Abstract (in Japanese) (See Japanese page) 
(in English) For evaluating the quality of hemodialysis from the limited volume of human blood using a commercially available open-ended coaxial probe, we previously measured for 10 normal healthy subjects and 9 patients who require hemodialysis the dielectric properties of 2.5 ml whole blood with a temperature of 25 degrees centigrade in a syringe with a diameter of 20 mm and a depth of 8 mm. In this study, we measured the complex relative permittivity of water and human blood when changing temperature from 25 to 37 degrees centigrade in order to examine the correlation between them, and calculated their Pearson product-moment correlation coefficients for &#61541;rt&#61602; and &#61541;&#61602;&#61602; along with significant probability P based on a t-test. It should be noted that P is a reference probability to determine whether or not a null hypothesis can be rejected, and that the P value of 0.05 is commonly used as a significance level for a statistical test. As a result, it was found for the complex relative permittivity of water that there is approximately good agreement between the measured results and calculated ones from the Kaatze formula expressed as a function of temperature, and that strong correlations with P < 0.05 are also confirmed between the complex relative permittivity and temperature. For the human blood, on the other hand, we found that a strong correlation with P < 0.05 is observed between &#61541;&#61602;&#61602; and temperature, while there is not always significant correlation with P > 0.05 between &#61541;&#61602; and temperature.
