[Morphologic identification of mummified tissue traces].

Post mortem tissue samples from various human organs (skin, muscle, liver, kidney, brain) were stored at room temperature for a period of one year. During this time the samples were regularly histologically tested. Without any pretreatment of the samples a histological preparation and identification was no longer possible after only a few hours. By the use of a rehydration solution consisting of absolute ethanol (30 ml), aqua dest. (50 ml) and 0.2 M phosphate buffer pH 7.0 (20 ml) a reconstitution and identification was again possible. Further immunhistochemical examinations were also unaffected by the solution. The use of microwave stimulation allowed a reduction of the rehydration process from 24 hours to only 4 hours.
