Fifteen patients undergoing hysteromyomectomy with 0 75% bupivacaine epidural anesthesia were studied to observe the alterations of the levels of plasma atral natriuretic peptide, renin activity, angistensin Ⅱ and aldosterone systems.

研究了15例子宫肌瘤切除术患者应用0.75％布比卡因硬膜外麻醉血浆心钠素和肾素活性、血管紧张素Ⅱ－醛固酮系统的变化及相互调控。结果表明，血浆ANP水平在麻醉10min后各时点明显低于麻醉前（P＜0.05），PRA在麻醉10min后亦明显低于麻醉前（P＜0.01），而AⅡ和AL无显著改变（P＞0.05）。

Objective To study the effects of angiotensin Ⅱ receptor antagonist valsartan on intrarenal mRNA expressions of ETA and ETB in diabetic rats.

目的 观察血管紧张素受体拮抗剂缬沙坦对糖尿病大鼠肾脏内皮素受体A、内皮素受体B基因表达的影响。

Venous blood was drawn from 35 old hypertension patients when blood pressure was nomial and abnormal, respectively. Epinephrine. norepinephine, endothelins, angiotensin Ⅱ and calcitonin-gene-related peptide were determined by radio-immunity. The above five cytokines were also determined in 33 old healthy people. The cytokines levels were compared between the normal and abnormal blond pressure in hypertension patients and also between the old hypertension patients and healthy persons. The correlation between blood pressure and cytokines were analyzed.

35例老年EH患者，血压正常时和血压波动时各抽取静脉血一次，放射免疫法检测肾上腺素、去甲肾上腺素、内皮素、血管紧张素Ⅱ和降钙素基因相关肽水平，同时检测33例健康老年人群各因子水平，比较EH患者血压波动前后各因子水平的差异和血压正常范围时两组人群各因子水平差异，分析不同状态下血压和各因子水平之间的相关性。

Cardiac hypertrophy and extracellular matrix remodeling happened as a result of chronic overrange of pressure in heart and hypervolaemia which lead to damage of relaxation and compliance of heart.Drugs including renin-angiotensin converting enzyme inhibitor,angiotensin receptor blocker,aderergic receptor blocker,aldrosteron antagonism,tatins endothelin receptor blocker pancreatic kiniogenase and calcalium channel blocker,can delay or reverse the remodeling by several mechanisms.

Objective To observe the effect of nesiritide glycerol trinitrate, dobutamine on renin and aldosterone in patients with intractable heart failure.

目的 观察在应用新活素、硝酸甘油、多巴酚丁胺治疗失代偿心力衰竭伴轻度肾功能不全时对肾功能、肾素、血管紧张素、醛固酮系统的影响。

Methods:The serum concentrations of endothelin、angiotensionⅡ、nitric oxid、adrenomedullin and urinary albumin excretion rate were measured in 40 diabetic patients with nephropathy before and after treatment with shuxuening.

测定40例糖尿病肾病患者治疗前及应用舒血宁治疗后血浆内皮素、血管紧张素Ⅱ、一氧化氮、肾上腺髓质素水平及尿白蛋白排泄率变化。
