Objectives: Acupuncture treatment has been clinically used for functional recovery in Parkinson’’s disease. In the present study, we investigated the effect of acupuncture at Zusanli (ST36) on nigrostriatal dopaminergic neuronal cell death in rats.
Methods: A Parkinson’’s disease model was induced by the unilateral injection of 6-hydroxydopamine (6-OHDA) into the striatum. Acupuncture treatment was performed at Zusanli (ST36) and at the hip, as a non-acupoint, once a day for 14 days. Two weeks after 6-0HDA injection, an apomorphine-induced rotational behavior test showed significant rotational asymmetry in rats with Parkinson’’s disease. Immunostaining for tyrosine hydroxylase demonstrated a dopaminergic neuronal loss in the substantia nigra and dopaminergic fiber loss in the striatum.
Results: Acupuncture at the ST36 acupoint significantly inhibited rotational asymmetry in rats with Parkinson’’s disease, and also protected against 6-OHDA-induced nigrostriatal dopaminergic neuronal loss. These effects of acupuncture were not observed for non-acupoint acupuncture.
Conclusions: The present study shows that acupuncture treatment, especially at the ST36 acupoint, can be used as a useful strategy for the treatment of Parkinson’’s disease.
