缺血性脑血管病患者血钙和骨密度测定及相关性研究

Serum calcium content and bone density in patients with ischemic cerebrovascular disease

用单光子骨密度仪和自动生化分析仪分别对５７例脑梗塞、５４例脑动脉硬化及１００例健康查体者的骨密度和血钙进行了检测，并对他们之间的相关性进行了探讨。结果发现脑梗塞组和脑动脉硬化组血清钙和骨密度含量均明显低于健康对照组，老年组又低于老年前期组，且骨密度含量随血钙降低而明显降低（呈正相关）；在健康组中，血钙及骨密度含量老年组和老年前期组均明显低于青壮年组。在各相应年龄组中，血钙降低幅度又以脑梗塞更明显。提示血钙和骨密度水平随年龄增长而降低，而骨密度又随血钙低而降低。

The serum calcium content and bone density in 57 cases of cerebral infarction, 54 cases of cerebral arteriosclerosis and 100 cases of normal controls were measured by using single photon bone densitometry and a u lob toe he moanal yti caf devi ce, respectively. The results showed that the serum Ca2+ content and bone density in the cerebral infarction group and arteriosclerosis group were significantly lower than that in normal controls lthat in aged group was lower than that in pre-aged group land with the decrease of serum Ca2+,the bone density decreased significantly. In normal controls,the serum Ca2+ content and bone density in aged group and pre-aged group were significantly lower than those in young adult group. Among all groups,the decrease of serum Ca2+was the most obvious in infarction group. The data indicate that the serum Ca2+content and bone density decreased with aging,and on the other hand,the bone density decreased with the decrease of serum Ca2+.
