We observed the inhibitive effect of electroacupuncture (EA) at Zusanli on inflammatory mediators of postoperative intra-abdominal adhesions to find out the relationship between EA and the cholinergic anti-inflammatory pathway. Sixty-four rats were divided into 8 groups (A-H, each = 8): A = sham control; B = abdominal adhesions model; C = abdominal adhesions plus EA; D = sham acupoint control; E = abdominal adhesions plus vagotomy; F = abdominal adhesions plus EA after vagotomy; G = abdominal adhesions plus α-bungarotoxin (BGT); and H = abdominal adhesions plus EA after α-BGT. α-BGT (1 μg/kg) was injected into the abdominal cavity after surgery, and the bilateral celiac vagotomy was done during the surgery. On the third day the levels of inflammatory mediators (TNF-α, nitric oxide (NO), and nitric oxide synthase (NOS)) in tissues were evaluated. The abdominal adhesion groups developed obvious edema. Compared with sham control, the abdominal adhesion resulted in a significant elevation of inflammatory mediators. EA lowered the elevated levels of inflammatory mediators significantly; EA plus α-BGT and vagotomy showed less anti-inflammatory effects. The activation of the cholinergic anti-inflammatory pathway might be one of the mechanisms of EA at Zusanli acupoints to exert the anti-inflammatory effects.
