title: [Expression of nuclear factor-kappa B p65 in hyperlipemia model of mice].
abstract: OBJECTIVE
  To study the expression of nuclear factor kappa B p65 in hyperlipemia model of mice, and the relationship between hyperlipemia and deaf.
  
  
  METHODS
  Twenty mice were divided into two group. The hyperlipemia diet group was established in ten mice,and the normal diet group was served as normal control. Six weeks later, immunohistostaining was used to detected the express of NF-kappa B p65 in all mouse cochlear. ABR threshold was obtained from both normal group and hyperlipemia group.
  
  
  RESULTS
  Immunoreactivity NF-kappa B p65 in mouse cochlea of hyperlipemia was localized in the organ of Corti, tectorial membrane, stria vascularis, spiral ligament, spiral ganglion and nerve fibers. The NF-kappa B p65 expression was markedly increased in mouse cochlea of hyperlipemia ABR threshold was significant difference between hyperlipemia group mice and control group mice (P < 0.01).
  
  
  CONCLUSIONS
  The expression of NF-kappa B p65 in mouse cochlea can be induced by hyperlipemia. And ABR threshold increased in hyperlipemia group mice. This shows that hyperlipidemia can damage acouesthesia of mice.
