Death By Drowning

Death by ‘drowning’ is classically considered asphyxiai in nature although there is frequently little evidence to support this concept at post-mortem examination. The results of the use of two simple tests as an aid to the scientific assessment of the cause of death of deceased persons found dead in salt and fresh water are given. The role of prior consumption of alcohol in deaths by immersion is discussed.

Quantification Method

Objective: Evaluate the applicability of using the method of quantifying the RNA degradation extracted from dental pulps to estimate the post mortem interval, by simulating drowning conditions with teeth submerged in fresh water and exposed to different time intervals. Material and methods: The sample consisted of 80 human teeth (third molars), which were divided into eight groups and submitted to the aquatic environment, for pre-established periods of three days, and 1, 2, 3, 4, 8, 12 and 16 weeks. After the stipulated time and the recovery of the teeth, the removal of the dental pulp, extraction of the RNA molecule and analysis of the degradation of the molecule were carried out. Results: After the analysis, the highest number of RNA molecule (RIN) found was 6,50 and the results showed very degraded molecules, highlighting the fact that the samples were submitted to the environment, simulating real day-to-day conditions, which may have been a primary factor to justify the results found in this work. Conclusion: RNA degradation quantification method is not applicable, since it was not possible to establish a connection between the degradation of the RNA molecule and the estimation of the post mortem interval.

Cherax Destructor

Sodium balance was examined in C. destructor. E. spinifer and E. keirensis to assess the degree of adaptation to fresh water and to permit comparisons with the better known astacoid crayfish of the Northern Hemisphere. The crayfishes had blood ion concentrations close to those reported in the Astacoidea and permeability to sodium ions was similarly low. The affinities of the sodium pumps for sodium ions were relatively low but this was compensated for by an unusually high rate of uptake of sodium following depletion, which enabled sodium balance to be maintained at low external concentrations. Adaptation to fresh water in the species examined is less advanced than in the astacoid species studied.
