An experiment was conducted to establish a large scale production method of anti-serum against chicken IgM and to profile the developmental changes of serum IgM levels during the feeding period(from hatching to 7 weeks of age) in broiler chicks. Blood samples were taken from Hubbard chicken at the age of hatching, three days of age, and weekly thereafter till to 7 weeks of age. The pure IgM was isolated from ammonium sulfate treated chicken serum by both sephadex G-200 and sepharose CL-6B chromatography. The breaking-through peak containing IgM appeared from the fraction 26 to 28. These fractions consisted mainly of IgM when tested by anti-chicken IgM(Nordic, Netherlands). Immunized with the heavy chain of this purified IgM, the rabbit immune sera(anti-chicken IgM) were formed a reaction only with the purified chicken IgM. The quantitative assay of serum IgM were carried by RID method. The optimal time for diffusion was 14 hours and the coefficient of determination($R^{2}$) for regression equation of standard curve was 0.992. It was observed that IgM concentrations were the highest at hatching(3.23 mg /mL), after that decreased gradually. From 2 to 5 weeks of age the levels unchanged(2.0 ~ 2.3mg /mL), and gradually decreased to 7 weeks of age(1.3 mg /mL).

An experiment was conducted to establish a large scale production method of anti-serum against chicken IgA and to profile the developmental changes of serum IgA levels during the feeding period(from hatching to 7 weeks of age) in broiler chicks. Blood samples were taken from Hubbard chicken at the age of hatching, 3 days of age, and weekly thereafter till to 7 weeks of age. The pure IgA was isolated from ammonium sulfate treated chicken bile juice by gel filtration chromatography ( Sepharose GL-6B) - The quantitative assay of serum IgA were carried by RID method. Developmental changes of serum IgA concentrations were 0.42 mg /mL at hatching, thereafter dicreased gradually, lowest at 1 week of age(0.17 mg /mL), and gradually increased to 7 weeks of age(2.73 mg /mL). There was no sexual difference in serum IgA level, but female chicks showed higher IgA levels than male chicks during the experimental period.

This work was conducted to examine the variation of immunoglobulins (Igs) in serum, immune milk, normal milk and colostrum upon implantation of a new Antigen Releasing Device (ARD). The core of each ARD housed an immunostimulating complex (ISCOM) that was made of adjuvant Quil A and type XIII lipase from a Pseudomonas sp. Each ARD was coated with polylactic acid, known as polylactide, that controls antigen release. Twenty lactating Chinese Holstein cows were divided into 2 groups (n = 10): test group and control group. All cows in the test group were implanted with a single injection in the right iliac lymph node with 3 types of ARDs, which were designed to release the antigens at d 0, 14 and 28 post-implantation. Blood and milk samples were collected from both groups, and colostrum samples were also collected from other post-partum cows in the same farm. Concentrations of $IgG_1$, IgA and IgM in whey and serum were measured by sandwich ELISA. The results showed that the $IgG_1$, IgA and IgM concentrations in serum and whey from the test group were higher than from the control group. Among the three Igs measured, the $IgG_1$ concentration in serum was significantly higher at d 40 after ARD implantation, and the $IgG_1$ concentration in whey peaked at d 9, 17 and 30, which corresponded with release of the antigen. Based on Pearson's correlation between Ig concentration and production parameters, IgA concentration in normal milk was positively correlated with lactation period, which reflected IgA changes during the lactation period in immune milk. In colostrum, $IgG_1$, IgA and IgM decreased abruptly from d 0 to 3, and then decreased slightly. In conclusion, serum $IgG_1$ concentration can be affected by controlled release of the ARD, while whey IgA levels are primarily affected by lactation period. These results may be useful in future studies designed to regulate concentrations of Igs in immune milk.

In order to investigate the effects of bisphenol A (BPA) on immune system in mice we examined the various immunological parameters. After single oral administration of BPA to female ICR mice, the weights of bodies and lymphoid organs, splenic cellularity and hematological parameters were examined on day 2 and 7. Among them WBC and splenic cellularity were slightly decreased on day 2. To assess the effects of BPA on humoral immune responses, splenic IgM plaque forming cell (PFC) and serum IgM were assayed. When BPA was administered after immunization with SRBC, but not before immunization, IgM PFC against SRBC was significantly lowered in a dose dependent manner. Serum IgM level was also decreased on day 4 when high dose (2000 mg/kg) of BPA was administrated after injection of OVA-antigen. The indexes of splenocyte proliferation (SP) to concanavalin A (Con A) and bacterial lipopolysaccharide (LPS) were measured in vitro by MTT assay. At low concentration BPA slightly increased splenocyte proliferation but at higher concentration it showed significant inhibitory effects on cell proliferation. Mitogen-stimulated SP was also determined with spleen cells from BPA treated mice. Con A-induced SP was slightly decreased and LPS-induced SP was especially inhibited at 1000 mg/kg and 2000 mg/kg of BPA. These results indicate that BPA is able to acutly evoke humoral and cell mediated immune suppression in mice.

본 연구는 면역화된 산란계로부터 생산된 계란 난황중에 들어있는 S. mutans균주의 specific IgY를 분리하여 면역화 여부, Specific IgY 농도별 및 균수별에 따른 항균력을 현미경적 및 탁도측정에 의한 IgY의 항균력 효과를 검토하고자 실시하였다. 면역화 여부에 따른 탁도시험 결과 면역처리된 처리구에 crude IgY를 10%와 20% 첨가에 의해 항균 효과가 있었다. 면역을 하지 않은 닭에서 생산된 계란으로부터 추출한 IgY를 10% 첨가구와 대조구에서는 응집반응을 나타내지 않았다. 그러나 S. mutans로 면역화된 닭에서 생산된 계란에서 추출한 IgY의 10%첨가구는 상등액과 침전물에서는 균들이 응집되는 현상을 보였다. 면역화된 조난황 specific IgY를 첨가한 처리구가 대조구 보다 S. mutans균들이 응집되는 정도에 있어서 확실한 효과를 나타내었다. 조 난황 specific IgY의 농도별 시험에서는 5%이상 첨가구 들에서는 전반적으로 균체들의 응집현상이 나타났으며 IgY를 2.5% 이하로 첨가한 처리구와는 확연한 차이를 보였다. 탁도에 있어서도 조 난황 specific IgY 농도별 시험에서는 첨가농도에 따라 차이가 있었지만 10% 이상 첨가구에서는 탁월한 효과를 나타내었다. 응집된 균괴의 크기는 IgY첨가량이 증가할수록 점점 더 커져가는 현상을 나타내었다. 균수별에서는 $10^5\;cfu/mL$ 이상 접종구에서는 균체들이 응집되는 현상을 보였으며 균수가 많을수록 더욱 응집되는 현상을 나타내었다. Plaque 형성력은 감소하는 경향을 보였으며 IgY 농도 15%에서는 plaque 형성이 약 75%가 저해되었다. 따라서 면역화된 닭으로 부터 생산된 계란에서 추출된 crude IgY를 사용하여 S. mutans균으로부터 발생된 충치를 예방할 수 있을 것으로 사료되었다.

This study was performed to elucidate the histopathologic distribution of immunoglobulins, particularly IgA, IgG and IgM in the periapical lesions, including 22 periapical granulomas and 18 periapical cysts. The immunoperoxidase staining method using reagents manufactured and supplied by Danish DAKO company was employed in this study. In comparison with the immunohistochemical methods, this method was proved to be reliable and convinient one to detect immunoglobulins in the tissue. The following results were obtained: 1. In the 22 periapical granulomas, IgG was found in 20 cases (90.9%), IgA in 16 cases (72.7%) and IgM in 19 cases (86.3%). 2. In the 18 periapical cysts, IgG was found in 16 cases (88.8%), IgA in 13 cases (72.2%) and IgM in 15 cases (83.3%). 3. The distribution of immunoglobulins both in periapical granulomas and periapical cysts was in great diversity according to the lesion and area. 4. More immunoglobulins were found in the exudative area with moderate or severe infiltrations of plasma cells and lymphocytes and less concentration of immunoglobulins were seen in the area with leukocytes infiltration and tissue destruction. 5. The area with collagenolysis and reparative activity contained more abundant IgG and IgM than IgA in periapical granulomas. 6. IgG was dominant in the granulomatous connective tissue and immunoglobulins were not easily found in the fibrous capsule in periapical cysts.

This study was undertaken to observe the relationship between salivary IgA, IgG, agglutinin titer & dental caries. The subjects divided into two groups, an active caries group (AC group) and caries-free and treated caries group (CFTC group). The AC group consisted of 36 subjects who had one or more carious lesions and the CFTC group of 12 subjects who had no evidence of caries or had filled teeth without present carious teeth for the last six months. The IgA, IgG and IgM levels in their saliva were measured by single radial immunodiffusion method using a disposable low-level immunodiffusion plate. The salivary agglutinin titers to Streptococcus mutans were measured by microtitration system. The results were as follow; 1. The mean value of IgA concentration in saliva of AC group was slightly higher than that of CFTC group, but its difference was slight. 2. The mean value of IgG concentration in saliva of AC group was slightly lower than that of CFTC group. The IgM concentration in saliva of both groups was neither below 1.1 mg/dl nor detected on LC partigen immunodiffusion plate. 3. There was no difference in the agglutinin titer to S. mutans antigen by serotypes, but low level agglutinin to type d was measured in both groups. 4. AC group showed low correlation between IgA, IgG & DMFT, but CFTC group revealed negative correlation. 5. The relationship between salivary IgA & agglutinin titers to S. mutans was low correlation in AC group, but CFTC group showed significant positive correlation. (P<0.05) 6. There were no specific correlations among the concentrations of salivary immunoglobulins, agglutinin titers to S. mutans, and the DMF teeth. They had no close concern to induce the dental caries.

감마선 조사된 새우의 신속한 판별을 위한 방법으로 갈색새우의 TPM을 항원으로 하여 개별적으로 생산된 M-IgG와 P-IgG를 이용한 Sandwich ELISA를 분석법으로 확립하였다. M-IgG를 항원 포획을 이한 coating 항체로 사용하고, P-IgG를 포획된 TPM에 대한 반응항체로 사용하였을 때, 12.5에서 50$\mu\textrm{g}$/mL의 농도 범위에서 TPM을 정량할 수 있었다. 감마선 조사된 새우의 TPM 농도는 선량에 의존하며 감소하였고, 감마선 조사와 가열 또는 냉동 등의 병용 처리에서도 선량에 의존하며 감소하였다. 이 결과는 면역분석기법의 하나인 Sandwich ELISA가 감마선 조사된 새우의 검지법으로 이용될 수 있다는 가능성을 나타내었다.
