Methods of and apparatus for preparing temperature activated gaseous precursor-filled liposomes are described. Gaseous precursor-filled liposomes prepared by these methods are particularly useful, for example, in ultrasonic imaging applications and in therapeutic drug delivery systems.
Gas, gaseous precursors and perfluorocarbons are presented as novel potentiators for ultrasonic hyper-thermia. The gas, gaseous precursors and perfluorocarbons which may be administered into the vasculature, interstitially or into any body cavity are designed to accumulate in cancerous and diseased tissues. When therapeutic ultrasonic energy is applied to the diseased region heating is increased because of the greater effectiveness of sound energy absorption caused by these agents.
本文描述了制备温度活化的气体前体填充脂质体的方法和装置。通过这些方法制备的充满气体前体的脂质体尤其适用于超声波成像应用和治疗药物输送系统。
介绍了气体、气体前体和
全氟化碳作为超声波高热的新型增效剂。气体、气体前体和
全氟化碳可被注入血管、间隙或任何体腔,旨在积聚在癌症和病变组织中。当治疗性超声波能量作用于病变区域时,由于这些制剂能更有效地吸收声能,因此会增加加热效果。
