Microparticles containing active ingredients, agents containing these microparticles, their use for ultrasound-controlled release of active ingredients, as well as a process for their production

摘要：

The invention relates to new microparticles containing active ingredients, which contain at least one gas or a gaseous phase in addition to the active ingredient(s), agents containing these particles (microparticulate systems), their use for ultrasound-controlled in vivo release of active ingredients, as well as a process for the production of particles and agents.

摘要（中）：

本发明涉及含有活性成分的新的微粒，其除了活性成分之外还含有至少一种气体或气相，含有这些颗粒的试剂（微粒体系），它们用于超声控制体内释放活性成分成分，以及生产颗粒和试剂的方法。
