Effects of α-linolenic acid and γ-linolenic acid on the blood-lipid levels in hyperlipidemia people.

Objective:To investigate the effects ofα-linolenic acid andγ-linolenic acid on the blood-lipid levels of the people with hyperlipidemia.Methods:106 subjects who the serum total cholesterol(TC)level≥5.2mmol/L and triglyceride(TG)level≥ 1.65mmol/L were randomly divided into 2 groups,the experimental group was given 3 soft capsules containingα-linolenic acid and γ-linolenic acid at levels of 400mg/d and 120mg/d,respectively.Control group was provided 3 similar soft capsules within placebo.To observe the changes of TC,TG,HDL-C in the plasma and general condition before and after the experiment.The total process need 45 days.Result:As compared with the control group,the serum levels of TG,TC,decreased obviously,and HDL-C increase significantly in the experiment group.As compared with itself,in the experiment group the TG and TC levels in the blood decreased obviously,and HDL-C levels increased significantly at the end of the study.On the contrary,there were no significant difference on the levels of TC TG HDL-C in the control group.The effective power and total effective rate of TC TG and HDL-C in experiment group were more significant than in the control group.There was no abnormal on the mind,sleep,diet,and clinical indicators(e.g.urination,blood pressure) of the volunteers during the total process,moreover,there was no adverse reaction.Conclusion:α-linolenic acid andγ-linolenic acid were able to auxiliary decrease the levels of blood lipids and no adverse effect on the body's health.
