[Spin probe mobility in the whole blood of white rats].
By means of ESR-method the rotary mobility of a tanol spin probe is studied in the whole blood of white rats at the temperatures 5.20 and 37 degrees C. It is shown that at all the temperatures the spin probe is localized in the blood plasma and has a value HFS a = (17.1 +/- 0.1) G. By means of linear anamorphism method it is shown on the example of the spectrum central line that the contour is lorenz, i. e. the superposition of the spectra of different sample regions is absent. The spin probe rotation frequency v is a stable blood parameter, the same for 11 rats investigated and dependent only on the blood temperature. For T = 5.20 and 37 degrees C the values have been received v = (86 +/- 2) x 10(8) s-1, (98 +/- 2) x 10(8) s-1 and (107 +/- 3) x 10(8) s-1, subsequently, which compared to v value in water-glycerin system (1:1) (WGS) allow one to calculate the blood microviscosity values (7.2 +/- 0.4), (6.3 +/- 0.4) and (5.8 +/- 0.4) mPds, subsequently. For the mentioned temperatures the non-sphericity parameter epsilon of the spin probe rotation has the values 0.19 +/- 0.03, 0.22 +/- 0.04 and 0.21 +/- 0.05, subsequently that is close to this parameter value for WCS (epsilon = 0.21 +/- 0.02; v = (6 divided by 20) x 10(9) s-1).
