Post mortem tissue samples from various human organs (skin, muscle, liver, kidney, brain) were stored at room temperature for a period of one year. During this time the samples were regularly histologically tested. Without any pretreatment of the samples a histological preparation and identification was no longer possible after only a few hours. By the use of a rehydration solution consisting of absolute ethanol (30 ml), aqua dest. (50 ml) and 0.2 M phosphate buffer pH 7.0 (20 ml) a reconstitution and identification was again possible. Further immunhistochemical examinations were also unaffected by the solution. The use of microwave stimulation allowed a reduction of the rehydration process from 24 hours to only 4 hours.  相似文献

A reversible technique is presented in which the root morphology of missing teeth in skeletonized human remains can be reconstructed for the purpose of radiographic comparison and postmortem identification. In this technique, which is based upon pilot studies with skeletonized mandibles of archival remains, the alveolar socket walls are sealed with a coat of cyanoacrylate cement and injected with a mixture of vinyl polysiloxane and barium sulfate. Radiographs are produced with the radiopaque mixture in place, which highlights the antemortem morphology of the roots. Subsequently, the impression material is removed, resulting in no gross alteration of the evidence. The radiographs made with this technique, as well as the impressions, can be stored for later use at a trial or pending the discovery of antemortem dental evidence.  相似文献

Between 1987 and 1989 there were approximately 5,000 cases of fatal and injury-sustained road traffic accidents, of which 2.3-3.0% were alcohol related (blood alcohol levels greater than the legal limit of 80 mg% ethanol). The offenders of alcohol-related accidents are mostly Chinese (> 79%), male (> 98%), and more often 30-40 years old. The majority of the alcohol-related accidents (> 74%) took place between 8 P.M. and 4 A.M. in fine weather and light traffic. Rear-end, head-on, and side-on collisions comprised > 60% of all the alcohol-related accidents, and losing control of vehicles approximately 30%. Drunken driving cases for the same period that were not accidents showed a number of characteristics similar to those for accidents. In Singapore, motorcycle riders and pedestrians are more prone to road fatality than other road-user groups. International comparisons of road fatalities per 100,000 population gave Singapore one of the lowest accident rates (8.1-8.4) as compared with countries such as Australia, the United Kingdom, the United States, New Zealand, Canada, and Japan.  相似文献

In the 14-year period from 1976 to 1989, there have been 174 homicide victims in the Auckland colonial area. Data accessed from autopsy and police reports show that victims of marital conflict, family dispute, and arguments developing between nonmarried couples made up the largest proportion of homicide cases. Stabbing and assault with a blunt weapon were the most common causes of death. The data also show that homicide is relatively uncommon in Auckland in comparison with other cities of similar size.  相似文献

Over the past fifteen years the national government in the Federal Republic of Germany has animated the political debate about rising health care expenditures. However, it has only provided health policy leadership by shifting the burden of financing health and medical care to others. This paper presents three cases that illustrate the political and institutional constraints inherent in the German policy process that limit the proposal and implementation of appropriate policy solutions to rising health care costs. Cost controls have been inhibited because of the near-universal entitlement of national health insurance, the access all social groups have to advanced medical care, and policies targeted at providers rather than users of health services. The paper also underscores the past and future importance of regional policy coalitions in shaping national health policy.  相似文献

The distribution of Tf phenotypes in the population of Padua was investigated by ultrathin-layer isoelectric focusing. In our sample (n = 618) nine phenotypes, Tf C1, C2, C3, C3?1, C2?1, C3?2, C1B, C2B and C1D, were observed and the following frequencies calculated: TfC1 = 0.77837; TfC2 = 0.1804; TfC3 = 0.03641; TfB = 0.0040; TfD = 0.0008. These gene frequencies have been compared to those found in other populations. Analysis of 101 mother-child pairs was in agreement with an autosomal codominant mode of inheritance.  相似文献

Do city governments generally behave in keeping with the assumptions underlying the incremental model when they allocate their resources among competing activities? That is to say, do they try to maintain everyone's historical “fair share” of the budget in order to minimize disputes among rival participants in the decision process? Earlier studies have lacked sufficient data to address this question. However, with data from 105 West German cities, the present study is able to provide an answer. The resource allocation behavior of many of those cities seems to conform with the incremental model's assumptions. Yet for other cities, major changes in expenditure patterns from one year to the next are common. The differences in the variability of expenditure patterns across the cities studied are far from random. They are systematically associated with certain characteristics of the municipal environment. These associations, in turn, offer plausible hints about the process that leads to change in cities' spending patterns.  相似文献
