Abstract:
Objective To investigate the effect of low-dose hydrocortisone(HC)on hippocampus nuclear factor kappa B((NF-?B)),I?B expression in lipopolysaccharide(LPS)induced septic rats and the role of NF-?B signal transcription pathway in pathogenesis.Methods Fifty-four rats were randomly divided into 3 groups: control group(A group,n=6),model group(B group,n=24),low-dose HC treatment group(C group,n=24).The septic rat model was established by intraperitoneal injection LPS(1 mg/kg),as the intervention by caudal vein injection low-dose HC(6 mg/kg),each of B and C group was subdivied into 2,8,16,24 hours respectively after LPS injection(n=6).At serial time points,the animals in each group were sacrificed,brain tissue samples were harvested to determine NF-?B,I?B expression by immunhistochemistry in hippocampus.Results In B group: NF-?B expression was up regulated compared with A group(P
