Abstract:

BACKGROUND: Interleukin-6, is a cytokine that has wide sources. Interleukin-6 increases in the skeletal muscle after exercise, which plays an important role in motor function recovery. Acupuncture at the skeletal muscle after exercise can improve the ultrastructure of skeletal mscle, alleviate injury and promote functional recovery. However, acupuncture effects on the interleukin-6 post exercise remains unknown.
OBJECTIVE: To explore the influence of acupuncture intervention on interleukin-6 in rats after eccentric exercise.
METHODS: Totally 114 male Sprague-Dawley rats were randomly divided into four groups: control group (n=6), exercise group (n=36), acupuncture group (n=36) and exercise plus acupuncture group (n=36). The rats in the exercise and exercise plus acupuncture groups were submitted to eccentric exercise on a downward treadmill at 16° decline. The rats in the acupuncture and exercise plus acupuncture groups were subjected to the oblique acupuncture at the triceps surae. Samples except the control group were collected at 0, 2, 24, 48, 72 and 120 hours after treatment (n=6 per group at each time point). Protein expression level of interleukin-6 in the soleus and rectus femoris was detected by western blot assay. The plasma level of interleukin-6 was determined by ELISA.
RESULTS AND CONCLUSION: In the acupuncture group, the protein expression level of interleukin-6 in the soleus and rectus femoris and plasma level of interleukin-6 showed no significant changes (P > 0.05). After eccentric exercise, the interleukin-6 levels in the soleus, rectus femoris and plasma were significantly increased, and the protein expression level of interleukin-6 did not differ significantly between soleus and rectus femoris (P > 0.05). Acupuncture intervention after exercise, the protein expression level of interleukin-6 in the soleus was significantly reduced (P < 0.05), while interleukin-6 levels in the rectus femoris and plasma showed no significant change (P > 0.05). These findings imply that acupuncture cannot markedly change the interleukin-6 level in normal rats. Eccentric exercise can lead skeletal muscle to create more interleukin-6, and acupuncture intervention after eccentric exercise can reduce the amount of interleukin-6 at peak phase in the needling part. But its effect is local, not significant on the skeletal muscle of other parts and plasma.
