title: [Study on effects of acupuncture on mice dysmenorrhea model and the mechanism].
abstract: OBJECTIVE
  To probe the mechanism of acupuncture in treatment of dysmenorrhea.
  
  
  METHODS
  Adult mice with no pregnancy were randomly divided into a normal group, a model group, an acupuncture group and a medication group. The model group, the acupuncture group and the medication group were modeled by Diethylstilbestrol and Ocytocin. For the acupuncture group, at the 7th day of modeling, acupuncture was given at "Sanyinjiao" (SP 6), "Diji" (SP 8), once a day, for 5 days; and at the 7th day of modeling, Yimucao Gao 0.6 mg/g was given intragastrically to the medication group for 5 days. The stretching latent period and the number of stretching within 30 min were observed, and mRNA levels of ocytocin receptor (OctR) and vasopressin receptor (VasR) in the uterus tissue were detected with RT-PCR method.
  
  
  RESULTS
  Compared with the model group, the stretching latent period extended (P < 0.05) and the number of stretching within 30 min significantly decreased (P < 0.05); and there were significant differences in the mRNA levels of ocytocin receptor and vasopressin receptor in the uterus tissue in the model group as compared with those in other 3 groups (P < 0.05, P < 0.01).
  
  
  CONCLUSIONS
  Acupuncture can improve the dysmenorrheal symptom to a certain extent, and the mechanism is possibly related to regulative effects of acupuncture on hormones-mediating receptors in mice.
