Osmotic pressure gradients and joint effusions

This study reveals that in rheumatoid joint disease the total osmotic pressure of synovial fluid tends to be lower than, or equal to, that of plasma. With local articular or general systemic improvement the total osmotic pressures of synovial fluid and plasma tend to increase, and that of synovial fluid may exceed that of plasma. The colloid osmotic pressure of synovial fluid from joints of patients with rheumatoid arthritis was lower than that of plasma. Le presente studio revela que in morbos rheumatic del articulationes le total pression osmotic del liquido synovial tende a esser inferior o equal a illo de plasma. Con local melioration articular o con melioration constitutional, le total pressiones osmotic del liquidos synovial e del plasma tende a montar, e illo del liquido synovial pote exceder illo del plasma. Le colloide pression osmotic de liquido synovial ab articulationes de patientes con arthritis rheumatoide esseva inferior a illo del plasma.
