摘要

AIM:To investigate effect of recombinant human thrombopoietin on exsanguine thrombocytopenia mice. METHODS:Normal peripheral platelet counts were performed on sample obtained from the tail vein of purebred Babl/c mice including experimental and control groups before experimentation. rhTPO was injected into the mice by intraperitoneal injection once a day for 7 days. On the seventh and the fourteenth day, the mice were phlebotomized from the supra-obitalis vein in order to make exsanguine thrombocytopenia animal model. At the same time, we observed the biological activity of recombinant human thrombopoietin in vivo and the mice's death rate. RESULTS: On the seventh day and the fourteenth day, platelet counts of mice treated by rhTPO were higher than those by PBS (P＜0.05). Moreover the platelet counts of mice in experimental group of rhTPO showed increasing tendency following experimental days. In addition, death happened in two groups after those mice were phlebotomized from the supra-obitalis vein, but the death rate in negative control group was evidently higher than that in experimental group (P＜0.05). CONCLUSION:rhTPO had obvious biological activity in increasing platelet production, which resulted in the drop in thrombocytopenia mice's death rate.
