【摘要】 本实验用不同硒含量串珠酵母人工合成饲料喂养大白鼠,分别于实验前、实验30天及实验40天收集大白鼠24小时尿,尿中酸性氨基多糖含量测定采用氧氯化锆沉淀咔唑硫酸法进行葡萄糖醛酸定量。其结果经F检验各组均无显著差异。发现有以下两个趋势:1.实验30天24小时尿葡萄糖醛酸含量各组普遍升高,40天趋于下降,尤以低硒组显著;2.饲料硒越高,糖醛酸排泄量也越高,与血硒含量作相关分析,各批均呈正相关,但无显著差异。更多还原

【Abstract】 The experiment was carried out on rats fed with synthetic diet containing torula yeasts with different levels of selenium, we collected their urine of 24 hours before the test on the 30th day and the 40th day of the test respectively. The level of acid glycosaminolycan in urine was determined by precipitate carbazole sulfate with zirconium oxychloride （ZrOCl₂） to measure glucuronate. The results by F test showed no significant difference in each group. The following two points have been reached. （a） The glucuronate level general rises in each group on the 30th day and declines on 40th day, especially in the low selenium group.（b） The more selenium the diet contains, the more glucuronate is excreted. The level of glucuronate in urine is correlated with that of blood selenium, with no significant difference.更多还原
