| Outline of Final Research Achievements |
In this study, the relaxation time constant of shape recovery process of each red blood cell from various peripheral circulatory failure was measured by based on the standard linear solid visco-elastic mode to evaluate red blood cell deformability by using micro-channel technique.
As the result, time constant of diabetic renal disease could detect only stage G5 as same as a person requiring dialysis, but there was not differences in the case of transitional phase of nephropathy progression. The time constant of the blood from collagen disease was shorter than healthy samples and its deviation in collagen disease sample was mach wider.
And the Sheath flow type micro-channel chip had been successfully developed and fabricated. This newly micro-channel had realized not only high throughput and high resolution testing for erythrocyte deformabiity but also possibility of measuring suspension viscosity with single erythrocyte in a micro channel.
