TL;DR: The feasibility of detecting methamphetamine and its major metabolite, amphetamine, in postmortem tissues over a 2-year period was examined as discussed by the authors, and the results showed that despite long term storage, drug abuse and/or toxicity could be determined, in all tissues examined.

TL;DR: A screening method for detecting volatile hydrocarbons in blood has been developed using gas chromatography/mass spectrometry with a wide-bore capillary column and a headspace method and Toluene-d8 and indan were used as the internal standards for quantitative analysis.
Abstract: A screening method for detecting volatile hydrocarbons in blood has been developed using gas chromatography/mass spectrometry with a wide-bore capillary column and a headspace method. Toluene-d8 and indan were used as the internal standards for quantitative analysis. Hydrocarbons with retention indices from 600 to 1200 were simultaneously and quantitatively detected in relatively low concentrations (0.01 μg/ml) in reconstructed ion chromatography. This method could prove useful in forensic cases in which urgent examination of complex hydrocarbon mixtures, e.g. petroleum components, is required.

TL;DR: The animals that died rapidly after the injection of compound 48/80, were found to have large increases in levels of histamine and 1-methylhistamine soon after the administration, and these phenomena closely resembled those in the control animals that were treated with overdoses of Nembutal.
