Purpose : To investigate the effects of the lavender, lemon and eucalyptus oil mixture on the atopy dermatitis skin lesions induced on NC/Nga Mice by dinitrochlorobenzene (DNCB). Material and Method : For this purpose, we fabricated the oil mixture blending three essential oils (lavender, lemon, eucalyptus : ELL) with one carrier oil (jojoba) and apply it on the atopic dermatitis skin lesions of NC/Nga Mice. Atopic dermatitis in NC/Nga Mice was induced by DNCB treatment on the dorsal skin of mice for 8 weeks. The mixture of ratio of each essential oil drop was 1 (eucalyptus) : 2 (lemon) : 2 (lavender) and this mixture was blended with jojoba oil 50ml (0.025%). The ELL-ointment was supplied for 8 weeks. We evaluated the effects of ELL on cell viability of mouse lung fibroblast, clinical skin features and severity, the level of serum Immunoglobulin (Ig) E & Ig G1, Interleukin (IL)-4, IL-13 and Interferon (IFN)-$\gamma$. Results : ELL showed safety on the cell viability of mouse lung fibroblast compared with control group. The cell viability was measured by SRB method. The effects of ELL on clinical skin features and severity in DNCB-induced dermatitis model of NC/Nga mice was significant compared with control group. EEL also showed significant effects on clinical symptom score compared with control group. Serum IgE & IgG1 level and development of atopy dermatitis skin lesions were evaluated. Serum IgE & IgG1 production was significantly down-regulated in EEL group compared with control group. ELL also down-regulated the levels of IL-4 and IL-13, and up-regulated the level of IFN-$\gamma$ compared with control group significantly. Conclusion : ELL was effective on atopy dermatitis by modulating Th2 related factors.

The unripe fruit of Poncirus trifoliata Raf has been used for the treatment of allergic disease. Recently it was reported that the fruit inhibits passive cutaneous anaphylaxis and histamine release at mast cell. Type I immediate hypersensitivity of anaphylactic type is caused by released mediate chemical at mast cell. Histamine is also known as one of potent mediate chemical. Also release of mediate chemical is affected by specific stimulation of IgE combined with mast cell. Activation of mast cell is known to be stimulated by compound 48/80 and inhibited by increase of cAMP. In this experiment, the effect of water extract of Poncirus trifoliata Raf fruit (PT) on a histamine release, cAMP concentration and IgE production was measured. Compound 48/80 was administrated to the mouse peritoneal cell which was pretreated with PT. PT dosedependently inhibited histamine release at peritoneal mast cell and the serum level of histamine induced by compound 48/80. PT also instantly increased cAMP level of peritoneal mast cell right after it was added and the level gradually decreased. Production of IgE induced by antigens at mouse peritoneal cell was inhibited by PT. The IgE synthesis is induced by IL-4 and it is known that lipopolysaccharide(LPS) plus IL-4 cause an increase in IgE secretion by murine B cells. The effects of PT inhibited the production of IgE activated by LPS plus IL-4 at human U266B1 cells. These results indicate that PT has antiallergic activity by Inhibition of IgE production from B cells and histamine release by increase of cAMP.

Paragonimus westermani is a tissue migrating parasite in the early stage until arriving at lung, and most of the parasites spend their life spans there. Considerable immune responses including activation of macrophages are taken place during the residence of parasites in the host. However, concerning the immunologic defense mechanisms of the host against this parasite, only a few document is available so far. In this study, the cytotoxic effect of peritoneal macrophages under the presence of antibody and/or complement against metacercariae of F. westermani was investigated in vitro. Metacercarlae were collected from the crayfish, Cambaroides similis and hatched out in Tyrode solution (pH 7.4). Plastic adherent cells from normal or infected rat (Wistar) peritoneal exudates were used as experimental macrophages. Polyclonal antibodies were obtained from infected rats and a cat. Cat IgG was fractioned with ion exchange chromatography. Fresh rabbit complement was used according to experimental scheme. Various combinations of peritoneal macrophages, normal or infected rat serum, complement and cat IgG were incubated at $36^{\circ}C$ in 5% $CO_2$ incubator for 6, 14, 24 and 48 hours. The results obtained were as follows: 1. P. westermani infection activated peritoneal macrophages non-specifically and this activation induced increases of cell adherence and cytotoxicity on metacercariae. 2. In the presence of infected rat serum the antibody.dependent cell-mediated cytotoxicity of peritoneal macrophages on metacercariae was significantly increased and showed a peak at 6-hour incubation. But the cytotoxic effect was markedly reduced after inactivation of complement and heat.labile IgE antibody by the heating of infected serum at 56$^{\circ}C$ for 30 minutes. 3. The highest cytotoxic effect (100%) of concomitant incubation with IgG and complement showed 24 hours after incubation, although cell adherence was relatively low at 6-hour incubation and 0% at 24-hour incubation. 4. Coordinative functions of complement with serum and IgG were effective in cell adherence and in cytotoxicity, but it is not clear the independent role of complement on the macrophage- mediated cytotoxicity in this study- With these results it is assumed that P. westermani infection can induce the non-specific activation of peritoneal macrophages, and strum antibodies including IgE antibody might enhance the cytotoxicity by macrophages,

To evaluate the effects of lactic acid bacteria (LAB) on Peyer's patch cells, mice were treated with a high dose of kanamycin to disturb the gut microbial environment. The overarching goal was to explore the potential of LAB for use as a dietary probiotic that buffers the negative consequences of antibiotic treatment. In vitro, LAB stimulated the production of immunoglobulin A (IgA) from isolated Peyer's patch cells. Inflammation-related genes (TNF-α, IL-1β, and IL-8) were up-regulated in Caco-2 cells stimulated with lipopolysaccharide (LPS), while tight-junction-related genes (ZO-1 and occludin) were down-regulated; the effects of LPS on inflammatory gene and tight-junction gene expression were reversed by treatment with LAB. Mice treated with a high dose of kanamycin showed increased serum IgE levels and decreases in serum IgA and fecal IgA levels; the number of Peyer's patch cells decreased with kanamycin treatment. However, subsequent LAB treatment was effective in reducing the serum IgE level and recovering the serum IgA and fecal IgA levels, as well as the number of Peyer's patch cells. In addition, ZO-1 and occludin mRNA levels were up-regulated in the ileum tissues of mice receiving LAB treatment. Lactic acid bacteria can enhance the intestinal immune system by improving the integrity of the intestinal barrier and increasing the production of IgA in Peyer's patches. Lactic acid bacteria should be considered a potential probiotic candidate for improving intestinal immunity, particularly in mitigating the negative consequences of antibiotic use.

Objective : Juglandis Semen has a function that to invigorate the lung and kidney. And It is commonly used as a supporting agent in the treatment of coughing and bronchitis. This study was performed to investigate the effect of oral administration of Juglandis Semen Extract (JSE) against the experimental asthma induced by ovalbumin. Methods : Asthma was induced to Balb/c mouse by i.p. injection and aerosol immunization with ovalbumin. It was observed the change of the cell number in the BAL fluid. Concentrations of IL-4, IL-5 in splenoc yte were assessed by ELISA, IgG and IgE from serum were calculated by same method. Results : 1. Number of macrophage in BAL fluid was significantly decreased in JSE group compared with control group, but not eosinophil and lymphocyte. 2. Levels of IgG and IgE in serum were significantly decreased in JSE group compared with control group, respectively. 3. Concentration of IL-4 in culture supernatant of splenocyte was significantly decreased in JSE group compared with control group, but there was no significant in IL-5. Conclusion : We found that the effect of JSE extract in asthma was implicated in reduction of IL4released from Th2 cell, and decreases of IgG and IgE from plasma cell. These findings suggest that JSE can produce anti-asthmatic effect, which may play a role in allergen-induced asthma therapy.

Artemisinin, a new antimalarial to treat patients infected with strains of Plasmodium jalciparum, derived from the plant Artemisia annua Linn, has immunopharmacologic actions such as enhence the PHA -induced lymphocyte transformation rate, increased the weight of spleen but reduced the weight of thymus, reduced phagocytic function of peritoneal macrophage, remarkably reduced the level of serum IgG and hemolysin fonning capacity (sentitized with SRBC), inhibited the activity of Ts cells of donor mice by supraoptimal immunuization(SOI), but enhenced activity of Ts cells of recipient mice by SOI. These results suggested that Ts cells may be the target cells of artemisinin. To the serum complement C3 level of plasmodium berghei-infeted mice, artemisinin (i. m,) could remarkly increase it. The artemisinin also obviously reduced the prostaglandin E(PGE) in the mouse hind paw swelling induced by carrageenin. Numerous studies have demonstrated that pharmacologic doses of PGE attenuate the development of immunocomplex nephritis. Some autologous immune mechanisms may be invoolved In the pathogensis of some types of glomurulonephritis. Glomerular abnormalities can be induced in animals by variety of immunological manipulations. The resulting disorder has many clinical and pathogical similarities to the disease in human. Our purpose was therefore to test the ability of the artemisinin to lessen the severity of rabbit IgG accelerated nephrotoxic serum glomerulonephritis in mice model. Mice which had treated with rabbit IgG and NTS, administrated with saline, showed Significant inceases of urinary protein, cholesterol level, and decrease of serum albumin in NS group. On the contrary, By i.g. adminstration of artemisinin at dose of 12.5, 25 and 50 mg/kg for 14 days after NTS injection, shown that artemisinin inhibited the nephritic changes in some parameters by means of urinary protein(p<0.05, p<0.01) and serum choleterol(p<0.05, p<0.01) and albumin (p<0.05, p<0.01), blood urea nitrogen (p<0.05, p<0.01), serum albumin(p<0.05, p<0.01); Cyclophosphamide(i.p. 10mg/kg for 14d) had almost same effect as the artemisinin had. Morphological studies shown that The picture of kidney from the mouse with NTS-nephritis accerated with rabbit IgG, treated with i.g. saline as the control, the mesangiocapillary were enlarged and proliferated; There were inflammatory cells infiltrating around the glomeruli; The ethelial cell were proliferated in the wall of Bowman's capsule. Histopatholological picture of kidney from the NTS-nephritis accerated with rabbit IgG mouse treated with i.p. 10mg/kg cyclophosphamide as the positive control. No siginicant histopathological evidence were found. Treaded with i.p. 12.5mg/kg artemisinine, the picture shown that mesangiocapillary were lightly proliferated; There were inflammatory cells infiltrating around the glomeruli; Treaded with i.p. 25mg/kg artemisinine, The picture shown that the mesangiocapillary were lightly proliferated; Treaded with i.p. 50mg/kg artemisinine, The picture shown that both the mesangiocapillary proliferated and the inflammatory cells infiltrating around the glomeruli are less than treated with saline, 12.5 and 25 mg/kg artemisinine. On the basis of these studies we conclude that the artemisinin can relieve pathological change caused by NTS-nephritis aacerated with rabbit IgG.

In order to demonstrate the effect of specific serum IgG antibody on the adherence of Streptococcus mutans to smooth surface and the mechanism of effective adherence inhibition by IgG antibody, in the present study authors obtained purified IgG from different immunogen preparations of S. mutans NCTC 10449(serotype c) and observed the effect of each IgG preparation on the adherence of each S. mutans strain cultured in different conditions. In addition, the present study was undertaken to observe the cross-reactivity of IgG and the effect of sucrose concentration on the adherence of S. mutans in vitro non-growth condition. The adherence of S. mutans to glass surface was effectively inhibited by serum IgG antibody. At the same IgG concentrations, anti-2% fructose grown/1N NaCl washed S. mutans NCTC 10449 cell showed greater adherence inhibitory effect to S. mutans strains than anti-2% sucrose grown and anti-S. mutans NCTC 10449 cell wall, and the greater inhibitory effects of IgG preparations were observed in assay using 2% fructose grown S. mutans cell preparations than using 0.1% sucrose grown cell preparations. These results suggest that the more effective adherence inhibition by serum IgG antibody is due to the reaction with S. mutans cell surface antigens rather than glucan and cell-associated glucosyltransferase. The greatest adherence inhibitory effect of IgG to S. mutans strains was observed on homologous NCTC 10449 strain and the inhibition cross-reactivities were observed between serotype c, e, and f strains. More pronounced cross-reactivity of adherence inhibition of IgG to S. mutans was observed in assay using anti-2% fructose grown/1N NaCl washed cell than using other IgG preparations, and observed in assay using 2% fructose grown S. mutans cell preparations than 0.1% sucrose grown cell preparations. It was interested that low, but adequate concentration of reactive IgG antibody significantly increased the adherence ability of S. mutans. This result may be due to the formation of small cell aggregates resulted in a increase in the numbers of organisms which adhered to glass surface. The adherence of S. mutans to glass surface was possible in the absence of glucan-synthetic activity. Low level of sucrose significantly increased the adherence ability of S. mutans to glass surface, but excessive amount of sucrose induced large cell aggregates resulted in a decrease in the numbers of organism which adhered.

Background: Nowadays asthma is considered to be an inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia. Production of cytokines by bronchial epithelial cells may contribution to the local accumulation of inflammatory cells in patients with bronchial asthma. In many recent studies molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objectives: We aimed to identify the clinical effects of Chuongsangboha-tang and the effects of Chuongsangboha-tang on serum cytokines in asthmatic patients. Materials and Methods: The subjects consisted of 36 patients with asthma who had been treated with Chuongsangboha-tang for four weeks. Chuongsangboha-tang is an herbal decoction which has been used of the traditional therapeutic agent of asthma. PFT, Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA), blood eosinophil, serum IgE, Serum IL-4, IL-5, IFN- were checked before and 4 weeks after treatments. Results: Treatment with Chuongsangboha-tang for four weeks resulted in significant increase in FEV1.0%, PEFR%, QLQAKA. The blood eosinophil, serum IgE, IL-4 and IL-5 in asthmatic patients increased significantly compared to the normal control group, while the serum IFN-decreased significantly. Conclusions: This study shows that Chuongsangboha-tang has effects on improvement of pulmonary function and quality of life in asthmatic patients. Obviously, further research concerning this is still necessary.
