Purpose We investigated E-selectin expression in mice and rabbits with vinorelbine-induced phlebitis and the effect of cimetidine. To find the relationship between E-selectin expression and vinorelbine-induced phlebitis. Methods Mouse and rabbit model of vinorelbine-induced phlebitis was established by intravenous infusion of vinorelbine. Pathological observation, molecular-biological determination of E-selectin and protein function of it was evaluated. Results Grossly, we observed swelling, edema and cord-like vessel changes in mice receiving vinorelbine but only mild edema in mice pretreated with cimetidine. Pathological scoring yielded a total score of 37 for vinorelbine-treated mice and 17 for mice pretreated with cimetidine (P?ELISA revealed that rabbits treated with vinorelbine had markedly higher serum contents of E-selectin than normal saline (NS) controls (vinorelbine 1.534?±?0.449 vs. NS 0.746?±?0.170?ng/mL, P?P?P?P?E-selectin knockout mice, we found no apparent difference in tail swelling in mice receiving vinorelbine or cimetidine and vinorelbine. Conclusions In conclusion, cimetidine attenuates vinorelbine-induced phlebitis in mice probably by suppressing increased expression of E-selectin.
