  • The nutritional status of host has a profound effect on immune response and its ability to defend aganinst invading pathogen. Almost all nutrient dificiencies impaired host defence, and more than recommended levels of certain nutrient enhance immune response beyond that observed with 'adequate'. But high-fat diets have been associated with various types of immune dysfunction in experimental animal models and humans. Also, high linoleic acid suppressed immune function and growth and metastasis of tumor than saturated fatty acids. The present review focused on the effect of dietary lipid on immune fuction, cytokine production and clinical conditions like infection, autoimmune disease and cancer.

  • Adjuvant is an immune enhancer commonly used during vaccination to enhance the host immune response. In the present study, we produced the several recombinant protein from immune related gene of olive flounder (Paralichthys olivaceus). Especially, to produce the soluble type of recombinant protein, we constructed the MBP (Maltose binding protein) fusion G-CSF (Granulocyte colony stimulating factor) recombinant protein among the flounder immune related genes. To verify the immune stimulatory effect and safety of this recombinant protein (rPoGCSF), expression changes of several immune genes were tested using quantitative real-time PCR method with gene specific primer from flounder head kidney leukocytes. As a result, we confirmed that the rPoGCSF has an ability of immune stimulatory effect, also it has broad range of pH and temperature.

  • The present study examined the ex vivo effect of Job's tear on immune function. Seven to eight week old mice(Balb/c) were fed a chow diet ad libitum two different concentrations (50 and 500 mg/kg BW) of water extract of Job's tear were orally administ every other day for two weeks. The results indicated that macrophage activation had occurred in the mice receiving 50 mg/kg B. W. of Job's tear water extract. Overall, using a mouse model, this study demonstrated that Job's tear extract may enhance immune function by regulating the $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ and IL-10 cytokine production capacity of activated macrophages in mice. This study may suggest that supplementation of Job's tear water extracts may enhance the immune function by regulating the enhancing the cytokine production by activated macrophage ex vivo.

  • Objective : The immune enhance is the main focus of current society that to increase resistance to invasion by pathogenic species of bacteria in body, stimulate the immune system and possibly protect against cancer or inflammatory disease. The present study aimed to evaluate the effect of Gentianae Radix extract on immune regulation in a LPS-induced mice model of acute inflammation. Methods : Gentianae Radix extract was administered orally at doses of 200 mg/kg/day or 400 mg/kg/day for 2 weeks before a intraperitoneally injection of LPS (1 mg/kg of 0.9% saline). After LPS-intraperitoneal injection 3 hours, blood was collected by cardiac puncture under ether anaesthesia from all animals, for the immune regulate efficacy verification based on blood or serum biomarkers (i.e., immune cells, cytokine, $PGE_2$, ROS, and $LTB_4$) analysis. Results : Compared to the control mice, the Gentianae Radix extract treatments significantly increased the count of immune cells (i.e., wite blood cell, neutrophils, and monocyte), and significantly reduced the lymphocyte. In addition, the Gentianae Radix extract treatments significantly decreased the pro-inflammatory cytokine (i.e., $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$), and significantly increased IL-10 of anti-inflammatory cytokine. Furthermore, the Gentianae Radix extracts treatments significantly increased the levels of $PGE_2$ and significantly decreased the levels of ROS, and $LTB_4$. Conclusions : The results indicate that Gentianae Radix extract alleviated acute inflammatory reaction though regulation of immune meditor. Thus, Gentianae Radix extract may raw material of development a health food and medicine option for the immune enhance.

  • Codium fragile is an edible seaweed in Asian countries that has been used as a thrombolytic, anticoagulant, antioxidant, anti-inflammatory, and immune-stimulatory agent. Ginseng has also been known to maintain immune homeostasis and to regulate the immune system via enhancing resistance to diseases and microorganisms. In this study, anionic macromolecules extracted from C. fragile (CFAM) were orally administered with red ginseng extract (100 mg/kg body weight) to cyclophosphamide-induced immunosuppressed male BALB/c mice to investigate the immune-enhancing cooperative effect of Codium fragile and red ginseng. Our results showed that supplementing CFAM with red ginseng extract significantly increased spleen index, T- and B-cell proliferation, NK cell activity, and splenic lymphocyte immune-associated gene expression compared to those with red ginseng alone, even though a high concentration of CFAM with red ginseng decreased immune biomarkers. These results suggest that CFAM can be used as a co-stimulant to enhance health and immunity in immunosuppressed conditions.

  • In order to investigate the effect of Row ginseng (Ra. G.; from $K{\acute{u}}msan$ province, Korea), White ginseng (W.G.; from $K{\acute{u}}msan$ province, Korea), and Red ginseng (Re. G.; form $K{\acute{u}}msan$ province, Korea) on immune response, the author used ICR mice having a body weight of about 20g as experimental animals dividing them into four groups-Saline, Ra. G, W.G., Re. G group. Delayed type hypersensitivity(DTH) and rosette forming cells(RFC) for cell-mediated immune response, hemagglutinin(HA) titers, hemolysin (HL) titers for humoral immune response were measured at 24 hours after challenge, The results were summarized as follows: 1) DTH was increased in all of the treated group as compared with the Saline group, with statistical significance(W.G.> Re. G. > Ra. G.). 2) RFC was increased in all of the treated group as compared with the Saline group, with statistical significance(W.G. > Re. G. > Ra. G.). 3) HA titer was increased in all of the treated group as compared with the Saline group, with statistical significance (Re. G.> W. G.> Ra. G.). 4) HL titer was increased in all of the treated group as compared with the Saline group, with statistical significance (Re. G. > W. G.> Ra. G.). Through the experimental study in ICR mice, these findings suggest that Raw ginseng, White ginseng and Red ginseng enhance both cell-mediated and humoral immune response with statistical significance.

  • There is the urgent need of new human health care's technology against cancers or tumors based on plasma electronics, medicine and biology. Main target of our study is to enhance efficacy and selectivity of plasma on cancer cells with metabolic modifiers and by inducing immune-modulations. We have evaluated the combination effect of plasma with metabolic modifiers (2-DG) on various solid and liquid cancers. Our findings suggest that 2-DG enhances the efficacy and selectivity of plasma and induces apoptosis in blood cancer cells through glucose deprivation. Finally, we conclude that 2-DG with non-thermal plasma may be used as a combination treatment against cancer cells. Our work also comprises plasma induced activation of immune cells; which find applications for curing various kinds of resistant tumors and other dreadful diseases. Plasma significantly activates immune cells which increases cell death in solid tumors in co-culture conditions.

  • Background: As an attempt to develop a strategy to improve the protective immune response to GM-CSF-secreting CT26 (GM-CSF/CT26) tumor vaccine, we have investigated whether the apoptogenic treatment of GM-CSF/CT26 prior to vaccination enhances the induction of anti-tumor immune response in mouse model. Methods: A carcinogeninduced mouse colorectal tumor, CT26 was transfected with GM-CSF gene using a retroviral vector to generate GM-CSF-secreting CT26 (CT26/GM-CSF). The CT26/GM-CSF was treated with ${\gamma}$-irradiation or mitomycin C to induce apoptosis and vaccinated into BALB/c mice. After 7 days, the mice were injected with a lethal dose of challenge live CT26 cells to examine the protective effect of tumor vaccination in vivo. Results: Although both apoptotic and necrotic CT26/GM-CSF vaccines were able to enhance anti-tumor immune response, apoptotic CT26/GM-CSF induced by pretreatment with ${\gamma}$-irradiation (50,000 rads) was the most potent in generating the anti-tumor immunity, and thus 100% of mice vaccinated with the apoptotic cells remained tumor free for more than 60 days after tumor challenge. Conclusion: Apoptogenic pretreatment of GM-CSF-secreting CT26 tumor vaccine by ${\gamma}$-irradiation (50,000 rads) resulted in a significant enhancement in inducing the protective anti-tumor immunity. A rapid induction of apoptosis of CT26/GM-CSF tumor vaccine at the vaccine site might be critical for the enhancement in anti-tumor immune response to tumor vaccine.

  • The effect of dietary vitamin E supplementation on immune responses was studied in breeder chickens during the maturing period. In experiment 1, 17-week old female birds were fed corn-soybean meal based diets supplemented with either 0, 40, 80, 120, or 160 mg vitamin E (all-rac-${\alpha}$-tocopherol acetate)/kg diet for 19 weeks. In experiment 2, 23-week old male birds were fed the corn-soybean meal based diet supplemented with either 0, 20, 40, 80 or 160 mg vitamin E/kg diet for 8 weeks. The chickens were evaluated for growth performance, antibody titer to sheep red blood cell (SRBC), Newcastle disease virus (NDV), infectious bursal disease virus (IBDV) and infectious bronchitis virus (IBV), and skin response to phytohemagglutinin-P (PHA-P). The results showed that supplemental vitamin E improved body weigh gain of laying pullets during peak-laying period but had no significant effect on growth performance of cockerels. For cockerels, addition of 20 mg vitamin E/kg diet significantly enhanced (p<0.05) immune response to SRBC compared to those added with 0, 80 and 160 mg vitamin E/kg diet; addition of 20 mg vitamin E/kg diet had higher (p<0.01) antibody titer to IBDV than those added with 40-160 mg vitamin E/kg diet. No significant effects on immune response were observed in laying pullets fed supplemental vitamin E. The findings suggest that moderate supplementation of vitamin E may enhance immune responses to selective antigens in cockerels but excessive vitamin E may depress specific immune response.

  • Objective : To broaden understanding about acupuncture and moxibustion therapy on AIDS and to promote base studies and clinical trials Materials and Methods : Analysis was given to more than 30 literatures including acupuncture and moxibustion therapy on AIDS-related sites explored by internet search engine named NAVER from Nov., 2000 to Feb. 20th, 2001 Results : 1. Acupuncture and moxibustion played great role as a complementary therapy in enabling AIDS patients to keep their antiretroviral therapy by enhancing immune system, ameliorating AIDS-related symptoms and side effect of antiretroviral drug 2. Acupuncture and moxibustion therapy had a broad spectrum indication from systemic or local signs of AIDS patients to signs of antiretroviral drug-related side effect 3. Contraindication of acupuncture and moxibustion therapy against AIDS patients include abstraction and moxibustion on the skin lesion, because of their easy exposure to inflammation 4. AIDS patients were regarded as the state of KI-HE(氣虛), EUM-HE(陰虛), YEOL-DOK(熱毒) in general 5. BO-KI(補氣), BO-HYUL(補血), BO-EUM(補陰), CHEONG-YEOL-HAE-DOK(淸熱解毒) were shown as a principle of acupuncture and moxibustion therapy for AIDS patients 6. Principle of selecting acupoints for AIDS patients had characteristics of enhancing immune system, detoxicating detrimental agents and relieving each AIDS related symptom appropriately 7. Acupuncture on 合谷(HAPKOK, LI4), 內關(NAE-GWAN, P6), 足三里(CHOK-SAMNI, S36) were applied to the early stage of AIDS in order to enhance immune system. Acupuncture on 血海(HYOLHAE, SP10), 三陰交(SAMUMGYO, SP6), (KOHWANG, B43) were applied to the intermediate stage of AIDS so as to enhance immune system and eliminate YEOL-DOK(熱毒) in blood. Moxibustion on 湧泉(YONGCHON, K1), 足三里(CHOK-SAMNI, S36) were applied to the late stage owing to enhance immune system more. Conclusion : The efficacy of acupuncture and moxibustion therapy on AIDS has been acknowledged to the world, moreover, it is proved to be significant as a complementary therapy on AIDS patients. Thus, more control group studies of the efficacy of acupuncture and moxibustion therapy on AIDS and clinical trials are considered to be necessary.
