  • The purpose of this study was to investigate the potential hypoglycemic effect of adlay diets when total fiber consumption was controlled in streptozotocin-induced diabetic rats. Forty eight rats were fed for 3 weeks with either controlled in streptozotocin -induced diabetic rats. Forty eight rats were fed for 3 weeks with either control diets or experimental diets : raw mille adlay (RMA) raw whole adlay(RWA) , steamed milled adlay(SMA) or roasted mille adlay(OMA). The composition of the AIN-76 diet was modified to ensure the same composition of protein, carbohydrate , rat, and fiber between the control diet and experimental diets. The concentrations of glucose , insulin, glycogen, and protein in plasma, liver, or skeletal muscle were compared . Compared to diabetic control rats, plasma postprandial glucose levels tended to be decreased in RMA, RWA, SMA and OMA rats until the 2nd week, but no difference was shown at the 3 rd week. There was no significant difference in insulin levels among those groups. After glucose loading, the plasma glucose level of SMA was lower than that of diabetic control rats throughout 2 hrs. Liver glycogen was lower than control values in RMA and RWA rats and not different in SMA and OMA rats. The muscle protein level of RMA, RWA, SMA, and OMA rats tended to be lower than in diabetic control rats. There was no significant difference in muscle glycogen among groups. These results suggest that the hypoglycemic effect of an adlay diet is not significant when the amount of total fiber consumption is controlled.

  • The purpose of this study was to investigate the potential hypolipidemic effect of job's tears diet with the controlled intake of fiber in streptozotocin induced diabetic rats. Forty eight rats were fed either control diet or experimental diets (Raw, milled job's tears(RMJ); Raw, whole grain job's tears(RWJ);Steamed, milled job's tears(SMJ);Roasted, milled job's tears(OMJ)) for 3 weeks. The levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), free fatty acid(FFA) and triglyceride (TG) in plasma, liver and skeletal muscle were compared. Compared to diabetic control group, the level of plasma TC was lower in OMJ an SMJ fed rats, and was not different from that in RMJ and RWJ fed rats. The level of LDL-C was significantly lower in RMJ, OMJ and SMJ fed rats. For plasma HDL-C levels, no difference was observed among all group. Plasma FFA level significantly lower in RMJ, SMJ and RWJ fed rats, Plasma TG a levels of all job's ears fed groups were 50∼70% lower and liver TG levels of all job's tears fed groups were 70∼80% lower than those fo diabetic control group. For muscle TG, no differences were seen among all groups. These results suggest that steamed job's tears and roasted job's tears could have the potentaila on improving lipid profile fo diabetes in clinical setting and the different cooking methods of job's tears might affect the lipid profile of the diabetic rats.

  • This study was conducted to investigate the effects of Araliaceae water extracts on lipid concentrations in streptozotocin(STZ)-induced diabetic rats. The Male Wistar rats were divided into normal and diabetic group. The diabetic group was futher subdivided into the control group(DM) and the Araliaceae water extracts supplemented group: Aralia elata(AE), Acanthopanacis cortex(AC) and Ulmus davidiana(UD). The extracts were supplemented with 1.14% of raw Araliaceae/kg diet for 7 weeks. Diabetes was induced by injecting STZ(55 mg/kg B.W., i.p.) once 2 weeks before sacrifying. The net weight gain and feed efficiency ratio were significantly lower in the STZ-induced diabetic group than in the normal group. However, all of the Araliaceae water extracts supplemented groups resulted in an increase of body weight compared to the DM group. The triglyceride, total cholesterol and free cholesterol concentrations in plasma and liver were significantly higher in the DM group than in the normal group. However, the supplementation of Araliaceae water extracts increased plasma HDL cholesterol concentration, while decreased plasma VLDL, LDL-cholesterol concentra-tions in Araliaceae water extracts supplemented group.

  • Purpose: This study was performed to evaluate anti-thrombotic and anti-inflammatory effects of NeungaSoJeokTang water extract (NSJT). Methods: In the study of anti-inflammatory effects, NSJT was investigated using cultured cells and murine models. As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were determined in mouse lung fibroblast cells(mLFC) and RAW 264.7 cells. Results: Prior to the experiment, we evaluated sGOT, sGPT, BUN and creatine after the treatment. As a result, NSJT was innoxious on liver and kidney. In experiment of anti-thrombotic effect, NSJT inhibited the platelet aggregation induced by ADP and epinephrine, and inhibited pulmonary embolism induced by collagen and epinephrine. NSJT did not affect significantly the blood flow rate both in vitro and in vivo. NSJT increased platelet number and fibrinogen amount, and NSJT shortened PT and APTT in thrombus model induced by dextran. In experiment of anti-inflammatory effect, NSJT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression in a concentration-dependent manner in RAW 264.7 cell line, and inhibited significantly NO production at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent manner. NSJT inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of acute inflammation-induced Balb/c mice, and decreased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in spleen tissue, but increased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in liver tissue. NSJT increased survival rate at the 3th day in ICR mice with lethal endotoxemia induced by LPS. Conclusion: These results suggest that NSJT can be used for treating diverse female diseases caused by thrombosis and inflammation such as pelvic pain, pelvic inflammatory disease as well as vulvar pain due to vulvitis, vulvar vestibulitis and so on.

  • Objectives : Inflammation is important event in the development of vascular diseases including hypertension, atherosclerosis, and restenosis. Injinho-tang(IJHT) has been used as a traditional Korean herbal medicine since ancient times, and today it is widely used as a medication for jaundice associated with inflammation of the liver. The aim of this study was to determine whether IJHT and its components inhibit production of nitrite, an index of NO, and proinflammatory cytokines in lipopolysaccharide (LPS)-treated RAW 264.7 macrophages. Methods : Cytotoxic activity of IJHT and its components on RAW 264.7 cells was using 5-(3-caroboxymeth-oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. The nitric oxide (NO) production was measured by Griess reagent system. And proinflammatory cytokines were measured by ELISA kit. The levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression were detected by western blot. Results : IJHT and its components significantly inhibited the LPS-induced NO production and iNOS expression accompanied by an attenuation of tumor necrosis factor-alpha (TNF-${\alpha}$), interleukin-6 (1L-6), IL-$1{\beta}$ and monocyte chemoattractant protein-1 (MCP-1) formation in macrophages. Conclusions : IJHT and its components inhibit LPS-induced inflammation via decreasing cytokines production. These results indicate that IJHT and its components have potential as an anti-inflammation and anti-artherosclerosis agent.

  • In traditional oriental medicine, Gentianae Radix has been used clinically for clearing away 'heat', removing dampness and purging fire in the liver and gall bladder. However, there has been a lack of studies regarding the effects of Gentianae Radix on the immunological activities. The present study was conducted to evaluate the effect of Gentianae Radix on the regulatory effects of cytokines and nitric oxide(NO) for the immunological activities in Raw 264.7 cells. After the treatment of Gentianae Radix MeOH extract, cell viability was measured by MTT assay, and NO production was monitored by measuring the nitrite content in culture medium. The expression of COX-2 and iNOS was determined by immunoblot analysis, and the content of levels of cytokines in media was analyzed by ELISA kit. Results provided evidence that Gentianae Radix inhibited the production of nitrite and nitrate (NO), inducible nitric oxide synthase (iNOS), $interleukin-l{\beta}$ $(IL-l{\beta})$ and IL-6, and the activation of phospholylation of inhibitor ${\kappa}B{\alpha}$ ($p-I {\kappa}B{\alpha}$) in Raw 264.7 cells activated with lipopolysaccharide (LPS). These findings suggest that Gentianae Radix can make anti-inflammatory effect, which may playa role in adjunctive therapy.

  • Suaeda asparagoides (Miq.) is a salt marsh plant, long been prescribed in traditional medicine for the treatment of hypertension and liver toxification in Asian countries. The powder of S. asparagoides was added at the ratio of 0, 5, and 10%, respectively, of grain-type Meju to manufacture Doenjang in brine according to the salt concentration (8 and 12%). After 24 weeks of fermentation, the Doenjang samples were determined to have an anti-inflammatory effect on RAW 264.7 cells. Evaluation of the anti-inflammatory effect of Doenjang added S. asparagoides powder extracted using 80% EtOH, was performed to study the inhibition of pro-inflammatory factors such as NF-κB (nuclar factor κB), NO (nitric oxide), TNF-α (tumor necrosis factor alpha), IL-6 (interleukin-6), iNOS (inducible nitric oxide synthase), and COX-2 (cyclooxygenase-2) in lipopolysaccharide (LPS)-induced RAW 264.7 cells. The results showed that the Doenjang extracts reduced the production of NO, IL-6, COX-2, and iNOS increased in the LPS-stimulated RAW cell without cytotoxicity. In the case of the NF-κB and TNF-α there was no significant difference between the control and samples. In conclusion, these results suggest that Doenjang added with the S. asparagoides powder acts as functional fermented food with anti-inflammation effect.

  • Prunellae Spica is the spike or whole plant of Prunella vulgaris Linne, which has been used for clearing heat from the liver, brightening the eyes and treating headache in traditional oriental medicines. This study was conducted to evaluate the inhibitory effects of the aqueous extract of Prunellae Spica (PSE; PS extract) on the production of NO and PGE2 in LPS-activated Raw 264.7 cells. Cell viability was determined by MTT assay, and all three doses of PS extract (0.03, 0.1 and 0.3 mg/ml) had no significant cytotoxicity during the entire experimental period. The cells were treated with 1 ${\mu}g/ml$ of LPS 1 h before adding PS extract, and increased NO and PGE2 production were detected in LPS-activated cells compared to control. However, these increases were dose-dependently attenuated by treatment with PS extract. The inhibition of NO by PS extract was due to the suppression of iNOS expression via inhibition of $NF{\kappa}B$ nuclear translocation and proteolytic degradation of $I{\kappa}B{\alpha}$. The decreased level of PGE2 was derived from inhibition of COX-2 activity, but expression of COX-2 protein was not affected by PS extract. Moreover, PS extract reduced the elevated production of IL-${\beta}$ and IL-6 by LPS. These results demonstrate that PS extract has inhibitory effects on the production of NO and PGE2 as a consequence of the reduction of proinflammatory cytokines, especially IL-${\beta}$ and IL-6 in LPS-activated Raw 264.7 cells.

  • A total of 301 samples of bovine liver, spleen and omasum were collected from butchers and restaurants in Gwangju, Korea during 2012 and all samples were subjected to bacteriological examination and antibiotic residues. Also, this study was performed to survey the consciousness for hygiene of livestock workers who are handling bovine by-products in Gwangju. The detection rate of aerobic plate count (APC) was higher in summer than in other seasons in all by-products (P=0.000). The detection rate of E. coli count was lower in the liver than the spleen and omasum (P=0.000). Twenty four of the samples (8.0%) were contaminated with S. aureus while one spleen sample (0.3%) was contaminated with L. monocytogenes and finally 10 (3.3%) of the liver and omasum samples were contaminated with Cl. perfringens. Five of the twenty-four S. aureus isolates harbored enterotoxin gene. However, the cpe gene of Cl. perfingens was not detected among any of the 10 isolates. Antibiotic residues were not detected in the liver samples. The consciousness survey's results showed that most of them (58.8%) were safe.

  • The Lophius litulon liver was used as raw material for the extraction of fish oil via various extraction methods. The extraction rate by water extraction, potassium hydroxide (KOH) hydrolysis and protease hydrolysis were compared and the results revealed the protease hydrolysis extraction had a higher extraction rate with good protein-lipid separation as observed by optical microscope. Furthermore, subsequent experiments determined neutrase to be the best hydrolytic enzyme in terms of extraction rate and cost. The extraction conditions of neutrase hydrolysis were optimized by single-factor experiment and response surface analysis, and the optimal extraction rate was 58.40 ± 0.25% with the following conditions: enzyme concentration 2,000 IU/g, extraction time 1.0 h, liquid-solid ratio 1.95:1, extraction temperature 40.5℃ and pH 6.5. The fatty acids composition in fish oil from optimized extraction condition was composed of 19.75% saturated fatty acids and 80.25% unsaturated fatty acids. The content of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were 8.06% and 1.19%, respectively, with the ratio (6.77:1) surpassed to the recommendation in current researches (5:1). The results in this study suggest protease treatment is an efficient method for high-quality fish oil extraction from Lophius litulon liver with a satisfactory ratio of DHA and EPA.
