Figure 5.
PMWT of the CCI rats was measured using Electronic Von Frey tester. CS/GP/Fe3O4/DXM hydrogel significantly reduced allodynia as shown by the increase in PMWT. The data were expressed as the means ± SEM (n = 8 for each group). *P < 0.05, as compared to the CCI group, and &P < 0.05 as compared to the catgut group. Abbreviations: CCI, chronic constriction injury of the sciatic nerve; PMWT, paw mechanical withdrawal threshold.
