Abstract:
Objective To study the effects of injecting recombinant human granulocyte colony stimulating factor (rhG-CSF) and basic fibroblast growth factor (bFGF) alone or combined on actue myocardial infarction(AMI).Methods AMI models were induced by ligation of the left anterior descending artery.The survived rats were divided into four groups randomly:AMI group (MI),rhG-CSF group (G),bFGF group (B),combined group (GB).Respectively,saline,rhG-CSF,bFGF,and rhG-CSF plus bFGF were injected intraperitoneally 24 h after AMI.Also,sham-operated group (S) was established with only chest-opeaned,without ligation,and no drugs intervention. The white blood cells (WBC) and mononuclear cells (MNC) proportion in peripheral blood were counted 1 week before and 1 week after the intervention,and the number of CD34+ cells was observed with immunohistochemical staining 1 week after AMI in order to compare the situation of mobilization in peripheral blood;the capillary density was evaluated by HE staining both 1 and 4 weeks after AMI;their cardiac fuction was determined in vivo,the infarction size in each group was calculated,and the pathological changes in rat myocardium were observed by HE staining 4 weeks after AMI.Results Compared with MI group,the number of WBC and MNC% in peripheral blood 1 week after AMI in G,B and GB groups were higher(P
