Typha orientalis' stem (TOS) is traditionally used as an herbal medicine for difficulty in urination, galactophoritis purulenta, whooping cough, and allergic dermatitis. However, its effect in experimental models remains unknown. Here, we report the effect of TOS on the phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-induced inflammatory cytokine production and extracellular signal-regulated kinase (ERK) activation in the human mast cell line, HMC-1. TOS inhibited PMA plus A23187-induced cytokines such as tumor necrosis factor-alpha (TNF-$\alpha$) and interleukin (IL)-6. Maximal inhibition rate of TNF-$\alpha$ and IL-6 production by TOS (1 mg/ml) was about 44.02%, and 45.20%, respectively (P < 0.05). In addition, TOS inhibited the expression of TNF-$\alpha$ and IL-6 mRNA under the same condition. Moreover, TOS partially blocked PMA plus A23187-induced ERK phosphorylation. These results suggested TOS could inhibit the cytokine production through blocking of ERK activity.

In this study, we aimed to investigate the effect of GamiChungYi-tang(GCY-t) on caerulein-induced acute pancreatitis (AP). It is performed by detecting oxidative stress markers and observing histopathological examination. Thirty adult male rats(Sprague-Dawley) were divided into six groups as follows: normal (NOR,n=5), caerulein-induced (CON,n=5), caerulein+Cefotaxime Sodium(CT,n=5), caerulein+GCY-t (130 mg/kg, CHA,n=5), caerulein+GCY-t (260 mg/kg, CHB,n=5) and caerulein+GCY-t (520 mg/kg, CHC,n=5) groups. Pancreatic tissues of rats from all groups were removed for apoptosis and light, and electron microscopic examination. Blood of rats from all groups were collected for oxidative stress markers inspection and pathological examination. Pancreatic oxidative stress markers were evaluated by the measurements of leukocyte, serum amylase and platelet activating factor (PAF), Interleukin-6 (IL-6) levels were determined spectrophotometrically. CON group has a significant increase (p<0.05) in amylase compared with NOR, but CT and CHA, CHB, CHC groups reduced the levels of these enzyme. The levels of Platelet activating factor (PAF) were increased in CON compared with NOR, but decreased in CT and CHA, CHB, CHC groups compared with CON. Interleukin-6 (IL-6) levels were increased significantly in CON compared with NOR, but reduced in CT and CHA, CHB, CHC groups. In the observations of Optical microscopy and electron microscopy, The experimental groups showed the significant decreases in pancreatic tissue inflammation, edema, vacuolization, necrosis compared to the control group. After all, GCY-t is potentially capable of limiting pancreatic damage produced during AP by restoring the fine structure of acinar cells and tissue.

BACKGROUND/OBJECTIVES: Excessive intake of simple sugars induces obesity and increases the risk of inflammation. Thus, interest in alternative sweeteners as a sugar substitute is increasing. The purpose of this study was to determine the effect of saccharin on inflammation in 3T3-L1 adipocytes. MATERIALS/METHODS: 3T3-L1 preadipocytes were differentiated into adipocytes. The adipocytes were treated with saccharin (0, 50, 100, and 200 ㎍/mL) for 24 h. Inflammation was induced by exposure of treated adipocytes to lipopolysaccharide (LPS) for 18 h and cell proliferation was measured. The concentration of nitric oxide (NO) was measured by using Griess reagent. Protein expressions of nuclear factor kappa B (NF-κB) and inhibitor κB (IκB) were determined by western blot analysis. The mRNA expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin 1β (IL-1β), interleukin 6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and tumor necrosis factor-α (TNF-α) were determined by real-time PCR. RESULTS: Compared with the control group, the amount of NO and the mRNA expression of iNOS in the LPS-treated group were increased by about 17.6% and 46.9%, respectively, (P < 0.05), and those parameter levels were significantly decreased by saccharin treatment (P < 0.05). Protein expression of NF-κB was decreased and that of IκB was increased by saccharin treatment (P < 0.05). Saccharin decreased the mRNA expression of COX-2 and the inflammation cytokines (IL-1β, IL-6, MCP-1, and TNF-α) (P < 0.05). CONCLUSIONS: The results of this study suggest that saccharin can inhibit LPS-induced inflammatory responses in 3T3-L1 adipocytes via the NF-κB pathway.

The purpose of this study is to investigate effects of White Ginseng-Ejung-tang water extract (EJ) on production of various cytokines such as interleukin (IL)-2, IL-5, IL-6, IL-10, IL-12p70, macrophage inflammatory protein (MIP)-2, vascular endothelial growth factor (VEGF), keratinocyte-derived chemokine(KC), tumor necrosis factor (TNF)-${\alpha}$, and granulocyte macrophage colony-stimulating factor (GM-CSF) in RAW 264.7 mouse macrophages stimulated by lipopolysaccharide (LPS). Levels of cytokines were measured by High-throughput multiplex bead array cytokine assay based on xMAP (multi-analyte profiling beads) technology. EJ significantly decreased levels of IL-2, IL-12p70, IL-5, MIP-2 for 24 h incubation at the concentrations of 25, 50, and 100 ${\mu}g/mL$ in LPS-induced RAW 264.7 (P < 0.05). EJ significantly decreased levels of IL-6 at the concentrations of 50 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of IL-10 and VEGF at the concentrations of 25 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of KC at the concentrations of 100 ${\mu}g/mL$ (P < 0.05). EJ did not show any significant effect on TNF-${\alpha}$ and GM-CSF production. These results suggest that EJ has anti-inflammtory property related with its inhibition of IL-2, IL-5, IL-6, IL-10, IL-12p70, MIP-2, VEGF, and KC production in LPS-induced macrophages.

Background: Histone acetylation in chromatin structures plays a key role in regulation of gene transcription and is strictly controlled by histone acetyltransferase (HAT) and deacetylase (HDAC) activities. HDAC deregulation has been reported in several cancers. Materials and Methods: The expression of 10 HDACs (including HDAC class I and II) was studied by quantitative reverse transcription-PCR (qRT-PCR) in a cohort of mesenchymal stem cells (MM-MSCs) from 10 multiple myeloma patients with a median age 60y. The results were compared with those obtained for normal donors. Then, a coculture system was performed between MM-MSCs and u266 cell line, in the presence or absence of sodium butyrate (NaBT), to understand the effects of HDAC inhibitors (HDACi) in MM-MSCs on multiple myeloma cases. Also, the interleukin-6 (IL-6) and vascular endothelial growth factor (VEGFA) gene expression level and apoptotic effects were investigated in MM-MSCs patients and control group following NaBT treatment. Results: The results indicated that upregulated (HDACs) and downregulated (IL6 and VEGFA) genes were differentially expressed in the MM-MSCs derived from patients with multiple myeloma and ND-MSCs from normal donors. Comparison of the MM-MSCs and ND-MSCs also showed distinct HDACs expression patterns. For the first time to our knowledge, a significant increase of apoptosis was observed in coculture with MM-MSCs treated with NaBT. Conclusions: The obtained findings elucidate a complex set of actions in MSCs in response to HDAC inhibitors, which may be responsible for anticancer effects. Also, the data support the idea that MSCs are new therapeutic targets as a potential effective strategy for MM.

Objectives: Hwangryunhaedok-tang (HRHDT), a prescription composed of four herbs, has been wi dely used in Oriental Medicine for the treatment of cerebral infarction. However, the mechanisms by which the herbal formula affects on the production of pro- and anti-inflammatory cytokines in cerebral infarction patients remain unknown yet. Methods: The levels of pro- and anti-inflammatory cytokines, including tumor necrosis factor (TNF)-a, interleukin (IL)-1b, and IL-6, IL-10, and TGF-${\beta}1$ were determined in peripheral blood mononuclear cells (PBMCs) from cerebral infarction patients under our experimental conditions. Results: The secretory levels of pro- and anti-inflammatory cytokines, including tumor necrosis factor (TNF)-a, interleukin (IL)-1b, and IL-6, and IL-10 were significantly increased in phytohemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMCs) from cerebral infarction patients. However, pretreatment with HRHDT significantly inhibited the secretion of pro- and anti-inflammatory in PBMCs. Also, HRHDT induced a significant increase of transforming growth factor (TGF)-b1 in PBMCs. Conclusions: These data indicate that HRHDT may be beneficial in the suppression of inflammatory processes of cerebral infarct through suppression of TNF-$\alpha$, IL-$1{\beta}$, IL-6, and IL-10 and induction of TGF-${\beta}1$.

Omega-3, a polyunsaturated fatty acid, is an essential fatty acid necessary for human health, and it protects against cardiovascular disease, inflammation, autoimmune diseases, and cancer. In the present study, we investigated the effects of omega-3-rich harp seal oil (HSO) on the production of nitric oxide (NO) and cytokines, such as tumor necrosis factor (TNF)-${\alpha}$, interleukin-(IL)-$1{\beta}$, IL-6, and IL-12/IL-23 (p40) in peritoneal macrophages of mice. The culture supernatants of murine macrophages exposed to lipopolysaccharide (LPS), HSO, or HSO+LPS were harvested to assay IL-$1{\beta}$, TNF-${\alpha}$, IL-6, and IL-12/IL-23 (p40) cytokines and NO. TNF-${\alpha}$, IL-$1{\beta}$, and IL-12/IL-23 (p40) levels, except IL-6, were lower in the culture supernatants of mouse peritoneal macrophages exposed to LPS plus HSO than those of the groups exposed to LPS alone. These observations demonstrate that omega-3-rich harp seal oil downregulates the production of the pro-inflammatory cytokines such as IL-$1{\beta}$, TNF-${\alpha}$, and IL-12/IL-23 (p40). These results suggest that HSO could be potentially used as a preventive agent or as an adjunct in anti-inflammatory therapy, if more research results were accumulated.

Objectives : Scrophulariae Radix (SRE) is commonly used in combination with other herbs as a nutrient and health strengthening agent, and to remove 'heat' and replenish vital essence. The water-based extract of this herb can lower blood pressure in both anesthetized and concious animals, and exhibits an anti-inflammatory activity. But, there is lack of studies regarding the effects of SRE on the immunological activities in molecular levels. The present study was conducted to evaluate the effect of SRE on the regulatory mechanism of cytokines and nitric oxide (NO) in Raw 264.7 cells. Method : After the treatment of Scrophulariae Radix methanol extract, cell viability was measured by MTT assay, NO production was monitored by measuring the nitrite content in culture medium. COX-2 and iNOS were determined by Immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. Results : Results provided evidence that SRE inhibited the production of nitrite and nitrate (NO), inducible nitric oxide synthase (iNOS), $interleukin-1{\beta}\;(IL-1{\beta})$ and interleukin-6 (IL-6), and the activation of phospholylation of inhibitor ${\kappa}B{\alpha}\;(p-I{\kappa}B{\alpha})$ in Raw 264.7 cells activated with lipopolysaccharide (LPS). Conclusion : These findings suggest that Scrophulariae Radix can produce anti-inflammatory effect, which may playa role in adjunctive therapy in Gram-negative bacterial infections.

Objectives : Brain inflammation early activates the microglia and activated microglia secrete a variety of pro-inflammatory cytokines. Kaempferol, which is a flavonoid in Cuscutae Semen, shows a wide range of physiological activities, including neurons protection and anti-inflammatory actions through inhibition of pro-inflammatory mediators. The present study examined the modulatory effect of kaempferol on cytokines [tumor necrosis factor- alpha ($TNF-{\alpha}$), interleukin-1beta ($IL-1{\beta}$) and interleukin-6 (IL-6)] and cyclooxygenase-2 (COX-2) mRNA expression and microglia activation in the brain tissue of the mouse. Methods : Kaempferol was administered orally three doses of 10, 20 and 30 mg/kg respectively, once 1 hour before the lippolysaccharide(LPS) (3 mg/kg, i.p.) injection. Brain tissue was removed at 4 hours after LPS injection. Cytokines and COX-2 mRNA expression in the brain tissue was measured by the quantitative real-time polymerase chain reaction (PCR) method. Iba1 expression was calculated by western blotting method. Microglia was observed with immunohistochemistry. Immunohistochemistry stained microglia was analyzed by using ImageJ software. Results : Kaempferol 20 and 30 mg/kg was significantly attenuated the expression of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 mRNA. Kaempfrol 10, 20 and 30 mg/kg significantly attenuated COX-2 mRNA expression in the brain tissue. Kaempferol 30 mg/kg significantly suppressed the increase of Iba1 protein expression by LPS. Kaempferol 30 mg/kg significantly decreased the number of microglia in the cerebral cortex and the number and cell size of microglia in the hypothalamic region and the area percentage of ionized calcium binding adaptor molecule 1(Iba1)-expressed microglia in the hippocampus. Conclusions : This results indicate that kaempferol plays an anti-inflammatory role in the brain.
