【摘要】 目的　研究次声对大鼠血液流变特性的影响 .方法　使用频率 8Hz,强度为 90 d B与 12 0 d B的次声每日对大鼠作用 2 h,观察血液流变特性的变化 .结果　 12 0 d B作用 7d与 90 d B作用 14d后导致了血细胞比容、全血高切粘度、全血低切粘度等血液流变指标改变 ,而 12 0 d B作用 14d,90 d B作用 2 8d后这些变化的指标又都恢复 .结论　一定范围内的次声作用可引起强度相关的血液流变学改变 ,而且这些改变是可恢复的 .更多还原

【Abstract】 AIM To study the effect of infrasound on the hemorheology of rats. METHODS Rats were radiated for 2 hours every day by the infrasound of 8 Hz 120 dB and 90 dB and its hemorheological index were measured. RESULTS We found that 7 d of 120 dB and 14 d of 90 dB could make Hct, whole blood high shear rate viscosity and whole blood low shear rate viscosity change ( P <0.05) and after 14 d of 120 dB and 28 d of 90 dB all of the changes disappeared. CONCLUSION Infrasound can make the hemorheological performance change, which are dependent on the frequency and the strength of the infrasound, and these changes are recoverable.更多还原
