    结果 :治疗 6个月后 ,美托洛尔能够明显改善缺血性心脏病心力衰竭患者的心脏功能 ,使左室射血分数 (LVEF)明显增加 ,左心房内径 (LAD)、左心室收缩末期内径 (LVSD)、左心室舒张末期内径 (LVDD)均明显减小 ,心胸比值降低。
    AIM:To investigate the effects of U50488H(a selective к opioid receptor agonist) on cardiac functions in rats in vivo,and to explore the possibility of reducing addiction and dependence of opioid drugs.
    目的:研究选择性к阿片受体选择性激动剂U50488H对大鼠心脏功能的影响,以探讨减少阿片肽类药物依赖性和成瘾性的可能性。 方法:将实验大鼠按照随机原则分为对照组和U50488H组,观察大鼠心率,动脉压,左心室内压(leftventricularpressure,LVP)及心脏收缩、舒张功能(±dp/dtmax)等指标的变化情况。
    CONCLUSION: The hypoxia induced elevation of plasma endothelin and upregulation of the transcription of mRNA of ETRa,CaM and CaMKII may exert some impacts on cardiac functions.

    Under the same degree of blood pressure control,serum PⅢNP,the ratio of aldosteron and rennin and angiotensin Ⅱ were observed before and after treatment. 42 SD rats(150~200g) were divided into 4 groups,including pseudo-operation group,control group,ACEI group and ACEI+spironolactone group,after partial abdominal artery ligation in superior of renal arteries. After 2 months' treatment,the left cardiac functions were observed in order to verify the effect of anti-aldosterone.

    Cardiac functions of the patients were monitored.
    采用试纸法和速率法分别检验ChE和CPK活性,并观察患者心脏功能改变。
    Objective To investigate the changes of ANF mRNA expression in the myocardial tissues of rat embryo and neonate induced by 2,3,7,8-TCDD so as to determine if TCDD can cause injuries of cardiac functions. Methods SD rat embryos were divided into 4 groups respectively exposed to TCDD at the dose of 0.05,0.5,5,10 μg/kg.
