Abstract:
PURPOSE: A double-transgenic dementia mouse expressing a mutant PS2 gene and an APPsw gene is provided to show perfectly dementia symptoms and to be useful in developing a dementia treatment and improving an early diagnostic test of the disease. CONSTITUTION: The double-transgenic dementia mouse is produced by mating a single-transgenic mouse(A) with a single-transgenic mouse(B). The transgenic mouse(A) expressing a mutant PS2 gene is produced by following steps of: preparing a recombinant fusion gene by connecting an mutant PS2 gene to a promoter of a Neuron-Specific Enolase gene; microinjecting the recombinant fusion gene into a fertilized egg of a mouse; and breeding the transgenic mice(A) by nidating the fertilized egg into a surrogate mother mouse. The transgenic mouse(B) expressing an APPsw gene is produced in the same manner.
Abstract:
PURPOSE: A label for sensing temperature and time for cold distribution management is provided to promptly and accurately sense that products are exposed at a higher temperature than a regular temperature. CONSTITUTION: A heat sensitive hydrogel(1) is manufactured by using an acryl monomer contracting and expanding in volume by discharging and absorbing an aqueous solution according to the temperature to measure the temperature of exposure of a product to be kept at a cold temperature. A transfer paper(2) contains dye for measuring elapsed time according to the temperature of exposure. A capillary tube path(3) connects the heat sensitive hydrogel with the transfer paper, so that the hydrogel moves to the transfer paper through the capillary tube path if the hydrogel is leaked at a lower critical solution temperature.
Abstract:
PURPOSE: A pharmaceutical composition containing an Allium victorialis var. platyphyllum extract having a therapeutic and preventing activity against arteriosclerosis as an effective component is provided which can be effectively used as a pharmaceutical component and an effective component of functional food for prevention and treatment of arteriosclerosis and hypercholesterolemia. CONSTITUTION: A dried Allium victorialis var. platyphyllum is ground to 20 to 100 mesh, mixed 2 to 5 times with ethanol and extracted at 15 to 50deg.C for 24 to 96 hr. The extract remarkably reduces the amount of cholesterol and lipid peroxide in blood and has an inhibition activity on cholesteryl ester transfer protein enzyme for transferring HDL cholesterol to arteriosclerosis-inducing low density lipoprotein cholesterol.
Abstract:
PURPOSE: A natural antioxidant containing an Origanum majorana extract as an effective component and process for purifying the same are provided, which can be used as a food additive for the prevention or inhibition of oxidative damage of protein, nucleic acid and enzyme in vivo. CONSTITUTION: The antioxidant having superoxide radical scavenging activity contains an Origanum majorana extract as an effective component, wherein the extract is obtained by extracting Origanum majorana with methanol or methanol and/or chloroform and ethyl acetate successively and purifying with an absorption chromatography.

Abstract:
PURPOSE: Extract from STAPF showing excellent effect in the HBV medicine field is provided, which has lower toxicity than any other existing compounds, so the extract from STAPF can be used as a safe and effective medicine for hepatitis B. CONSTITUTION: Extract from STAPF is gained from stems of STAPF. The extracting process comprises of: drying the stems thoroughly at place being well ventilated, or sunning the stems after drying till 60% dried state at place being well ventilated; adding 1L of water per 100g of dried STAPF; heating and gyrating for 2-3hrs at 100°C; extracting only 1 time. Dried powder type of the extract after freeze-drying, and water-soluble part of the extract by centrifuging after dissolving the dried powder are also used as an effective ingredient in the medicine for hepatitis B.
