Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。

Compared with other methods, the effect on preservation of the cut flowers, pretreated in 100 ml/L benzalkonium bromide for 3 hours, was obvious. The fresh flower weights increased slowly, few or none leaves were wilting after transplanted into water for 6 days. Etiolation of the leave slowed down and almost 90% leaves kept fresh after 12 days. The flower buds blooming speed also slowed down, 50% of flower buds were opened, petals were kept fresh, the stems of cut flower were unbent, and none flowers were drooped after 15 days.

与其他预处理相比，在100 ml/L溶液预处理3h，瓶插后鲜重一直呈缓慢上升趋势；6d后，极少数叶片发生萎蔫，叶片黄化速度也很缓慢，约90％的叶片12d后还可以保持新鲜；花蕾开放速度也缓慢，15d后仅有50％的花蕾开花，且花瓣挺阔，无枯萎迹象，而且茎干挺直，不弯颈；保鲜效果明显高于其他的预处理。
