However, whether Toutongning capsule exerts its effects via endogenous opioid peptides remains poorly understood. This study investigated the effects of Toutongning capsule on enkephalin expression in the midbrain of rats with nitroglycerin-induced migraine headache at the mRNA and protein levels. Results confirmed that proenkephalin mRNA levels were significantly upregulated following treatment with Toutongning capsule. The numbers methionine-enkephalin and leucine-enkephalin-positive cells were significantly greater in the migraine headache rats following treatment with Toutongning capsule compared with the model group. Taken together, these results show that Toutongning capsule exerts potentially beneficial effects by promoting enkephalin expression in nitroglycerin-induced migraine headache rats.展开更多

Methods: The migraine patients in conformity with the conditions were randomly divided into two groups, 34 cases in each group. The treatment group was given EA and the control group was given the routine acupuncture treatment, to observe various pain indexes respectively before and one month after the treatment. Results: The general effect was remarkably better in the treatment group than that in the control group(P<0.05). Conclusion: EA is an effective therapy for migraine without aura.展开更多
