Fig. 1From: Cat’s whiskers (Orthosiphon stamineus) tea modulates arthritis pathogenesis via the angiogenesis and inflammatory cascadeResults of the prostaglandin concentration in vitro colorimetric assay of the effects of EOS and standard drugs on the activities of COX-1 and COX-2 enzymes. Two EOS concentrations were used (50 and 200 μg/mL). The standard drugs used were acetyl salicylic acid (0.1 μM) for COX-1 whereas, celecoxib (0.05 μM) for COX-2. The results are presented as mean ± SD of 2 independent experiments in 5 replicates each. *** p < 0.001, ** p < 0.01, * p < 0.05 vs. controlBack to article page
