This study investigates the effect of puerarin (PR) on peripheral nerve regeneration in vitro and in vivo. PR at concentrations of 1, 10, and 100μM significantly promoted survival and outgrowth of cultured Schwann cells, as compared to the controls treated with culture medium only. in vivo study, peripheral nerve regeneration was evaluated across a 15-mm gap in the sciatic nerve of rats using a silicone rubber nerve chamber filled with PR solution. The control group chambers were filled with normal saline only. At the end of eight weeks, animals in the PR groups, especially at a concentration of 1 μM, had a significantly higher density of myelinated axons, greater evoked action potential area, and a larger nerve conductive velocity,as compared to the controls. All experimental results indicate that PR treatment promotes nerve growth and is a promising herbal medicine for recovery of regenerating peripheral nerves.
