成人及新生儿颅骨铜和锌含量的初步研究

PRELIMINARY INVESTIGATION OF COPPER AND ZINC CONTENT IN ADULT AND NEWBORN SKULL

本文系用原子吸收光谱法测定了西安地区10例成人尸体和15例新生儿尸体的颅盖骨内Cu和zn的含量。结果求得成人颅骨中Cu正常含量(均数±标准差)为4.48±3.78mg/kg(干组织重);zn为597.05±472.54mg/kg。新生儿颅骨中Cu和zn的含量分别为1.96±0.76mg/kg;1160.38±859.71mg/kg。结果表明,成人颅骨内Cu含量高于新生儿,而成人颅骨内Zn含量显著低于新生儿。

The present paper reports a determination of copper and zinc in skulls (10 adult stulls and 15 newborn skulls) in Xi'an area by atomic absorption spectrophotometry. The results showed that the normal content of copper in the adult skulls was 4.48± 3.78 mg/kg dry tissue, zinc 597.05 ± 472.54 mg/kg. In the newborn skulls, the normal contents of copper and zinc were 1.96 ± 0.76 and 1160.38 ±859.71 (mg/kg dry tissue), respectively. These results indicate that the copper contents in adults skulls are higher than in newborn infants and the zinc contents in adults skulls are lower than in newborn obviously.
