摘要:
Disclosed is an evaluating method for the properties of a corneocyte in a horny layer sample originating in the skin. In the above method, detected and evaluated are selective staining of a cornified envelope in a corneocyte, selective staining of a nuclear component and the antigenicity.
摘要:
A method for accelerating cutaneous barrier recovery and a method for preventing epidermal hyperplasia by inhibiting production of Nitric Oxide by an epidermal cell are provided.
摘要:
A skin barrier function recovery and promotion composition containing, as an active ingredient, a fragrance which is effective when evaluated by applying a predetermined stress to a model experimental animal, in a system to which the tested fragrance is not applied, to thereby reduce the skin barrier function of the animal and using this data of the degree of recovery of the skin barrier function as an indicator and evaluating the capability by the difference between this data and data of the degree of recovery of the skin barrier function in a system to which the tested fragrance is applied.
摘要:
A first subject of the present invention is an insoluble powder characterized in that a zeta-potential is a negative value.It is preferable that barium sulfate is a main ingredient in the insoluble powder.It is preferable that an average primary particle diameter is 3 to 100 μm, and an aspect ratio is 3 to 250 in the insoluble powder.It is preferable that the insoluble powder is a metal-doped barium sulfate powder obtained by reacting a barium ion and a sulfate ion in the presence of a metal ion.It is preferable that the metal ion is one or more selected from the group consisting of a lithium ion, a sodium ion and a zinc ion in the insoluble powder.A second subject of the present invention is a skin barrier function recovering powder, or a skin roughening preventing and improving powder, which comprises the aforementioned powder.A third subject of the present invention is a skin external composition characterized in that a content of the aforementioned powder is 1 to 40% by weight.
摘要:
A method is provided for producing a visual image of ions in a thin frozen tissue sample by placing the tissue sample in contact with a thin membrane having a water soluble gel or hydrophobic plastic thin film which has incorporated in or placed on its surface a fluorescent or color ion indicator which fluoresces or changes color under light of a particular wavelength. The thin frozen tissue sample is then subjected to light having a wavelength to cause the ion indicator to fluoresce or change color.
摘要:
A method for increasing oxytocin release through direct action on the epidermal keratinocytes is provided. The method for increasing oxytocin release in the epidermis includes increasing the calcium ion concentration in the epidermal cells. In the method of the present invention, the increase of the calcium ion concentration in the epidermal cells may be achieved by physically stimulating the skin. The physical stimulation may be achieved by applying a heat stimulus and/or a massage. The increase of the calcium ion concentration in the epidermal cells may be achieved by stimulating the epidermal cells by at least one agent selected from the group consisting of ATP, UTP, 4 alpha-phorbol 12,13-didecanoate, and pharmaceutically acceptable salts thereof.
摘要:
A novel skin barrier function recovery acceleration method and accelerator are provided. The present invention provides a skin barrier function recovery accelerator that comprises a TRPA1 agonist capable of activating TRPA1 in epidermal cells.
摘要:
A method for accelerating cutaneous barrier recovery by inducing efflux of potassium ion from an epidermal cell as well as a method for preventing epidermal hyperplasia induced by inducing efflux of potassium ion from an epidermal cell are provided.
摘要:
The present invention provides a method and composition which ameliorate inflammation, and suppress its onset, by allowing ATP receptor antagonists to act on ATP receptors of cells to block them and thereby inhibit the release of inflammatory cytokines, particularly interleukin-6 (IL-6) and/or interleukin-8 (IL-8), by the cells.
