摘要： The present invention provides drug carriers having high heating efficiency by high-frequency dielectric heating in a state of being selectively accumulated in a target site. The drug carriers each consist of a drug, magnetic fine particles, and a shell containing the drug and the magnetic fine particles. The shell has an outer diameter in a range from 10 nm to 200 nm. The magnetic fine particles having an average particle diameter of d has a standard deviation σ of particle diameter distribution satisfying 0.8d>σ>0.4d. The magnetic fine particles contained in the individual drug carriers generate hysteresis heat due to high-frequency dielectric heating by irradiation of a high-frequency magnetic field.

摘要： The present invention provides an immunoassay technique which enables efficient detection of antigen-antibody reaction with high sensitivity by a magnetic method using magnetic particles and a SQUID magnetic sensor or sensors. A system based on the technique includes a disk-shaped sample holder which holds on a circle a plurality of sample containers for accommodating marked samples, resulting from marking of samples with magnetic particles by antigen-antibody reaction; rotating means for rotating the holder around its central shaft; magnetizing means for magnetizing the marked samples outside a magnetic shield; and a magnetic sensor for detecting, within the magnetic shield, magnetic fields generated from the marked samples which have been magnetized. By rotation of the holder, areas fixing and holding different ones of the sample containers are successively inserted into the magnetic shield, and the magnetization of the marked samples accommodated in first ones of the sample containers and the detection of magnetic fields generated from the marked samples accommodated in second ones of the sample containers are executed in parallel.

摘要： An ultrasound contrast agent composed of at least one kind of low-boiling water-insoluble substance (with a boiling point lower than 37° C.) and at least one kind of high-boiling water-insoluble substance (with a boiling point higher than 37° C.). The former vaporizes to absorb ultrasonic energy upon application of ultrasound, thereby causing the latter to vaporize secondarily, with the resulting bubbles producing an echo image. It is less liable to bumping and hence safe.

摘要： A sensitizer for tumor treatment has a structure such that a lipophilic group and a hydrophilic group are bound to one and the same carbon atom in a compound containing a xanthene dye structure. It is important that the lipophilic group and hydrophilic group are bound to one and the same carbon atom; if they are separated from each other, no sufficient effect is obtained. Thus, the sensitizer possesses both lipophilicity and hydrophilicity. This sensitizer has a function of promoting acoustic cavitation and a function of revealing an antitumor effect and is an agent highly accumulable in tumor tissues. Thus, this sensitizer is highly selective for tumor tissues and enables the treatment of malignant tumor using ultrasound.

摘要： An ultrasonic apparatus for diagnosis and therapy is provided with plural ultrasound probes for generating ultrasound waves for phase shift, diagnosis, and therapy. A first control part causes phase shift in a nano droplet ultrasound contrast agent, while a second control part detects the phase shift of the nano droplet ultrasound contrast agent using ultrasound echo detected by an echo detection device. A difference calculation device calculates a difference of the detected phase shift over time, and a positioning device determines a target position where the difference is produced. A third control part is also provided for exposing a decided target area to the ultrasound waves for therapy.
