This study investigated the perception, consumer pattern and satisfaction of the ginseng products of 600 people in the Seoul area surveyed from Feb. 1 to 28, 2011. The perception and satisfaction tests were performed using a 5-point scale (1=disagree (dissatisfy) very much, 5=agree (satisfy) very much. People perceived ginseng to have refreshment (3.86), immuno-modulation (3.78), anticancer (3.51), and antiaging (3.41) properties. People in their 20s (4.02) scored high on refreshment compared to people in their 60s and over (3.73). Most people (79.8%) consume ginseng products and prefer red ginseng (74.3%). More people in their 40s (54.1%) and 50s (48.2%) consume ginseng products for refreshment than people in their 20s (38.7%), 30s (41.5%) or 60s and over (40.0%). However, more people in their 50s (36.1%) and 60s and over (43.6%) consume ginseng products for disease prevention than people in their 20s (8.6%). Most people (66.4%) take ginseng all year round. People in their 20s (2.70) showed a smaller satisfaction score of the taste of ginseng products than those in their 30s (3.21), 40s (3.23), 50s (3.26) and 60s and over (3.38).
Purpose: Cigarette smoking is a major risk factor in periodontal diseases. The pathogenesis of periodontal diseases may be affected by alterations of the inflammatory response by smoke. Nitric oxide (NO) is a gaseous, colorless, highly reactive, short-lived free radical with a pivotal role in the regulation of various physiological and pathological mechanisms in the body. It is important in host defense and homeostasis, on the one hand, whereas, on the other hand, it modulates the inflammatory response in periodontitis, leading to harmful effects. The aim of this study was to assess the levels of NO in both the serum and saliva of smokers and nonsmokers having chronic periodontitis and to compare them with periodontally healthy controls. Methods: Sixty subjects participated in the study and were divided into three groups: group I, healthy nonsmoking subjects; group II, nonsmoking patients with chronic periodontitis; group III, smoking patients with chronic periodontitis. Each group consisted of twenty subjects. The biochemical estimation of NO in the collected serum and in the saliva was performed using the Griess colorimetric reaction. Results: The results showed that the mean value of the salivary and serum NO was greater in group II than in group I, and also greater in group III than in group II. Conclusions: NO appears to play an important and rather complex role in the immuno-inflammatory process and in the remodeling and maintenance of osseous structures. It is therefore logical that modulation of this mediator has potential for the treatment of a number of inflammatory conditions including periodontal disease.
The obtained results are summarized as follows 1. New findings are reporting year by year as for the study related to Anti-inflammatory mechanism of Bee Venom therapy. 2. The Anti-inflammatory effect of Bee Venom therapy is achieved through counterirritation, stimulations to adrenal cortex, immuno-regulation, antioxidation, removal of free radicals, modulation of AGP gene induction. 3. The chief components of Bee Venom related to Anti-inflammatory effect are Melittin, MCD peptide, Apamin, Adolapin etc. 4. Melittin binds to secretory phospholipase A2 and inhibits its enzymatic activity. 5. Melittin blocks neutophil O2-production. 6. MCD peptide(Peptide 401) stimulates the mast cell secrets histamine, Anti-inflammatory effect caused by this is 'conterirritation'. 7. Melittin & Apamin have an anti-inflammatory effect by inducing cortisone secretion. 8. MCD peptide & Apamin increase immunologic fuction by stimulating hypophysis & adrenal cortex and have an anti-inflammatory effect by inhibiting synthesis of prostaglandin from arachidonic acid. 9. Adolapin have an anti-inflammatory effect by inhibiting COX. 10. Bee Venom have an anti-inflammatory effect by suppressing AGP($\alpha$-acid glycoprotein). 11. Bee Venom have an anti-inflammatory effect by inhibiting NO, iNOS, PLA2, COX-2, TNF-$\alpha$, IL-1, NF-${\kappa}B$, MAP kinase.
Melittia inouei (Yuri Nabang) larvae are used as a crude drug in East Asia for treating stomach cancer and inflammation, and currently reared as a pharmaceutical insect in Jejudo, Korea. This study evaluated the immuno-modulating activity of these extracts, by determining the level of, cytokine production from mouse splenocytes stimulated with the extracts. The Melittia inouei larvae extracts did not induce the splenocyte proliferation. On the other hand, they stimulated the splenocytes to produce cytokines such as $TNF-{\alpha}$, whereas they did not stimulate IL10, IL12 or $IFN-{\gamma}$. The aqueous portion of its plant (Tri-chosanthis kirilowii) extract (sap) was found to be a potent inducer of NO production from the CPAE cells. However, it showed weak inhibitory effects on vascular endothelial growth factor (VEGF) production from splenocytes. These data suggests that a Melittia inouei larvae extract immune modulatory activity in cytokine prodcutions such as $TNF-{\alpha}$ and VEGF which might be related its anticancer effect.
BACKGROUND/OBJECTIVES: Spirulina, a blue-green alga, is widely produced and commercialized as a dietary supplement with bio- and immune-modulatory functions. We have previously shown that spirulina had favorable effects on lipid profiles, immune functions, and antioxidant capacity in healthy Korean elderly. Despite favorable effect of spirulina supplementation, some sub-populations have shown a poor response to supplementation. Obesity is a factor related to poor-response. Therefore, the purpose of this study was to determine the immuno-modulation, antioxidant capacity, and lipid-lowering effect of spirulina in obese and non-obese Korean elderly. SUBJECTS/METHODS: The subjects were 78 elderly aged 60-87 years. In a randomized double blind, placebo-controlled study, subjects were fed either placebo or spirulina daily, at 8 g for 12 weeks. Subjects were divided into the non-obese group and the obese group based on body mass index (BMI) criteria for Asians suggested by the International Obesity Task Force: $BMI<25kg/m^2$ (non-obese) and $BMI{\geq}25kg/m^2$ (obese). RESULTS: In the non-obese group, spirulina supplementation showed a significant lowering effect on plasma concentration of total cholesterol and LDL-cholesterol, a significant increase in interleukin (IL)-2 concentration (P < 0.01) and a significant increment (P < 0.05) in IL-2/IL-6 ratio, and a significant increase in total antioxidant status level and a significant decrease in thiobarbituric acid reactive substances level. However, these effects were not observed in the obese group. CONCLUSION: These results demonstrated that blood lipid lowering and immune and antioxidant improving response for spirulina supplement was affected by obesity in Korean elderly.
Despite of the importance of the primordial follicle (PMF) recruitment, factors and mechanisms for process are poorly understood. To evaluate expression and role of the follicular transition from PMF to PMF/primary follicles (PMIF) in the present study, we evaluated expression of lats1, lats2, cyclin A1, and cyclin A2 mRNA and protein, and elucidated and role of lats1-cyclin A in the follicular transition from PMF to PRIF. To analysis of differential expression in PMF and PMIF, each stage follicles were collected by day1 and day5 of immuno-compromised rats (ICR) and analyzed by real-time PCR for the genes. For localization of mRNAs and proteins of the genes, in situ hybridization and immunohistochemistry were performed. We confirmed that the lats1, lats2, cyclin A1, and cyclin A2 mRNA were more expressed in PMF than PMIF. Localization of the four genes expression were observed in nuclei of oocytes from the arrested primordial, and in the surrounding granulosa cells of the growing follicles. The mRNA expressions were gradually decreased with follicular development. From immunohistochemistry studies, Cyclin A1 protein expression were observed in oocyte cytoplasmas of early stage follicles, while observed in granulose cells and oocyte nucleoli during growing follicles. This study suggested that the presence of lats gene family might perform negatively regulation of cell proliferation by modulation of the CDC2/Cyclin A complex activity. lats-cyclin A genes in oocytes of the early stage follicles might play a role in the meiotic cell cycle arrest of the primary oocytes at the primordial follicle stage as well as the follicular growth.

Generative and vegetative parts of the cactuses have had a long-lasting position in folk medicine and their effects could partly be confirmed in scientific experiments. Nowadays, the cactus, fruits, and cladodes are the focus of many studies because of their desirable properties. Therefore, the summarized reports of valuable properties of medicinal plants may be a good way to familiarize researches with a new source of drugs with lower side effects and higher efficacy. Opuntia dillenii, a well-known member of the Cactaceae family, is used as a medicinal plant in various countries and grows in the desert, semi-desert, tropical and sub-tropical areas. It shows diverse pharmacological activities such as: antioxidant, anti-inflammatory, anti-tumor, neuroprotective, hepatoprotective, hypotensive etc. OD fruit also possesses valuable constitutes for instance: betalains, ascorbic acid, total phenol, protein as well as essential elements which suggest the significant potential of this plant as a complementary therapy against several pathological conditions. This review describes experimental evidence about pharmacological and therapeutic potential of OD in order to give the basis of its application in the prevention and treatment of some chronic diseases. More studies on OD can help better understanding of its pharmacological mechanism of action to explain its traditional uses and to identify its potential new therapeutic applications.
Mushroom-derived polysaccharides, which are the primary bioactive constituents, are beneficial for human health. Polysaccharides have immuno-modulation, antitumor, and antioxidant properties. Additionally, they have antiviral properties and protect against chronic radiation stress. In this study, high yield water-soluble polysaccharides were obtained from Pleurotus djamor var. roseus basidiocarps. The crude polysaccharide (CP) was extracted sequentially by hot water and ethanol precipitation. The yield of the brown CPs was 5.6% dw. Diethylaminoethyl cellulose and Sepharose-6B column chromatography of CPs generated several fractions. Total glucan content was determined in all the fractions. The F1 fraction displayed the highest sugar content and was considered as a purified polysaccharide (PP). The total glucan and β-glucan content in the four fractions ranged between 76.85-2.95% and 75.08-1.46%, respectively. The yield of the PPs was 300 mg, and it was obtained as a white powder. The PPs were characterized by Fourier-transform infrared spectroscopy (FTIR) and thin-layer chromatography. The FTIR spectral details confirmed the presence of a xylopentose polysaccharide. The antioxidant activity of the PPs was evaluated using in vitro 1,1-diphenyl-2-picryl-hydrazyl (DPPH) free radical scavenging assay and superoxide radical scavenging assay. The PPs showed strong DPPH free radical and superoxide anion radical scavenging activities in a dose-dependent manner. Purified PPs free of phenolics, protein, and carbohydrates were mainly responsible for the radical scavenging activity. The data suggest the potential of PPs as natural antioxidants.

Background : PS-341 is a novel, highly selective and potent proteasome inhibitor, which showed cytotoxicity against some tumor cells. Its anti-tumor activity has been suggested to be associated with modulation of the expression of apoptosis-associated proteins, such as p53, $p21^{WAF/CIP1}$, $p27^{KIP1}$, NF-${\kappa}B$, Bax and Bcl-2. c-Jun N-terminal kinase (JNK) and glycogen synthase kinase-$3{\beta}$ (GSK-$3{\beta}$) are important modulators of apoptosis. However, their role in PS-341-induced apoptosis is unclear. This study was undertaken to elucidate the role of JNK and GSK-$3{\beta}$ in the PS-341-induced apoptosis in lung cancer cells. Method : NCI-H157 and A549 cells were used in the experiments. The cell viability was assayed using the MTT assay and apoptosis was evaluated by proteolysis of PARP. The JNK activity was measured by an in vitro immuno complex kinase assay and by phosphorylation of endogenous c-Jun. The protein expression was evaluated by Western blot analysis. Dominant negative JNK1 (DN-JNK1) and GSK-$3{\beta}$ were overexpressed using plasmid and adenovirus vectors, respectively. Result : PS-341 reduced the cell viability via apoptosis, activated JNK and increased the c-Jun expression. Blocking of the JNK activation by overexpression of DN-JNK1, or pretreatment with SP600125, suppressed the apoptosis induced by PS-341. The activation of caspase 3 was mediated by JNK activation. Blocking of the caspase 3 activation suppressed PS-341-induced apoptosis. PS-341 activated the phosphatidylinositol 3-kinase (PI3K)/Akt pathway, but its blockade enhanced the PS-341-induced cell death via apoptosis. GSK-$3{\beta}$ was inactivated by PS-341 via the PI3K/Akt pathway. Overexpression of constitutively active GSK-$3{\beta}$ enhanced PS-341-induced apoptosis; in contrast, this was suppressed by dominant negative GSK-$3{\beta}$ (DN-GSK-$3{\beta}$). Inactivation of GSK-$3{\beta}$ by pretreatment with lithium chloride or the overexpression of DN-GSK-$3{\beta}$ suppressed both the JNK activation and c-Jun up-regulation induced by PS-341. Conclusion : The JNK/caspase pathway is involved in PS-341-induced apoptosis, which is negatively regulated by the PI3K/Akt-mediated inactivation of GSK-$3{\beta}$ in lung cancer cells.

Background: The expression of the adhesion molecules on the cell surface is important in the movement of cells and the modulation of immune response. DILD starts as an alveolitis and progresses to pulmonary fibrosis. So adhesion molecules in these patients is expected to be increased. There are several reports about adhesion molecules in DILD in terms of the percentage of positive cells in immuno-stain, in which the interpretation is subjective and the data were variable. Methods: So we measured the relative median fluorescence intensity(RMFI) which is the ratio of the FI emitted by bound primary monoclonal antibody to FI emitted by isotypic control antibody of the cells in BALF of 28 patients with DILD(IPF:10, collagen disease:7, sarcoidosis:9, hypersensitivity pneumonitis:2) and 9 healthy control. Results: RMFI of the ICAM-1 on AM($3.30{\pm}1.16$) and lymphocyte($5.39{\pm}.70$) of DILD were increased significantly than normal control($0.93{\pm}0.18$, $1.06{\pm}0.21$, respectively, p=0.001, P=0.003). RMFI of the CD18 on lymphocyte was also higher($24.9{\pm}14.9$) than normal($4.59{\pm}3.77$, p=0.0023). And there was a correlation between RMFI of ICAM on AM and the % of AM(r=-0.66, p=0.0001) and lymphocyte(r=0.447, p=0.0116) in BALF. Also RMFI of ICAM on lymphocyte had a significant (r=0.593, p=0.075) correlation with the % of IL-2R(+) lymphocyte in BALF. The soluble ICAM(sICAM) in serum was also significantly elevated in DILD($499.7{\pm}222.2\;ng/ml$) compred to normal($199.0{\pm}38.9$) (p=0.00097) and sICAM in BAL fluid was also significantly higher than normal control group($41.8{\pm}23.0\;ng/ml$ vs $20.1{\pm}13.6\;ng/ml$). There was a Significant correlation between sICAM level in serum and the expression of ICAM-l on AM(r=0.554, p=0.0259).Conclusion: These data suggest that in DILD the expression of adhesion molecules is increased in the AM and BAL lymphocytes with elevated serum sICAM, and these parameter may be useful in determining disease activity.
