Abstract:
PURPOSE: Alphavirus-based expression vectors expressing tumor suppressor proteins, a method for preparing the same and the use thereof are provided, thereby simultaneously expressing various tumor suppressor proteins, and consequently suppressing tumor effectively. CONSTITUTION: The alphavirus-based expression vector expressing tumor suppressor proteins comprises a first tumor suppressing gene or angiogenesis suppressing gene which is operably linked to a first subgenomic promoter; a second tumor suppressing gene or angiogenesis suppressing gene which is operably linked to a second subgenomic promoter; and a third tumor suppressing gene or angiogenesis suppressing gene which is operably linked to a third subgenomic promoter, wherein the first, second and third tumor suppressing genes or angiogenesis suppressing genes are the same or different; the tumor suppressing gene is p53 gene or PTEN gene; the antigiogenesis suppressing gene is angiostatin gene; and the alphavirus-based expression vector expresses tumor suppressor proteins Semliki forest virus(SFV) and Sindbis virus.

Abstract:
PURPOSE: A medical adhesive composition is provided to use poly-gamma-glutamic acid, thereby having edible, water-soluble, anionic, biodegradable properties. CONSTITUTION: A medical adhesive composition comprises poly-gamma-glutamic acid or salt thereof, and sugar or sugar alcohol. The poly-gamma-glutamic acid salt is selected from sodium polyglutamate, polyglutamic acid potassium salt, polyglutamic acid calcium salt, and polyglutamic acid ammonium sat, and polyglutamic acid zinc salt. The molecular weight of the poly-gamma-glutamic acid and salt thereof is 1-15,000 kDa. The salt is selected fructose, glucose, mannose, sucrose, maltose, trehalose, oligosaccharide, starch and maltodextrin. The sugar alcohol is selected from xylitol, lactitol, isomalt, sorbitol, maltitol, and glycerol.
Abstract:
PURPOSE: An immune adjuvant composition containing polygamma glutamic acid-chitosan nanoparticle and a composition containing the same for vaccine are provided to enhance antibody production rate without toxicity and side effects. CONSTITUTION: An immune adjuvant composition contains polygamma glutamic acid-chitosan nanoparticles. The polygamma glutamic acid-chitosan nanoparticles are conjugated by ion bond of polygamma glutamic acid and chitosan. The surface charge of the polygamma glutamic acid-chitosan nanoparticle is negative charge. A composition of immune adjuvant is administered together with antigen to animal except for human. A vaccine composition contains the polygamma glutamic acid-chitosan nanoparticles and antigen. The vaccine is used for treating or preventing cancer.
Abstract:
PURPOSE: A novel microbe, Leuconostoc mesenteroides subsp. Mesenteroides BLS35, is provided to ensure excellent strain growth ability. CONSTITUTION: An antiviral composition contains Leuconostoc mesenteroides subsp. Mesenteroides BLS35(KCTC18159P) or culture liquid thereof. The strain is isolated from Kimchi. A pharmaceutical composition for preventing influenza infection contains the strain or culture thereof. A supplementary nutraceutical agent for preventing influenza infection contains the strain or culture thereof as an active ingredient. A food additive contains the strain or culture thereof.
Abstract:
A novel Lactobacillus plantarum BLS41 which is derived from Kimchi is provided to have antifungal and antibacterial activities and use as an ingredient of eco-friendly microorganism agent. A Lactobacillus plantarum BLS41(KCTC 11056BP) which is derived from Kimchi has antifungal or anti-pathogenic acitivies. The antifungal agent comprises Lactobacillus plantarum BLS41(KCTC 11056BP) or its culture product. The antifungal agent is produced in a form of liquid suspension, stabilized liquid suspension, emulsified concentrate, capsule, aqueous flowables, dry flowables, or granule. The fungus is Erwinia sp., Pseudomonas sp., or Fusarium sp.
