摘要:
Provided is a method suitable for industrial-scale production of a dispersion in which nano-sized particles are dispersed. Specifically, a method for producing a nanoparticle-in-oil dispersion in which fine particles made up of a solid component, an aqueous liquid component or a mixture thereof are dispersed in an oil phase, includes: (1) a step of preparing a W/O emulsion-type precursor in which an aqueous phase in the form of droplets of an aqueous solution having a water-soluble substance dissolved therein is dispersed in an oil phase; and (2) a step of boiling the aqueous phase of the W/O emulsion-type precursor, to obtain a nanoparticle-in-oil dispersion in which the fine particles are dispersed in the oil phase.

This invention provides an agent for inhibiting production of hepatitis C virus with notable anti-HCV activity and without side-effects. The agent comprises a proanthocyanidin polymer composition illustrated in the following the general formula (1), wherein R1 is hydrogen or hydroxyl, R2 is hydroxyl, R3 is hydrogen when R1 is either hydrogen or hydroxyl, but R3 is possibly hydroxyl when R1 is either hydrogen or hydroxyl to the extent that both R1 and R3 being hydroxyl is at most 40 percents in the proanthocyanidin polymer composition said units of flavan-3-ol being bonded each other in any one of three patterns as follows; (i) a bond between carbon at the position 4 and carbon at the position 8, (ii) a bond between carbon at the position 4 and carbon at the position 6, (iii) a bond between carbon at the position 4 and carbon at the position 8, and between carbon, at the position 2 and oxygen at the position 7.
摘要:
In a solder paste which is a mixture of a flux and low melting point metal particles, low melting point metal fine particles manufactured by a conventional method or apparatus therefor include particles having widely varying particle diameters. Accordingly, the solder paste could not completely fill the minute holes in a mask for application to minute solder portions by printing, or mask removability was poor. According to the present invention, a mixture of a heat resistant continuous phase liquid and coarse metal particles in molten state is passed through a porous membrane to form the coarse low melting point metal particles into fine particles with a predetermined diameter. An apparatus according to the present invention comprise a porous membrane between a heating and dispersing mechanism and a cooling mechanism, and a pressure vessel connected to the heating and dispersing mechanism for applying a high pressure to the heating and dispersing mechanism.

An object of the present invention is to provide a method of preventing or treating liver disease, particularly non-alcoholic fatty liver disease, hepatic fibrosis, cirrhosis, or liver cancer. The present invention is directed to a method of preventing or treating liver disease comprising administering to a patient in need thereof an effective amount of an osteoactivin-like protein or a fragment thereof having liver disease-suppressing activity similar to that of osteoactivin or a gene comprising a DNA encoding such a protein or fragment.
