补锌对颌面骨折后血锌含量影响的比较研究

A comparative study of effects of zinc on serum zinc concentration during maxillofacial fracture healing.

通过对１２只实验性颧骨骨折新西兰兔在骨折愈合初期采用补锌和未补锌两种处理方法，来比较研究两组在不同时期血锌含量的变化。结果表明：术后第１天，两组血锌含量均显著下降（Ｐ＜０．０５），对照组第３天仍明显低于术前（Ｐ＜０．０５），而实验组则明显升高，与术前相比，差异不显著（Ｐ＞０．０５）。后期两组曲线变化基本相同，但实验组在各时期血锌含量均高于对照组。提示：补锌可维持血锌含量在高水平。

Twelve New Zealand Rabbits with maxillofacial fractures were studied in order to investigate how effects of zinc on serum zinc concentration during fracture healing. The results showed that: Serum zinc concentration decreased significantly in two groups on the lst day( P <0.05). The control group remain significantly decreased on the 3rd day( P <0.05),while the experimental group increased gradually and return to normal level and the difference was not markedly compared with the preoperatively ( P >0.05). The serum zinc line in two groups is likely the same in the afterward, but the concentration in experimental group is lasted higher than those of in control group. It implies that extra zinc supplement in early days can maintain the serum zinc concentration in high level, and can improve the fracture healing.
