  • Bamboo salt has been used for the purpose of prevention and treatment of various diseases in Korea. Present study was carried out to ascertain the effects of purple bamboo salt upon anti-allergic effect, anti-inflammatory activity and immune-enhance effect as well. Purple bamboo salt significantly inhibited the ear swelling response and histamine release induced by compound 48/80 in mice and rat peritoneal mast cells. Purple bamboo salt (0.01 ∼ lg/kg) also dose-dependently inhibited the passive cutaneous anaphylaxis by oral administration. Purple bamboo salt (1 mg/mL) in hibited phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-1${\beta}$ and IL-6 secretion, by 67.04${\pm}$0.08%, 68.01${\pm}$1.85%, 69.48${\pm}$0.54%, respectively. In addition, purple bamboo salt inhibited the expression of TNF-${\alpha}$ mRNA in HMC-1 cells. Finally, we investigated the effect of purple bamboo salt in the forced swimming test (FST) and the change of purple bamboo salt-mediated cytokine production from MOLT-4 cells. At the 7th, immobility time was significantly decreased in the purple bamboo salt-administration group (35.4 ${\pm}$5.9 s for 1 g/kg) in comparison with the control group (93.2 ${\pm}$ 15.45). After FST, the content of glucose in the blood serum was increased and the levels of blood urea nitrogen, lactic dehydrogenase was decreased in purple bamboo salt-administration group. However, it had no effect on the elevation of CK and TP level. Purple bamboo salt (1 mg/mL) significantly increased the interferon (IFN)-${\gamma}$ and IL-2 level compared with media control (about 3.7-fold for IFN-${\gamma}$, about 3.5-fold for IL-2, p〈0.05) but did not affect the IL-4.

  • The ability of nematodes to manipulate the immune system of their host towards a Th2 and T regulatory responses has been proposed to suppress the inflammatory response. Clinical trials have proposed a useful effect of helminth infections on improvement of inflammatory disorders. In this study, we investigated the immunomodulatory effect of Syphacia obvelata infection to induce intestinal tolerance in C57BL/6 mice. Mice were infected through the cagemates with self-infected BALB/c mice. Four weeks post-infection, expression levels of $IFN-{\gamma}$, $TNF-{\alpha}$, IL-17, and IL-10 were assessed in the supernatant of mesenteric lymph node (MLN) culture. $Foxp3^+Treg$ were measured in MLN cells by flow cytometry. In the S. obvelata-infected group, the percentage of Tregs ($5.2{\pm}0.4$) was significantly higher than the control ($3.6{\pm}0.5$) (P<0.05). The levels of IL-10 ($55.3{\pm}2.2$ vs $35.2{\pm}3.2$), IL-17 ($52.9{\pm}3.8$ vs $41{\pm}1.8$), $IFN-{\gamma}$ ($44.8{\pm}4.8$ vs $22.3{\pm}2.3$) and $TNF-{\alpha}$ ($71.1{\pm}5.8$ vs $60.1{\pm}3.3$) were significantly increased in infected mice compared to the control group (P<0.05). The above results showed the potential effects of S. obvelata to induce intestinal tolerance. Therefore, it seems that S. obvelata may increase the immunological suppressive function in the intestinal tract.

  • 본 연구는 홍삼추출물(홍삼단)과 생약복합추출물(헤모힘)이 주요 기능성분은 다르지만 면역활성이라는 생리활성 측면에서 동일한 효과를 인정하고 있어서 이들의 병용 처리가 면역세포에 어떠한 영향을 미치는지에 대해 알아보기 위하여 수행되었다. 면역활성능에 관한 평가를 진행하기 위하여 마우스의 골수에서 분리한 미분화 골수세포를 선천면역에서 중요한 역할을 수행하는 대식세포 및 수지상세포로 분화시킨 후 홍삼추출물과 생약복합추출물을 병용 처리하였을 때 대식세포 및 수지상세포의 세포 증식능 및 사이토카인의 분비능이 증가되는 것으로 관찰되었다. 또한 활성화된 탐식(면역)세포의 세포 표면에서 발현되는 CD80과 CD86의 발현과 탐식(면역)세포의 항원제시에 밀접한 관련이 있는 주 조직적합성 복합체(MHC class II)의 발현이 홍삼추출물과 생약복합추출물의 병용 처리구에서 유의적으로 증가되는 것으로 관찰되었다. 또한 후천면역에서 중요한 역할을 수행하는 면역 T 세포가 다량으로 분포하는 비장 조직으로부터 비장세포를 분리하여 홍삼추출물과 생약복합추출물을 병용처리하였을 때 세포 증식능 및 면역활성을 유도하는 Th1 세포가 분비하는 사이토카인의 함량이 증가되는 것으로 나타났다. 이러한 결과로 미루어 볼 때 홍삼추출물과 생약복합 추출물의 병용 처리는 선천면역뿐만 아니라 후천면역에 관여하는 다양한 면역세포의 활성화에 직 간접적으로 다양한 상승작용을 미치는 것으로 사료된다.

  • 본 연구에서는 오리나무유래 HST의 T 세포 비활성화 효능을 확인하고 그 기전을 탐색하여 새로운 항아토피 천연소재로의 개발 가능성을 제시하고자 하였다. HST는 T 세포 mitogen으로서 anti-CD3 mAb가 처리 된 마우스 비장에서 Th 사이토카인(IL-2, IFN-${\gamma}$, IL-4, IL-5, IL-10)의 발현을 효과적으로 억제하였으며, T 세포 early activation marker인 CD25 유전자 발현이 INCA-6에서 매우 효과적으로 억제되는 것으로 보아, NFAT inactivator-유사 NFAT 탈인산화 억제 기전을 가지는 것으로 예측되었다. 또한 세포주기조절 단백질인 p21과 p27의 유전자도 HST에 의해 upregulation이 되어 효과적인 T 세포 증식 및 분화를 억제할 것으로 생각되었다. 이러한 세포주기조절 효과는 AD를 악화시키는 세균인 S. aureus 성장억제 실험에서 확인되어 향후 항박테리아 효능을 갖는 우수한 항아토피피부염 천연소재로서 HST의 활용 가치가 높을 것으로 판단된다.

  • 본 연구는 꾸지뽕 잎으로부터 추출된 다당류인 CTP의 처리가 면역세포의 활성에 미치는 영향에 관하여 평가하였다. CTP는 에탄올 침전법에 의하여 추출하였고, 면역 활성능의 평가는 대식세포주인 RAW 264.7 세포와 미분화 골수세포로부터 유도 분화시킨 대식세포 및 마우스 비장으로부터 유리시킨 비장세포에 CTP를 농도별로 처리하여 관찰하였다. 선천면역계에서 중요한 역할을 수행하는 대식세포에 CTP를 처리하였을 때 세포 증식률, NO 및 cytokine 분비능이 CTP 처리 농도 의존적으로 증가하는 것으로 관찰되었을 뿐만 아니라 비장세포에서도 이와 유사하게 세포 증식률이 증가하고 Th 1 type의 cytokine 분비능 또한 유의적으로 증가하는 것으로 관찰되었다. 이상의 결과로 미루어보아 꾸지뽕다당류 추출물인 CTP는 다양한 면역세포의 활성을 증가시키는 것으로 생각하며 이를 활용하여 다양한 식품 및 건강보조식품을 개발한다면 그 경제적 가치가 매우 클 것으로 생각한다.

  • Objectives : There is a pressing need to determine the clinical and scientific validity of herbal therapies for animal model with atopic dermatitis since some differences in systemic cytokine polarization between in animal model and in patients with atopic dermatitis has been reported. New studies for tang, medicinal herb itself or effective ingradients of medicinal herb showing anti-atopic dermatitis effectiveness are reviewed in terms of cytokine regulation. Methods : Those herbal therapies used to treat atopic dermatitis in animal model were introduced and the expression pattern of cytokine and the activity of mast cell were compared in both animal model and patients with atopic dermatitis. Results : In case of atopic dermatitis in human, there is a biphasic pattern of cytokine expression in atopic dermatitis, with acute skin inflammation associated with a predominance of IL-4 and IL-13 expression from Th2 cells, and chronic inflammation associated with increased IL-5 from Th2-cells and IFN-${\gamma}$ from Th1-cells. However, a pattern of cytokine expression in animal model with atopic dermatitis is not matched well to the biphasic pattern of cytokine expression in patients with atopic dermatitis. In addition, a kind of cytokine is different by animal model with atopic dermatitis. These differences would make herbal medicines, showing their effectiveness on atopic dermatitis, difficult to apply to patients with atopic dermatitis. Conclusion : The pattern of local cytokine expression plays an important role in modulating tissue inflammation, and in atopic dermatitis this pattern depends on the acuity or duration of the skin lesion. Thus, in order to develop medicinal herb itself or effective ingradients of medicinal herb showing anti-atopic dermatitis effectiveness, biphasic pattern of cytokine expression should be considered in animal model with atopic dermatitis.

  • Objective: The purpose of experimental study was to prove the effects of Boyangmakseong-bang (BYMSB) treatment on cBSA-induced in a MN mouse model. Methods: We divided mice into 4 groups. The Normal group had no treatment. We used cBSA and induced MN mouse model to the other 3 groups. The Control group was treated with cBSA (9mg/kg i.p) only. The second group, named 'BY-250', was treated with cBSA (9mg/kg i.p) and BYMSB extract (250mg/kg, p.o). The third group, named 'BY-500', was treated with cBSA (9mg/kg i.p) and BYMSB extract (500mg/kg, p.o). After cBSA and BYMSB extract treatment for 4 weeks, the increase in percentage of body weight, proteinuria, serum albumin, total cholesterol, creatinine and BUN of all groups were measured. The CD3+, CD19+, CD4+, CD8+ cell levels of spleen of all groups were analyzed. IgA, IgG, IgM, IL-$1{\beta}$, TNF-${\alpha}$, IL-6 and IFN-${\gamma}$ levels of all groups were gauged. H&E staining, immunofluorescence staining and electron microscopy of kidney were observed. Results: BYMSB showed significant decrease in the 24hrs proteinuria, serum total cholesterol, serum IgG levels and BUN levels, and showed significant increase in the serum albumin levels compared with the control group. BYMSB showed increase in the increasing percentage of body weight and IFN-${\gamma}$ levels compared with the control. BYMSB showed decrease in the CD3+ T cells, CD4+ Th cells, IL-$1{\beta}$, TNF-${\alpha}$ and IL-6 levels, but did not show significant change compared with the control. BYMSB showed considerable decrease in the thickening of the GBM on H&E staining, deposition of IgG on immunofluorescence staining and deposition of electron-density on electron microscopy of kidney compared with the control. Conclusions: According to the above results, it is suggested that BYMSB decreases the symptoms of MN induced by cBSA in a mouse model. Therefore BYMSB seems to be applicable to MN in clinical practice.

  • Anti-inflammatory potential of the enzymatic extract prepared by Kojizyme (ECK), a component of brown seaweeds Ecklonia cava (Alariaceae, Phaeophyta) in vivo was investigated. For the application of mouse ear edema model, 12-O-tetradecanoylphorbol acetate (TPA) was used, a topical inducer of a long-lasting inflammatory response. Our results demonstrated that ECK inhibited ear edema when topically applied to mouse ear skin. In histological evaluation, the inhibition activity of ECK on TPA-induced inflammation is similar to that of dexamethasone, although less strong. In addition, the mRNA expression levels of IL-$1{\beta}$, IFN-$\gamma$, TNF-$\alpha$, and cyclooxygenase-2 (COX2) and the immunoreactivity to inducible nitric oxide synthase (iNOS) and COX2 expressed mainly in inflammatory cells were down-regulated by ECK. These results indicate that ECK has anti-inflammatory effects through the inhibition of Th1 cytokines and 2 inducers of inflammation in TPA-induced ear skin edema.

  • Ginsan, a polysaccharide isolated from Panax ginseng, has been shown to be a potent immunomodulator, producing a variety of cytokines such as TNF-a, IL-1$\beta$, IL-2, IL-6, IL-12, IFN-${\gamma}$ and GM-CSF, and stimulating lymphoid cells to proliferate. In the present study, we analyzed some immune functions 1$^{st}$-5$^{th}$ days after ginsan i.p. injection, including the level of non-protein thiols (NPSH) as antioxidants, heme oxygenase (HO) activity as a marker of oxidative stress, zoxazolamine-induced paralysis time and level of hepatic cytochrome P-450 (CYP450) as indices of drug metabolism system, and activities of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin, and albumin level as indicators of hepatotoxicity. Ginsan in the dose of 100 mg/kg caused marked elevation (1.7-2 fold) of HO activity, decrease of total CYP450 level (by 20-34%), and prolongation of zoxazolamine-induced paralysis time (by 65-70%), and showed some differences between male and female mice. Ginsan treatment did not seem to cause hepatic injury, since serum AST, ALT, and ALP activities and levels of total bilirubin and albumin were not changed.d.
