Abstract:
PURPOSE: An evaluation method is provided to objectively measure the relief effect of sensory skin irritation by quantifying the relief effect of sensory skin irritation about various anti-irritants through the change of concrete threshold. CONSTITUTION: A sensory skin irritation relief effect evaluation method comprises a step of measuring the change of a threshold before and after spreading an anti-irritant to a stimulus applied to the skin sensory nerve. The evaluation method quantitatively measures the change of the threshold by using a device. The evaluation method measures the change of the threshold value about a stimulus applied to at least one skin sensory nerve which is selected in a group which includes Aα, Aβ, Aδ, and C-fiber type. The evaluation method measures the change of the threshold value about a stimulus which is applied to the skin sensory nerve of Aδ or C-fiber type.
Abstract:
A method for searching materials inhibiting the interaction between PRP19 and CLIC protein is provided to inhibit the formation of adipose, prevent and treat the disease mediated by the interaction between PRP19 and CLIC protein. A method for searching a material which inhibits the interaction between PRP19 and CLIC protein comprises: a step of reacting PRP19 protein or it U-box domain and CLIC protein; a step of measuring the amount of probe; and a step of selecting candidate material which decreases the amount of probe. A cosmetic composition contains 0.0001-20 weight% Elaeocarpus sylvestrisvar.ellipticus (Thunb.)Hara extract as an active ingredient. A pharmaceutical composition for preventing and treating obesity contains 0.0001-100 weight% of Elaeocarpus sylvestrisvar.ellipticus (Thunb.)Hara extract.
Abstract:
A transgenic mouse is provided to show obese-inhibiting characteristic by over-express an isocitrate dehydrogenase 3 alpha(IDH3A), there by being used as a model animal for treating and studying obesity. An expression vector pcDNA-IDH3A comprises: a CMV promoter; an IDH3A gene; and a polyadenylated sequence. A method for preparing a transgenic Mus musculus comprises the steps of: (a) preparing the expression vector pcDNA-IDH3A; and (b) micro-injecting the expression vector into a pronucleus of a Mus musculus fertilized egg. Further, the IDH3A gene is cDNA synthesized from mRNA derived form human heart.
Abstract:
A transformed cell line is provided to identify a chemical material controlling expression of an IDH3A gene at a transcription step and also find out an anti-obese material such as genistein. An expression vector pIDH3A comprises: a kanamycin resistant gene(Kana+) and a neomycin resistant gene(Neo+); a luciferase gene(LUC+); and an IDH3A promoter of SEQ ID : NO. 1 and has a structure depicted in Fig. 2. A cell line PRDC IDH3A transformed by the expression vector is deposited as a deposition no. KCTC 10981BP. A method for searching an obesity controlling material comprises the steps of: (a) treating the cell line with an obesity controlling candidate material; and (b) detecting the fluorescence emitting reaction, wherein the obesity controlling candidate material is treated with at least two concentrations.
