Abstract: A system for measuring sulphite in food samples is provided using a biosensor, a method for determining sulphite in food samples using the biosensor, and the biosensor for measuring the sulphite values in food samples. The system uses an amperometric biosensor having a bi-enzymatic system, a working electrode, a counter electrode and a reference electrode. The bi-enzymatic system has the human sulphite oxidase and peroxidase enzymes, and the immobilisation of the enzymes in the working electrode is carried out via simple physical retention. The mixture of the enzymes is mixed with a chemical mediator by applying a sample to the amperometric biosensor; changing the electrical current upon coming into contact with the analyte to be detected; and amperometrically measuring said electrical current in solutions with continuous agitation, using a constant potential.

The biological product can be used for the decomposition of degradation-resistant pesticides and oil and has plant growth stimulating and fungicidal activity.

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.

Abstract: The present invention relates to a method for preparing a contact lens-shaped amniotic dressing and a contact lens-shaped amniotic dressing prepared therefrom for treating ocular surface diseases, which does not require the use of sutures or an adhesion material. The inventive contact lens-shaped amniotic dressing is capable of solving the problems associated with suturing an amniotic membrane, e.g., highly delicate surgical techniques of suturing, long surgery time, stitch abscess, granuloma formation, tissue necrosis, and discomfort of patients; and the problems associated with the use of a support, e.g., the elimination of the support by eye blinking, breaking of the support, and discomfort.

Abstract: The present invention is related to novel cosmetic composition comprising beta-fructosyl-L-ascorbic acid derivatives produced by fructose conversion reaction using by ascorbic acidskin whitening cosmetic composition as an cream, skin, lotion, pack and the like.
