[The determination of the time of death by the content of free amino acids in the liver and lungs of cadavers using high-performance liquid chromatography].

High-performance liquid chromatography is proposed to be used for assessment of the time of death during a fortnight postmortem. The procedure consists in dynamic measurements of the concentrations of 20 free amino acids in cadaveric liver and lungs of subjects dead from mechanical injuries with or without ethanol in the blood at moderately high temperatures (18 to 23 C) and 40-60% humidity. A working diagram for determination of the time of death is offered and diagnostic microblocks consisting of 5 most informative and stable amino acids developed, permitting the diagnosis of the time of death with 95% reliability.

[The forensic medical assessment of light bodily injuries. 1].

The authors discuss the essence and the criteria of assessment of slight bodily injuries and subdivide such injuries into two categories: those involving short-term health disorders and involving no disorders of this kind. They propose to alter the relevant sections of the actual "Regulations of the Forensic Medical Assessment of the Severity of Bodily Injuries".

[An analysis of fatal poisonings by alcohol surrogates, household chemicals and drugs].

The incidence of lethal poisonings with alcohol surrogates, communal chemical articles, and drugs in various regions of the former USSR was studied. Quantitative characteristics of such poisonings are presented.

[Evaluation of ion activity in determining time of death].

Activity of potassium ions was examined in 3 liquid media of 54 rabbit cadavers by potentiometry with the use of a potassium-selective valinomycin electrode. The reported and obtained data were used for the development of the diagnostic regression equations and the curves to define the time of death from the activity of a complex of 3 ions (potassium, sodium and hydrogen) in the blood serum, CSF and vitreous body fluid. The method is offered for appropriate trials in human cadavers.
