In the present study toxicity and immunostimulating activity of the lectin (KML-C), which was extracted from Korean mistletoe (Viscum album coloratum) were investigated in swine. To determine the toxicity, lectin was injected into thigh or cervical muscles of 4-week-old piglets (Landrace) and observed clinically and pathologically. For determinatio of the immunostimulating activity, lectin (0.7 ㎍/kg of body weight)-adjuvanted vaccine of Aujeszky's disease virus (ADV) (NYJ1-87) which was inactivated by 0.2% formalin was injected into the cervical muscle of antibody-negative piglets in the same age group.
