Immunoglobulins (IgA, IgG and IgM), complement (C3) and transferrin levels were measured by single radial immunodiffusion. The extent of glomerular injury was estimated by determining the selectivity of proteinuria. The relationship between the severity of glomerular damage and serum concentrations of immunoglobulins and complement was assessed. Higher IgM and lower IgG serum concentrations were found in nephrotic patients than in normal controls (157 +/- 108 mg+ vs 127 +/- 38 mg% for IgM, 929 +/- 537 mg% for IgG). The difference was statistically significant (p less than 0.05 for IgM, p less than 0.001 for IgG). No correlation was present between the selectivity of proteinuria and serum levels of IgA, IgM, IgG or C3. The results indicate that abnormalities in humoral components of the immune system are present in nephrotic patients and are probably related to a basic immunological defect in the patients rather than to the severity of glomerular damage.</p>","PeriodicalId":76873,"journal":{"name":"Zhonghua Minguo wei sheng wu xue za zhi = Chinese journal of microbiology","volume":"10 1-2","pages":"21-7"},"PeriodicalIF":0.0,"publicationDate":"1977-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11779819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationship between the production of HSV-1 inhibitors and the degree of Epstein-Barr virus (EBV) genome repression in lymphoblastoid cells were also examined. Among the cell lines used P3HR-1 and no.223 cells produced a few EBV particles, Raji and NC-37 cells contained EBV genomes only, and MOLT-4 as well as KB cells were EBV genome-negative. The results revealed that P3HR-1 cell extract showed a tendency to inhibit HSV-1 growth in GMK cells but the other 4 lymphoblastoid cell lines and KB cells did not produce HSV-1 inhibitors, indicating that EBV genomes governing the formation of EBV structural antigens were not related to the production of HSV-1 growth inhibitors.
