Objectives Coptidis Rhizoma and Glycyrrhiza Uralensis are herbs that treat obesity and dampness-phlegm. The aim of this study is to investigate the efficacy of Coptidis Rhizoma and Glycyrrhiza Uralensis on lipid deposition with nonalcoholic fatty liver disease (NAFLD). Methods Male 6-week-old C57BL/6 male mice were divided into three groups: control group (Ctrl), high fat diet group (HFF), and high fat diet with Coptidis Rhizoma and Glycyrrhiza Uralensis extract administration group (CGT). Each 10 mice were allocated to each group (total of 30 mice). All mice were allowed to eat fat rich diet freely throughout the experiment. To examine the effect of Coptidis Rhizoma and Glycyrrhiza Uralensis, we observed weight changes, total cholesterol and glucose levels, lipid blot distributions, PGC-1, p-$I{\kappa}B$, and p-JNK. Results Body weights for all mice were measured and analyzed the difference between the groups. Weight gain was significantly lower in CGT group than the HFF group. Total cholesterol and glucose levels were significantly lower in CGT group. The distribution of lipid blots and positive reaction of PGC-1 were significantly lower in CGT group. The positive reaction of p-$I{\kappa}B$ in hepatic tissues was significantly lower in CGT group. The positive reaction of p-JNK in hepatic tissues was significantly lower in CGT group. Conclusions Coptidis Rhizoma and Glycyrrhiza Uralensis have the effect of improving non - alcoholic fatty liver induced insulin resistance through regulation of lipid metabolism.

This study was designed to elucidate the lipid and its fatty acid composition in various tissues of cat fish, Parasilurus asotus. The free lipid contents in meat, skin and viscera were 5.62%, 26.34% and 19.27%, whereas the bound lipid contents in those tissues were 2.34%, 2.30% and 19.27%, respectively. The neutral lipid contents in free lipid were 5 times higher than those in bound lipid, while the phospholipid contents in bound lipid were 4 times higher than those in free lipid. The neutral lipid was mainly composed of triglyceride (79.84%-99.86%) in free lipid, and esterified sterol & hydrocarbon (55.12-64.33%) in bound lipid. The phospholipid was mainly composed of phosphatidyl choline (52.38-69.98%) and phosphatidyl ethanolamine (24.09-40.48%) in free lipid, and phosphatidyl choline (53.03-58.54%) and phosphatidyl ethamolamine (13.80-19.23%) in bound lipid. The major fatty acids of polar lipid in free and bound lipids were C16:0 (28.37%, 21.99%), C18:1 (12.01%, 11.52%), C18:2 (17.93%, 14.12%) and C22:6 (17.22%, 20.63%), and those of nonpolar lipid in free and bound lipids were C16:0 (14.81%, 18.94%), C18: 1 (25.93%, 10.89%) and C22:6 (9.95%,23.44%), respectively. The total essential fatty acid (TEFA) content in skin was slightly higher than that in meat. In both polar and nonpolar lipids in meat ${\omega}3-HUFA$ contents of polar lipid were 1.5-2.0 times higher than nonpolar lipid and also ${\omega}3-HUFA$ content of bound lipid was slightly higher than that of free lipid. There were significant differences in the lipid classification and its fatty acid composition between free and bound lipids and/or in various tissues.

The distribution of the secretory ducts, fine structures of the secretory epithelial cells, and the ingredients of the metaplasmic inclusions were studied at light and electron microscopical levels in seeds, stems, leaves, and roots of ginseng. The secretory ducts occurred in the hypocotyl of the embryo, in the cortex of the roots, and also both inside and outside of each vascular bundle in the stems and leaves. Especially, it is considered that the circular layers of the secretory ducts in roots may represent their ages. The epithelial cell has well developed nucleolus, mitochondria and smooth endoplasmic reticulum. Sudanophyl and osmiophilic inclusions were found in the epithelial cytoplasm and duct lumen. But these inclusions were not observed when extracted with pyridin or alcohol. In contrast to the lumen with red color, the epithelial cells were blue in color as stained with nile blue, suggesting that the former inclusions are neutral lipid while the latter are acidic lipid. The electron density of the cell inclusions was quite high as fixed with osmium tetroxide, indicating that most of these secretory materials seem to be unsaturated lipid. Therefore, since ginseng secretory ducts are closely associated with the lipid metabolism, it should be called lipid canal or lipid duct.

Hepatic tissues of ICR mouse were intraperitoneally injeced with Colpomenia bullosa(CB) Extract after Triton WR-1339(TX) injection were observed to investigate the antihyperlipermic effect of CB extract for hyperlipidemic hepatic tissue caused by destruction of lipid metabolism. The hepatic tissues were obtained at hour-24, 48, and 72 after TX injection with CB extract treatment. And then these specimen were fixed in 10% neutral buffer solution and were cryocut. The tissue stained by H&E for general morphology and sudan black B for lipid distribution. The increase of hepatocyte havinig meshlike cytoplasm were shown in all hepatic lobules after TX injection and the hepatic plates were disappeared in the region of meshlike hepatocyte aggregation. But the hepatocyte having meshlike cytoplasm were disappeared and hapatic plate were rearranged in CB extract injected mouse. The number of blue black colored lipid drop in hepatic cytoplasm of mouse injected with TX were increased and the size of lipid drop were enlarged. But the number of lipid drop in hepatic cytoplasm of mouse treated CB extract were decreased and the size of lipid drop were diminished. As results indicated that the accumulation of lipid drop caused by TX injection were mitigated by the antihyperlipidermic effect of CB extract.

The purpose of this study is to investigated the mechanism of pharmacological action of local anesthetic and provide the basic information about the development of new effective local anesthetics. Fluorescent probe techniques were used to evaluate the effect of lidocaine HCl on the physical properties (transbilayer asymmetric lateral and rotational mobility, annular lipid fluidity and protein distribution) of synaptosomal plasma membrane vesicles (SPMV) isolated from bovine cerebral cortex, and liposomes of total lipids (SPMVTL) and phospholipids (SPMVPL) extracted from the SPMV. An experimental procedure was used based on selective quenching of 1,3-di(1-pyrenyl)propane (Py-3-Py) and 1,6-diphenyl-1,3,5-hexatriene (DPH) by trinitrophenyl groups, and radiationless energy transfer from the tryptophans of membrane proteins to Py-3-Py. Lidocaine HCl increased the bulk lateral and rotational mobility of neuronal and model membrane lipid bilayes, and had a greater fluidizing effect on the inner monolayer than the outer monolayer. Lidocaine HCl increased annular lipid fluidity in SPMV lipid bilayers. It also caused membrane proteins to cluster. The most important finding of this study is that there is far greater increase in annular lipid fluidity than that in lateral and rotational mobilities by lidocaine HCl. Lidocaine HCl alters the stereo or dynamics of the proteins in the lipid bilayers by combining with lipids, especially with the annular lipids. In conclusion, the present data suggest that lidocaine, in addition to its direct interaction with proteins, concurrently interacts with membrane lipids, fluidizing the membrane, and thus inducing conformational changes of proteins known to be intimately associated with membrane lipid.

Sea-urchins (Anthocidaris crassispina) are widely distributed in the East Sea of Korea. The aim of this study was to evaluate the hepatoprotective effects of sea-urchin roe on bromobenzene (BB)-induced liver damage in rats. The antioxidative and detoxifying properties of sea-urchin roe in BB-poisoned rat liver was examined by chemical analysis of serum aminotransferase (AST, ALT), glutathione S-transferase (GST), $\gamma$-glutamylcystein synthetase, glutathione reductase, epoxide hydrolase, amino-N-demethylase (AD), aniline hydrolase (AH) enzyme activity, as well as lipid peroxide and glutathione contents. Sea-urchin roe inhibited the increase of serum AST, ALT enzyme activity. Increasing lipid peroxide contents and AD and AH activities were significantly decreased in ethanol extract of sea-urchin roe. GST, $\gamma$-glutamylcystein synthetase, glutathione reductase and epoxide hydrolase enzyme activities increased in sea-urchin roe-fed group, compared with the BB-treated group. These results suggest that sea-urchin roe facilitates recovery from liver damage by enhancing antioxidative defense mechanisms and hepatic detoxication metabolism.

Meat becomes brown and rancid during storage in the refrigerator and display in the case. Color changes, metmyoglobin formation and lipid oxidation are the important problems in the transportation / distribution of meat and retail display. The freshness of meat is determined by the sense of vision and smell. Since conventional method determining lipid oxidation is time consuming and destructive (it needs to homogenize meat with reagents, filtrate, time for reaction and read optical density using spectroscopy), more rapid and nondestructive technical tools are desired. The objective of this work was to evaluate near-infrared spectroscopy as an analytical tool for determining meat color, metmyoglobin formation and lipid oxidation. in beef, pork and chicken. Semitendinosus and longissimus thoracis muscles from six beef steers, biceps femoris and longissimus thoracis muscles from twelve LWD crossbred pigs, and superficial pectoral muscles from twenty-four broilers were used. About a 5-cm diameter and 1-cm thick sample (20.0g) was cut from the muscle and placed on plastic foam, over-wrapped with PVC film, and displayed under flourescent lights at 4 degrees C. during 10 days for beef and pork or 4 days for chicken. The spectra was measured by NIR systems Model 5500 Spectrophotometer using fiber optic scan at range of 400 - 1100 nm. Data were recorded at 2 nm intervals and 10 scans / 10 sec were averaged for every sample. Data obtained were saved as log 1/Re, where Re is the reflectance energy, and then mathematically transformed to second derivatives to reduce effects of differences in particle size. $L^{*}$, $a^{*}$ and $b^{*}$, and metmyoglobin formation were determined by conventional spectrophotometer using the integrating sphere unit. 2-Thiobarbituric acid reactive substances (TBARS) were measured for lipid oxidation. A multiple linear regression was used to find the equation which would best fit the data. The number of wavelengths used in the equation was selected based on the fewer number compared to the increasing multiple correlation and Decreasing standard error. (omitted)

Fluorescence probes located in different membrane regions were used to evaluate the effects of chlorpromazine HCl on structural parameters (transbilayer lateral mobility, annular lipid fluidity, protein distribution, and lipid bilayer thickness) of synaptosomal plasma membrane vesicles (SPMVs) isolated from bovine cerebral cortex. The experimental procedure was based on the selective quenching of 1,3-di(1-pyrenyl)propane (Py-3-Py) by trinitrophenyl groups, radiationless energy transfer from the tryptophan of membrane proteins to Py-3-Py, and energy transfer from Py-3-Py monomers to 1-anilinonaphthalene-8-sulfonic acid (ANS). In this study, chlorpromazine HCl decreased the lateral mobility of Py-3-Py in a concentration dependent-manner, showed a greater ordering effect on the inner monolayer than on the outer monolayer, decreased annular lipid fluidity in a dose dependent-manner, and contracted the membrane lipid bilayer. Furthermore, the drug was found to have a clustering effect on membrane proteins.
