After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

There was a good correlation between Ptw,AVCtw,MVOtw,PTV,PUV,UntwR and age.2.Assessment of left ventricular twisting and untwisting of DCM patients19 DCM patients(range 18-80 yr,mean age 50.52±17.52 yr,2 females) and 21 age- and sex-matched normal controls(range18-80 yr,mean age 49.05±16.94 yr,5 females) were enrolled into this study.Then DCM patients were divided into two groups:E/A＜2 group and E/A＞2 group.The routine echo showed the left ventricle dilated and EF decreased.The results show that LV rotation degree, rotation velocity at baseline and apex were irregular changeable with the cardiac cycle;the rotation direction was clockwise at the base and counterclockwise at the apex,and are combined to yield a systolic counterclockwise twisting as seen from the apex,but the rotation at the basal and apex were the same direction in some patients.

扩心病患者左室扭转及解旋特征的研究选择扩张型心肌病(Dilated Cardiomyopathy，DCM)组患者19例(男性17例，女性2例，年龄18～82岁，平均50.52±17.52岁)，健康体检者21例(男性16例，女性5例，年龄18～80岁，平均49.05±16.94岁)作为对照组，扩心病患者按照E/A分为E/A＜2、E/A＞2两个亚组，结果显示：常规超声显示DCM组LVDd值增大，EF值减小；DCM患者左室心底部与心尖部心肌旋转角度、旋转速度随心动周期变化曲线明显紊乱；与正常组比较，DCM患者左室整体扭转角度和速度分别为(6.49±1.82)°、(67.84±15.60)°/s，较正常人显著减低P＜0.01左室舒张末及收缩末扭转角度DCM患者较正常人显著减低(P＜0.01，左室舒张末及收缩末时间在DCM-E/A＞2组较正常人及DCM-E/A＜2组显著缩短P＜0.01DCM患者左室解旋速度较正常人亦显著减低(P＜0.01，左室功能轻中度减低(DCM-E/A＜2)患者解旋率[(0.29±0.07)%]较正常人[(0.42±0.11)%]明显减低，但当左室功能重度减低(DCM-E/A＞2)时左室解旋率[(0.63±0.35)%]较正常人反而增加；左室整体扭转角度、舒张末扭转角度、收缩末扭转角度、解旋与左室射血分数未见明显相关性。3。
