Abstract:
PROBLEM TO BE SOLVED: To provide a promoter capable of easily undergoing a culture to a spheroid form.SOLUTION: A spheroid-forming promoter is characterized by being obtained by using a body fluid present in the trunk or a body fluid collected from the liver of cuttlefish or octopus among cephalopoda. The body fluid may be collected by squeezing or centrifuging, or by dripping through freeze-thaw technique.
Abstract:
PROBLEM TO BE SOLVED: To provide an extraction method capable of simply obtaining a collagen having high quality in good yield. SOLUTION: A crude collagen (2.5g) obtained from scales is weighed and 25 ml of 30% aqueous solution of the hydrogen peroxide is added to the weighed crude collagen and the mixture is allowed to stand for 16 hr. at a room temperature of 20°C to 25°C. Then, 200 ml of 0.02N acetic acid is added to the mixture of aqueous hydrogen peroxide with the crude collagen and the mixture is allowed to stand for 72 hr. in this state. Then, the mixture of the aqueous hydrogen peroxide with the crude collagen and the acetic acid is subjected to centrifugal separation for 10 min in 1.000 rpm number of revolutions to remove an insoluble ingredient. Further, the mixture is dialyzed to remove a low-molecular weight component such as hydrogen peroxide and acetic acid, and freeze-drying of the treated mixture is carried out to provide 1.53g collagen in 61.2% yield.

Abstract:
PROBLEM TO BE SOLVED: To provide an atrial remodeling inhibitor for prophylaxis and therapy of chronic atrial fibrillation, wherein Kv1.5 protein that is an ion channel is reduced to make an antiarrhythmic drug ineffective by the atrial remodeling. SOLUTION: The atrial remodeling inhibitor includes EPA (eicosapentaenoic acid) in a low dose for increasing the Kv1.5 protein in cardiac muscle, wherein the EPA is orally and chronically administered to a patient. The atrial remodeling inhibitor can prevent even a decrease in cardiac contractility, thrombus, embolism, or cerebral apoplexy etc., caused by the atrial fibrillation. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a collagen peptide which produces a large amount of an uncolored collagen peptide in a short time. SOLUTION: The method for producing a collagen peptide suppressed in coloration or uncolored, includes heating a collagen-containing raw material or collagen in the presence of hydrogen peroxide. A collagen-containing raw material or collagen is heated and treated with a proteinase before the hydrogen peroxide treatment to obtain a collagen peptide in a shorter time.

Abstract:
PROBLEM TO BE SOLVED: To provide a promoter capable of easily undergoing a culture to a spheroid form. SOLUTION: The spheroid-forming promoter is characterized by being obtained by using the body fluid of predetermined fish having mucosal body skin, wherein the body fluid is collected from the sites ranging from the skin to muscular tissue. It is preferable that the body fluid to be used is Allolepis hollandi, Lycodes tanakai Jordan and Thompson or flatfish one. Another version of the promoter is characterized by being obtained by using the body fluid present on the inner surface of the trunk of cuttlefish or octopus, or collected from the liver thereof; wherein the body fluid may be collected by squeezing or centrifuging the relevant fish, cuttlefish or octopus or by dripping through freeze-thaw technique.

Abstract:
PROBLEM TO BE SOLVED: To provide a new method for producing nata de coco with the intention for preventing microbial tainting and for space saving and production process shortening. SOLUTION: The method for producing nata de coco is provided with a seed culture step as stirring culture, and microbial tainting is prevented in the seed culture step, thus saving a working space. Cellulose lumps developed in a seed medium are removed by either one process among the following processes:(1) seed medium filtration; (2) a seed culture is made using a cellulase-containing seed medium; and (3) cellulase is added to the seed medium after completing the seed culture. By removing cellulose lumps in the seed medium, cellulose lumps are prevented from mixing into the culture medium, enabling nata de coco sheet surface to be smoothed. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a technology increasing workability and effectively extracting and isolating glycosaminoglycan and proteoglycan. SOLUTION: There is provided a volume reduction extraction method of glycosaminoglycan, which comprises adding an alkaline aqueous solution to tissues derived from a living body to obtain an extraction liquid containing glycosaminoglycan, adding an acidic aqueous solution to the extraction liquid to generate precipitation to reduce volume, and exposing the precipitation to an acidic aqueous solution containing inorganic salts and adjusted its pH to be almost the pH in generation of the precipitation so as to elute glycosaminoglycan in the aqueous solution.
