N-terminal procollagen peptide and beta 2-microglobulin in synovial fluids from inflammatory and non-inflammatory joint diseases. 1984

A M Gressner, and H H Neu

The concentrations of NH2-terminal procollagen peptide were determined radioimmunologically in synovial fluids from inflammatory and non-inflammatory joint diseases. The mean concentrations +/- SD were 1.39 +/- 0.77 and 1.13 +/- 0.63 mg/l and, hence, did not reveal significant differences. Compared with serum, peptide levels in synovial fluids are 10(3) times higher. No statistical correlation was found between procollagen peptide levels and the concentrations of beta 2-microglobulin, a suggested parameter of disease activity, and other established indicators (total protein, total and differential cell count) of inflammatory activity.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.

D001172 Arthritis, Rheumatoid A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated. Rheumatoid Arthritis
D001613 beta 2-Microglobulin An 11-kDa protein associated with the outer membrane of many cells including LYMPHOCYTES. It is the small subunit of MHC CLASS I MOLECULES. Association with beta 2-microglobulin is generally required for the transport of class I heavy chains from the endoplasmic reticulum to the cell surface. Beta 2-microglobulin is present in small amounts in serum, CEREBROSPINAL FLUID, and urine of healthy individuals, and to a much greater degree in the urine and plasma of patients with tubular PROTEINURIA, renal failure, or kidney transplants.

D013582 Synovial Fluid The clear, viscous fluid secreted by the SYNOVIAL MEMBRANE. It contains mucin, albumin, fat, and mineral salts and serves to lubricate joints. Synovia,Fluid, Synovial,Fluids, Synovial,Synovial Fluids
