[Influencing factors of previous testing on blood determination (author's transl)].

The demonstration of individual characteristics, especially those of the blood group types are substantially disturbed through the hydrogenperoxide- and the luminol spray procedure, which when it is previously employed, can cause changes in the blood spot. These changes are expecially by very small blood spots to be expected, but even larger ones under intensive spraying can be effected. Only with great caution are such spray procedures to be used and then only if it is impossible any other way to gather information about the existance of blood spots.

[Demonstration of hemoglobin using the porphyrin test (author's transl)].

The demonstration of hemoglobin after its transformation into Porphyrin is specific and extremely sensitive. It is possible to detect amounts as small as a microgram. The use of sulphuric acid as a reagent is superior to the hydrochloricthioglycol acid method. After obtaining a speciman from a blood stain (usually through soaking) it is recommended that it be concentrated by allowing the speciman once again to dry out. Prejudicial effects due to the extreme sensitivity of this test are therefore avoided.

[Forensic dentistry as an important part of legal medicine].

Forensic dentistry is divided into two main subjects: 1. Dental jurisprudence and ethics and 2. Dental criminology. Dental jurisprudence and ethics include the legal duties of the dentist. They concern foremost the contractual relations between him and the patient and the duties which result from his actual dental activities, especially concerning his therapeutic measures. In major disasters successful identification is possible if a careful register is taken of dental states by all dentists.

[Concerning evidence of parathion (E 605) in an exhumed corpse after 21 months (author's transl)].

In a corpse exhumed after 21 months evidence of E 605 could still be found in the stomach and in the intestinal contents after isolation by steam distillation, extraction with either followed by identification with palladium chloride reagent, as well as by thin layer chromatographicenzymatic detection. A ccording to investigation and analysis, the dose of E 605 administered in the present murder case should have but slightly exceeded the lethal dose.
