Synovial fluids from patients were examined, including 15 cases of rheumatoid arthritis (RA); 9 cases of sero-negative arthropathy (3 cases of ankylosing spondylitis, 6 cases of reactive arthritis); 1 case of gout arthritis; and 5 cases of osteoarthritis. The synovial fluids contained 330-72600 white blood cells/mm3, 9-97% of which were granulocytes, in RA patients. Other physical features of RA fluids were: straw green color, cloudy or unclear; moderate viscosity; fair or poor mucin clotting; lack of crystals and bacteria. Synthesis of the above may contribute to the diagnosis of RA. We also found that IgG, IgA and IgM of serum and IgG of synovial fluids in 15 cases of RA were higher than in the other arthritis groups; the IgM-RF positive rates of RA synovial fluids and sera were 20% and 35.7% respectively, while all were negative in the other groups. Immunoglobulins and complement levels in the synovial fluids of all the tested arthritis cases were about half of those in the serum.
对患者的滑液进行了检查，包括15例类风湿性关节炎（RA）患者；9例血清阴性关节病（3例强直性脊柱炎、6例反应性关节炎）患者；1例痛风性关节炎患者；以及5例骨关节炎患者。RA患者滑液中的白细胞计数为330 - 72600个/mm³，其中9% - 97%为粒细胞。RA滑液的其他物理特征为：草绿色、浑浊或不清；粘度适中；粘蛋白凝块一般或较差；无晶体和细菌。综合上述特征可能有助于RA的诊断。我们还发现，15例RA患者血清中的IgG、IgA和IgM以及滑液中的IgG均高于其他关节炎组；RA滑液和血清的IgM-RF阳性率分别为20%和35.7%，而其他组均为阴性。所有受试关节炎病例滑液中的免疫球蛋白和补体水平约为血清中的一半。
