RESUMO
In several pathologic conditions of the joints, it is rather frequent to find a swollen joint. The authors performed an analysis of the joint fluid proteins from 20 cases of rheumatoid arthrit is and 20 normal Kore an adults with the object of evaluating the significance of it s clinical application. The study was done with Beckman Model R System, Durrum type cell, and scanned with Model RB Analytrol. Scheicher and Schuell 2043-A paper was used with diethyl barbituric acid-sodium diethyl barbituratebuffer, pH 8.6, ionic strenght 0.075 and stianed with 0.1% bromphenol blue. The results obtained were as follows: 1) The amount of total protein was significantly increased with average of 4.80 + 1.249gm% in comparison with 2.34 + 0.553gm% in normal group. 2) Albumin fraction showed the average of 41.86 + 6.219% in comparison with 64.85 + 5.288% in normal group. 3) Alpha 2 globulin fraction disclosed the average of 10.19 + 3.379% in comparison with 4.24 + 1.158% in normal group, which was significantly increased one. 4) Gammaglobulin fraction was also significantly elevated with the average of 21.51 + 8.942% in comparison with 11.70 + 1.923% in normal group. 5) There was noted a decreased A/G ratio, the average of 0.74 + 0.196, in comparison with 1.911 + 0.430 in normal group.
