  • Patent number: 7534456
    Abstract: This invention includes a composition of Agastache rugosa and tilianin obtained by separation-purification for anti-inflammation and anti-atherosclerosis, and more particularly, an extract of Agastache rugosa and tilianin obtained therefrom by separation-purification which are effective in preventing and treating not only inflammatory diseases but also atherosclerosis related to inflammatory responses and disease in the circulatory system caused by atherosclerosis because they are excellent in inhibiting the activity of complement systems as a factor of inflammatory responses, the expression of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecular-1 (VCAM-1), and the production of nitric oxide (NO). They can also significantly reduce the development of atherosclerosis due to the inflammatory response.

  • Publication number: 20080113005
    Abstract: The present invention relates to a composition comprising extracts of Gramineae plant that improves cell viability under hypoxic conditions by inhibiting apoptosis. Thus, the extract of Triticum aestivum L., one of the Gramineae plant, of the present invention, in particular, prevents damage of brain, heart and kidney in animal models of ischemic diseases, and it also improves memory in an animal model of Alzheimer's disease. Therefore, a composition comprising extracts of Gramineae can be used as therapeutic agents or health care foods for preventing and treating ischemic diseases and degenerative brain diseases.

  • Patent number: 5114873
    Abstract: The method comprises the steps of: forming the transistor on a substrate and then depositing an interlayer insulating layer, and forming a design pattern of a first conductive layer by vertically etching it using a mask; horizontally overetching the pattern by using the etching process used for forming the pattern; depositing a first insulating film and then depositing the second conductive layer to the thickness needed to protect the first insulating film; vertically etching the second conductive layer, first insulating film and interlayer insulating layer by applying the mask used in vertically etching the first conductive layer; additionally depositing the second conductive layer; forming a design pattern of the second conductive layer by vertically etching it using a mask; horizontally overetching the pattern of the second conductive layer; depositing the second insulating film and then depositing a third conductive layer to have the thickness to protect the second insulating film; vertically etching the
