    • Disclosed are suspensions of gas microbubbles immobilised within a frozen aqueous carrier liquid comprising usual additives and stabilisers, in which the carrier liquid is a physiologically acceptable, the immobilised gas microbubbles are microbubbles bound by an evanescent envelope or a tangible membrane. The suspensions, when in liquid form, are injectable and useful as a contrast agents in ultrasonic imaging of blood pool and tissue of living beings. The gas microbubbles are immobilised within the carrier by freezing a suspension of microbubbles with average sizes below 50 .mu.m, preferably below 10 .mu.m and more preferably between 2 .mu.m and 8 .mu.m, to a temperature between -1.degree. C. and -76.degree. C. and maintaining this temperature for prolonged periods of time. The microbubbles may be stabilised by a surfactant such as a lamellar phospholipid or may comprise a membrane made of synthetic or natural polymer or protein. A method of cold storage of microbubble suspensions as well as their use is also disclosed.
    • 公开了固定在包含通常的添加剂和稳定剂的冷冻含水载体液体中的气体微泡的悬浮液,其中载体液体是生理上可接受的,固定化气体微泡是由ev逝包膜或有形膜结合的微泡。 当液体形式时,悬浮液是可注射的,并且可用作血液池和生物组织的超声成像中的造影剂。 将气体微泡固定在载体中,将平均尺寸低于50μm,优选低于10μm,更优选在2μm和8μm之间的微泡悬浮液冷冻至-1℃至-1℃的温度, 76℃,并保持该温度较长时间。 微泡可以通过表面活性剂如片状磷脂来稳定,或者可以包含由合成或天然聚合物或蛋白质制成的膜。 还公开了微泡悬浮液的冷藏方法及其用途。
