摘要:
Disclosed is a non-natural ceramide compound effective for a sphingosine kinase activator, and thus useful for a skin disease treating agent. The sphingosine kinase activator enhances production of sphingosine-1-phosphate to show various physiological activities provided by sphingosine-1-phosphate. The physiological activities include the effects of: controlling multiplication and differentiation of keratinocytes, multiplication of fibroblasts and collagen synthesis, resulting in treatment of wounds, recovery of damaged skin functions in atopic dermatitis and psoriasis; inhibiting wrinkles and skin irritation caused by ultraviolet rays, followed by improvement of wrinkles and inhibition of skin aging; and reducing skin atrophy, which is a typical side effect of local application steroids. Therefore, the sphingosine kinase activator is useful for a skin disease treating agent for treating skin wounds, wrinkles, atopic dermatitis, eczema, psoriasis, or skin atrophy caused by side effects of local application steroids.

There is provided a composition for preventing and treating obesity including high water-soluble β-cyclodextrin derivatives as an effective component. Specifically, the composition including the high water-soluble β-cyclodextrin derivatives, especially, 2-hydroxypropyl-β-cyclodextrin (HP-β-CD, HPBCD) has effects on suppressing an increase in body weight induced by a high fat diet, suppressing appetite through decreasing an amount of dietary intake, decreasing body fat, decreasing liver weight, and significantly decreasing a sharp increase of blood sugar induced by intaking glucose and maltose on an empty stomach so that it can be useful for preventing and treating obesity, preventing and treating various diseases induced by obesity, and suppressing a sharp increase of blood sugar after dinner.
摘要:
A method for fabricating a membrane is disclosed, to provide both hydrophilicity and hydrophobicity to predetermined positions of a surface of a single membrane. The method for fabricating a membrane includes: preparing a template with nano-scale holes formed on its outer surface; coating a polymer material on a predetermined pattern region of the outer surface of the template; attaching a hydrophilic film on the outer surface of the template; and removing the template from the hydrophilic film.
摘要:
A method for preparing an ester bleach activator compound is disclosed. The method includes (A) preparing fatty acid monoester; (B) making chloroformate by reacting the fatty acid monoester with at least one selected from the group consisting of phosgene, diphosgene and triphosgene in the presence of base; and (C) reacting the chloroformate with hydroxybenzene, its derivatives, or its salts in solvent. According to the method, the ester bleach activator compound can be made in a simple and economic way.

摘要:
The present invention relates to a laser-rotating arc hybrid welding system and a welding method using the system. The laser-rotating arc hybrid welding system of the present invention includes an arc discharge unit (2) for generating arc discharge along an area to be welded. A laser generation unit (4) radiates laser light onto the area to be welded. A rotating device (24) rotates the arc discharge unit (2). In the welding method using the laser-rotating arc hybrid welding system, a plurality of parent metals is aligned with a welding location. A laser-rotating arc hybrid welding system is located with respect to an area to be welded, arc discharge is generated while an arc discharge unit is rotated at a predetermined turning radius, and laser light is subsequently radiated using a laser generation unit.
