Abstract: Provided is a manual follicle-transplanting hair transplanter for increasing a graft survival rate. The manual follicle-transplanting hair transplanter includes a needle member having a lower end containing a follicle to be transplanted and having a head having a larger diameter than a portion below the head at an upper end thereof, a rod member inserted into the needle member and having a push portion having a larger diameter than a portion below the push portion at an upper end thereof, an inner body configured to contain the needle member and limit downward movement of the needle member, and an outer body configured to contain the inner body and limit upward movement of the needle member. The needle member is automatically withdrawn when a compressed spring disposed in the inner body expands and pushes up a lower surface of the head.

Abstract: Disclosed is a method of manufacturing an MMO anode using reel-to-reel continuous coating and heat treatment, including continuously coating a surface of a metal substrate with an MMO (Mixed Metal Oxide) coating solution using a continuous coater and passing the metal substrate through a heat pretreatment furnace and a heat treatment furnace to form an MMO coating layer on the surface of the metal substrate. When a long wire type MMO anode is manufactured, a uniform coating layer is formed thanks to the use of reel-to-reel continuous coating and heat treatment under uniform conditions, thus increasing durability and quality of the long wire type MMO anode. The exposure time of the metal substrate to the outside between the processes is minimized, and productivity is increased, thus decreasing the manufacturing cost to result in high product competitiveness.

Abstract: The present invention relates to dermal replacement prepared from mesenchymal cells of hair follicle. As compared with fibroblast, the mesenchymal cells separated from the hair follicle, especially from the hair follicle in human beard produce a lot of growth factor and matrix protein stimulating cell-regeneration, and produce a little enzyme decomposing matrix protein. Therefore, the dermal replacement prepared from the present invention has more excellent cell-regeneration effect than the conventional artificial skin.
