作者为了闸明镉中毒引起骨质和肾脏损害之间的关系,对实验性镉中毒大鼠的骨质和肾脏进行了形态学的观察。实验用刚断乳,体重约50克的雄性大鼠,分为两大组。第一大组喂饲三周经过精制的“含镉正常饲料”,这种饲料含0,45%钙、0.3%磷和生理量的维生素 D_3(6.25ug/100克食物),饲料中还分别含有含镉量为0,10,30,100和300ppm 的氯化镉, In order to clarify the relationship between bone mineral and kidney damage caused by cadmium poisoning, the morphological observation of bone and kidney of experimental cadmium poisoning rats was performed. Weaned rats weighing approximately 50 grams were divided into two groups. The first group was fed a refined “normal diet containing cadmium” for three weeks. This diet contained 0,45% calcium, 0.3% phosphorus, and a physiological amount of vitamin D 3 (6.25ug/100g food). Contains cadmium chloride with cadmium content of 0, 10, 30, 100 and 300 ppm,
