Both right and left facial nerve of rabbits were crashed and the degree of the injury was Sundgreeland IV. Then the injuried rabbits were devided into treatment group and the control. One week after injury

pulse electroacupuncture stimulation on acupoint (PEASA) were performed in treatment group

while the control group was left recovering naturally. The acupoints included "Yifeng" (SJ 17)

"Quanliao" (SI 18 )

"Jiache" (ST 6 )

"Dicang" (ST 4 )

" Sibai" (ST 2 )

" Yangbai" (GB 14 ) and" Hegu" (LI 4). Two weeks were a course of the treatment. When the first (3W)

second (6W) and third (9W ) course of the treatment were finished

EMG and NCV were measured respectively in both treatment and control group. Then the animals were sacrificed

facial nerve and buccal muscle tissue were collected for morphological study. As compared with the control group

the value of EMG and NCV were higher

and the morphological parameters(number and diameter of fiber

thickness of sheath) indicate the quality of regeneration were higher considerably

but the speed of axon regenerating did not increase significantly. The results of this experiment suggest PEASA promote facial nerve regeneration.
