title: Transport time for salicylates from blood to joint fluid-- a test of histopathology of the synovial membrane.
abstract: Samples of blood and joint fluid, from sixty patients who had taken Bufferin, were examined for salicylates. The earliest appreance of salicylates occurred in blood between 3 and 13 minutes after intake, and in joint fluid between 11 and 36 minutes. The individual time lapse from the first appearance of salicylates in blood to that in joint fluid, designated the transport time, varied presumably with the changes of the synovial membrane caused by diseases; it was small in synovitis following trauma or focal infection and in osteoarthritis of short duration; it was greater in osteoarthritis, psoriatic arthritis, and rheumatoid arthritis of longer duration, and it showed great variations in immediate traumatic synovitis. Salicylates attained maximum concentration in joint fluid 100 to 155 minutes after intake. Similar factors as above probably accounted for the differences in these time intervals.
