Pain behavior was observed. By using immunofluorescence histochemistry, expressions of glial fibrillary acidic protein (GFAP) and OX42, which are makers for astrocyte and microglia, respectively, in dorsal commissural nucleus (DCN) was detected.

• 观察大鼠痛行为表现后,应用免疫荧光组织化学方法观察内脏痛大鼠骶髓后连合核(dorsal commissural nucleus,DCN)内星形胶质细胞的标记物胶质原纤维酸性蛋白(glial fibrillary acidic protein,GFAP)和小胶质细胞的标记物OX42的表达变化。
