Abstract: The complex asparagus could obviously improve the activities of GST and SOD of mice, healthy persons and tum or patients. After them ice swallowed 40,20,10mg/ml of complex aparagus solution continuously for 18 days, the activities of GST and SOD were tested from their eye ball blood. The results showed that the activities of the two experimental groups are both higher than those of the comparision groups (P<0.01). After 64 healthy persons working in the chemical toxin-polluted environment were given complex asparagus for 18 days, the activities of GST and SOD tested by using their vein blood were improved obviously, compared with themselves (P<0.01,P<0.05) respectively. The activities of the two enzymes of 22 operated tumor patients given complex asparagus per os for 18 days were also improved(P<0.05).
