title: The inhibitory effects of colchicine, vinblastine and cytochalasin D on lymphocyte blastogenic responses.
abstract: The inhibitory effects of colchicine, vinblastine and cytochalasin D on blastogenic responses of equine, bovine and canine peripheral blood lymphocytes (PBL) were investigated. These drugs inhibited blastogenic responses of each PBL. The concentrations for 50% recovery in PBL blastogenic response of colchicine and vinblastine were lower in equine and canine PBL than in bovine PBL. This suggested that microtubules may be more concerned in blastogenic response of equine and canine PBL than of bovine PBL. On the other hand, the concentration for 50% recovery in PBL blastogenic response of cytochalasin D was almost the same in the PBL of each animal. This meant that microfilaments made only a small contribution to the lymphocyte blastogenic response.
