超声波在肌肉骨骼疾病的物理治疗中有应用1，最近的研究结果表明，超声波作为局部合成代谢剂具有潜在的价值2 -4。它被用于检测肿瘤5和胎儿6，而进一步的应用在于根据红细胞速度测量血流速度7，8。超声波在人体组织上的使用越来越多，导致了对可能危害的担忧。必须准确确定安全限值，并研究超声与活组织的相互作用，以便在这些限值内使用超声时可以预测它们。在很大程度上，我们正在研究低强度超声对活组织血液循环的影响，并希望报告一个惊人的发现：红细胞在辐射场中聚集成固定的团块（图1）。
ULTRASOUND has applications in physiotherapy in the treatment of musculoskeletal disorders1, and recent findings indicate a potential value as a local anabolic agent2–4. It is used to detect tumours5and foetuses6, while a further application lies in measuring the rate of blood flow in terms of corpuscular velocity7,8. The increasing use of ultrasound on human tissues has led to concern for possible hazards. It is essential that safety limits are determined accurately and that the interactions of ultrasound with living tissues are investigated so that they can be predicted when ultrasound is used within these limits. Largely in this connexion, we are investigating the effects of low intensity ultrasound on blood circulation in living tissues and wish to report a striking finding: the aggregation of red blood cells into stationary clumps in the radiation field (Fig. 1).
