Effects of electroacupuncture (EA) on microvessel density in the T13 spinal cord segment in a rat model of intervertebral disc extrusion.
(A) Spinal cord microvessel in the rat model of intervertebral disc extrusion (immunofluorescence staining, × 100). Fluorescent dye is FITC. A1, A2 and A3: Control, model and electroacupuncture groups, respectively. (B) Spinal cord microvessel density values. Microvessel density was calculated as follows: spinal microvascular area/total area of spinal cord section. Data are expressed as the mean ± SEM. Statistical significance between groups was evaluated using the least significant range test. §P < 0.05, §§P < 0.01, vs. control group; ##P < 0.01, vs. model group.
