Objectives : The aim of this study was to confirm the characteristics of oral malodor patients by evaluating the differences of salivary flow rate, secretory immunoglobulin A (sIgA) level in saliva between the patient and control groups, and the correlation with the tongue coating, volatile sulfur compound (VSC), salivary flow rate and sIgA level in saliva in the patients group. Methods : Forty-seven patients with oral malodor and twenty healthy volunteers were included in this study. Their tongue coating was assessed with the Winkel tongue coating index, and salivary flow rate, sIgA concentrations in saliva and the level of VSC in oral cavity were measured. Results : There were no significant differences of the salivary flow rate and the sIgA level in saliva between the patient and control groups, but there was a significant relationship between the accumulation of tongue coating and the level of VSC in oral cavity. Conclusions : Our results suggest that tongue coating is closely related to oral malodor, but further studies are needed to confirm the relationship between tongue coating and sIgA level in saliva.

Bickerstaff's brainstem encephalitis (BBE) is a rare disorder with acute ophthalmoparesis, ataxia, consciousness disturbance, and pyramidal signs of suspected autoimmune origin. A-62-year-old woman developed acute diplopia, dysarthria, gaze-paretic nystagmus and gait ataxia. Her mental status fell subsequently into stupor. Brain MRI and nerve conduction study showed no significantly abnormal findings. Electroencephalography revealed diffuse low voltage slowings. After treating with intravenous immunoglobulin, she demonstrated rapid clinical recovery. This case suggests that immunoglobulin can be an alternative option in BBE treatment, especially when plasmapheresis and corticosteroids are difficult or contraindicated.

We investigated changes of immunoglobulin G (IgG) concentrations by heating and drying condition. Also it is performed to group for commercial product by promoting of IgG preservation and reducing of protein denaturation. The result was that content of IgG in colostrum was higher than normal milk. Especially, IgG content of colostrum within 12 hrs after parturition was over 44.67mg/ml and it is 60 times of normal milk. IgG contents was reduced rapidly according as passage of the time. IgG content of the sample heating at 30min at 65$^{\circ}C$ was still a little higher that heating for 10sec at 72$^{\circ}C$. IgG denaturation of heat treatment at 100$^{\circ}C$ for 10sec was lower than at 85$^{\circ}C$ for 30min. We investigated the changes of IgG concentrations of kinds of market milk different with heating processing. This result showed that IgG denaturation ratio by ultra high temperature pasteurization (UHT) was higher than long time low temperature pasteurization (LTLT). On the other hands, IgG content by spray drying was 14.5mg/g and freezing drying was 10.8mg/g. It showed that denaturation of protein content by freezing drying was more than spray drying.

BSA로 면역시킨 드렁허리의 혈청에서 lgM 유사면역글로불린의 정제한 후 그 구조적 특성을 구명하였다. 면역후 항혈청에서는 항원특이 항체능이 증가되었다. 정제된 lgM 유사면역글로불린은 199kD의 분자량을 갖는 단량체 4개가 결합된 800kD의 단백질이었으며, 단량체는 70kD인 H-사슬 2개와 29.5kD인 L-사슬 2개가 결합된 형태였다. 또한 드렁허리의 lgM 유사면역글로불린은 lgM의 특성과 같이 포유류 적혈구에 대하여 약한 응집력을 나타냈다.

Dietary conjugated linoleic acid(CLA) has been shown to affect immune function. Thus, the objective of this study was to investigate the effects of CLA on the mice that treated prednisone. Mice were randomized into 6 groups and fed diet containing either 0(control, P), 0.5%(CLA1, CP1) or 1.5%(CLA2, CP2) CLA for Sweets. Before 1 week of finishing diet supplement CP1, CP2, and P group treated the prednisone by subcutaneous injection. The levels of serum immunoglobulin A, G, E, gut lumen s-IgA, MLN immunoglobulin A, body weight, mucosal protein was compared. The level of serum IgA in CLA1, CLA2, CP1, and CP2 group increased, while which of P group was decreased. The level of serum IgG in CLA 1 group increased, while which of the other group no differences. Serum IgE level showed no difference and the immunoglobulin production in MLN lymphocyte in CLA 1 group increased. The level of gut lumen s-IgA in P group showed decreased, while which of the other group showed no differences. These results support the view that CLA supplement partially enhance the cell-mediated immunity and overcome the immunosuppressive effect of prednisone.

Immunoglobulin M (IgM) of sevenband grouper (Epinephelus septemfasciatus) was purified by mannan-binding protein (MBP) affinity column. The purified IgM had an apparent molecular weights of 76 (heavy chain) and 28 (light chain) kDa in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Eight hybridoma clones secreting monoclonal antibodies (mAbs) against sevenband grouper IgM were established. Antibody detection enzyme-linked immunosorbent assay (ELISA) with bovine serum albumin (BSA, antigen) and the 8 mAbs revealed that optical density (OD) values were clearly different between sera from BSA-immunization and non-immunization of sevenband grouper. These results suggest that the produced mAbs in this study are specifically reacted with IgM of sevenband grouper.

Multicentric Castleman disease (MCD) is an uncommon systemic lymphoproliferative disorder that may cause multiple organ damage. Castleman disease-associated diffuse parenchymal lung disease (DPLD) has not been well studied. A 32-year-old man was referred to our hospital for progressive generalized weakness, light-headedness, and dyspnea on exertion for more than one year. Laboratory evaluations showed profound anemia, an elevated erythrocyte sedimentation rate, and an increased C-reactive protein level with polyclonal hypergammaglobulinemia. Chest radiography, computed tomography (CT), and positron emission tomography-CT scan demonstrated diffuse lung infiltration with multiple cystic lesions and multiple lymphadenopathy. In addition to these clinical laboratory findings, bone marrow, lung, and lymph node biopsies confirmed the diagnosis of idiopathic MCD (iMCD). Siltuximab, an interleukin-6 inhibitor, and glucocorticoid therapy were initiated. The patient has been tolerating the treatment well and had no disease progression or any complications in 4 years. Herein, we report this case of human herpesvirus-8-negative iMCD-associated DPLD accompanied by multiple cystic lesions, multiple lymphadenopathy, and polyclonal hypergammaglobulinemia with elevated immunoglobulin G (IgG) and IgG4 levels. We recommend a close evaluation of MCD in cases of DPLD with hypergammaglobulinemia.

Polymeric immunoglobulin receptor (pIgR) mediates the transfer of polymeric immunoglobulin to protect organisms and is one of the most important mucosal effectors. In this study, the developmental stage- and tissue-specific expression of pIgR were observed before virus inoculation in olive flounder. pIgR was gradually expressed until the formation of immune tissue, exhibiting high expression in the late juvenile period; thereafter, pIgR expression gradually decreased and exhibited high expression in the spleen and skin. Moreover, pIgR expression after viral hemorrhagic septicemia virus infection was high in the kidney and spleen tissues at high density and low at low density. The results of this study can provide a basis for future studies on breeding density, virus expression, and immune system studies in fish.

면역글로불린 G4 (immunoglobulin G4; 이하 IgG4) 관련 질병은 한때는 장기별 별개의 질환으로 진단되었던 질환들을 근래에 공통적인 병리학적, 혈액학적 및 임상적 특징을 가지는 면역 매개 질환을 일컫는다. 이 분류의 질환은 다양한 장기를 침범할 수 있으며, 두경부 역시 침범할 수 있다. 두경부를 침범하였을 경우, 주로 눈물샘, 안와, 갑상선, 뇌하수체 및 뇌수막 등을 주로 침범한다. 이에, 초기 급성중이염과 유양돌기염으로 증상으로 내원한 65세 여자환자에서 안면신경, 뇌경막, 비인강과 경부임파절에 동시에 발생하여 자기공명영상과 조직검사로 진단된 IgG4 연관 질환에 대하여 증례 보고를 하고자 한다.

본 연구에서는 조류에서 종 특이적인 DNA 염기서열변이를 검증하기 위하여 닭, 꿩, 칠면조, 메추리의 immunoglobulin light chain constant domain 유전자를 클로닝하여 DNA염기서열을 분석하였다. 종간에 구별이 가능한 DNA 염기서열변이가 위의 유전자에서 관찰되었다. PCR을 이용하여 종을 구별하기 위하여 종 사이에 특이적인 DNA 염기서열 부위에 한 쌍의 종 특이적인 프라이머를 제작하였다. 또한 비교실험을 위하여 이미 알려진 cytochrome b와 tapasin 유전자에서도 두 쌍의 종 특이적 프라이머를 제작하였다. PCR결과 세 쌍의 프라이머 모두 종 특이적으로 DNA를 증폭하였다. Immunoglobulin 유전자의 염기서열 변이를 이용한 종 특이적인 PCR 방법은 조류의 유전자원 보존을 위한 이종간 카이메라 연구에 유용하게 이용될 수 있을 것이다.
