作者试图阐明镉中毒、缺钙、肾衰和骨病之间的关系。实验用雄性大鼠,分为四组,每组五只,给予不同的饲料和饮水。1组给足钙饲料和蒸馏水(对照);2组给缺钙饲料和蒸馏水;3组给足钙饲料和含镉50 ppm的水;4组给缺钙饲料和含镉50 ppm的水。逐日测量饲料和饮水量。120天后处死动物,作组织学和生化学检查。对照组生长良好,缺钙组稍慢,饮水中含镉时无论是足钙组或缺钙组生长均显著
The author attempts to clarify the relationship between cadmium poisoning, calcium deficiency, renal failure and bone disease. Experimental male rats were divided into four groups, five in each group, given different feeds and drinking water. One group fed enough calcium and distilled water (control); two to calcium-deficient feed and distilled water; three to enough calcium and 50 ppm to cadmium; and four to calcium-deficient and 50 ppm to cadmium. Daily measurement of feed and water consumption. Animals were sacrificed 120 days later for histological and biochemical tests. The control group grew well, the calcium-deficient group was slightly slower, and the growth of calcium-
