BACKGROUND : Changiga is a hetnal medicine which has been used of the traditional therapeutic agent of asthma. So I examine the effect of Changija on immune Cell&serum OA-specific IgE in BALF in rat asthma model. MATERIAL and METHODS : Rats were sensitized with OA; at day 1 sensitized group and Changiga(CIG) groups were systemically immunized by subcutaneous ingection of 1mg OA and 300mg of Al(OH)3 in a total volume of 2ml. At the same time, 1ml of 0.9% saline containing $6{\times}109$ B. pertussis bacilli was injected by i.p. 14 days, after the systemic immunization, rats received local immunization by inhaling 0.9% saline aerocol containing 2%(wt/vol) OA, A day after local immunization, BAL fluid was collected from the rats. A day after local immunization, rats were orally administered with Changiga extract 14 days, Lymphocyte, CD4+ T-cell CD8+ T-cell counts, CD4+/CD8+ ratio in BALF, change of serum OA-specific IgE level in the peripheral blood were measured and evaluated. RESULT : Changiga showed a suppressive effect on a rat asthme model. Changiga decreased lymphocyte, CD4+ T-cell, CD4+/CD8+ ratio in BALF, serum OA-specific IgE level as compared with the control group, whereas Changiga decreased CD8+ T-cell in BALF with statistical nonsignificance as compared with the control group. CONCLUSION: This study shows that Changiga have a suppressive effect on rat allergic athma model. Changiga would be useful allergic asthma treatment agent.

Background : There have been many in vitro evidences that interleukin-4(IL-4) might be the most important cytokine inducing IgE synthesis from B-cells, and interferon-gamma(IFN-$\gamma$) might be a main cytokine antagonizing IL-4-mediated IgE synthesis. Recently some reports demonstrated that IFN-$\gamma$ might be used as a new therapeutic modality in some allergic diseases with high serum IgE level, such as atopic dermatitis or bronchial asthma. To evaluate the in vivo effect of IFN-$\gamma$ in bronchial asthma we tried a clinical study. Methods : Fifty bronchial asthmatics(serum IgE level over 200 IU/ml) who did not respond to inhaled or systemic corticosteroid treatment, and 17 healthy nonsmoking volunteers were included in this study. The CD 23 expressions of peripheral B-cells, the IL-4 activities of peripheral T-cells, the serum soluble CD23(sCD23) levels, and the superoxide anion(${O_2}^-$) generations by peripheral PMN were compared between bronchial asthmatics and normal subjects. The IL-4 activities of peripheral T-cells were analyzed by T-cell supernatant (T-sup)-induced CD23 expression from tonsil B-cells. In bronchial asthmatics the serum IgE levels and histamine $PC_{20}$ in addition to the above parameters were also compared before and after IFN-$\gamma$ treatment. IFN-$\gamma$ was administered subcutaneously with a weekly dose of 30,000 IU per kilogram of body weight for 4 weeks. Results : The ${O_2}^-$ generations by peripheral PMNs in bronchial asthmatics were higher than normal subjects($8.23{\pm}0.94$ vs $5.00{\pm}0.68\;nmol/1{\times}10^6$ cells, P<0.05), and significantly decreased after IFN-$\gamma$ treatment compared to initial values($3.69{\pm}0.88$ vs $8.61{\pm}1.53\;nmol/1{\times}10^6$ cells, P<0.05). CD23 expression of peripheral B-cells in bronchial asthmatics was higher than normal subjects($47.47{\pm}2.96%$, vs $31.62{\pm}1.92%$, P<0.05), but showed no significant change after IFN-$\gamma$ treatment. The serum sCD23 levels in bronchial asthmatics were slightly higher than normal subjects($191.04{\pm}23.3\;U/ml$ vs $162.85{\pm}4.85\;U/ml$), and 11(64.7%) of 17 patients showed a decreasing pattern in their serum sCD23 levels after IFN-$\gamma$ treatment. However the means of serum sCD23 levels were not different before and after IFN-$\gamma$ treatment. The IL-4 activities of peripheral T-cells in bronchial asthmatics were slightly higher than normal subjects($22.48{\pm}6.81%$ vs $18.90{\pm}2.43%$), and slightly increased after IFN-$\gamma$ treatment($27.90{\pm}2.56%$). Nine(60%) of 15 patients showed a decreasing pattern in their serum IgE levels after IFN-$\gamma$ treatment. And the levels of serum IgE were significantly decreased after IFN-$\gamma$ treatment compared to initial values ($658.67{\pm}120.84\;IU/ml$ vs $1394.32{\pm}314.42\;IU/ml$, P<0.05). Ten(83.3%) of 12 patients showed an improving pattern in bronchial hyperresponsiveness after IFN-$\gamma$ treatment, and the means of histamine $PC_{20}$ were significantly increased after IFN-$\gamma$ treatment compared to initial values ($1.22{\pm}0.29mg/ml$ vs $0.69{\pm}0.17mg/ml$, P<0.05). Conclusion : Our results suggest that IFN-$\gamma$ may be useful as well as safety in the treatment of bronchial asthmatics with high serum IgE level and that in vivo effects of IFN-$\gamma$ may be different from its in vitro effects on the regulations of IgE synthesis or the respiratory burst of PMN.

Eosinohil and IgE responses of interleukin IL(-5 transgenic and normal C3H/HeN mice were studied after experimental infection with Nippostrongylus brasiliensis 9Nb). Intestinal worms were recovered at day 5 post-infection (PI), and numbers of total white blood cells (WBC) and eosinophils, and total serum IgE and anti-hapten (dinitrophenyl)(DNP) specific IgE titers, were measured at days 0,14 and PI. IL-5 mice appeared resistant to Nb infection showing a significantly ower worm recovery rate than normal mice (P<0.05). Total WBC and eosinophil counts (/mm3) were significantly increased in Nb infected normal mice (p<0.05), but unchanged (total WBC) or decreased (eosinophils) in IL-5 mice at day 21 PI. The total serum IgE level remarkably increased in normal mice, but only a little in IL-5 mice at days 14 and 21 PI. Priming with DNP brought about more remarkable increases of the total and anti-DNP specific IgE in normal mice than in IL-5 mice. The results show that IL-5 mice are resistant to Nb infection, and that eosinophil and IgE responses in these mice are not augmented by N infection.

The experiment was conducted to compare the effects of supplements of copper, vitamin I and selenium on growth and immune responses of broiler chicks fed cornsoy diets. The basal diet contained 21% crude protein, 2,800 kcal ME, 10 mg Vitamin E, 10 mg copper and 0.1 mg selenium per kg diet. Additions of the basal diet were copper (150mg and 250 mg/kg) or combination of vitamin I(200 mg/kg) and selenium(2 mg/kg). Serum immunoglobulin G(IgG) concentrations and body weight gain were determined weekly from hatching to 7 weeks of age. Additions of copper(150mg, 250mg) to the basal diet were showed, at the four weeks of age, 4.8% and 4.5% higher in body weight gain than that of control group, respectively. The active immune system of copper and (Vit. E＋Se) treated groups developed one week earlier than control group(basal diet). Negative correlation between IgG concentration and body weight gain was showed at the period from hatching to three weeks of age and, thereafter, positive correlation were identified (p＜0.01). Mortality rates were observed lower in all treated groups than that of control. In conclusion, the lower the levels of serum IgG, at the first two weeks of age, the lower in disease Infection and the higher in body weight gain.

The effects of aroma mixed oil with Chamomile, Lavender and Sandalwood on atopic dermatitis in NC/Nga mice were examined. The NC/Nga mice were divided into BMAC group, FK 506 Oinment (Tacrolimus Hydrate) group, and CLS group to get curative power of CLS. The amount of total IgE and IgG1 was measured and the severity of atopic dermatitis was assessed by the scoring procedure in NC/Nga mice. Topically applied CLS significantly suppressed the level of serum IgE and IgG1 in NC/Nga mice and FK506, used as reference drugs for atopic dermatitis, also exhibited suppressive effects against level of IgE and IgG1. The level of IgE was lower in the CLS group than in the FK506 group while the serum IgG1 level in the FK506 group was lower than in the CLS group. The treatment with FK506 and CLS reduced the skin inflammation index, especially the severity degree of atopic dermatitis in the skin lesioned NC/Nga mice by naked eyes was improved by treatment of FK506 and CLS. The results suggest that treatment of CLS in NC/Nga mice with atopic dermatitis have an beneficial therapeutic effects on reducing the level of IgE and IgG1 and accelerating repair of skin lesion.

Canine atopic dermatitis (CAD) has a genetic basis and is primarily a skin disorder characterized by allergic features. It is caused by an excessive immune response, associated with immunoglobulin E(IgE), to allergens and shows clinical signs of itching and inflammation. The present study evaluated the allergen-specific and total IgE concentration in dogs with allergic disorders. Allergen-specific IgE analysis was performed using a Multiple Allergen Simultaneous Test (MAST) assay, and total IgE analysis was conducted using an ELISA in 82 dogs with CAD. The subjects were divided into two groups: dogs aged ≤3 years and dogs aged >3 years, enabling a comparison of total IgE concentrations between the two age groups. The results showed that the major affecting environmental allergen was Alternaria alternate, and the major affecting dietary allergen was raw chestnut. The results revealed that dogs aged ≤3 years had higher total IgE concentrations than dogs aged >3 years with significant difference. The results of this study can contribute to the diagnosis and treatment of CAD in South Korea.

This study was performed to investigate the immunopotentiative effects of conjugated linoleic acid on mice immunosuppressed by administratin corticoids. Mice were divided into four groups of 8 mice. Two groups (C, CP) were given diet supplemented with 1% linoleic acid (CLA) and the other two groups (L, LP) were given diet supplemented with 1% linoleic acid (LA) instead of CLA. Prednison was administered to two groups (CP, LP) for immune depression. After feeding diets for 3 weeks containing PDS injection for last 1 week. Serum and gut lumen lavage were taken. Measurement of total Ig were executed using sandwich ELISA. Serum levels of IgA, IgG, and IgM showed some trend which groups fed with CLA were higher than groups fed with LA while IgE was reduced in those fed the CLA intake, and groups administered with PDS were lower than groups administered with saline. However, no significant differences were seen in the proportion of total immunoglobulin in serum. In case of secretory IgA, Group C and CP were significantly higher than group L and LP. Especially between CP and LP, it can be seen effects of CLA. In addition that the CLA treated group weighted a significantly lower level than the one's that have not been treated with CLA. These result support the view that CLA potentiate the immune response and prevent immune depression caused by administrating of corticoids. In conclusion, CLA produced a situation favorable for immunopotentiative effects. Thus, the clinical application of CLA is warranted.

Although wheat is a common staple food in the world, some people suffer from a variety of wheat allergies. For example, wheat-dependent exercise-induced anaphylaxis is induced in the gastrointestinal tract by wheat proteins. Relatively high molecular weight proteins that are salt-insoluble induce many wheat allergies. In the present study, we investigated the induction of an allergy response using crude wheat proteins, which are relatively low molecular weight, salt-soluble proteins. The crude antigen used in this study was extracted using phosphate buffered saline. When the antigen extracts from various wheat cultivars were orally administered, differentiable degrees of allergy responses were observed as measured by serum IgE and histamine secretion compared to the control. Serum IgE levels increased following administration of three of the wheat extracts. This evidence suggests that a combination of salt-soluble wheat proteins could be antigens for the induction of various allergy responses.

The present study compared purification methods of hen egg yolk immunoglobulin (IgY) from the hen immunized with Edwardsiella tarda. The purification of anti-E. tarda IgY was performed by four different methods, polyethylene glycol (PEG), chloroform polyethylene glycol (Chloroform-PEG), ammonium sulfate and purification kit. Purified IgY had heavy chain of 64 kDa and light chain of 27 kDa size. IgY purified from the hen immunized with E. tarda showed higher ELISA values and agglutination titers than those with IgY purified from the non-immunized hen as a negative control. In addition, purified IgY recognized similar E. tarda proteins to those with anti-E. tarda rabbit serum by western blotting. Purified IgY had an agglutination titer of 1:512 by PEG method and ammonium sulfate method, and 1:128 by chloroform-PEG method and purification kit. Moreover, PEG method was the most rapid method among the four different IgY purification methods. These results indicate that PEG method is effective purification method maintaining biological activity of the IgY.
