Figure 2

WTG improved bone destruction in CIA rats. (a) Changes in rat body weight after treatment with high (0.45 g/paw), medium (0.3 g/paw), and low doses (0.15 g/paw) of WTG in CIA rats. The body weight was measured before modeling. Drug administration was initiated on day 7 of the CIA modeling, and body weight was measured once a week for 4 consecutive weeks. (b) Histopathological changes in joint tissues after 4 weeks of drug administration. Scale bar = 50 μm. (c) RANKL mRNA levels in joint tissues. (d) RANKL protein levels in joint tissues were tested by Western blot. (e) TRAP levels in serum by ELISA kit. Protein quantification was determined by Image J Mean comparison of multiple groups was subjected to one-way ANOVA with Turkey test. n = 10, , compared to Blank; , compared to Model.
