Abstract:
The oral vaccine of the present invention containing the HPV like particles is produced in edible transgenic plants and then administered through the consumption of the edible portion of those plants or after the purification of the particles. A DNA sequence encoding one of the HPV capsid proteins is isolated, inserted into the plasmid which comprises a plant-specific promoter and a gene for a selection marker, and then transferred to plant cells to give transgenic plants. Since the gene is expressed in a portion of the plants, the oral vaccine of the present invention can be produced in an inexpensive manner and administered in a simple method.
Abstract:
The present invention relates to a skin-protecting composition for the damaged skin, comprising glycyrrhizin, quercetin, rosmarinic acid, madecassic acid, chamazulene, bicalein and emodin. The composition of the present invention has all of excellent antioxidant, anti-inflammatory, wound-healing and moisturizing effects, thereby being widely used in medicine, cosmetic material or the like for the purpose of protecting the easily infectable, damaged and dried skin.
Abstract:
The present invention relates to a composition for improving skin condition comprising α-bisabolol as an active ingredient. α-Bisabolol used as an active ingredient has greater skin whitening effect inhibiting melanin synthesis by inhibiting intracellular tyrosinase activities compared to arbutin used as an existing skin whitening agent. In addition, α-bisabolol exhibits the inhibition effect on collagenase activity and promotion effect on collagen biosynthesis at a molecular level, contributing to excellent efficacy in improvement of skin wrinkles. Meanwhile, α-bisabolol indicates the improvement effects on UV-induced skin damage and the skin growth promotion or hair loss prevention. Therefore, α-bisabolol has the excellent improvement effects on skin condition. Furthermore, α-bisabolol has the excellent anti-obesity and anti-oxidation effects. The composition of this invention can be applied to cosmetic, pharmaceutical and food composition having no cytotoxicities and side effects with safety.
Abstract:
The present invention relates to a method for economically preparing ginseng extract having an increased content of physiologically active substances, comprising the steps of steaming ginseng at 95 to 100° C. for 1 to 24 hours, collecting the generated vapor by cooling, and repeating the process twice, to a composition for promoting collagen synthesis, comprising the extract, and to a cosmetic product for improving skin wrinkles, comprising the composition.

Abstract:
The present invention relates to a composition for improving skin conditions comprising matrine and oxymatrine as an active ingredient. Matrine and oxymatrine have lower cytotoxicity than retinol used as anti-wrinkle agents and exhibit the inhibition effect on collagenase activity and promotion effect on collagen biosynthesis at a molecular level, contributing to excellent efficacy in improvement of skin wrinkles. In addition, both matrine and oxymatrine exhibit the inhibition effect on melanin production by inhibiting intracellular tyrosinase activity, the improving effects of UV-induced skin damage and the skin growth promotion or hair loss prevention. Therefore, matrine and oxymatrine have the excellent improvement effects on skin conditions. Furthermore, matrine and oxymatrine have the excellent anti-obesity and anti-oxidation effects. The composition of this invention can be applied to cosmetic, pharmaceutical and food composition having no cytotoxicities and side effects.
Abstract:
Disclosed herein is a natural composite preservative comprising extracts from Camellia sinensis, Matricaria recutita, Citrus grandis, Magnolia biondii, propolis, Thujopsis dolabrata and Salix alba, in combination. The natural composite preservative has potent antibacterial activity against a wide spectrum of microorganisms in addition to being safe for the body, producing neither toxicity nor irritation, and thus can be applied to cosmetics, pharmaceuticals, and foods.
Abstract:
The present invention relates to a composition for promoting stem cell proliferation which contains a vegetable peptone. More specifically, this invention relates to: a serum-free composition for culturing stem cells which contains a vegetable peptone; a composition for improving skin condition containing the vegetable peptone as an active ingredient; and a composition for improving skin condition containing a culture medium as an active ingredient in which cultured stem cells are removed after being cultured in a serum-free composition medium for stem cell culture containing the vegetable peptone. Since the disclosed serum-free composition for culturing stem cells does not need the use of expensive animal serum, the manufacturing cost can be remarkably lowered. Also the use of anima serum in the medium can basically prevent contamination material caused by the use of animal serum. In addition, the disclosed composition containing the vegetable peptone and the medium in which the stem cells are cultured in the serum-free medium both serve to promote and activated the proliferation of stem cells, and improve various skin conditions.
Abstract:
The present invention relates to a skin-whitening composition comprising artemisinine. Artemsinine according to the present invention suppresses melanin synthesis and tyrosinase activity to inhibit pigmentation, and has excellent whitening effect and safety without side effects, thereby being used for improving melasma or freckles, and whitening skin.
