查询词典 reduction

The results showed the serum IL-2 levels were significantly lower in the patients than that of the controls(P.05),indicated the imbalance of immune functions,The decreased IL-2 levels may decrease natural killer cells and lymphokine-activated killer cells activity,causing reduction of the virus infected target cytolysis may be one of the important reasons in the recurrence of the disease.

结果发现病人血清IL－2水平比对照组明显降低（P＜0.05），说明该病存在免疫功能失调。IL－2水平低下，导致由IL－2诱生的NK和LAK细胞活性降低，使它们溶解和破坏病毒感染靶细胞能力低下，此可能是该病不断复发的重要原因之一。
