Vet. Sci. 2000 1 1 49-52 JOURNAL OF Veterinary Science Relation between lymphocyte subpopulations of peripheral blood and immune responses of modified live hog cholera virus vaccine in pigs treated with an ionized alkali mineral complex Bong-kyun Park Yong Ho Park Kyung-suk Seo1 Department of Microbiology College of Veterinary Medicine Seoul National University Suwon 441-744 Korea 1NEL Biotech Co. Ltd. Ansung 456-800 Korea Thirty-nine healthy pigs 28-32 days old were purchased from a commercial swine farm and housed at swine pens of the College. The animals were vaccinated intramuscularly 1 ml with an attenuated live hog cholera virus HCV LOM strain and then boostered at 5 weeks after the first vaccination. The animals were divided into 4 experimental groups w w PowerFeelTM-supple-mented diet T-1 n 10 3 w w SuperFeed -supplemented diet T-2 n 10 diluted PowerFeelTM solution 1 500 v v as drinking water T-3 n 9 control n 10 . PowerFeelTM is an original form of ionized alkali mineral complex IAMC and SuperFeedTMis a commercial product of IAMC. The subpopulation of lymphocyte in blood was assayed by a flow cytometry and HCV-specific antibody was determined by an indirect immunofluorescence assay. In IMAC-treated groups the proportions of subpopulation expressing MHC-class II Cd2 CD4 CD8 and surface IgM B lymphocytes were significantly decreased at 5-weeks after the first vaccination. Significant decreases were also observed in the proportions of MHC-class II CD2 and CD8 lymphocyte at 3-weeks after the booster injection. The humoral immune responses in T-1 and T-2 groups were greater than those in T-3 or control group. These results suggest that IAMC-supplemented diets may have an HCV-specific immunostimulatory effect in pigs. Key words Ionized alkali mineral complex lymphocyte subpopulations attenuated hog cholera virus vaccine Introduction Since hog cholera in Korea has been first recognized by laboratory tests in 1947 it has been one of the major Corresponding
