Chinese herbal compound Jinsiwei improves synaptic plasticity in mice with sporadic Alzheimer's disease induced by streptozotocin.

Objective: To investigate the efficacy of Jinsiwei (a patented Chinese herbal compound) on learning and memory impairment, the number of synapses and synaptic plasticity-related structural and functional protein expression in mice with sporadic Alzheimer's disease (SAD) induced by streptozotocin.

Methods: Seventy-five C57/BL6J male mice were intracerebroventricularly injected with streptozotocin to establish the animal model of SAD. Mice were randomly divided into the model group (MG), donepezil group (DG), and the Jinsiwei high, medium, and low-dose groups (JH, JM, JL).
