Fig. 3From: Pro-inflammatory mediators and neutrophils are increased in synovial fluid from heifers with acute ruminal acidosisAnalysis of the pro-inflammatory mediators in the synovial fluid of heifers with acute ruminal acidosis (ARA). Levels of IL-1β (a), IL-6 (b), PGE2 (c), and ATP (d), in synovial fluid at 0, 9, and 24 h post induction of ARA, were detected. Relative luminescence units (RLU).
