摘要: 目的 观察静脉注射国产降钙素基因相关肽(CGRP)对大鼠血压和心率的影响。方法 给大鼠注射不同剂量的降钙素基因相关肽,观察其对正常血压和肾上腺素所致的血压升高以及心率的影响;同 时观察静脉注射依那普利(1.5 mg/kg)对肾上腺素引起的血压升高的作用。结果 静脉注射CGRP可明显降低大鼠血压并具有剂量效应关系,而对心率无影响;依那普利可显著低肾上腺素所致的血 压升高。结论 降钙素基因相关肽可显著降低大鼠血压,但对心率无明显影响。

Abstract: Aim The effects of intravenous injection of calcitonin gene - related peptide (CGRP) on mean arterial pressure and heart rate in rats were investigated. Methods Different doses o{ CGRP were injected intravenously into rats,and their effects on normal and adrenaline-induced increased arterial pressure and heart rate were observed. Effect of enalapril (1.5mg/kg i.v.) on adrenaline - in- duced increased arterial pressure was also observed. Results The results showed that CGRP re-duced mean arterial pressure significantly, and the effects were dose-related,but it had no effect on heart rate. Enalapril also significantly decreased the adrenaline-induced increased arterial pressure. Conclusion intravenous injection of CGRP into rats significantly decreased mean arterial pressure but had no obvious effect on heart rate.

Key words: Calcitonin gene - related peptide, Mean arterial pressure, Heart rate
