原子吸收分光光度法测定健康犬血清和肝脏锌、铜含量

用原子吸收分光光度法测得42只健康成龄犬的血清锌含量为14.8±2.0mmol/L,血清铜含量为13.6±.7mmol/L;29只犬的肝锌含量为2.4±0.4mmol/g(干重),肝铜含量为2.8±1.0mml/L(干重)。血清及肝脏锌、铜含量均无明显性别差异。血清锌与肝锌含量间呈正相关,血清铜与肝锌铜含量无明显相关。在一般喂养条件下犬血清锌、铜波动不大。增加锌摄入量可使血清锌和肝锌水平迅速上升,血清铜水平迅速下降,而肝铜变化迟缓。

Measurement of Zinc and Copper in Serum and Liver by Atomic Absorptinn Spectrophotometry in Dogs

The concentrations of zinc and copper in serum were measured by ato-mic absorption spectrophotometry in 42 health adult dogs. The mean values Were 14.8±2.0m.nol/L and 13.6±2.7mmol/L respectively. Liver zinc and co-pper were measured in 29 health dogs, and the mean values were 2.4±0.4 mmol/g d. w. and 2.8±1.0mmol/g d. w. respectively. There was no significant difference between the two sexual groups in serum and liver zinc and copper values. In normal fed dogs, there were little changes in serum zinc and co-pper. As feeding large amount of zinc, the level of serum and liver zinc elevated quickly and serum copper decreased simultaneously, while the li-ver copper remained unchange.
