Abstract Cartilage samples were taken from OA patients in order to describe and quantify pro-inflammatory mediators. Samples were cultured under aseptic conditions in Dulbecco’s modified Eagle medium at 37°C for 10 days. Control samples, taken from non-inflammatory cartilage, were cultured under the same conditions. The levels of NO-2 and NO-3 were measured in the supernatant using a spectrophotometric assay. The activity of MMP-1 was quantified by ELISA.
The concentration of NO-x was 47.3 ± 4.1 µM in the OA cartilague and 10.7 ± 1.8 µM in the controls. The average MMP-1 activity was 3,650 ± 387 ng/ml More >
