Objective: This study was eanied out to investigate the effects of Raphani Semen on immuno-response in the mouse model of allergic asthma. Methods: In this study, BALB/C mice were divided into 6 groups: Normal (Non-treated group), Control (Group with not treated after allergic sensitization and induction by ovalbumin), Treat I (Group with the oral administration of saline after allergic sensitization and induction by ovalbumin), Treat n (Allergic asthma group treated with acupuncture (BL 13)), Treat III (Allergic asthma group treated with the oral administration of Raphani Semen) and Treat lV (Allergic asthma group treated with the herbal-acupuncture of Raphani Semen (BL 13)). The effect on cytokine was assessed by measuring cytokine (lL-2, IL-4, IL-5, IL-10, IL-12, IFN-r) in bronchoalveoar lavage fluid(ELISA). ResuJts : The results obtained as follows: 1. The production of Interleukin-2 was decreased significantly in Treat I group, Treat n group and Treat IV group as compared with Control group. 2. The production of Interleukin-4 was decreased significantly in Treat I group, Treat II group and Treat IV group as compared with Control group. Among them. the production of Interleukin-4 was decreased remarkably in Treat IV group as compared with other groups. 3. The production of Interleukin-5 was decreased significantly in Treat I group and Treat IV group as compared with Control group. 4. The production of Interleukin-10 was decreased significantly in Treat I group and Treat III group as compared with Control group. 5. The production of Interleukin-12 was all decreased significantly in Treat I group, Treat n group, Treat m group and Treat IV group as compared with Control group. 6. The production of Intelferon- showed no significant changes in Treat I group, Treat n group. Treat m group and Treat Ⅳ group as compared with Control group. Conclusion: These results show that the production of Interleukin-4, 5 was decreased significantly in aJlergic asthma group treated with the herbal-acupuncture of Raph Semen (BL 13), It is known that inactivity of Th2 cell constrained the revelation and controlled hypersenstive action. As to this mechanism, it is suggested that the herbal-acupuncture of Raphani Semen(BL 13) constrained the revelation of allergic asthma.

In this paper, we present evidence that the Korean red ginseng extract shows the immunomodulatory activities during postoperative chemotherapy after curative surgery in patients with advanced colon cancer. We measured the circulating interleukin-2 (IL-2), interleukin-8 (IL-8)and interleukin-10 (IL-10) as a immune modulator to evaluate the effect of Korean red ginseng. The mean preoperative value of IL-2 was similar in the non-RG group and the RG group (5.72 pg/ml versus 6.87 pg/ml, p>0.05). The mean value of IL-2 was compared with IL-2 from healthy control group, there was no significant difference (14.89 pg/ml versus 14.22 pg/ml, p>0.05). The mean preoperative value of IL-8 was higher in the non-RG group comparing with the RG group (30.92 pg/ml versus 36.25 pg/ml, p < 0.05). At postoperative 3 month, the mean values of IL-8 from non-RG and RG group down to 24.56 pg/ml and 21.46 pg/ml respectively. The IL-8 of RG group at 3 month showed no difference with that of HC group(21.46 pg/ml versus 16.31 pg/ml, p>0.05). The preoperative mean value of IL-10 of non-RG, RG and HC group was 11.56 pg/ml, 10.8 pg/ml, and 3.68 pg/ml respectively. At postoperative 3 month, the mean values of IL-10 from non-RG and RG group down to 8.45 pg/ml and 5.04 pg/ml respectively. In spite of decreasing IL-10 levels of both cancer Patients group with time, there was still significant difference with that of HC group (non-RG versus HC group, p=0.00, RC versus HC group, p=0.04). The results of this study suggest that the red ginseng extract may have some immunomodulatory properties associated with IL-2, IL-8 and IL-10 activity in patients with advanced colorectal cancer during postoperative chemotherapy. We think to need the further studies and a larger sample size to fully evaluate the antitumor effect of ginseng and need to establish this mechanism of action as well as identify the active components associated with antitumor activity and immunomodulation in patients with advanced colorectal cancer.

Objectives: Dendritic cell (DC)-based tumor immunotherapy needs an immunogenic tumor associated antigen (TAA) and an effective approach for its presentation to lymphocytes. In this study we explored whether transduction of DCs with lentiviruses (LVs) expressing the human interleukin-12 gene could stimulate antigen-specific cytotoxic T cells (CTLs) against human lung cancer cells in vitro. Methods: Peripheral blood monocyte-derived DCs were transduced with a lentiviral vector encoding human IL-12 gene (LV-12). The anticipated target of the human IL-12 gene was detected by RT-PCR. The concentration of IL-12 in the culture supernatant of DCs was measured by ELISA.Transduction efficiencies and CD83 phenotypes of DCs were assessed by flow cytometry. DCs were pulsed with tumor antigen of lung cancer cells (DC+Ag) and transduced with LV-12 (DC-LV-12+Ag). Stimulation of T lymphocyte proliferation by DCs and activation of cytotoxic T-lymphocytes (CTL) stimulated by LV-12 transduced DCs pulsed with tumor antigen against A549 lung cancer cells were assessed with methyl thiazolyltetrazolium (MTT). Results: A recombinant lentivirus expressing the IL-12 gene was successfully constructed. DC transduced with LV-12 produced higher levels of IL-12 and expressed higher levels of CD83 than non-transduced. The DC modified by interleukin -12 gene and pulsed with tumor antigen demonstrated good stimulation of lymphocyte proliferation, induction of antigen-specific cytotoxic T lymphocytes and antitumor effects. Conclusions: Dendritic cells transduced with a lentivirus-mediated interleukin-12 gene have an enhanced ability to kill lung cancer cells through promoting T lymphocyte proliferation and cytotoxicity.

Interleukin-32 (IL-32), a recently identified pro-inflammatory cytokine, is involved in the pathogenesis and progression of infections, cancer, chronic inflammation, and autoimmune disease. IL-32γ is the most active isoform in cell death and cell activation among nine distinct isoforms of IL-32. IL-32γ potentiates both osteogenic and osteoclastogenic capacities, and is critical in the coupling of bone resorption and bone formation for maintenance of bone homeostasis. IL-32γ is strongly associated with inflammatory bone disorders such as rheumatoid arthritis, ankylosing spondylitis, and osteoporosis. In this review, we summarize current research on the role of IL-32γ in inflammatory bone disorders, highlighting this cytokine as a novel target for prognostic marker and control of these diseases.

Interleukin-18 (IL-18) has been known to induce interferon-${\gamma}$ (IFN-${\gamma}$) production and promote Th1 immunity. Although mammalian IL-18 has been characterized in great detail, the properties and application of chicken IL-18 remain largely uninvestigated as of yet. In this study, we evaluated the immunomodulatory properties of Salmonella enterica serovar Typhimurium expressing chicken interleukin-18 (chIL-18) on immune responses induced by avian influenza (AI) and Newcastle disease (ND) vaccines. After oral administration of S. enterica serovar Typhimurium expressing chIL-18, chickens were vaccinated intramuscularly with the recommended dose of either inactivated AI H9N2 vaccine or ND (B1 strain) vaccine. Chickens receiving a primary vaccination were boosted using the same protocol 7 days later. Humoral and cell-mediated immune responses were evaluated in terms of HI antibody titers and proliferation and mRNA expression of IFN-${\gamma}$ and IL-4 of peripheral blood mononuclear cells (PBMC) in response to specific antigen stimulation. According to our results, oral administration of S. enterica serovar Typhimurium expressing chIL-18 induced enhanced humoral and Th1-biased cell-mediated immunity against AI and ND vaccines, compared to that of chickens received S. enterica serovar Typhimurium harboring empty vector. Therefore, we conclude that our proposed vaccination regimen using inactivated AI and ND viruses along with oral administration of S. enterica serovar Typhimurium expressing chIL-18 may provide a novel approach in protecting chicken from currently circulating AI and ND virus strains.

Objective: With the onset of stroke, white blood cells release several proinflammatory cytokines, including interleukin (IL)-6, IL-10, and tumor necrosis factor $(TNF)-{\alpha}$. It has been proven in previous studies that the release of these cytokines is related to the extent of damage to the brain and to overall prognosis. However, no studies have yet been performed to determine the connection with IL-6 and IL-10. Thus, this study is performed to see whether polymorphisms of IL-6, IL-10, and $TNF-{\alpha}$ genes that show increased serum concentration with the onset of stroke are related to stroke attack in Koreans. Methods : Peripheral blood samples derived from patients with stroke (n=100) and healthy controls (n=100) were taken under informed consent. In subjects with stroke, blood samples were obtained within 24 hours of stroke onset. Genomic DNA was isolated using the Wizard DNA Purification Kit (Promega, Madison, WI). Results : 1. Subjects with Heterozygote (GA) and Homozygote (AA) $TNF-{\alpha}$ gene types showed 2.433 and 20.457 times higher risks of being attacked by stroke, respectively, compared to subjects with wild type (GG) $TNF-{\alpha}$ gene type. The data was still statistically significant after adjusting for age, sex, history of smoking, and history of alcohol drinking. 2. Subjects with Homozygote (CC) IL-6 gene type showed 182.033 times higher risk of being attacked by stroke, compared to subjects with wild type (GG) IL-6 genes. This data was statistically insignificant (p=0.700). The data was still statistically insignificant after adjusting for age, sex, history of smoking, and history of alcohol drinking. 3. Subjects with Heterozygote (GA) and Homozygote (GG) IL-10 gene types showed 8.785 and 3.303 times higher risks of being attacked by stroke, respectively, compared to subjects with wild type (AA) IL-10 genes. The data was still statistically insignificant after adjusting for age, sex, history of smoking, and history of alcohol drinking. Conclusion : Our results suggest that the investigated $TNF-{\alpha}$ and IL-10 gene polymorphisms play an important role in stroke attack, but IL-6 gene polymorphism has not been found to associated with stroke.

Background: Cardiopulmonary bypass during open heart surgery causes systemic inflammatory respose. IL-10 is an anti-inflammatory cytokine that inhibits inflammatory process and protects organ function by down regulation of pro-inflammatory cytokine release and maintenance of blood level balance with pro-inflammatory cytokines. Mateial and Method: Plasma IL-10 levels were measured and analyzed in 22 patients who underwent open heart surgery (11 cases of coronary artery bypass graft, 11 cases of valve replacement) under cardiopulmonary bypass since 1988 January to July at Department of Thoracic and Czardiovascular surgery, Yeungnam University Hospital. 1g of methylprednisolone was administrated to thirteen patients randomly. Blood samp.es were taken and collected at the time of induction of anesthesia, 10 min before cardiopulmonary bypass, 10 min after starting of CPB, 10 min aftr aortic cross clamping, 10 min after ACC release, and 10 min, 2 hours, and `5 hours after CPB respectively. The plasma levels of IL-10 were determined by enzyme-linked immunosorbent assays(ELISA). Wilcoxon-Raule Sum test was used for statistical analysis. Result: In all 22 patients, cardiopulmonary bypass time was used for statistical analysis. Result: In all 22 patients, cardiopulmonary bypass time was 171$\pm$41.4 min and aortic cross clamp time was 118$\pm$36.5 min. Peak IL-10 level was achieved at 10 min after ACC(361.0$\pm$52.81pg/ml) and was decreased sharply at 2 hours after CPB. Peak IL-10 level was correlated positively with aortic cross clamp time(p=0.011); however, it did not correlated with bypass time(p=0.181). In valve replacement group, mean IL-10 level at peak point was 567.89$\pm$107.69 pg/ml and was significantly higher than that of coronary artery bypass group(205.67$\pm$192.70 pg/ml)(p<0.001). ACC time in valve replacement group was significantly longer than that of coronary artery bypass group(p<0.01), however, bypass time was not(p=0.212). Thirteen patients with steroid pretreatment before starting of CPB showed relatively higher plasma IL-10 level than in control group, however, no statistical significance was noted(p=0.19). Conclusion: plasma level of IL-10 was increased in association with cardiopulmonary bypass and revealed peak at 10 min after ACC release. IL-10 level was correlated positively with ACC time. Therefore, systemic inflammatory respeonse in association with cardiopulmonary bypass could be decreased by reducing ACC time during cardiac surgery.

Interleukin (IL)-15 is an essential immune-modulator with high potential for use in cancer treatment. Natural IL-15 has a low biological potency because of its short half-life and difficulties in mass-production. IL-15Rα, a member of the IL-15 receptor complex, is famous for its high affinity to IL-15 and its ability to lengthen the half-life of IL-15. We have double-transfected IL-15 and its truncated receptor IL-15Rα into CT26 colon cancer cells to target them for intracellular assembly. The secreted IL-15:IL-15Rα complexes were confirmed in ELISA and Co-IP experiments. IL-15:IL-15Rα secreting clones showed a higher anti-tumor effect than IL-15 secreting clones. Furthermore, we also evaluated the vaccine and therapeutic efficacy of the whole cancer-cell vaccine using mitomycin C (MMC)-treated IL-15:IL-15Rα secreting CT26 clones. Three sets of experiments were evaluated; (1) therapeutics, (2) vaccination, and (3) long-term protection. Wild-type CT26-bearing mice treated with a single dose of MMC-inactivated secreted IL-15:IL-15Rα clones prolonged survival compared to the control group. Survival of MMC-inactivated IL-15:IL-15Rα clone-vaccinated mice (without any further adjuvant) exceeded up to 100%. This protection effect even lasted for at least three months after the immunization. Secreted IL-15:IL-15Rα clones challenging trigger anti-tumor response via CD4⁺ T, CD8⁺ T, and natural killer (NK) cell-dependent cytotoxicity. Our result suggested that cell-based vaccine secreting IL-15:IL-15Rα, may offer the new tools for immunotherapy to treat cancer.

Objective : There are many reports that acupuncture has thermoregulatory effects on human and animals. To investigate the effect and mechanism of antipyretic action of acupuncture, we observed the body temperature and cytokine expressions in the hypothalamus of rats. Methods : Lipopolysaccharide (LPS, i.p., 2.5mg/kg) was injected to conscious rats (Sprague-Dawley, male, n=4l) to cause hyperthermia and simple needling (stainless steel, 0.25 mm o.d., 5 mm insertion for 10 sec with no manipulation) was performed bilaterally with the measurement of rectal temperature. Next, we sacrificed rats to remove brain and determined the level of mRNA for interleukin-6 (IL-6), $interleukin-1{\beta}{\;}(IL-1{\beta})$, interleukin-2 (IL-2) and $interferon-{\gamma}{\;}(IFN-{\gamma})$ in the hypothalamus by using reverse transcriptase-polymerase chain reaction (RT-PCR). Resul1s : Needling on forepaw (acupoint HT8) and needling on hindpaw (acupoint BL66 and acupoint LR2) significantly inhibited LPS-induced fever of rats (P<0.01, 10 min after treatment respectively), but same treatment on proximal tail (non-acupoint) did not cause any change on fever. The levels of IL-6 and $IL-1{\beta}$ mRNA in the hypothalamus was significantly enhanced by LPS-injection, while the level of IL-6 and $IL-1{\beta}$ mRNA was markedly reduced after treatment on BL66 (P<0.01). Treatment on forepaw reduced it slightly, but not significantly. Equivalent stimulation on proximal tail did not cause any changes. Conclusions : Our results indicate that acupuncture stimulation on various body parts has differential thermoregulatory effects on LPS-induced fever of rats with site-specificity. And, we suggest that its antipyretic action might be accompanied with the suppression of hypothalamic production of pro-inflammatory cytokine of immune system, IL-6 and $IL-1{\beta}$.

Objectives: Herbal acupuncture has been administered with Liriopis Tuber extract on the point of BL 13 (Pyesu) to treat bronchial asthma and a certain degree of clinical benefits have been observed but lacking scientific substantiation. Methods: The present report describes on Th1 cytokine (Interleukin-2, Interferon-gamma), Th2 cytokine, (Interleukin-4, Interleukin-5), and IL-12 in bronchoalveolar lavage fluid (ELISA). Five groups were devised to study the effects of herbal acupuncture with Liriopis Tuber extract at BL 13 (Pyesu) for airway inflammation in the mouse model with bronchial asthma. Results shows that herbal acupuncture with Liriopis Tuber extract at BL 13 increased Th1 cytokine (Interleukin-2) in allergic sensitization and allergic challenge, and decreased Th2 cytokine (Interleukin-2, Interleukin-5) in allergic sensitization.
