In 90 forensic autopsies (Craniocerebral injury, gunshot, stabbing, blow, strangulation, etc.), semithin sections of great arteries were prepared from around 770 Epon blocks and checked for vital reactions at the mural and intimal ruptures. In 21 cases in which death had occurred immediately or soon after the trauma, with three exceptions, there was a subsequent electron microscopic investigation. In all six mural ruptures and in five of ten intimal ruptures, thrombocyte aggregates were found at the rupture margins. In five intimal ruptures, the possibility of the occurrence of preparations injuries had to be considered. In five cases, the results of the histological study were negative. The success rate is limited in principle in such a screening test since there are technical difficulties in preparing serial sections on long vessels. Death was rapid and the thrombocytes were observed to adhere to the injured wall sites immediately after the trauma. The "thrombocyte sign" is thus of substantial importance as the earliest local vital reaction. In two control cases (strangulation), thrombocyte aggregates were found at intimal ruptures of the basilar artery, which were regarded as the results of stretching via the vertebral arteries during attacks to the neck. The healing processes of intimal ruptures and traumatic medial necrosis in incomplete ruptures occurring later in life are discussed. Even if a cadaver is a few days old, the histological findings at the level of the thrombocytes can be evaluated.  相似文献

The writings of Sir Bernard Spilsbury: Part I   总被引:1,自引:0,他引:1  
This is a two-part historical feature, highlighting the rare writings of Sir Bernard Spilsbury, the recognized leader of British forensic medicine in the first half of the 20th century. Parts I and II were compiled from the publications of the Medicolegal Society of Great Britain, where Sir Bernard Spilsbury served as President in 1933. Although his profile was presented previously in this Journal (vol. 2, no. 2, 179-182, 1981), it is felt that much of Sir Bernard Spilsbury's personality comes out in his writings and recordings of his speeches in the Medicolegal Society publications. Part I includes his lecture on "The Medico-Legal Significance of Bruises," presented before the Medicolegal Society in 1938; and a short case report read before the Medicolegal Society in 1924. The subject of the case report was sudden death from inhibition. Part II will contain two papers from the Medicolegal Society publications.  相似文献

A split-ballot experiment shows that, when people are asked how interested they are in following political campaigns, their response depends not only on the order in which the question is asked, but also on the broader electoral context in which it is posed. When asked how interested they were in following the political campaigns immediatelyafter a question about whether or not they voted in the (1982) election, people were more likely to think they were interested in the campaign, especially if they claimed to have voted, than if they were asked about it immediatelybefore the question on whether or not they voted. This order effect, however, appears to depend onwhen the questions are asked. If asked within a few weeks after the election, there is little or no order effect. But later, as the memory of the campaign fades, the order of the questions makes a sizable difference in the results. This order effect also seems to be more pronounced among better-educated respondents, suggesting that they are more likely to feel pressured by a social norm to vote and to express an interest in political affairs, not only in real life, but in the survey interview as well. The paper concludes with a brief discussion of the implications for the design of the interview schedule used in the American National Election Studies.The research reported in this paper was supported by a grant from the National Science Foundation (SES81-11404).  相似文献
