Abstract
Summary
A total of 78 autopsies including 44 jaundice and 34 non-jaundice control cases have been studied for comparative bilirubin levels in vitreous body, spinal fluid, synovial fluid and serum. Ratios of total bilirubin averages in vitreous, spinal and synovial fluid to average total serum bilirubin were 1:220, 1:35 and 1:4 respectively. Highest and average values of total bilirubin found were 0.48 and 0.04 mg/100 ml in vitreous body and 10.5 and 2.02 mg/100 ml in synovial fluid respectively. Total synovial bilirubin in non-jaundice cases averaged 0.28 mg/100 ml. Bilirubin may thus be considered a normal constituent of synovial fluid.
