Alcohol--orally given in concentrations from 1 to 4 g/kg body-weight--leads to a reduction of mast cells in the guinea pig lung. At the same time a minor decrease of histamine concentration was observed. The incompatibility reaction with alcohol after disulfiram intake (DAR) shows an additional degranulation oft mast cells of the lungs and decrease of histamine-content. So far, there seems little difference between the influence of disulfiram alone and the DAR. Besides thrombocytes and basophile leucocytes, the mast cells of the lung are responsible for the release of histamine and serotonine during higher alcohol concentrations and alcohol-disulfiram-reactions. We think that the intolerance phenomena of humans after alcohol--f.e. in form of flush-reaction--is at least partly related to the concomitant influence oft mast cell-substances.  相似文献

The specific gravity and buoyancy of 98 men were calculated at various lung volumes. The data indicated that all subjects would be capable of floating in either freshwater or seawater at total lung capacity. At functional residual capacity, the value approximating the lung volume of a recently dead body, 69% of the subjects would float in seawater, whereas only 7% would float in freshwater. Results of this study indicate that while drowned bodies are more likely to sink than bodies dead of other causes, no conclusion regarding the cause of death can be made on the basis of whether bodies float or sink.  相似文献

Gender and gender-role orientation differences were explored on adolescents' coping with peer stressors. Eighth-grade and ninth-grade public junior high school students (N = 285) completed the COPE, reporting the strategies they recently used to deal with a stressful peer-related situation. Measures of gender-role orientation (Bem Sex-Role Inventory) and demographic information also were obtained. Factor analysis of the COPE revealed 4 distinct coping factors: active, avoidant, acceptance, and emotion-focused. The most frequently reported stressful event was arguments/fights with same-sex friends. Girls reported more arguments/fights with opposite-sex friends. Boys reported more physical fights and threats. Students' ratings of how much the situation mattered were used as a covariate in a MANCOVA to compare coping by gender and gender-role orientation, to control for perceived stressfulness of situations. Significant gender-role orientation differences were found for active, acceptance, and emotion-focused coping.  相似文献

Under the principle of "one country, two systems," Hong Kong's and China's civil services are changing, but they clearly are not converging. The civil service reforms made in Hong Kong and China appear to be heading toward two logical extremes: one toward strengthening political authority over the civil service, and the other instituting greater institutionalization. What appears to be a problem in Hong Kong may be seen as a solution in China. Not only reform problems, but also reform options, are defined in relation to wider political institutions and changing socioeconomic dynamics. The study shows that while some things do need to be uniform, such as loyalty to the state and central government, a great deal of flexibility regarding administrative systems within one country is possible. There can be a modern nation without a truly national civil service.  相似文献
