Comparison of immunohistochemical score of NF-κB and TNF-α in brain tissue.

Group	NF-κB	TNF-α
Sham-surgery	3.2±0.5	1.8±0.4
Model	5.6±0.4a	5.2±0.7b
GLGZD-1	4.8±0.5	4.6±0.2
GLGZD-2	4.4±0.6c	4.4±0.7d

^aP<0.05,

^bP<0.01, vs. sham-surgery group;

^cP<0.05,

^dP<0.01, vs. middle cerebral artery occlusion model group. TNF, tumor necrosis factor; GLGZD, Gualou Guizhi decoction; NF, nuclear factor; GLGZD-1, rats that were administered 7.2 g/kg GLGZD; GLGZD-2, rats that were administered 14.4 g/kg GLGZD.
