[Expression and significance of enkephalin and dopamine in experimental rat cerebral concussion tissue].

Aim: To explore the expression and significance of enkephalin and dopamine in rat cerebral concussion tissue.

Methods: 80 Wistar male rats were used to make animal model of cerebral concussion, which were sacrificed on 1,3,7,14 and 30 days after postconcussion and the brain tissues were taken out. The expression patterns of enkephalin and dopamine were studied in the course of cerebral concussion by immunohistochemical staining.

[Study on the expressions of basic fibroblast growth factor and nervous growth factor genes in rat cerebral concussion].

Objective: To study the expressions of basic fibroblast growth factor (bFGF) and nervous growth factor(NGF) genes in rat cerebral concussion.

Methods: Eighty Wistar male rats were used for animal model of cerebral concussion, which were sacrificed on 1, 3, 7, 14 and 30 days after injury and the brain tissue was taken out. The expressions of bFGF and NGF genes were studied in the course of cerebral concussion by means of immunohistochemistry and in situ hybridization.
