In the current study the objective was to find to what extent a reliable determination of age at death is made possible by establishing the degree of aspartic acid racemization in the dentin of teeth. The results of the investigation of 46 teeth are in agreement with the values found by other authors. The method presented makes a reproducible and accurate estimation of age possible. We intend to elaborate and improve this promising method for determination of age at death. The relevant points are presented here. 相似文献

Quadratic pieces of fleece measuring 16 mm2 were soaked with 10 different blood-samples in the dilution steps of 1:1, 1:10, 1:100, 1:1000, respectively, and were tested in blood group typing and identification tests of forensic serology. The above spezified dilutions correspond with 5 microliters, 0.5 microliter, 0.05 microliter and 0.005 microliter of blood, respectively. The detection limit of the microspectrometric test for blood was the dilution 1:10, of the porphyrine test a dilution above 1:100, whereas the preliminary test for blood (peroxidase) succeeded always up to a dilution of 1:1000 and the species determination by the radial immunodiffusion test in agar gels succeeded in most cases op to a dilution of 1:1000. The detection limit of the anti-human globulin inhibition test was between the dilution steps 1:10 and 1:100 when non-titrated and undiluted anti-human globulin serum was used. Gc- and ABO-grouping were possible up to a dilution of 1:100 and were thus the most sensitive grouping systems. Phenotyping of the enzyme-systems and the Gm/Km-system usually required stains with considerably higher blood concentrations i.e. stains of undiluted blood. 相似文献

The purpose of this study is to review 23 causes of death that have occurred in Western-Austrian prisons from 1974 to 1989. The majority of them (11 cases) were due to suicides. Among 9 cases of natural death there was a 25 years old man, who died of an unknown purulent meningoencephalitis. Two drunken prisoners had not been supervised and therefore died of alcohol poisoning. In one case the police jail physician did not recognize an epidural hematoma. 相似文献

This study concerns the relationship between knowledge of drug culture and substance use. Results from a sample of 2,635 middle and high school students indicate that (1) knowledge of drug culture is positively correlated with substance use; (2) drug knowledge is more reliable and coherent in older youth; (3) drug knowledge is unrelated to other kinds of knowledge acquired in school; (4) youth exposed to peers' substance use in school have more drug knowledge; and (5) the earlier young people begin using drugs and alcohol, the more they know about the drug culture. Results suggest that knowledge of the drug culture may be an unobtrusive indicator of substance use problems.This project was made possible by a grant from the Tulsa Psychiatric Center, Tulsa, Oklahoma.Received Ph.D. from University of California at Berkeley in personality psychology.

The authors present a method to separate and preserve stomach contents for forensic purpose. Analysis by "sieve tower" technique is simple and quickly done during autopsy. Solid phases of stomach content are arranged size up and can be stored for subsequent examinations. With the fluid phase drug analysis or microscopic analysis to confirm identy of the foodstuffs may be done. By adding alcohol (70%) enzymatic digestion and bacterial degradation of the stomach content are stopped. 相似文献
