| Abstract: | AIM: To investigate changes of calcitonin gene-related peptide(CGRP) in myocardial stunning rats. METHODS: Rat in vivo myocardial stunning model was used. CGRP content in plasma and myocardium were determined by radioimmunoassay. RESULTS: Plasma level of CGRP increased significantly (P＜0.01), but in left ventricular myocardium CGRP decreased obviously (P＜0.05) in myocardial stunning group compared with the control group. CONCLUSION: CGRP content in the left ventricular myocardium was negatively correlated with plasma CGRP. |
