ration of 1.80 u/ml to use adenosine diphosphate (ADP) of rabbit platelet aggregation induced by the inhibition rate
off 41.8% plus or minus 6.9%, 50.0 + / – 6.3% respectively.Liver lipid peroxidation in mice has obvious inhibitory eff
ect;Can obviously enhance the vitality of catalase in blood of mice.Evening primrose oil, 0.8 g/kg, lavage 1 times a day
90days can make the chronic renal failure rats reduced the volume of urine protein, urine protein selectively improve
