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.

Hemolytic disease in a newborn that causes early jaundice is common. It is often due to the Rh (D) and ABO incompatibility, but rarely due to unexpected antibodies. Among these unexpected antibodies, the anti-$Di^a$Dia antibody rarely occurs. The anti-$Di^a$ antibody was observed in the serum and red-cell eluate of an infant, and in the serum of his mother. The frequency of the appearance of the $Di^a$ antigen in the Korean population is estimated to be 6.4-14.5%. This paper reports a case of hemolytic disease in a newborn associated with the anti-$Di^a$ antibody. A full-term male infant was transferred to the authors' hospital due to hyperbilirubinemia the day after his birth. The laboratory data indicated a hemoglobin value of 11.6 g/dL, a reticulocyte count of 10.6%, a total bilirubin count of 14.4 mg/dL, a direct bilirubin count of 0.6 mg/dL, and a positive result in the direct Coombs' test. Due to the identification of an irregular antibody from the maternal serum, an anti-$Di^a$ antibody was detected, which was also found in the eluate made from the infant's blood. The infant had been treated with phototherapy and intravenous immunoglobulin since the second day after his birth and was discharged due to an improved condition without exchange transfusion. Therefore, in cases of iso-immune hemolytic disease in a newborn within 24 hours from birth who had a negative result in an antibody screening test, the conduct of an anti-$Di^a$ antibody identification test is recommended due to the suspicion of an anti-$Di^a$ antigen, followed by early administration of intravenous immunoglobulin.

This study was conducted to investigate the effects of dietary resveratrol on growth performance, blood biochemical parameters, immunoglobulin, and blood antioxidant activity in broiler chicks. Three hundred twenty one-day old broiler chicks were divided 8 treatments (C(-), basal diet; C(+), basal diet with antibiotics; DL-${\alpha}$-tocopherol 20 IU; DL-${\alpha}$-tocopherol 200 IU; resveratrol 20 ppm; resveratrol 200 ppm; methylated resveratrol 20 ppm; methylated resveratrol 200 ppm) with 4 replicates and 10 birds per replicate. Birds were reared for 35 days, and, at the age of 35 days, eight birds of average weight from each replicate were selected for blood samples collection. There were no significant differences on feed intake and feed conversion ratio. But final body weight and weight gain in antibiotics, resveratrol and methylated resveratrol treatments were significantly higher than no-antibiotics and ${\alpha}$-tocopherol treatments (P<0.05). There were no significant differences on carcass rate and relative organ weights among treatments, however, weights of liver and bursa of februcius in antibiotics, resveratrol and methylated resveratrol treatment were lower than other treatments. Weight of pancreas was high in resveratrol and methylated treatment. On the cecal microflora (total microbes, Coliform bacteria, Salmonella spp., and lactic acid bacteria), these in resveratrol and methylated resveratrol treatments didn't show the differences compared with those in no-antibiotics, antibiotics, and ${\alpha}$-tocopherol treatments. In the serum, there were no significant differences on creatinine, blood urea nitrogen (BUN), total protein, albumin, globulin, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) among treatments, though globulin contents of reseveratrol 200 ppm and methylated resveratrol 20 ppm treatments decreased compared to those of other treatments. Immunoglobulin (IgA, IgG and IgM) were significantly decreased in antibiotics and resveratrol treatments compared to that of no-antibiotics and ${\alpha}$-tocopherol treatments (P<0.05). Superoxide dismutase (SOD) like activity tended to increase in resveratrol groups (P<0.05), however, there was no significant difference on malondiakdehyde (MDA) content among treatments. In conclusion, these results showed that resveratrol derived from mulberry can be used as alternative of antibiotics through improvement of broiler's performance and maintain of health.

We used electrospary ionization ion trap tandem mass spectrometry (ESI-IT tandem MS) to structural elucidation of three different biantennary-type glycans having zero, one, two galactoses (G0, G1, G2). The highest fragment ion in the MS/MS spectra of three glycans was produced by 0,2-ring cleavage of fucose-linked N-acetylglucosamine (GlcNAc) in reducing end. The fragment ions both from precursor ions and 0,2-ring cleaved ions ($^{0.2}An$; n=5 for G0, n=6 for G1 and G2) were not overlapped each other. As results of $MS^n$ analyses, tandem fragmentation trees of each glycans were generated and 2,4-ring cleavages ($^{2.4}A_6$) were occurred in GlcNAc linked to reducing end GlcNAc. This structural elucidation and fragmentation study of N-linked glycans by tandem mass spectrometry can be applied to structural analysis of more complicated glycans.

Objectives : This study was designed to investigate the effects of alcoholic fermentation beverage using pear, Bae Ro Mi In (BRMI) on airway hyperresponsiveness and immunoglobulin production in asthmatic mice Methods : We investigated the effects of BRMI on airway hyperresponsiveness by measurement of enhanced pause (Penh), and also investigated the effects on production levels of antigen specific antibody and subclasses such as IgG1, IgG2a and IgE by using ELISA methods. Prednisolone (PD, 5 mg/kg) was used as positive control. Results : Treatment with BRMI did not lowered airway hyperresponsiveness, but PD lowered significantly. Oral administration of BRMI lowered production level of ovalbumin (OVA) specific total antibody significantly. Especially, BRMI decreased IgE levels compared to non-treated control effectively. Treatment with PD lowered production levels of total antibody, IgG1 and IgE. Conclusions : These result suggest that BRMI can lower production levels of antigen specific total antibody and IgE in asthmatic mice. We also suggest that BRMI has the possibility to prevent or cure asthma through regulation of antigen specific antibody production.

Purpose : $Henoch-Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis involving small vessels of skin, gastrointestinal(GI) tract and kidney. Digestive involvement of HSP can be serious with massive GI bleeding, perforation, and intussusception. However, some patients do not respond to conventional corticosteroid therapy. In this study, we investigated the efficacy of intravenous immunoglobulin (IVIG) for serious digestive manifestations not responding to steroid. Methods : From April 1999 to January 2005, 22 children diagnosed as HSP with severe GI symptoms were included. Initially, all patients were treated with intravenous methylprednisolone. IVIG 2 g/kg of body weight was infused in children refractory to steroid therapy. Clinical data were reviewed retrospectively. Results : Among 22 children, 12 children underwent IVIG therapy. The mean duration of corticosteroid therapy was $5.61{\pm}4.9$ days before IVIG therapy, and 11 of 12 patients experienced disappearance of GI manifestations after the initiation of IVIG infusion. In one patient, IVIG was ineffective in relieving abdominal pain, but melena subsided. Comparison of the duration of hospitalization between IVIG group and corticosteroid group revealed no significant difference($12.8{\pm}7.6$ days vs. $13.2{\pm}7.8$ days, P=0.777). But, the total duration of abdominal pain decreased in IVIG group although the difference between two groups was not significant($8.8{\pm}8.1$ days vs. $14.8{\pm}16.9$ days, P=0.306). Among 10 children treated with steroid only, 2 children were operated for bowel perforation and intussusception. In contrast, there was no perforation in 12 children who underwent IVIG therapy. Conclusion : IVIG could be the alternative therapy to corticosteroids in children with severe digestive manifestations of HSP.

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.

This study was conducted to investigate the effects of dietary quercetin on growth performance, blood biochemical parameters, immunoglobulin, and blood antioxidant activity in broiler chickens. Three hundred twenty one-day old Ross broilers were divided 8 treatments (C(-), basal diet; C(+), basal diet with antibiotics; vitamin E 20 IU; vitamin E 200 IU; quercetin 20 ppm; quercetin 200 ppm; methoxylated quercetin 20 ppm; methoxylated quercetin 200 ppm) with 4 replicates and 10 birds per replicate. Birds were reared for 35 days and their feed intake and weight gain were measured weekly. At 35d, eight birds of average weight from each replicate were selected for blood collection and analysis. Weight gain of birds in the groups fed quercetin was higher when compare to NC but there was no significant difference. In the serum, creatinine, BUN and AST in quercetin groups significantly decreased compared to those of control (NC and PC) (P<0.05). The contents of IgA and IgM were significantly lower in quercetin groups than those of NC (P<0.05). SOD like activity and MDA content tended to decrease in quercetin groups, however, there was no significant difference among treatments. In conclusion, supplemental quercetin to poultry diet could be positive aspect on performance and blood metabolites. Optimum adding levels was more than 20 ppm.

The study was carried out to investigate the effects of by-products of herbal medicines on performance, enteric microflora and blood biochemical profiles and immunological parameters in broiler chicks. A total of ninety-six, 3-d-old birds were assigned to a basal diet (CON) or a basal diet supplemented with 0.15 % (HM1), 0.3% (HM2) or 0.5% (HM3) by-products of herbal medicines. There was a significantly (p<0.05) improved feed conversion ratio (FCR) in birds fed diet supplemented with 0.15% by-products of herbal medicines (HM1) compared with the control birds during starter period (3~21 days). However, no difference in body weight, feed intake, total gain and FCR among treatment groups was observed during the entire feeding period (3~35 days). The colony forming units (CFU) of E. coli and Lactobacilli in the digesta of ileo-cecum was not also affected by dietary treatment. Serum AST (aspartate aminotransferase) and glucose decreased (p<0.05) in birds fed diets supplemented with herbal medicines compared with those fed the basal diet. In particular, the birds fed diets supplemented with herbal medicines showed a significant (p<0.05) increase in blood mean corpuscular volume (MCV) level compared with the control birds. However, the most of blood biochemical and hematological parameters and immunoglobulins (IgG and IgA) were not affected by the dietary treatment. In conclusion, the low level of dietary herbal medicines showed beneficial effects on FCR during starter period and liver functions, suggesting that by-products of herbal medicines may be applicable as functional feed additives in birds.

Background : Induction of oral tolerance (OT) has been known to prevent allergic inflammation in acute asthma model within 4 weeks. However it is remained whether induction of OT may effectively prevent allergic inflammation in chronic asthma model over 4 weeks. We observed the effect of induction of OT on allergic inflammation and airway remodeling in chronic asthma model up to 8 weeks. Methods : 5-week-old female BALB/c mice divided into 4 groups-control group, asthma group, low dose OT group, and high dose OT group. To induce oral tolerance mice were fed ovalbumin (OVA) before sensitization with OVA and aluminum hydroxide-1 mg for 6 consecutive days in the low dose OT group and 25 mg once in the high dose OT group. Mice in the asthma group were fed phosphate buffered saline instead of OVA. After sensitization followed by repeated challenge with aerosolized 1% OVA during 6 weeks, enhanced pause (Penh), inflammatory cells, IL-13, and IFN-${\gamma}$ levels in bronchoalveolar lavage (BAL) fluids as well as OVA-specific IgE, IgG1, and IgG2a levels in serum were measured. In addition the degree of goblet cell hyperplasia and peribronchial fibrosis were observed from lung tissues by PAS and Masson's trichrome stain. Results : Both OT groups showed a significant decrease in Penh, inflammatory cells, IL-13, and IFN-${\gamma}$ levels in BAL fluids as well as OVA-specific IgE, IgG1, and IgG2a levels in serum compared with the asthma group (P<0.05). In addition, the degree of goblet cell hyperplasia and peribronchial fibrosis were significantly attenuated in both OT groups compared with the asthma group (P<0.01). Conclusion : These results suggest that induction of OT may effectively prevent allergic inflammation as well as airway remodeling even in chronic asthma model up to 8 weeks.
