Viscosity of Equine Synovial Fluid

Viskositet i hästsynovia

Abstract

Synovial fluid samples from 51 light horses were examined with respect to their rhéologie properties. The analyses were made with a Rotovisco RV3 rotational viscosimeter. Samples from carpal, stifle and hock joints and from healthy joints, joints with synovitis and joints with infectious arthritis were studied. The analyses showed that synovial fluids from both healthy and diseased joints have complex rhéologie properties. In most samples the viscosity varied with the shear rates, the main exceptions being synovial fluids from joints with infectious arthritis. Flow curves (flow behaviour), rather than single observations on viscosity, were considered to be representative for the synovial fluids examined.

Sammanfattning

Synoviaprover från 51 varmblodiga hästar undersöktes med avseende på deras rheologiska egenskaper. Analyserna utfördes med en Rotovisco RV3 rotationsviskosimeter. Prover från karpal-, knä- och hasleder samt från friska leder, leder med synovit och leder med infektiös artrit undersöktes. Analyserna gav vid handen, att synovia från såväl friska som sjuka leder äger komplicerade rheologiska egenskaper. I de flesta prov varierade viskositeten, när skjuvningshastigheten (shear rate) ändrades. Undantagen var framför allt synoviaproverna från leder med infektiös artrit. Resultaten tolkades så, att flytkurvans utseende snarare än enstaka viskositetsbestämningar var representativ för respektive synoviaprov.
