采用微循环显微镜及显微摄影技术,观察超声波对新西兰白兔微循环的影响。提示0.5～1.0W/cm~2的脉冲超声波,对新西兰白兔耳、脑,肠微循环有明显的改善作用,其中以血流速度加快最为显著,其次为微血管的扩张及侧枝循环的建立。机理可能与超声波的机械、温热而产生理化效应有关。本结果为超声波治疗脑血管病提供了实验基础。
The effects of ultrasound on the microcirculation of New Zealand white rabbits were observed by using microcirculation microscope and microscopy. It is suggested that the pulsed ultrasound with 0.5 ~ 1.0 W / cm ~ 2 can obviously improve the microcirculation of ear, brain and intestine in New Zealand white rabbits. Among them, the speed of blood flow is the most obvious, followed by the expansion of microvessels and the establishment of collateral circulation. The mechanism may be related to the physical and chemical effects of ultrasonic mechanical, warm and. The results provide the experimental basis for the treatment of cerebrovascular disease with ultrasound.
