The hawthorn fruit (Crataegus pinnatifida Bunge var. typica Schneider) is used as a traditional medicine in Korea. The objective of this study was to understand the mechanisms of the anti-inflammatory effects of the water fractionated portion of hawthorn fruit on a lipopolysaccharide (LPS)-stimulated RAW 264.7 cellular model. The level of nitric oxide (NO) production in the water fraction and LPS-treated RAW 264.7 cells were determined with an ELISA. The cytotoxicity of the water fraction and LPS was measured with an MTT assay. Expression of nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor (TNF)-${\alpha}$, interleukin 6 (IL-6), and interleukin $1{\beta}$ (IL-$1{\beta}$) mRNA were analyzed with a reverse transcription polymerase chain reaction (RT-PCR). The water fraction of hawthorn fruit was determined to be safe and significantly inhibited NO production in LPS-stimulated RAW 264.7 cells and suppressed COX-2, (TNF)-${\alpha}$, IL-$1{\beta}$, and IL-6 expression. The observed anti-inflammatory effects of the water fraction of hawthorn fruit might be attributed to the down-regulation of COX-2, (TNF)-${\alpha}$, IL-$1{\beta}$, and IL-6 expression in LPS-stimulated RAW 264.7 cells.

Falun Gong (FG) is an advanced system of cultivation and practice, which is beneficial for both mind and body. In this study we investigated the effects of FG on the production of cytokines in FG practitioner (FGP). To study whether plasma cytokines levels were affected by FG, their levels were analyzed. The amount of $interferon-{\gamma}$ $(IFN-{\gamma})$, interleukin (IL)-2, IL-4 and IL-6 (2.5-fold for $IFN-{\gamma}$, 1.2-fold for IL-2, 2.1-fold for IL-4 and 2.5-fold for IL-6, respectively) were significantly higher in the FGP group than normal group (P<0.05). Peripheral blood mononuclear cells obtained from normal healthy control and FGP were cultured for 24 h in the presence or absence of lipopolysaccharide. The amount of $IFN-{\gamma}$, IL-2, IL-4 and IL-6 in culture supernatant was quantified. However, there were no significant differences in the level of the same cytokines between the normal and FGP group. These data suggest that FG cultivation may contribute to immune-enhancement in vivo.

Probiotics are live microorganisms that confer a health benefit on the host. Duolac-Gold is a mixture of seven probiotic bacteria containing three species of Bifidobacteria, two species of Lactobacillus, and Streptococcus thermophilus. The aim of this study was to assess the anti-inflammatory effects of Duolac-Gold in an inflammatory bowel disease (IBD) mouse model. IBD was induced by administering 1.5% dextran sulfate sodium (DSS) for 10 days. After induction of DSS-induced colitis, Duolac-Gold was orally administered at three different concentrations. Interestingly, Duolac-Gold treatment accelerated IBD healing, and anti-inflammatory activity was assessed by weight loss, length of the colon, and a microscopic damage score by histology. The expression of inflammatory related cytokines was measured in colon tissues and serum. Of these cytokines, the expression of interleukin-6 decreased remarkably after Duolac-Gold treatment. Taken together, these results suggest that Duolac-Gold treatment is effective in IBD healing by regulating IL-6.

Bifidobacteria has been suggested to exert health promoting effects on the host by maintaining microbial flora and modulating immune functions in the human intestine. We assessed modulatory effects of the different cell fractions of Bifidobacterium sp. BGN4 on macrophage cells and other immune cells from the spleen and Peyer's patches (PP) of mouse. Cell free extracts (CFE) of the BGN4 fractions induced well-developed morphological changes in the macrophages and increased the phagocytic activity more effectively than other fractions in the mouse peritoneal cells. Nitric oxide (NO) production was significantly reduced by both the cell walls (CW) and CFE in the cultured cells from the spleen and PP. The production of interleukin-6 (IL-6) and interleukin-10 (IL-10) was eminent in the spleen cells treated with experimental BGN4 cell fractions. However, in the PP cells, IL-6 was slightly decreased by the treatment with the whole cell (WC) and CW, whereas IL-10 was significantly increased by the treatment with the CW and CFE. These results suggest that different types of bifidobacterial cell fractions may have differential immunomodulatory activities depending on their location within the host immune system.

Enzyme-assisted hydrolysis is frequently used as a cost-effective and efficient method to obtain functional ingredients from bioresources. This study involved the enzyme-assisted hydrolyzation and purification of fucoidan from Ecklonia maxima stipe and the investigation of its anti-inflammatory activity in lipopolysaccharide (LPS)-induced RAW 264.7 cells. Fucoidans of Viscozyme-assisted hydrolysate from E. maxima (EMSFs) harvested in Jeju, Korea. Structural and chemical characterizations were performed using fourier transform infrared spectroscopy, scanning electron microscope, and monosaccharide analysis. Among fucoidans, EMSF6 was rich in fucose and sulfate and had a similar structural character to commercial fucoidan. EMSF6 showed a strong inhibitory effect on nitric oxide generation in LPS-induced RAW 264.7 cells and significantly decreased the production of LPS-induced pro-inflammatory cytokines, including interleukin-6, interleukin-1β, and tumor necrosis factor α. The anti-inflammatory potential of EMSF6 was mediated through the downregulation of inducible nitric oxide synthase and cyclooxygenase-2 expression. Thus, fucoidans from E. maxima stipe are promising candidates for functional food products.

스트레스가 위장관 기능을 변화시키며 이에는 interleukin과 시상하부-뇌하수체-부신피질 축이 관여한 다고 알려져 있다. 한편 우울증이 기능성 위장관 장애 및 interleukin과 연관성을 지닌다. 본 연구에서는 IL-$1\beta$, IL-2, IL-6의 혈청 농도를 기능성 위장관 장애 환자에서 측정하고, 혈청 cortisol 및 우울증과 스트레스의 정도를 조사하여 기능성 위장관 장애에 있어서 interleukin의 역할과 우울증 및 스트레스와의 상관성을 살펴보고자 하였다. 방법: 기능성 위장관 장애의 진단을 위한 로마기준 II에 따라 진단된 환자 20명과 건강한 대조군 20명을 대상으로 하였다. 채취한 혈액에서 혈청을 분리한 다음 Enzyme-linked Immunosorbent Assay 방법으로 혈청 IL-$1\beta$, IL-2, IL-6 농도를 측정하고 Fluorescence Polarization Immunoassay 방법으로 혈청 cortisol 농도 를 측정하였다. 우울증상의 정도를 Hamilton Rating Scale for Depression을 이용하여 평가하고, Schedule of Recent Experience를 이용하여 최근 일년간의 스트레스 생활사건의 양을 측정하여 비교하였다. 결과는 다음과 같다. 결과: 1) 기능성 위장관 장애 환자들의 혈청 IL-$1\beta$, IL-2 농도는 대조군에 비해 유의하게 낮았으나 혈청 IL-6 농도는 차이가 없었다. 2) 기능성 위장관 장애 환자군의 혈청 cortisol 농도는 대조군에 비해 유의하게 높았고, 우울증상도 유의하게 더 심하였으며, 스트레스 생활사건의 양 또한 유의하게 더 많았다. 3) 기능성 위장관 장애에서 우울증상의 정도와 혈청 cortisol 간에는 유의한 정상관관계가 있었다. 정도는 IL-$1\beta$와 역상관하는 경향이 있고, IL-2와는 정상관하였다. 스트레스 생활사건의 양파 혈청 cortisol 농도는 IL-6 와 유의하게 정상관하였다 대조군을 포함한 전 집단에서 IL-$1\beta$는 우울 정도, 스트레스 생활사건의 양, 혈청 cortisol 등과 유의하게 역 상관하였다. IL-6와 의하게 정상관하였다. 결론: 기능성 위장관 장애는 우울증 및 스트레스와 연관되며, 우울증, 스트레스가 심할수록 혈청 cortisol이 높았다. 기능성 위장관 장애 환자들에서 IL-$1\beta$, IL-2가 감소되어 있었지만, IL-6는 변화가 없었다. 상대적으로 증가된 혈청 cortisol이 IL의 변화와 관련될 수 있다고 생각된다.

The interleukin-1 receptor antagonist (IL-1RA) is a potential stroke treatment candidate. Intranasal delivery is a novel method thereby a therapeutic protein can be penetrated into the brain parenchyma by bypassing the blood-brain barrier. Thus, this study tested whether intranasal IL-1RA can provide neuroprotection and brain penetration in transient cerebral ischemia. In male Sprague-Dawley rats, focal cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) for 1 h. The rats simultaneously received 50 mg/kg human IL-1RA through the intranasal (IN group) or intraperitoneal route (IP group). The other rats were given 0.5 mL/kg normal saline (EC group). Neurobehavioral function, infarct size, and the concentration of the administered human IL-1RA in the brain tissue were assessed. In addition, the cellular distribution of intranasal IL-1RA in the brain and its effect on proinflammatory cytokines expression were evaluated. Intranasal IL-1RA improved neurological deficit and reduced infarct size until 7 days after MCAO (p<0.05). The concentrations of the human IL-1RA in the brain tissue 24 h after MCAO were significantly greater in the IN group than in the IP group (p<0.05). The human IL-1RA was confirmed to be co-localized with neuron and microglia. Furthermore, the IN group had lower expression of $interleukin-1{\beta}$ and tumor necrosis $factor-{\alpha}$ at 6 h after MCAO than the EC group (p<0.05). These results suggest that intranasal IL-1RA can reach the brain parenchyma more efficiently and provide superior neuroprotection in the transient focal cerebral ischemia.
