本实验测定了富硒酵母与亚硒酸钠,在家兔体内的吸收、分布、半减期和小白鼠的半数致死剂量,以及其在人体内的利用率、生物学活性等。结果:富硒酵母态硒吸收缓慢平稳,维持时间长于亚硒酸钠态度的硒;富硒酵母态酵经肾排出缓慢,在组织内保留时间长;富硒酵母硒态的半减期相当长,而亚硒酸态硒的半减期是99小时;富硒酵母态硒的毒性是亚硒酸钠态硒的1/4左右;富硒酵母态硒在人体内的利用率(在发中的保留量)高于亚硒酸钠态的硒;富硒酵母态硒的生物学活性(以X线有效率为指标)高于亚硒酸钠态的硒。
This experiment measured the selenium-enriched yeast and sodium selenite, absorption, distribution in the rabbit body, half-dead and half the lethal dose of mice, and its utilization in the human body, biological activity. Results: The selenium-enriched Yeast selenium absorbed slowly and steadily and maintained for a longer time than that of sodium selenite. Selenium-enriched yeast fermented slowly through the kidneys and retained in the tissues for a long time. , While selenium selenium semi-reduction is 99 hours; selenium-enriched yeast state selenium toxicity is about 1/4 of selenite sodium selenium; Se yeast selenium in the human body utilization rate (in the hair Of the retention) higher than the selenite sodium selenium; selenium yeast selenium biological activity (X-ray efficiency index) higher than the selenite state of sodium selenite.
