  • Objectives : Scutellaria barbata has been widely used in oriental medicine used for treatment of acute and chronic inflammatory diseases. In this study, to investigate the protective effect of Scutellaria barbata on type I allergic response, we determined whether Scutellaria barbata inhibits early or late allergic responses. Methods : To assess the effect of Scutellaria barbata Pharmacopuncture Extract(SB) in RBL-2H3 cells, we investigated the levels of the markers of degranulation such as ${\beta}$-hexosaminidase and histamine, inflammatory mediator such as IL-4, TNF-${\alpha}$, PGE2 and cysLT, and mRNA expression of cytokines and enzymes. In addition, we determined the levels of intracellular ROS by DCFH-DA assay and the free radical scavenging activity by DPPH method. Results : We found that SB suppressed the release of ${\beta}$-hexosaminidase and histamine and the production of IL-4, TNF-${\alpha}$, PGE2 and cysLT in RBL-2H3 by the antigen stimulation. SB also significantly inhibited the enzyme mRNA expressions, such as HDC2, COX-1, COX-2, 5-LOX and iNOS2, along with reduced cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ and GM-CSF in RBL-2H3. In addition, SB suppressed the levels of intracellular ROS. Conclusions : Our results indicate that SB protects against type I allergic response and exert an anti-inflammatory effect through the inhibition of degranulation, inflammatory mediator release and mRNA expression of cytokines and enzymes.

  • Vittorio Alfieri fu celebrato dagli uomini del Risorgimento come "l'iniziatore ed il padre della rinascita" e il creatore della coscienza nazionale. Per questo è lodato da Foscolo, Manzoni, Leopardi, Mazzini, Gioberti, Oriani, Carducci. Ma insieme con i suoi meriti politici, anche i valori artistici delle sue opere non debbono essere dimenticati. Anche sul pensiero e sull'opera dell'Alfieri influirono le ideologie tipiche del secondo Settecento, l'Illuminismo e il nascente Romanticismo, in lui intrecciandosi e scontrandosi ad un tempo. Il suo interesse per lo studio dell'uomo, per la concezione meccanicistica del mondo, la lontananza dalla religione per l'assoluta libertà e l'avversione verso il dispotismo, collegano Alfieri alla dottrina illuminista. I temi letterari illuministici, volti a chiarificare le coscienze e ad apportare il progresso sociale e civile, sono affrontati dal poeta non in modo distaccato, ma con l'emotività e le inquietudini del pensiero romantico. Ma i letterati romantici dell'Ottocento furono piuttosto ostili all'opera dell'Alfieri, accusandola di astratezza, di lontananza dagli interessi e dalla realtà della vita moderna e di assenza di senso storico. Invece nei primi anni del Novecento, Croce lo presenta come iniziatore della nuova letteratura italiana, con la quale egli avrebbe in comune l'individualismo, la passionalità, l'amore per la solitudine, la malinconia. Anche se gli manca l'ansia religiosa sul fine e il valore della vita e l'interessamento per la storia, ecc., secondo il Croce si può definire un protoromantico. Nelle sue opere ci sono, sotto l'aspetto dell'Illuminismo l'odio istintivo contro la tirannide e l'amore per la libertà, e sotto quello protoromantico esplode l'urto violento di sentimenti e passioni e l'esaltazione della morte eroica dei protagonisti. E anche Saul e Mirra descrivono l'idea dell'umanità eroica che muore dopo una lunga vicenda di miseria e di abbiezione. L'idea dell'umanità nuova in Saul e Mirra è l'idea degli uomini nuovi che egli desiderava.

  • Se siamo d'accordo la definizione di Deleuze e Guattari che la letteratura minore è la letteratura che costruisce una minoranza dentro la lingua maggiore, le scritture italofoniche sono la traduzione in pratica di un concetto della letteratura minore che fornisce modelli sostitutivi di espressione. Questa minoranza di bilingue, o più precisamente, multilingue autori e pratiche, acquisisce uno spazio dentro della cultura e la lingua italiana, che di conseguenza sono entrambi deterritorializzati. Lo stanziamento di italiano come lingua in cui sono scritti i testi italofonici richiede una pratica influenza linguistica e culturale. Questa ibridazione linguistica e letteraria riverbera la pluralità sociale presente nella moderna Italia, dove oltre un milione di immigrati provenienti da tutto il mondo vivono oggi. Questo collegamento tra il letterario e il sociale si diffonde il senso di deterritorializzazione linguistica per definire personificazioni di 'otherness', sia per i corpi degli immigrati stessi sia per la politica. I testi italofonici rapresentano contemporaneamente l'individuo e il collettivo, cioè, l'esperienza individuale e la vita delle comunità di immigrati.

  • The arterial pressure is regulated by the nervous and humoral mechanisms. The neuronal regulation is mostly carried out by the autonomic nervous system through the rostral ventrolateral medulla (RVLM), a key area for the cardiovascular regulation, and the humoral regulation is mediated by a number of substances, including the angiotensin (Ang) II and vasopressin. Recent studies suggest that central interleukin-1 (IL-1) activates the sympathetic nervous system and produces hypertension. The present study was undertaken to elucidate whether IL-1 and Ang II interact in the regulation of cardiovascular responses to the stress of hemorrhage. Thus, Sprague-Dawley rats were anesthetized and both femoral arteries were cannulated for direct measurement of arterial pressure and heart rate (HR) and for inducing hemorrhage. A guide cannula was placed into the lateral ventricle for injection of IL-1 $(0.1,\;1,\;10,\;20\;ng/2\;{\mu}l)$ or Ang II $(600\;ng/10\;{\mu}l)$. A glass microelectrode was inserted into the RVLM to record the single unit spike potential. Barosensitive neurons were identified by an increased number of single unit spikes in RVLM following intravenous injection of nitroprusside. I.c.v. $IL-1\;{\beta}$ increased mean arterial pressure (MAP) in a dose-dependent fashion, but HR in a dose-independent pattern. The baroreceptor reflex sensitivity was not affected by i.c.v. $IL-1\;{\beta}$. Both i.c.v. $IL-1\;{\alpha}\;and\;{\beta}$ produced similar increase in MAP and HR. When hemorrhage was induced after i.c.v. injection of $IL-1\;{\beta}$, the magnitude of MAP fall was not different from the control. The $IL-1\;{\beta}$ group showed a smaller decrease in HR and a lower spike potential count in RVLM than the control. MAP fall in response to hemorrhage after i.c.v. injection of Ang II was not different from the control. When both IL-1 and Ang II were simultaneously injected i.c.v., however, MAP fall was significantly smaller than the control, and HR was increased rather than decreased. These data suggest that IL-1, a defense immune mediator, manifests a hypertensive action in the central nervous system and attenuates the hypotensive response to hemorrhage by interaction with Ang II.

  • Scopoletin is a component of several plant such as Erycibe obtusifolia, Aster tataricus, Foeniculum vulgare and Brunfelsia grandiflora. It was reported to have anti-angiogenesis and anti-allergy effects. In this study, the anti-inflammatory effect of scopoletin was investigated in Raw264.7 cells, mouse macrophages. The effects of scopoletin on phagocytosis and nitric oxide (NO) production were investigated in lipopolysaccharide (LPS)-induced inflammatory responses. It was observed that scopoletin exerted inhibitory effects on both phagocytosis and NO production. In addition, scopoletin decreased the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) which were related to NO and prostaglandin E2 (PGE2) production. In particular, the expression of pro-inflammatory cytokines such as interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). The expression levels of IL-1β, IL-6 were remarkably decreased by treatment with scopoletin. Furthermore, the content of TNFα produced by macrophage was decreased in the presence of scopoletin at 8 hr. These results indicate that the anti-inflammatory effect of scopoletin could exert by inhibiting the expression of pro-inflammatory cytokines in Raw264.7 cells stimulated with LPS. The above results suggest scopoletin could be a new remedial agent for anti-inflammation through inhibition of iNOS, COX-2, IL-1β, IL-6 and TNF-α expressions as well as supression of phagocytosis and NO production.

  • The purpose of this study was to investigate the anti-inflammatory effects of extract from GuBoEum(GBE) on the peritoneal macrophage. To evaluate anti-inflammatory effects of GBE. I measured cytokines (interleukin-6; IL-6, interleukin-12; IL-12, tumor necrosis factor-$\alpha$; TNF-$\alpha$) and nitric oxide (NO) production in lipopolysacchride (LPS)-induced macrophages. Furthermore, I examined molecular mechanism using western blot and also LPS-induced endotoxin shock. Extract from GBE does not have any cytotoxic effect in the peritoneal macrophages. Extract from GBE reduced LPS-induced IL-6, TNF-$\alpha$, IL-12 and NO production in peritoneal macrophages. GBE inhibited the activation of extracelluar signal-regulated kinase (ERK), C-Jun $NH_2$-terminal kinase (JNK) but not of p38, degradation of $I{\kappa}B-{\alpha}$ in the LPS-stimulated peritoneal macrophages. GBE inhibited the production of TNF-$\alpha$, IL-6 and IL-12 in serum after LPS injection. These results suggest that GBE may inhibit the production of TNF-$\alpha$, IL-6, and IL-12 through inhibition of ERK and JNK activation, and that GBE may be beneficial oriental medicine for inflammatory diseases.

  • Objective : This study was performed to investigate the anti-fibrogenic effect and changes of inflammation-related genes by YBR I and YBR II (YBR I: Arteisiae Capillaris Herba, Atractylodis Rhizoma Alba, Hoelen/ YBR II: YBR I +Sanguisorbae Radix, Biotae Cacumen, Cirsii Japonici Herba) on HSC(hepatic stellate cells)-T6 and TAA-induced rat liver tissue. Materials and Methods : HSC-T6 were treated with various concentrations of distilled-water extract YBR I and YBR II extract for 24, 48 and 72 hours. After the treatment, cell viability, proliferation, procollagen levels and IL-6 levels were measured by using MTT Assay, BrdU Assay, Procollagen Type 1 C-peptide EIA kit, and Murine IL-6 ELISA Development kit. Rat liver fibrosis was induced by intraperitoneal TAA injection of 150mg/kg 3 times a week for 6 weeks. After the treatment, body weight, liver & spleen weights, liver function test, complete blood cell count and change of portal pressure were studied. In addition, gene expressions of ASMA, IL-6, MMP-2, TIMP-1 and TIMP-2, all of which are known to be associated with liver fibrosis, were analyzed by using Real-Time PCR. After YBR I and YBR IItreatment, percentages of collagen in TAA-induced rat liver tissue were measured. Results : The viability and proliferation of the HSC-T6 decreased as the concentration increased. The production of procollagen decreased as the concentration increased. The production of IL-6 was little influenced by YBR I and YBR II. There was no difference in rat body weight between the TAA-only group and the YBR groups. Compared with rat liver weight of TAA-only group, that of the YBR groups increased. In the YBR I group, the serum level of AST elevated by TAA injection significantly decreased and in the YBR I and II group, the serum level of ALP and ALT elevated by TAA injection decreased. In the YBR I group, white blood cell count elevated by TAA injection decreased but platelets increased. In the YBR I group, the portal pressure elevated by TAA injection significantly decreased. Decreases in the gene expression of ASMA and MMP-2 were observed in the YBR I group. The gene expression of IL-6 was little influenced by YBR I and YBR II -treated groups. In the histological finding, TAA injections caused severe fibrosis, but YBR I and YBR II treatment significantly reduced the amounts of hepatic collagens. Conclusions : These results suggest that YBR I and II have inhibitory effects on the hepatic fibrogenesis.

  • The present study was conducted to evaluate the regulation mechanism of nitric oxide(NO) by water-extracted Cyperus rotundus (WCR) in RAW 264.7 macrophages. We investigated the effects of cell proliferation in mouse spleen cell and RAW 264.7 macrophages cells. WCR enhanced mitogenic activity in the dose-response manner in mouse spleen cells and RAW 264.7 macrophages cells. In nitric oxide (NO) synthesis by WCR, WCR alone had an effect on NO synthesis. It was found that the production of NO of RAW 264.7 cells stimulated with lipopolysaccharide (LPS) could be markedly inhibited by WCR. Inhibition of NO production was achieved by reducing inducible nitric oxide syntheses(iNOS) mRNA expression. The expression of IL-I gene by WCR was investigated using reverse transcription polymerase chain reaction (RT-PCR). In RT-PCR, IL-1 family(IL-1 α, IL-1β) expressions were induced by WCR. These finding suggested that regulation of NO production by WCR may be, at least in part, associated with the regulation of iNOS mRNA expression and IL-1 family gene expression.

  • Eurya emarginata (Thunb.) Makino (Theaceae) is distributed in coastal areas of island. The leaves of Eurya are used in the traditional medicine of the coastal areas of jeju island with the aim of diuresis or to treat ulcers. Nevertheless, there are few reports on the biological activity and constituents of E. emarginata. In this study, we investigated the pharmacological activity of the solvent extracts of E. emarginata on the several inflammatory markers (TNF-$\alpha$, IL-1$\beta$, IL-6, NO, iNOS and COX-2). Also we examined the antioxidizing effect of the solvent extracts by determination of DPPH radical-scavenging activity. Among the solvent fractions, EtOAc and BuOH extracts showed potent radical scavenging activity (RC$_{50}$=10.9 and 12.7 respectively). The subtractions of EF 5-4-6-3-2 and BF 1 potentially inhibited the mRNA expression of pro-inflammatory cytokines (IL-1$\beta$, IL-6 and TNF-$\alpha$) at the concentration of 100 $\mu\textrm{g}$/mι. Also the fractions inhibited the mRNA expression of pro-inflammatory cytokines (IL-1$\beta$, IL-6 and TNF-$\alpha$) and protein expression of iNOS and COX-2 at the concentration of 100 $\mu\textrm{g}$/mι. And then, the inhibition of iNOS was correlated with the decrease of nitrite level. These results suggest that E. emarginata may have anti-inflammatory activity through the inhibition of pro-inflammatory cytokines, iNOS and COX-2.2.
