Fig. 4From: Repeated electroacupuncture treatment attenuated hyperalgesia through suppression of spinal glial activation in chronic neuropathic pain ratsImmunofluorescence staining showing activities of microgliacytes and astrocytes in Ipsi and Cont DHs of lumbar spinal cord on day 6 and 18 after CCI in rats. a Representative tissue sections of immunofluorescence staining showing Iba-1-labeled microgliacytes (red) and GFAP-labeled astrocytes (green) in the Ipsi DHs of the lumbar spinal cord. In the superior-right corner of each section, the magnified microgliacyte and astrocyte from each dashed square box are shown. b Bar graphs showing the numbers of microgliacytes and mean fluorescence intensity values of GFAP (for astrocytes) in the Ipsi DHs on day 6 and 18 in the sham and EA groups(mean ± SD, n = 6/group). Results showed that in the early period of CCI-induced neuropathic pain, 2 days’ EA suppressed the activation of microgliacytes (not astrocytes), and in the later period, 2 weeks’ EA suppressed the activation of astrocytes. # P < 0.05, vs the CCI group)Back to article page
