常压模拟高住低练对大鼠红细胞形态学特征的影响

本研究探讨了常压模拟高住(海拔3000m)低练对大鼠红细胞形态学特征的影响。结果表明:低住安静组大鼠MCH低于其他三组大鼠,具有显著性差异(P<0.05);低住安静组平均红细胞血红蛋白浓度(MCHC)和常压高住安静组没有明显的差别,但低住低练组的MCHC明显地高于常压高住低练组,具有非常显著性差异(P<0.01)。结论:常压模拟高住低练时,红细胞血红蛋白合成减少,应加强营养物质铁、维生素B12、叶酸的补充。

A nation at risk: The economic consequences of neglecting career development

Conclusion Computer-based career systems should be the focal point of popular, and effective career development initiatives which are of tremendous benefit to individuals. Such initiatives also have the potential to significantly reduce public expenditures and enhance the nation's competitive position internationally. The key lies in helping people understand that we can no longer afford to neglect the career development needs of Americans.I am most grateful for this opportunity to share my thoughts with you. I encourage you to promote the use of computer-based career systems by defining their benefits in economic terms. However, be sure you can prove your system does more than simply entertain its users, or leave them with extensive computer printouts.Phillip S.
