Colorectal cancer (CRC) is a worldwide health problem, being the third most commonly detected cancer in males and the second in females. Rising CRC incidence trends are mainly regarded as a part of the rapid 'Westernization' of life-style and are associated with calorically excessive high-fat/low-fibre diet, consumption of refined products, lack of physical activity, and obesity. Most recent epidemiological and clinical investigations have consistently evidenced a significant relationship between obesity-driven inflammation in particular steps of colorectal cancer development, including initiation, promotion, progression, and metastasis. Inflammation in obesity occurs by several mechanisms. Roles of imbalanced metabolism (MetS), distinct immune cells, cytokines, and other immune mediators have been suggested in the inflammatory processes. Critical mechanisms are accounted to proinflammatory cytokines (e.g. IL-1, IL-6, IL-8) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$). These molecules are secreted by macrophages and are considered as major agents in the transition between acute and chronic inflammation and inflammation-related CRC. The second factor promoting the CRC development in obese individuals is altered adipokine concentrations (leptin and adiponectin). The role of leptin and adiponectin in cancer cell proliferation, invasion, and metastasis is attributable to the activation of several signal transduction pathways (JAK/STAT, mitogen-activated protein kinase (MAPK), phosphatidylinositol 3 kinase (PI3K), mTOR, and 5'AMPK signaling pathways) and multiple dysregulation (COX-2 downregulation, mRNA expression).

This study was performed to determined the antioxidant activities, anticancer and immuno-activities of anthocyanin fraction from Rubus coreanus Miquel fruits (Bokbunja). Anthocyanin fraction extracted from Bokbunja revealed the presence of three anthocyanin components, which were tentatively identified as cyanidin 3-O-sambubioside, cyanidin 3-O-xylosylrutinoside and cyanidin 3-O-rutinoside using RP-HPLC/DAD/MS. The anthocyanin fraction from Bokbunja always showed reducing power and high scavenging activities against DPPH, hydroxy radical (OH) and superoxide anion radical ($O_2{^-}$) similar to general synthetic antioxidant and polyphenol compounds from plant origin. Anthocyanin fraction from Bokbunja showed high inhibition on proliferation of LNCaP and A549 cells and did not inhibit the proliferation of other cancer cells. Immuno-activities of Anthocyanin fraction from Bokbunja were investigated, it showed high promotion of human B and T cells growth about 50% and secretion of IL-6 and TNF-${\alpha}$ by treatment after 6 days. Over all, the result of the study suggest that anthocyanin fraction from Bokbunja displays antioxidant activity comparable to that general synthetic antioxidant, also, anthocyanin fraction from Bokbunja are expected to be good candidate for development into source of anticaner and immuno-activator agent in food industry.

In the present study, the anti-cancer effects of ginseng fermented with Phellinus linteus (GFPL) extract were examined through in vitro and in vivo assays. GFPL was produced by co-cultivating ginseng and Phellinus linteus together. Ginsenoside Rg3, Rh1 and Rh2 are important mediators of anti-angiogenesis and their levels in GFPL were enriched 24, 19 and 16 times, respectively, more than that of ginseng itself through the fermentation. GFPL exhibited distinct anti-cancer effects, including growth inhibition of the human lung carcinoma cell line A549, and promotion of immune activation by stimulating nitric oxide (NO) production in Raw 264.7 cells. Further evidence supporting anti-cancer effects of GFPL was its significant prolongment of the survival of B16F10 cancer cell-implanted mice. These results suggest that the GFPL may be a candidate for cancer prevention and treatment through immune activation and anti-angiogenic effects by enriching Rg3, Rh1 and Rh2.

We investigated the effect of pycnogenol (PYC) supplementation on retarding the immune dysfunction of CS7BL/6 mice after murine AIDS (MAIDS) development. Dysfunction of T and B cell mitogenesis from primary cultured splenocytes has been observed with retrovirus infection and PYC supplementation partially recovered the dysfunction of T and B cells. There was an abnormal shift of cytokine pattern with retrovirns infection, which was designated by the decreased secretion of Th1 cytokines and increased secretion of Th2 cytokines. PYC supplementation increased IL-2 and $IFN-\gamma$ secretion and decreased IL-4, IL-6, and $TNF-\alpha$ secretion, but it was not sufficient enough to maintain the normal level of these cytokines. Hepatic vitamin E level was significantly decreased by retrovirns infection, in accordance with increased hepatic lipid peroxidation level, whereas PYC supplementation normalized the hepatic level of vitamin E and lipid peroxidation. This study suggests that PYC supplementation may partially help retard the incidence of symptoms during MAIDS.

Most of the axons in the vertebrate nervous system are surrounded by a lipid-rich membrane called myelin, which promotes rapid conduction of nerve impulses and protects the axon from being damaged. Multiple sclerosis (MS) is a chronic demyelinating disease of the CNS characterized by infiltration of immune cells and progressive damage to myelin and axons. One potential way to treat MS is to enhance the endogenous remyelination process, but at present there are no available treatments to promote remyelination in patients with demyelinating diseases. Sulfasalazine is an anti-inflammatory and immune-modulating drug that is used in rheumatology and inflammatory bowel disease. Its anti-inflammatory and immunomodulatory properties prompted us to test the ability of sulfasalazine to promote remyelination. In this study, we found that sulfasalazine promotes remyelination in the CNS of a transgenic zebrafish model of NTR/MTZ-induced demyelination. We also found that sulfasalazine treatment reduced the number of macrophages/microglia in the CNS of demyelinated zebrafish larvae, suggesting that the acceleration of remyelination is mediated by the immunomodulatory function of sulfasalazine. Our data suggest that temporal modulation of the immune response by sulfasalazine can be used to overcome MS by enhancing myelin repair and remyelination in the CNS.

A 2${\times}$3 factorial arrangement of treatments was used to determine the effects of olaquindox and cyadox on immune response of Landrace${\times}$Large-White geld piglets that had been orally given 10$^{10}$ CFU of Escherichia coli (E. coli, O$_{139}$:K$_{88}$). Factors included (1) E. coli inoculation or control, and (2) no antimicrobials, 100 mg/kg olaquindox and 100 mg/kg cyadox in the basal diet respectively. E. coli inoculums were orally administered 7 days after the diets were supplemented with olaquindox and cyadox. The effects of the two antimicrobials were assessed in terms of: (1) average daily gain (ADG), (2) systemic immune response (the number of white blood cells and lymphocytes, leukocyte bactericidal capacity, lymphocyte proliferation response to PHA, immunoglobulin concentrations, and total serous hemolytic complement activity), and (3) intestinal mucosal immunity including the number of intraepithelial lymphocytes (IELs) and immunoglobulin A secreting cells (ASCs) in the intestinal lamina propria. E. coli inoculation reduced ADG (p<0.05) during the period of d 0 to d 14 after the challenge while the antimicrobial supplementations improved ADG (p<0.01) during the experiment. ADG in cyadox-supplemented pigs was higher (p<0.05) than that in olaquindox-supplemented pigs. The antimicrobials decreased IEL and ASC counts in the jejunum and ileum (p<0.01) while E. coli inoculation caused them to increase (p<0.01). Jejunal ASCs in the cyadox-supplemented pigs were lower (p<0.05) than those in the olaquindox-supplemented. E. coli elicited increase (p<0.05) in white blood cell counts, leukocyte bactericidal capacity, lymphocyte proliferation rate, serous IgA concentrations, and serous hemolytic complement activity. The antimicrobials decreased the measured systemic immune parameters, but not significantly (p>0.05). The data suggest that olaquindox and cyadox suppress E. coli-induced immune activation, especially intestinal mucosal immune activation, which may be involved in the observed growth promotion.

Background: Radix et Rhizoma Ginseng (thereafter called ginseng) has been used as a medicinal herb for thousands of years to maintain people's physical vitality and is also a non-organ-specific cancer preventive and therapeutic traditional medicine in several epidemiologic and preclinical studies. Owing to few toxic side effects and strong enhancement on body immunity, ginseng has admirable application potential and value in cancer chemoprevention. The study aims at investigating the chemopreventive effects of ginseng on cutaneous carcinoma and the underlying mechanisms. Methods: The mouse skin cancer model was induced by 7,12-dimethylbenz[a]anthracene/12-O-tetradecanoylphorbol-13-acetate. Ultraperformance liquid chromatography/mass spectrometry was used for identifying various ginsenosides, the main active ingredients of ginseng. Comprehensive approaches (including network pharmacology, bioinformatics, and experimental verification) were used to explore the potential targets of ginseng. Results: Ginseng treatment inhibited cutaneous carcinoma in terms of initiation and promotion. The content of Rb1, Rb2, Rc, and Rd ginsenosides was the highest in both mouse blood and skin tissues. Ginseng and its active components well maintained the redox homeostasis and modulated the immune response in the model. Specifically, ginseng treatment inhibited the initiation of skin cancer by enhancing T-cell-mediated immune response through upregulating HSP27 expression and inhibited the promotion of skin cancer by maintaining cellular redox homeostasis through promoting nuclear translocation of Nrf2. Conclusion: According to the study results, ginseng can be potentially used for cutaneous carcinoma as a chemopreventive agent by enhancing cell-mediated immunity and maintaining redox homeostasis with multiple components, targets, and links.

Content analysis of food advertisements was undertaken to investigate the nature of the messages related to health, nutrition or consumer-promotion in 2001 women's magazines. Advertisements on baby foods were collected from three women's magazines and the final samples obtained were 42 different copies of advertisements. All the messages in each sample were counted and calculated for their frequency (％). Messages were categorized into four areas (health, nutrition, non-nutrition, consumer promotion), and each area was classified into more detailed categories. Results showed that all the messages in 42 samples and average messages per advertisement were 1288 and 30.7, respectively. The most common type of promotional messages was health related (e.g., appeal to enhanced immune function and disease prevention and brain development), followed by consumer related, nutrition and non-nutrition messages in order. Messages about high quality and all natural ingredients were more emphasized in the consumer related category. Messages on fats (DHA, lecithin and arachidonic acid), proteins (neucleotides, taurine) and mineral (calcium, iron) were most frequently found in nutrition category. Amongst the three kinds of baby foods, formula ads had the most numerous messages related to health and nutrition. There were more consumer related messages in the ads of weaning foods, and more promotional messages about no addition of antiseptic, artificial additives, and food colors in the ads for older infant foods. Messages violating regulation (e.g., exaggerated or inaccurate or non-scientific messages) were frequently found in the advertisements of three kinds of baby foods. In conclusion, tighter supervision of food advertisements and nutrition education is required to protect the consumers from misleading advertisements.

Immunogenicity of dendritic cell-derived exosomes stimulated with Toxoplasma gondii lysates (TLA exo), mixed with cholera toxin as an adjuvant, was investigated in mice immunized via 2 mucosal routes (ocular vs intranasal). BALB/c mice were injected 3 times with TLA exo vaccine at 2 week interval, and the levels of IgG in serum and IgA in tear, saliva, feces, and vaginal wash were measured. To observe the expression of T. gondii-specific B1 gene, mice infected with ME49 T. gondii cysts were immunized with TLA exo or PBS exo (not stimulated with TLA), and their brain tissues were examined. The mice vaccinated via intranasal route elicited significantly higher humoral and mucosal immune responses compared with mice treated with PBS alone. Also, mice immunized via ocular route (by eyedrop) induced significantly higher T. gondii-specific IgG in serum and IgA in tear and feces in comparison with PBS controls. B1 gene expression was significantly lower in TLA exo vaccinated mice than in PBS or PBS exo vaccinated mice. These results demonstrated that ocular immunization of mice with TLA exo vaccine has the potential to stimulate systemic or local antibody responses. This study also highlighted an advantage of an eyedrop vaccine as an alternative for T. gondii intranasal vaccines.
