[Experimental study of erythrocyte deformation].
A laser diffraction system was used to study the deformation of RBC. This work indicated: 1. There was a decreased tendency accompanied with age increased, especially at pre-elderly period. 2. The deformability of patients with acute ischemic stroke was significantly decreased. This result emphasized that DI value should be considered as a peculiar index for diagnosis and treatment. 3. Abnormal calcium accumulation in RBC may play a crucial role in governing RBC deformability. It provided one of the basis of potential therapy of calcium antagonist. 4. The quantitative relation of deformation and SOD activity of RBC need to be researched.
