摘要: The effects of low-intensity ultrasound (US) on biological systems have been investigated extensively; however, the effects of ultrasound stimulation on endothelial cells were rarely studied. In this study, 1 MHz, pulsed 1:4, and four different spatial-average temporal-peak intensities (0.5. 1.0, 1.6, and 2 W/cm(2)) of ultrasound were used to stimulate endothelial cells for 10 min per day. The results showed that ultrasound (intensity 1.6-2.0 W/cm(2)) treatment after 6 days enhanced the nitric oxide (NO) and Ca2+ release from the endothelial cells but did not promote cell growth. In addition, ultrasound stimulation changed the cellular morphology and orientation, and increased extracellular matrix secretion from endothelial cells. (C) 2004 Elsevier B.V. All rights reserved.
