The authors observed the edges of skull fractures under the scanning electron microscope. Many microfractures can be found along the main fracture lines. The width of the microfractures varies from 5 to 100 microns. They may be located either in the external compact bone or between the outer compact bone and dipl?e, or in the dipl?e. Those within the dipl?e form transverse, longitudinal or spiral fractures of bony trabeculae. Collagenous fibre bunches in the bony matrix may be divided or broken and the different layers of collagenous fibre may be separated. The blood vessels inside the skull may be crosscut or longitudinally torn by the fracture lines. Sometimes the torn blood vessels may be drawn out of the Haversian canals. In antemortem fractures, the fibrin networks and red blood cells can be easily found in the depths of those cracks. The possible mechanism of formation of the microfractures and the possibility of differentiation between ante- and post-mortem fractures are discussed. 相似文献

A modified Poley's acid fuchsin-methyl green stain was used to demonstrate ligature marks in tissues taken at autopsy. This stain was compared in 30 cases with haematoxylin-eosin, Mallory's trichrome and Ogata's picro-indigocarmine stains. Using the modified Poley method, it was possible to demonstrate the compression mark in corpses even when post-mortem changes were advanced. The method was found useful in evaluating the cases when the force used was minimal or when the mark was atypical using the usual haematoxylin-eosin method. 相似文献

Widespread fatal massive bone marrow embolism of the coronary and the pulmonary arteries are described in a 71-year-old man with a respiratory disease. Cardiac massage was carried out during the cardiac arrest. In autopsy findings there were no fractures of the ribs or the sternum. The authors suggested that the cardiac massage was the most important predisposing factor for the bone marrow embolism. 相似文献

Michael Zürn 《Journal of Political Ideologies》2016,21(3):280-301
Economic, cultural and political systems formerly bounded by the borders of nation states are increasingly globalized. Politicians, civil society and other societal actors engage in publically debating issues related to globalization. Whether conflicts consolidate to form a stable cleavage depends among other factors on the extent to which they become ideologically underpinned. As the basis for such an underpinning, we identify philosophical debates about justice between globalists and statists and between universalists and contextualists as raw material that political entrepreneurs active in the public sphere can draw upon. On this basis, we identify four major bones of contention that could provide the core of such ideological underpinning: the permeability of borders; the allocation of authority between levels; the normative dignity of communities; and the patterns of justification. One ideal typical combination of those four components can be labelled cosmopolitanism—combining arguments from globalists and universalists; another communitarianism, combining statist and contextualist arguments. The more these two ideal types feature as political ideologies in public debate, the more do debates about globalization solidify into a new cleavage. We develop a conceptual framework which can subsequently be used in support of empirical research analysing the ideological foundations of globalization conflicts. 相似文献
