放射性豚鼠咽鼓管損傷的初步研究
發(fā)布時間:2021-03-05 08:00
目的:本研究通過建立放射性咽鼓管損傷動物模型,觀察轉(zhuǎn)化生長因子-β1(TGF-β1)、基質(zhì)金屬蛋白酶-9(MMP-9)及基質(zhì)金屬蛋白酶抑制劑-1(TIMP-1)在豚鼠咽鼓管中的表達(dá)情況,探討它們在放射性咽鼓管損傷的發(fā)病及病程進(jìn)展等方面的作用及意義。方法:選用健康成年豚鼠44只分為40只為照射組和4只對照組。照射組一次性給予右耳70Gy60Coγ射線照射,照射結(jié)束后第7天、第14天、第30天、第60天及第90天分別處死動物各8只;對照組4只未進(jìn)行照射。動物處死后立即取咽鼓管固定,行咽鼓管切片,HE染色觀察病理學(xué)變化,Masson染色觀察咽鼓管膠原纖維的表達(dá)變化, SP免疫組織化學(xué)法檢測咽鼓管TGF-β1、MMP-9和TIMP-1蛋白的表達(dá)變化。結(jié)果:(1)大體觀察:照射后第7天組外耳道及鼓膜未見明顯異常改變,第14天組見外耳道皮膚出現(xiàn)少量潰瘍,部分動物外耳道口有較清的液體流出,部分動物見聽泡壁濕潤,中耳腔少量滲出液,鼓室黏膜充血,鼓膜無穿孔。隨著時間的延長,照射組外耳道皮膚潰瘍加重,外耳道口積液越來越多,最后堵塞外耳道口。照射后第30天組鼓膜穿孔,聽泡內(nèi)有積液或膿性分泌物。照射后第60、...
