Abstract: 为探讨铝氟联合作用时铁与矿物代谢的关系,在鸡铝氟病及铝危害模型基础上对全血铁和骨铁用 AAS法进行了检测.结果表明,性成熟前各实验组全血铁均升高,但以加氟组更为明显;性成熟后饲料加入氟化物的 3个组全血铁仍高于对照,未加的另3个组则低于或接近对照组.骨铁含量均有所下降.饲氟、骨氟、骨铝与全血铁有明显正相关(P<0.2)或显著正相关(P<0.05),与骨铁有明显负相关,差异均有显著或非常明显(P<0.1) 意义.全血铁与全血钙、镁、磷,骨灰化率、骨矿含量、平均骨壁厚度、骨矿沉积率均呈显著正相关.骨铁与骨钙、镁呈显著或明显负相关,与成骨细胞指数、破骨细胞指数、类骨质体积呈明显或非常显著(P<0.01)负相关,与骨单位吸收周期呈明显正相关.全血铁与骨铁呈明显负相关.提示,全血与骨骼铁代谢是能分离又相对应的体系,可能有相互平衡、调节和补偿作用.铁不仅是血红蛋白的必需成分,还与骨矿化和骨细胞及矿物元素有密切关系.
