[Establishing the time of death by the constant of the reaction rate of spin-label reduction].

The rate of the spin probe reduction by tongue homogenates was measured on postmortem days 15, 30, 45, 60, 75, 105, 135, 150, 165, 180, 195, 210, 225, and 240 in order to evaluate the possibility of determining the time of death by this test. The constant of the rate of phenol probe reduction by tongue homogenates was used as the diagnostic sign of the time elapsed since death. The results indicate that using this parameter, the time of death may be determined within the period from 4 to 8 months postmortem.
