以缺锌大鼠为对象,给予4.612 5 mg/kg 体重锌后,观察了不同时间段锌在大鼠各组织的贮留与分布及 24 h尿、粪中累计排锌量和锌的贮留利用情况。结果表明,锌在组织中的贮留与分布不同,肝脏为最高,其次为睾丸、肾、脾、心;24 h 尿锌、粪锌累计排出量约为给予量的 65％,表观贮留率为35.16％。结果提示,该富锌酵母用于防治儿童缺锌症,将取得较好效果。 Zinc-deficient rats were given zinc (4.612 5 mg / kg body weight), the storage and distribution of zinc in different tissues were observed at different time points, and the cumulative zinc release and storage of zinc in 24 h urine and feces Use case The results showed that the storage and distribution of zinc in the tissue were different, with the liver being the highest, followed by the testis, kidney, spleen and heart. The cumulative excretion of 24 h urine zinc and feces zinc was about 65% The rate is 35.16%. The results suggest that the zinc-rich yeast used to prevent zinc deficiency in children will achieve better results.
