  • In this study, we have developed shear horizontal(SH) surface acoustic wave(SAW) sensors for the detection of immunoglobulin G(IgG) on the gold coated delay line of SH-SAW devices. As the result of the experiment, we could uniformly immobilize anti-MIgG(mouse IgG) conjugate on the surface of gold. When displaying results of immobilization on the surface of gold using G-anti MIgG conjugate and blocking buffer in frequency shift, G-anti MIgG conjugate showed frequency shift of 75.1 kHz in the initial frequency, and blocking buffer showed frequency shift of 215.7 kHz. When various concentrations of MIgG was added in 100MHz type sensor, the sensor showed 46.3, 127.45, 161.21 and 262.39 kHz frequency shift at 25, 50, 75 and 100 ${\mu}g$ MIgG concentration, respectively.

  • Objectives : The purpose of the present study is to evaluate the effects of herbal acupuncture with Ginseng Radix for the treatment to intestinal disease in the rat with 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) induced colitis. Methods : All animals were subjected to the injection of saline $(300{\mu}{\ell},\;500{\mu}{\ell})$ for a study control or TNBS $(300{\mu}{\ell},\;500{\mu}{\ell})$ into the lumen of the colon, 8cm proximal to the anus through the intestine. Ginseng Radix herbal acupuncture ($20mg/m{\ell},\;0.4m{\ell}$) were injected to the both $Hapgok(LI_4)$ acupoints at 2nd injection of TNBS in rats. Thus, the body weight, RBC count, WBC count, total protein, IgG levels and IgM levels were observed to study the effects of Ginseng Radix herbal acupuncture. Results : Ginseng Radix herbal acupuncture on $Hapgok(LI_4)$ for TNBS-induced colitis inhibited the body weight loss rate but did not affect RBC and WBC counts. Furthermore, it inhibited the reduction of total protein concentration and serum IgG and IgM levels in TNBS induced colitis were recovered. Conclusions : Herbal acupuncture with Ginseng Radix helps recover the TNBS-induced colonic damage and may be an important method for treatment of the colitis.

  • This study was carried out to know the effects of Gwanjul9-bang (hereinafter reffered to GJ9) on the inhibition of arthritis induced by collagen on DBA/1J mouse. For this purpose, GJ9 was orally administered to mouse with arthritis induced by collagen II. Cytotoxicity, hepatotoxicity, arthritis index, value of immunocyte in draining lymph node and paw joint, rheumatoid factor (IgG, IgM) in serum were measured in vivo. The cytotoxicity against hFCs was not measured in any concentration. The hepatotoxicity was low in GJ9 treated group compared with MTX group. The arthritis index was decreased significantly. In total cell counts of DLN and paw joint, the cells in DLN increased significantly while there was significantly decrease in paw joint. In lymph nodes, $CD19^+$, $CD3^+$, $CD4^+$, $CD3^+CD69^+$, $CD8^+$, $CD4^+CD25^+$, $CD3^+CD49b^+$, $CD4^+CD44^+$, $CD3^+CD8^+$ cells increased significantly, $B220^+CD23^+$cells decreased significantly. In joints, $CD3^+$, $CD4^+$, $CD4^+CD25^+$, $CD11b^+Gr-1^+$ cells decreased significantly. The levels of IgG and IgM was significantly decreased compared with control. Anti-collagen II in serum was significantly decreased compared with control. The degree of arthritis induced damage of joint of GJ9 group is slight compared with control group in histopathologic observation (Hematoxylin & Eosin, Masson's Trichrome). Comparison of the results for this study showed that GJ9 had immunomodulatory effects. So we expect that GJ9 should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

  • To examine the effects of HHCP on atopic dermatitis and its various immunopathologic parameters was induced by DNCB in NC/Nga mice and the animals were orally administrated with HHCP. We summarized the results obtained from serum levels of IgE and the numbers of various immune cells as follow. HHCP has no cytotoxic effects at the range of concentration (1-400 ${\mu}g$/ml) on fibroblast isolated from lung of BALB/c mice. HHCP significantly lowered the serum levels of IgE compared with control at 16 and 20 week. HHCP significantly reduced the number of CD19$^+$ cell in spleen and DLN, as well as the number of B220$^+$ /IgE$^+$ cell in DLN compared with control. HHCP significantly reduced the number of ${\alpha}$${\beta}$ TCR$^+$ in spleen and DLN, the number of CD8$^+$ in spleen compared with control, and also significantly reduced the number of CD3$^+$, CCR3, CD3$^+$/CD69$^+$, CD3/ CCR3, CD4$^+$, CD3$^+$/ CD4$^+$/CD45$^+$ cell in DLN. HHCP increased the number of NK$^+$ cells in spleen compared with control, in contrast significantly decreased the number of CD11c$^+$/ Classll$^+$ cell and CD11b$^+$/Gr-1$^+$ cell in DLN. Taken together, these results suggested that HHCP has suppressive effects on atopic dermatitis through the inhibition of IgE production and modulation of immune cell population in NC/Nga mice.

  • This study has been carried out to secretion antibodies for the purpose of preventing the infection of Helicobacter pylori and using them as a supplement for treatment. This experiments have been separated antigens from H. pylori and observed into antibody production and the agglutination of H. pylori for the separated antigens. As major antigenic proteins separated from H. pylori, the following could be verified: 12 kinds of band for whole cell (WC), seven kinds of band for outer membrane protein (OMP), three kinds of band for crude urease, and one kind of band for lipopolysaccharide (LPS). The IgG anti-H. pylori antibody of separated antigens showed $77.9{\pm}6.4{\mu}g/ml$ for we (L), $84.9{\pm}6.4{\mu}g/ml$ for OMP, and $123.8{\pm}2.9{\mu}g/ml$ for crude urease, at the same antigen concentration of $20{\mu}g/100ull$, which showed the most at the crude urease. And it turned out that the IgA antibodies were generated with $2.5{\pm}0.32{\mu}g/ml$ for WC (L), $2.0{\pm}0.43{\mu}g/ml$ for OMP, and $1.3{\pm}0.25{\mu}g/ml$ for crude urease, which demonstrated the most for WC (L) antigens. As a result of verifying the immunogenecity of antigenic protein through the Western blotting, major antigenic substances could be confirmed as follows: 10 kinds for WC, six kinds for OMP and three kinds for crude urease. The agglutination values on the H. pylori of the antibody were $2^5,\;2^5,\;2^6\;and\;2^7$ at the antigen serums of anti-WC (H), anti-WC (L), anti-OMP and anti-crude urease, respectively, which indicated the highest for the antigen serum of anti-crude urease. The urease activation-inhibiting absorbance of antigen serum created by each antigen was $0.14{\pm}0.01$ for WC (H), $0.16{\pm}0.01$ for WC (L), $0.18{\pm}0.03$ for OMP, and $0.18{\pm}0.04$ for urease, demonstrating a significant inhibiting effect, compared with $0.26{\pm}0.02$ of the control group.

  • The purpose of this study was to investigate the immunomodulatory effects of Alpina officinarum (AO) ethanol extract on immunocompromised mice. The mice were injected intraperitoneally with an immunosuppressive drug, cyclophosphamide, and then administrated orally with 30, 100, and 300 mg/kg of ethanol extract of AO (AO 30, AO 100, and AO 300, respectively). The concentrations of cytokines and immunoglobulins (IgM, IgA, IgG) in serum were measured. The body weight of the mice and spleen cell number of the AO-fed group showed no significant difference compared to a control group. The concentrations of several cytokines, including IL-2, IFN-${\gamma}$, and TGF-${\beta}$, in serum showed a significant increase in the AO 100 group compared to the control and other groups (p<0.05). The IL-4 level showed no significant difference in the experimental groups. The supplementation of AO (30, 100, 300 mg/kg) significantly increased the concentration of IgM (p<0.05). The concentration of IgA was significantly increased in the AO 100 group (p<0.05) compared to the control group. It can be concluded that AO ethanol extract enhances immune function by promoting the production of cytokines and immunoglobulins.

  • Objective: Two experiments were conducted using 28 healthy multiparous sows to evaluate the oxidative stress status and reproductive performance of sows during gestation and lactation under different thermal environments. Methods: Fourteen multiparous sows were used in Exp. 1 under a high thermal environment, and the other 14 multiparous sows were used in Exp. 2 under a moderate thermal environment. In both experiments, reproductive performances of sows were recorded. Plasma samples were collected on d 35, 60, 90, and 109 of gestation, and d 1 and 18 of lactation for malondialdehyde, protein carbonyls, 8-hydroxy-deoxyguanosine, immunoglobulin g (IgG), and IgM analysis. Results: For sows in Exp. 1, plasma malondialdehyde concentration on d 109 of gestation tended to be greater (p<0.05) than it on d 18 of lactation. Plasma concentration of protein carbonyl on d 109 of gestation was the greatest (p<0.05) compared with all the other days. Plasma concentrations of 8-hydroxy-deoxyguanosine on d 109 of gestation was greater (p<0.05) than d 18 of lactation in Exp. 1. For sows in Exp. 2, there was no difference of malondialdehyde and protein carbonyl concentration during gestation and lactation. In both Exp. 1 and 2, litter size and litter weight were found to be negatively correlated with oxidative stress indicators. Conclusion: Sows under a high thermal environment had increased oxidative stress during late gestation indicating that increased oxidative damage to lipid, protein, and DNA could be one of the contributing factors for reduced reproductive performance of sows in this environment. This study indicates the importance of providing a moderate thermal environment to gestating and lactating sows to minimize the increase of oxidative stress during late gestation which can impair reproductive outcomes.

  • Pollen has been used for prevention or treatment of certain diseases such as diabetes arthritis or cancer in traditional medicine. Among various pollens, pine tree pollen is known to relieve hypertension, suppress fatty liver progression, and facilitate the digestion, but its immunological activities are less known. To evaluate immunological reactivities and immunotoxicities of pine tree pollen, BALB/c mice were administered to the poller through oral route. Pine tree pollen suspended in distilled water or extracted with methanol has been administered at the concentration of 0, 10, or 100 mg/kg five days per week for four weeks. Polyclonal activation of splenic T cells with phytohemagglutinins did not induce a significant difference in IL-4 and $IFN_{\gamma}$ production between the pollen-administered mice groups and the control mice. Furthermore, polyclonal activation of splenic B cells with lipopolysaccharides did not result a significant difference in IgG1 and IgG2a production among the groups. These findings imply that the intake of pine tree pollen does not bring any humoral and cellular immune-dysrequlation. Whereas, viability of Listeria monocytogenes was suppressed in the mice administered with 100 mg/kg bw methanol extract, indicating the potential ability of pine tree pollen to enhance cell-mediated immunity mediated by type-1 helper T cells. In addition, aberrant upregulation of plasma IgG1 level was observed in the pollen-administered mice, which suggests a possibility of allergic response induction through the pine tree pollen uptake. Overall, pine tree pollen-mediated modulation of humoral or cellular immunity is worthy of further systematic investigation.
