Abstract:
An immunostimulant containing the lystic extract of Streptomyces albus is provided to reinforce the functions of various immune cells having the major role in the disease defense, thereby increasing the specific and nonspecific resistance to the disease infection of animals. The immunostimulant contains the lystic extract of Streptomyces albus which is prepared by cultivating Streptomyces albus in yeast malt extract agar broth at 26 deg. C for 72 hours, centrifuging the cultured fluid at 3000Xg for 30 minutes and collecting it, rinsing the collected pellet with phosphate buffered saline(PBS) of pH 7.2 and suspending the rinsed pellet in PBS, adding 5% of TNT solution containing 50mM of Tris-HCl, 0.15M of NaCl and 4% Triton x-114 as solubilizing agent into the Streptomyces albus suspension, stirring the mixture at room temperature for 2-3 days to solubilize the Streptomyces albus, and regulating pH of the solution to 6.5-7.2, and drying the solution in the thermostatic chamber.
Abstract:
A method for diagnosing the infection of vancomycin-resistant Enterococcus is provided to allow whether vancomycin-resistant Enterococcus is infected or not rapidly and effectively. A method for diagnosing the infection of vancomycin-resistant Enterococcus uses the antigen-antibody reaction with the specific antigen of vancomycin-resistant Enterococcus. Preferably the vancomycin-resistant Enterococcus is any one selected from Vancomycin-resistant Enterococcus phythium (VREFM), Vancomycin-resistant Enterococcus faecalis (VREFS), Vancomycin-resistant Enterococcus gallinarum (VREG), and Vancomycin-resistant Enterococcus casseliflavus.
Abstract:
An extract of Bupleuri Radix is provided to increase various activities of main immunocytes of an animal such as granulocyte and macrophage and induce strong defence capability on attach inoculation of pathogenic bacteria. A composition comprising the same extract is provided to be used as an animal medicine such as an animal immuno-enhancing agent and a vaccine adjuvant and a feed additive for treating and preventing animal diseases efficiently. A method for purifying an extract of Bupleuri Radix comprises the steps of: (a) heat-treating the Bupleuri Radix with hot water at a temperature of 80-120 deg.C for 2-3 hours to obtain a crude extract; (b) concentrating the crude extract; and (c) filtering the concentrate to obtain a polysaccharide fraction by filtering paper and microorganism filtering. An extract of Bupleuri Radix purified by the method is a Bupleuri Radix polysaccharide, of which sugar is a glycoprotein including a protein. A composition for increasing immunity comprises the extract of Bupleuri Radix as an active ingredient and a pharmaceutically acceptable carrier or an excipient. An animal immunity enhancing agent, a vaccine adjuvant, or a feed additive for an animal comprises the composition for increasing immunity as an active ingredient.
Abstract:
An extract of Rehmannia glutinosa is provided to increase various activities of neutrophil or macrophages and induce strong protectivity on attack inoculation of pathogenic bacteria, thereby being used as an immune enhancing agent, a vaccine adjuvant, an adjuvant therapeutic agent and a feed additive for an animal. An extract of Rehmannia glutinosa enhances immunity of an animal by increasing the activity of immunocyte such as neutrophil or macrophages. A method for preparing the extract of Rehmannia glutinosa comprises the steps of: (a) boiling dried Rehmannia glutinosa with distilled water to obtain the extract of Rehmannia glutinosa; (b) filtering the extract; and (c) hydrolyzing a filtrate.
Abstract:
An extract of Saposhnikovia root is provided to improve immune response by increasing activities of neutrophil, macrophage and lymphocyte, production of cytokines and non-specific protection against pathogenic bacteria infection in animals, so that it is useful as immunomodulator and immunoadjuvant. An extract of Saposhnikovia root for improving immune response in animals is prepared by heating Saposhnikovia root in water, and administered into an animal, especially domestic animals including cow, pig and chicken in the amount of 10-20 mg/kg per day through oral administration, intravenous injection, intramuscular injection or subcutaneous injection.
Abstract translation:提供Saposhnikovia根的提取物,通过增加嗜中性粒细胞,巨噬细胞和淋巴细胞的活性,产生细胞因子和非特异性保护免受动物中的致病细菌感染来改善免疫应答,从而可用作免疫调节剂和免疫佐剂。 通过在水中加热山茱萸碱来制备Saposhnikovia根的提取物,并通过口服给药至每天10-20mg / kg的动物,特别是包括牛,猪和鸡的家畜,其量为10-20mg / kg ,静脉注射,肌内注射或皮下注射。
Abstract:

Abstract:
PURPOSE: A fusion cell line producing a monoclonal antibody specifically binding to E. coli O157 is provided to rapidly and exactly detect the infection of E. coli O157. CONSTITUTION: The microorganism NVRIO157(KCTC 0429BP) producing a monoclonal antibody specifically binding to E. coli O157 is produced by the steps of: immunizing a mouse with E. coli O157:H7 by injecting E. coli O157:H7 as an antigen into the mouse; separating immune cells that produce an antibody; and fusing the immune cells with myeloma cells to produce NVRIO157(KCTC 0429BP). The monoclonal antibody MNVRIO157 specifically binding to E. coli O157:H7 is produced from NVRIO157(KCTC 0429BP). The specificity of monoclonal antibody MNVRIO157 is analyzed by ELISA.
