Oral Administration of Red Ginseng Extract Promotes Neurorestoration after Compressive Spinal Cord Injury in Rats
Oral administration of RGE upregulated VEGF and Bcl-xL protein expression in damaged spinal cord at 7 and 14 days after SCI in rats. (a) Representative photographs of Western blot for VEGF and Bcl-xL proteins in spinal cord of rats before SCI and at 7 and 14 days after SCI. ß-Actin was used as an internal control for each sample. ((b) and (c)) Densitometric analyses of VEGF (b) and Bcl-xL (c) immunoreactive bands in spinal cord before SCI and at 7 and 14 days after SCI. Note that VEGF and Bcl-xL protein expressions were upregulated at 7 and 14 days after SCI by treatment with RGE. Data were obtained from five independent experiments. All values are presented as mean ± SD. , indicate significantly higher values than vehicle-treated control.
