This study was performed to evaluate the changes of serum IgG4 level in children with allergic diseases. Serum Ige, IgG and IgG4 level were measured using enyzme immunoassay (IgE) and radial immunodiffusion method (IgG and IgG4) in 21 children with bronchial asthma, allergic rhinitis or urticaria Eosinophil counts in peripheral blood and the values of serum IgE were significantly increased in allergic patients. The values of IgG4 in allergic patients were also increased compare to those in controls (24.23mg/dl versus 20.33mg/dl). But the values of IgG4 were not significantly correlated to either IgG or IgE levels. Further studies will be needed for measuring allergen specifie IgE and IgG4 levels considering the onset of diseases, methods and duration of treatment.

The concentrations of three immunoglobulins (IgG, IgA, and IgM) were studied in sera of 307 healthy children from the age of one month to 16 years. The method used was a single radial immunodiffusion technique, with the use of commercially available antibody agar plates. The results obtained were compared with those found in umbilical cord sera and with the average levels in healthy adults. The average concentration of IgG was lowest at the age of 3 months, i.e. about 40 percent of adult level. At the age of one year the average level of IgG was 50 percent of adult level and approached the adult level at the age of 6~8 years (Fig. 1,4 and 5 and Table 1). In cord sera IgA could only be demonstrated in three neonates out of 20. At the age of one year an average IgA level of about 25 percent of adult level was found and the adult level was reached at age of 12 to 16 years(Fig. 2, 4 and 5, and Table 1). IgM was detected in all cord sera with an average concentration of 15 percent of adult level. At the age of 3 months the IgM values were about 50 percent of adult level and at the age of one year approximately 70 percent(Fig. 3,4 and 5, Table 1).

PURPOSE: All IgG subclasses such as IgG1, IgG2, IgG3 and IgG4 can be transferred from mother to fetus through the placenta, though the amount of each IgG subclass is different from one another. Maternally acquired immunity might have an important role for the protection against the infections. We studied transplacental passage of IgG subclasses. METHODS: In this study, we observed the transplacental passage of IgG-subclasses in 22 paired samples of maternal and full- term fetal cord sera. Gestational ages varied from 37 to 42 weeks. The concentrations of IgG subclasses were analyzed by radial immunodiffusion method using commercialized Human IgG Subclass Combi kit. RESULTS: The concentrations of IgG subclasses, IgG1, IgG3 and IgG4 in cord sera exceed the maternal concentration, while IgG2 did not. The ratio of serum levels of cord to maternal were 1.330+/-0.067 for IgG1, 0.859+/-0.039 for IgG2, 1.258+/-0.058 for IgG3 and 1.159+/-0.038 for IgG4. CONCLUSION: This result suggested that the placenta may play a selective barrier for passage of IgG2.

We examined the incidence of anti-Ro antibodies with sera from 60 Korean patients with systemic lupus erythematosus(SLE) by double immunodiffusion. Among these 60 sera tested, 31(51.7%) showed evident immunoprecipitations against Ro antigen on the Ouchterlony plates. Several recent studies indieate that the anti-Ro antibody occurs much less frequently in Occidental lupus patients(around 30%) than in Japanese lupus patients (50%). These data may be suggestive that the racial or ethnic baekground might be an important factor determining the serological, and perhaps the clinical features of SLE.

BACKGROUND: To interpret the serotyping data from group A streptococcal infections and their complications, serotyping data from healthy children are essential. In this study, we determined the serotypes of the strains isolated from the elementary school children located in Seoul and Chinju. METHOD: Eighty-two strains of group A streptococci isolated from Seoul and 76 strains from Chinju were serotyped with T typing, serum opacity reaction (SOR), opacity factor (OF) and M typing. T typing was undertaken by slide agglutination after trypsinization of bacteria, SOR and OF typing by microwell technique and M typing by Ouchterlony double immunodiffusion after Lancefield's extraction method. RESULTS: In Seoul T 12 (52.4%), T 3 (9.8%), T 5 (8.5%) and T 27 (8.5%) were frequently encountered. In Chinju T 12 (44.7%), T 28 (13.2%) and T 6 (7.9%) were commonly identified. While M 12 (48.8%) and M 5 (14.6%) were most common in Seoul, M 12 (26.3%), M 22 (14.5%) and M 28 (10.5%) were widely distributed in Chinju. SOR positivity was 15.9% in Seoul and 54.0% in Chinju respectively. CONCLUSIONS: The distributions of serotypes of group A streptococci between the two areas were more or less different. Serotyping of strains from healthy children may be considered as the basic data to understand the epidemiology of bona fide group A streptococcal infections and disease association of virulent strains.

PURPOSE: The purpose of this study is to observe the salivary immunoglobulin level in whole saliva of infected patients and also to investigate the changes of immunoglobulin level according to its management. MATERIALS AND METHODS: Thirty infected patients who have been admitted to the dept. of oral and maxillofacial surgery of Pusan National University Hospital have been selected as subjects and we analysed the changes of immunoglobulin level of 1.5~3.0ml of unstimulated whole saliva collected throughout four times; the day before treatment, the first day after treatment, the third day after treatment and the day before discharge. We also compared them with immunoglobulins in whole saliva that was collected from 4 normal persons as control group. In radial immunodiffusion technique with BACKMAN(Array 360 system, McLean, USA), level of immunoglobulins was analyzed. RESULTS: The isotypes of Ig that have been found in saliva of normal persons were IgG, IgA, IgM and IgE and their mean level was 8.23, 36.41, 4.38, and 2.38 respectively. In the infected patients before the treatment, the level of IgG, IgA was remarkably higher than that of normal persons, however we could not find the difference on the level of IgM, IgE. As the infection was healing, the level of IgG, IgA was decresing significantly.

This study was performed to investigate associations between serum alpha(1)-antitrypsin(AAT) concentration and radiological categories of coal workers' pneumoconlosis(CWP), between AAT concentration and pulmonary complications such as tuberculosis and emphysema, and to study associations between AAT concentration and FEV(1.0)% in CWP patients, We classified 254 CWP patients in D Hospital into categories of small opacity profusion. And we selected 86 subjects by with or without emphysematous finding in each categories by proportional stratified sampling method. Semm AAT concentrations were quantkated by single radial immunodiffusion method, and the findings of chest radiographs were evaluated by radilogist. The results were as follows: 1. Serum AAT concentrations were not significantly different among groups of radiological categories of small opacities. 2. Complication of emphysema was associated with smoking habits sigmficantlyl(chi square=12.16, p<0,01). And AAT concentraLion was higher in smokers and ex-smokers than in non-smokers. Serum AAT concentration was significantly higher in the cases with emphysema than in the cdses without emphybema{p<0.01). 3. Serum AAT concentration of the group with active pulmonary tuberculosis was significantly higher than with inactive or without: pulmonary tuberculosis group(p<0.1). 4. Serum AAT concentration of the group with low FEV(1.0)% was significantly higher than with high or normal group(p<0.05).
