We compared the lungs of six drowned and six non-drowned persons over 70 to determine whether there is evidence of acute overinflation in drowning that can be distinguished from senile lung emphysema. All left lungs underwent intrathoracic formalin fixation to preserve their state of insufflation. To assess the effects of lung collapse, all right lungs were sectioned as usual and then immersed in formalin. After histological processing, microphotography and image processing of 12 specimens per corpse, 50 binary images of each specimen were measured by computerized morphometry. Intrathoracic fixation resulted in significantly less tissue area (and more airspace) in the left than in the right lungs of both groups. Comparing both groups' left lungs revealed that the interalveolar septa were thinner and the area occupied by connecting nodes smaller in drowning; these single nodes also tended to be smaller. There was a tendency for less alveolar tissue area per image in drowning than in control lungs and for narrow tissue structures to comprise a higher percentage of both the total tissue area and total tissue perimeter per image. We conclude that there is morphological evidence of acute overinflation even in senile lungs, but this is masked by postmortem lung collapse as suggested by the overlapping values of the right lungs. Support to the diagnosis of drowning among drowned elderly patients can only be available in lungs subjected to intrathoracic postmortem fixation.  相似文献

In rabbits, intracerebrally applied erythrocytes can move with the cerebrospinal fluid along connecting pathways between the subarachnoid space and the cervical lymph nodes. This study compares the time dependency for the degradation of intracerebrally injected erythrocytes in the brain as well as in the cervical lymph nodes. Rabbits were killed at various predetermined intervals after the intracerebral erythrocyte injection. Microscopic and histologic examination of the brain and the cervical lymph nodes revealed the following findings: (1) Erythrophages first appeared in the brain 24 h after the injection; siderophages, 4 days after the injection. Siderophages were still demonstrable at the conclusion of the study, i.e. 240 days after the injection. (2) In the cervical lymph nodes erythrophages were first observed 1 h after the injection; siderophages, 9 h after the injection. Only isolated erythrophages and siderophages were found in the lymph nodes 12 days after intracerebral injection of red blood cells. Later on no erythrocytes or siderophages were observed in the lymph nodes. The findings indicate that non-phagocytized red blood cells arriving at the lymph nodes were ingested by local macrophages. The extremely rapid ingestion and digestion of the red blood cells by lymph node macrophages as well as the possible reasons were discussed.  相似文献

Abstract: The growth in popularity of flying ultralight aircraft and paragliding has been associated with an increased involvement of Emergency Medical Services because of various types of trauma suffered from both inexperienced and skilled individuals. This case presentation reports on a paraglider pilot, who was seen spinning “unusually” rapidly toward the ground, without visible attempts to regain control of the aircraft. Besides the bilateral mydriasis and the absence of any ECG activity, there was a significant swelling of face, lips, neck, and tongue. Upon opening the mouth, a dead bee was found over the tongue, underneath the palate. A fatal anaphylactic shock was the likely cause of death of the pilot while still “in mid‐air.” This case is certainly different from the commonly reported accidents during paragliding. An updated review of the medical literature shows no reported cases of fatal anaphylactic shock during the practice of paragliding.  相似文献

This article deals critically with the call for a comprehensive harmonization of legal rules, against the background of the lessons from the recent financial crisis. Before coming to the topic of harmonization of legal rules, it first briefly deals with the question of why rules are necessary at all, and what the functions of rules are. Then it deals with the lessons from the recent financial crisis for the topic mentioned. The article conducts a kind of cost-benefit analysis of legal harmonization by looking at arguments in favor of and against uniform rules. It shows that not only the arguments in favor have increased after the recent financial crisis, but also the arguments against. It also shows that integration of global markets has not only increased the need for new uniform rules but also decreased the chances of their implementation; and that therefore today it is often better to improve the implementation of current rules instead of laying down new uniform rules.  相似文献
