Since IgG4-related pancreatitis was first reported in 2001, IgG4-related disease has been identified in other organs such as salivary gland, gallbladder, thyroid, retroperitoneum and kidney; but lung invasion is rare. A 63-year-old man presented with hemoptysis at the pulmonary clinic and chest computed tomography revealed about 4.1 cm irregular shaped mass with spiculated margin at the left upper lobe. Despite no elevation of serum IgG4 level, he was finally diagnosed as IgG4-related lung disease by transthoracic needle biopsy. After treatment with oral glucocorticoids, hemoptysis disappeared and the size of lung mass was decreased.

Purpose: The purpose of this study was to compare serum amyloid A (SAA) protein levels with high-sensitive C-reactive protein (hs-CRP) levels as markers of systemic inflammation in patients with chronic periodontitis. The association of serum titers of antibodies to periodontal microbiota and SAA/hs-CRP levels in periodontitis patients was also studied. Methods: A total of 110 individuals were included in this study. Patients were assessed for levels of hs-CRP and SAA. Nonfasting blood samples were collected from participants at the time of clinical examination. The diagnosis of adipose tissue disorders was made according to previously defined criteria. To determine SAA levels, a sandwich enzyme-linked immunosorbent assay was utilized. Paper points were transferred to a sterile tube to obtain a pool of samples for polymerase chain reaction processing and the identification of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Tannerella forsythia. The serum level of IgG1 and IgG2 antibodies to P. gingivalis, A. actinomycetemcomitans, and T. forsythia was also determined. Results: SAA and hs-CRP levels were higher in periodontitis patients than in controls (P<0.05). In bivariate analysis, high levels of hs-CRP (>3 mg/L) and SAA (>10 mg/L) were significantly associated with chronic periodontitis (P=0.004). The Spearman correlation analysis between acute-phase proteins showed that SAA positively correlated with hs-CRP (r=0.218, P=0.02). In the adjusted model, chronic periodontitis was associated with high levels of SAA (odds ratio [OR], 5.5; 95% confidence interval [CI], 1.6-18.2; P=0.005) and elevated hs-CRP levels (OR, 6.1, 95% CI, 1.6-23.6; P=0.008). Increased levels of serum IgG2 antibodies to P. gingivalis were associated with high levels of SAA (OR, 3.6; 95% CI, 1.4-8.5; P=0.005) and high concentrations of hs-CRP (OR, 4.3; 95% CI, 1.9-9.8; P<0.001). Conclusions: SAA and hs-CRP concentrations in patients with chronic periodontitis are comparably elevated. High serum titers of antibodies to P. gingivalis and the presence of periodontal disease are independently related to high SAA and hs-CRP levels.

Pork is an excellent source of essential nutrients such as protein. However, pork can trigger hypersensitivity and serum albumin of pork is known as major allergen. In this study, to evaluate the effect of gamma irradiation on the allergenicity of porcine serum albumin (PSA), PSA solution was irradiated at 3, 5, 7, 10, 15, and 20 kGy. The changes in the ability of PSA to bind IgG and patient's serum caused by gamma irradiation were observed by ci-ELISA and immunoblotting. SDS-PAGE was used for measuring the conformational change of gamma-irradiated PSA. The ability of 3-kGy-irradiated PSA to bind p-IgG and patient's serum was decreased to 30% and 15%, respectively. The binding ability showed no significant differences among all irradiated samples. SDS-PAGE showed that the irradiated PSA bands were degraded and aggregated. Immunoblotting of irradiated PSA revealed that IgG and patient's serum were rarely recognized at 3 kGy. Therefore, gamma irradiation could be applied to less-allergenic pork products.

Eight 2-day-old SPF Chickens were each inoculated Orally With 3 Sing1e dose Of 5 × 105 oocysts of Cryptosporinium boilevi. and immunoglobulin G (IgG) antibody responses were chronologically measured by indirect immunofluorescent antibody (IFA) assay. Anti-C. bcileyi IgG antibody levels remained high (1 : 106.67 to 1:512.00) for at least 4 months with 330 days of a detectable period. Ten days after the negative conversion, each chicken was re-challenged with 1 × 107 oocysts of the same species. Subsequent infection in 340-day-old individuals caused sudden elevated IgG antibody levels and the titer peaked on day 28 postchallenge inoculation (PCI), at 1:1.024 with a 65 days of detection period. Chickens in primary infection showed oocyst shedding profiles. but did not exhibit any oocyst shedding before or after experimental reinfection.

Background: The aim of this study is to confirm that peripheral blood sampling for measuring of serum immunoglobulin can predict immunological changes after xenograft implantation. Material and Method: Between March 2006 and January 2007, 19 patients were enrolled (10 xenograft implantation group, 9 control group). Through 3 peripheral blood samples, we measured changes in serum immunoglobulin G and M levels preoperatively, and 2 and 10 days postoperatively. Result: In both groups, serum immunoglobulin levels showed similar changes-they decreased 2 days postoperatively, then increased up to the baseline levels 10 days postoperatively. However, this postoperative change of immunoglobulin G and M was not significantly different in absolute value or pattern between the 2 groups (Ig G; p-value=0.393, Ig M; p-value=0.193). Conclusion: We could not predict immunological changes after xenograft implantation by measuring serum immunoglobulin levels by simple blood sampling. Direct checking of ${\alpha}$-Galactose antibody may confirm an immunological reaction after xenograft implantation.

This studies were to investigate the effects of low power wavelengths Helium-Neon Infra-Red(He-Ne 1R) laser on the changes of the serum immunoblobulin(Ig) concentrations in bum rats, The thirty Spraque-Dawley adult male rats were assigned to the 5 groups: the experimental groups(3). the bum control group(1) and the control group(1). There was made three degree burn by the 290 mW IR on the back oreach rats, from 3 days after being burned. the experimental laser groups were irradiated low power wavelengths(292Hz- 1168Hz, 4672Hz) He-Ne IR laser far 5 minutes every day during the 7days. The results were as follows; 1. The concentrations of immunoglobulin G(Ig G) in serum of all experimental groups on the treated with the low power wavelengths of the He-Ne IR laser during the 5 minutes far 7 days were significantly lower than those of bum groups, but those 1168 Hz group were significantly higher than those of the 292 Hz and 4672 Hz groups. 2. There were significantly decreased the change of the level of immunoglobulin M(Ig M) in serum of all experimental groups on the treated with 5 minutes laser fer 7 days to the burn control group. and were significantly increased on treated with more higher wavelengths groups to those of lower groups. 3. The concentrations immunoglobulin E(Ig E) in serum of the 292Hz wavelengths groups were significantly lower than those in bum control group. As above results. the changes of the immunoglobulin in serum levels on the healing process have meaningful effected with the low power wavelengths role on the treated with He-Ne IR laser.

542 periodontal patients having early-onset periodontitis(EOP) have been reclassified into a more homogeneous phenotypic subsets by newly revised radiographic criteria. Representative patients of each EOP subform have been examined of serum IgG subclass antibodies against periodontopathic bacteria, Porphyromonas gingivalis(Pg) 381 and of genetic markers for IgG allotypes to clarify the relationship between these parameters and phenotype expression of each subform. The early onset periodontitis could be reclassified by the radiographic parameters combining the mean interproximal alveolar bone loss(BL) and the radiographic ratio(between 1st molars and the adjacent teeth: Ratio) with statistical significance(p<0.001 by MANOVA). Moreover these EOP subforms could clearly be delineated from adult periodontitis. Of subform I and II(localized type EOP) patients with minimal mean bone loss(BL<5.0), patients demonstrating disease activities in localized areas(Ratio.>1.5) showed the elevated responses in all the IgG subclasses against Pg compared with those of patients without disease activity(Ratio <1.5). There were gradual increase in the IgG2 and IgG4 titers against Pg as the disease developed into the generalized forms suggesting the possible role of these antibodies in modulating the phenotype expression. The genetic marker study for IgG allotype revealed that mean IgG2 and IgG4 subclass titers were significantly higher(p<0.01, p<0.05, respectively) in patients who were positive for G2m(n). This indicated that IgG subclass responsiveness against the bacterial antigens are under the immnuogenetic control. The observed frequencies of G2m(n) were significantly higher (p<0.05) in subfrom IV patients who had the characteristic features of classical rapidly progressing periodontitis indicating the possible genetic predisposition in these patients.

In order to observe the antigenic localization in the tissues of the adult Clonorchis sinensis, immunogold labeling method was applied using serum immunoglobulins (IgG) of either worm·infected rabbits (group I) or antigen-immunized rabbits (group II) (by the body quid obtained from the adult worms). The electron micrographs of the sectioned worm tissue antigens, embedded in Lowicryl HM 20 medium and stained with protein A-gold complex (particle sixte: 12 nm), were compared between the group I and group II. The gold particles were observed in the interstitial matrix of the worm parenchyma, the epithelial lamellae of the cecum, and the cecal lumen both in group I and II. But the particles were in general more concentrated in group II. The gold particles were not observed on the basal lamina of the tegument or on vitelline glands in group I, while they were highly concentrated on those areas in group II. There were also differences in the antigenicity of interstitial matrix(reacted with group I IgG) and head part(reacted with group II IgG) of the sperm cells in the seminal receptacle. Conclusively, it is suggested that the substances comprising the basal lamina of the tegument or vitelline glands act as specific antigens reacting with antigen(body quid) immunized rabbit IgG. On the other hand, the substances in the cecal lumen and cecal epithelial lamellae are thought to be the specific antigen that react with the worm-infected rabbit IgG.

Objectives : In the theory of Korean medicine, Pear has long been considered to protect throat, bronchus and lung. Pear has been believed to remove sputum in Korean people. This study was conducted to investigate the effect of pear ethanol extract (PEE) on asthma induced by ovalbumin in mice. Methods : We investigated the effects of PEE on airway hyperresponsiveness to methacholine, production levels of ovalbumin (OVA) specific total immunoglobulin G (IgG), IgG1, IgG2a and IgE in serum and histopathological changes of lung tissues in asthamtic mice. Results : PEE decreased airway hyperresponsiveness to methacholine significantly compared to non-treated asthmatic mice (P<0.05). Level of OVA specific IgE in serum was lowered by oral administration of PEE effectively (P<0.05). In histopathological observation, administration of PEE reduced infiltration of immune cells into lung tissue. Conclusion : These results suggest that pear has anti-asthmaitc action and related mechanims are involved in anti-inflammatory action such as reducing level of OVA specific IgE and immune cell infiltration.
