Oxygen derived free radicals and synovial fluid hyaluronate.
High performance liquid chromatography with TSK 5000 PW or TSK 6000 PW size exclusion columns combined with a 125I labelled hyaluronic acid binding protein assay was used to study the effects of oxygen derived free radicals on synovial fluid hyaluronate. A continuous flux of free radicals was generated by the xanthine oxidase/hypoxanthine system. When the free radical flux was generated with xa...
متن کاملDetermination of synovial fluid hyaluronate
High performance liquid chromatography (HPLC) with a size exclusion column and ultraviolet monitoring was used to study the effect of synovial fluid hyaluronate concentration and degree of polymerisation on viscosity and mucin clot formation. Rotational viscometry measurements showed an exponential relation between the synovial fluid hyaluronate concentration and relative viscosity, the viscosi...
متن کاملOxygen-Derived Free Radicals in Rats
Myocardial ischemia and reperfusion can evoke excitation of cardiac vagal afferent nerve endings and activation of a cardiogenic depressor reflex (Bezold-Jarisch effect). We postulate that oxygen-derived free radicals, which are well known to be produced during prolonged ischemia and reperfusion, contribute to this excitation. Hydroxyl radicals derived from hydrogen peroxide (H202) activate abd...
متن کاملHyaluronate in normal human synovial fluid.
Studies on hyaluronate in normal human synovial fluid have been hindered by the high viscosity and small volume of fluid available. Reports on hyaluronate levels in normal synovial fluid, in which a number of different methods have been used, have shown discordant results (1-4). Several methods were used in the present study to determine the hyaluronate content of normal synovial fluid. Weighin...
متن کاملDipyridamole inhibits platelet aggregation induced by oxygen-derived free radicals.
Pyrogallol (a generator of superoxide anions) caused 50% increase in platelet aggregation induced by 400 microM of arachidonic acid. Dipyridamole did not produce a statistically significant inhibition of arachidonic-acid induced platelet aggregation, but it caused 100% inhibition of pyrogallol-stimulated platelet aggregation. Ferrous salts (Fe2+) induced 34% platelet aggregation which was inhib...
