摘要:
An antimicrobial film formulation is prepared by extracting Portulaca oleracea using chloroform, petroleum ether or hot water, filtering and concentrating the extract, processing the concentrated extract into a liquid or powder state, and completely dissolving 0.25-0.5% (w/v) of the Portulaca oleracea extract, 1.5-2% (w/v) of chitosan and 0.5-2% (w/v) of glycerol in 100% (v/v) of vinegar (containing about 3-5% acetic acid).
摘要:
The present invention relates to a kit for screening for skin-activating substances, and to a method for screening for skin-activating substances using same. More particularly, the present invention relates to a kit for screening for skin-activating substances and to a method for screening for skin-activating substances using same, in which candidates for inducing the expression of the klotho gene are separated from skin cells by the screening kit comprising the klotho gene, also known as the anti-aging gene, and the separated candidates are refined, thus screening for skin-activating substances such as moisturizing, anti-aging, or whitening substances.

A method for displaying a stereoscopic image of a display apparatus, the display apparatus can divide a received frame image corresponding to the preset column areas to generate M sub-frame images. In this example, the display apparatus may include a plurality of lenticular lenses disposed over a display panel to divide the display panel into a plurality of column areas. Each of the lenticular lenses may include a lenticular plate converting a flat image displayed on each of the column area into K stereoscopic images having directions different from each other. The M sub-frame images may be displayed on the display panel in a time division method. M shutters disposed over the M lenticular lenses according to the sub-frame image displayed on the display panel may selectively be opened and closed. Herein, K and M are natural numbers.

Provided are a method for preventing damage to the nuclear membrane of skin cell including administering an effective amount of amentoflavone to a subject and a method for anti-aging including administering an effective amount of amentoflavone to a subject. By controlling the expression of defective lamin A induced by UV radiation or controlling the expression of phosphorylated H2A histone family, member X (H2AX) induced by UV radiation, the disclosed method prevents nuclear membrane damage and thus prevents skin cell damage. Accordingly, a composition containing amentoflavone as an active ingredient may be used as a cosmetic composition or a pharmaceutical composition.

摘要:
Disclosed is a method for screening a substance inhibiting inflammatory skin aging, comprising: treating an immune cell with an inflammatory stimulant; treating a skin cell with a candidate substance; treating the skin cell treated with the candidate substance, with the immune cell treated with the inflammatory stimulant; and measuring the concentration of matrix metalloproteinase-1 (MMP-1) in the skin cell treated with the immune cell.
