Effect of Roucongrong (Herba Cistanches Deserticolae) decoction on the substantia nigra through Wnt/β-catenin signaling pathway in rats with Parkinson's disease induced by 6-hydroxydopamine hydrochloride.

Objective: To investigate the effect of Roucongrong (Herba Cistanches Deserticolae) decoction on the substantia nigra in rats with Parkinson's disease (PD) induced by 6-hydroxydopamine hydrochloride (6-OHDA). To further determine whether the Wnt/β-catenin signaling pathway is involved in the action.

Methods: A rat model of PD was established by intracranial injection of 6-OHDA.
