[Study of the effects of free radicals produced by ultraviolet rays on viscosity of human synovial fluid. Methodological details].
After having pointed out a method measurement of the synovial Fluid (S.F.) viscosity by means of a white blood cell diluting pipette, obtaining results similar to those of Ostwald's viscometer, the AA have studied the osteoarthrotic S.F. viscosity after Ultra Violet Illumination. The production of Free Radicals induced by U.V., determines a fall of osteoarthrotic S.F. viscosity towards the values found in arthritic S.F..So, the AA, indirectly, confirme the capacity of Free Radicals to induce a S.F. viscosity modification like that provoked by the phlogistic process.
