  • 본 실험은 생봉독 처리가 돼지의 체액성 면역반응에 대한 생봉독의 효과를 조사하기 위하여 실시하였다. 혈중 Immunoglobulin(Ig) G, IgA, IgM의 농도에 미치는 생봉독의 효과를 조사하기 위하여 모돈 3두에서 생산한 자돈 20두(LY ×D)를 생봉독 처리군과 대조군으로 각각 10두씩 배치하였다. 생봉독 처리군은 출생시와 3일령에 교소혈 (GV-1), 해문혈(ST-25) 및 두구혈(CV-8), 6일령에 거세, 단미 창상부위에 생봉 1마리씩 직침 시술하였고, 대조군은 생리식염수 1ml를 동일한 혈위에 주입하였다. 혈중 Ig 농도 측정을 위하여 출생시와 3일, 7일, 14일 및 21일령에 채혈하여 Immunoturbidimetric method로 IgG, IgM, IgA를 측정하였다. 지표항원으로 사용한 돈 콜레라와 위축성비염 백신에 대한 생봉독의 항체 생성효과를 조사하기 위하여 모돈 5두에서 생산된 자돈 40두(LY×D)를 생봉독 처리군과 대조군으로 각각 20두씩 공시하였다. 생봉독 처리군은 출생시에 교소혈(Jiao-Chao, GV-1), 해문혈(Hai-Men, ST-25) 및 두구혈(Du-Kou, CV-8)에, 3일령에 단미 및 거세시술 시 창상부위에 생봉독을 처리하였고, 21일령 이유시에는 교소혈(GV-1)과 백회혈(Bai- Hui, GV-20)에 생봉독을 처리하였다. 지표항원으로 위축성비염 백신은 24일령과 44일령에 접종하였고 돈콜레라 백신은 44일령과 64일령에 각각 접종하였다. 항체가 분석용 혈액은 24, 34, 44, 54 및 74일령에 채혈하여 위축성비염은 시험관응집반응, 돈콜레라는 ELISA법에 의하여 항체가를 조사하였다. IgG 농도는 처리군에서 출생시 339.52, 3일령에 366.48, 7일령에 296.52, 14일령에 242.06, 21일령에는 219.06mg/dl이었고 대조군은 각각 347.10, 333.14, 243.28, 205.18 및 191.58mg/dl 이었다. 처리전(출생시)에는 처리군과 대조군간에 유의차가 없었으나 처리군의 IgG 농도가 대조군에 비하여 3일령 10.3% (P<0.02), 7일령에는 21.9% (P<0.01), 14일령에는 18.0% (P<0.07), 21일령에는 14.3(P<0.07) 더 높게 나타났다. IgA와 IgM의 농도는 전체기간동안 처리군과 대조군간에 유의차가 인정되지 않았다. 돈콜레라 virus에 대한 항체역가는 처리군에서 대조군에 비하여 24일령 때 57.0%(P<0.03), 34일령 때 74.6% (P<0.006), 44일령에 48.6% (P<0.017), 54일령 때 45.0% (P<0.16), 74일령 때 44.4%(P<0.006)가 유의하게 높은 것으로 나타났다. 위축성비염 원인균인 Bordetella bronchiceptica에 대한 항체역가는 처리군이 대조군에 비하여 34일령 때는 39.7%(P<0.002), 44일령 때 31.9% (P<0.02), 54일령 때에 33.4%(P<0.01), 74일령 때에는 57.3%(P<0.007)가 높게 나타나 접종일인 24일령을 제외하고 전체기간에 걸쳐 높은 항체수준을 보였다. 위의 결과를 종합해 볼 때 돼지에 대한 생봉독 처리는 면역기능향상 효과가 있는 것으로 사료된다. 이와 같은 결과를 볼 때 돼지에 대한 생봉독의 처리는 양돈 생산성면에서 생봉독 처리는 돼지의 생존율을 높이고, 증체량이 높았다는 조 등(2005)의 보고를 뒷받침하고 있어 양돈 산업발전에 기여할 것으로 사료된다.

  • The growth and immune responses to endotoxin lipopolysaccharide (LPS) challenge ( $20{\mu}g/kg$) of piglets with and without a iron dextran injection (Fe, 200 mg/head) two days after birth are compared. Sixty-four newborn piglets from eight litters were allocated randomly to one of four treatments. The control received no iron dextran and only saline (Sal) injection on the second and fifteenth day after birth (Sal-Sal). The remaining three groups received Fe-Sal, Sal-LPS, Fe-LPS treatments respectively. On fifteen days of age, blood samples of piglets were taken at 0 h, 1 h, 2 h and 4 d after saline or LPS injection to determine immune functions and blood characteristics. The trial terminated when the pig reached 56 days and the average daily gain of piglets was then measured. Daily gain, serum immunoglobulin G (IgG) concentration and red blood cell counts did not vary significantly among the four groups at any measuring times. Serum tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) concentration increased sharply 1 h after LPS injection. However, iron injection did not change TNF-${\alpha}$ concentration responds to LPS injection. White blood cell counts of two LPS injection groups were significantly lowered 1 h following the injection. In contrast, serum lactoferrin concentration had increased significantly 1 and 2 h postinjection. Furthermore, iron injection produced no further effects on these two criteria. Iron injection increased the hemoglobin (Hb) concentration of piglets at any measuring time, and LPS injection lowered Hb concentration. In conclusion, a 200 mg/head of iron dextran injection on the second day after birth increased Hb concentration, had no detrimental effect on the immune responses and growth of piglets. Moreover, if creep feed (175 mg Fe/kg feed) is provided from d 7 after birth, the Fe-injection does not contribute to overall performance of piglets and may not be a necessity in practice.

  • Objectives : Ulcerative colitis and Crohn's diseases are chronic inflammatory disease of the gastrointestinal tract identified mainly for diarrhea, stomachache, hemafecia. The source and pathologic mechanism about ulcerative colitis and Crohn's disease are still unknown but stress, infection, a genetic factor, environmental factors etc. may be the cause of chronic inflammatory disease of the gastrointestinal tract recently. Methods : Because ulcerative colitis and Crohn's disease is recognized as Ha-ri(下痢) or Jang-Byok(腸?) in Oriental Medicine, Rhizoma Coptidis Herbal acupunctures were injected in hapgok $(LI_4)$ which is used to treat intestinal disease in clinic. All animals were subjected to the injection of saline $(300\;{\mu}l,\;500\;{\mu}l)$ for a study control and TNBS $(300\;{\mu}l,\;500\;{\mu}l)$ into the lumen of the colon, 8cm proximal to the anus through the intestine. Rhizoma Coptidis Herbal (20 mg/ml, 0.4 ml) acupuncture solution was injected to the $LI_4$ (both hands) at the secondary injection time of TNBS in rats. And body weight, RBC count, WBC count, total protein, Paw edema rate, rate of protein leakage into CMC-pouch fluid, IgG levels and IgM levels were observed to study the effects of Rhizoma Coptidis Herbal acupuncture in hapgok $(LI_4)$. Results : In results, Rhizoma Coptidis Herbal acupuncture in hapgok $(LI_4)$ on TNBS-induced colitis reduced the rate of weight loss but had no effect on RBC and WBC count. And it reduced total protein concentration, paw edema, rate of protein leakage into CMC-pouch fluid, IgG levels and IgM levels. Conclusion : Data suggest that injection of Rhizoma Coptidis herbal acupuncture solution into hapgok has significant therapeutic effect on the colitis.

  • Objective : Membranous nephropathy (MN) is the most common cause of adult nephrotic syndrome worldwide. MN has been defined as granular subepithelial deposition of IgG immune complexes along the glomerular basement membrane (GBM). We aimed to identify the effects of Chungyeolmaksungbang (CYMSB) treatment on cBSA-induced in MN mouse model. Methods : The effect of Chungyeolmaksungbang treatment was studied on the morphology and protein excretion in the cationized bovine serum albumin (cBSA)induced mouse chronic serum sickness nephritis model. One group of mice was given intra-peritoneal (i.p.) immunizing doses of cBSA and complete Freund's adjuvant. One week later, these animals began a single i.p. injection of cBSA for 4 weeks. A second group followed the same injection protocol, but was given CYMSB p.o. Results : Proteinuria significantly was decreased and serum albumin was increased in the group treated with cBSA and CYMSB extract compared with the control. Serum BUN was significantly decreased on CYMSB compared with control. CD3e+/CD19 cells ratio of peripheral blood was decreased and CD4+/CD8 cells was increased. Level of $IL-1{\beta}$ was significantly decreased, and $IFN-{\gamma}$ was significantly increased. Concentration of IgG and IgM was significantly decreased compared with control. Thickness of GBM was decreased on histological analysis of kidney. Deposition of CD4 and CD8 was decreased on immunohistochemical staining of kidney. Conclusions : We conclude that CYMSB treatment may could be a useful remedy agents for treating the MN with cBSA.

  • Oregonin is known as a representative active substance of plants of the Alnus species. In this study, we will show the results of establishing a method for extracting trace amounts of useful substances in plants. Additionally, a variety of physiological activity studies were conducted with extracts containing high content of useful substances. In this study, anti-oxidant, anti-inflammatory and anti-allergic activities of supercritical fluid residue 60% EtOH extracts of Alnus sibirica (ASCFR) were investigated in vitro. To explore anti-oxidant and anti-inflammatory characteristics of supercritical extract, DPPH radical scavenging, and ABTS radical scavenging activity, inhibition of nitric oxide production in LPS-stimulated RAW 264.7 cells and ${\beta}$-hexosaminidase release in IgE-stimulated RBL-2H3 cells were examined, respectively. Results showed a concentration-dependent increase in DPPH and ABTS radical scavenging activity. Cells stimulated with LPS produced more nitric oxide than normal control cells. However, cells treated with supercritical fluid residue 60% EtOH extract decreased production in a concentration-dependent manner. In anti-allergic activity studies, ASCFR showed concentration-dependentanti-allergic activity. Based on results and strong antioxidant activity, ASCFR has potential as basic research materials for development of therapeutic supplements-based medicines or functional cosmetics related to chronic inflammatory skin immunity diseases.

  • $Schizandra$ $chinensis$ Baillon is a traditional folk medicine plant that is used to treat and prevent several inflammatory diseases and cancer in Korea, but the underlying mechanisms involved in its anti-allergic activity are not fully understood. This study was designed to investigate mechanisms of anti-allergic activity of a $Schizandra$ $chinensis$ Baillon water extract (SCWE) in immunoglobulin E (IgE)-antigen complex-stimulated RBL2H3 cells and to assess whether gastric and intestinal digestion affects the anti-allergic properties of SCWE. Oxidative stress is an important consequence of the allergic inflammatory response. The antioxidant activities of SCWE increased in a concentration-dependent manner. RBL-2H3 cells were sensitized with monoclonal anti-dinitrophenol (DNP) specific IgE, treated with SCWE, and challenged with the antigen DNP-human serum albumin. SCWE inhibited ${\beta}$-hexosaminidase release and expression of interleukin (IL)-4, IL-13, and tumor necrosis factor-alpha (TNF-${\alpha}$) mRNA and protein in IgE-antigen complex-stimulated RBL2H3 cells. We found that digested SCWE fully maintained its antioxidant activity and anti-allergic activity against the IgE-antigen complex-induced activation of RBL-2H3 cells. SCWE may be useful for preventing allergic diseases, such as asthma. Thus, SCWE could be used as a natural functional ingredient for allergic diseases in the food and/or pharmaceutical industries.

  • Drug delivery to the brain may be achieved by producing chimeric peptide, attaching the drug to protein 'vectors' which are transported into the brain from the blood by a receptor-mediated transcytosis through the blood-brain barrier (BBB). Since the BBB expresses high concentrations of transferrin receptor, and it was reported that anti-transferrin receptor mouse monoclonal antibody (OX26) undergoes transcytosis through the BBB, it is logical to assume that a drug delivery system via transferrin receptor-mediated transcytosis is a promising strategy. In the present study, therefore, we tested feasibility of several OX26 based vectors for the brain delivery of a model drug. Avidin-based delivery vectors such as OX26-streptavidin (OX26-SA), OX26-neutralite avidin (OX26-NLA) were chemically synthesized vectors and OX26 immunoglobulin G 3 type $C_{H}3$ fusion avidin $(OX26\;IgG3C_H3-AV)$ was genetically engineered. To improve the efficiency of producing chimeric peptide, we used avidin-biotin technology. Pharmacokinetics of $[^3H]biotin$ bound to OX26-SA, OX26-NLA and $OX26\;IgG3C_H3-AV$ was determined by intravenous injection technique, and their stabilities in plasma were analyzed using HPLC. The brain delivery of $[^3H]biotin$ bound to OX26-SA, OX26-NLA and OX26\;$IgG3C_{H}3-AV$ (expressed as %ID/g brain) was $0.22{\pm}0.01$, $0.18{\pm}0.01$ and $0.25{\pm}0.09$, respectively. The areas under the plasma concentration versus time curve (AUC) for OX26-SA, OX26-NLA, $OX26\;IgG3C_H3-AV$ from time zero to 60 min were $209{\pm}10$, $195{\pm}9$, $134{\pm}29\;%ID\;min/ml$ respectively and their total clearances $(CL_{tot})$ were $1.00{\pm}0.09$, $1.08{\pm}0.07$ and $1.54{\pm}0.29\;ml/min/kg$, espectively. These results showed that these vectors possess preferable pharmaceutical (e.g., resonable stability) and pharmacokinetics (e.g., significant brain uptake and enhanced AUC) for brain delivery. Therefore, these vectors may be broadly useful in the brain delivery of drugs that are not transported into the brain to a significant extent.
