Nuclear factor-kappa B (NF-kappa B) plays an important role in secondary damage after intracerebral hemorrhage (ICH). We explored NF-kappa B activation and the relationship between NF-kappa B and cell death in the perihematomal brain tissue of patients after ICH. According to the interval between onset of hemorrhage and specimen collection, 53 cases of patients with basal ganglia hemorrhage were divided into six experimental groups: 0-6, 7-12, 13-24, 25-48, 49-96, and > 96 h group. Brain tissues of the experimental groups and control group were collected. IL-1 beta, TNF-alpha, and NF-kappa B p65 expressions at the protein level were detected by immunohistochemistry. Cell death was detected by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay. All of the detection items of immunohistochemistry and TUNEL showed significant differences between the experimental groups and control group. At the protein level, nuclear NF-kappa B p65, IL-1 beta, and TNF-alpha achieved maximum values at 13-48, 0-24, and 13-48 h, respectively. Maximum cell death was reached at 13-48 h. NF-kappa B activation increased dramatically in perihematomal brain tissue after ICH. NF-kappa B activation was closely related with cell death and had an important function in secondary brain damage after ICH in patients.
