  • Objectives : The aim of this study was to investigate the effect of Chunghwatang (CHT) for atopic dermatitis. Methods : CHT, a verified anti-oxidant and anti-inflammatory effect, was treated in atopic dermatitis animal model to investigate cytokine levels and immunoglobulin production. Results : Clinical skin index was 47.1%, suggesting significant efficacy of CHT in atopic dermatitis treatment. Serum IL-4, IL-6, IL-13, TNF-${\alpha}$ and histamine productions were significantly decreased to 52.3%, 61.8%, 68.0%, 37.4%, and 46.6%, respectively. The production of IL-5 was decreased to 33.3%. The increase of Immunoglobulin IgG1 production along with IgE through the interaction of IgE and IL-4 induced by IL-4 and IL-13 were measured as 20.7% and 23.4%, respectively. Conclusions : The results above, along with the in vitro test results, strongly supports the CHT samples as effective immunomodulator in AD treatments, suggesting its use in clinical practice and basic information for EBM.

  • This study was carried out to investigate the effect of dietary supplementation of red ginseng by-product (RGB) on the laying performance, blood biochemistry, and microbial population in laying hens. A total of 120 Hy-Line Brown laying hens (75 weeks old) were randomly allotted to 1 of 3 dietary treatments with 4 replicates per treatment. A commercial-type basal diet was prepared, and 2 additional diets were prepared by supplementing 5.0 or 10.0 g/kg of RGB to the basal diet at the expense of corn. The diets were fed to hens on an ad libitum basis for 4 weeks. There were no differences in feed intake, egg weight, and feed conversion ratio during 4 weeks of the feeding trial. However, hen-day egg production was significantly greater (p<0.05) for the RGB treatment groups than that for the basal treatment group. There were no differences in triglyceride, aspartate aminotransferase, and alanine aminotransferase during the 4-week feeding trial. However, RGB supplementation increased (p<0.05) the serum immunoglobulin G (IgG) and IgM content compared with basal treatment group. The total cholesterol was lower (p<0.05) in the RGB treatments groups than that in the basal treatment group. The intestinal Lactobacillus population was greater (p<0.05) for the RGB treatments groups than that for the basal treatment group. However, the numbers of Salmonella and Escherichia coli were not different among dietary treatments. During the entire experiment, there was no significant difference in egg quality among all the treatments. In conclusion, in addition to improving hen-day production, there were positive effects of dietary RGB supplementation on serum immunoglobulin and cholesterol levels in laying hens.

  • Immunoglobulin G4 (IgG4) related autoimmune diseases are characterized by high serum IgG4 concentrations, sclerosing inflammation of numerous IgG4-positive lymphoplasma cells of varying origin, and a positive response to steroid treatment. Autoimmune pancreatitis, sclerosing cholangitis, and retroperitoneal fibrosis are representative presentations of IgG4 related autoimmune disease. Herein, we describe 2 patients (40-years-old woman and 47-years-old man) diagnosed with pulmonary involvement of IgG4-related autoimmune disease. The patients were admitted for an evaluation of the lung mass or multiple lung nodules found on chest radiography. Surgical lung biopsies were performed and pathologic finding revealed lymphoplasmacytic sclerosing inflammation with numerous IgG4 positive cells. The patients had elevated serum total IgG and IgG4 levels. Treatment consisted of high dose methylpredinisolone (1 mg/kg/day) and demonstrated good responsiveness. However, one patient experienced 2 relapses while being tapered off of steroid treatment.

  • T cell immunoglobulin mucin domain (TIM)-3 is an immunomodulatory molecule and upregulated in T cells by several cytokines. TIM-3 also influences mast cell function but its transcriptional regulation in mast cells has not been clarified. Therefore, we examined the transcript level and the promoter activity of TIM-3 in mast cells. The TIM-3 transcript level was assessed by real-time RT-PCR and promoter activity by luciferase reporter assay. TIM-3 mRNA levels were increased in HMC-1, a human mast cell line by TGF-${\beta}1$ stimulation but not by stimulation with interferon (IFN)-${\alpha}$, IFN-${\lambda}$, TNF-${\alpha}$, or IL-10. TIM-3 promoter -349~+144 bp region relative to the transcription start site was crucial for the basal and TGF-${\beta}1$-induced TIM-3 promoter activities in HMC-1 cells. TIM-3 promoter activity was increased by over-expression of Smad2 and Smad4, downstream molecules of TGF-${\beta}1$ signaling. Our results localize TIM-3 promoter activity to the region spanning -349 to +144 bp in resting and TGF-${\beta}1$ stimulated mast cells.

  • Parvovirus B19(PV B19) is a nonenveloped single-stranded DNA virus that causes a wide variety of diseases ranging from benign childhood infection such as slapped-cheek rash(fifth disease) to life threatening diseases such as hydrous fetalis in fetuses or aplastic anemic crises in patients with hemolytic anemia. In immunocompromised hosts including organ transplant recipients, this infection can cause chronic anemia. Recently, the reports of cases of PV B19 infection have been increasing in transplant recipients and most reported cases of PV B19 infection-associated anemia in renal transplant recipients were successfully treated with intravenous immunoglobulin infusion. We experienced two cases of aplastic anemia caused by PV B19 infection in pediatric renal transplant recipients. The patients were an 8 year-old boy and 12-year-old boy who received allograft kidneys from their mothers. Anemia developed 2 weeks after transplantation and their serum was positive for PV B19 PCR. They were treated with 400 mg/kg of intravenous immunoglobulin(IVIG) for 5 consecutive days. In one of the case, anemia was corrected promptly after the first 5-day course of IVIG therapy but in the other, anemia persisted but responded to the second course of IVIG therapy. One year later, the patients have normal hematocrit levels and stable renal function These are the first cases of PV B19 infection treated successfully with IVIG in pediatric renal transplant recipients in Korea.

  • Purpose : Intravenous immunoglobulin(IVIG) has been used as an immunomodulatory treatment for several immune-mediated diseases. The early effect of high-dose IVIG on biochemical profiles including lipids and proteins was evaluated in patients with Kawasaki disease(KD). Methods : Twelve children with KD(nine boys) were treated with IVIG of 2 g/kg over 12 hours. Serial sera were collected from the patients four times : before IVIG treatment and two hours, 24 hours and seven days after IVIG treatment. The samples were frozen at $-20^{\circ}C$ before biochemical analysis. Results : A significant decrease in albumin concentration was found two hours h and 24 hours after IVIG treatment, but this recovered to the pretreatment level after seven days. Total cholesterol and triglyceride increased slightly after seven day. A significant decrease in HDL-cholesterol and C-reactive protein was seen two hours and 24 hours after IVIG treatment. Conclusion : High-dose IVIG affects immediate changes in protein profiles and HDL-cholesterol in KD. Changes in HDL-cholesterol induced by IVIG may be the result of changes in systemic protein metabolism.

  • The object of this trial was to investigate the effect of dietary ${\beta}$-1,3/1,6-glucan supplementation on the performance and immunological response of broiler chickens. Two hundred and forty 1-day old male broilers ($39{\pm}1g$) were separated into six treatments which were given six different feeds containing 0 (control), 25, 50, 75, 100 and 125 mg/kg dietary ${\beta}$-1,3/1,6-glucan supplementation. On days 21 and 42, body weight gain, feed consumption and feed conversation rate were recorded as measures of growth performance. The levels of key cytokines in the immuno-regulating pathway: interleukin-1 (IL-1), interleukin-2 (IL-2), interferon $\gamma$(IFN-$\gamma$, tumor necrosis factor $\alpha$(TNF-$\alpha$, and the concentrations of signal molecules: peripheral blood plasma globulin, serum Immunoglobulin G (IgG) and intestinal secretary Immunoglobulin A (sIgA), were measured as indices of the immune response to determine suitable levels of dietary ${\beta}$-1,3/1,6-glucan supplementation. The results indicated that performance was elevated quadratically with dietary ${\beta}$-1,3/1,6-glucan supplementation. Maximal growth performance and an enhanced immunological response were obtained at a supplemented level of 50 mg/kg.

  • Purpose: We conducted a study to determine which factors may be useful as predictive markers in identifying Kawasaki disease (KD) patients with a high risk of resistance to intravenous immunoglobulin (IVIG) and developing coronary artery lesions (CAL). Methods: We enrolled 287 patients in acute phase of KD at a single center. The demographic, clinical and laboratory data were collected retrospectively. Results: There were 34 patients in the IVIG resistant group. The IVIG resistant group had significantly higher serum N-terminal-pro-brain natriuretic protein (NT-proBNP) levels (P<0.01) and polymorphonuclear neutrophil (PMN) percentage (P<0.01) in comparison to the IVIG responders. The results yielded sensitivity (78.8%, 60.6%), specificity (58.2%, 90%) and cutoff value (628.6 pg/mL, 80.3%) of NT-proBNP and PMN respectively, in predicting IVIG resistance. Despite IVIG administration, 13 of the 287 patients developed CAL. The patients in the CAL group had higher NT-proBNP levels (P<0.01) and higher PMN percentage (P<0.01). In these patients, the results yielded sensitivity (73.3%, 56.7%), specificity (67.9%, 88.9%) and cutoff value (853.4 pg/mL, 80.3%) of NT-proBNP and PMN respectively, for predicting CAL. The area under the curve (AUC) for predicting resistance to IVIG was NT-proBNP 0.712, PMN 0.802. The AUC for predicting CAL was NT-proBNP 0.739, and PMN 0.773. Conclusion: Serum NT-proBNP levels and PMN percentage were significantly elevated in patients with KD with IVIG resistance and CAL. Thus, they may be useful predicting markers for IVIG resistance and development of CAL in KD patients.

  • Immunoglobulin G4 (IgG4)-related disease is a newly recognized condition characterized by fibroinflammatory lesions with dense lymphoplasmacytic infiltration, storiform-type fibrosis and obliterative phlebitis. The pathogenesis is not fully understood but multiple immune-mediated mechanisms are believed to contribute. This rare disease can involve various organs and pleural involvement is even rarer. We report a case of IgG4-related disease involving pleura. A 66-year-old man presented with cough and sputum production for a week. Chest radiography revealed consolidation and a pleural mass at right hemithorax. Treatment with antibiotics resolved the consolidation and respiratory symptoms disappeared, but the pleural mass was unchanged. Video-assisted thoracoscopic surgery was performed. Histopathology revealed dense lymphoplasmacytic infiltration and storiform fibrosis with numerous IgG4-bearing plasma cells. The serum IgG4 level was also elevated. Further examination ruled out the involvement of any other organ. The patient was discharged without further treatment and there is no evidence of recurrence to date.

  • We evaluated the clinical and laboratory characteristics of five children with Kawasaki disease who had showed arthritis after responding to intravenous immunoglobulin(IVIG) treatment. Age distribution was between 13 months and six years of age(mean $3.2{\pm}1.6$ years). There were two males and three females. Arthritis occurred when acute symptoms were subsiding, with the average onset on day $5.8{\pm}1.8$ after final IVIG treatment. Arthritis was pauciarticular in three, and polyarticular in two. Regarding laboratory findings, one child was positive in rhematoid factor and changed to negative after two months. Three patients were examined for HLA B27 and all showed negative results. High dose aspirin(two cases), anti-inflammatory drug(ibprofen, three cases), and corticosteroids(methyprednisolon pulse therapy, one case) were used for this type of arthritis. Symptoms and signs of arthritis in all patients were improved by these therapies. There was no relapse or complications within six months. Arthritis after responding to IVIG therapy was rarely observed in children with Kawasaki disease. This type of arthritis responded well to anti-inflammatory drugs including corticosteroids, and showed no relapses.
