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

Figure 6

Comparisons of serum T-SOD (a), T-AOC (b), and MDA (c) before 1 day as 0 d and after 1d, 7d, 14d, and 28d contusion. After contusion, the activities of the T-SOD and T-AOC dramatically decreased, while the level of MDA sharply increased. The serum levels gradually returned to normal. On days 7, 14, and 28 after contusion, T-SOD and T-AOC activities in the EA group were significantly higher than those of the contusion group (𝑃<0.01) but lower than those of the rhIGF-I group (𝑃<0.01 or 𝑃<0.05) on day 7. On day 28, the EA group was significantly higher compared to the rhIGF-I group (𝑃<0.01). On days 7 and 14 after contusion, MDA level in the EA group was significantly lower than that in the contusion group (𝑃<0.05) but higher than that in the rhIGFI group (𝑃<0.05). 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).
