[Analgesic effect of Corydalis yanhusuo in a rat model of trigeminal neuropathic pain].

Objective: To evaluate the analgesic effect of Corydalis yanhusuo on trigeminal neuropathic pain.in a rat model.

Method: Rat model of trigeminal neuralgia pain were established by inducing chronic constriction injury (CCI) of the infraorbital branch of the trigeminal nerve (ION).

[Expression and activity of Cdk5/p39 during rats Vc development].

Purpose: To evaluate the different expression of Cdk5 two activators, p35 and p39 throughout rats Vc development.

Methods: The changes of Cdk5 activity, expression of Cdk5 and p39 in the development in spinal trigeminal subnucleus caudalis(Vc) were studied by Western blotting, immunoprecipitation and kinase assay. Statistical analysis was performed using SPSS11.
