Estimation of the Postmortem Duration of Mouse Tissue by Electron Spin Resonance Spectroscopy
Figure 3
(a) Postmortem DMPO-adduct signal intensity in mouse brain. The columns and the lines show the postmortem signal intensity ratios of brain and S.E.M. of the means (n = 8). The -axis shows the percentage of peak signal intensity ratio, which was calculated by assuming that the intensity of MnO (500 nmol/L) was 100%. *, **, versus 0 days. (b) Time course of postmortem DMPO-adduct signal intensity ratio in mice brain. The -axis shows the percentage of peak signal intensity, which was calculated by assuming that the intensity at 3 day postmortem was 100%. -axis is expressed in Log(day). *, **, versus 3 days. The regression lines, correlation coefficient (R1), the square of R1 (R2) and the probability of error (P-value) were calculated.
