    Description / Table of Contents: Zusammenfassung Nach Einnahme einer tödlichen Menge von Codein wurde die Substanz in postmortalen Geweben bzw. Flüssigkeiten durch eine GC-MS Methode bestimmt. Die Blutkonzentration von Codein war 22,1 mg/l. Die Ergebnisse sind beschrieben im Vergleich mit der bezüglichen Literatur.
    Notes: Summary Capillary gas chromatography coupled to mass spectrometry was employed to quantify codeine in biological fluids and tissues in a death attributed to oral codeine ingestion. The blood concentration of codeine was 22.1 mg/1. Results are discussed in the light of the existing literature.

    Description / Table of Contents: Zusammenfassung Der Nachweis von Restriktionsfragmentlängen-Polymorphismen (RFLP's) (1) aus DNA, welche von forensischen Proben extrahiert wurden, bleibt häufig unmöglich wegen Verschlechterung, Kontamination des biologischen Materials and extrem geringer Mengen, welche isoliert werden können. Die Polymerase-Kettenreaktion (PCR) ist eine neue und ganz besonders geeignete Methode, um sehr kleine Mengen (10–20 ng) degradierter DNA zu analysieren und zu typisieren (2, 3). DNA-Analysen auf der Ebene weniger Zellen in forensischen Proben wie Blutspuren, Samenspuren, Scheidenabstrichen und Haarwurzeln erscheint nunmehr möglich mit Hilfe der DNA-Amplifikation. Ein PCR-Protokoll (4, 5) wurde adaptiert, um gleichzeitig eine Y-spezifische DNA-Sequenz vom DYZ1-Locus (6) und eine X-spezifische DNA-Sequenz vom DXS424-Locus (7) zu amplifizieren. Das co-amplifizierte y-spezifische DNA-Fragment (102 Bp) und das X-spezifische DNA-Fragment (181-199 Bp) wurden mit einem Ethidiumbromid gefärbten 4% igen Agarosegel sichtbar gemacht. Der männliche oder weibliche Typ der amplifizierten DNA, welche von Blutproben, Blutspuren, Spermaspuren, Vaginalabstrichen, Hirngewebe und 1, 2, 5 oder 10 Haarwurzeln extrahiert worden war, wurde bestimmt.
    Notes: Summary The detection of restriction fragment length polymorphisms (RFLP) (1) in DNA extracted from forensic samples remains impossible in a significant number of cases due to deterioration and contamination of the biological material and the extremely low quantities of DNA isolated. The polymerase chain reaction (PCR) is a recent and particularly convenient method for analysing and typing very small amounts (10–20ng) of degraded human DNA (2, 3). DNA analysis at the level of a few cells present in forensic samples such as bloodstains, semen stains, vaginal swabs and head hair bulbs now appears possible using DNA amplification. A PCR protocol [4, 5] was adapted to simultaneously amplifiy a Y-specific DNA repeat sequence from the DYZ1 locus [6] and an X-specific DNA repeat sequence from the DXS424 locus [7]. The co-amplified Y-specific DNA fragment (102 bp) and X-specific DNA fragments (181–199 bp) were visualized on an ethidium bromide-stained 4% agarose gel. The male or female type of the amplified DNA extracted from blood samples, bloodstains, semen stains, vaginal swabs, brain tissue and 1, 2, 5, or 10 head hair bulbs was determined.

    Notes: Abstract The polymorphism of the two hypervariable segments (HVI and HVII) of the control region of mtDNA was analyzed in a population of 154 unrelated individuals from south west Switzerland using a fluorescent based capillary electrophoresis sequencing method. In our population data of 154 random individuals, ¶137 mtDNA types were observed. Of these, 124 sequences were observed only in one individual whereas 10 sequences were observed in 2 individuals, 2 sequences in 3 individuals and 1 sequence in 4 individuals. The probability of two unrelated individuals having the same sequence was 0.84%. The results were compared with four other Caucasian populations. Furthermore, the usefulness of the mtDNA sequencing was tested, for exclusion and inclusion, in 18 forensic cases including 69 evidence samples and 44 reference samples. Despite the fact that 55% of the evidence samples yielded a negative result for the nuclear DNA with the human dot quantitation system, the success rate of the mtDNA sequencing was 71.0%. This validation study proves the great usefulness and sensitivity of the mtDNA sequencing technique using nested PCR and fluorescent capillary electrophoresis.
