  • In this study, the inflammation of ethanol extracts from Caryopteris incana (CI) and fermented C. incana (FCI) on induced to lipopolysaccharide with Raw 264.7 cell was tested. The composition profile of L. plantarum was changed by fermentation, and confirmed by HPLC analysis. We performed the 3-[4,5-dimethylthiazol]-2-yl]-2,5-diphenyltetrazolium bromide assay to evaluate the toxicity of CI and FCI extracts. In cell viability, cell toxicity was not shown at 5, 10 and $15{\mu}g/mL$ of CI extracts and 10, 20, 30 and $40{\mu}g/mL$ of FCI extracts. The results of inducible nitric oxide synthase and cyclooxygenase-2 protein production were confirmed to be inhibitory in a concentration-dependent manner, respectively. Additionally, protein expression of nitric oxide and prostaglandin $E_2$ by CI and FCI extracts were also inhibited in a concentration-dependent manner. In the result of pro-inflammatory cytokine, $15{\mu}g/mL$ concentration of CI extracts was showed tumar necrosis factor $(TNF)-{\alpha}$ (57.3%), interleukin (IL)-6 (35.2%), and $IL-1{\beta}$ (48.0%), respectively. And $40{\mu}g/mL$ of FCI extracts was showed $TNF-{\alpha}$ (34.6%), IL-6 (32.1%), and $IL-1{\beta}$ (30.0%), respectively. These results suggest that FCI extracts showed better effect of anti-inflammatory than CI extracts. Therefore, it was found that both CI and FCI can be used as an excellent material for the development of new anti-inflammatory resource.

  • Atopic dermatitis (AD) is characterized by chronic relapsing inflammation and is associated with hyper-production of immunoglobulin E (IgE). Recent studies have suggested that one of the treatments to alleviate symptoms of AD could be a supplementation of probiotics, Lactobacillus, Rhamnosus, Bifidus, etc. The purpose of this study was to evaluate the effects of probiotics on immune parameters in NC/Nga mice treated with 1-chloro-2,4-dinitro-benzene (DNCB). To induce atopic dermatitis, DNCB was treated to the back of mice for 2 weeks. Then, NC/Nga mice were divided into the four experimental groups randomly. Probiotics fragment, probiotics with other complex (Lactobacillus rhamnosus GG, Bifidobacterium lactis Bb-12LbL, L. plantarum K8, L. plantarum K8 fragment, ${\gamma}$-linolenic acid), antihistamine, and distilled water were administrated orally to the NC/Nga mouse for 4 weeks of experimental period. The groups were probiotics fragment group (DPF), probiotics with other complex group (DPOC), antihistamine group (DAH) and distilled water group (DDW) as a control group. The levels of serum IgE, interlukin-4 (IL-4), interlukin-5 (IL-5), interferon-gamma (IFN-${\gamma}$) and spleenocyte IgE were measured. The levels of serum IgE were significantly different among the four experimental groups. Before the treatment, there was no differences among the groups. However, from the first through the third week of the treatments, the levels of serum IgE in the probiotics (DPF, DPOC) and antihistamine (DAH) groups were lower than those of control group (p < 0.05). The levels of serum IL-4 of DPOC group was significantly lower than that of control group (p < 0.05) and serum IL-5 levels of DPF, DPOC, and DAH groups were significantly lower than that of control group. The levels of serum IFN-${\gamma}$ were not different among the four experimental groups. The levels of serum IgE in supernatant of spleen lymphocytes were not significantly different among the groups. These results suggest that probiotics supplementation showed partial effectiveness in the DNCB treated NC/Nga mice via modulation of IgE level and IL-4, IL-5 production. Based on these findings, probiotics exhibited the inhibitory effect via IL-4 production thereby inhibited the production of IgE in atopic animal model NC/Nga mice.

  • Crinum asiaticum Linne var. japonicum has long been used as a rheumatic remedy, an anti-pyretic, an anti-ulcer treatment, and for the alleviation of local pain and fever in Korea and Malaysia. In order to investigate the possibility of Crinum asiaticum Linne var. japonicum extract as a cosmetic ingredient, we measured its anti-inflammatory effect by inhibition of iNOS (inducible nitric oxide synthase), and the release of PGE2, IL-6, and IL-8. HPLC experiment after extraction with 95% ethanol at pH 3.5 showed that Crinum asiaticum Linne var. japonicum was mainly composed of lycorine (up to 1%), a well-known immunosuppressant. The content of lycorine varied depending on the type of tissue analyzed and the extraction method. In anti-inflammatory assay for inhibition of nitric oxide formation on lipopolysaccharide (LPS)- activated mouse macrophage RAW 264.7 cells, the ethanolic extract of Crinum asiaticum showed inhibitory activity of NO production in dose-dependent manner ($IC_{50} = 83.5 {\mu}g/mL$). Additional study by RT-PCR demonstrated that the extract of Crinum asiaticum significantly suppressed the expression of the iNOS gene. Moreover, the extract of Crinum asiaticum did not show my cytotoxicity, but did show cell proliferation effect against LPS ($10{\sim}60%$ increase of tell viability). In an assay to determine inhibition of the $H_2O_2$-activated release of PGE2, IL-6, and IL-8 in human normal fibroblast cell lines, the release of PGE2 and IL-6 was almost completely inhibited above concentrations of 0.05% and 1%, respectively. Moreover, the release of IL-8 was completely inhibited over the entire range of concentrations (> 0.0025%). The result showed that the extract of Crinum asiaticum Linne var. japonicum has sufficient anti-inflammatory effect. There-fore, Crinum asiaticum Linne var. japonicum extract may be useful as an ingredient of cosmetic products.

  • Plants as well as crops are damaged by a combination of the hot and dry winds that has been a major factor in the reduction of crop production. A means to protect them from damaging conditions is to consider a coating material. In this study, we established laboratory screening methods to find a coating material to protect a crop from rapid transpiration caused by various factors. In a test measuring the weight loss of kidney bean seedlings for 6 days, Avion treatments decreased its weight loss (P=0.05). Owing to long-time spend in completing this assay, we performed a more simple method using a cobalt chloride paper strip, which changes from blue to red colors under water condition. Beewax, guagum, paraffin liquid, soybean oil, and PE-635 gave a waterproofing effect above 37 and 43% at 0.5 and 1 h after treatment, respectively. However, these tested materials did not show significant waterproofing results at 2 h. Although the methods produced reasonable results, a screening method to obtain more objective data is needed. An alternative is to use an instrument that can detect the transpiration of crop leaves. In a preliminary test using barley leaves, a portable photosynthesis system showed transpiration inhibition of 2% soybean oil and 10 times-diluted Avion under field conditions. In another test using the leaves of maize seedlings and apricot tree, 2% liquid paraffin and plant oils such as apricot oil, linseed oil, olive oil, and soybean oil showed significant transpiration inhibition (P=0.05). Especially, paraffin liquid and soybean oil selected from above tests gave good transpiration inhibitory effects against rice at 2%. In addition, the mixture of 2% soybean oil and a spreader showed more elevated inhibition results comparing with soybean oil or the spreader alone indicating that the spreader may be attributed to more uniform diffusion of the hydrophobic material onto the leaf surface of maize seedlings. The hydrophobic material coated physically the stomata and cuticle layers on leaf surfaces of rice. These hydrophobic materials screened in this study are expected to be used as plant coating materials.

  • We studied the antioxidant, the anti-inflammatory, antithrombotic, and antiobesity activities of seven different kinds of edible plants. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ABTS radical scavenging activities were determined as a measurement of antioxidant activity. NO production inhibition by the macrophage cell line (Raw 264.7) treated with lipopolysaccharide (LPS) was carried out to assess anti-inflammatory activity. Thrombin inhibitory activity was measured for its antithrombotic function and inhibition of 3T3-L1 cell differentiation was evaluated as a measurement of antiobesity activity. Total phenolic components and total flavonoid contents were measured to determine functional materials in medicinal plants. Common sage, Japanese lady bell, and hairy agrimony showed high antioxidant activity ($IC_{50}$) of less than $100{\mu}g/mL$. All samples used in this study showed anti-inflammatory activity. Common sage, hairy agrimony, and hooker chives showed antithrombotic effects. Hairy agrimony showed the highest antithrombotic effect (98.1%). Common sage, Japanese lady belly, hairy agrimony, and hooker chives showed reduced 3T3-L1 cell differentiation and hooker chives strongly inhibited lipid accumulation in the cells compared to other medicinal plants. Common sage and hairy agrimony contained more than 1 mg GAE/g of phenolic compounds and more than 1 mg CE/g of flavonoids. Functional activities were different by plant part and extraction method from each sample. These results suggest that common sage, Japanese lady belly, hairy agrimony, and hooker chives may be used as healthy food sources with antioxidant, anti-inflammatory, antithrombotic, and antiobesity activities, and appropriate extracting methods from each plant need to be developed.

  • This study was carried out to investigate the effects of tributyrin (TB) on the growth performance, pro-inflammatory cytokines, intestinal morphology, energy status, disaccharidase activity, and antioxidative capacity of broilers challenged with lipopolysaccharide (LPS). A total of 160 one-day-old Cobb broilers were allocated to 1 of 4 treatments, with 4 replicated pens per treatment and 10 birds per pen. The experiment consisted of a $2{\times}2$ factorial arrangements of treatments with TB supplementation (0 or 500 mg/kg) and LPS challenge (0 or $500{\mu}g/kg$ body weight [BW]). On days 22, 24, and 26 of the trial, broilers received an intraperitoneal administration of $500{\mu}g/kg$ BW LPS or saline. Dietary TB showed no effect on growth performance. However, LPS challenge decreased the average daily gain of broilers from day 22 to day 26 of the trial. Dietary TB supplementation inhibited the increase of interleukin-$1{\beta}$ (in the jejunum and ileum), interleukin-6 (in the duodenum and jejunum), and prostaglandin $E_2$ (in the duodenum) of LPS-challenged broilers. Similar inhibitory effects of TB in the activities of total nitric oxide synthase (in the ileum) and inducible nitric oxide synthase (in the jejunum) were also observed in birds challenged with LPS. Additionally, TB supplementation mitigated the decrease of ileal adenosine triphosphate, adenosine diphosphate and total adenine nucleotide and the reduction of jejunal catalase activity induced by LPS. Taken together, these results suggest that the TB supplementation was able to reduce the release of pro-inflammatory cytokines and improve the energy status and anti-oxidative capacity in the small intestine of LPS-challenged broilers.

  • Objective: This study was conducted to determine catalytic properties of wheat phytase with exopolyphosphatase activity toward medium-chain and long-chain inorganic polyphosphate (polyP) substrates for comparative purpose. Methods: Exopolyphosphatase assay of wheat phytase toward polyP75 (medium-chain polyP with average 75 phosphate residues) and polyP1150 (long-chain polyP with average 1150 phosphate residues) was performed at pH 5.2 and pH 7.5. Its activity toward these substrates was investigated in the presence of Mg2+, Ni2+, Co2+, Mn2+, or ethylenediaminetetraacetic acid (EDTA). Michaelis constant (Km) and maximum reaction velocity (Vmax) were determined from Lineweaver-Burk plot with polyP75 or polyP1150. Monophosphate esterase activity toward p-nitrophenyl phosphate (pNPP) was assayed in the presence of polyP75 or polyP1150. Results: Wheat phytase dephosphorylated polyP75 and polyP1150 at pH 7.5 more effectively than that at pH 5.2. Its exopolyphosphatase activity toward polyP75 at pH 5.2 was 1.4-fold higher than that toward polyP1150 whereas its activity toward polyP75 at pH 7.5 was 1.4-fold lower than that toward polyP1150. Regarding enzyme kinetics, Km for polyP75 was 1.4-fold lower than that for polyP1150 while Vmax for polyP1150 was 2-fold higher than that for polyP75. The presence of Mg2+, Ni2+, Co2+, Mn2+, or EDTA (1 or 5 mM) exhibited no inhibitory effect on its activity toward polyP75. Its activity toward polyP1150 was inhibited by 1 mM of Ni2+ or Co2+ and 5 mM of Ni2+, Co2+, or Mg2+. Ni2+ inhibited its activity toward polyP1150 the most strongly among tested additives. Both polyP75 and polyP1150 inhibited the monophosphate esterase activity of wheat phytase toward pNPP in a dose-dependent manner. Conclusion: Wheat phytase with an unexpected exopolyphosphatase activity has potential as a therapeutic tool and a next-generational feed additive for controlling long-chain polyP-induced inappropriate inflammation from Campylobacter jejuni and Salmonella typhimurium infection in public health and animal husbandry.

  • Objectives : The objective of present study is to evaluate anti-arthritic effects of dried pomegranate concentrate powders (PCP), Eucommiae Cortex aqueous (EC) and ethanolic (ECe) extracts, Achyranthis Radix aqueous (AR) and ethanolic (ARe) extracts on the primary cultured rat articular chondrocytes. Methods : MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium Bromide) assay was performed cytotoxic effect of test substances. In addition, anti-inflammatory effects were also observed on the lipopolysaccaride (LPS) treated chondrocytes through prostaglandin $E_2\;(PGE_2)$ production and 5-lipoxygenase (LPO) activities, and inhibitory effects on metalloproteinase (MMP)-2 and MMP-9 activities were observed on the recombinant human interleukin $(rhIL)-1{\alpha}$ treated chondrocytes with their extracellular matrix (ECM) related mRNA expressions - collagen type II, SOX9 and aggrecan. Results : As results, ECe and ARe showed obvious cytotoxicity against primary cultured rat articular chondrocytes at a dose level of 10 mg/ml, respectively. However, no obvious cytotoxic effects of PCP, EC and AR were demonstrated at a dose level of 10 mg/ml, on the primary cultured rat articular chondrocytes. In addition, treatment of LPS $50{\mu}g/ml$ induced significant increases of $PGE_2$ contents and 5-LPO activities indicating inflammatory responses of the primary cultured rat articular chondrocytes, and also decreases of cell viabilities, increases of MMP-2 and MMP-9 activities with decreases of extracellular matrix (ECM) related collagen type II, SOX9 and aggrecan mRNA expressions were observed by treatment of $rhIL-1{\alpha}$ 50 ng/ml, suggesting damages on the primary cultured rat articular chondrocytes and related ECM degradations. However, these inflammatory responses and related ECM degradations were inhibited by pretreatment of all test substances, in order of PCP > ECe > ARe > EC > AR, and $rhIL-1{\alpha}$ induced chondrocytes deaths are inhibited by treatment in order of PCP > EC > AR > ECe > ARe. Conclusions : Taken together, it is expected that mixed formulation of PCP as main components with appropriate proportion of EC and AR as additional components will be achieved a potent alternative medicinal food for osteoarthritis.

Effects of Some Metabolic Inhibitors on Phototactic Movement in Cyanobacterium Synechosystis sp. PCC 6803 PTX (람세균 Synechocystis sp. PCC 6803 PTX의 주광성 운동에 미치는 몇가지 대사 억제제의 효과)

  • For understanding physiological nature of phototaxis in Synechocystis sp. PCC 6803 PTX(S. 6803 PTX), we examined the effects of some metabolic inhibitors and cation ionophore on the phototactic movement. In the presence of DCMU, which blocks the photosynthetic electron transport just after photosystem II acceptor, there was no inhibitory effect on the phototaxis up to $100\;\mu\textrm{M}$. Instead, the respiratory electron chain inhibitor such as sodium azide dramatically impaired the phototaxis in S. 6803 PTX. These observations indicate that the phototaxis is linked not to photo-phosphorylation, but to respiratory phosphorylation. When the cells were treated with un couplers such as CCCP or DNP, which dissipate the electrochemical gradient of proton($\Delta\mu_{H}+$) across the cytoplasmic membrane, these chemicals did not affect phototaxis. In contrast, when cells were treated with DCCD or NBD which deprive cells of A TP but leave $\Delta\mu_{H}+$ intact across the membrane, the phototactic movement was severly reduced. These results imply that ATP production, not proton motive force, is involved in the phototactic movement in this organism as a driving motive force. The application of specific calcium ionophore A23187 strongly impaired positive phototaxis. Calcium fluxes should be engaged in the sensory trans-duction of phototactic orientation. Finally, when ethionine was supplimented to culture media, the photomovement of this organism was inhibited. This implies that methylation/demethylation mechanism controls the process of phototaxis in S. 6803 PTX like chemotaxis in E. coli and Salmonella typhimurium.murium.
