缺铁大鼠耳蜗组织铁降低对耳蜗听功能的影响
Iron decrease on auditary function of cochlear tissue in irondeficient rats
摘要
Abstract
Objective To determine the iron concentration in cochlear tissue and serum of iron - deficient rats and changes in auditory
thershole. Method The determination of iron concentration in cochlear tissue and serum were assessed by atomic absorptin spectrophotometryafter reconstruction of iron-deficient rats. Results The concentration of iron in serun of iron - deficient group and normal group are( 14. 93 ±9. 72) μ mol/L、 (46. 11 ± 18. 3) μ mol/L. The iron concentration in cochlear tissue of iron - deficient group and normal group are ( 179. 80 ±24. 70) pmol/l, (410. 18 ± 111.96) pmol/L. Auditory threshold incresed by 15 db or more was more common in iron -dificient group comparedwith control group. Conclusion The concentration of iron in cochlear tissue and serum of iron - deficient rats are blow affecting auditory functionof cochlear tissues.关键词
