RESUMO

Objective To investigate the expression of proliferating cell nuclear antigen(PCNA),vascular endothelial growth factor(VEGF) and microvessel density(MVD) in squamous cell carcinoma;and to explore the relationship between their expression and tumor biological behavior.Methods The expressions of PCNA,VEGF and MVD were analyzed by immunohistochemical method in 71 cases of esophageal squamous cell carcinoma.Results The intensity positive rate of PCNA indicated close relationship between cell differentiation and lymph node metastasis(P

RESUMO

AIM: To investigate the correlation between the signal pathway of IKK/NF-?B and the anti-oxidant activity in asthmatic rats and the modulation of Ginkgo biloba extract (Egb). METHODS: Thirty-six male SD rats were randomly divided into three groups: control group (group C), asthmatic group (group A) and Egb group(group E). Asthma in rats was established by ovalbumin (OVA) challenge methods. The mRNA of IKK? and the protein of NF-?B P65 in lung tissue were assessed by using in situ hybridization with oligonucleotide probe and immunohistochemisty, respectively. RESULTS: The expression of IKK? mRNA and NF-?B P65 protein in group A were significantly increased when compared with group C (P
