This study was carried cut to determine the immunological response of uterus-induced by Lipopolysaccharides (LPS) in Holstein cows. The LPS isolated from Bacteroids helcogenes and Fusobacterium varium was injected at the rate of 100 ㎍ with 30 ml of phospahte buffer saline (PBS) in each cow(n=5). Three cows were acted as control. There was no difference in total polymorphonuclear leukocytes (PMNL) concentration in uterine fluid between control and LPS groups at 24, 48 and 72 hrs after LPS treatment. There was significant difference in rate of PMNL between control and LPS groups at 24(41.7% vs 72.1%), 48(41.0% vs 81.6%) and 72 hrs (44.3% vs 79.0%) after LPS treatment.
