急性脑梗塞患者红细胞膜微粘度改变与脂质过氧化的关系

用荧光偏振法测定了 36例急性脑梗塞患者红细胞膜微粘度 ,同时对血浆 MDA、SOD含量进行了测定 ,并与 2 4例正常人进行比较。结果显示 :脑梗塞组红细胞膜微粘度与对照组比较呈显著性升高 (P <0 .0 0 1 ) ,其改变与血浆 MDA水平呈正相关 ,与血浆 SOD水平呈负相关。说明脂质过氧化可能是导致急性脑梗塞红细胞膜微粘度增大、红细胞膜脂流动性降低的直接原因之一。     

EFFECTS OF THROMBOLYSIS WITH ULTRASOUND ON THE STRUCTURE OF ERYTHROCYTE AND ITS SAFETY THRESHOLD

The study was to investigate thrombolysis in vitro with ultrasound, and to discuss effects of thrombolysis with ultrasound on the structure of erythrocyte and its safety threshold under different ultrasound intensity and exposure time. The structure of erythrocyte in thrombus was evaluated under light microscope. The relationship between the structure of erythrocyte in thrombus and ultrasound intensity and exposure time was obtained. The results showed that ultrasound eliminated the thrombus. According to the change of the structure of erythrocyte in thrombus and ultrasound intensity and exposure time, the effects of thrombolysis with ultrasound could be divided into three kinds of areas： the A, B, C area. The area A was the safe area, the area B was the relatively safe area, and the area C was the irreversible damage area. The study suggested that ultrasound intensity and exposure time had significant impact on the structure of erythrocyte. Stronger ultrasound intensity or longer exposure time could cause erythrocytes irreversible damage. It could accelerate thrombolysis and shorten the exposure time that the ultrasound intensity was little bit increased. The study of effects of thrombolysis with ultrasound on the structure of erythrocyte and its safety threshold were important for practical applications.     

老年女性血沉正常参考值与海拔高度的曲线模型分析

目的　为制定中国老年女性血沉正常参考值的统一标准提供科学依据。方法　收集了中国 2 0 2个单位用温氏法测定的 11783例健康老年女性血沉正常参考值 ,用曲线回归分析的方法研究了其与海拔高度之间的关系。结果　发现随着海拔高度的逐渐增大 ,老年女性血沉正常参考值按指数律在逐渐的减少 ,相关性很显著 (R =0 .70 1) ;推导出了一个曲线回归模型 ^Y =2 5 .98e-0 .0 0 0 3 0 1x ± 5 .31。结论　如果知道了中国某地的海拔高度 ,就可以用该回归模型估算这个地区的老年女性血沉正常参考值。依据老年女性血沉正常参考值与地理因素的依赖关系把中国分为青藏区、中部区、东部区等三个区
