  • We previously reported that DA-9601, ethanol herbal extract of Artemisia asiatica, inhibited histamine and leukotriene releases in guinea pig lung mast cells activated with specific antigen/antibody reaction. This study aimed to evaluate the inhibitory effect of DA-9601 on the OVA-induced airway inflammation in allergic asthma mouse model. BALB/c mice were sensitized and challenged with OVA. DA-9601 was administered orally 1 h before every local OVA-challenge. OVA-specific serum IgE was measured by ELISA, recruitment of inflammatory cells in BAL fluids and lung tissues by Diff-Quik and H&E staining, respectively, the expressions of CD40, CD40L and VCAM-1 by immunohistochemistry, goblet cell hyperplasia by PAS staining, activities of MMPs by gelatin zymography, expressions of mRNA and proteins of cytokines by RT-PCR and ELISA, activities of MAP kinases by western blot, and activity of NF-${\kappa}B$ by EMSA. DA-9601 reduced IgE level, recruitment of inflammatory cells into the BAL fluid and lung tissues, expressions of CD40, CD40L and VCAM-1 molecules, goblet cell hyperplasia, MMPs activity, expressions of mRNA and productions of various cytokines, activities of MAP kinases and NK-${\kappa}B$ increased from OVA-challenged mice. These data suggest that DA-9601 may be developed as a clinical therapeutic agent in allergic diseases due to suppressing the airway allergic inflammation via regulation of various cellular molecules expressed by MAP kinases/NF-${\kappa}B$ pathway.

  • The effects of MeOH extracts of Schizandra chinensis fructus (SZX) on the immunoregulatory effect (lymphocyte proliferation, subpopulation, nitric oxide production, phagocytic activity) and apoptosis $(sub-G_1\;peak)$ of L1210 cells were examined. The proliferation of splenocytes and thymocytes were enhanced by the addition of $10\;{\mu}g/mL$ of SZX. SZX were administered p.o. once a day for 7 days in adult male BALB/c mice. SZX resulted in altering subpopulation of splenic B and/or T and thymic T lymphocytes, especially the number of $T_H$ cells were markedly increased by the treatment of SZX in vivo and in vitro. SZX treatment induced the apoptotic cell death in L1210 mouse leukemia cells. In addition, SZX accelerated the production of nitric oxide and phagocytic activity in peritoneal macrophages. These results suggest that SZX have an immunoregulatory property and anti-cancer action.

  • Objectives This study investigated the effects of Cheongyeonsan for allergic rhinitis. Methods First, the GS/MS was used to analyze the effects of Cheongyeonsan by measuring inflammatory markers. Second, 3 groups of 10 6-week-old BALB/c mice were divided into Ctrl (no treatment), ARE (allergic rhinitis-induced without treatment), and CRT (allergic rhinitis-induced after Cheongyeonsan treatment) groups. Ovalbumin (OVA) was used as an antigen to induce allergic rhinitis and sensitization was performed by intraperitoneal injection of 0.1% OVA solution 21, 14, and 7 days before the onset of allergic rhinitis. Allergic rhinitis was induced by dropping OVA solution on the nasal cavity of each mouse for 5 days after the last sensitization. Seven days after the first induction, second induction was introduced by the same method. After making the section, MMP-9, substance P, $TNF-{\alpha}$, $NF-{\kappa}B$ p65, COX-2, iNOS and Nrf, apoptotic cells were observed by Masson trichrome staining, immunohistochemical staining, TUNEL of nasal mucosal tissues of each group. Results GC/MS results showed undecanoic acid. Masson trichrome results showed that the CRT group had less respiratory epithelial damage. Immunohistochemical staining showed CRT group had 58% decrease in MMP-9, 61% decrease in substance P, 55% decrease in $TNF-{\alpha}$, 38% decrease in $NF-{\kappa}B$ p65, 53% decrease in COX-2, 54% decrease in iNOS, 87% increase in Nrf compared to those of the ARE group. TUNEL showed a positive reaction of 84% increase in apoptotic cells greater than that of the ARE group. Conclusions Cheongyeonsan alleviates nasal mucosal damage and reduces inflammatory mediators from allergic rhinitis-induced mice.

  • Molecular cloning of gene for $\alpha$-acylamino-$\beta$-lactam acylhydrolase (ALAH) III from Acetobacter turbidans has been attempted by immunochemical detection method, in which polyclonal antibody from mouse Balb/c against this enzyme was employed as a probe. As a cloning vector, λ gtll was chosen for this purpose. Two positive clones has been selected from genomic libraries of A. turbidans, which had somewhat different binding affinities on anti-ALAH III umm and anti-$\beta$-galactosidase. By restriction analysis, both clones has been turned out to lose one of EeoRI sites. From these results, it concluded that deletion of DNA between lacZ gene and inserted DNA has occurred during replication of these clones in host cells.

  • The emergence of antibiotic-resistant bacterial strains is one of the most critical problems of modern medicine. Bacteriophages have been suggested as an alternative therapeutic agent for such bacterial infections. In the present study, we examined the therapeutic potential of phage Kpn5 in the treatment of Klebsiella pneumoniae B5055-induced burn wound infection in a mouse model. An experimental model of contact burn wound infection was established in mice employing K. pneumoniae B5055 to assess the efficacy of phage Kpn5 in vivo. Survival and stability of phage Kpn5 were evaluated in mice and the maximum phage count in various organs was obtained at 6 h and persisted until 36 h. The Kpn5 phage was found to be effective in the treatment of Klebsiella-induced burn wound infection in mice when phage was administered immediately after bacterial challange. Even when treatment was delayed up to 18 h post infection, when all animals were moribund, approximately 26.66% of the mice could be rescued by a single injection of this phage preparation. The ability of this phage to protect bacteremic mice was demonstrated to be due to the functional capabilities of the phage and not due to a nonspecific immune effect. The levels of pro-inflammatory cytokines (IL-$1{\beta}$ and TNF-${\alpha}$) and anti-inflammatory cytokines (IL-10) were significantly lower in sera and lungs of phage-treated mice than phage untreated control mice. The results of the present study bring out the potential of bacteriophage therapy as an alternate preventive approach to treat K. pneumoniae B5055-induced burn wound infections. This approach not only helps in the clearance of bacteria from the host but also protects against the ensuing inflammatory damage due to the exaggerated response seen in any infectious process.

  • In order to investigate the inhibitory effects on the type IV allergy reaction of the hot water extracts (10 mg/20 g body weight) from medicinal herbs (Flos magnoliae, Poncirus trifoliata, Bupleurum falcatum, Scutellaria baicalensis, Schisandra chinensis), delayed type hypersensitivity by 2,4-dinitro-1-fluorobenzene (DNFB) was measured. Scutellaria baicalensis, Schisandra chinensis and Poncirus trifoliata showed inhibitory effects on the delayed type hypersensitivity by DNFB in the 1'st and 2'nd sensitized mice, but Flos magnoliae showed valuable changes only in the 2'nd sensitized mice. Inhibitory effect of Bupleurum falcatum had no statistical significance (p>0.05). According to above results, Scutellaria baicalensis, Schisandra chinensis and Poncirus trifoliata are supposed to be effective as anti-delayed type allergic regimen.

  • Numerous studies have suggested that Korean red ginseng (KRG) extract has various immune modulatory activities both in vivo and in vitro. In this study, we used a mouse model to examine the effects of orally administered KRG extract on immunity against herpes simplex virus (HSV). Balb/c mice were administered with 100, 200, and 400 mg/kg oral doses of KRG extract for 10 d and then vaginally infected with HSV. We found that KRG extract rendered recipients more resistant against HSV vaginal infection and further systemic infection, including decreased clinical severity, increased survival rate, and accelerated viral clearance. Such results appeared to be mediated by increased vaginal IFN-${\gamma}$ secretion. Moreover, increased mRNA expression of IFN-${\gamma}$, granzyme B, and Fas-ligand was identified in the iliac lymph node and vaginal tracts of KRG extract treated groups (200 and 400 mg/kg). These results suggest that the activities of local natural killer cells were promoted by KRG extract consumption and that KRG may be an attractive immune stimulator for helping hosts overcome HSV infection.

  • Korean red ginseng (KRG) is reported to have anti-allergic properties, including beneficial effects on asthma and atopic dermatitis. However, its effect on allergic rhinitis has not been studied extensively. This study examined how KRG affected allergic inflammation of the nasal cavity in an allergic mouse model. A total of 40 Balb/c female mice were divided into four experimental groups according to treatment and allergic state: group 1 (G1), saline only; group 2 (G2), ovalbumin (OVA); group 3 (G3), OVA+KRG; and group 4 (G4), OVA+dexamethasone. Serum IgE levels were significantly lower in the KRG treatment group (G3) than in the allergic group (G2). However, serum IgG1 levels did not differ between G2 and G3. In the nasal lavage fluid, IL-4 and IL-5 levels were significantly lower in G3 than in G2 (p<0.05). H&E and Luna staining revealed that the eosinophil count was lower in G3 and G4 than in G2 (p<0.05). Immunohistochemical staining revealed that there were fewer IL-4-, IL-5-, and MUC5AC-positive cells in G3 and G4 than in G2 (p<0.05). These results indicate that KRG reduces the nasal allergic inflammatory reaction in an allergic murine model by reducing Th2 cytokines.
