OBJECTIVE
To investigate the influence of aqueous extract of Aralia echinocaulis Hand.-Mazz on the expression of fracture healing-ralated factor receptors.
METHODS
Single factor model was set up in SD rat. Selecting 14 and 28 days in the experiment. Immunohistochemistry was employed to determine the expression of Fibroblast growth factor receptor 2 (FGFR2), Fms-like tyrosine kinase (Flt-1) and Fetal licer kinase (Flk-1) at 14 and 28 days after model establishing.
RESULTS
The expression of Flt-1 and Flk-1 at 14 days (the latter was more remarkable) were obviously promoted in High dose group of aqueous extract of Aralia echinocaulis Hand.-Mazz, and higher than that in normal group and model group. The expression of FGFR2 in the high dose group of Aralia echinocaulis Hand -Mazz was also promoted visibility, close to that in the compare group (traditional Chinese medicine), but higher than than in the model group. There was no significant difference among them. At 28 days, the expression of FGFR2, Flt-1 and Flk-1 in all groups decreased except normal group, and got higher expression in model groups than each control groups.
CONCLUSIONS
Aqueous extract of Aralia echinocaulis Hand.-Mazz can promote angiogenesis in fracture healing, improve the activity and aggregation of fibroblasts, osteoblasts and chondrocytes. It also helps to quicken ossification in the cartilage and promote fracture healing.
