Adult male Sprague Dawley rats were euthanized and placed in a horizontal or vertical (head‐down) position at room temperature, after which brain fluid content was measured by a moisture analysis technique at variable time points. No significant difference in brain fluid content was observed between horizontal and vertical postmortem positions. A significant increase in brain fluid content was demonstrated 3, 6, and 24 h after death, with maximal fluid content observed at 24 h. Specifically, the brain fluid content of control animals was 77.79 ± 0.36%, increasing to 80.05 ± 0.22% at 24 h (p < 0.0001). This study has demonstrated no significant differences in brain fluid content related to postmortem position, suggesting that a head‐down position is not associated with increased brain fluid content or swelling. However, significant temporal increases in brain fluid content after death, most likely related to cerebral liquefaction, occur. 相似文献

Both governments and private for-profit markets have been disappointing in meeting the needs of the African poor for health care. NGO services provide a much more attractive alternative for this clientele, despite the fees they charge. They do so because they represent an institutional solution to the ‘imperfect information’ problem in health care. Through simulations based on data from Cameroon, we demonstrate that if fee-charging NGOs replace the highly subsidised but poorly managed facilities operated by African governments the poor would be better off. Those NGOs that are decentralised in their financial and personnel management are most effective. The politics of making the recommended changes are assessed. 相似文献
