Abstract:
According to the present invention, fractions derived from pine leaves with an inhibitory activity on an angiotensin converting enzyme are selected, and dehydroabietic acid and communic acid are identified by identifying structures among the selected materials with optimum activity. Provided are a health promotion food composition comprising dehydroabietic acid or communic acid as active ingredients for preventing or curing hypertension, a pharmaceutical composition for preventing or curing hypertension, an angiotensin converting enzyme inhibitor, and a pharmaceutical composition for preventing or curing vascular diseases. According to the present invention, dehydroabietic acid or communic acid derived from pine leaves has angiotensin converting enzyme inhibitory activity, and can be provided as a useful composition for consumer`s health. Since a method for extracting and segmenting is provided specifically in the present invention, the materials with excellent activity which is abundantly contained in pine leaves can be used as an economical raw material with a high function.
Abstract:
PURPOSE: A potato plant with resistance to PVY(potato virus Y) which is transformed by Ry gene is provided to enhance virus resistance and to overcome potato shortage due to viral diseases. CONSTITUTION: A potato plant with PVY resistance is prepared by transforming with a recombinant expression vector containing Golden Valley potato-derived Ry gene. The Ry gene has a base sequence of sequence number 1. The plant is Winter valley species. The PVY resistance of the potato is enhanced by transforming a potato plant with the recombinant expression vector.
Abstract:
The present invention relates to a polyacrylic acid macromolecule having antithrombotic activity and to uses thereof. According to the present invention, when the polyacrylic acid macromolecules is used as an antithrombotic, blood clots in blood are degraded and removed. Consequently, factors for regenerating blood clots can be basically removed. Moreover, when blood is treated with the polyacrylic acid to be stored, substances, which coagulate blood, are removed at the starting point. Therefore, the polyacrylic acid macromolecule having antithrombotic activity can prevent blood coagulation and be used for developing artificial blood powder.
Abstract:
The present invention relates to a protocatechuic acid derivative having an antithrombotic activity and to a use thereof. An antithrombotic pharmaceutical composition according to the present invention can be applied to common beverages, dietary supplements, or medicine, thus is expected to be able to prevent and treat diseases involving thrombopoiesis such as arteriosclerosis, cerebral hemorrhage, stroke, or cerebral infarction.
