Analysis of Bone Mineral Content in Human Cases of Endemic Skeletal Fluorosis with Different Types of Roentgen Rays
Tian Jian-yin, et al (Zhangjiakou Institute of Endemic Disease Control, Hebei Province, China)
Scan over a ulna and radious of left anterior arm through a 125I photon beam was made for determination of their bone mineral contents among 128 cases of endemic skeletal fluorosis. The results showed that the bone mineral content of the cases was lower than that of normal controls. It was also found that, even among the cases of endemic skeletal fluorosis, their bone mineral contents varied with their four types of roentgen rays (early osteopathic changes, osteosclerosis, osteoporosis and mixed osteopathic changes), bone mineral contents being arranged, in order from high to low levels, as follows: osteosclerosis early osteopathic changes mixed osteopathic changes osteoporosis.
