Purpose : We aimed to evaluate predictive parameters for non-response to intravenous immunoglobulin (IVIG) in patients with Kawasaki disease (KD) before IVIG use using two controls. Methods : We evaluated 229 consecutive KD patients who were treated with 2 g/kg of IVIG at a single center. Those who had persistent fever >24 hours after IVIG infusion made up the 23 IVIG non-responders; the first control included a total 206 defervesced cases and the second control included 46 cases that were matched for age and pre-treatment fever duration to non-responders. Results : Demographic and clinical characteristics were similar in IVIG non-responders and responders at presentation. As for laboratory findings, the neutrophil differential, CRP, AST, ALT, and LDH were higher, and lymphocyte differential, total protein, albumin, platelet count, and total cholesterol were significantly lower in IVIG non-responders compared to responders by univariate analysis in both study designs. However in multivariate analysis, non-responders showed a significantly higher neutrophil differential (cutoff value, >77%, sensitivity 68.4% and specificity 79.5%) and lower cholesterol (<124 mg/dL, sensitivity 79% and specificity 70.5%). Whereas plasma albumin (<3.6 g/dL, sensitivity 73.7% and specificity 60%) was the sole laboratory parameter of non-responders in the second study design. Conclusion : Severity of inflammation in KD was reflected by higher or lower laboratory values at presentation. Because the multivariate analysis for these indices may be influenced by some confounding factors, including the numbers of patients of different ages and fever duration, other assessment modalities are needed for KD patients with the greatest risk of coronary artery lesions.

This study was conducted to investigate the effect of dietary egg yolk antibody (IgY) powder supplementation on the growth performance, blood component profile, intestinal microflora, and immunoglobulin G in ducks. A total of 300 1-day-old ducks (Cherry Valley) were randomly divided into 5 groups, with 3 replicates of 20 birds. The treatment groups were the negative (NC), positive (PC), egg yolk antibody powder 0.1% (T1), egg yolk antibody powder 0.5% (T2), and egg yolk antibody powder 1.0% (T3) groups. In the growth performance of ducks during the entire experimental period, the IgY groups and positive control group (PC) showed significantly higher (P<0.05) body weights and body weight gains compared to the negative control group (NC). However, no significant differences were observed in the feed intake and feed conversion ratio. The blood component profiles showed that the IgY 0.1 and 1.0% groups decreased in total cholesterol content compared to the NC group. The aspartate aminotransferase (AST) and alanine aminotranferease (ALT) contents were lower in the IgY 1.0% group, but there were no significant differences. Regrading the leukocyte content after feeding IgY, the heterophil: lymphocyte ratio decreased in the IgY groups, especially in the IgY 0.1% group, which had a lower content than the other groups. However, these results showed no significant differences. The Lactobacillus count in the intestines significantly increased (P<0.05) in the IgY 0.1 and 0.5% groups, the level of IgY increased, and the Escherichia coli count decreased. However, no significant difference was observed in the total plate count. The immunoglobulin G content was lower in the IgY groups than in the NC group, and compared with the IgY groups, the IgY 0.5% had a lower content, which was not a significant difference.

Purpose : We evaluated the effects of intravenous immunoglobulin(IVIG) on level of laboratory parameters examined serially according to the existence of coronary artery lesions in children with Kawasaki disease. Methods : Children with Kawasaki disease(n=63), treated with IVIG at a dose of 2.0 g/kg, were classified as a group with coronary artery lesions(CALs+ group, n=9) or a group without coronary artery lesions(CALs- group, n=54). Levels of various laboratory parameters were determined three times during admission; before, 24 hrs after and 7 days after IVIG administration. Results : There were no significant differences in laboratory parameters performing at, before and 7 days after IVIG administration. However WBC and neutrophil counts, and CRP were significantly higher, and the level of albumin was significantly lower at 24 hrs after IVIG administration. Conclusion : Approximately 15% of patients with Kawasaki disease showed CALs in the acute stage. Kawasaki disease patients with CALs were associated with persistent elevated levels of inflammatory parameters including WBC count, neutrophil count and CRP examined 24 hours after IVIG administration.

The purpose of this study was to investigate the changes of serum immunoblobulin and DHEAs when 8 weeks of combined exercise and peony intake have been held to women in their 40s and 50s. 15 participants were chosen, divided into three groups, and they had undergone combined exercise with the level of 1RM 60~70%, HRmax 60~70%, three times a week for 60 minutes each. For the proper intake, 6g of peony were warmed in a double boiler with water 107ml, and the crude liquid was ingested 100ml each by the participants, everyday before breakfast, for 8 weeks. The following conclusions were obtained through these objectives and procedures. First, the amount of immunoglobulin has increased in two groups, the 8-week combined exercise group and the group which undergone both the peony intake and the combined exercise, but did not show the significant difference(p>.05). Second, the results of DHEAs showed an increas in two groups, the 8-week combined exercise group and the group which undergone both the peony intake and the combined exercise, but did not show the significant difference(p>.05). Therefore, the consumption of peony and complex exercise in this study did not positively affect the immune function and dementia prevention.

The olive flounder, Paralichthys olivaceus is susceptible to viral hemorrhagic septicaemia virus (VHSV) at $15^{\circ}C$ but no mortality at $20^{\circ}C$ even though the virus can grow well in vitro at $20^{\circ}C$. Thus, we designed an experiment to know immune response of olive flounder against VHSV when the host reared at $15^{\circ}C$ or $20^{\circ}C$. cDNA microarray analysis was performed to compare the gene expression patterns of the kidney cells between the host reared at $15^{\circ}C$ or $20^{\circ}C$. The expression of MHC class I, IL-8, myeloperoxidae and endonuclease G-like having function for the antigen presentation and chemokine-factor were up-regulted both the $15^{\circ}C$ and $20^{\circ}C$ during VHSV infection. MHC class II gene existing on antigen-presenting cells and B cell lymphocytes, immunoglobulin (Ig) genes and phagocytosis related genes were down-regulated at $15^{\circ}C$ but highly expressed at $20^{\circ}C$. It can be thought that innate immune related antigen presentation by MHC class I and phagocytosis reaction against VHSV are efficiently occur both the temperature but macrophage or B cell related antigen presentation via MHC class II fails to induce downstream immune reactions (adaptive immunity) to make antibody, and it can be one of the reason that causes high mortality only at $15^{\circ}C$.

Purpose : To investigate renal toxicity of high-dose intravenous immunoglobulin(IVIG) in children with Kawasaki disease and idiopathic thrombocytopenic purpura. Methods : 23 children with Kawasaki disease and 7 children with idiopathic thrombocytopenic purpura who were treated with high-dose IVIG(2 g/kg) were evaluated for the change of urine output, blood urea nitrogen(BUN), serum creatinine(Scr), creatinine clearance(Ccr), tubular reabsorption of phosphorus(TRP), fractional excretion of sodium(FENa), 24hour urine ${\beta}_2$-microglobulin/creatinine(${\beta}_{2}MG/cr$) ratio and urine microalbumin/creatinine(MA/cr) ratio at post-IVIG 1 and 3 day. Results : There was no significant change of urine output, BUN, Scr, Ccr, TRP, 24hour urine ${\beta}_{2}MG/cr$ and MA/cr ratio after high-dose IVIG treatment. Transient increase of FENa at post-IVIG 1 day was the only significant change. Conclusion : There was no significant renal toxicity of high-dose IVIG in children with Kawasaki disease and idiopathic thrombocytopenic purpura who had normal renal function.

The present study evaluated effect of egg yolk immunoglobulin (IgY) from the hen immunized with Edwardsiella tarda. The purification of anti-E. tarda IgY was performed by polyethylene glycol (PEG). Purified IgY had heavy chain of 64 kDa and light chain of 27 kDa size. The IgY was instable against olive flounders digestive factors and artificially modulated pH 2 and 3. Nevertheless, some activity of IgY appeared in intestine. IgY was orally administered with viable E. tarda to the olive flounders and the efficacy of protection against E. tarda infection was evaluated. Orally administered IgY at a dose of 20 mg/fish delayed infection period of E. tarda cannulated at $10^{6{\sim}8}CFU/fish$ to small size (30~40 g) and middle size (110~120 g) flounder. Moreover, orally administered IgY at dose of 20 mg/fish inhibited the penetration of E. tarda cannulated at $10^8CFU/fish$ into the liver, kidney, spleen and gill via intestine. The fish orally administered with IgY showed increased survival rate. These results suggest that egg yolk containing anti-E. tarda IgY is effective in preventing edwardsiellosis.

Purpose: This study investigated the effect of electroacupuncture stimulation on changes in blood biochemistry in spinal cord injury (SCI) rats whose cords were damaged by 6-hydroxydopamine (6-OHDA). Methods: Twenty-one Sprague-Dawley adult male rats were assigned to one of three groups: normal (n=7), control (n=7) and experimental group (n=7). The experimental group received electroacupuncture (Es-160, ITO, Japan) for 15 minutes in the form of low frequency (2 Hz) stimulation to the zusanli point. After treatment, we observed motor behavior recovery using the inclined plane test. We also measured serum and CNS concentrations and activities of enzymes including creatine kinase (CK), alkaline phosphatase (ALP), and Immunoglobulin G (IgG). Statistical analysis was done using one-way analysis of variance (ANOVA). Results: Concentrations of CK, ALP and IgG were lower in the experimental group than in the control group. Functional recovery was evaluated by the maximal angle of the inclined board on which rats could maintain their initial position. This allowed us to monitor progressive locomotor recovery. The maximal angles of the inclined plane test were higher in the experimental group than in the control group (p<0.05). Conclusion: The results of this study showed that electroacupuncture to the zusanli point has a therapeutic effect on functional recovery after SCI.

To construct a novel vaccine candidate against bovine enterotoxigenic Escherichia coli (ETEC), FanC, the major subunit of K99 fimbriae adhesion, was inserted into secretion plasmid pYA3560 containing a ${\beta}-lactamase$ secretion system. This was then transformed into ${\Delta}asd$ ${\Delta}crp$ Salmonella (S.) Typhimurium and designated as JOL950. Secretion of recombinant fanC fimbrial antigens was confirmed by immunoblot analysis. Groups of mice were inoculated with single or double doses of JOL950. Another group was used as a negative control. Compared to control mice, all immunized mice had significantly higher levels (p < 0.05) of serum immunoglobulin (Ig)G, and secretory IgA against FanC. The IgG2a and IgG1 titer assays revealed that immunization highly induced IgG2a compared to that of IgG1, indicating that T helper-1- related cell-mediated immune responses may be elicited by JOL950. The results show that both systemic and mucosal immunities against selected fimbrial antigens of bovine ETEC expressed by a live attenuated S. Typhimurium strain are prominently produced in mice immunized with JOL950 via an oral route.

A han transfers her serum immunoglobulin G to the agg (IgY) and gives immunity to her offspring. Therefore, The hen agg can be an effective supplier of a large amount of antigen specific antibody that accumulates in the egg yolk. Antigen specific antibody has been widely used for immunological analysis in the field of diagnosis as well as pure scientific research. The production and separation technology of IgY is demonstrated in the present study.
