Cerium, a lanthanide, is the most abundant rare earth element present in monazite and is biologically active. It has been postulated that cerium toxicity in conjunction with magnesium deficiency causes tropical endomyocardial fibrosis, a restrictive human cardiomyopathy (Valiathan et al. 1989; Valiathan and Kartha 1990). Generally, lanthanides are known to be poorly absorbed (Durbin et al. 1956; Evans 1990). The present study was carried out to ascertain whether magnesium deficiency promotes accumulation of cerium in various organs of rats.
铈是一种镧系元素，是独居石中含量最丰富的稀土元素，且具有生物活性。据推测，铈的毒性与镁缺乏共同作用会导致热带心内膜心肌纤维化，这是一种限制性人类心肌病（瓦利亚坦等人，1989年；瓦利亚坦和卡尔塔，1990年）。一般来说，已知镧系元素的吸收率很低（德宾等人，1956年；埃文斯，1990年）。本研究旨在确定镁缺乏是否会促进铈在大鼠各器官中的蓄积。
