A 35-year-old multipara died suddenly of a pulmonary embolism about 12 h after delivery. The morphological features and the entry site of the emboli into the circulation suggested that they were decidual cells. Intact decidual cells accounted for only a minority of the emboli: the great majority were cells that had lost their nuclei and/or had been fragmented. The presence of embolized areas, accompanied by fibroblasts and newly formed capillaries, suggested that the embolization process had started before the beginning of labor. However, no symptoms suggesting embolism had been recorded on the clinical chart.  相似文献

The genetic polymorphism of serum orosomucoid (ORM) was studied in 168 unrelated German individuals using isoelectric focusing followed by immunoprinting. Two new alleles, tentatively designated ORM1*14 and ORM2*13, were identified. The method was successfully applied to demonstrate ORM1 types in dried bloodstains. Each type of ORM1 was also correctly determined in bloodstains heated at 130 degrees C for 30 min. The results indicated that ORM1 is a new powerful genetic marker system for the grouping of bloodstains.  相似文献

The pathomechanism of carbon monoxide (CO) poisoning was studied by means of cardiopathological and neuropathological investigations in experimental CO intoxication. It has been shown that besides CO-hemoglobin association, the binding of CO to cytochromes is a significant factor. The latter is thought to be responsible for the cytotoxic phenomena. Combined ultrastructural and cytochemical studies have enabled differentiation between toxic, hypoxic, and mixed alternations.  相似文献

This series of studies extended procedural justice research to the informal domain of dispute resolution in intimate same-sex friendship. The first study identified the types of disputes that occur between friends and the concerns that friends have when choosing dispute resolution procedures. Seven dispute types and 11 procedural criteria were found relevant to dispute resolution in friendship. Study 2 assessed the importance of procedural criteria for resolving several dispute scenarios. As expected, ratings of criterion importance were affected by subject and disputant sex. Females rated four criteria as more important than did males, and one criterion was rated as more important in disputes involving a male and a female than in disputes involving two females. The importance of procedural criteria was also influenced by the type of dispute, but this effect was qualified by an interaction with the dispute version. It was suggested that the importance of procedural criteria is generally defined by the context of friendship and specifically defined by the dispute topic. In Study 3, the relations among subject sex, traditional fairness variables, and criterion-based measures of process control were examined. Consistent with studies in other domains, process control predicted procedural justice, and decision control predicted distributive justive. Moreover, the hypothesized fair process effect emerged as a function of speed, a criterion-based measure of process control.  相似文献

Professions are guided by codes of ethics to aid them in performance of their duties and to ensure maintenance of high standards of conduct. Police officers are faced with a maze of obligations in the performance of their official duties. The “Law Enforcement Code of Ethics” and “Canons of Police Ethics” were created to make explicit the conduct considered appropriate for police officers and to guide them in the performance of their duties.This study investigates how police officers in several police agencies view their professional ethics. Some of the broader questions examined in the study are the following: Do police officers have a clear understanding of the “Law Enforcement Code of Ethics” and the “Canons of Police Ethics?” Do they feel constrained by agency, societal, or other factors from behaving professionally? Do they consider their ethics adequate to guide professional conduct, and are they willing to abide by the principles? The responses indicate reliance on personal ethics in situations where standard police ethics are not clear, and suggest the need for further research in police ethics.  相似文献
