  • Objective: This study was conducted to investigate whether acupuncture and moxibustion treatment could improve proteinuria in immunoglobulin A nephropathy. Methods: A 25-year-old man diagnosed with immunoglobulin A nephropathy had severely increased proteinuria. We conducted acupuncture treatment and moxibustion treatment on the abdominal area between the abdominal aorta and kidney at level L2. Results: After five months of acupuncture and moxibustion treatment, the patient's urine albumin/creatinine ratio and urine protein/creatinine ratio had improved from 0.571 to 0.28 and 0.79 to 0.47, respectively. Conclusions: This case report suggests that acupuncture and moxibustion treatment may ameliorate proteinuria in immunoglobulin A nephropathy.

  • Purpose: Perinatal cytomegalovirus (CMV) infection can lead to biliary atresia (BA) in different entities. This study aimed to compare the clinical, hematological, biochemical, and histological features of infants with BA based on their CMV immunoglobulin M (IgM) status at presentation. Methods: This cross-sectional descriptive study was carried out between January 2019 and June 2020 at the Department of Pediatric Gastroenterology and Nutrition at the Bangabandhu Sheikh Mujib Medical University (BSMMU) in Dhaka. Forty-three patients with BA were selected purposively and categorized into either the CMV IgM-positive or CMV IgM-negative BA group. Categorical variables were compared using Fisher's exact test and chi-square tests, while the Student's t-test and Mann-Whitney U-test were used to compare continuous variables. For all statistical tests, a p-value <0.05 was considered statistically significant. Results: Thirty-three (76.7%) of the cases were between 2 and 3 months of age on admission. The clinical, hematological, and biochemical parameters did not differ significantly between the CMV IgM-positive and CMV IgM-negative BA groups. Most (50.0%) of the CMV IgM-positive cases had fibrosis stage F2, while 43.5% of the CMV IgM-negative cases had fibrosis stage F3, with no significant difference between the groups (p=0.391). Conclusion: Our data shows no significant distinction between CMV IgM-positive and CMV IgM-negative BA, suggesting that CMV does not contribute to BA pathogenesis.

  • Background: B-1 cells differ from conventional B-2 cells both phenotypically and functionally. The aim of this study was to investigate the difference between peritoneal B-1 cells and splenic B-2 cells in proliferation. Methods: We obtained sorted B-1 cells from peritoneal fluid and B-2 cells from spleens of mice. During the culture of these cells, immunoglobulin secreted into the culture supernatants was evaluated by enzymelinked immunosorbent assay. Entering of S phase in response to LPS-stimuli was measured by proliferative assay. Results: Spontaneous Immunoglobulin M production occurred in peritoneal B-1 cells but not in splenic B-2 cells. LPS stimulated peritoneal B-1 cells secreted IgM at day 1, but splenic B-2 cells at day 2. In thymidine incorporation, peritoneal B-1 cells entered actively S phase after 24hours LPS-stimulation but splenic B-2 cells entered actively S phase after 48 hours. Conclusion: IgM secretion and S phase entering occurred early in peritoneal B-1 cells compared to splenic B-2 cells.

  • Immunoglobulin G was purified by 40% $(NH_4)_2SO_4$ precipitation, DEAE-Sephadex, Sephadex G-150 column chromatographies from rabbit antiserum against V. vulnificus ATCC 27562 O antigen and used for immunological test for V. vulnificus isolates. The profiles of cell lysate total protein and outer membrane protein from the isolates were analyzed by SDS-PAGE and densitometry. The overall profiles in all isolates were similar. Distict protein band was observed in comparison with V. parahaemolyticus. Western Blotting with rabbit Immunoglobulin G against cell lysates and OMP of V. vulnificus isolates showed a strong antigenic response to antigen 66, 60, 54, 48, 33 and 26 kDa which were common to all strains examined. The 26 kDa antigen showed V. vulnificus specific antigen in comparison with Vibrio parahaemolyticus. A sandwich enzyme-linked immunosorbent assay was developed by using rat anti-V. vulnificus ATCC 27562 polyclonal antibodies as capture antibody, a purified rabbit IgG antibody as detector antibody, and goat anti-rabbit IgG-alkaline phosphatase conjugate as developer antibody. When four V. vulnificus isolates were tested, the reactivity showed from 50 to 70% by sandwich ELISA.

  • Kimura's disease is an angiolymphoid-proliferative disorder that manifests with benign subcutaneous swelling predominantly in the head and the neck. Kidney involvement, including proteinuria, occurs in 12-16% of patients with the disease, and 60-78% of such cases is nephrotic syndrome. Reported etiologies of nephrotic syndrome in Kimura's disease include membranous glomerulonephritis, mesangial proliferative glomerulonephritis, minimal-change disease, focal segmental glomerulosclerosis, diffuse proliferative glomerulonephritis and immunoglobulin A (IgA) nephropathy. There have been only two case reports of IgA nephropathy in Kimura's disease, in 1998. In this report, we present a third case of IgA nephropathy associated with Kimura's disease.

  • The 'Dielectrophoretic Tweezers(DEP Tweezers)' can be used as a facile, economical toolkit for quantitative measurement of chemical and biological binding forces related to many biological interactions within a microfluidic device. Our experimental setup can probe the interaction between a single receptor molecule and its specific ligand. Immunoglobulin G(IgG) functionalized on polystyrene microspheres has been used to detect individual surface linked Staphylococcus protein A(SpA) molecules and to characterize the strength of the noncovalent IgG-SpA bond. It was measured and compared with the existing measurements. Measured single binding force of between Goat, Rabbit IgG and SpA were $17{\pm}7pN$, $74{\pm}16pN$. This work can be used to investigate several different ligand-receptor interactions and antigen-antibody interactions.

  • Purpose: It has been reported that 10% to 20% of children with Kawasaki disease (KD) will not respond to intravenous immunoglobulin (IVIG) treatment. In this study, we aimed to identify useful predictors of therapeutic failure in children with KD. Methods: We examined 309 children diagnosed with KD at the Kyungpook National University Hospital and the Inje University Busan Paik Hospital between January 2005 and June 2011. We retrospectively reviewed their medical records and analyzed multiple parameters in responders and nonresponders to IVIG. Results: Among the 309 children, 30 (9.7%) did not respond to IVIG. They had significantly higher proportion of neutrophils, and higher levels of aspartate aminotransferase, alanine aminotransferase (ALT), total bilirubin, and N-terminal fragment of B-type natriuretic peptide than did responders. IVIG-nonresponders had a significantly longer duration of hospitalization, and more frequently experienced coronary artery lesion, and sterile pyuria. No differences in the duration of fever at initial treatment or, clinical features were noted. Conclusion: Two independent predictors (ALT${\geq}$84 IU/L, total bilirubin${\geq}$0.9 mg/dL) for nonresponse were confirmed through multivariate logistic regression analysis. Thus elevated ALT and total bilirubin levels might be useful in predicting nonresponse to IVIG therapy in children with KD.

  • Effects of feeding seven strains of Lactobacillus spp. on the level of cell glutathione sulphydryl (GSH) in spleen, liver and erythrocyte of the ICR mice and on the level of immunoglobulin M in the spleen were determined. The level of cell glutathione sulphydryl in the spleen was dependent on the strain of Lactobacilli, it was significantly higher in the mice fed with L. casei CU 001, L. rhamnosus CU 02, L. acidophilus NCFM and L. casei YIT9018 (p>0.05). The level of cell glutathione sulphydryl in the liver increased in the mice fed with L. casei YIT9018, L. acidophilus NCFM, L. casei CU 001 (p>0.05), the level of glutathione sulphydryl of the erythrocyte showed significantly higher value than control mice when fed with L. acidophilus NCFM, L. casei YIT9018, L. casei CU 001 (p>0.05). The level of immunoglobulin M in the spleen of ICR mice expressed as the plaque count revealed significantly higher value than the control mice when fed with L. casei CU 001, L. acidophilus NCFM and L.casei YIT 9018.

  • The quality of an intravenous immunoglobulin preparation (IVIG) is reflected by the degree of nonspecific activation of complements, the so-called anticomplementary activity (ACA). ACA of aggregates in IVIG was investigated using method by the European Pharmacopoeia and Clq-coated microtiter enzyme-linked immunosorbent assay (ELISA). Both the EP method and the ELISA method showed a dose response curve with the amount of complements bound increasing with the percentage content of aggregates in immunoglobulin standard. The correlation between the two tests was good (r=0.96, r=0.99). However, the correlation was not found when the ACA (EP method) of IVIG product was compared with its aggregate percentage. These results emphasize that the method of aggregate formation affects ACA and that estimation of the percentage distribution of aggregates by HPLC may not reflect ACA. In analysing WIG product for Clq binding activity test with the ELISA, the result by using Protein A-HRP correlated with aggregate percentage (r=0.84). But the correlation decreased (r=0.48) when the result used Protein A-AP(having poorer sensitivity than HRP) was compared with aggregate percentage. As a result, some variation between the two methods, due to differences in assay principles, is to be expected. However, ELISA technique has the advantage in that it is easier to perform, more precise and less subject to reagent variability, and is the more suitable screening method than HPLC analysis.
