The purpose of this study is to investigate the age-and sex-related changes in the pH of resting saliva, viscosity, microorganisms and immunoglobulin A of stimulated whole saliva, and to investigate their correlations. The 120 healthy subjects were included in this study and the author used cone-and plate digital viscometer for viscosity, MSB agar for Streptococcus mutans, SL Rogosa agar for lactobacilli, and single radial immunodiffusion technique for immunoglobulinA. The obtained results were as follows : 1. There was no significant difference in pH, viscosity, Streptococcus mutans lactobacilli and immunoglobulin A of the saliva between males and females. 2. The viscosity values of stimulated whole saliva showed the increasing pattern with aging. 3. DMFS (or dmfs) rate was not correlated with pH, viscosity, Streptococcus mutans, lactobacilli and immunoglobulin A of the saliva. 4. There was a significant difference in the concentration of immunoglobulin A between the group under 10 and groups above 10. 5. The viscosity values of stimulated whole saliva showed the increasing pattern with decreasing of the number of Streptococcus mutans.

Periapical lesions develop as a result of immunopathologic response to irritants from infected root canal systems. Removal of these irritants from the root canal system and sealing the root canal space may induce he31ing of the periapical lesions. 83 periapical lesions diagnosed as periapical abscess, periapical granuloma, chronic nonspecific inflammation, fibrosis and periapical Cyst were evaluated for the distribution of immunoglobulin containing cells. The influence of the state of root canal treatment on the distribution of immunoglobulin containing cells has evaluated. All lesions were divided into a group with no treatment, a group with canal enlargement, a group filled with gutta percha, and a group filled with Vitapex(calcium hydroxide). The distribution of immunoglobulin-containing cells according to the presence of pain and fistula was also evaluated. The following results were obtained. 1. Statistically significant difference in the distribution of immunoglobulin-containing cells among periapical abscess, periapical granuloma, chronic nonspecific inflammation/fibrosis and periapical cyst were found.(Kruskal-Wallis analysis, P<0.05) The number of immunoglobulin-containing cells in fibrosis was remarkably lower than that of periapical abscess, granuloma and cyst. 2. IgM and IgA containing cells were predominantly observed in periapical abscesses and periapical cysts, respectively. 3. All periapical lesions showed a large number of IgG containing cells followed by IgM, IgA and IgE containing cells. 4. There was a decrease in all Ig-containing cells in the group with canal filling compared to groups without treatment or with enlargement. That is, there is a decrease in Ig-containing cells as treatment progresses. 5. No significant correlation existed between the presence of pain and fistula and the distribution of immunoglobulin containing cells in periapical lesions.(t-test) Results appear to support that immune response are actively involved in the development and progress in periapical lesions. The fact that distribution of immunoglobulins differ according to the state of endodontic treatment suggests that root canal treatment may alter the humoral immune response of the periapical lesions.

Background: There were several studies comparing prognostic factors in Guillain-Barre syndrome treated with intravenous immunoglobulin and plasmapheresis. However, there were controversies in what were significant factors and there were few studies so far comparing the therapeutic outcomes in patients treated with immunoglobulin. This study was aimed to determine the prognostic factors which affected the therapeutic outcome of Guillain-Barre syndrome treated with intravenous immunoglobulin. Method: We retrospectively reviewed the medical records of patients with Guillain-Barre syndrome admitted to our hospital between January 1999 and March 2004. All patients were treated with intravenous immunoglobulin. Outcome and prognosis were followed up after four weeks using the overall disability sum score. Results: Thirty-six patients were enrolled in this study. According to the clinical and electrophysiological findings, 17 patients were AIDP, 10 were axonal forms, two were mixed and seven had electrophysiologically no evidence of abnormalities. At a follow-up of four weeks, disabilities at the nadir (p<0.001) and admission (P<0.012), initial manifestations of bulbar symptom (P<0.024) and electrodiagnostic features (P<0.013) were significantly correlated with outcome in patients treated with intravenous immunoglobulin. But only disabilities at the nadir (P<0.033) and electrodiagnostic features (P<0.018) were significant in the multivariate logistic regression analysis. Conclusion: Among the patient treated with intravenous immunoglobulin, the outcomes were significantly different according to the neurological status at the nadir. Therefore early diagnosis, administration of intravenous immunoglobulin and preventing complications during acute stages are essential to minimize neurological deficit and shorten the periods of recovery.

We report the result of a high-dose intravenous immunoglobulin therapy in a Henoch-Schnlein purpura patient with severe abdominal pain and nephrotic syndrome who did not respond to methylprednisolone pulse therapy. Kidney biopsy showed diffuse mesangial cell proliferative glomerulonephritis with fibrocellular crescent formation in approximately 50% of glomeruli. Mesangium of all glomeruli were strong positive for IgA and C3 antibodies. High-dose intravenous immunoglobulin treatment was introduced and dramatic improvement of gastrointestinal symptom and proteinuria as well as hematuria was noted. Immunoglobulin administration should be considered in Henoch-Schnlein purpura patients with steroid-resistant intractable gastrointestinal manifestation and renal involvement.

This study investigated the relationship between dental caries and various oral factors in subjects with Down's syndrome. We compared 25 subjects with Down's syndrome with 63 healthy control. The dental caries index and plaque index were examined, and the total salivary immunoglobulin A and S. mutans specific salivary immunoglobulin A concentration were measured using ELISA. The S. mutans counts, Lactobacillus counts and buffer capacity were measured with Dentocult test medium. The decayed and filled surface index of deciduous teeth in subjects with Down's syndrome was lower than in controls(p<0.001). The plaque index and total salivary immunoglobulin A concentration showed no difference, S. mutans specific salivary immunoglobulin A concentration and buffer capacity in subjects with Down's syndrome were lower than in controls(p<0.001). There was no significant difference between two groups in the S. mutans counts and Lactobacillus counts. In 9-11 year age group, S. mutans counts in subjects with Down's syndrome was lower than in controls(p<0.001) and S. mutans specific salivary immunoglobulin A concentration was lower(p<0.05). There was a high correlation among deciduous dental caries index and buffering capacity and S. mutans counts.

Objective : The immune system is a complex of systems, all of which work together to clear infection from the body. In Korea, red ginsenghas been one of the herbs most widely used to enhance the immune system for thousand of years. More recently, red ginseng has been reported to have many positive effects on the immune system. The purpose of this study was evaluate the effects of Korean red ginseng and Chinese red ginseng on IgG, IgM, and IgA, using immunoglobulin productivity assay. Methods : Male SD rats were separated into 3 groups. We administered Korean red ginseng (KRG) to one group and Chinese red ginseng (CRG) to another, with normal saline for the Control group consecutively and orally for 3 months. The dose of red ginseng was 500mg per day, as a powder with soluble water. Immunoglobulin levels from spleen cell were estimated by ELISA kit. Results : In immunoglobulin productivity assay (cell), the IgG level of the KRG group significantly increased but there was no significant difference in the IgG of the CRG group. The IgM level of the KRG group significantly increased stimulated with PWM. When it was unstimulated, the level of IgM in KRG and CRG increased together. The IgA level of the KRG group significantly increased when it was stimulated with PWM and unstimulated. Conclusion : According to the above results, oral administration of red ginseng for 3 months is considered useful for immunomodulatory effect, and Korean red ginseng may be superior to Chinese red ginseng in that effect.

Immunoglobulin G4 (IgG4)-associated autoimmune hepatitis (AIH) is a very rare subtype of autoimmune hepatitis and characterized by marked elevated serum IgG and hepatic infiltration of IgG4-expressing plasma cells. Pathologic confirmation of hepatic IgG4-expressing plasma cells is usually required for the final diagnosis of IgG4-associated AIH. Herein, we report the case of a 47-year-old female diagnosed with autoantibody-negative IgG4-associated AIH mimicking lymphoproliferative disorders.
