title: [Effects of acupuncture on NO and NOS in restoration environment of interstitial cells of Cajal after colonic anastomosis].
abstract: OBJECTIVE
  To explore the mechanism of acupuncture on promoting the restoration of interstitial cells of Cajal (ICCs).
  
  
  METHODS
  Thirty SD rats were randomly divided into a blank group, a model group and an acupuncture group, ten rats in each one. The rats in the model group and acupuncture group were treated with colonic anastomosis to establish the model. After successful establishment of the model, the rats in the acupuncture group were treated with acupuncture at bilateral "Zusanli" (ST 36), "Sanyinjiao" (SP 6) and "Taichong" (LR 3) for 15 min, once a day for 10 days. Rats in the model group and blank group were put into the fixator for 15 min at the same time daily. The propulsive rate of small intestine was measured in each group. Colonic tissues were collected to detect c-kit expression by using immunohistochemistry. The nitricoxide (NO) content was measured by nitrate reductase method and nitric oxide synthase (NOS) activity was measured by method of L-arginine.
  
  
  RESULTS
  Compared with the blank group, the propulsive rate of small intestine in the model group was decreased; NO content was increased; iNOS activity was elevated; cNOS activity was declined; total NOS (tNOS) activity was increased and the counting of c-kit positive ICCs was decreased (all P < 0.05). Compared with the model group, the propulsive rate of small intestine in the acupuncture group was increased; NO content was decreased; iNOS activity was reduced; cNOS activity was elevated; NOS activity was decreased and the counting of c-kit positive ICCs was increased (all P < 0.05).
  
  
  CONCLUSIONS
  Acupuncture can regulate NO content and NOS activity in postoperative restoration environment of ICCs, which may participate in the process of acupuncture promoting the restoration of ICCs.
