  • Western immunoblot analysis of antigen of T sergenti merozoite revealed that the immunodominant proteins of this organism were characterized as the 18KD, 29KD, 34KD, 45KD and 105KD in Korea. The 34KD and 45KD among those immunodominant proteins of the parasite were isolated and their amino acid sequences from the $NH_2$-terminus were determined and synthesized. They respective polypeptides were cationized to enhance their antigenicity, fortified with Freund's adjuvant and tested for immunogenicity in rabbits and cattle. The results obtained were as follows; 1. Theileria sergenti merozoite antigen was shown in 120KD, 100KD, 66KD, 45KD, 34KD and 30KD in western immunoblot using serum of rabbits immunized with 34KD synthetic polypeptide and 70KD, 58KD, 55KD and 45KD using bovine serum. In western immunoblot, 45KD, 34KD and 30KD were recognized by immunized rabbits, and 50KD and 45KD by cattle sera immunized with 45KD synthetic polypeptide, respectively. 2. The ELISA utilizing the synthetic polypeptides demonstrated significant antibody response to the respective peptides. After the 2nd booster injection, an OD of 0.760(preimmunization 0.132) in rabbits and an OD of 0.645(preimmunization 0.488) to 34KD synthetic polypeptide in cattle were observed. In animals immunized with 45KD synthetic polypeptide, after the 2nd booster injection, an OD of 0.640(preimmunization 0.144) in rabbit, and an OD of 0.776 (preimmunization 0.477) in cattle were measured. 3. After the 2nd booster the reciprocal IFA titer was 1:64 in rabbits and 1:512 in cattle immunized with the 34KD synthetic polypeptide. The IFA titre was observed as 1:512 in rabbit and 1:1,024 in cattle in immunized with the 45KD synthetic polypeptide.

  • Purpose: Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome with many causes, including Kawasaki disease (KD). The purpose of this study was to identify the laboratory tests needed to easily differentiate KD with HLH from incomplete KD alone. Methods: We performed a retrospective study on patients diagnosed with incomplete KD and incomplete KD with HLH (HLH-KD) between January 2012 and March 2015. We compared 8 secondary HLH patients who were first diagnosed with incomplete KD with all 247 incomplete KD diagnosed patients during the study period. The complete blood count, erythrocyte sedimentation rate, platelet count, and serum total protein, albumin, triglyceride, C-reactive protein, N-terminal pro-brain natriuretic peptide (NT-proBNP), and ferritin levels were compared. Clinical characteristics and echocardiography findings were also compared between the 2 groups. Results: The total duration of fever was longer in the HLH-KD group than in the KD group. White blood cell and platelet counts were higher in the KD group. Alanine aminotransferase, ferritin, and coronary artery diameter were increased in the HLH-KD group compared with those in the KD group. The median of NT-proBNP was significantly higher in the HLH-KD group than in the KD group at 889.0 (interquartile range [IQR], 384.5-1792.0) pg/mL vs. 233.0 (IQR, 107.0-544.0) pg/mL. Conclusion: The NT-proBNP level may be helpful in distinguishing incomplete KD from KD with HLH. The NT-proBNP level should be determined in KD patients with prolonged fever, in addition to the white blood cell count, platelet count, and ferritin level, to evaluate secondary HLH.

  • Let $\mathbb{Z}^n$ be the Cartesian product of the set of integers $\mathbb{Z}$ and let ($\mathbb{Z}$, T) and ($\mathbb{Z}^n$, $T^n$) be the Khalimsky line topology on $\mathbb{Z}$ and the Khalimsky product topology on $\mathbb{Z}^n$, respectively. Then for a set $X\;{\subset}\;\mathbb{Z}^n$, consider the subspace (X, $T^n_X$) induced from ($\mathbb{Z}^n$, $T^n$). Considering a k-adjacency on (X, $T^n_X$), we call it a (computer topological) space with k-adjacency and use the notation (X, k, $T^n_X$) := $X_{n,k}$. In this paper we introduce the notions of KD-($k_0$, $k_1$)-homotopy equivalence and KD-k-deformation retract and investigate a classification of (computer topological) spaces $X_{n,k}$ in terms of a KD-($k_0$, $k_1$)-homotopy equivalence.

  • Plasma membrane from the fungal cells (Aspergillus phoenicis, Rhizopus acidus, Candida albicans) treated with sodium benzoate (S.B), potassium sorbate (P.S) and calcium propionate (C.P) during the cultivation were separated. The contents and patterns of plasma membrane proteins compared with those of the control. The growth of A. phoenicis was decreased by the average 64.0% in the S.B treatment. That of R. acidus was inhibited by the average 69.0% in the P.S treatment. Also, That of C. albicans was showed the deminution of the average 59.5% in the S.B treatment. The contents of protein involved in the plasma membrane of the each fungal cells were inhibited the average 41.0%, 41.7% and 59.5% in the S.B treatment, respectively. In case of A. phoenicis, the changes in the protein pattern involved in the plasma membraneshowed the aspect similar to the control on the 1st day and 2nd day of cultivation in the treatment group, but $116\;KD{\sim}97\;KD$ band almost disappeared in the 5th day of cultivation, and $45\;KD{\sim}29\;KD$ band was uncleared through the cultivation. In S.B treatment group R. acidus was showed the loss of $116\;KD{\sim}97\;KD$ band from the middle stage of cultivation and P.S, and C.P treatment group were started the loss at the early stage and completely lost at the 36 hours of cultivation. In C. albicans, $116\;KD{\sim}97\;KD$ band were started the loss at the early stage to compare with the control and $66\;KD{\sim}45\;KD$ band were dimmed at the 96 hours of cultivation. Especially, the C.P treatment group were perfectly lost at the 96 hours of cultivation.

  • Purpose: Human adenovirus infection mimics Kawasaki disease (KD) but can be detected in KD patients. The aim of this study was to determine the clinical differences between KD with adenovirus infection and only adenoviral infection and to identify biomarkers for prediction of adenovirus-positive KD from isolated adenoviral infection. Methods: A total of 147 patients with isolated adenovirus were identified by quantitative polymerase chain reaction. In addition, 11 patients having KD with adenovirus, who were treated with intravenous immunoglobulin therapy during the acute phase of KD were also evaluated. Results: Compared with the adenoviral infection group, the KD with adenovirus group was significantly associated with frequent lip and tongue changes, skin rash and changes in the extremities. In the laboratory parameters, higher C-reactive protein (CRP) level and presence of hypoalbuminemia and sterile pyuria were significantly associated with the KD group. In the multivariate analysis, lip and tongue changes (odds ratio [OR], 1.416; 95% confidence interval [CI], 1.151-1.741; P=0.001), high CRP level (OR, 1.039; 95% CI 1.743-1.454; P= 0.021) and sterile pyuria (OR 1.052; 95% CI 0.861-1.286; P=0.041) were the significant predictive factors of KD. In addition, the cutoff CRP level related to KD with adenoviral detection was 56 mg/L, with a sensitivity of 81.8% and a specificity of 75.9%. Conclusion: Lip and tongue changes, higher serum CRP level and sterile pyuria were significantly correlated with adenovirus-positive KD.

  • Purpose: The aims of this study were to compare serum procalcitonin (PCT) levels between febrile children with Kawasaki disease (KD) and those with bacterial or viral infections, and assess the clinical usefulness of PCT level in predicting KD. Methods: Serum PCT levels were examined in febrile pediatric patients admitted between August 2013 and August 2014. The patients were divided into 3 groups as follows: 49 with KD, 111 with viral infections, and 24 with bacterial infections. Results: The mean PCT level in the KD group was significantly lower than that in the bacterial infection group ($0.82{\pm}1.73ng/mL$ vs. $3.11{\pm}6.10ng/mL$, P=0.002) and insignificantly different from that in the viral infection group ($0.23{\pm}0.34ng/mL$, P=0.457). The mean erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level in the KD group were significantly higher than those in the viral and bacterial infection groups (P<0.001 and P<0.001 for ESR, P<0.001 and P=0.005 for CRP, respectively). The proportion of patients in the KD group with PCT levels of >1.0 ng/mL was significantly higher in the nonresponders to the initial intravenous immunoglobulin treatment than in the responders (36% vs. 8%, P=0.01). Conclusion: PCT levels may help to differentiate KD from bacterial infections. A combination of disease markers, including ESR, CRP, and PCT, may be useful for differentiating between KD and viral/bacterial infections.

  • Spirometru erinocei의 유충인 sparganum에서 추출한 조항원 단백질을 항원으로 하여 sparganosis, cysticercosis, hydatidosis환자의 IgG 항체와 정상인의 IgG 항체를 혈청반응시켜 ELISA와 EITB에 의해 교차반응을 일으키는 비 특이항원 성분과 종특이항원 성분을 추구하였다. 1. sparganum에서 0.01 M PBS (PH 7.4)로 추출한 조항원 단백질을 SDS-PAGE로 전개하여 290 Kd에서 23 Kd범위의 분자량을 가진 25개의 단백질이 분획되었다. 2. sparganum의 조항원을 항원으로하여 ELISA로 sparganosis, cysticercosis, hydatidosis 환자의 190 항체와의 혈청 반응치는 sparganosis환자에게서는 0.44 $\pm$ 0.07에서 1.90 $\pm$ 0.03으로 negative control normal sera의 0.D (0.15 $\pm$ 0.03)를 기준으로 하였을 때 모두 양성이며 민감도(sensitivity)가 100 %이었으며 cysticercosis, hydatidosis환자혈청에서 양성반응이 나타났으며 교차반응도 있었다. 3. EITB에서는 spargancsis환자의 IgG항체에 의해 16개의 항원성분이 인지되었으며 이 중 6개의 항원성분이 정상인의 혈청에서도 인지되어 교차반응을 일으키는 항원성분이었으며 cysticercosis환자혈청에서 인지된 4개의 항원성분 중 2개의 항원성분이 sparganosis 환자혈청에서 인지된 것과 같았으며 hydatidosis환자의 190항체에 의해 인지된 19개의 항원성분 중 12개의 항원성분이 sparganosis환자혈청에서 인지된 항원 성분과 같았다. 4. 290 Kd, 200 Kd, 28 Kd의 항원성분은 sparganosis환자의 196항체에서만 인지되었고 228 Kd, 152 Kd, 66 Kd항원성분은 hydatidosis환자의 19G항체에서만 인지되었으며 66 Kd항원성분은 sparganosis, cysticercosis, hydatidosis, 정상인의 혈청에서 모두 인지되었다. We studied the serological reaction between the specific and nonspecific antigenic components from metacestode (plerocercoid) of spiromeko erimacei and IgG antibodies in sparganosis, cysticercosis. hydatidosis patients and normal human sera by ELISA and EITB. We prepared the crude extracts of sparganlim from snake, Matrix tigrina laterolis and used as antigenic components. By SDS-PAGE, we detected a total 25 peptide bands (fractions) with 290 Kd to 23 Kd molecular weight, and 8 bands of these detected bands developed strongly by silver stain. In serological test, ELISA, we recognized the cross-reaction of antigenic components reacting with IgG antibodies in heterogenous sera, cysticercosis and hydatidosis patients sera. The crude antigenic components of sparganum showed the high sensitivity in sparganosis, hydatidosis patients sera, but showed lower sensitivity in cysticercosis patients sera than the sparasanosis, hydatidosis patients sera. Sixteen antigenic components of these 25 separated bands were recognized by antibodies In sparsanosis patients sera,8 antigenic components in normal human sera, 4 antigenic components in cysticercosis patients sera and 19 antigenic compoenents in hydatidosis patients sera. The crude antigenic compnenets with 290 Kd, 200 Kd, 125 Kd and 28 Kd molecular weight was only recognized in sparganosis patients sera, but 64 Kd antigenic component was nonspecific antigenic components which were also cross-reacted with sparganosis, hydatidosis, cysticercosis patients sera and normal human sera.

  • Electrophoretic studies of protein extracts from carrot calluses suspension-cultured on the media containing kinetin, BA, IAA, NAA or $GA_3$ at the levels of $10^{-6},\;10^{-5},\;10^{-4}M$, respectively, were performed to identify polypeptides and proteins regulated by auxin, cytokinin or GA. Fifteen bands of polypeptide(s) were observed in the callus cultured in the control medium devoid of growth regulators, and their molecular weights were $18._4,\;20._2,\;20._0,\;34._9,\;35._7,\;37._4,\;40._3,\;42._2,\;44._1,\;44._4,\;49._3,\;55._0,\;56._6,\;58._1,\;and\;59._9\;KD$, respectively. The synthesis of polypeptide appeared to be promoted in two bands by kinetin, in six bands by BA, in one band by IAA, in two bands by NAA, and in four bands by $GA_3$, while inhibited in five bands by kinetin, in three bands by BA, in four bands by IAA, in three bands by NAA and in three bands by $GA_3$. The polypeptides of $40._3\;KD\;42._2\;KD$ seemed to be regulated by cytokinins, and those of $44._1\;KD,37._4\;KD,\;and\;56._6\;KD$ by auxins. The proteins of three bands with relative mobilities of 0.56, 0.84, and 0.92, respectively, increased in the calluses cultured on the media containing kinetin, IAA, $GA_3$, NAA or BA, compared to the control, but it was difficult to identify the proteins specific for each growth regulator.

  • Purpose: This single-center study was conducted to assess the changes in epidemiological and clinical characteristics and outcomes of patients with Kawasaki disease (KD) over the past 7 years. Methods: This retrospective study included 135 children with KD, admitted to Chungnam National University Hospital, Daejeon, between 2004 and 2005 (group A, n=53) and between 2011 and 2012 (group B, n=82). Medical records were reviewed to obtain information regarding the presenting signs and symptoms, demographic characteristics, and laboratory and echocardiographic findings associated with KD. Results: The hospital admission date after onset was significantly earlier in group B than in group A (P=0.008). The proportion of patients with incomplete KD was 45.3% and 65.9% in group A and B, respectively (P=0.018). The number of pretreatment coronary artery lesions (CALs) were significantly lesser in group B than in group A. (10/53 vs. 5/82, P=0.021). No significant differences was observed in the incidence of CALs at discharge, febrile phase duration, hospital stay duration, incidence of retreatment, and intravenous immunoglobulin dose between 2 groups. The total febrile phase was shorter in patients with incomplete KD than in those with complete KD in both groups. Conclusion: The proportion of incomplete KD has become higher. Furthermore, early admission and management of patients with KD may be related to increased incomplete KD and decreased CALs. Therefore, we believe that a diagnostic strategy for incomplete KD should be established regardless of the presence of coronary lesions.
