Analysis of N,N-diethyl-m-toluamide (DEET) in human postmortem specimens

N,N-diethyl-m-toluamide (DEET) levels in postmortem specimens of stomach and contents, blood, liver, and urine are reported following ingestion of the compound. DEET was analyzed by gas chromatography with an OV-101 column and a nitrogen phosphorus detector. The presence of the compound in the four postmortem specimens was confirmed by mass spectrometry.     

Polymorphism of seminal gamma-glutamyl transpeptidase

Electrophoretic analysis of seminal gamma-glutamyl transpeptidase (GGT) activity of 147 unrelated Japanese males revealed three types of band patterns. An anodal single band, a cathodal single band and heterozygous double bands termed 1, 2 and 2-1, respectively, were commonly identified in the samples. The frequencies of the three types were 1 = 0.22, 2 = 0.33 and 2-1 = 0.44. Seminal stains kept for more than 6 months revealed distinguishable band patterns as well as fresh samples.
