    Abstract:
    During the process of electroacupuncture (EA) therapy, whether there being a corrosive effect in ac- upuncture needles was observed. Acupuncture needles were inserted into a rabbit's acupoint to perform a 12-hour electrical stimulation with three types of common EA waveform; additionally two needles were put in 0.9% sodium chloride solution with 12-hour direct current. Afterwards, environmental scanning electron microscope was applied to detect the surface physical characteristics of acupuncture needles. As a result, after a 12-hour continued electri- cal stimulation with three types of common EA waveform in the rabbit, there was no corrosive effect in acupunc- ture needles; but the direct current could cause severe corrosion in acupuncture needles. It is believed that there is no corrosion effect on acupuncture needles in current EA treatment, and some accidents reported in literature may be related to quality of EA device or improper manipulation during the treatment.
