. LAFGE also ameliorated alcohol-induced hepatic lipid accumulation in histological analysis dose-dependently. In addition, total GSH and reduced GSH levels in LAFGE-treated groups were gradually recovered up to normal levels. The present study revealed that LAFGE improved unique tastes and odors of raw garlic through lactic acid fermentation technology and thus could be a commercially potential material for hepatoprotective functional foods against alcoholic fatty liver.
