OBJECTIVE: To evaluate the efficacy of Baishao Luoshi decoction (, BD) on synaptic plasticity in rats with post stroke spasticity (PSS), and to study the mechanism behind the action.
METHODS: The PSS model of rat was established by middle cerebral artery occlusion (MCAO). The neurological deficit symptoms were evaluated by modified neurological deficit score (mNSS). Muscle tension were evaluated by Modified Ashworth score (MAS). Transmission electron microscopy (TEM) was used to observe the synaptic ultrastructure. The expression of synaptic plasticity-related protein brain derived neurotrophic factor (BDNF), growth associated protein-43 (GAP43), synaptophysin (p38) and microtubule-associated protein 2 (MAP2) in the brain tissue around the infarct were detected by Western blotting.
RESULTS: We found that mNSS were significantly improved and limb spasticity was ameliorated treated by BD. The thickness of postsynaptic density and the synaptic curvature increased significantly. The expression of synaptic plasticity-related protein BDNF, GAP43, p38, MAP2 in the brain tissue around the infarct were raised remarkably after treated by BD.
CONCLUSIONS: Alleviating PSS by BD may be related to rescuing the synaptic plasticity, which provides a probable new therapeutic method for PSS.
