燃煤型地氟病区家猪氟中毒趾骨病理及形态计量学研究

Histopathologic and Bone Histomorphometric Studies of Pigs, Phalanges in an Endemic Fluorosis Area

采用病理组织学，骨计量学方法对地氟病区和非病区家猪趾骨进行比较性研究。结果显示：病区血、尿和骨氟的含量明显增高，而血钙显著降低，组织病理学检查和形态定量分析，可见家猪趾骨以骨质疏松占优势。

This paper presents the histopathologicchanges and bone histomorphometry of ten pigs’pholanges in an endemic fluorosis area. Ten pigs fromnonendemic area served as control,Results showedthat the fluoride contents of blood,urine and bonewere markedlv increased and the calcium contents ofNood were markedly decreased in endemic pigs thantkose in nonendemic ones. Histopathologic and bonemorphometric studies of the phalangeal bones of pigsfrom endemic area indicate that osteoporosis is the pre-dominant change.
