摘要:
The ultrasonically-induced in vitro cell damaging effect of fluorine-containing anthracycline derivative (FAD104) was investigated. Sarcoma 180 cells suspended in air-saturated PBS were exposed to ultrasound for up to 60 s in the presence and absence of FAD104. The rate of inducing cell damage with ultrasound was doubled with 80 mu M FAD104, while no cell damage was observed with FAD104 alone. This enhancement was significantly inhibited by histidine, which may suggest a sonochemical mechanism. Published by Elsevier Science Ireland Ltd.
