Abstract: The invention prevents or treats a tumor, inhibiting tumor growth and malignant progression by providing an antitumor agent containing a treated SOD as the active ingredient, especially a melon SOD coated with gliadin. The invention also applies to a method of preventing or treating the tumor.

Abstract: A strong pressure and a strong shearing force are exerted to a mixture, constituted of two kinds or more of powder materials including a drug powder, while causing the mixture to pass between a press section (26) of a press head (24) and a receiving surface (25) of a cylindrical rotator (23), thereby combining the drug powder with the other powder material. For example, at least one of a drug and a biocompatible polymer is made into a nano particle whose average particle diameter is less than 1000 nm, and the nano particle is made into a composite in accordance with a dry mechanical particle combining method, so as to form a polymer nano composite particle. Thus, it is possible to produce a composite particle, which contains a drug under a stable condition, in a short time, and it is possible to remarkably improve its handling property without losing advantages of the nano particle.

Abstract: A manufacturing method of a superconducting material having the steps of: milling and mixing a powderly primary material in a casing of a dry type milling mixer; heat-processing the primary material obtained from the milling/mixing step; and again milling and mixing the primary material obtained from the heat-processing step in the casing of the milling mixer so as to obtain a secondary material. The milling mixer includes a casing for holding the primary material therein and friction-pulverizing mixing elements for frictionally pulverizing, stirring and mixing the primary material inside the casing. The two milling/mixing steps are effected under a high-speed rotation of the casing where a centrifugal force resulting from the casing rotation presses the primary material against an inner surface of the casing and a layer of the material formed on the surface is frictionally pulverized, stirred and mixed by the friction-pulverizing mixture elements.

Abstract: An apparatus for treating a particulate material comprising a casing defining a treating chamber and rotatable at high speed to produce a centrifugal force for pressing the material in the casing against an inside wall surface of the casing. Treating members such as pulverizing members are disposed in the casing for revolution relative to the inside wall surface of the casing. The treating chamber has a discharge opening for permitting overflows of the material under treatment. The discharge opening is disposed adjacent a center of rotation of the casing, and a limiting device is provided adjacent the discharge opening for limiting the overflows of the material under treatment. A classifier is provided to communicate with the discharge opening of the treating chamber for receiving treated material.

Abstract: An apparatus for classifying particles into fine particles and coarse particles by a classification standard particle size which is determined by selecting a rotational frequency of a classifying rotor. The rotational frequency is derived from an equation stored in a computer and the rotor is automatically maintained at the rotational frequency thus derived.

Abstract: An apparatus for classifying particles comprising a main body having a fine particle outlet and a coarse particle outlet, a classifying fan wheel disposed within the main body, and a first gas inlet channel for supplying the particles to the interior of the main body along with a gas stream. The apparatus further includes a gas passing member having a large number of gas inlets opened toward the direction of rotation of the fan wheel, and a second gas inlet channel for supplying a gas stream to the space between the gas passing member and the inner wall surface of the main body.
