简介：
Overview
This study investigates the efficacy of low frequency ultrasound in selectively damaging human leukemia cells, both with and without the use of a cholesterol depleting agent. The findings suggest that ultrasound can effectively target malignant cells, enhancing damage when combined with specific agents.
