Abstract:
Objective To study the effects of Duliang capsule on the expression of calcitonin gene‐related peptide(CGRP) and cholecystokinin(CCK) in the midbrain of a rat migraine model ,and explored treatment effects and mechanisms of Duliang cap‐sule on rats with migraine .Methods A total of 24 rats were randomly divided into four groups :normal control groups(A) ,migraine model groups(B) ,Duliang capsule control groups(C) and Duliang capsule treatment groups(D) .C and D were intragastrically per‐fused with Duliang capsule(0 .5 g · kg -1 · d-1 ) .After 7 days ,nitroglycerin was subcutaneously injected into the buttocks of the B and D to induce migraine .Two hours after nitroglycerin injection ,the midbrain were isolated CGRP and CCK expression in midbrain were determined using SYBR Green I real‐time quantitative PCR .Results CGRP mRNA expression was significantly lower in mid‐brains of rats in the Duliang capsule treatment groups compared with migraine model groups(P<0 .05) .CCK mRNA expression was significantly lower in midbrains of rats in the Duliang capsule control groups compared with normal control groups(P<0 .05) . Conclusion Duliang capsule can exhibit the expression of CGRP and CCK in the midbrain of the migraine rats .weaken the CGRP and CCK‐induced inhibition of the analgesic effects of opioid peptides .
