Objective: To research the trends of study related to rhinitis and acupuncture in PubMed, and to establish the hereafter direction of treating rhinitis with acupuncture Methods: We searched PubMed and chinese medical journals related to rhinitis and acupuncture. Results: 1. The pattern of the study was as follows: Review article(3), Randomized controlled trials(2), Clinical trial(11), Case report(12). 2. The effect of acupuncture on rhinitis is reported as follows: Acupucture treatment improves the scale of symptoms, nasal airways resistance and velocity of the mucociliary transport, decreasing absolute numbers of blood eosinophils, serum IgE and percentage of nasal eosinophils. Immunologically acupuncture treatment could reduce plasma IL-10 level, control IL-2, and balance between cell-specific pro-inflammatory and anti-inflammatory cytokines, TNF-${\alpha}$ and IL-10. After acupuncture treatment, there is statistically significant changes in IgA, IgE, E-rosette formative rate. 3. Many of these article have affirmative view for therapeutic effect of rhinitis with acupuncture. Statistical test was done only in 6 papers. There showed statically significant results in 4 articles, and in 2 article there showed some clinical improvement but no statically significant changes. 4. In Western countries, alternative treatments are frequent among adults with rhinitis or other allergic disease, and affirmative tendency for acupuncture treatment is increased.

Imperatorin has been known to exert many biological functions including anti-inflammatory activity. In this study, we investigated the inhibitory effects of imperatorin on the production of inflammatory mediators in mouse bone marrow-derived mast cells (BMMC). Imperatorin inhibited degranulation and the generation of eicosanoids (leukotriene $C_4$ ($LTC_4$) and prostaglandin $D_2$ ($PGD_2$) in IgE/antigen (Ag)-stimulated BMMC. To elucidate the molecular mechanism involved in this process, we investigated the effect of imperatorin on intracellular signaling in BMMC. Biochemical analyses of the IgE/Ag-mediated signaling pathway demonstrated that imperatorin dramatically attenuated degranulation and the production of 5-lipoxygenase-dependent $LTC_4$ and cyclooxygenase-2-dependent $PGD_2$ through the inhibition of intracellular calcium influx/phospholipase $C{\gamma}1$, cytosolic phospholipase $A_2$/mitogen-activated protein kinases and/or nuclear factor-${\kappa}B$ pathways in BMMC. These results suggest that the effects of imperatorin on inhibition of degranulation and eicosanoid generation through the suppression of multiple steps of IgE/Ag-mediated signaling pathways would be beneficial for the prevention of allergic inflammation.

In this study, the inhibitory activities of fifty plant extracts on IgE-mediated degranulation in the rat basophilic leukemia cell line (RBL-2H3 cells) were measured; the release of interleukin (IL)-4 and β-hexosaminidase from IgE-sensitized cells treated with the plant extracts was measured; and the effects of the plant extracts on cell viability were tested. The results of the analysis of plant extracts at 20 μg/ml, including the aerial part of Magnolia sieboldii K. Koch, exhibited suppressive activities upon the release of IL-4. Furthermore, several plant extracts including methanol extracted from Lindera erythrocarpa Makino (aerial part) at the same concentration significantly inhibited the release of β-hexosaminidase. Twenty-six of the plant extracts, including methanol extract of Weigela subsessilis (Nakai) L. H. Bailey (branch), showed a cell proliferation effect of over 80% at 100 μg/ml. In conclusion, the results suggest that the leaf/stem of Geum japonicum Thunb. and the stamen/ovary of Nelumbo nucifera Gaertn., which exhibited effective inhibition on β-hexosaminidase release and IL-4 release from mast cells and showed high cell viability, could be useful candidates as anti-allergy materials.

Objectives In this study, we investigated the inhibitory effects of Samhwangsasim-tang (S.H) on the allergic response caused by ovalbumin(OVA) sensitization and challenge in BALB/c mice. Methods The experimental animals were divided into five groups; 1) normal as negative control, 2) OVA-sensitized mice, 3) OVA-sensitized mice treated with 200 mg/kg of S.H 200, 4) OVA-sensitized mice treated with 400 mg/kg of S.H 400, and 5) OVA-sensitized mice treated with 5 mg/kg of Dexamethasone (Dex). Antigen sensitization for allergic mouse model was performed with twice injection of OVA for 2 weeks. After secondary injection, S.H was administrated orally into mice every day for 13 days and the inhibitory effect of S.H on allergic responses was evaluated. Results Treatment of S.H into allergic mice reduced significantly ear edema and infiltration of immune cells in ear tissues induced with OVA challenge in a dose-dependent manner. S.H reduced significantly the serum levels of Total Immunoglobulin(Ig)G and IgE, and particularly inhibited the production of OVA-specific IgE, but not OVA-specific IgG. The serum level of proinflammatory cytokine TNF-${\alpha}$ and Th2-associated cytokine IL-4 also were significantly decreased by S.H adminstration in a dose denpendent manner. S.H attenuated OVA-induced secretion of IFN-${\gamma}$, but not IL-12 which is a cytokine inducing the development of Th1 cells. It also reduced significantly the secretion of IL-4, which is a cytokine inducing the development of Th2 cells, after splenocytes were stimulated with OVA. However the secretion of IL-5 and IL-13 was influenced weakly or a little. Conclusions These results indicate that S.H could reduce the allergic response through inhibition of antigen-specific IgE and Th2-inducing cytokines. It suggest that S.H may be available clinically for the treatment of allergic patients.

The antioxidant, whitening, and anti-wrinkle activity of Spirodela polyrhiza extracts and fractions were evaluated to determine its efficacy as a functional cosmetic material. 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activities were 44.2 and 74.3%, respectively, at 100 ㎍/mL of SE-E (the ethyl acetate fraction of 70% ethanol extract). To measure anti-wrinkle effects, procollagen biosynthesis and matrix metalloproteinase-1 (MMP-1) inhibition activity were determined. At 25 ㎍/mL of SE (70% ethanol extract), the biosynthesis activity was 48.5%, and SE-E showed the best activity (57.8%) at the same concentration. MMP-1 inhibition activity of SE and SE-E was 13.4 and 28.5%, respectively, at 25 ig/mL. Finally, the inhibition of cellular melanin synthesis and cellular tyrosinase were measured to determine the whitening effect; at 25 ㎍/mL, the inhibition activities of SE were 9.6 and 13.8%, respectively, and those for SE-E were 15.4 and 22.0%, respectively. Our results confirmed the possibility of SE and SE-E as effective functional materials. Further research investigating the antimicrobial, anti-inflammatory, and anticancer activities of S. polyrhiza is necessary to confirm its potential use in the food, cosmetics, and drug industries.

Sopung-san(SPS; prescription No. DO27), a herbal medicine prescribed by oriental hospital of Daegu fanny University, has been used as cure for pruritus and psoriasis. To evaluate anti-inflammatory effect of Sopung-san, we treated Sopung-san extract in animal model system induced contact hypersensitivity. Contact hypersensitivity, a local inflammatory response of the skin, was induced by 1% DNCB on the right ear of BALB/C mouse. Sopung-san was prepared as water extract and administrated everyday for 2 weeks per oral. A right ear of mouse was potently swelled by 1% of DNCB treatment, but a mouse ear thickness was significantly reduced by Sopung-san after 2 weeks. treatment. Sopung-san reduced IgG in serum obtained from blood of 1 % DNCB-treated mouse. IgE in serum was not changed by DNCB and/or Sopung-san treatment. $IL-1{\beta}$ and IL-6 from ear tissue were significantly increased by DNCB, Dut were not reduced by Sopung-san. From these results, anti-inflammatory effect of Sopung-san, especially reduction of ear swelling, might be partly due to reduction of IgG in serum.

Rumex crispus is known to have anticancer, antioxidant, antibacterial, and bone loss inhibitory activities. Mast cells are critical immune cells that induce a type 1 IgE-mediated allergic reaction. However, there are no reports of inhibitory effects of Rumex crispus on mast cells and allergic reactions. In this study, we performed some experiments to investigate whether Rumex crispus ethanol extract(RCE) has any inhibitory effect on antigen-induced type I allergic response in vitro and in vivo. RCE inhibited degranulation of IgE-mediated mast cells(IC₅₀, ~57 ㎍/ml) and cytokine production such as TNF-α and IL-4 in a dose-dependent manner. In vivo, RCE significantly inhibited passive cutaneous anaphylaxis(PCA)(ED₅₀, ~198 mg/kg) in mice. Furthermore, RCE inhibited degranulation of MCs in ear tissue of mice with PCA. Mechanism studies showed that RCE inhibited the activation of Syk and Syk-dependent pathway such as LAT, PLC-γ, Akt, and MAP Kinase. Our results demonstrate for the first time that RCE inhibits type I hypersensitive response by suppressing the activity of Syk in mast cells, thereby reducing degranulation and cytokine production. Taken together, RCE could be used as a novel therapeutic material to suppress allergic diseases.
