Classification serological

It is an autoantibody whose autoantigen is the Fc portion of IgG. Rheumatoid factors may be of any immunoglobulin isotype but it is IgM rheumatoid factor that is commonly measured in rheumatoid arthritis. Classification criteria for rheumatoid arthritis include only one serological test, namely rheumatoid factor. However, it is not diagnostic test rather it may be confirmatory when a number of other clinical features are present. 

LPSs carry the major immunogenic determinants on the cell surface of Gram-negative bacteria and, in many instances, serve as the basis for their serological classification. In this section, contribution of LPSs that contain 5,7-diamino-3,5,7,9-tetradeoxynon-2-ulosonic acids to the immunospecificity and serological classification of two human pathogens, viz. L. pneumophila and P. aeruginosa, are reviewed. 

The descriptive phase of biology is an essential prerequisite for the healthy growth of biochemistry, and the serological classification of the Salmonellas and related Enterobacteria has allowed a comprehensive and reproducible series of analyses to be made where otherwise a chaotic situation could have arisen. The Kauffmann-White Schema embraces more than the specificities due to polysaccharides of the O antigens. The H antigens, for example, are specificities due to the protein components of the flagella, and these are probably beyond the scope of chemical methods available at this time. 

Initially, this classification, which was based on well-defined histological criteria, proved useful — espiedally since reliable serological or immunological differentiation was not possible at that time. It should be mentioned that the differentiation of CLH was, however, not generally accepted — although this condition is frequently seen in chronic hepatitis C. (12, 18, 24, 26) (s. tabs. 34.1)...

The location of these gly can molecules on the bacterial outer membrane makes them an important component in the pathogenesis of endotoxemia and septic shock syndromes, and in the survival and overall biological functions of the bacterium. Moreover, LPSs with differences in chemical stmctures of the 0-chains often provide a molecular basis for serological classifications within the same genus. " ... 

They can express any of the pancreatic hormones, as well as ectopic peptides. In some cases, there is more than one hormone expressed. If an IHC "hormone panel" is to be used, the six hormones cover the vast majority of the cases insulin, glucagon, somatostatin, PP, gastrin, and VIP however, hormone IHC in the tumor does not necessarily correlate with the "functionality" status in all cases. Discrepancies do occur, and therefore serology and symptomatology are more reliable in classification of "functionality" status. 

Systemic lupus erythematosus (SLE). A chronic, remitting-relapsing inflammatory autoimmune disease affecting multiple organ systems, such as the skin, joints, serosal membranes, kidneys, blood cells, and central nervous system. The disease is very heterogeneous in clinical expression and serological factors. Autoantibodies directed against nuclear components ( - antinuclear antibodies) are typically detected. Anti-dsDNA, anti-Sm, and antiphospholipid antibodies are used as classification criteria. 

The nomenclature of the HLA system is determined by the World Health Organization (WHO) Nomenclature Committee and reflects both the serological and the nucleotide levels of classification. The 1991 report of the Nomenclature Committee listed 27 HLA-A specificities, 59 HLA-B specificities, and 10 HLA-C specificities as shown in Table 1 (B17). These are the specificities that are detectable at the serological level. Contributing to some of these individual specificities, however, can be a large number of different alleles. At least 10 different alleles code for the specificity HLA-A2, for example, and 7 code for HLA-B27. To accommodate this complexity, the Nomenclature Committee has... 

Hegnauer published a chapter entitled Chemical Evidence for the Classification of Some Plant Taxa, one section of which he devoted to the plants of the Papaveraceae family. According to him, the classification of this family is still controversial. The chemistry of the constituents suggests that the family Papaveraceae is out of place in the order Rhoeadales. Hegnauer assumes that the chemistry and the serology will help to resolve this problem also in the species and genera of this family (831). The chemotaxonomy of the plants Papaveraceae, Ranunculaceae, and Berberi-daceae was also studied by Tetenyi and Vagujfalvi (832). 

It is well-known that C. albicans is one of the most important pathogenic fungi causing a serious infectious disease. Candidiasis, in humans. In order to provide a serological classification system for yeasts including genus Candida, antigen structure analyses of C. albicans and its closely related species have been conducted by several workers, Martin (17),...
