本实验研究了在正常、功能不足、功能过度的情况下铅对大鼠切牙萌出的影响。在实验第 32天时处死动物。注射醋酸铅溶液后功能不足组大鼠切牙萌出比对照组的要慢 (P <0 .0 5 )。研究结果显示了以前曾报道的重金属铅的毒性作用
The present study investigated the effect of lead on edentulous rat incisors under normal, hypofunction and over-functioning conditions. The animals were sacrificed on the 32nd day of the experiment. After injecting lead acetate solution, the function of incisors in rats was slower than that in control group (P <0.05). The results show previously reported toxic effects of heavy metal lead
