  • Recently, various marine algae have been considered as a natural resource for anti-inflammation. In this research, we investigated the anti-inflammatory activity of Ulva pertusa Kjellman ethanol extract (UPKEE). This study showed that UPKEE inhibited the secretion of cytokines including IL-6, $TNF-{\alpha}$, and $IL-1{\beta}$, and reduced the expression of $NF-{\kappa}B$ and mitogen-activated protein kinases (MAPKs) as well as iNOS and COX-2. In the formation of mouse ear edema test, three doses (10, 50, 250 mg/kg body weight) of UPKEE showed inhibitory activity after inducing inflammation using croton oil. In conclusion, we found that UPKEE showed an inhibitory effect on $NF-{\kappa}B$ and MAPKs, and reduced the secretion of inflammatory cytokines. This result suggests that UPKEE can be used as a natural anti-inflammatory resource in food industry.

  • This study was conducted to compare probiotic activities and physiological functions of Bifidobacterium longum Mk-G7 with weveral commercial and type strains of bifidobacteria. bif. longum MK-G7 showed the highest acid tolerance against HCl and acetic acid, whereas bif. infantis Y-1 showed the lowest acid tolerance and more than 4 log cycles of viable cell count decreased due to acid injuty. Viable cell counts of bifidobacteria strains decreased more than 1.5 log cycles owing to oxygen toxicity, with the exception of Bif. longum MK-G7, Bif. infantis Y-2, Bif. longum Y-3, Bif. longum Y-6, and Bif. longum RD-13 showed the highest bile tolerance, whereas Bif. longum MK-G7 showed a medium level of bile tolerance. Only Bif. longum MK-G7 howed much higher antibiotic resistance against both tetracycline and penicillin-G in the MIC(minimum inhibitory concentration) level of 24.8 mg/I and 0.52mg/I, respectively. Bif longum Y-6, and Bif. bifidum ATCC 29539 showed more than 80% of anti-mutagenicity against NQO(4-nitroquinolinel-oxide). Since the production of cytokines such as $TNF(tumor necrosis factor)-{\alpha}$ and IL (interleukin)-6, and NO(nitric oxide) in the macrophage cell line Raw 264.7 cells increased as Bif. longum MK-G7 cell concentration increased, ti was suggested that Bif. longum MK-G7 is able to enhance immunopotentiating activity in vitro. When freeze-dred Bif. longum MK-G7 was administered to mice at the dose of 1,2,4, and 6 g/kg of body weight, all of the mice survived in all feeding groups, proving the GRAS(generally recognized as safe) status of Bif. longum MK-G7. When fermented milk containing Bif. longum MK-G7 was administered to human volunteers, viable cell count of total bifidobacteria and anaerobes in the feces increased up to 0.5 log cycles more than before the administration. In particular, Bif. logum MK-G7 ingibited the growth of Bacteroides at the level of 1.0-1.5 log cycles.

  • Objectives : The purpose of this study is to inquire into the effect of different concentrations of bee venom pharmacopuncture to inhibit genesis of pro-inflammatory cytokines and to inhibit nuclear factor (NF)-${\kappa}B$ activation on type II collagen induced arthritis. Methods : The experiment was divided into category of the normal group (NOR)-no treated group, control group (CON)-CIA (collagen induced arthritis) induced group, and 4,000 : 1 bee venom group (BV-L)- 4000:1 bee venom pharmacopuncture treated group after CIA, and 2000:1 bee venom group (BV-H)- 2,000 : 1 Bee venom pharmacopuncture treated group after CIA. RA was induced in the mice via injecting $50{\mu}{\ell}$ C II mixed CFA. The bee venom pharmacopuncture was applied on $ST_{35}$ for 19 days from the 3rd day of RA inducement. To research the effect on the expression of IKK ($I{\kappa}B$ kinase), iNOS (inducible nitric oxide synthase) & COX-2 (cyclooxygenase-2) mRNA, RT-PCR was performed on synovial membrane cells from the knee joint of CIA mice. Results : The PMA-induced $I{\kappa}B$ kinase (IKK), inducible nitric oxide synthase (iNOS) and cyclooxygenase -2 (COX-2) mRNA expression were dose-dependantly decreased in bee venom treated with synoviocytes. In mice treated with bee venom pharmacopuncture, foot thickness and the damage of synovial membranes of the joint was lessened, and the activation of RA-related pro-inflammatory cytokines such as MIF, TNF-${\alpha}$ and MMP-9 was significantly decreased. The activation of iNOS and COX-2 was suppressed by the inhibition of NF-${\kappa}B$. In addition, each data was shown that 2,000 : 1 bee venom pharmacopuncture was more effective than 4,000 : 1 bee venom pharmacopuncture. Conclusions : It is speculated that bee venom pharmacopuncture has the therapeutic effect of palliating the damage of the synovial membrane and inflammation on RA by suppressing of NF-${\kappa}B$ activation.

  • Objectives : The aim of present study was to evaluate the beneficial effect of Scutellariae Radix (SR) and Scutellariae Radix EtOH-heated at 200℃ (SR200) using lipopolysaccharide (LPS) treated intestine of mice.Methods : Extract of SR and SR200 were orally administrated. Their effects were compared with vehicletreated LPS and normal groups. Subsequently, we measured reactive oxygen species (ROS) and nitric oxide in the serum and western blotting in the intestine.Results : The average weight in LPS treated (Vehicle) group was lowered significantly compare to that in non-treated normal group and this weight loss in the vehicle group was effectively prevented by the administration of SR and SR200 respectively. The increased oxidative stress biomarker levels such as reactive oxygen species (ROS) and nitric oxide (NO) in the serum was markedly decreased by treated with SR200. The decreased levels of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) induced by LPS injection were significantly restored by both SR and SR200 treatment. Moreover, increased inflammatory mediators and cytokines such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) in the LPS treated vehicle mice were significantly decreased through down-regulation c-JUN through reduction of oxidative stress.Conclusions : SR and SR200 could have benefit effect through down-regulation of abnormal oxidative stress in LPS induced intestine injury mice. Moreover, The anti-inflammatory activity of SR200 extract was better than SR extract in the LPS induced intestine injury mice.

  • Objectives The purpose of this study was to investigate the effects of Cheunggihwadamhwan (CGHDH) extract on lowering lipid, antioxidation and production of proinflammatory cytokines in rats fed on high fat diet. Methods 40 Male Sprague-Dawley rats were fed on high fat diet for 8 weeks and 32 rats (above 400 g) were randomly divided into 4 groups (8 mice in each group) : control group, 100 mg/Kg CGHDH group, 200 mg/Kg CGHDH group, 300 mg/Kg CGHDH group. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1 time/1 day) for 4 weeks. And We fed each experimental group of rats basal diet and administered an extract of Cheunggihwadamhwan extracts (100 mg/kg, 200 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid in plasma and liver, concentration of proinflammatory cytokines, antioxidative activity and gene expression. The gene expression level was investigated by the way of reverse transcription-polymerase chain reaction (RT-PCR). Results 1. Concentration of plasma FFA, plasma TG, plasma total cholesterol and plasma LDL-cholesterol showed a significant decrement in Cheunggihwadamhwan groups. However, concentration of plasma HDL-cholesterol showed a significant increment in 200, 300 mg/kg Cheunggihwadamhwan groups. 2. Concentration of liver total cholesterol and liver TG showed a significant decrement in Cheunggihwadamhwan groups. 3. Concentration of plasma TBARS showed a significant decrement in all Cheunggihwadamhwan groups. Concentration of liver TBARS showed a significant decrement in 200, 300 mg/kg Cheunggihwadamhwan groups. Concentration of liver GSH-Px, SOD and CAT showed a tendency to decrease in all Cheunggihwadamhwan groups. 4. Concentration of plasma IL-$1{\beta}$, plasma IL-6, TNF-$\alpha$ and NO, showed a tendency to decrease in all Cheunggihwadamhwan groups. Concentration of plasma IL-10 showed a tendency to increase in all Cheunggihwadamhwan groups. 5. In the analysis of reverse transcription-polymerase chain reaction (RT-PCR), the gene expression of Apo-B and Apo-E in the Cheunggihwadamhwan groups showed a low expression than that of control group. The ratio of Apo-B expression per $\beta$-actin expression in the showed a significant decrement in all Cheunggihwadamhwan groups. The ratio of Apo-E expression per $\beta$-actin expression in the showed a significant decrement in 300 mg/kg Cheunggihwadamhwan groups. Conclusions According to this study, the extract of Cheunggihwadamhwan showed a positive effect of lowering lipid, antioxidation and a control of producing proinflammatory cytokines.

  • The incidence rate of stomach cancer in Bali, Indonesia, is estimated to be strikingly lower than that in Japan. We conducted an on-site ecological study to investigate the association between the stomach cancer incidence and Helicobacter pylori (H. pylori) infection. Recruiting 291 healthy persons (136 men and 155 women) from the general population in Bali, Indonesia, we conducted a urea breath test (UBT) to examine H. pylori infection, along with a pepsinogen test to detect chronic atrophic gastritis and urine analysis to estimate sodium and potassium excretion. UBT positivities were 9% (2-15, 95% confidence interval) for men and 7% (1-12) for women, and positive cases for H. pylori IgG antibodies were 1% (0-3) for men and 3% (0-5) for women, significantly lower than the respective values in Japan. Positive pepsinogen tests in Bali were 0% (0-0) for men and 1% (0-4) for women, also significantly lower than the Japanese figures. Computed values for daily salt excretion were $13.3{\pm}4.1g$ (mean${\pm}$SD) for men and $11.1{\pm}3.1g$ for women, as high as corresponding Japanese consumption values. Moreover, the estimated potassium excretion was $3.2{\pm}0.7g$ for men and $2.8{\pm}0.6g$ for women in Bali, significantly higher than the figures in Japan. There were no associations across genetic polymorphisms of IL-beta, TNF-alpha, and PTPN11 with UBT positivity. The low incidence of stomach cancer in Bali may thus mainly be due to the rare H. pylori infection. Namely, the bacterium infection seems to be a critical factor for gastric cancer rather than host or other environmental factors.

  • Purpose : To provide data on exercise prescription for obesity management and prevention of cardiovascular disease in girl's high school and to prepare basic data for more effective exercise program for lifestyle improvement and prevention of lifestyle-related diseases. This study examines the effects on brain nerve growth factor and inflammatory factors, and the relationship between obesity factor and brain neuron cell production factor and inflammatory factor changes by complex exercise. Methods : The subjects of the study were obese students with a body fat percentage of 30 % or higher after obtaining body fat percentage of high school girls in C-city. Among them, 20 students who wanted to participate in the program of this study and did not participate in special exercise and diet therapy within the last 6 months were radio-sampled into groups of exercise group and control group, but attendance rate was low and The final exercise group (9) and control group (9) were measured, except for one student who did not respond. Results : Analysis of the range of variation in body composition, BMI, lean body mass, and the interaction between the groups showed significant differences (p<.05). TC, TG, HDL-C, and LDL-C as variables of blood lipids, TC and TG were not significantly different and TG was significantly different (p<.05) in interactions. HDL-C showed a significant difference (p<.01) in interactions, an increase in exercise group, and a significant decrease in control group (p<.05). There was a significant difference (p<.05) in BDNF interaction, an increase in the exercise group and a decrease in the control group, but no significant difference. NGF tended to increase in both exercise and control groups. IL-6 had a significant difference in timing (p<.05) and significantly decreased (p<.01) in the exercise group, and TNF-α interacted with timing (p<.05), and a significant increase in the control group. Conclusion : This study confirmed 12-week compound exercise program was effective in increasing the expression of basal fitness or CNS factor, but not enough to actually improve brain function. Fat mass and obesity are also affecting vascular inflammatory factors.

  • The objective of this study was to evaluate the immunomodulatory activity of crude polysaccharide separated from Cudrania tricuspidata leaf. C. tricuspidata polysaccharide (CTP) was extracted by ethanol precipitation. Immunomodulation activity was tested in macrophage cells (RAW 264.7 and bone-marrow derived macrophage) and splenocytes. CTP treatment significantly increased cell proliferation up to $250{\mu}g/mL$ in both RAW 264.7 and bone-marrow derived macrophages. In this concentration range (below $250{\mu}g/mL$), nitric oxide and cytokine [tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-6] production also significantly increased. Similarly, splenocyte proliferation dosedependently increased except for the $1,000{\mu}g/mL$ treated group. Regarding cytokine production activity in splenocytes, CTP treatment significantly increased production of Th 1 type cytokines [interferon $(IFN)-{\gamma}$] production but not Th 2 type cytokines (IL-4). Therefore, the results indicate that CTP may have a potential effect on immunomodulatory activity in various immune cells, and this is useful for development of immune enhancing adjuvant materials as a natural ingredient.

  • This study was indicated to enhance the anti-inflammation activities by the fermentation of the fruits of Aronia melanocarpa (Michx.) Elliott. The extracts by 70% ethanol (EE) showed better biological activities than those by hot water (WE) from campared result of the effect of extraction solvents. Then, the extract from 70% ethanol extraction was further fermented by lactic acid, denoted as FEE. For antioxidant activities, the FEE had showed the highest value as 0.832 of reducing powder, in comparison with those of EE and WE. Cytotoxicity of the water extraction (WE) was measured for 12.06% in addition of $1.0mg/m{\ell}$ of FEE. For anti-inflammation activities, NO production from the macrophage, RAW 264.7 was observed as $7.24{\mu}M$ and $8.52{\mu}M$ from FEE and EE, respectively. Prostaglandin $E_2$ ($PGE_2$) production from human fibroblast cell, CCD-986sk, was also estimated for $152pg/m{\ell}$ in addition of $1.0mg/m{\ell}$ of the FEE. The lowest production of both IL-6 and TNF-${\alpha}$ were $3.5pg/m{\ell}$ and $865.5pg/m{\ell}$, respectively in addition of $1.0mg/m{\ell}$ of the FEE, whereas $74.5pg/m{\ell}$ and $982.4pg/m{\ell}$ in treated with same concenrations of the EE. It was also found that the FEE was higher amounts than other extracts through HPLC analysis of the anthocyanins. These results strongly indicate that fermentation process of the lactic acid could enhance anti-inflammation activities of extracts by increasing the amounts of the anthocyanins, especially cyanidin-galactoside. Our results suggest that the application of the fermentation process for other medicinal herbs can be improved their biological activities.
