(a) Mean plasma concentration-time curve of dosage of 0.572 mg/kg. The values are expressed as mean ± SD (n = 5); (b) Mean plasma concentration-time curve of dosage of 1.2 mg/kg. The values are expressed as mean ± SD (n = 5). **p < .01 vs free COL, *p < .05 vs free COL; (c) The swelling degree of rats' joint after molding for 12 h; (d) The perimeter change of rats' joint. The values are expressed as mean ± SD (n = 5); (e) The measurement of PGE-2 and TNF-α of rats' joint. The values are expressed as mean ± SD (n = 5). ##p < .01 vs negative control; **p < .01 vs model, *p < .05 vs model.
