Sodium ozagrel SO prevents platelet aggregation and vasoconstriction in the cerebral ischemia. It plays an important role in the prevention of brain damage induced by cerebral ischemia-reperfusion. Recently, many animal studies have suggested that the Panax ginseng PG has neuroprotective effects in the ischemic brain. In this study, we assessed the neuroprotective effects that come from a combination therapy of SO and PG in rat models with middle cerebral artery occlusion MCAO. Animals with MCAO were assigned randomly to one of the following four groups: 1 control Con group, 2 SO group 3 mg-kg, intravenously, 3 PG group 200 mg-kg, oral feeding, and 4 SO + PG group. The rats were subjected to a neurobehavior test including adhesive removal test and rotarod test at 1, 3, 7, 10, and 15 days after MCAO. The cerebral ischemic volume was quantified by Metamorph imaging software after 2-3-5-triphenyltetrazolium TTC staining. The neuronal cell survival and astrocytes expansion were assessed by immunohistofluorescence staining. In the adhesive removal test, the rats of PG or SO + PG group showed significantly better performance than those of the control group Con: , PG: , SO + PG: , . Notably, the combination therapy group SO + PG showed better performance than the SO group alone SO: , SO + PG: , . In TTC staining for infarct volume, cerebral ischemic areas were also significantly reduced in the PG group and SO + PG group Con: , PG: , SO + PG: , . Immunohistofluorescence staining results showed that the group which received SO + PG group therapy had neuron cells in the normal range. They also had a low number of astrocytes and apoptotic cells compared with the control or SO group in the peri-infarction area. During astrocytes staining, compared to the SO + PG group, the PG group showed only minor differences in the number of NeuN-positive cells and quantitative analysis of infarct volume. In conclusion, these studies showed that in MCAO rat models, the combination therapy with SO and PG may provide better neuroprotective effects such as higher neuronal cell survival and inhibition of astrocytes expansion than monotherapy with SO alone.
