Abstract:
The present invention relates to a method for determining dormancy awakening of Osmia cornifrons and, more specifically, to a method for quantitatively measuring the dormancy awakening of Osmia cornifrons by measuring oxygen consumption of Osmia cornifrons using a biological respirometer. The present invention provides the method for quantitatively measuring the dormancy awakening of Osmia cornifrons, thereby adequately supplying Osmia cornifrons in a time of need.
Abstract:
The present invention relates to a method for preparing an insect-derived composition for a preparation substituting for heparin and a use thereof. More specifically, the present invention relates to a method for preparing insect glycosaminoglycan capable of being used as a substituent for heparin or a composition for a preparation substituting for heparin, and a use of suppressing inflammation or enhancing immunity of the insect glycosaminoglycan or the composition for a preparation substituting for heparin, which is prepared by the said method. The preparation method of the present invention can provide useful glycosaminoglycan from insects. Furthermore and according to the preparation method of the present invention, heparin high and low molecular weight medicines, which are a kind of glycosaminoglycan, can be manufactured from various species of insects, and heparin and the likes can be produced at low costs whereby the present invention can contribute to the improvement of the national health and preserve the incomes of the insect breeding farmers.
Abstract:
PURPOSE: A method for preparing an insect-derived heparin substituent composition and a use thereof are provided to manufacture high molecular and low molecular drugs from various kinds of insects. CONSTITUTION: A method for preparing an insect-derived heparin substituent composition comprises: a step of immersing insects in an organic solvent, removing fats, filtering, and drying a residue; a step of pulverizing the dried residue; a step of treating the residue with protease and hydrolyzing proteins; a step of removing hydrolyzed proteins; a step of collecting saccharides and obtaining insect glycosaminoglycan; and a step of hydrolyzing the insect glycosaminoglycan and removing sulfate groups.
