摘要
目的 :探讨高血压性与运动性心肌肥厚的产生机制的差异。方法 :以缩窄大鼠的腹主动脉加盐负荷制作高血压性心肌肥厚 ,以游泳运动制作运动性心肌肥厚模型 ,用特异性放射免疫测定技术 ,检测心肌组织和血浆中降钙素基因相关肽 (CGRP)的含量。结果 :高血压组大鼠心肌组织和血浆中CGRP含量显著低于运动组和对照组 (P <0 0 5 )。结论 :CGRP可能在降低心肌肥厚程度中具有一定作用 ,并有利于肥厚心肌血液供应 ,使心肌收缩功能增强。
Objective:To investigate the differences in developing mechanism between hypertensive myocardial hypertrophy and exercised myocardial hypertrophy. Methods:The model of hypertensive myocardial hypertrophy was made by constricting abdominal aorta of rats and feeding salt, and exercised myocardial hypertrophy by swimming exercises. Specific radioimmunoassay was applied to test the content of CGRP in myocardium and plasma. Results:The content of CGRP in both myocardium and plasma in hypertensive group is significantly lower than tnat in exercise group and control group (P<0 05). Conclusion:CGRP has relation to the development of myocardial hypertrophy. CGRP can reduce hypertrophy degree of myocardium, and improve blood supply of hypertrophic myocardium and enhance contracting function of myocardium.
