    Abstract:
    OBJECTIVE: To explore the effects of electroacupuncture on exercise-induced immunosuppression in rats and its mechanism. METHODS: Sports immunosuppressive model was established successfully by the rats were conducted high intensity swimming training 150 min/day, 6 days/wk for 8 weeks in this study. Forty-three SD rats were randomly divided into a control group (group A, n = 10), a high intensity swimming training group (group B, n = 17), and a high intensity plus electroacupuncture group (group C, n = 16). Group A did not receive any intervention. Group B was conducted 150 min/day, 6 days/wk swimming training for 8 weeks. Group C was treated with electroacupuncture at "Baihui" (GV 20), "Guanyuan" (CV 4) and "Zusanli" (ST 36) after every exercise-time from the second week, once each day for 7 weeks. The changes of the rats' weight, gamma-interferon (gamma-IFN), interleukin-2 (IL-2), solubility IL-2 receptor (SIL-2R) and nature killer cell (NKC) were detected. RESULTS: (1) Compared with group A, gamma-IFN and IL-2 in group B were significantly decreased (P < 0.01, P < 0.05), and NKC in group C was significantly increased (P < 0.01). Meanwhile, gamma-IFN and NKC in group C were both significantly higher than that in group B (P < 0.05, P < 0.01). (2) Compared with group A, the weight of the rats in group B and group C were significantly decreased (both P < 0.01), but SIL-2R in group B was significantly increased (P < 0.05). The weight of the rats in group C was significantly higher than that in group B (P < 0.05) and SIL-2R in group C was significantly lower than that in group B (P < 0.01). CONCLUSION: Lasting gravis exercise stress does decrease the immune function in rats and is even inhibited significantly, but electroacupuncture can up-regulate the exercise-induced immunosuppression.
