作者应用PGP9.5与抗S100抗体和高压消毒蒸锅抗原复活技术对4例婴幼儿猝死综合征(SIDS)和3例非心源性死亡对照婴儿心传导系统的神经组织总量进行免疫组化研究。结果:在正常婴儿心传导系统,PGP9.5与S100阳性的神经纤维里不均匀分布,以窦房结最多,房室结次之,希氏束最少;4例SIDS心传导系统的神经组织分布同对照组无明显差异。 相似文献

目的 检测成人心脏中NMDAR1蛋白,观察其分布情况,并探讨法医学意义。方法以12例高坠死亡成人心脏为标本,提取左、右心室和心传导系统(窦房结、房室结、房室束及左右束支)组织作为实验组;取大脑额部组织作为阳性对照组。所取标本各两份,一份采用westernblot技术检测NMDAR1蛋白,另一份采用免疫组化染色法观察NMDAR1在成人心脏中的分布。结果两组中用westernblot均可检出NMDAR1蛋白表达,其强弱程度:脑组织最强,其次为窦房结和房室结,左右心室肌最弱;用免疫组化方法观察,结果在心脏传导系统可见NMDAR1阳性表达,而在心室肌中未见表达。结论成人心脏中存在NMDAR1,主要分布在心传导系统,NMDAR1可能在心脏电生理和病理生理中起作用。 相似文献

178例心源性猝死法医组织病理学诊断分析 总被引:3,自引:1,他引:2
目的探讨心源性猝死(SCD)的病理特点与鉴别要点。方法对四川华西法医学鉴定中心2000—2005年尸检出的178例SCD死亡案例进行回顾性分析,主要对其病因、年龄、诱因及病理改变进行分析。结果本组资料显示冠心病、心传导系统病变、心肌炎、心肌病等在SCD中占有较大比例。冠心病猝死是中老年人SCD的最主要原因,青壮年人SCD的病因以非冠心病为主。如传导系统病变、心肌炎、心肌病。在儿童的SCD中先天性心脏病、传导系统病变及心肌炎占主导地位。结论不同的病因,其病理特点不同,其病理变化是法医学鉴定的主要依据。 相似文献

The authors give the comparative analysis of Russian and foreign forensic medical methods of species character identification of the blood from the stains on the material evidences and bone fragments. It is shown that for this purpose it is feasible to apply human immunoglobulin G (IgG) and solid phase enzyme immunoassay (EIA) with the kit "IgG general-EIA-BEST". In comparison with the methods used in Russia this method is more sensitive, convenient for objective registration and computer processing. The results of experiments shown that it is possible to use the kit "IgG general-EIA-BEST" in forensic medicine for the species character identification of the blood from the stains on the material evidences and bone fragments. 相似文献

法医学是当前司法鉴定中的重要组成部分,其研究内容广泛,具有高度的专业性。随着网络技术的发展、信息资源的增加以及人们法律意识的增强,法医学必然会面临许多新问题,对诉讼证据的要求标准也越来越高。鉴于此,在法医学领域应建立起循证的理念,通过循证的方式在法医学以及相关领域内寻求最合适的解决法医学实务中具体问题的证据,循证不但能够及时解决法医学领域的现行问题,其对于法医学的进步与发展也将具有重大的推动作用。本文综述了循证的基本理论及其在法医学领域的作用,以及循证的途径、方法、证据的评价,并探讨网络环境下法医学循证的应用价值。 相似文献

The history of forensic medicine in times of the Weimar republic and national socialism--an approach
Lignitz E 《Forensic science international》2004,144(2-3):113-124
German Forensic Medicine established the tasks and aims of forensic medicine during the period of the "Weimar Republic" (1919-1933). Since 1925, forensic medicine is part of the medical examination regulation. In times of the 3rd Reich (1933-1945), most of forensic pathologists were influenced by and involved in National Socialism. The special subject of forensic medicine was endangered by the absence of political neutral forensic pathologists. 相似文献

本文从法医学的角度,论述了道路交通事故致伤方式推断的方法、特点以及与涉案人员交通行为方式鉴定、死因分析的相关性,强调了致伤方式推断在事故重建及涉案人员责任认定中的重要性。并以3起真实的道路交通事故为例,阐述了致伤方式推断分析的过程,进一步结合碰撞软件对事故进行计算机仿真研究,再现过程表明致伤方式推断的正确性,初步验证了从致伤方式推断入手分析涉案人员交通行为方式、死亡原因的可行性;同时指出对于致伤方式不明确的道路交通事故,可通过事故遗留的制动轨迹、速度等进行计算机模拟研究,对于致伤方式推断具有一定的参考价值。 相似文献

The supplementary designation "criminalistics" in the title of certain forensic medical institutes in the first half of this century is to be regarded as a reaction to faulty developments in our specialty, which almost led to the elimination of forensic medicine as an independent scientific discipline in the 1960s. The ability to think in terms of criminalistics and the corresponding working procedures has always been a crucial precondition for the forensic physician, since forensic medicine is the application of medical knowledge for juridical purposes. Forensic medicine originated with the appraisal of cases of violent death by doctors, i.e., reconstruction of the facts in the case. To use the term "criminalistics" in the form of a supplementary designation is thus not required. An attempt is nevertheless made to define "medical criminalistics" as a small but important component of criminalistics. They are subdivided into two phases: the first part begins at the scene of the crime or the place of discovery (local evidence). Here, the trained eye of the forensic physician is indispensable to the criminal investigation department and the prosecutor. Medical criminalistic thinking and working procedures continue at the autopsy. Here, forensic autopsy differs from that practiced by the pathologist. Without knowledge of the situation at the discovery location, the forensic physician runs the risk of not recognizing facts that are important for reconstruction and thus becoming a "destroyer of clues". The second part of medical criminalistics is the actual detection of medical clues, i.e., the investigation of medical clues with special methods, including histological and toxicological investigations.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Computerizing of medicine is expected to increase very rapidly in the next few years. This will bear new questions for forensic judgement. We report a case and our expert opinion concerning the use of a very simple computer program at a private hospital to obtain comments on laboratory findings. Furthermore we discuss questions we consider to be of importance for forensic judgement in this field. 相似文献

Scientists submitting expert opinions within the legal system are expected to be knowledgeable in the forensic aspects of their particular science, as well as to be ethical and unbiased. Scientists are seldom able to decline a request to provide an expert opinion in their field, even when their forensic expertise is minimal. The competence of scientists providing expert opinions in forensic cases is reviewed here. Three examples of the perils of uninformed "expertise" in forensic biology, medicine and anthropology are presented. 相似文献
