Three experiments were conducted investigating the interaction of dietary vanadate and mercury on the growth of chicks. The growth-retarding effect of 30 mg vanadium/kg diet was completely overcome by the inclusion of 500 mg mercury/kg diet. Restricting the feed intake of the mercury-supplemented animals to approximately those receiving vanadate alone still resulted in an amelioration of the growth retarding effect of vanadate. Analyses of femurs and kidneys revealed that mercury added to a vanadium-containing diet increased the vanadate concentration of the femur and had no effect on the vanadium concentration in the kidney. As little as 25 mg mercury/kg diet significantly reduced the growth retarding effect of vanadium. The inclusion of 100 mg mercury/kg in the diet resulted in a significant increase in renal glutathione concentration.
进行了三项实验，研究膳食钒酸盐和汞对雏鸡生长的相互作用。每千克日粮中添加30毫克钒的生长抑制作用可通过每千克日粮中添加500毫克汞而完全克服。将补充汞的动物的采食量限制在仅接受钒酸盐的动物的大致采食量水平，仍可改善钒酸盐的生长抑制作用。对股骨和肾脏的分析表明，在含钒日粮中添加汞会增加股骨中的钒酸盐浓度，而对肾脏中的钒浓度没有影响。每千克日粮中低至25毫克汞就能显著降低钒的生长抑制作用。日粮中每千克添加100毫克汞会导致肾脏谷胱甘肽浓度显著增加。
