Figure 6

Glycosaminoglycan (GAG) remaining in the cartilage extract treated with reactive oxygen species (ROS) or antioxidative agent in tissue culture. Catabolic change in articular cartilage matrix was analyzed by determining the GAG content remaining in the cartilage extract relative to the total amount of GAG in the supernatant and the cartilage digest. Values are expressed as mean ± standard deviation of nine donors (three cartilage extracts per donor). *P < 0.05, **P < 0.01, versus control group at each incubation time.
