청양생진(淸凉生津), 해갈지구(解渴止嘔)의 효능이 있으며, 한국등에서 항당뇨병성 한약으로서 사용되어 온 비파엽의 열수출물의 당뇨병치료효과를 검증하기 위하여 alloxan으로 유발된 당뇨병흰쥐의 혈장포도당농도 및 인슈린농도를 측정하였다. 비파엽처리군의 혈장 포도당농도는 현저히 증가하였으며 혈장인슈린농도는 크게 감소하지 않았다. 한편, 당뇨병유발의 내재적인 요소로 알려진 사이토카인인 $IL-1{\beta}$로 당뇨병을 유발한 뒤 그 효과를 검정했다. 즉, 실험동물을 interleukin-$1{\beta}$로 처리하여 실험적으로 당뇨병을 유발한 후 glucose의 린산화(燐酸化)에 관여하는 glucokinase와 hexokinase의 활성을 살펴보았다. 그 결과, 비파엽엑기스는 interleukin-$1{\beta}$과잉투여 당뇨병으로 인하여 증가된 혈액내glucose농도를 감소시키고 insulin과잉분비를 정상으로 회복시키는데 효과적이었다. 동시에 $IL-1{\beta}$에 의해 유도된 당뇨마우스에 대한 비파엽(批把葉)엑기스 투여(投與)가 췌장glucokinase와 hexokinase의 활성을 촉진하는 것으로 나타나 $IL-1{\beta}$유발 당뇨병에 효과가 있는 것으로 사료되었다.

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.

Objectives ; This study was to investigate the anti-cancer effects of herbal acupuncture with distilled fresh ginseng. The herbal acupuncture was injected to Chung-wan($C.V_{12}$) and Wisu($BL_{21}$) of mice that were subjected to Sarcoma-180 adbominal cancer cell and A549 human epithelial lung cancer cells in vitro. Methods : Anti-cancer effects of distilled fresh ginseng herbal acupuncture were tested by measruing Cox, Bcl-2, and Bax by using RT-PCR in A549 human epithelial lung cancer cells in vitro. And four weeks old Balb/c line male mice weighing around $20\;{\pm}\;3g$ were used to measure survival rate and anti-cancer effect to outputs of interleukin-2 and interleukin-4 using flow cytometry, possibility of mRNA menifestation using RT-PCR, and Cox mRNA. The results are as follows. Results : 1. In measuring mRNA menifestation in Cox, Bcl-2, and Bax by using RT-PCR in A549 human epithelial lung cancer cells in vitro, the result showed that fresh ginseng decreased Cox-2 which is directly involved in Inflammation process. 2. Survival rate was measured in an anti-cancer effect experiment against Sarcoma-180 abdorminal cancer. Median survival time of controlled group was 27 days, of experiment group I was 21 days, and of experiment group II was 27 days. Therefore, experiment group I showed -22.2% increase in survival rate and experiment group II showed no difference compare to controlled group. 3. There was no difference between condition group and controlled and experiment group in measuring outputs of interleukin-2 and interleukin 4 by using flow cytometry 4. In measuring outputs of interleukin-2 by using ELISA, there was no significant difference between condition group and controlled group and there was decrease in experiment group II compared to conditioned and controlled group. 5. In measuring cytokine mRNA menifestation by using RT-PCR, experiment group I showed increase of mRNA menifestation in interleukin-2,4 and $interferon-{\gamma}$ and experiment group II showed no significant difference in $interferon-{\gamma}$. Conclusion : According to the results, fresh ginseng herbal-acupuncture took a little effects in cancer. In using distilled fresh ginseng herbal acupuncture has effect on Cox-2 decrease. However, the difference in concentration of fresh ginseng showed no effect on killing cancer cell. It is assumed that inaccurate concentration of herbal acupuncture and fresh ginseng component could be the reason for this result. Therefore, future consideration will be studies on herbal acupuncture concentration.

This study investigated the effects of Oligonol intake on cortisol, interleukin (IL)-$1{\beta}$, and IL-6 concentrations in the serum at rest and after physical exercise loading. Nineteen healthy sedentary male volunteers participated in this study. The physical characteristics of the subjects were: a mean height of $174.2{\pm}2.7$ cm, a mean weight of $74.8{\pm}3.6$ kg and a mean age of $22.8{\pm}1.3$ years. Each subject received 0.5 L water with Oligonol (100 mg/day) (n = 10) or a placebo (n = 9) daily for four weeks. The body composition, the white blood cell (WBC) and differential counts as well as the serum cortisol, IL-$1{\beta}$, and IL-6 concentrations were measured before and after Oligonol intake. The cortisol concentration and serum levels of IL-$1{\beta}$ and IL-6 after Oligonol intake were significantly decreased compared to before treatment (P < 0.01, respectively). In addition, the rate of increase of these factors after exercise was decreased compared to the placebo group. There was no change in the WBC and differential cell counts. These results suggest that oral Oligonol intake for four weeks had a significant effect on inhibition of inflammatory markers in healthy young men.

Recombinant interleukin-2 (IL-2) has demonstrated as an antineoplastic agent in mice and human, but the relatively low response rates observed in clinical trials. Therefore, the present study was undertaken in order to evaluate therapeutic activities of IL-2 for the establishment of therapeutic applications. At the onset of the experiment, normal C3H/HeN mice were injected with $3{\times}10^6$ RD-995 tumor cells, murine ultraviolet radiation-induced fibrosarcoma, subcutaneously. Beginning on day 25, experimental groups were treated with a 5-day course of IL-2 (subcutaneous injection of 30,000 IU every 12 hours for 5 days). The result of this experiment revealed that RD-995 tumor grew progressively in control mice. Subcutaneous IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 treated mice were observed compared with the control mice.

목적 : 본 연구는 Interleukin 4 Receptor (IL-4R) 유전자 다형성이 중풍의 발병과 관련이 있는지 알아보기 위해 수행되었다. 대상: 대구한의대학교부속 한방병원에 입원한 중풍환자 56명과 종합건진센터에 내원한 중풍 기왕력이 없는 건강인 83명을 대상으로 하였다. 방법 : 각 그룹에서 개개인마다 DNA를 분리 정제한 후 Taq polymerase로 증폭하여 한천 겔에서 전기영동을 하여 PCR 산물을 확인하였다. PCR 산물은 Pyrosequencing 과정을 통하여 IL4R의 유전형이 자동으로 판정되었다. 결과 : A/A, A/G, G/G의 세가지 유전자형이 검출되었으며 중풍군과 대조군 사이에 유의성 있는 차이가 발견되었다(p=0.005). 그러나 개별 allele 빈도에 있어서는 중풍군과 건강인 사이에 통계적인 유의성이 나타나지 않았다(p=0.995). 결론 : 이상의 결과를 통하여 IL4R 유전자 다형성은 중풍의 발병과는 관련성이 있는 것으로 사려되지만 더 많은 환자를 대상으로 다른 환경요인 또는 유전자와의 연관성에 대한 심도있는 연구가 필요하다고 하겠다.

The effects of Helicobacter pylori and medicinal plants extract (Leweifang) on the viability and interleukin(IL)-8 production of gastric epithelial cell were investigated. Cells viability was significantly decreased when they incubated with H. pylori or H. pylori toxin. Co-incubation with Leweifang increased H. pylori or H. pylori toxin-inhibited cell growth in a concentration-dependent manner. The production of IL-8 was greatly increased in H. pylori-infected KATO III gastric epithelial cells in a concentration- and time-dependent manner. The increased production of IL-8 was significantly inhibited by Leweifang $(1,000{\sim}5,000{\mu}g/ml)$. These results indicate that Leweifang has protective effect on H. pylori-inhibited cell growth and H. pylori-induced gastric mucosal cell inflammation by suppressing the production of inflammatory cytokine (IL-8) from gastric epithelial cells.
