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: The serum immunosuppressive acidic protein (IAP) has been reported to be a useful tumor marker for renal cell carcinoma. In a previous study, the serum levels of IAP were shown to be related to the TNM stages and the nuclear grades in patients with renal cell carcinoma. The effectiveness of the IAP as a follow-up marker for renal cell carcinoma was evaluated. MATERIALS AND METHODS: In 135 patients who underwent a radical or partial nephrectomy for renal cell carcinoma, the serum concentrations of the IAP were measured by radial immunodiffusion preoperatively and postoperatively every 3 months. The changes in the serum IAP levels in the follow-up were recorded, and the change in the recurrence group was compared with that of the non-recurrence group. RESULTS: The mean age of 135 patients (male 87, female 48) was 52.2 12.3 (18-86) years. At follow-up, metastatic recurrences were observed in 8 patients an average of 18.4 months after surgery. The metastatic lesions were found in the bone in 3 patients, the liver in 2, the lung in 2 and the spleen in 1. In patients with an increased serum IAP preoperatively, the IAP levels were significantly lower 7-9 months postoperatively (p<0.05) (from 752.4 296.8microgram/ml to 465.9 88.9microgram/ml). With the metastatic recurrence, the serum IAP level was continuously higher. CONCLUSIONS: The serum IAP might be a valuable tool in following up a renal cell carcinoma for a postoperative recurrence.

It is known that antithrombin III is a potent vasodilator and plasmin is a vasoconstrictor, and some patients with a subarachnoid hemorrhage(SAH) develop clinical vasospasm and some patients do not. Under the hypothesis that the development of clinical vasospasm might depend on the difference of the blood level of antithrombin III in each patient with SAH and that the plasmin might have a role in the development of clinical vasospasm, we repeatedly checked the levels of blood antithombin III with a single radial immunodiffusion method and CSF fibrinogen degradation products(FDP : indirect indicator of plasmin activity) with a latex-test(Thrombo-Wellcotest(R)) during the period between 1-4, 5-11 and 12-24 days after a SAH in 29 patients. 10 patients with diseases except those with a SAH were selected as a control group. First, we analyzed the difference of the average of blood antithrombin III and CSF FDP between aneurysmal SAH patients and control patients and then, between patients with clinical vasospasm(8 cases) and patients without clinical vasospasm(21 cases). Secondly, we also analyzed the difference of these data between patients with clinical vasospasm and patients without clinical vasospasm according to the sampling day after a SAH. As a result, there was no statistical difference between the average blood level of antithrombin III in control and in SAH patients(29.06+/-3.04 vs. 25.61+/-6.95, respectively), and in patients with clinical vasospasm and in patients without clinical vasospasm(26.59+/-7.65 vs. 23.67+/-7.40, respectively). The average CSF levels of FDP is higher in SAH patients than in control patients(18.16+/-14.36 vs. 1.00+/-3.16, respectively : p<0.01). It is also higher in patients with clinical vasospasm than in patients without clinical vasospasm. However, there is no statistical significance(28.75+/-9.91 vs. 21.75+/-12.07, respectively : p>0.05). In the analysis of the average CSF levels of the FDP according to the sampling day after a SAH, even though the average levels is higher in patients with clinical vasospasm than in patients without clinical vasospasm(1-4 days : 31.43+/-14.64 vs. 27.33+/-16.24, 5-11 days : 23.75+/-17.68 vs. 18.10+/-16.32, 12-24 days : 32.50+/-13.89 vs. 18.82+/-16.54, respectively), a statistical significant difference was noticed only in levels which were checked between 12 and 24 days after a SAH(p<0.05). This study concludes that the blood level of antithrombin III shows no difference between the control and SAH patients, and patients with clinical vasospasm and patients without clinical vasospasm. Although it suggests a causal relationship between the FDP itself or plasmin in CSF and the development of clinical vasospasm, it does not justify any valid conclusion.

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.

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).

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.

OBJECTIVE: Systemic Lupus Erythematosus(SLE) is characterized by various autoantibodies to a variety of nuclear antigens. Certain extractable nuclear antigens(ENA) have been served as extremly useful aids in differentiation of clinical subset, diagnostic marker and in the detection of early forms of systemic rheumatic diseases. This study was to employ immunoblot to determine the prevalences of antibodies to ENA in SLE compared with immunodiffusion. METHODS: Sera were obtained from 127 SLE patients. Antibodies to ENA were assessed by double immunodiffusion (DID) and immunoblot method. RESULTS: Using the immunblot method, the prevalences of antibodies to ENA were as follows: The antibody to Sm was 27%, UIRNP 33.6%, Ro 41.8%, La 14%, ribosomal P 14% and Ku 4%. The prevalences of antibodies to ENA by DID were as follows: The antibody to Sm was 15%, RNP 24.5%, Ro 54.3% and La 9.4%. CONCLUSIONS: Compared with immunodiffusion, results using immunoblot showed greater sensitivity in the detection of autoantibodies to ENA in SLE.
