In malignant hyperthermia, myophosphorylase reaction shows characteristic changes that take place within minutes: (1) a generally strongly weakened reaction; (2) numerous negatively reacting fibres; (3) frequently, fibre sections that show spotty and/or striatal weak or negative reactions and fibre sections with strong striatal reactions with relatively narrow sarcomere spacings (a "sign of hypercontraction"). Obviously, the morphological findings that show characteristic "striated fibres" are typical of the malignant hyperthermia syndrome! It is important to note that the muscular fibres showing such changes are, as a rule, inconspicuous when using other stains and reactions. These pathological myophosphorylase reactions were observed in five deceased patients (one independently of anaesthesia after an extended walk) and in 19 pigs (18 times after halothane testing and once in an experimental animal with clinical evidence of the presence of malignant hyperthermia). These reactions were not noted in pigs with negative halothane reactivity or prior to halothane testing. They were also not seen in a large number of very different healthy and diseased control and reference cases from our biopsy and autopsy material. Myophosphorylase reaction enables convincing demonstration of malignant hyperthermia, past or present. Hence, it is possible to elucidate puzzling deaths or verify apparently clear death occurring during or subsequent to anaesthesia or simply following stress ("human stress syndrome"). Many of these deaths doubtlessly escape the attention of clinicians using the usual morphological examination methods. However, the reaction cannot be used to identify potential victims. 相似文献

Minimal attention has been focused on difficulties for youth in residential care regarding building healthy dating relationships, despite the significant risks to this group of adolescents. This study provided a unique opportunity to conduct focus groups with youth in residential care on issues surrounding dating relationships. The majority of youth feedback centered on the themes of desiring support developing relationship boundaries, establishing trust in relationships, understanding the consequences of sexual activity, and having real world examples regarding dating relationships. The data were examined for differences between the genders and recommendations for next steps provided. 相似文献

Environment protection in Austria is still carried out mainly by public authorities. This article focuses on preventive measures. It takes up the approval of new or rebuilt plants according to the Trade Act as an illustration for a considerable number of similar procedures. Although there is an ongoing discussion of the advantages and disadvantages of those procedures, no attempt has been made yet to examine their contents from a strictly economic perspective. Therefore, the article extracts the economic consequences from the wording of the law and examines whether they can give rise to efficient environment protection, taking into consideration the goals and constraints of all the participants in the negotiations. It is found that in principle the procedure allows for efficient solutions, despite the disadvantages, which are frequently observed in the course of its application. Moreover, it is argued that some features of the procedure, such as the selection of an appropriate techn ology on behalf of an applicant as well as negotiations with the potential pollutees have not yet been interpreted correctly. An assessment against more market-orientated measures, which are favored nowadays, ought to take into consideration that they generally cannot be implemented without support from the government. 相似文献

In diesem Beitrag wird der Frage nachgegangen, unter welchen Umst?nden der Staat aus der Perspektive der ?konomie legitimiert
ist, gegen bettelnde Menschen vorzugehen. In der ?ffentlichkeit hat die Frage vor allem wegen des Verdachts neue Nahrung erhalten,
dass Betteln organisiert erfolge und von Personen betrieben werde, die sich teilweise sogar illegal in ?sterreich aufhalten. 相似文献
