  • The purpose of this study was to observe the effects of the polysaccharide (GLP) obtained from the liquid cultured Ganoderma lucidum on the lipidperoxidation in a rat liver microsome and hepatotoxicity in the primary cultured rat hepatocytes. It is well known that the polysaccharide of Ganoderma lucidum exhibits hepatoprotective activity, antitumor activity etc., which many suggest a relationship to lipidperoxidation. The effect of GLP on $CCl_4-$ and galactosamineintoxicated cytotoxicity in the primary cultured rat hepatocytes were reduced the GPT value. In order to the estimate the effects of anti-lipidperoxidation of the polysaccharide, enzymatic and nonenzymatic reaction assays were performed, in vitro, in the rat liver microsome. An enzymatic lipidperoxidation reaction by $ADP+FeCl_3+NADPH$ and $CCl_4+NADPH$, GLP (1 mg/mL) inhibited 77.4% and 39.4%, respectively, and the nonenzymatic reaction displayed a 97.4% strongly inhibition. In the enzymatic and nonenzymatic inducers treated with GLP, the formation of malondialdehyde (MDA) progressively decreased by raising the GLP concentration. These results suggest that the anti-lipidperoxidation and radical scavenging activity of GLP may play an important part in the liver protection action.

  • A great deal of attention has been directed recently at the roles played by lipidperoxides in the mediation of pathogenesis and complications of various disease. In view of the strong inhibitory activity of Brazilin on the lipidperoxidation, we examined the effect of Brazilin on the lipidperoxidation in diabetic states. Brazilin inhibited the lipidperoxidation of liver mitochondrial and microsomal fraction in alloxan-induced diabetic ICR mice in the dose and time dependent manner. In the light of the present results, further elucidation of the inhibitory activities of Brazilin on the liver and blood plasma is warrented.

  • The purpose of this study was to observe the effects of the polysaccharide(G009) obtained from liquid cultured Ganoderma lucidum IY009 on the lipidperoxidation in rat liver microsome. It is well known that the polysaccharide of G. lucidum have the hepatoprotective activity, antitumor activity etc., which was thought to have the relationship to anti-lipidperoxidation. In order to the estimate the effects of anti-lipidperoxidation of the polysaccharide obtained from G. lucidum IY009, enzymatic and nonenzymatic reaction were performed, in vitro, in rat liver microsome. In enzymatic lipid peroxidation reaction by ADP/FeCl$_3$/NADPH and $CCl_4$/NADPH, G009(1mg/ml) inhibited 77.4%, 39.4%, respectively, and the nonenzymatic reaction strongly exhibited 97.4% inhibition. And also, in enzymatic and nonenzymatic inducers treated with G009, the formation of MDA was progressively greater decreased by raising G009 concentration. These results suggest that anti-lipidperoxidation by G009 treatment may be play an important part in liver protection action.

  • This major sites of liquidperoxidation-damage within the cell are at biomembrances, especially those of subcellular organells such as mitochondria and microsomes whose membranes contain relatively large amount of polyunsaturated fatty acids. Mitochondria are the power plants of eukaryotic cells. Hence their damage by liquid peroxidation can profoundly affect cellular function.

  • It is well known that lipidperoxide, formed in vivo, induced the denaturation of enzyme and destruction of cell membrane to acute injury of tissue. Aralia elata have physiological activates, the improvement of lipid metabolism, antidiabetic activity etc., which was thought to have the relationship to lipid peroxidation. The anti-lipidperoxidative effect of Aralia elata have not yet established. In this study, we examined the anti-lipidperoxidative effects of Aralia elata (Butanol fraction) on CCI$_{4}$ induced lipidperoxidation in rats, and elucidated the anti-lipidperoxidative mechanism. In rat liver homogenate intoxicated with CCI$_{4}$ (0.5 ml/100g), BuOH fraction of Aralia elata (80 mg/Kg/day) exhibited 85.41% anti-lipidperoxidative effect but in serum 69.63% inhibitory effects, respectively. In mitochondrial and microsomal fraction showed inhibition of 55.85% and 69.30%, respectively. In order to elucidate the mechanism of anti-lipidperoxidation effects of Aralia elata, enzymatic (NADPH dependent) and non-enzymatic (Ascorbic acid catalyzed) reaction, in vitro, were performed. In enzymatic reation, Aralia elata exhibited 59.43% anti-lipidperoxidation effects, but in non-enzymatic reaction exhibited 43.27% inhibition. Therefore, it is noteworthy that antioxidative power of them may mainly results from the inhibition by enzymatic reaction.

  • The antilipidperoxidative and hepatopreventive effects of Houttuynia cordata extract(HCE) were investigated at the level of liver homogenates and serum of SD rats intoxicated EtOH(3g/kg for 3days). We measured MDA(malondialdehyde) in the live. homogenate, AST(1-aspartate-2-oxoglutarate aminotransferase) and ALT( 1-alanine-2-oxoglutarate aminotransferse) in the serum. The analysis of the measurement indicated that HCE reduced MDA, ALT and AST significantly and their reduction was in relation to dose dependence. In rat liver homogenate intoxicated with EtOH, HCE treatment group inhibited lipidperoxidation by 50-75%. In rat serum intoxicated EtOH, HCE inhibited AST and ALT by 40-70%.

  • In oriental medicine, Artemisiae asiatica (AA) has been used as analgesic, antiinflammatory agent, and coagulatory agent. Furthermore, eupatilin, a kind of flavonoids, is known as the active principle component of AA. This study was undertaken to determine the gastric antiulceration of AA and to elucidate its mechanism. AA showed the inhibitory effect on gastric ulceration induced by EtOH/HCl and aspirin. To elucidate its mechanism, the effect of AA on lipidperoxide level in gastric mucosa, microsome lipidperoxidation, iron -dependent lipidperoxidation, and neutrophil activation were examined. It is suggested that the antiperoxidative and antineutrophil activity of AA play important roles as a possible mechanism. These results suggest that AA might have gastric antiulceration activity due to antilipidperoxdative and antineutrophil activity.

  • Panax ginseng C.A. Meyer (Panax ginseng) has been used for several thousand years to prolong longevity in Asian countries. Ginsenosides are the most active components isolated from ginseng and belong to damarane saponin which are separated into protopanaxadiol and protopanaxtriol. To evaluate the complex effect of ginsenoside in apo E null mice, ginseng extract were intraperioneally (i.p.) injected and provided high-cholesterol diet for 12 weeks. Ginseng extract came from were i.p. injected with dose of 100 mg/kg/day for 4 weeks in the last experimental duration. Ginseng extract used experiment was abundant Rb1, Rc, Re, and Rg1 and PD:PT ratio was 1.2. The high-cholesterol diet induced liver damage was significantly reduced by ginseng extract. Results from plasma lipid profiles and atherogenic index were improved by ginseng extracts. The GE group significantly decreased plasma TG and TC by 73% and 61% compared to apo E (-/-) group. Also ginseng extract tend to decrease lipid profiles and lipidperoxidation contents in liver and heart. Ginseng extract with an abundant amount of Rg1 significantly suppressed the apoptosis induction of cardiac tissue. In conclusion, ginseng extract (PD:PT = 1) was improved lipid profiles and anti-oxidant effects.

  • The antilipidperoxidative effects of Brazilin and Hematoxylin were investigated at the levels of liver~total homogenates, -microsomal fraction, -mitochondrial fraction and the sera of SD-rats intoxicated with $CCl_4$ and ethanol. Both natural dyes markedly inhibited the lipidperoxidation induced by $CCl_4$ and ethanol. Brazilin and Hematoxylin showed the inhibitory effects on the both enzymatic (NADPH-dependent) and nonenzymatic (Ascorbate-induced) lipidperoxidation pathways. but it is supposed that the antilipidperoxidative powers of them mainly result from the inhibition of the nonenzymatic lipidperoxidation.
