摘要
目的:观察附子对缓慢性心律失常大鼠模型cAMP-PKA信号转导通路的影响。方法:用普萘洛尔制备缓慢性心律失常大鼠模型,观察附子对缓慢性心律失常大鼠心率、SOD、MDA、AST、LDH、CK、Na+-K+-ATP酶、cAMP及cAMP-PKA信号转导通路的影响。结果:附子水提10,5,2.5g生药/kg能升高大鼠心肌Na+-K+-ATP酶的活性和cAMP,PKA的含量,这可能是其治疗缓慢性心律失常的机制之一。结论:附子10g/kg具有明显的抗缓慢性心律失常的作用。
Objective: To observe the effects of Fuzi on chronic arrhythmia rat.Methods: Preparing the model of chronic arrhythmia by propranolol,explore effects of Fuzi on cAMP-PKA signal transduction pathways of chronic arrhythmia.Results: Compared with model group,there are difference,Fuzi(10,5,2.5g / kg) groups raise the acyivity of Na+-K+-ATP enzyme and content of cAMP,PKA,it may be one of the mechanism of treating chronic arrhythmia.Conclusion: Fuzi(10g / kg) has obvious treating chronic arrhythmia.
