tokens: The distance travelled by leukocytes before arrest on 30 mM glucose , or on IL-1beta-treated endothelial cells , was significantly ( P < 0.01 ) higher than that observed for leukocytes adhering on control endothelium ( 30 mM glucose : 76.7+/-3.5 ; IL1beta : 69.7+/-4 versus 5 mM glucose : 21.5+/-5 microm ) .
