아토피 피부염에서 유산균의 유익성에 대해서는 이미 많이 알려져 있고 우리나라 전통식품인 김치유산균의 유익성에 대한 연구도 많이 진행되었으나 아토피 피부염에서 김치 유산균의 효과에 관한 연구는 아직 미비한 실정이다. 본 연구에서는 아토피 동물 모델인 NC/Nga mice에 김치유산균에서 추출한 유산균(L.plantarum K8)의 파쇄물과 유산균 및 ${\gamma}$-리놀렌산 복합체(L.rhamnosus GG 생균, B. lactis Bb-12Lb 생균, L. plantarum K8생균, L. plantarum K8 파쇄물, ${\gamma}$-리놀렌산)를 경구 투여한 후 혈청 면역지표(IgE, IL-4, IL-5, IFN-${\gamma}$)와 비장 배양액에서 IgE 농도를 측정하였다. 실험동물의 체중 및 사료섭취량은 사육기간이 지남에 따라 증가하는 경향을 보였으며 각 군 간에 유의적인 차이는 관찰되지 않았다. 실험 시작 시 혈청 IgE 농도는 각 군 간에 차이가 나타나지 않았으나 실험 전 기간 4주 동안 유산균 파쇄물(DPF), 유산균 및 ${\gamma}$-리놀렌산 복합체(DPOC), 항히스타민(DAH)을 섭취한 군에서 증류수(DDW)만을 섭취군에 비하여 유의적으로 낮게 나타났다. 혈청 IFN-${\gamma}$ 농도는 각 군에서 유의적인 차이가 나타나지 않았으나 혈청 IL-4 농도는 유산균 및 ${\gamma}$-리놀렌산 복합체를 섭취한 군(DPOC)에서 대조군에 비하여 유의적으로 낮게 나타났다. 혈청 IL-5 농도는 유산균 파쇄물(DPF), 유산균 및 ${\gamma}$-리놀렌산 복합체(DPOC), 항히스타민(DAH)을 섭취한 군에서 모두 대조군에 비하여 유의적으로 낮았다. 비장 임파구 배양 상층액의 IgE 농도는 각 군에서 군 간 유의적인 차이가 나타나지 않았다. 결론적으로, 아토피 동물모델 NC/Nga mice에 유산균 파쇄물(DPF)과 유산균 및 감마리놀렌산 복합체(DPOC)의 경구투여는 혈청 IgE, IL-4, IL-5를 감소시키는 것으로 나타났으며, 김치로부터 추출한 프로바이오틱스를 아토피 환자에게 섭취시켰을 때 IgE, IL-4, IL-5 감소와 같은 긍정적인 효과를 볼 수 있을 것으로 기대한다. 여러 종류의 프로바이오틱스는 아토피의 증상완화 또는 면역 체계에 미치는 영향과 정확한 메카니즘을 밝히기 위하여 과학적인 연구가 필요한 것으로 사료된다.

Objective: To investigate the effect of intraoperative glucose fluctuation and postoperative interlukin-6 (IL-6), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), C-reactive protein (CRP) levels on the short-term prognosis of patients with intracranial supratentorial neoplasms. Materials and Methods: Eighty-six patients undergoing intracranial excision were selected in The Second Hospital of Jilin University. According to the condition of glucose fluctuation, the patients were divided into group A (glucose fluctuation <2.2 mmol/L, n=57) and group B (glucose fluctuation ${\geq}2.2mmol/L$, n=29). Glucose was assessed by drawing 2 mL blood from internal jugular vein in two groups in the following time points, namely fasting blood glucose 1 d before operation ($T_0$), 5 min after anesthesia induction ($T_1$), intraoperative peak glucose ($T_2$), intraoperative lowest glucose ($T_3$), 5 min after closing the skull ($T_4$), immediately after returning to intensive care unit (ICU) ($T_5$) and 2 h after returning to ICU ($T_6$). 1 d before operation and 1, 3 and 6 d after operation, serum IL-6 and TNF-${\alpha}$ levels were detected with enzyme-linked immunosorbent assay (ELISA), and CRP level with immunoturbidimetry. Additionally, postoperative adverse reactions were monitored. Results: There was no statistical significance between two groups regarding the operation time, anesthesia time, amount of intraoperative bleeding and blood transfusion (P>0.05). The glucose levels in both groups at $T_1{\sim}T_6$ went up conspicuously compared with that at $T_0$ (P<0.01), and those in group B at $T_2$, $T_4$, $T_5$ and $T_6$ were significantly higher than in group A (P<0.01). Serum IL-6, TNF-${\alpha}$ and CRP levels in both groups 1, 3 and 6 d after operation increased markedly compared with 1 d before operation (P<0.01), but the increased range in group A was notably lower than in group B (P<0.05 or P<0.01). Postoperative incidences of hypoglycemia, hyperglycemia and myocardial ischemia in group A were significantly lower than in group B (P<0.05), and respiratory support time obviously shorter than in group B (P<0.01). Conclusions: The glucose fluctuation of patients undergoing intracranial excision is related to postoperative IL-6, TNF-${\alpha}$ and CRP levels and those with small range of glucose fluctuation have better prognosis.

Betulinic acid (BA), a pentacyclic triterpene isolated from Lycopus lucidus, has been reported to be a selective inducer of apoptosis in various human cancer and shown anti-inflammatory and immunomodulatory properties. We postulated that BA modulates the immunomodulatory properties at least two groups of protein mediators of inflammation, interlukin-1$\beta$ (IL-1$\beta$) and the tumor necrosis factor- $\alpha$ (TNF-$\alpha$) on the basis of the critical role of the monocytes and tissue macrophages in inflammatory and immune responses. TNF-$\alpha$ and IL-1$\beta$ were produced by BA in a dose dependent manner at concentration of 0.625 and 10 $\mu$g/mL. The production of NO associated with iNOS was inhibited when treated with LPS at the concentration of 2.5 to 20 $\mu$g/mL of BA whereas COX-2 expression was decreased at 2.5 to 20 $\mu$g/mL. These modulations of inflammatory mediators were examined in LPS-stimulated RAW 264.7 cells and peritoneal macrophages. The morphology of macrophage was also examined and enhanced surface CD 40 molecule was expressed when treated BA at 0.625∼5 $\mu$g/mL with or without LPS. Furthermore, BA (20 $\mu$g/mL) enhanced apoptosis by producing DNA ladder in the RAW 264.7 cells. Our results indicated that BA induced activation of macrophage and pro-inflammatory cytokines. This may provide a molecular basis for the ability of BA to mediate macrophage, suppress inflammation, and modulate the immune response.

This study was performed to determine the effects of $\gamma$-irradiation on the antiallergic activity of alginate. An alginate aqueous solution was $\gamma$-irradiated at 3, 5, 7, 10, 20, and 100 kGy. First, the molecular weight (Mw) of alginate rapidly decreased as the $\gamma$-irradiation dose increased up to 20 kGy. Then, the antiallergic activity of the $\gamma$-irradiated alginate was measured. Interlukin (IL)-4 cytokine and IgE level were significantly decreased in the $\gamma$-irradiated alginate groups as compared to the control group in vitro. The mice intraperitoneally administered with the $\gamma$-irradiated alginate exhibited lower ovalbumin-specific IgE and IgG1 level in serum than the control mice. Furthermore, the $\gamma$-irradiated alginate suppressed total and ovalbumin-specific IgE secretions in the splenocytes. Increased IL-2 level was observed in the culture supernatants of the splenocytes that were obtained from the mice administerd with the $\gamma$-irradiated alginate, while IL-4 level decreased. The present study indicates that $\gamma$-irradiated alginate can suppress allergy in a mouse allergy model.

We previously reported that anti-inflammatory properties of poncirin, isolated from fruit of Poncirus trifoliata, might be the result from the inhibition of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis $factor-{\acute{a}}$ ($TNF-{\alpha}$) and interlukin-6 (IL-6) expression via the down-regulation of $NF{-\kappa}B$ binding activity. In this study, we investigated whether poncirin has an inhibitory effect on the production of pro-inflammatory mediators ex vivo and whether poncirin could relieve the symptoms of dextran sulfate sodium (DSS)-induced colitis in mice model of inflammatory bowel disease. Poncirin significantly inhibited the productions of NO, IL-6 and $TNF-{\alpha}$ in lipopolysaccharide (LPS)-induced mouse peritoneal macrophage. In addition, poncirin-treated mice when compared to control mice not receiving treatment recovered better from the weight loss caused by DSS-induced colitis. Changes in disease activity index (DAI) of poncirin-treated mice were also more favorable than for control mice and were comparable with mice treated with a typical anti-inflammatory-drug, 5-aminosalichylic acid (5-ASA). In addition, suppression of plasma NO and IL-6 productions of poncirin-treated mice was also observed in DSS-induced colitis. These results suggest that poncirin has potentially useful anti-inflammatory effects mediated by suppression of inflammatory mediator productions.

This study evaluated the effects of $\gamma$-irradiation on immunomodulating properties and structural changes of ${\beta}$-glucan. ${\beta}$-Glucan solutions (10 mg/mL) were ${\gamma}$-irradiated at 10, 30, and 50 kGy. Splenocyte proliferation and cytokine (interferon-${\gamma}$ and interlukin-2) productions by ${\gamma}$-irradiated ${\beta}$-glucan were evaluated in in vivo and in vitro, and structural changes of ${\beta}$-glucan were also determined after ${\gamma}$-irradiation. ${\gamma}$-Irradiation on ${\beta}$-glucan at 50 kGy enhanced splenocyte proliferation and cytokine productions, (p<0.05) and cleft glycosidic bonds of ${\beta}$-glucan resulting in lower the molecular weight. These results indicate that the use of ${\gamma}$-irradiation on ${\beta}$-glucan may be useful for improving its immunological activity by lowering the molecular weight of ${\beta}$-glucan.

Obesity is considered a mild inflammatory state, and the secretion of inflammation-related cytokines rises as adipose tissue expands. Inflammatory cytokines, including tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interlukin 6 (IL-6) and monocyte-chemoattractant protein 1 (MCP-1), are modulated by adipose tissue and known to play an important role in insulin resistance which is the common characteristics of obesity related disorders. In this study we analyzed the effects of Sasa borealis leaves extract on inflammatory cytokines and insulin resistance in diet induced obese C57/BL6J mice. The obese state was induced by a high fat diet for 20 weeks and then the mice were divided into two groups; obese control group (OBC, n = 7) and experimental group (OB-SBE, n = 7). The OBC group was fed a high fat diet and the OB-SBE group was fed a high fat diet containing 5% Sasa borealis leaves extract (SBE) for 12 weeks. We also used mice fed a standard diet as a normal control (NC, n = 7). The body weight and adipose tissue weight in the OB group were significantly higher than those in the NC group. The effects of the high fat diet were reduced by SBE treatments, and the body weight and adipose tissue deposition in the OB-SBE group were significantly decreased compared to the OBC group. The OBC group showed higher serum glucose and insulin levels which resulted in a significant increase of incremental area under the curve (IAUC) and HOMA-IR than the NC group. Also, serum leptin, TNF-${\alpha}$, and IL-6 levels were significantly higher in the OBC group than in the NC group. In contrast, the OB-SBE group showed a reversal in the metabolic defects, including a decrease in glucose, insulin, IAUC, HOMA-IR, TNF-${\alpha}$, IL-6 and leptin levels. These results suggest that BSE can suppress increased weight gain and/or fat deposition induced by a high fat diet and theses effects are accompanied by modulation of the inflammatory cytokines, TNF-${\alpha}$ and IL-6 secretion resulting in improved insulin resistance.
