ABSTRACT
Objective To observe the protection effect of thrombopoietin on adriamycin-inducod acute myocardium injury in rats model.Methods 32 Wistar rats were randomized into four groups (n=8)Control group,ADM group,ADM +TPOL group and ADM +TPOH group.All agents were given by intraperitoneal injection.The control group was given normal saline,while the other three groups were given adriamycin at the dosage of 20 mg/kg once.TPO groups were injected TPO at different dosages of 10 μg/kg or 30 μg/kg three times on alternate days.ELISA was used to detect CK-MB and cTnI content of serum in the rats.By HE staining,pathological change was found and grade of tissue morphology was scored.The ultrastructure change of cadiocyte was observed by the electron microscope.Results The energy of CK-MB (14.65±1.91,14.21±1.70) and cTNI (9.66±1.31,10.07±1.20) in TPO groups were obviously lower than that of the ADM group(19.58±3.49,12.50±1.62) (P<0.05),respectively.Pathological score of ADM group was higher than TPO groups (P<0.01).The ultrastructure of myecard tissue in the ADM group was damaged more severely than TPO groups.Above-mentioned indexes were with no significant difference between ADM+TPOL group and ADM+TPOH group.Conclusion TPO can protect the heart which was injured by the ADM.
