Abstract: OBJECTIVE: To investigate the effect of Duyiwei ( lamiophlomis rotate) capsule on the expression of proliferating cell nuclear antigen (PCNA) in Wistar rats. METHODS：40 Wistar rats，half male half female，were randomly divided into 5 groups：model group，PTCA group，Duyiwei (Lamiophlomis rotate) capsule 0.50，1.25，2.50 g/kg，positive control group (salvia miltrorrhiza tablet 1.0 g/kg) . Oral administration of drugs was performed in each group，continuously 5 days. Then all rats were treated by percutaneous transluminal coronary angioplasty (PTCA) for the establishment of carotid balloon injury model. Then drug treatment continued after PTCA for 28 days. Carotid artery segment underwent routine biopsy immunohistochemistry and PCNA expression determination. RESULTS：In the normal artery，these was low level or no expression of PCNA. In the arterial intima of the model groups，33.71% was PCNA-positive with each dose of Duyiwei capsule group showing significant differences (P <0.05). CONCLUSION： Duyiwei capsule significantly inhibited the expression of PCNA， which may be one of its mechanisms in preventing restenosis after carotid artery injury in rats.
