Three direct electrical currents, 3mA, 5mA and 10mA were applied to the amputated hind limbs of tadpole larvae (stage number 58) of the Egyptian toad, Bufo regularis Reuss to study their effects on restoration of the regenerative ability after transection at the knee joint level. 5mA current was found to be the most enhancing one. The present results were compared with the results of earlier studies for the same stage. It is suggested that, electrical stimulation enhances limb regeneration and cartilage formation in hind limbs of a metamorphic stage (number 58) ) of Bufo regularis after transection at the knee joint level and that the strength of the electrical current needed to evoke the regenerative ability decreases along the proximodistal axis of the amputated limb.
