Objectives : This study was designed to investigate the effects of SuJeom-san(SJS) extract in rats with caerulein-induced acute pancreatitis (AP). Methods : We examined changes of pancreatic weight, histological, immunohistochemical and gene expression of cyclooxygenase (COX-2). Thirty-six adult male Sprague-Dawley rats were divided into six groups as follow: normal(Nor), caerulein-induced (Con), caerulein + cefotaxime sodium(CT), caerulein + SJS 3 mg/kg(SJSA), caerulein + SJS 6 mg/kg(SJSB) and caerulein + SJS 12 mg/kg(SJSC) groups. Pancreatic tissues of rats from all groups were removed for histological observation and light, and electron microscopic examination. Platelet activating factor(PAF) and Interleukin-6(IL-6) levels were determined spectrophotometrically. Results : The ratio of pancreas/body weight was significantly(p<0.05) increased in the Con compared with Nor, but significantly(p<0.05) decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Caerulein administration significantly increased(p<0.05) the levels of amylase, but SJSA, SJSB, SJSC and CT significantly(p<0.05) reduced the levels of these enzymes. The levels of platelet activating factor(PAF) increased in Con compared with Nor, but decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Interleukin-6(IL-6) levels increased significantly in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The levels of tumor necrosis factor(TNF)-${\alpha}$ levels increased in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The COX-2 positive materials were observed in the pancreas of the Con, but these positive materials were decreased in the SJS extract treatment group. Conclusion : SJS is potentially capable of limiting pancreatic damage during AP by restoring the fine structure of acinar cells and tissue; therefore, we conclude that SJS may have beneficial effects in the treatment of caerulein-induced AP.

This study was conducted to investigate the anti-inflammatory effects of Pruns mume, Schisandra chinensis, Chaenomeles sinensis-- Prunus mume mixtrue (PM) treatment on colitis induced in mice by dextran sodium sulfate (DSS) treatment. A total of 25 male BALB/c mice (average weight $20.7\;{\pm}\; 1.6 \;g$) were divided into 5 treatment groups and fed a commercial diet (A), PM administration (B), commercial diet + induced colitis by DSS (C), PM administration + induced colitis by DSS (D) and sulfasalazine + induced colitis by DSS (E). We found that PM treatment (D) and sulfasalazine (E) decreased the expression of $TNF-{\alpha}$ and COX-2 compared to the DSS-induced colitis group (C). The expression of IL-4, STAT6, $IFN-{\gamma}$, STAT1 was decreased in group D and group E compared to the colitis group (C), COX-2 and STAT1 were more decreased in group D. The serum IgE levels decreased in the PM treatment groups (C and D) compared to the non-PM treatment groups (A and B) although there was no significant difference between the PM treatment groups. It is notable that a therapeutic application of the PM extracts ameliorated DSS-induced colitis in mice.

To develop a new anti-inflammation agent for cosmetics, we investigated the anti-inflammatory activity of Fallopia sachalinensis RonseDecr. fruit extracts (FSR). FSR inhibited the pre-inflammatory cytokines ($1L-1{\beta}$, IL-6, TNF-${\alpha}$) and reduced NO production of RAW 264.7 macrophage cells in a dose-dependent manner and decreased the activity to about 51% at a concentration of $100{\mu}g/mL$. FSR suppressed not only the mRNA expression of iNOS and COX-2, but also the protein expression of iNOS and COX-2 in macrophage. The results suggested that FSR has considerable potential as a cosmetics ingredient with an anti-inflammatory effect.

PRF001 is a fragmented DNA polymer extracted from the testes of salmon. The purpose of this study was to assess the anti-inflammatory effect of PRF001 in vitro as well as the protective effect of PRF001 intake against arthritis in a rat model. In vitro, cell survival and inflammatory markers after $H_2O_2$ treatment to induce cell damage were investigated in CHON-001 cells treated with different concentrations of PRF001. In vivo, osteoarthritis was induced by intra-articular injection of monosodium iodoacetate (MIA) into the knee joints of rats. After consumption of PRF001 (10, 50, or 100 mg/kg) for 4 weeks, inflammatory mediators and cytokines in articular cartilage were investigated. In vitro, the levels of inflammatory markers, $IL-1{\beta}$, $TNF-{\alpha}$, COX-2, iNOS, and PGE2, were significantly suppressed by PRF001 treatment. In vivo, the inflammatory mediators and cytokines, $IL-1{\beta}$, p-Erk1/2, $NF-{\kappa}B$, $TNF-{\alpha}$, COX-2, and PGE2, as well as MMP3 and MMP7, which have catabolic activity in chondrocytes, were decreased in the MIA-induced osteoarthritic rats following intake of PRF001. Histological analysis revealed that PRF001 had a protective effect on the articular cartilage. Altogether, these results demonstrated that the anti-inflammatory property of PRF001 contributes to its protective effects in osteoarthritis through deregulating $IL-1{\beta}$, $TNF-{\alpha}$, and subsequent signals, such as p-Erk1/2, $NF-{\kappa}B$, COX-2, PGE2, and MMPs.

This study was performed to evaluate anti-thrombotic activities and anti-inflammatory effects of ChungyeolHaedogHwaeoTang water extract(CHHT). The results were summarized as follows. In experiment of anti-thrombotic effect; 1. CHHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group, and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 37.5%). 2. CHHT increased platelet number significantly, and also CHHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; 3. CHHT inhibited $IL-1{\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent degree as compared with the control of group in RAW 264.7 cell line. 4. CHHT inhibited $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production in spleen tissue, and also decreased $IL-1{\beta}$, and IL-6 production in liver tissue, but increased TNF-${\alpha}$ production in liver tissue of acute inflammation-induced Balb/c mice. 5. CHHT increased survival rate from the 3rd day in ICR mice with lethal endotoxemia induced by LPS. These results suggest that CHHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as menstrual pain, menstrual disorder, leukorrhea, vaginitis, cervicitis, pelvic inflammatory disease and so on.

Anti-inflammatory effects of sulfur-fed duck extract on colitis induced by 2.5% dextran sulfate sodium (DSS) were examined in male Balb/c mice. Animals were divided into eight groups: normal (0.1 mL of PBS without 2.5% DSS), control (0.1 mL of PBS with 2.5% DSS), SD-H (3 mL/kg of high sulfur-fed duck extract), SD-L (1 mL/kg of low sulfur-fed duck extract), GD-H (3 mL/kg of high general duck extract), GD-L (1 mL/kg of low general duck extract), GC-H (3 mL/kg of high general chicken extract), and GC-L (1 mL/kg of low general chicken extract). Mice were fed PBS or six different doses of extracts (sulfur-fed duck, general duck, and chicken), once daily for 14 days. Colitis was induced from day 7 to 14 via the administration of 2.5% DSS in drinking water. The colon length was significantly shortened in mice compared to the control group. The administration of SD-H, SD-L, and GD-L increased colon length and decreased histological colon injury from DSS-induced colitis. However, chicken extracts did not recover any clinical sign of the colitis. SD-L significantly suppressed not only the concentrations of IL-$1{\beta}$, IL-6, TNF-${\alpha}$, IL-17A, and IL-12 in serum but also the mRNA expressions of IL-6, TNF-${\alpha}$, iNOS and COX-2 in DSS-treated colon tissues (P<0.05). The administration of SD-H suppressed the concentrations of IL-6 in serum and the mRNA expressions of IL-6, iNOS, and COX-2 in colon tissues. Administration of GD-L suppressed the concentrations of IL-6, TNF-${\alpha}$, and IL-17A in serum and the mRNA expressions of IL-6, iNOS, and COX-2 in colon tissues. The inhibitory effects of sulfur-fed duck extracts were effective at a dose of 1 mL/kg. Our results indicate that sulfur-fed duck extracts may possess anti-inflammatory effects on DSS-induced colitis mice.

In this study, four compounds isolated from the red alga Laurencia snackeyi were evaluated for their potential anti-inflammatory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. These compounds were tested for their inhibitory effects on nitric oxide (NO) production in LPS-stimulated RAW 264.7 cells. Since $5{\beta}$-hydroxypalisadin B showed the best activity it was further tested for the production of prostaglandin-$E_2$ ($PGE_2$), expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), the release of pro-inflammatory cytokines tumor necrotic factor-alpha (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and interleukin-6 (IL-6). $5{\beta}$-Hydroxypalisadin B significantly reduced the $PGE_2$ release and suppressed the iNOS and COX-2 expression in LPS-stimulated RAW 264.7 cells. It also significantly reduced the release of pro-inflammatory cytokines TNF-${\alpha}$, IL-$1{\beta}$, and IL-6. These findings provide the first evidence of anti-inflammatory potential of $5{\beta}$-hydroxypalisadin B isolated from the red alga L. snackeyi and hence, it could be exploited as an active ingredient in pharmaceutical, nutraceutical and functional food applications.

BACKGROUND/OBJECTIVES: One of the mechanisms considered to be prevalent in the development of Alzheimer's disease (AD) is hyper-stimulation of microglia. Black chokeberry (Aronia melanocapa L.) is widely used to treat diabetes and atherosclerosis, and is known to exert anti-oxidant and anti-inflammatory effects; however, its neuroprotective effects have not been elucidated thus far. MATERIALS/METHODS: We undertook to assess the anti-inflammatory effect of the ethanolic extract of black chokeberry friut (BCE) in BV2 cells, and evaluate its neuroprotective effect in the lipopolysaccharide (LPS)-induced mouse model of AD. RESULTS: Following stimulation of BV2 cells by LPS, exposure to BCE significantly reduced the generation of nitric oxide as well as mRNA levels of numerous inflammatory factors such as inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), interleukin 1 beta ($IL-1{\beta}$), and tumor necrosis factor alpha ($TNF-{\alpha}$). In addition, AD was induced in a mouse model by intraperitoneal injection of LPS ($250{\mu}g/kg$), subsequent to which we investigated the neuroprotective effects of BCE (50 mg/kg) on brain damage. We observed that BCE significantly reduced tissue damage in the hippocampus by downregulating iNOS, COX-2, and $TNF-{\alpha}$ levels. We further identified the quinic acids in BCE using liquid chromatography-mass spectrometry (LCMS). Furthermore, we confirmed the neuroprotective effect of BCE and quinic acid on amyloid beta-induced cell death in rat hippocampal primary neurons. CONCLUSIONS: Our findings suggest that black chokeberry has protective effects against the development of AD.

It was examined that the effect of fermented traditional wine made by using mycelium of Phellinus linteus on the expression of inflammation-related proteins in HepG2 cells. HepG2 cells were incubated with or without ertract of traditional wine (ETMP), then analyzed by microscopic observation, reverse transcription polymerase chain reaction (RT-PCR) and Western blot. The results of RT-PCR and Western blot analyses showed that the level of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and tumor necrosis factor $(TNF)-{\alpha}$ was induced by LPS, Dut the treatment of ETMP inhibited the expression of these proteins and its mRNAs. Besides, the results of Western blot analyses showed that the expression of nuclear $factor-{\kappa}Bp65$ and $inhibitory-{\kappa}B{\alpha}$ were also slightly affected by ETMP treatment. These results suggest that ETM P alleviate the expression of inflammation-related protein expressions and thus may be used as a functional alcoholic beverage.
