Abstract: Disclosed are a targeting magnetic nanosphere preparation capable of diagnosing and treating tumors in mammals and a method of manufacturing the same. The smart magnetic nanosphere preparation contains magnetic nano-sized iron oxide nanoparticles, which can be detected by magnetic resonance imaging (MRI), as a core material. The core material is encapsulated in a size of tens to hundreds of nanometers allowing particles to penetrate into deep areas of biological tissues using a biodegradable polymer having high affinity for biological tissues. The formed capsules are surface-modified with an antibody specific to a specific tumor. The smart magnetic nanosphere preparation can effectively diagnose tumors, as well as treat tumors because it has an antibody to a specific tumor.

Abstract: The present invention provides a thermosensitive liposome which permits temperature-sensitive drug release and exhibits variable release temperatures. The process for preparing a thermosensitive liposome of the invention, comprises a step of coating the surface of a liposome with a copolymer of N-isopropylacrylamide/octadecylacrylate/acrylic acid, by the addition of the copolymer to the liposome suspension in a weight ratio of 1:0.05 to 1:0.2 (liposome:copolymer), and the incubation of the polymer-liposome suspension at a temperature range of 0.degree. to 10.degree. C., for 10 to 14 hours. The thermosensitive liposome of the present invention is able to control the temperature of drug release at a temperature range of above 28.degree. C., preferably at 28.degree. to 36.degree. C., depending on the acrylic acid content in the copolymer of N-isopropylacrylamide/octadecylacrylate/acrylic acid.

Abstract: A panel testing apparatus for measuring the curvature of an inner surface, the thickness of an edge portion, and the thickness of a center portion of the panel comprises a lifting device for accepting and transporting the panel to a testing position, and a panel supporting device for maintaining the panel in a predetermined position during testing. The apparatus comprises a panel inner curvature measuring device, edge thickness measuring device, and a center thickness measuring device, each of which using one or more linear variable differential transformers for the purpose of providing panel measurement data.
