The Time Course Effects of Electroacupuncture on Promoting Skeletal Muscle Regeneration and Inhibiting Excessive Fibrosis after Contusion in Rabbits

Figure 5

Repeated use of LDPI at the contusion site in different groups after contusion (a). Comparisons of the microcirculation perfusion of GM on days 7, 14, and 28 after contusion (b). In the contusion group, the contusion area was mainly blue and green, with only a small amount of yellow and red. On day 7 in the EA and rhIGF-I groups the images were mostly green, yellow, and red. The red area was expanded on days 14 and 28. The microcirculation perfusion in the contusion group was markedly lower than that in the normal group (𝑃<0.01). The EA group was apparently more than the contusion group (𝑃<0.01) but significantly lower than the rhIGF-I group (𝑃<0.05 or 𝑃<0.01). Contusion versus normal, ^★𝑃<0.05, ^★★𝑃<0.01; EA versus contusion, ^#𝑃<0.05, ^##𝑃<0.01; and EA versus rhIGF- I, ^▴𝑃<0.05, ^▴▴𝑃<0.01 (𝑛=5).
