煤矿工人动脉粥样硬化的病理学研究

Pathological Study on Arteriosclerosis of Coal Miners

对１４４例煤矿工人主动脉、心脏和冠状动脉的尸检材料进行了分析，胸主动脉经苏丹Ⅳ染色后，用描图称重法分别计算出不同ＡＳ病变区百分比和ＡＳ病变指数。结果表明：煤工尘肺患者与无尘肺病组间ＡＳ病变指数的差异有显著性（Ｐ＜００５），煤矿工人胸主动脉粥样硬化明显重于同年龄组的非煤矿工人。通径分析显示，煤矿工人的ＡＳ病变与年龄有直接的联系，与接尘工龄和工种无关，但尘肺的严重程度对其有一定的促进作用。

coal miners were autopsied for aorta,coronary artery and heart.The percentage of different arteriosclerosis(AS)area and AS indicator of thoracic artery stained by Sudan were calculated by tracingweight method.The results showed that significant difference( P <005)of AS indicator existed between pneumoconiosis and nonpneumoconiosis.The thoracic AS of coal miner was more serious than nonminers.Path analysis showed that AS was correlated directly with the age and not correlated with the workingage and job type,but the severity of pneumoconiosis would promote the AS formation.
