[Retracted] Effect of Ropivacaine-Loaded Magnetic Nanoparticles on Ankle Nerve Block in Rats

Figure 2

PWT (g) values. PWT values at T2-T4 were higher in nerve block control group and MNP/Rop group than in blank group, and they remained slightly higher in MNP/Rop group than in nerve block control group. Note: a denotes . PWT: paw withdrawal threshold; PWL: paw withdrawal thermal latency; Rop: ropivacaine; MNP: magnetic nanoparticles.
