摘要: The invention relates to ultrasound contrast agents comprising vesicles comprising a protein capable of formation of gas-containing vesicles, wherein the vesicles contain gas which comprises sulphur hexafluoride or a low molecular weight fluorinated hydrocarbon. These contrast agents exhibit stability in vivo upon administration so as to permit ultrasound visualization while allowing rapid subsequent elimination from the system.

摘要: Separation of target material from a liquid sample is achieved by coupling the target to targetable encapsulated gas microbubbles, allowing the microbubbles and coupled target to float to the surface of the sample to form a floating microbubble/target layer, and separating this layer from the sample. In a positive separation process the microbubbles are then removed from the target, e.g. by bursting. In a negative separation process target-free sample material is recovered following separation of the floating layer. The method may also be used diagnostically to detect the presence of a disease marker in a sample. Novel separation apparatus is also described.

摘要: The invention provides a method of detecting myocardial ischemia in a human or a non-human body, said method comprising administering to said body a physiologically acceptable manganese complex or salt thereof, subjecting said body to a magnetic resonance imaging procedure capable of generating images with time intervals of less than 0.5 seconds and thereafter providing a series of images of the myocardium of said body whereby to identify regions of abnormal blood flow. The method in accordance with the invention is of use not only in detecting myocardial ischemia, but also in discriminating between reversibly and irreversibly injured myocardial tissues, thereby providing important information about myocardial viability, e.g. during or following a severe heart attack or coronary occlusion. The method of the invention also provides an effective means of monitoring reperfusion of the myocardium.

摘要: Oil-in-water emulsions in which the oil phase comprises condensed or dissolved oil-soluble gas/fluid or gas precursor are useful as ultrasound contrast agents. Such products contain insignificant amounts of free gas bubbles or microbubbles in their stored form and exhibit good stability, but may be designed to promote rapid microbubble generation immediately before or upon administration.
