本文研究了低硒生态环境中有明显早期大骨节病病变的人群服用富硒酵母、亚硒酸钠和肌肉注射硒代二乙酸后体内硒保留量的动态变化。分析了治疗效应与摄入三种形态的硒后硒在体内保留量的关系,并与对照组作了比较。讨沧了不同形态硒的生物活性。研究结果是三种形态的硒对 In this paper, the dynamic changes of selenium retention in selenium-enriched yeast, sodium selenite and intramuscular injection of selenodiacetate were studied in populations with markedly early Kaschin-Beck disease in low selenium environment. The relationship between therapeutic effect and selenium retention in vivo after the three forms of selenium intake were analyzed and compared with that of the control group. Discuss the biological activity of different forms of selenium. The result is three types of selenium pairs
