Abstract:
OBJECTIVEThrough establishing the rat model of CIA to evaluate the effect and mechanism of Rhizoma Drynariae Flavone on bone destruction of CIA rat.
METHODSSubcutaneous injection of bovine type II collagen was used to induce Wistar rats to fall ill, and then established the rat model of CIA. The rats whose inflammation scores reached to two points or above were randomly divided into four groups, and were treated accordingly. The effect of Rhizoma Drynariae Flavone on bone destruction was evaluated.
RESULTSAt 12 weeks after treatment, bone trabecular area percentage and bone trabecular number in Rhizoma Drynariae Flavone group, Rhizoma Drynariae Flavone-1/2 Etanercept group, Etanercept group was obviously higher than that of sterilization water group (P < 0.05); and the trabecular resolving power of these groups was obviously less than that of sterilization water group (P < 0.05).
CONCLUSIONRhizoma Drynariae Flavone can obviously inhibit inflammation of joint bone destruction of CIA rats,the effect may be related with bone trabecular number reduction and trabecular resolving power increasing.
