  • Water extracts of Acanthopanax divaricatus var. albeofructus (ADA) fruits were used to treat hPBMC to determine the mechanisms for the immunomodulatory effects. The secretion level of various cytokines including Th-1 type (IL-2, L-12, $IFN-{\gamma}$ and $TNF-{\alpha}$) and Th-2 type (IL-6, IL-8 and IL-10) were measured using ELISA. A significant increase of Th-1 type cytokine secretion was observed in the presence of extract while Th-2 cytokine, IL-6 was suppressed. Our results suggest that ADA fruit extract may influence the anticancer immune responses towards a predominance of Th-1 cytokines in the immune system.

  • Objectives : On an experimental basis, the effects of atopic dermatitis induced materials on the expression of cytokine genes in human monocytes (THP-1, U937) and mast cells were studied. This study was carried out to be considered a fundamental knowledge in the research on the good of oriental medicine. Methods : After culturing THP-1, U937, and HMC-1, with the three different concentrations of LPS ($1\;{\mu}g/ml$), DPE ($10\;{\mu}g/ml$), and DNCB ($1\;{\mu}g/ml$), atopic dermatitis induced materials were treated in the culture medium. To investigate cytokine genes expression patterns, with lysis buffer and separation reagent, total RNA was extracted from THP-1, U937, and HMC-1 at intervals of 0, 12, 24, and 48 hours. Both cytokine mRNA expression patterns by atopic dermatitis induced materials and change of cytokine genes expression patterns in relation to atopy by selenium were analyzed with RT-PCR. Also IL-4 and INF-$\gamma$, which were secreted in the HMC-1, were analyzed using ELISA method. Results : 1. After treating THP-1 and U937 with LPS, DPE, and DNCB, there was no significant change in cytokine genes themselves, but various cytokines (IL-4, IL-6, IL-8, IL-13, IFN-$\gamma$, IFN-a, MCP-1, B2-MG) were expressed. 2. In the case of HMC-1, the expressions of IL-6 and IL-8 were significantly increased in the analysis of mRNA expression by dust mite allergens in DPE. 3. As a result of ELISA method, it is certain that IL-4 and IFN-$\gamma$ protein were secreted in the HMC-1 by DPE. 4. Selenium, an essential trace element, decreased the IL-10 and IL-13 expression in the HMC-1 by DPE. Conclusion : The results suggest that it is necessary to choose proper atopic dermatitis induced materials and suitable cultured cells in establishment of in vitro model of atopic dermatitis.

  • Theobroma cacao L., a fruit of cacao trees, is a perennial plant, which belongs to Sterculiaceae, and is native to the Amazon in South Africa. It also has been known for its various biologically active effects, such as anti-oxidation, anti-cancer, and anti-bacterial. The spleen cell proliferations of mice were measured at 48 hours after treatment of Theobroma cacao L. water extracts in seven concentrations(0, 5, 10, 50, 100, 250, 500 and 1,000 ㎍/mL) an ELISA assay. The production of cytokine (IL-1β, TNF-α, IFN-γ), is secreted by macrophages stimulated with LPS, was detected by ELISA assay using the cytokine kit. From the results of in vitro study, both splenocytes and cytokine production activated by peritoneal macrophages have increased when water extracts were supplemented in the range between 250 and 500 ㎍/mL concentration. Notably, splenocytes production has a signigicant proliferation at 500 ㎍/mL concentration. The result from this research suggests that supplementation with Theobroma cacao L. water extracts may enhance the immune function by stimulating the splenocyte proliferation and improving the cytokine production activating macrophage in vitro.

  • This experiment was performed to examine the in vitro and in vivo affects of the two different haplotype strains of mice, BALB/c and C3H/HeN infected with Echinostoma hortense, and the manifestation of the profiles of cytokine in the splenocytes. In the in vitro experiment, the two mice's splenocytes were divided and stimulated with antigen of crude extracts and the antigen of excretory and secretory products of an adult warm and the manifestation of cytokine mRNA was verified with RT-PCR. As a result, the two different strains of mice both strongly manifested the Th2 cytokine rather than the Thl cytokine and in the case of the Th2 cytokine, the BALB/c mice manifested more strongly than the C3H/HeN mice. In the experiment using the ELISA method, the protem cytokine manifestation had the same result as the mRNA experiment. In the in vivo experiment, the mice was infected via oral route with the metacercaria of the Echinostoma hortense and the manifestation of cytokine was verified by RT-PCR and ELISA and the results were the same as the in vitro experiment. Therefore, in the two strains of BALB/c and C3H/HeN, the C3H/HeN showed a higher susceptivity to the Echinostoma hortense.

  • In vitro 실험을 통한 느타리버섯 물 추출물 첨가가 마우스의 면역세포 증식에 미치는 영향에 대한 연구 결과, 음의 대조군에 비해 느타리 물 추출물을 첨가한 모든 농도에서 비장세포 증식능이 증가하였으며, 특히 $100{\sim}1,000{\mu}g/mL$ 농도에서 유의적으로 증가하였다. 반면, 사이토카인 생성의 경우, IL-2, IFN-${\gamma}$, TNF-${\alpha}$ 사이토카인 생성량을 측정한 결과, 느타리버섯 물 추출물 $50{\sim}500{\mu}g/mL$ 농도에서 생성된 IL-2, IFN-${\gamma}$, TNF-${\alpha}$ 사이토카인은 대조군보다 높은 생성량을 보였다. IFN-${\gamma}$, TNF-${\alpha}$ 사이토카인 모두 50, 100, 250, $500{\mu}g/mL$의 농도에서 높은 생성량을 나타내었다. IL-2의 경우, 생성량이 유의적인 차이는 보이지 않았지만, $50{\mu}g/mL$ 이상에서 증가하는 경향을 보여주었다. 이상의 결과에 의하면 느타리버섯 물 추출물은 마우스 비장 세포를 증식시키고, 사이토카인 생성량에도 영향을 주어, 면역 기관의 주요 기능을 증진시킬 가능성이 있을 것으로 사료되며, 느타리버섯이 면역 증진 기능성 식품 개발의 소재로 활용될 가능성이 있을 것으로 기대된다.

  • 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.

  • The capacities of bacterial DNA, extracted from Salmonella typhimurium, and lipopolysaccharide (LPS), extracted from Salmonella minnesota, to activate mouse peritoneal macrophages in vitro were compared. Activation was assessed by estimating e levels of 3 cytokines, IL-10, IL-12, and $IL-1{\beta}$, at time intervals of 3, 6, 9, and 24 h after addition of LPS and/or DNA to macrophage cultures. Cytokine levels in culture supernatants were determined by enzyme-linked immunosorbent assay (ELISA) and cytokine mRNA levels were estimated based on band intensity in cultured cells by reverse transcriptase-polymerase chain reaction (RT-PCR). Results obtained demonstrated the ability of DNA and LPS to elicit increased production of all 3 cytokines as compared to controls. In the amount tested, LPS appeared to be a more potent inducer of IL-12, and $IL-1{\beta}$, whereas DNA induced higher levels of IL-10. DNA and LPS, used in combination, exhibited neither an additive nor a synergistic effect. Rather, an antagonist effect appeared to occur. RT-PCR results correlated well with ELISA.

  • 유색미 겨 추출물이 염증반응에 미치는 효과를 호중구 세포주 및 비만세포가 분비하는 염증매개물질인 histamine과 ${\beta}-hexosaminidase$의 분비 및 염증 cytokine 생성에 대한 억제활성을 측정하여 평가하였다. 호중구 세포주인 RBL-2H3 세포와 rat에서 분리 추출한 복강 비만세포(RPMC, peritoneal mast cell)를 이용하여 histamine과 ${\beta}-hexosaminidase$ 분비에 대한 억제활성을 조사한 결과, 일반미 겨 추출물은 RBL-2H3 세포에서 염증매개물질들의 분비량을 증가시킨 반면, 유색미 겨 추출물은 이들의 분비를 억제하였다(histamine 10.19% 억제, ${\beta}-hexosaminidase$ 110.03% 억제). RPMC에서는 유색미가 histamine과 ${\beta}-hexosaminidase$의 분비를 일반미보다 각각 8배와 3배나 높게 억제하는 것으로 나타났다. 염증관련 cytokine으로서 $IL-1{\beta},\;TNF-{\alpha}$ 및 IL-6의 발현을 RT-PCR로 측정한 결과, 유색미가 일반미 보다 $TNF-{\alpha},\;IL-1{\beta}$ 및 IL-6의 발현을 억제하는 효과가 우수하였다. ELISA를 이용하여 cytokine의 분비량을 측정한 실험에서도 유색미가 일반미보다 $TNF-{\alpha},\;IL-1{\beta}$ 및 IL-6의 분비를 효과적으로 억제하였다. 이상의 결과는 유색미가 염증반응의 원인 물질인 histamine과 ${\beta}-hexosaminidase$의 분비에 대한 억제효과 뿐 아니라, 염증 cytokine의 발현을 저해하는 효과도 일반미보다 우수하다는 사실을 보여주었다.
