Abstract:
PURPOSE: Novel aklavinone derivatives prepared by transforming biosynthetic variants with a vector containing aklavinone C-11 hydroxylase gene separated from Streptomyces sp and fermenting transformer thereof and process for producing the same are provided which can be effectively used for an antibiotic. CONSTITUTION: 2,11-Dihydroxyaklavinone of formula 1 is used in the manufacture of various new anthracycline antibiotics through bioconversion. Thus, 2,11-dihydroxyaklavinonecycline as anthracycline antibiotics is prepared by using the compound as a precursor, has low toxicity against a cell and is safer than conventional antibiotics.

Abstract:
The present invention relates to a method for manufacturing hyaluronic acid having low dissolving speed in the body and a composition for adhesion prevention comprising hyaluronic acid manufactured thereby. More specifically provided are a method for manufacturing hyaluronic acid having low dissolving speed in the body including a step for cultivating streptococcus dysgalactiae ID9103 strains (KCTC11818BP) in a culture ground where carbon source and nitrogen source are included and a composition for adhesion prevention comprising hyaluronic acid manufactured thereby. Hyaluronic acid manufactured by the manufacturing method of the present invention has an excellent effect in adhesion prevention due to having low dissolving speed in the body as 4 million Da to 10 million Da of highly polymerized hyaluronic acid. A composition of the present invention for adhesion prevention comprising hyaluronic acid manufactured by the manufacturing method of the present method can ameliorate problems of the existing composition for adhesion prevention including cross-linker and compound and problems of the existing hyaluronic acid.
Abstract:
PURPOSE: A quadruple-coated lactic acid bacterium is provided to ensure acid and bile acid resistance, low bacterial death rate by high or low temperature, and to prevent loss of inherent physiologically active function of the bacteria by mixing lactic acid bacteria with a water soluble polymer, hyaluronic acid, a coating agent with a porous particle, and a protein, and quadruple-coating. CONSTITUTION: A method for preparing quadruple-coated lactic acid bacteria comprises: a step of mixing a water soluble polymer in lactic acid bacteria and primarily coating the lactic acid bacteria; a step of mixing the lactic acid bacteria with hyaluronic acid and secondarily coating the lactic acid bacteria; a step of mixing the lactic acid bacteria with a coating agent with a porous particle, and thirdly coating the lactic acid bacteria; and a step of mixing the lactic acid bacteria with a protein.
Abstract:
PURPOSE: A composition containing hyaluronic acid or salt thereof for treating hemorrhoid is provided to heal scar and to ensure skin protection, moisturizing, and tissue regeneration without side effects. CONSTITUTION: A pharmaceutical composition for treating hemorrhoid contains 0.01-5% of hyaluronic acid or salt thereof as an active ingredient. The sodium hyaluronic acid is prepared by dissolving in a sterilized saline solution. The pharmaceutical composition is manufactured in the form of suppository, ointment, gel, or cream. A method for manufacturing the suppository comprises: a step of melting Witepsol over 50°C and adding hyaluronic acid; a step of removing pores at 40°C; and a step of pouring the solution into a frame and cooling at room temperature.

Abstract:
PURPOSE: A microencapsulation method of spore-forming probiotics is provided to ensure excellent productivity and uniformity of a spore, and to enhance long-term preservation and regermination rates by the probiotics. CONSTITUTION: A method for preparing an autolysin-removed spore comprises a step of removing autolysin from entire spore by chemical shocks. A method for preparing thin film-coated microcapsulated spore-formed probiotics comprises: a step of performing primary thin film coating of the spore surface of the spore-forming probiotics using a water soluble polymer; and a step of secondarily microcapsulating. Polyvinyl pyrrolidone(PVP) is used as a thin film coating substrate for improving durability and stability of the spore.
