Abstract: A method for manufacturing a criss-cross type X-ray grid may include: forming a plurality of criss-cross type grooves at predetermined intervals in a longitudinal direction and a lateral direction in a substrate made of an X-ray transparent material, through a semiconductor sawing machine, such that the grooves form a checker board shape as a whole; putting the substrate having the criss-cross type grooves formed therein into a storage tank filled with a molten X-ray absorbent material; filing the criss-cross type grooves, formed in the substrate, with the X-ray absorbent material by vacuuming the inside of the storage tank; and taking the substrate filled with the X-ray absorbent material out of the storage tank, and curing the substrate at room temperature.

Abstract: Disclosed is a composition for treating or preventing amyloid-related diseases including 4-O-methylhonokiol as an active ingredient. More specifically, a pharmaceutical composition including 4-O-methylhonokiol, which is effective for treating or preventing amyloid-related diseases such as Alzheimer's disease, cognitive disorder, defective memory, amyloidosis, etc. is disclosed. The inventors of the present disclosure have found out for the first time that 4-O-methylhonokiol inhibits the production of ?-amyloid. It has been confirmed to be useful in treating or preventing amyloid-related diseases. Through animal tests including water maze test and passive avoidance test on mice, 4-O-methylhonokiol has been confirmed to be effective for amyloid-related diseases such as Alzheimer's disease, defective memory, cognitive disorder, and the like.

Abstract: Disclosed is an anti-aging composition for external use on skin, which includes low-molecular weight hyaluronic acids, high-molecular weight hyaluronic acids and polysaccharides extracted from root bark of Ulmus davidiana, as active ingredients. The composition including the low-molecular weight hyaluronic acids, high-molecular weight hyaluronic acids and polysaccharides extracted from root bark of Ulmus davidiana, in a predetermined ratio, shows significantly improved skin-moisturizing, skin elasticity-enhancing and inflammation-alleviating effects, as compared to a composition using one of the above ingredients alone. Therefore, the composition may be widely used as a pharmaceutical or cosmetic anti-aging composition.
