本文对５０例脑梗塞患者予以低能量Ｈｅ－Ｎｅ激光血管内照射治疗，观察治疗前后血液流变学、血脂和载脂蛋白的变化．结果表明，脑梗塞组与正常对照组比较，前者在全血低切比粘度、全血高切比粘度、血浆比粘度等多项指标均比后者增高，且其差异有非常显著意义（Ｐ＜０．０１）．而５０例患者接受低能量Ｈｅ－Ｎｅ激光血管内照射治疗后，这些增高的指标均有不同程度的改善（Ｐ＜０．０５）．总胆固醇、甘油三脂、载脂蛋白Ｂ水平在接受治疗后也有下降（Ｐ＜０．０５）．
In this paper, 50 patients with cerebral infarction were treated with low-energy He-Ne laser intravascular irradiation to observe the changes of blood rheology, blood lipids and apolipoproteins before and after treatment. The results showed that compared with the normal control group, the former of the cerebral infarction group had a higher number of indicators such as low shear rate whole blood viscosity, whole blood high shear rate viscosity and plasma specific viscosity, and the difference was significant (P <0.01). However, all of the 50 patients were treated with low-energy He-Ne laser intravascular irradiation, all of which were improved to some extent (P <0.05). Total cholesterol, triglycerides and apolipoprotein B levels also declined after treatment (P <0.05).
