骨矿含量与肾虚、肾主骨关系的研究

Bone mineral content and kidney-astkenia

采用ＳＤ１０００型骨矿物仪测定１～８８岁３５８１例健康查体者的骨矿（骨钙）含量，其中无肾虚者３０７９人，肾虚者５０２人。结果，女性３５岁、男性４０岁以前骨钙含量随年龄增长而增加，呈显著正相关；女性３６岁，男性４１岁以后骨钙含量随年龄增长而下降，呈显著负相关；肾虚者骨钙含量明显低于健康者，年龄与骨钙含量呈显著负相关。骨钙含量的增减变化与肾精气之盛衰有密切关系。本研究结果支持“肾主骨”理论。

Bone mineral density (BMD) was measured in 358l people with bone mineral detecting apparatus model SD-1000. Of them 3079 people had no evidence of kidney-asthenia while 502 had kidney-asthenia. Results showed that BMD was markedly positively correlated with increment of age in females aged under 35 years or males under 40 years, but was markedly inversely correlated with age in females older than 35 years or in males older than 40 years. BMD was markedl y decreased in people with kidney-asthenia compared with people with out. The incidence of kidney-athenia was increased with age in both sexes, and was negatively correlative to BMD. The association of decrease or increment of BMD with 'kidney'function supports the theory of traditional Chinese medicine that 'kidney masters bones'.
