在不添加和添加果糖的稀释液中，研究了锌和His(一种锌螯合剂)对火鸡精子吸氧的影响。在不含果糖的稀释液中加入0.5 mM的锌，精子的O2摄取率明显低于单独加入稀释液或含3 mM His的稀释液中的精子，但不会降低精子的受精率。His对精子吸氧无影响。在含1 mM果糖的稀释液中，含锌的精子氧摄取量明显低于单独使用稀释剂或含His的稀释液。在体内，锌可能对精子吸氧起到了调节作用。
The effect of Zn and His (a Zn chelator) on O2 uptake by turkey sperm was examined in diluents without and with added fructose. The presence of 0.5 mM Zn in a diluent without fructose depressed sperm O2 uptake significantly below that of sperm in diluent alone or in diluent with 3 mM His but did not depress sperm fertility. His had no effect on sperm O2 uptake. Sperm O2 uptake in diluents containing 1 mM fructose was significantly less in the presence of Zn than in diluents alone or in diluent with His. Zn may have played a regulatory role in sperm O2 uptake in vivo.
