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 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:
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.
