Abstract:
PURPOSE: A powder of mother-of-pearl layer or a prism layer from a comb pen shell is provided to ensure a skin care effect and to be used as an ingredient of medicines, pharmaceutical products, and cosmetics. CONSTITUTION: A powder of a mother-of-pearl layer or a prism layer is prepared from a comb pen shell. The mother-of-pearl layer powder is prepared by naturally drying the comb pen shell for 3-5 days, or by naturally drying the same for 0.5-24 hours and then drying at a high temperature of 50-80 deg.C. for 1-5 hours, and pulverizing an isolated mother-of-pearl layer. The powder of a mother-of-pearl layer or a prism layer from the comb pen shell comprises: a step of removing impurities from the comb pen shell and washing the comb pen shell; a step of drying the washed comb pen shell; a step of isolating the mother-of-pearl layer or the prism layer; and a step of pulverizing the mother-of-pearl layer or the prism layer.

Abstract:
PURPOSE: A cultivation method of a penshell black pearl is provided to regulate the physiology of a penshell by a land based seawater method for controlling the injection of seawater from September-November to next April-June and to cultivate a high quality black pearl by using a nucleus surgical method, which injects a nucleus and shell slice into the gonad in which a foot and posterior reactor muscle are connected. CONSTITUTION: A cultivation method of a pen shell black pearl comprises; (1 step) a step of controlling the physiology of a penshell by a land based seawater method, which equips culture system and controls the injection of seawater with changing 0.5-2 times per day from September-November to next April-June; (2 step) a step of preparing mantle segment by cutting mantle buffy coat part into 5-7mmx5-7mm by using penshell for mantle segment supply; (3 step) a step of inserting a nucleus with a diameter of 7-13mm and the mantle segment of the second step into the gonad in which a foot and posterior reactor muscle are connected of the penshell of the first step; and (4 step) a step which the penshell inserted with the nucleus is cultivated for 5-8 month by hanging method.
