Abstract: The present invention discloses a topical scalp and transdermal preparation with excellent penetration to the skin and follicle, containing a [?-hydroxy-N-methyl-L-leucine4] cylosporin derivative which is a non-immunosuppressive component with hair growth stimulating ability. The topical scalp and transdermal preparation is prepared by incorporating the cyclosporin derivative into a liposome, microcapsule, micro-sphere, composite particle or emulsion, capable of being employed as a hair growth stimulating agent and applied for the prevention of hair loss.

Abstract: The present invention discloses a hair growth promoting agent comprising a cyclosporin derivative as an active ingredient, and more particularly, a hair growth promoting agent comprising a cyclosporin A derivative substituted in the 3-position as an active ingredient.

Abstract: In an encoding method for use in an encoder to encode an image signal including an object having object pixels, a background having background pixels and a contour signal representing the contour of the object, the contour signal is first encoded based on mask data having first and second binary values to designate an object pixel and a background pixels, respectively and then decoded to generate a decoded contour. In the mean time, a primary padded image signal obtained by applying a primary padding on the image signal is divided into multiplicity of equal-sized primary padded blocks and then each of the primary padded blocks is defined either as a contour block or as an object block based on the decoded contour to thereby select contour blocks and object blocks.
