目的 探讨铀矿尘致大鼠纤维化过程中Ⅰ、Ⅲ型胶原、层粘连蛋白(Laminin,LN)表达的变化特征.方法 60只Wistar大鼠随机分为铀矿尘组(30只)和对照组(30只),铀矿尘组大鼠一次性非暴露气管内滴注20 mg/ml的粉尘悬液1 ml,对照组大鼠一次性气管内滴注生理盐水1 ml,分别于处理后7、14、21、30及60 d每组随机处死6只,取肺组织,HE染色观察肺组织形态学改变,天狼猩红染色法观察肺组织Ⅰ、Ⅲ型胶原变化,免疫组织化学法检测LN蛋白的表达.结果 铀矿尘致肺组织纤维化过程中可见Ⅰ、Ⅲ型胶原的大量增生,染尘后早期主要以Ⅰ型胶原增生为主.铀矿尘组21、30、60d时Ⅰ型、Ⅲ型胶原纤维面积百分比明显增高,与对照组比...

To explore the characteristics of LN and type I, III collagen in pulmonary fibrosis induced by uranium ore dust in rats. 60 adult Wistar rats were divided randomly into two groups, control group (30 rats) and uranium ore dust group (30 rats). Non-exposed intratracheal instillation method was used. Uranium ore dust group was exposed 20 mg/ml uranium ore dust suspension 1ml per rat, meanwhile control group was exposed normal saline 1ml per rat. Post-exposed the 7, 14, 21, 30 and 60 d, 6 rats in each group were killed randomly, lung tissue were collected. The pathological changes in lung tissue w...
