Abstract: The present invention relates to a pharmaceutical composition and a health functional food composition for prevention, treatment or amelioration of diabetic complications or angioedema containing a mixed extract of Hedera helix leaves and Coptis chinensis as an active ingredient. More specifically, the present invention relates to a pharmaceutical composition and a health functional food composition for prevention, treatment or amelioration of diabetic complications or angioedema further containing an extract of Rheum palmatum, Puerariae radix, Ginkgo leaves, Cassiae semen, blueberry, bilberry, raspberry, or grape seeds as an active ingredient, in addition to the mixed extract of Hedera helix leaves and Coptis chinensis.

Abstract: The present invention relates to a pharmaceutical composition for the prevention and treatment of diabetic complications comprising the extract of Homonoia riparia Lour. or the fraction thereof as an active ingredient. More particularly, the extract of Homonoia riparia Lour. or the fractions thereof of the present invention can inhibit the activity of aldose reductase and the generation of the advanced glycation endproducts, the index of diabetic complications, and have powerful activity of inhibiting diabetic complications with brining the anti-cataract, anti-retinopathy, and anti-neuropathy effect, and have the activity of anti-oxidation as well, so that they can be effectively used as an active ingredient of a pharmaceutical composition for the prevention and treatment of diabetic complications.

Abstract: The present invention provides a novel biphenyl compound or pharmaceutically acceptable salts thereof, methods for preparing the same, and pharmaceutical compositions for preventing or treating diabetic complications containing the same as an active ingredient. Novel biphenyl compounds, according to the present invention, effectively suppress generation activity of advanced glycation end products, which cause diabetic complications and are a criterion for evaluating the effectiveness of a treating agent for diabetic complications, and show an excellent therapeutic effect on retina blood vessels, increased occludin, and decreased angiogenic growth factor in actual diabetic retinopathy induced retina. Thus, novel biphenyl compounds according to the present invention can be used effectively as an active ingredient in compositions for preventing or treating diabetic complications such as diabetic retinopathy.

Abstract: An international messaging system for transmitting a short message between communication terminals located in respectively different countries and a method for operating the system, and more particularly, an international messaging system which can transmit a short message between communication terminals supporting different character systems of respectively different countries, and a method for operating the system. According to the present invention, it is possible to make and transmit a short message in a language of a first country from a communication terminal supporting the language of the first country to a communication terminal not supporting the language of the first country. Also, it is possible to transmit a short message in a language of a first country from a communication terminal not supporting the language of the first country to a communication terminal supporting the language of the first country.

Abstract: The present invention relates to an immunoassay and diagnostic reagent for malaria by using antigens of malarial Protozoa. More preferably, the present invention relates to an immunoassay and diagnostic reagent for malaria which detect malaria-specific antibodies in blood by using Merozoite Surface Protein of Plasmodium vivax. The immunoassay and diagnostic reagent detecting malaria-specific antibodies in blood according to the present invention have high specificity and sensitivity and are useful in diagnosing a type of malaria where latent period is long and number of Protozoa in blood if few. Also, the present invention relates to a preparation method of the surface protein of malarial Protozoa using yeast or E. Coli. Preferably, the present invention provides an expression vector comprising genes of Merozoite Surface Protein of Plasmodium Vivax and histidine residues, as well as transformants transformed with the expression vector.

Abstract: The present invention relates to diagnostic reagents for antibody against hepatitis B surface antigen and for antibody against hepatitis B virus using a sandwich immunoassay as a quantitative or qualitative analysis method for antibody against hepatitis B surface antigen and for antibody against hepatitis B virus, characterized in that each diagnostic reagent comprises a pair of hepatitis B surface antigens which are different each other and composed of primary antigen immobilized on a solid support and secondary antigen conjugated to a marker. Also, the present invention relates to preparation methods thereof. Further, the present invention relates to diagnostic methods for antibody against hepatitis B surface antigen and for antibody against hepatitis B virus.

Abstract: A method for preparing a highly dense product from a powdered mixture of reactants, whereby simultaneous application of a high current and pressure enables synthesis and densification of a variety of high temperature materials. The combination of field-activated combustion synthesis and the application of mechanical pressure was employed to produce dense MoSi.sub.2.
