人体长期过量摄入残留农药、重金属和生物毒素可能对身体健康造成损害.因此,中药材和其制剂质量标准中有害残留物的最大限量制定是构成标准的重要组成部分.本文通过查阅大量国外研究报道的有关农药残留、重金属和黄曲霉毒素的毒理学相关实验数据和国内外药品标准,分析有关标准中有害残留物理论最大限量计算方法,模拟计算其最大限量理论值,并将其与中外药品标准中已有最大限量标准进行比较,分析影响限量确定的因素,阐明了标准中有害残留物最大限量制定方法和原则.

Objective:To study the effects of ursolic acid on depressing the blood-fat and raising immunologic function.Methods:The experiments included the small intestinal movement experiments and the carbon clearance capacity test.Results:The experiments results reaealed that the contents of triglyceride was depressed and the contents of high density lipoprotein was raised in normal mouse.Moreover,the carbon movement ratio and the carbon clearing capacity could be increased.Conclusion:The ursolic acid had the effects of depressing the blood-fat and raising immunologic function.
