THE USE OF ULTRASOUND IN SYNOVIAL FLUID ANALYSIS

Ultrasound is proposed as a means of reducing synovial fluid viscosity. Ultrasound reduced the relative viscosity of synovial fluid as satisfactorily as hyaluronidase digestion. Comparison of the effect of ultrasonic treatment and of testicular hyaluronidase treatment on various constituents of synovial fluid from patients with rheumatoid arthritis revealed no significant difference with respect to (1) the titer of rheumatoid factor as determined by the latex and sensitized sheep cell tests, (2) the serum protein distribution as determined by cellulose acetate and paper electrophoresis, and (3) the beta‐glucuronidase and acid phosphatase activities. Le uso de undas ultrasonic es proponite como medio pro reducer le viscositate de liquido synovial. Undas ultrasonic se ha provate capace a reducer le relative viscositate de liquido synovial non minus satisfacentemente que digestion a hyaluronidase. Un comparation del effecto de tractamento a undas ultrasonic e de tractamento a hyaluronidase testicular super varie constituentes de liquido synovial ab patientes con arthritis rheumatoide ha revelate nulle significative differentias in (1) le titros de factor rheumatoide secundo determinationes per tests a latex e a sensibilisate cellulas ovin, (2) le configurationes seral de proteinas secundo determinationes per electrophorese a acetato de cellulosa e a papiro, e (3) le activitates de glucuronidase beta e de phosphatase acide.
