2/100 Hz EA increased expression of β-endorphin in local ankle skin tissues. (a) Representative immunofluorescence images of β-endorphin staining in ankle skin tissues isolated from vehicle (PBS), MSU + Sham EA, MSU + 2/100 Hz EA, and MSU + 2 Hz EA groups. Ankle skin tissues were isolated 30 min after EA or Sham EA treatment. Areas staining positive for β-endorphin were shown in green and nuclei were labeled with DAPI (blue). (b) Summary of the normalized mean fluorescence intensity (%) of β-endorphin staining as shown in (a). The mean fluorescence intensity of PBS group was taken as 100%; other groups were normalized thereafter. Scale bar indicates 20 μm. -6 rats/group. and .
