A Toxicological Study of Polyunsaturated Fatty Acids and Its Application and Research / 医学研究杂志

ABSTRACT

Objective To provide the toxicity basis for safety evaluation of Polyunsaturated Fatty Acids.Methods Acute toxicity test,micronucleus test of born marrow in mice,Ames test,sperm shape abnormality and thirty-day feeding test in rats were conducted in this study.Results The oral LD50 of Polyunsaturated Fatty Acids in both mice and rats were more than 20.0g/kg.BW,so the Polyunsaturated Fatty Acids was classed as actual non-toxicity.The results of micronucleus test of born marrow in mice,Ames test,sperm shape abnormality and thirty-day feeding test in rats were negative.The thirty-day feeding test in rats demonstrated that it had no obvious toxic effects on routine blood,body weight,and biochemical index.No obvious adverse effects dose of this sample was 6.66g/kg.BW.Conclusion Polyunsaturated Fatty Acids toxicity test results showed no obvious toxicity and was safe for edibility.
