Abstract

This study was performed to investigate the immunopotentiative effects of conjugated linoleic acid on mice immunosuppressed by administratin corticoids. Mice were divided into four groups of 8 mice. Two groups (C, CP) were given diet supplemented with 1% linoleic acid (CLA) and the other two groups (L, LP) were given diet supplemented with 1% linoleic acid (LA) instead of CLA. Prednison was administered to two groups (CP, LP) for immune depression. After feeding diets for 3 weeks containing PDS injection for last 1 week. Serum and gut lumen lavage were taken. Measurement of total Ig were executed using sandwich ELISA. Serum levels of IgA, IgG, and IgM showed some trend which groups fed with CLA were higher than groups fed with LA while IgE was reduced in those fed the CLA intake, and groups administered with PDS were lower than groups administered with saline. However, no significant differences were seen in the proportion of total immunoglobulin in serum. In case of secretory IgA, Group C and CP were significantly higher than group L and LP. Especially between CP and LP, it can be seen effects of CLA. In addition that the CLA treated group weighted a significantly lower level than the one's that have not been treated with CLA. These result support the view that CLA potentiate the immune response and prevent immune depression caused by administrating of corticoids. In conclusion, CLA produced a situation favorable for immunopotentiative effects. Thus, the clinical application of CLA is warranted.
