Objectives : This study was aimed to investigate the therapeutic effect of Bogijetongtanggammi-bang (BJTG) on injury of the peripheral nerve tissues. Methods : Rats were divided into 2 groups. The rats of the first group were injected with Taxol (1.25 mg/kg) to their sciatic nerves, once each. The sciatic nerves of the rats of the second group were crushed by forcept for 30 seconds. Rats were administered with BJTG (400 mg/kg) or 0.9% saline for 5 days. Changes of DRG neurons, Schwann cells, Cdc2, caspase 3. phospho-p44/42 Erk1/2, phospho-vimentin and ${eta}1$ integrin were observed by fluorescent microscope and analysed in western blot. Results : In Taxol-treated SD rat models, BJTG up-regulated neurite outgrowth, Schwann cells, Cdc2 and phospho-Erk1/2, and down-regulated caspase 3. In pressure-injured rat models, BJTG up-regulated axons of sciatic nerve, Schwann cells, Cdc2, phospho-vimentin, ${eta}1$ integrin, and down-regulated caspase 3. Conclusions : Taken together, BJTG was promotive of nerve regeneration on SNI as well as Taxol-induced nerve injury. BJTG had a pharmaceutical property enhancing recovery of injured peripheral nerves and could be a candidate for drug development after further research.
