This study was conducted to determine the possible use of Red Ginseng marc as stress inhibiter in thermal stress (temperature humidity index 86) and lipopolysaccharide (LPS) - exposed laying hens by investigating their effects on laying performance, blood biochemical parameters, immunoglobulin concentration and serum superoxide dismutase (SOD) like ability. A total of forty-five 52-wk-old laying hens (ISA Brown) were divided into 3 treatment groups with 5 replicates of 3 birds in each group. NC (negative control, no immune substances), PC (positive control, ${\beta}$-glucan 25 ppm) and RGM (Red Ginseng Marc 3%) were added in feed with respective substance. Egg production in RGM was significantly increased in comparison with NC groups for 8 weeks (P<0.05). On blood biochemical parameters, effects of ambient temperature is definite by showing significant difference in aspartate aminotransferase and others (P<0.05), but RGM both before and after thermal stimulation have no significant difference in comparison with other groups. And for 3 weeks after thermal stimulation, laying performance was also not significantly different among treatments. Immunoglobulin M content and SOD like activities after challenge with LPS were higher in the RGM and PC than NC (P<0.05). In conclusion, although ineffective as inhibiter in thermal stress, dietary supplementation of Red Ginseng marc improved SOD like activity and immune system by regulating immunoglobulin content in laying hens. These findings have laid the foundation for future studies of immunomodulation in laying hens fed Red Ginseng Marc and of evaluation of heat stress inhibitor.

Purpose : Kawasaki disease is the most common cause of systemic vasculitis in children less than 5 years of age. Recent immunohistochemistry findings suggest that many vascular growth factors play a role in the formation of the coronary artery lesions. Active remodeling of the coronary artery lesions in Kawasaki disease continues in the form of intimal proliferation and neoangiogenesis for several years after the onset of the disease. Intravenous immunoglobulin(IVIG) and corticosteroid have been used in the treatment of Kawasaki disease but the exact mechanism is not clear. We have investigated that IVIG and corticosteroid inhibited vascular endothelial growth factor(VEGF)-induced tube formation of endothelial cells in vitro on Matrigel assay. Methods : Human umbilical vein endothelial cells(HUVECs) were cultured and seeded on Matrigel coated 24 well plates in medium with or without the following agents : VEGF, VEGF plus IVIG, VEGF plus VEGF antibody, VEGF plus methylprednisolone, VEGF, IVIG plus methylprednisolone for 18 hours. The total length of tube structures in each photograph was quantified. Results : IVIG significantly inhibited the proliferation of HUVECs. The inhibitory effect of IVIG was also reversible. In the meantime, VEGF induced the differentiation of HUVECs into capillary like structures on Matrigel, which was inhibited by VEGF antibody in a dose-dependent manner. Interestingly, IVIG and methylprednisolone inhibited VEGF-induced tube formation of HUVECs. IVIG was more effective in inhibition than methylprednisolone alone. Conclusion : We revealed that VEGF induced the differentiation of HUVECs and this effect was inhibited by IVIG and methylprednisolone.
Purpose : We wanted to determine the characteristics of patients with Kawasaki disease (KD) who were unresponsive to intravenous immunoglobulin (IVIG). Methods : The patients with KD were divided into two groups: the IVIG responsive group (25 cases) and the IVIG unresponsive group (14 cases). We analyzed various parameters before and after the administration of IVIG, including the complete blood cell count with the differential count (%), the erythrocyte segmentation rate (ESR), the C-reactive protein (CRP) level and the protein and lipid profiles. Results : The IVIG unresponsive group had a prolonged duration of fever and a higher incidence of CAL compared to the IVIG responsive group (P<0.001, respectively). Before IVIG infusion, the neutrophil differential, the ESR and the CRP values were higher (P<0.001), and the total protein and albumin values were lower in the IVIG unresponsive group (P=0.01) compared to the IVIG responsive group. After IVIG infusion, there were no significant changes in the WBC count and CRP levels in the IVIG unresponsive group. The reduction of the HDL-cholesterol levels by IVIG was more significant in the unresponsive group (P=0.02). Conclusion : A more severe and prolonged inflammatory response occurred in the IVIG unresponsive group at an early stage, and this finding can be detected by such inflammatory parameters as the neutrophil count and the CRP and HDL-cholesterol levels after IVIG infusion.

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.
Purpose : Although intravenous immunoglobulin (IVIG) treatment is an effective first-line treatment for Kawasaki disease, 10-20% of the patients develop persistent fever or coronary artery complications. Medical records of Kawasaki disease patients were reviewed to assess the characteristic laboratory findings of IVIG nonresponsiveness. Methods : We reviewed the clinical records of 118 children with Kawasaki disease who were treated at the Chonnam National University Hospital from March 2003 to February 2008. The laboratory findings of the IVIG-responder group (n=110) and the IVIG-nonresponder group (n=8) were compared at admission day and at 48 hours and 14 days after IVIG administration. Results : At admission, the level of creatine kinase (CK) was lower (P =0.03) and that of total protein was higher (P <0.01) in the nonresponders than in the responders. At 48 hours after IVIG administration, the white blood cell (WBC) count (P =0.04) and neutrophil% (P <0.01) was higher in the nonresponders than in the responders. The neutrophil% (P <0.01) and CK (P =0.01) level at admission was lower than that at 48 hours after IVIG administration in the responders; this decrease was not as apparent in the nonresponders. Conclusion : IVIG nonresponders have lower CK and higher total protein levels at admission and higher WBC count and neutrophil% at 48 hours after IVIG administration. The decrease in the neutrophil% and CK level between at admission and at 48 hours after IVIG administration is remarkably higher in responders than in nonresponders.

Purpose : To determine the differences in clinical characteristics, blood chemistry and coronary artery complications between patients with Kawasaki disease who received intravenous immunoglobulin (IVIG) within the fourth day of illness and after the fifth day of illness. Methods : A retrospective chart review was conducted of all children with Kawasaki disease who were admitted to Ewha Mokdong Hospital between January 2001 and June 2002. The early treatment group received IVIG within the fourth day of illness(n=34) and the control group received IVIG after the fifth day of illness(n=53). Clinical manifestations, fever duration, hospitalization days, CBC, blood chemistry and coronary artery complications were compared between two groups. Results : No demographic differences were noted between the two groups(P>0.05). Total duration of fever was significantly shorter in the early treatment group than the control group($4.8{\pm}2.5days$ vs $7.4{\pm}3.0days$, P<0.05), but there were no differences in fever duration after IVIG treatment and hospitalization days between two groups(P>0.05). No significant differences were noted in the level of hemoglobin, WBC, ESR, CRP, AST, ALT and albumin between two groups(P>0.05). No significant differences in the incidence of IVIG retreatment were noted between the two groups(11.8% vs 5.7%, P>0.05). No significant differences in the incidence of coronary artery complications were noted between the two groups(11.7% vs 18.9%, P>0.05). No significant differences in the recurrence rate were noted between the two groups(3% vs 2%, P>0.05). Conclusion : Early IVIG treatment in patients with Kawasaki disease reduces the total fever duration. Coronary artery complications were not increased in patients with early IVIG treatment.
This trial was carried out to determine effects of TMR(Total Mixed Ration) in comparison to conventional diet on feed intake, digestibility, and nitrogen retention in Korean black goats. Twelve Korean black goats were allotted to treatments in four groups of three goats and the they were housed in separate metabolism cages for 21 days. Treatments included conventional diet(A: rice straw and commercial concentrates) as a control group and three TMR groups(B: rice straw and commercial TMR; C: 30% organic whole barley silage and rice straw with organic grain; D: 60% organic whole barley silage with organic grain). The results obtained are summarized as follows. Dry matter intake, fecal excreta, digestible dry matter, metabolic intake and feed intake of BW were significantly higher(p<0.05) compared with A, B, C treatment. The digestibility for most of nutrients except NFC was significantly higher(p<0.05) for D treatment than the others. On the other hand, the digestibility of NFC was higher for B treatment than for the others, even if it was not significantly different across treatments. Nitrogen intake was lower for D treatment, but the significant differences were not found across treatments. N retention rate was higher for B treatment with significant difference. For the blood composition, HDL cholesterol and Immunoglobulin G were significantly higher(p<0.05) for C, D treatment than the others. The results showed that, in comparison with A treatment(conventional diet) and B treatment(commercial TMR), dry matter intake, nutrient digestibility and N retention rate were not lower in C treatment(30% organic whole barley silage) and HDL cholesterol was increased after experiment. Therefore, it could be concluded that TMR with organic whole barley silage might contribute to the production of a high quality and safer meat in goat production.
In order to evaluate the significance of thyrotropin-binding inhibiting immunoglobulin (TBII) in the patients with autoimmune thyroid diseases, the authors investigated 402 cases of Graves' disease and 230 cases of Hashimoto's thyroiditis comparing 30 cases of normal healthy adult at Kyung Pook University Hospital from February 1993 to August 1994. The TBII was tested by radioimmunoassay and assesed on the dynamic change with the disease course, thyroid functional parameters, and other thyroid autoantibodies : antithyroglobulin antibody (ATAb) and antimicrosomal antibody (AMAb) including thyroglobulin. The serum level of TBII was $40.82{\pm}21.651(mean{\pm}SD)%$ in hyperthyroid Graves' disease and $8.89{\pm}14.522%$ in Hashimoto's thyroiditis and both were significant different from normal control of which was $3.21{\pm}2.571%$. The frequency of abnormally increased TBII level was 92.2% in hyperthyroid Graves' disease, 46.7% in euthyroid Graves' disease or remission state of hyperthyroidism, and 23.9% in Hashimoto's thyroiditis. The serum levels of increased TBII in Graves' disease were positively correlated with RAIU, serum T3, T4, and FT4, but negatively correlated with serum TSH(each P<0.001). The TBII in Graves' disease had significant positive correlation with serum thyroglobulin and AMAb, but no significant correlation with ATAb. In the Hashimoto's thyroiditis, the serum levels of TBII were positively correlated with RAIU, serum T3, TSH and AMAb, but not significantly correlated with serum T4, FT4, thyroglobulin and ATAb. Therefore serum level of TBII seemed to be a useful mean of assessing the degree of hyperthyroidism in Graves' disease and correlated well with thyroidal stimulation. The serum level of TBII in Hashimoto's thyroiditis is meaningful for the degree of both functional abnormality reflecting either hyperfunction or hypofunction and the immune logic abnormality.

Purpose: To investigate the clinicopathologic effects of cyclosporine A (CsA) in children with diseases characterized by mesangial immunoglobulin A deposits such as immunoglobulin A nephropathy (IgAN) and Henoch-Sch$\ddot{o}$nlein purpura nephritis (HSPN). Methods: We retrospectively reviewed the clinicopathologic outcomes of 54 children (IgAN, 36; HSPN, 18) treated with CsA. The starting dose of CsA was 5 mg/kg per day, and it was administered in 2 divided doses. The degree of proteinuria and pathologic changes in renal biopsies were evaluated before and after CsA treatment. Results: The mean protein to creatinine ratio decreased from $3.7{\pm}1.5$ to $0.6{\pm}0.4$(P <0.001), and 32 (59.2%) children achieved complete remission of proteinuria after 1-year CsA treatment. Among the 54 children, 24 maintained normal renal function and 25 exhibited microscopic hematuria or proteinuria at the end of CsA treatment. In the HSPN group, 3 children whose initial biopsies indicated class IIIb disease showed class II disease on follow-up, and the follow-up biopsies of 2 children who had class II disease indicated the same class II disease. In the IgAN group, cortical tubular atrophy occurred in 1 child, and no child with IgAN had cortical interstitial fibrosis or tubular atrophy after 1-year CsA treatment. No significant complications were found in the children treated with CsA. Conclusion: Our findings indicate that CsA treatment is effective and beneficial in reducing massive proteinuria and preventing progression to end-stage renal failure in children with glomerular diseases characterized by IgA deposits, such as IgAN and HSPN, within 1 year of treatment.
The direct wet mount examination of vaginal. secretion, widely applied for the diagnosis of Trichcmonas vaginalis infection in woman patients, is rapi4 and economical, however, the sensitivity of this technique is not so high. In this study enzyme-linked immunosorbent assay (ELISA) was employed for the detection of serum anti-T. vaginalis IgG and IsM antibodies from 30 vaginal trichomoniasis patients and 30 non-infected healthy persons. The results were as follows: 1. Serum ELISA-IgG value was $0.37{\pm}0.134(Mean{\pm}S.D.)$ in vaginal trichomoniasis patients and $0.21{\pm}0.054$ in healthy controls(P<0.005), and the sensitivity and specificity of ELISA for serum IgG antibody were 70.0% and 96.7%, respectively. 2. Serum ELISA-IgM value was $0.33{\pm}0.177 (Mean{\pm}S.D.)$ in vaginal trichomonlasls patients and $0.11{\pm}0.051$ in healthy controls (p<0.005), and the sensitivity and specificity of ELISA for serum IsM antibody were 70.0% and 96.7%, respectively. 3, The ELISA-IgG values showed a significant correlation with ELISA-IgM values(r=0.77, p<0.005) , With above results, it is assumed that ELISA is a reliable method for the diagnosis of T vaginalis infection and simultaneous measurement of serum IgG and IgM with this technique is recommended.
