1/2. Experimental evaluation of rigor mortis. VII. Effect of ante- and post-mortem electrocution on the evolution of rigor mortis.

    The influence of electrocution on the evolution of rigor mortis was studied on rats. Our experiments showed that: (1) Electrocution hastens the onset of rigor mortis. After an electrocution of 90 s, a complete rigor develops already 1 h post-mortem (p.m.) compared to 5 h p.m. for the controls. (2) Electrocution hastens the passing of rigor mortis. After an electrocution of 90 s, the first significant decrease occurs at 3 h p.m. (8 h p.m. in the controls). (3) These modifications in rigor mortis evolution are less pronounced in the limbs not directly touched by the electric current. (4) In case of post-mortem electrocution, the changes are slightly less pronounced, the resistance is higher and the absorbed energy is lower as compared with the ante-mortem electrocution cases. The results are completed by two practical observations on human electrocution cases. ( info)

2/2. A fatal methamphetamine poisoning associated with hyperpyrexia.

    After self-administration of 0.05 g of methamphetamine hydrochloride intravenously on three occasions at intervals of 3 h, a 25-year-old female methamphetamine abuser ingested approximately 1.5 g of methamphetamine hydrochloride, and was found dead 3-4 h later. Complete rigor mortis was observed 1-2 h after death and the rectal temperature was 38.4 degrees C 3-4 h after death. Distribution of methamphetamine and amphetamine in the body was analyzed by chemical ionization mass fragmentography. Amphetamine/methamphetamine concentrations (mumol/100 g) were 0.26/28.8 in blood, 0.64/68.2 in brain, 0.96/117.1 in liver, 0.53/50.6 in kidney, and 1.49/1045 in stomach contents. Total amount of methamphetamine hydrochloride in stomach contents was 11.6 mg. Amphetamine in tissues was a metabolite of methamphetamine, and amphetamine in stomach contents resulted from excretion into saliva and gastric mucous excretion. With rectal temperature at death estimated at more than 41 degrees C, it would seem that hyperpyrexia played an important role in causing death from methamphetamine poisoning. ( info)
